Technical Field

The present invention relates to a molding tool system for a die-casting machine for casting castings. The term die casting herein is to be interpreted in a broad context such that the term includes both metal die casting and plastic injection molding in particular. The term casting is not presently used primarily to refer to individual castings, but rather is used as a generic term for describing castings of the same design (i.e., two castings differing in their design in each case). For the sake of distinction, the control castings are now individually referred to as cast products.

Background

In conventional molding systems, there is a close correlation between the casting and the molding tool system produced specifically for the casting. This means that most of the components of a conventional molding tool system are exclusively made only for the casting to be cast and assembled in succession in order to form a molding tool system specific to the casting, also referred to simply as molding tool. This applies, for example, to casting similar parts but not exactly identical in shape, such as in the production of variants of the parts by casting, even in the case of castings having relatively small deviations from one another. The cost of conventional die casting tools is correspondingly high, which in turn results in casting of castings in relatively small quantities or in different variants for producing prototypes and low-volume die casting, which is rather cost intensive. Furthermore, the corresponding tool work and tool re-work of the die casting tool causes the casting operation to be interrupted during the tool work procedure, which compromises economic feasibility.

Typical conventional molding tool systems herein comprise two mold halves, namely one movable and one immovable mold half, and for each of these two mold halves, in each case comprise an insert part and one mold frame, on which the insert part can be built up and which comprises a profile-imparting mold member as well as a non-profile-imparting mold member. The mold frame and the mold member as an insert part are individually adapted to the casting to be cast, and are thus typically specified and adapted to cast only the one casting. The profile-imparting mold members on the mold frame in the assembled position form a casting profile for the casting to be cast, i.e. they determine the profile of the casting cavity, which corresponds to the shape of the casting, and which is filled in the casting procedure with the associated casting material supplied under pressure, such as liquid metal melt or molten plastic material. For example, the guide member, the vent member, and the slider member are portions of the non-contoured imparting mold member. The slider member is particularly useful for casting castings as follows: have undercuts and similar profiles and do not achieve direct demolding and typically include a slider support assembled so as to be immovable and a slider guide assembled so as to be movable thereon.

Conventional die-casting tool systems of this type are disclosed, for example, in patent publication DE 102012019357B 4 and in publications DE 102014103532 a1 and WO 2017/142731 a 1. In DE 102012019357B 4 herein, a die casting tool system with special slider guides provided on the die plate is disclosed. In DE 102014103532 a1, a die-casting tool system is disclosed which is specially conceived for casting the supporting structure of an oil filter module for an internal combustion engine, which is the casting to be cast, and in WO 2017/142731 a1, a die-casting tool system is disclosed which is specially conceived for casting metal components for applications in vehicles, which die-casting tool system herein, depending on wear or erosion, respectively, uses replaceable insert parts as profiled mold components in areas with specific stresses.

The procedure for modularizing the molding tool in order to be able to improve the development process of the molding tool is demonstrated in the theoretical analysis in the following paper by Yann Queudeville: "Entwickling inner method zur modular von Druckguswerkzeugen", Ergebnisse aus Forschung und Entwickling, vol. 19 (2015)), Gie beta erei-institute der RWHTH Aachen, ISBN 978-3-944601-08-3 (Ebook (electronic book)).

Patent publication DE 3542840C 2 discloses a molding tool for plastic injection molding, in which mold inserts are received in a mold plate, wherein a central mold insert is fixedly connected to the mold plate, while laterally adjoining mold inserts can be easily replaced, so to speak, in particular by releasing wedge bars screwed to the mold plate, and can have different sizes and shapes, wherein differences with respect to the maximum length or width of the mold are compensated by a compensation member.

The utility model publication DE 202015101713U 1 discloses a die-casting die which is particularly suitable, so to speak, for the rapid production of prototypes and for this purpose has two die halves which in each case receive in a cavity at least one die insert with a profiled section and optionally a filler and have an annular guide and retaining profile which surrounds the cavity, wherein one or more holders for a slider are provided so as to be adjustable on one guide and retaining profile and a locking section is provided on the other guide and retaining profile, which locking section is aligned in a corresponding manner to the locking section of the slider and, in the case of a closed die, correspondingly locks the slider or the holder of the latter in the set nominal position.

Publication DE 102015015368 a1 discloses a casting mold intended for producing different variants of the composition of a cast part, such as a mounting block for cab mounting of a driver of a commercial vehicle, and for this purpose has a base mold with a container and a casting mold insert, in which container the casting mold insert can be selectively set in a first rotational position for producing a first variant of the composition and in a second rotational position, different from the first rotational position, for producing a second variant of the composition of the cast part. In particular, selective positioning of the casting mold inserts in each case in one of two positions of rotation by 180 ° is disclosed, for which corresponding point symmetry or mirror symmetry of the participating casting mold components is required.

Publication DE 102016121996 a1 discloses a tool element for a tool for plastic injection molding in the following configuration: by means of this construction, the maintenance and replacement of the individual components of the functional unit of the tool element will be simplified. To this end, the tool element in one embodiment as an ejector-side tool half comprises: a first functional unit formed by a mold insert and an ejector facility, the ejector facility being mountable on a rear side of the mold insert with optional interposition of a support plate; and a second function unit including a first holding plate, a second holding plate, a compression plate, and a clamping plate. The first and second functional units are releasably connected to one another by mechanically releasably coupling the injector arrangement and the mold insert to a locking mechanism of the second functional unit, wherein the locking mechanism can be unlocked by means of a user-actuable unlocking lever arranged laterally on the tool half.

