Technical Field

The present invention relates to a split slide valve system for a casting installation, a casting installation and a casting method for producing workpieces, in particular from metallic material, according to the preambles of claims 1, 6, 16 and 18.

Background

From DE 102012101055 a1, a casting plant of and a casting method of are known, in which a plurality of casting units are arranged on a circular table, which casting units are moved successively to and from a casting station by means of the circular table, and in which casting station the melt is introduced into the molds of the casting units by means of a low-pressure and/or counter-pressure casting process.

The object of DE 102012101055 a1 is to combine the advantages of periodic forward transport and the associated time savings with the advantages of sufficient casting quality of the castings, which can be achieved in particular in low-pressure and/or counter-pressure casting processes.

A disadvantage of the method described in DE 102012101055 a1 is that the furnace must be kept in connection with the mould and the casting pressure must be maintained until the melt has cooled sufficiently. Depending on the casting, this may result in the casting apparatus reaching a rest time of several minutes during which no further casting can be performed.

Disclosure of Invention

Starting from this prior art, the object of the present invention is to provide casting devices and casting methods for producing castings, which make it possible to reduce the standstill time of the casting device between the production of two castings in a die casting process, thereby increasing the cycle frequency and the cost-effectiveness of the casting device.

This object is achieved by using a split slide according to the invention according to claim 1, in a casting apparatus according to the preamble of claim 6 by the features of claim 6 and by a casting method according to claim 16 or 18. Further developments and advantageous embodiments are specified in the dependent claims.

The split slide valve system for a casting device, in particular for a die casting device or a gravity casting device, according to the invention comprises a base plate and a slide plate, wherein the base plate has an opening and the slide plate has an th opening and at least second openings, and the split slide valve system is arranged such that it can be brought into a casting position, in which the th opening of the slide plate is at least almost aligned with the opening of the base plate, a pressure position, in which the second opening of the slide plate is at least almost aligned with the opening of the base plate, and a closed position, in which the slide plate closes the opening of the base plate.

Such a split slide valve system makes it possible to open and/or close the passage opening between the mould and the furnace. In addition, the split slide valve system according to the present invention may separate the mold from the furnace after introducing the melt into the mold and simultaneously build pressure on the melt and/or maintain casting pressure within the mold. This is achieved by moving the split slide valve system from the casting position to the pressure position.

It may be advantageous if the funnel plate is arranged on the sliding plate.

The funnel plate serves to facilitate the connection between the gate area of the mold and the nozzle and/or riser of the furnace. Preferably, the funnel plate is formed as a receptacle for a nozzle or riser of the furnace. In order to simplify the accommodation and thus the connection between the mould and the furnace, it is advantageous if the funnel plate has at least partially an inclined inner surface and the nipple has an inclined outer surface complementary to the inclined inner surface.

It may be advantageous if the split spool valve system is at least partially composed of tungsten and/or tungsten alloys and/or ceramic materials.

Tungsten has a very high melting point and is therefore suitable for constructing components for use in casting equipment for processing metallic materials. Furthermore, tungsten does not cause sticking to aluminum and is therefore suitable for use in casting installations and/or split slide valve systems, in which melts of aluminum or aluminum alloys are processed.

It may be advantageous if the distance between the base plate and the slide plate is less than 0.15 mm. In order to minimize the penetration of liquid metal material, in particular aluminum, into the intermediate space between the base plate and the slide plate, it is advantageous to form the distance between the base plate and the slide plate as small as possible, in particular < 0.15 mm.

It may be advantageous if the th opening has a larger flow-through cross-sectional area than the second opening.

A casting apparatus according to the invention, in particular a die casting apparatus or a gravity casting apparatus according to the invention, comprising a mould and a furnace, wherein a split slide valve system according to any of claims 1 to 5 is arranged between the mould and the furnace.

For example, DE 102012101055 a1 discloses casting devices for use in a die casting method in which the mold is separated from the furnace, whereas in casting devices known from the prior art, the mold must remain coupled to the furnace until sufficient cooling of the melt in the mold has taken place to prevent the melt that has not solidified in the mold from flowing out, before decoupling takes place between the mold and the furnace.

The arrangement of the split slide valve system according to the invention between the mould and the furnace makes it possible to close a passage opening between the mould and the furnace, through which passage opening the melt is introduced into the mould from the furnace after the melt has been introduced into the mould. The split slide valve system is either in a closed position or a pressure position.

After the slide valve system has been moved from the casting position into the pressure position or the closed position, the casting pressure generated by the furnace is maintained by a pressure device, in particular a mechanical and/or pneumatic pressure device, instead of the furnace.

In the pressure position of the slide valve system, the casting pressure generated by the furnace can be maintained by a pressure device, in particular a pneumatic pressure device. For this purpose, a pneumatic pressure device generates a gas pressure which acts on the melt, in particular in the casting channel and/or the feeder, and thus increases the pressure on the melt.

In the closed position of the slide valve system, the casting pressure generated by the furnace can be maintained in the mold by a pressure device, in particular a mechanical pressure device. For this purpose, a mechanical slide is moved into the feeder of the mold, increasing the pressure on the melt.

It is also possible to introduce the melt into the mold without additional pressure, for example in a gravity casting process, and to build up and apply a pressure on the melt which is greater than the ambient pressure, in particular greater than the mean atmospheric pressure (1013hPa), only after the introduction of the melt into the mold and the displacement of the slide valve system from the casting position into the pressure position.

Thus, the furnace can be separated from the mould immediately after the melt has been introduced into the mould. After the mold is transferred from the casting station to the cooling station, the furnace may be used for other casting processes. The disadvantageous standstill times of the casting devices described in the prior art are thereby reduced by up to several minutes, and the cycle frequency is therefore increased when casting individual castings.

It is advantageous if the slide valve system is arranged such that it can be brought into the casting position, the pressure position and/or the closed position by means of a relative movement of the mould with respect to the stationary furnace.

By bringing the slide valve system into different positions by means of a relative movement of the mold with respect to the stationary furnace, it is possible to operate the slide valve system without using an additional actuator.

This movement of the split slide to different positions is particularly suitable for use in a casting apparatus that uses a round table to transport the molds. After the melt has been introduced into the mold, the separating slide is automatically moved from the casting position into the pressure position or the closed position by a rotary movement of a circular table which moves the mold from the casting position into the cooling position. Furthermore, this movement of the split slide to different positions is particularly suitable for use in casting equipment that uses robotic arms to transport molds. After the melt has been introduced into the mold, the separating slide is automatically transferred from the casting position into the pressure position or the closed position by a rotary movement or a linear movement of the robot arm.

It may be advantageous if in the casting position the th opening of the slide plate, the opening of the base plate, the gate area of the mould and the nozzle of the melt furnace are arranged with respect to each other to form a channel opening through which the melt is introduced from the melt furnace into the mould.

It may be advantageous if in the closed position the gate area of the mold is completely closed by the slide plate of the split slide valve system.

After the melt has cooled sufficiently, there is no longer a need to maintain the casting pressure. In order to prevent foreign bodies from entering the opening of the gate plate, which could adversely affect