Disclosure of Invention

The present invention is based on the technical object of providing a die-casting tool system as follows: the molding tool system enables efficient, flexible and cost-effective casting of castings that are also at relatively low volumes and/or at multiple different casting variations, as compared to conventional molding tool systems mentioned hereinabove.

The invention achieves this object by providing a die-casting tool system having the features of claim 1.

The molding tool system according to the present invention comprises: a floor associated with the machine; at least one set of profile-imparting mold members that form casting profiles on the floor in an assembled position for respective associated castings to be cast; and a plurality of non-contouring tool container module members. The base plate, the tool container module members and the contouring mold members are configured for releasably assembling the associated set of mold members and the assigned set of tool container module members on the base plate, more particularly on the respective fastening sides of the latter, for casting the respective casting.

The term machine-related in this context means that the base plate is configured for a specific use on the associated die-casting machine, i.e. for use on a specific model or type, respectively, or for use on a specific machine size of the die-casting machine, respectively. For a respectively further size or another type of die-casting machine, a further bedplate is used which is correspondingly adapted to the further machine in a different manner.

The respective set of profile-imparting die members determines the shape of the casting cavity and for this purpose is correspondingly determined or defined by the profile of the casting as is known per se in the principle for conventional die-casting tools. In other words, each casting (i.e., each casting cavity) is assigned a specific set of contour-imparting mold members, and each contour-imparting mold member is specifically adapted to that casting and typically can only be used to cast that casting, but cannot be used to cast other castings. The collective contour-imparting mold members associated with a particular casting herein jointly form a corresponding mold insert for that casting, i.e. said contour-imparting mold members, respectively in an assembled state or in their assembled state on a floor, have the function of a mold insert as is well known to the skilled person. Different castings to be cast on the same die-casting machine when using the die-casting tool system according to the invention may differ in particular in their shape and/or size, which is practically free of any restrictions as long as the shape and size of the casting is compatible with the machine dimensions or the dimensions of the floor accordingly.

In a manner which is likewise conventional per se, the non-contouring tool container module component accordingly serves as an additional tool container component or auxiliary tool part, in order in particular to reliably retain the contouring mold component on the floor and to ensure that the casting mold is generally subjected to compressive stresses in the molding process, and in order to appropriately guide and/or temperature control the flow of molten material, and to ensure the necessary venting of the casting cavity, and depending on the contour of the casting, to accordingly effect or facilitate the demolding process. In contradistinction to the conventional systems mentioned above, however, non-contouring tool container members are presently contemplated to be modular and may be used in a correspondingly variable manner, which is why they are referred to as tool container module members.

The base plate on the fastening side has a fastening grid of a plurality of fastening points arranged so as to be distributed in a regular or irregular pattern across the fastening area. This means that the fastening points in the fastening areas are arranged in a two-dimensional grid pattern so as to be offset from each other, preferably at regular, even intervals, in two perpendicular or otherwise non-parallel oblique directions, alternatively at irregular intervals in one and/or the other of the two non-parallel grid directions. The bottom plate thus comprises a plate body embodied as a grid plate and having fastening points in a corresponding grid pattern. The fastening points can in particular be formed by corresponding fastening bores which can receive fastening bolts or other fastening components conventionally used for fastening purposes in die casting tools. Alternatively, for example, at least part of the fastening points can be formed by fastening bolts or fastening pins interacting with corresponding mating fastening components located on the components to be assembled (such as the profiling mold components). Depending on requirements, the fastening region can extend across the entire or almost the entire extent of the fastening side or alternatively only over a partial region of the latter. Due to this fastening grid, the contouring die members and the associated non-contouring tool container module members for the respective castings can be fixed to the base plate in a very flexible manner in variable orientations and/or in variable positions and/or in variable dimensions and/or in variable combinations. The plate plane of the base plate for fastening the mentioned components is accordingly formed according to the defined fastening side (more particularly, the fastening region thereof).

It is understood that the above list of components of the molding tool system is not intended to be comprehensive, but rather to indicate the following components: the component is assigned to one of the two mold halves of the die-casting machine, i.e. to the movable mold half or to the fixed, immovable mold half, and is at least required for implementing the invention. Depending on the requirements and the specific application, the die-casting tool system according to the invention additionally comprises additional components of a conventional type or of a new type specifically designed for the invention. In particular, the molding tool system can comprise a further base plate and/or a further profiled tool member and/or a further non-profiled tool container module member according to embodiments of the invention or conventional embodiments for use on the respective other of the two mold halves.

According to one aspect of the invention, at least one set of the contour-imparting die members, in connection with an assigned set of the tool container module members, can be assembled in at least two different orientations and/or in at least two mutually displaced positions on the base plate (i.e. on the fastening side of the latter), i.e. respectively in two or three or any other number of more than three different orientations or displaced positions. The term orientation in this context means in particular that the profile gives the mould member and the tool container module member a rotational position on the fastening side of the base plate; the term position means in particular a corresponding translational or lateral position on the fastening side of the base plate. In other words, the two different orientations are mainly transformed into each other due to a rotation around a rotation axis perpendicular to the plate plane of the fastening side, wherein the rotation axis is preferably located within the area across which the formation formed by the profile-imparting die member and the tool container module member extends on the fastening side of the base plate, while the two different positions are mainly transformed into each other due to a displacement in a translation direction parallel to the plate plane of the fastening side. In view of the variable assembly possibilities of the mold member and the tool container module member on the fastening side of the base plate, which can be implemented in a functionally reliable manner, which is advantageous in terms of construction, the fastening grid formed on the fastening side of the base plate achieves the best prerequisites.

This aspect of the invention enables the contouring mold member and the non-contouring tool container module member to be secured to the base plate in respective orientations or positions that are optimal for the respective casting to be cast. The optimum position or orientation of the cast part in the molding tool is determined accordingly, in particular, by the geometry of the cast part and the requirements that have hitherto been able to demould undercuts, for which purpose slider members with slider guides having a suitable direction of displacement are typically used. A further parameter for establishing the optimum orientation and/or optimum position of the casting in the casting mold is the design of the feed of the molten material into the casting cavity (i.e. into the mold cavity) which is optimized in terms of production technology and so-called gating (i.e. optimization of the conduit system for the molten material). Depending on the casting to be cast, in one case, for example, the alignment of the slider member or slider guide, respectively, with a displacement direction parallel to the horizontal or vertical machine direction of the die-casting machine may contribute to this, while in another case, the non-parallel, oblique alignment of the slider member displacement direction, respectively, with respect to the horizontal or vertical machine direction may contribute to the casting of another casting.

With the use of this aspect of the invention, it is possible to meet these optimization requirements very simply in a flexible and thus efficient manner, since the set of profile-imparting mold members and the assigned set of tool container module members can be fastened to the floor plate in an orientation or position, respectively, which in each case contributes to the respective case to the greatest extent.

According to further aspects of the invention embodied in addition or as an alternative to the aforementioned aspects of the invention in corresponding embodiments of the invention, there are a plurality of sets of contouring mold members having respectively assigned sets of tool container module members for selective assembly on a floor.

This aspect of the invention enables two or more different castings, i.e. castings of different shapes and/or sizes, to be cast using the same die-casting machine with the same bottom plate. To cast a respective casting, the set associated with the casting is selected from the available sets of contour imparting mold members, and the selected set of contour imparting mold members is secured to the floor in connection with the assigned set of tool container module members.

In contrast to the conventional die casting tool systems mentioned above, in the present invention the base plate, in connection with the contouring mold members and non-contouring tool container module members modified so as to match said base plate, is thus configured for releasably retaining in a variable manner the set of contouring mold members and the assigned set of tool container module members associated with the current casting to be cast in each case in terms of a multiplicity of different possible configurations if required in different orientations and/or at different positions on the base plate, more particularly on the fastening side of the latter.

In the present invention, the bottom plate in combination with the contour imparting die member and non-contour imparting tool container module member assembled as a function of the casting replaces the die frame with an insert portion such as used in the conventional system mentioned hereinabove, and differs from the latter in the ability of the bottom plate to: the contouring mold members and non-contouring tool container module members can be maintained in at least two different configurations, i.e., respectively two or more different orientations or positional arrangements, of the same contouring mold members and non-contouring tool container module members (i.e., arrangements having different sets of contouring mold members and assigned non-contouring tool container module members for casting different castings) for casting a particular casting. In contrast, the mold frames in the noted conventional systems are typically conceived for holding only a very specific set of tool members for casting the assigned castings; the other mould frame with the other tool member or insert part held thereon is correspondingly used for casting another casting.

The invention thus enables an efficient and flexible use of the same base plate for casting different castings and/or for casting castings in a positional configuration which is in each case optimally modified in terms of the orientation of the respective die-casting tool or die-casting machine. Furthermore, at least part of the non-contoured tool container module components, when required, can be flexibly and efficiently used in a modular manner for casting different castings or for casting with different positional orientations of the castings or casting cavities, respectively. The fastening grid can easily be constructed in a manner that results in: the fastening grid enables a relatively large number of different positioning of the respective sets of profile-imparting mold members and the assigned sets of tool container module members in a mutually displaced and/or rotated manner, and likewise enables the use of the sets of profile-imparting mold members and the assigned sets of tool container module members for castings which differ not only in their dimensions, or are related in terms of symmetry, but nevertheless have completely different shapes.

In a refinement of the invention, the fastening grid is formed by a two-dimensional field of fastening points in which the fastening points are arranged in a plurality of successive parallel rows spaced apart from one another in a row spacing direction which is non-parallel (i.e. perpendicular or oblique) to the row direction. This represents an advantageous population of fastening areas resulting from fastening points, which enables a high degree of flexibility in terms of assembly of the profiled and non-profiled tool container module members on the floor. In an alternative embodiment, for example, the fastening points can be arranged in an irregular, randomly distributed grid pattern.

In a refinement of the invention, the first and second of the at least two different orientations are rotated relative to each other about an axis which is perpendicular to the base plate and which is located in the fastening region. This represents an advantageous embodiment in view of the flexible assembly possibilities for the assigned sets of mold components and tool container module components in different orientations on the floor given to the contours of the respective castings. For example, the slider member can thus be arranged parallel to the plate plane of the bottom plate, so as to have different displacement directions relative to the horizontal plane or respectively the vertical plane machine direction depending on the casting to be cast, in order to achieve respectively an optimal position or orientation of the casting cavity when all casting conditions are taken into account. In an alternative embodiment, the axis of rotation extends outside the fastening region.

In a refinement of the invention, at least one of the non-contouring tool container module components is associated with at least two of the set of tool container module components. This aspect of the invention increases the efficiency and flexibility of the die casting tool system in that the tool container module member or a corresponding tool container module member can be used not only for casting a single specific casting, but also for casting two or more different castings.

As an extreme case, these possibilities include that all non-contouring tool container module components are associated with at least two sets of tool container module components, i.e. can be used for casting two or more different castings, and/or that one or more non-contouring tool container module components are associated with all sets of tool container module components, i.e. can be used for casting all predefined different castings.

In a refinement of the invention, at least one of the non-contouring tool container module members is not associated with at least one of the set of tool container module members. This perfection thus relates to the following cases: wherein not all non-contouring tool container module members are used or required accordingly for each of a plurality of castings to be cast in combination with a respective contouring mold member.

In a refinement of the invention, the non-contouring tool container module component comprises at least one slider component and/or at least one guide component and/or at least one ventilation component and/or at least one centering plate. In this refinement of the invention, as regards the function of the respective tool component, which is also used in conventional systems, the respective tool component (i.e. the slider component(s), the guide component(s), the ventilation component(s) and the centering plate (s)) thus forms in each case one of the non-profile-imparting tool container module components and can thus be used correspondingly in a modular manner for casting different castings on the floor and/or in different orientations.

In a refinement of the present invention, the non-contouring tool container module components comprise a first machine type-specific group of one or more tool container module components and a second machine type-spanning group of one or more tool container module components. Machine type specific groups herein are understood to be those non-contouring tool container module members which are designated and contemplated for use in a particular type or particular machine size die casting machine, respectively. Contrasting machine type spanning groups will be understood as those non-contour imparting tool container module members that can be used in a spanning type or size manner, respectively, for different types or sizes of die casting machines, respectively, and are correspondingly contemplated therefor. The adaptability of this second group of tool container module members across machine types furthermore improves the modularity and thus the flexibility of the moulding tool system.

In an embodiment of the invention, at least one guide member and/or at least one ventilation member and/or at least one centering plate is associated with the first group of non-contour forming tool container module members. The group of components, such as the base plate, can be built or constructed in a machine-related manner.

In an embodiment of the invention, at least one slider member is associated with a second group of non-contoured tool container module members. This design embodiment provides, for example, a prerequisite for a facilitated use of one or more slider members for casting parts in die-casting machines of different types or different machine sizes, respectively, for which the slider members can be fastened to a baseplate configured for the respective die-casting machine.

In a refinement of the invention, at least one of the single available set of contour-imparting die members or the plurality of available sets of contour-imparting die members forms a die insert which is designated for assembly as a functional unit on the fastening side of the base plate and on the rear side of the base plate which faces the base plate with a clearance in connection with the ejector. The ejector plate unit is receivable so as to be axially movable in an ejector-related void of the mold insert, one or more ejector pins are coupled to the ejector plate unit for movement, and, by way of an ejector coupling unit, the ejector plate unit is releasably coupleable to an ejector plate actuator unit proximate the floor.

Due to this configuration, the profile-imparting mould member(s) to be assembled on the base plate for casting the respective set of associated castings can be prepared in advance as functional units, i.e. in the case of a plurality of profile-imparting mould members, the latter can be assembled to form the corresponding functional units respectively or be held together by pre-assembly before the profile-imparting mould members are fastened to the base plate as the thus formed functional units.

The functional unit, which in this way acts as a mold insert on the side of the functional unit that faces the bottom plate or the fastening side (i.e. the rear side) of the latter, respectively, during assembly, has a clearance in connection with the injector, the descriptive reference being intended to indicate that said clearance is in connection with receiving the injector member. The mentioned ejector plate unit is in particular receivable so as to be axially movable in said void, wherein the ejector plate unit is releasably coupled to the ejector plate actuator unit proximate the base plate when the mold insert is assembled on the base plate by the set of profile-imparting mold members. As the name indicates, the ejector plate actuator unit serves as an actuator unit for activating the ejector plate unit and is located in a manner known per se in such a way as to be close to the floor (typically behind the rear side of the latter). The injector pin(s) can be activated by the actuator unit in a desired manner, likewise known per se, by means of an axially movable injector plate unit.

In general, this perfection of the invention facilitates the replacement of a set of mold members for a die-casting machine (and in particular also for the contouring when casting a casting of another shape and/or size) to achieve short tool times. In an alternative embodiment, it is contemplated that the contour-imparting die members are assembled individually on the floor and/or the ejector plate unit is assembled in the void of the floor.

In an embodiment of the invention, the ejector plate unit is kept pre-assembled on the functional unit of the mold insert. This embodiment thus very advantageously achieves that the ejector plate unit is integrated on the base plate in connection with the ejector plate unit integrated therein in the functional unit that imparts the assembled contour to the set of mold members and the set of mold members that imparts the assembled contour to the set of mold members as functional units. This achieves that the injector plate unit is assembled on the base plate in one assembly procedure in connection with the mold insert functional unit formed by the profile imparting mold member or the mold member, thereby further contributing to achieving a short tool operation time in the replacement of the molding tool. Alternatively, the ejector plate unit can be assembled on the floor separately from the contouring mold member(s), for example, prior to assembly of the contouring mold member(s).

In an embodiment of the invention, the molding tool system comprises an actuatable retaining bolt unit for releasably securing the mold insert to the securing side of the base plate. The use of an actuatable retaining bolt unit enables a corresponding automation of the assembly of the mold insert functional unit on the base plate by means of a corresponding actuation of the retaining bolt unit. Alternatively, the assembly of the mold insert functional unit can take place manually, i.e. when using a corresponding fastening component to be handled manually.

In an embodiment of the invention, at least one slider member and the associated set of contour imparting die members are designated for releasably retaining slider members preassembled on the associated die member(s). This enables advantageous preassembly of the slider member(s) associated with the assigned set of contour-imparting die members onto the respective set of die member(s), which results in unnecessarily exclusively assembling the slider member(s) onto the base plate. Alternatively, the functional unit formed by the collection of contour imparting die members and the one or more slider members preassembled thereon can be assembled as a solid body on the base plate. This contributes to achieving short tool working times, in particular also when changing the die casting tool for another casting to be cast. Alternatively, the slider member(s) can also be additionally built in a special way on the base plate or fastened without preassembly on the base plate to the collection of profile-imparting die members.

Detailed Description

The embodiment of the molding tool system according to the invention shown in detail in fig. 1 to 8 and further embodiments thereof will be discussed in more detail below with the aid of fig. 1 to 8. The die casting tool system is contemplated and designated for use in a die casting machine 13, the die casting machine 13 being schematically indicated in fig. 1 and used to cast a casting by means of a die casting technique. The die-casting machine 13 can be in particular a metal die-casting machine, for example of the cold chamber type or of the hot chamber type, for die-casting castings from aluminum, magnesium, zinc or another common metallic casting material, or alternatively a plastic injection-molding machine for producing castings from plastic material by means of injection-molding techniques. The die-casting machine 13 in this context can accordingly be of any machine type or machine construction known per se and have machine dimensions known per se, wherein only the inventive uniqueness of the die-casting tool system has to be discussed here, while furthermore reference can be made to technical knowledge and the prior art in respect of further details of the die-casting machine 13. Depending on the embodiment of the system herein, the molding tool system according to the present invention can also be selectively used for different types and/or machine sizes of mold-casting machines 13 when required. As is usual, as can be seen from fig. 2, the die-casting machine 13 comprises a movable mould half 9 and a non-movable mould half 10, on or between which the die-casting tool system is respectively disposed.

As visualized in the form of a block diagram in fig. 1, the molding tool system shown therein comprises a base plate 1, the base plate 1 being embodied in a machine-related manner, i.e. the base plate 1 is designated for use or assembly, respectively, on a molding machine 13 for which the molding tool system is designated. The molding tool system further comprises: a plurality of 3₁₁To 3_1pAt least one first set 3 of₁The profile-imparting die member 3 of (1), p being an arbitrary natural number exceeding one; and a plurality of 2₁To 2_nIs a random number exceeding one, n is an arbitrary natural number. Form a corresponding set 3₁Is given to the mould member 3₁₁To 3_1pThe number p and the shape of (a) vary depending on the casting to be cast. The profile-imparting mold member(s) 3 contiguously form herein a mold insert 3, currently correspondingly designated with the same reference numeral, or corresponding in its entirety to a mold insert as conventionally understood by those skilled in the art.

The base plate 1, the contouring mold members or the mold inserts 3 respectively formed by the latter, and the non-contouring tool container module members 2 are designated for releasably assembling respective sets 3 of contouring mold members 3₁And the entirety 2 of the tool container module component 2 is given a non-contour from the base plate 1 (more specifically, from the fastening side 1a of the base plate 1 which meets the purpose)₁To 2_nSelected tool containerAssigned set W of machine module components₁As can be seen from each of fig. 2 to 8, for example, in order to cast a corresponding casting using a die-casting tool system. For this purpose, the profiling mold component 3 in the assembly position on the base plate 1₁₁To 3_1pOf the corresponding set 3₁A casting profile 12 for the casting to be cast is formed. A special embodiment of the casting profile 12 is schematically illustrated in an exemplary manner in fig. 2 to 5.

It is understood that in each case the base plate 1 and the set of contour-imparting tool members 3 assembled correspondingly on the base plate 1 or on its fastening side 1a and the associated set of non-contour-imparting tool container module members 2 assembled correspondingly on the base plate 1 or on its fastening side 1a in the molding tool system typically appear once for each of the two mold halves 9, 10 of the molding machine 13, as can be seen from the cross-sectional view in the exemplary embodiment of fig. 2. An ejector mechanism 11, which is indicated schematically in fig. 2 for example and known per se to the person skilled in the art, is typically assigned to the bottom plate 1 in position close to the movable mold half 9 herein, which therefore does not require a detailed explanation.

The base plate 1 on the fastening side 1a of the base plate 1 comprises a fastening grid of a plurality of fastening points 14 (in particular fastening bores) arranged so as to be distributed in a regular or irregular pattern across the fastening area Bb as can be seen from fig. 3 to 6, wherein the fastening points 14 are not plotted in the views of fig. 3 and 4 for the sake of simplicity. In the example shown, the fastening region Bb extends substantially across the entire extent of the fastening side 1 a; alternatively, the fastening region Bb extends only across a sub-region of the fastening side 1a, for example only across a central region of a region of the fastening side 1a having, for example, a range of at most 50 to 80% of the area of the fastening side 1a in terms of area. The fastening bore 14 is capable of receiving a fastening bolt or other fastening member in a die casting tool that is conventionally used for fastening purposes.

In a corresponding embodiment of the molding tool system according to the invention, the single first set 3 of profile-imparting die members 3₁Wheel (D)Profile-imparting mold member 3₁₁To 3_1pOr correspondingly to a plurality of sets 3 of mould members 3₁、3₂… … at least a first set 3₁And an assigned set W of non-contouring tool container module members 2₁Can be assembled in at least two different orientations and/or in at least two displaced positions on the soleplate 1. To this end, fig. 2 and 3 visualize a first variant of the assembly, and fig. 4 and 5 visualize a second variant of the assembly, wherein the first orientation P as can be seen in particular from fig. 3₁Different from the second orientation P as can be seen from figures 4 and 5₂. The term orientation in this context means the assigned set W of the contouring mold component 3 and the non-contouring tool container module component 2₁The spatial position and in particular the rotational position with respect to the base plate 1.

The different orientations P herein₁、P₂Or respectively positioning is to be understood such that at least one of the components to be assembled on the base plate 1 (i.e. at least one of the profiling mold component 3 and the non-profiling tool container module component 2) can be provided on the base plate 1 in a correspondingly different orientation or respectively shifted positioning, wherein, depending on the requirements and the specific application, in each case all other components can be assembled identically so as to be respectively oriented or positioned differently on the base plate 1 or respectively in the same orientation or position. The respective different orientations or positions of the mold elements 3, at least for the profiles, are typically carried out in order to form on the base plate 1 cast profiles 12 formed by the latter in respectively different orientations or positions. In many examples, one or more non-contoured tool container module members 2 are furthermore capable of being assembled in correspondingly different orientations or positions on the floor 1.

The contouring mold members 3 are individually adapted to the casting to be cast, while the non-contouring tool container module members 2 do not participate in determining the casting contour 12 for the casting to be cast, and therefore, depending on the embodiment of the system, it is possible to resort to the non-contouring tool container module members 2 in a variable and flexible manner in order to facilitate the determination of the casting contour 12 for the casting to be castThe complete tool set is assembled for the respective casting. For forming respective collections W for casting respective castings herein₁Suitably from all non-contours to the whole 2 of the tool container module member 2₁To 2_nAnd (4) selecting. The non-contouring tool container module component 2 can serve in particular to support a secure mounting of the contouring mold component 3 on the base plate, for example by means of a suitable form-fitting and/or force-fitting connection between the non-contouring tool container module component on the one hand and the contouring mold component 3 on the other hand, so that the required strength and dimensional stability of the tool components (including the contouring mold component 3) assembled in a modular manner on the base plate with respect to compressive stresses occurring during the casting procedure is ensured.

As already mentioned, in the corresponding embodiments of the invention, in each case a profile-imparting die member 3 for selective assembly on the base plate 1₁₁To 3_1pA plurality of sets 3 of₁… …, and 2, integral with a non-contoured tool container module member 2₁To 2_nAn assigned set W of selected tool container module components₁… … are present in connection so that a corresponding plurality of different castings can be cast by means of a die-casting tool system while using the same base plate 1. To this end, an embodiment of the system is shown in fig. 1, except for the profile-imparting die member 3₁₁To 3_1pFirst set 3 of₁In addition, the system also includes means for selectively and in each case casting an assigned set W of tool container module members 2 for casting a first casting G1, a second casting G2 or a third casting G3, respectively₁、W₂、W₃Profile-imparting die member 3 assembled contiguously on base plate 1₂₁To 3_2qOr 3₃₁To 3_3rTwo further sets 3 of₂、3₃Q and r are any natural number exceeding one. In other embodiments, the molding tool system includes only one or two sets of contouring mold members 3 (e.g., set 3)₁And set 3₂) Or more than three setsAnd in each case comprises a corresponding number of assigned sets W of tool container module components 2₁、……。

In an advantageous embodiment, the fastening grid is formed by a two-dimensional field of fastening points 14, as in the illustrated example of fig. 6, wherein the fastening points 14 are arranged so as to extend in a plurality of rows 14 extending in parallel in the row direction Rz_Z1、14_Z2、……、14_ZnAre spaced apart from each other, wherein the rows 14_Z1、14_Z2、……、14_ZnSpaced from each other along a row spacing direction Rs that is non-parallel to the row direction Rz. As can be seen from fig. 5 and 6, the row direction Rz and the row spacing direction Rs in the illustrated example are in particular mutually perpendicular, i.e. it can be said that the fastening points 14 are arranged in rows and columns. In the example shown, the fastening points 14 of in each case two adjacent rows are arranged so as to be offset in the center, i.e. so as to be offset by approximately half of their spacing in the row direction Rz. In an alternative embodiment, the row direction Rz and the row spacing direction Rs run so as to be inclined to one another and/or the fastening points 14 of two adjacent rows are arranged in each case so as not to be offset or in any case offset in the center. Optionally, additional fastening points 14 (such as the fastening point 14a shown in an exemplary manner in fig. 6) can be provided in addition to the mentioned rows or respectively outside the latter, depending on the requirements. Likewise, some of the fastening points 14 shown in fig. 6 can optionally be absent in one or more rows, i.e. not all fastening points 14 have to be arranged at exactly the same distance from one another in the respective row.

The assembly of the various components on the base plate 1 can take place when using screw connections, for example, for which purpose the base plate 1 in the corresponding embodiment is provided with a regular or irregular pattern of fastening bores which can receive threaded bolts or similar fastening bolts by means of which the respective tool components are respectively releasably fastened to the base plate 1 in the desired position or orientation.

In a corresponding embodiment of the molding tool system according to the invention, at least two of the mold members 3 are profiledA set 3₁、3₂And correspondingly non-contouring the entirety 2 of the tool container module component 2₁To 2_nAt least two assigned sets W₁、W₂… … exist in a manner that results in: at least one of the non-contouring tool container module members 2 and the non-contouring tool container module member 2₁To 2_nSet W of₁、W₂… … are associated. Thus, fig. 1 visualizes in an exemplary manner the following: wherein, it is a module component 2₁In the form of a non-contoured tool container module component 2_fWith a collection W for casting a first casting G1₁Associated with and set W of non-contouring tool container module members 2 for casting a second casting G2₂And (4) associating. In a similar manner, the module component 2_n-1First set W of non-contouring tool container module members 2 for casting first casting G1 and third casting G3, respectively₁And a third set W₃Are associated with and, in each case, a module component 2₃And a module member 2_n-2All three sets W of non-contouring tool container module members 2 corresponding to casting of the first casting G1, the second casting G2, and the third casting G3₁、W₂、W₃Are all associated.

In a corresponding embodiment, the at least one non-contouring tool container module component is not associated with the set W of tool container module components 2 used for casting the respective associated casting₁、W₂、W₃Is associated with at least one of the other. In fig. 1, in the form of a modular component 2₂A modular component 2 of the form_gThus not imparting a set W of tool container module members 2 with the non-contour for casting the first casting G1₁Is not associated with the third set W either₃Are associated with, but only the second set W₂And (4) associating. In the exemplary embodiment of fig. 1, the module component 2₁In a similar manner only with the first set W₁And a second set W₂Is associated with and not associated with the third set W₃In connection with, modular components2_n-1Only with the first set W₁And a third set W₃Is associated with and not associated with the second set W₂Are associated with and the module member 2_nOnly with the third set W₃Associated with, but not with, the first set W of tool container module members 2₁And a second set W₂And (4) associating.

In a corresponding embodiment, the entirety 2 of the non-contoured tool container module member 2₁To 2_nComprising at least one slider member 4 and/or at least one guide member 5 and/or at least one ventilation member 6 and/or at least one centering plate 7. The following embodiments are illustrated in an exemplary manner in fig. 2 to 5: wherein the ventilation member 6, the plurality of slider members 4, the plurality of guide members 5 and the plurality of centering plates 7 serve as non-contouring tool container module members.

In the corresponding embodiments herein, in each case at least one centering plate 7 and a plurality of profile-imparting die members 3 associated with the respective casting are assembled on each of the two base plates 1 for the movable die half 9 and the fixed die half 10, as can be seen in the example of fig. 2. Usually, one or more slider members 4 and likewise one or more guide members 5 are assembled on each of the two base plates 1 in each case.

In an advantageous embodiment of the die-casting tool system, the entirety 2 of the tool container module member 2 is given a non-contour₁To 2_nA first machine type-specific group MG1 comprising one or more non-contouring tool container module members 2 and a second machine type-spanning group MG2 comprising one or more non-contouring tool container module members 2. Fig. 1 visualizes an example with a plurality of non-contouring tool container module members 2 in each case in each of the two groups MG1, MG 2. Non-contouring tool container module components, such as those used in a machine-type-specific or machine-size-specific die-casting machine 13, respectively, are specifically contemplated to be associated with the machine-type-specific group MG 1. That which can be used in two or more die-casting machines 13 of different machine types or machine sizesSome non-contouring tool container module members are associated with the machine type spanning group MG2, for which purpose they are specifically conceived for assembly on their respective bottom plate 1 and meet respective casting conditions, such as being subjected to respective compressive stresses during the casting procedure.

In corresponding embodiments, the guide member(s) 5 and/or the vent member(s) 6 and/or the centering plate(s) 7 are associated with a machine type specific group MG1 of non-contour-imparting tool container module members 2, and/or the slider member(s) 4 are associated with a group MG2 of non-contour-imparting tool container module members 2 that can be used in a machine type spanning manner.

As can be seen in particular by means of fig. 3 to 5, in two system variants with different assembly orientations shown here (in which the profile-imparting die member 3 is assembled in particular on the floor 1), two different orientations P₁、P₂Rotate relative to each other about an axis 8 perpendicular to the base plate 1. As in the example shown, the axis 8 is preferably situated in the fastening region Bb, as can be seen from fig. 2 and 4. In the case of FIG. 3, orientation P₁Aligned so as to be parallel to the side faces of the bottom plate 1 and thus respectively to the horizontal or vertical plane, the machine direction of the die-casting machine 13; in the case of fig. 4 and 5, at least the orientation P of the profile-imparting die member 3₂Inclined to the sides of the base plate 1. When required, this can be used to form the casting contour 12 in a spatial position on the base plate 1, which is facilitated in view of optimizing the relevant casting parameters, since the contour is given to the mould member 3₁₁To 3_1p、3₂₁To 3_2q… … associated set 3₁、3₂… … are assembled accordingly. Furthermore, the direction of displacement of the slider guide of the slider member 4 can also be optimally selected in order to accordingly match the shape of the castings G1, G2, … … or the casting profile 12 to be cast, since for example the slider member 4 is assembled in a corresponding orientation on the base plate 1.

In an advantageous embodimentThe outline-giving die member 3₁₁To 3_1pSet 3 of₁Is designed for assembly as a functional unit on the fastening side 1a of the base plate 1 and has, on its rear side 3a facing the base plate 1, an ejector-related recess 3b, wherein, in this case, the base plate 1 is typically a base plate 1 provided for a movable mold half, since, as already mentioned above in the context of the ejector mechanism 11, the ejection of the casting generally takes place there. An embodiment of this type is illustrated in fig. 7. The ejector plate unit 11a, to which one or more ejector pins 11b are coupled so as to be movable, can be received so as to be axially movable in the ejector-related interspace 3b of the mold insert 3.

The ejector plate unit 11a by way of the ejector coupling unit 11c can be releasably coupled to the floor-side ejector plate actuator unit 11 d. This means that, with the mold insert 3 assembled on the base plate 1, the ejector plate unit 11a and thus the ejector pin(s) 11b are releasably coupled to the ejector plate actuator unit 11d and can thereby be driven by the ejector plate actuator unit 11d in order to carry out the desired axial ejector movement, which corresponds to the ejector mechanism 11 mentioned in the context of fig. 2.

The injector-related recess 3b can also be referred to as a so-called injector box and contains all injector components required for the injection of the casting, for which purpose an axial lifting movement sufficient for reliably injecting the casting is provided for the axial movement. In the example shown, the injector pin 11b is fixed by means of a mushroom-shaped head end to two thin injector plates 11a forming an injector plate unit 11a₁、11a₂In the meantime. Hereby, it is achieved in a simple manner that in the case of a plurality of injector pins 11b as in the example shown, all injector pins 11b can be displaced simultaneously in an axial manner. The injector coupling unit 11c is implemented in a manner known per se to the person skilled in the art, which does not require any further explanation here, and the injector coupling unit 11c is realized in the assembly of the mold insert 3 to the mold insert 3The ejector plate unit 11a is desirably coupled to the ejector plate actuator unit 11d when on the base plate 1. In the example shown, the axial driving movement or the conversion of the associated axial injector force from the injector plate actuator unit 11d takes place by means of the push rod 15, respectively, the injector plate actuator unit 11d preferably being formed by a conventional universal injector plate pack with a general interface to the hydraulic system of the proximity machine. The injector coupling unit 11c is preferably designated so as to be controllable from the insertion side of the molding tool system and is preferably equipped with suitable control intelligence known per se to those skilled in the art for this particular application. For improved understanding, it will be mentioned that the insertion side of the system in the view of fig. 7 is at the top and that the rear side of the molding tool system facing away from the insertion side is at the bottom. The ejector coupling unit 11c is particularly designated for automatically establishing or releasing the coupling between the ejector plate unit 11a and the ejector plate actuator unit 11d, respectively, simultaneously with the assembly of the die insert 3 on the base plate 1 or the release of the die insert 3 from the base plate 1, respectively.

In an advantageous embodiment, the ejector plate unit 11a can be preassembled on the functional unit of the die insert 3 and can in this way be kept preassembled on the latter before the die insert 3, in this case in connection with the ejector plate unit 11a on the base plate 1, as is also the case in the exemplary embodiment of fig. 7.

In a corresponding embodiment, as in the illustrated example of fig. 7, when using the actuatable retaining bolt unit 16, it may happen that the mold insert 3 is assembled on the fastening side 1a of the base plate 1 or that the mold insert 3 is released from the fastening side 1a of the base plate 1, respectively. For this purpose, as known per se to the person skilled in the art and only schematically indicated in fig. 7, embodiments for a retaining bolt unit 16 preferably having a plurality of retaining bolts to be attached and released in a correspondingly automatically controllable manner can be used.

In an advantageous embodiment, at least one slide, as visualized in the embodiment according to fig. 8, is providedAn actuator member 4 and a profile-imparting mold member (e.g., mold member 3)₁₁To 3_1p) Associated set of (e.g., set 3)₁) Designated for releasably retaining slider members 4 preassembled on the associated mold member(s), i.e. the mold insert 3 formed by the latter. In particular, for this purpose, the slider hydraulic unit 4c and the slider attachment 4b and the further standard functional group of sliders 4a, in particular in the form of guide members and locking members, are shown in the fragmentary sectional view of fig. 8 for at least one slider member 4 as slider member parts known per se to the person skilled in the art, the slider attachment 4b likewise being embodied in a general manner so as to be profiled in an individual manner for the casting and for this purpose to give the assembled set 3 of mold members together with the profiling₁(i.e. with the mold insert 3 assembled for the casting to be cast). In a similar manner to fig. 2, the base plate 1 for the stationary mold half as well as the movable mold half and the associated mold insert 3 (the latter in each case being assembled on the fastening side 1a of the base plate 1) is shown in section in fig. 8.

Said slider member and thus the slider member(s) 4 in the shown example of fig. 8 are generally connected to the respective mold insert 3 and are additionally screw-fitted to the respective mold insert 3 by means of the respective anchor cam 17 and the assigned screw connection. It is thus not necessary to additionally fasten the respective slider component 4 to the respective base plate 1 or to the basic structure of the system, which ends up close to the insert at the respective base plate 1. More precisely, the respective slider member 4 can be supported in a self-acting manner on the corresponding bearing surface area on the fastening side 1a of the respective base plate 1 during operation of the die-casting machine or die-casting tool system, respectively, in order to absorb the pressure and compression forces caused by the respective slider member 4 during the mold filling procedure. On the other hand, the slider member(s) 4 are preassembled to the mold insert(s) 3 or in each case form the mold insert 3, respectivelyIs given to the mould member 3₁₁To 3_1pSet 3 of₁It is achieved that rapid tool operation of the die-casting machine is carried out with the components of the die-casting tool system required for casting the respective desired casting, without the basic construction of the system (i.e. the respective base plate 1 and the system components adjoining the latter on the rear side, so that for this purpose they have to be removed from the die-casting machine).

In a corresponding embodiment, the invention furthermore enables a rather quick and simple operation of the tool work and tool re-work of the die-casting machine when a casting of another shape and/or size is to be cast. To this end, it is sufficient that the respective set of profile-imparting die members and the associated tool container module members are assembled or disassembled accordingly, while the basic composition of the molding tool system (including the base plate) can remain unchanged. Accordingly, the entire tool work or tool reworking procedure for changing the tool when a casting of another shape is to be cast can take place correspondingly completely from the insertion side of the tool system or from the die casting machine without the intervention required for disassembling the basic composition or for the assembly or disassembly measures of the basic composition. The set of profile-imparting die members in the corresponding embodiment can be provided so as to be preassembled when required so as to comprise the associated ejector member and slider member, and the thus formed functional unit can be incorporated in the die-casting machine and assembled and fixed on the respective bottom plate from the tool insertion side, preferably in an automatic or partially automatic manner and as a solid when using the corresponding actuatable holding bolt unit together with the holding bolts or alternative fastening components to be attached and released in an automatic manner.

As highlighted by the exemplary embodiments shown and further explained above, the present invention makes available an advantageously modular die-casting tool system which enables a modular and thus flexible and variable use of tool members for casting castings of different shapes and/or in different orientations of the casting profile, depending on the machine direction of the die-casting machine which can be assembled on the base plate. The invention thus also offers the advantage of low-volume production of castings and castings, in particular for the casting of prototypes.
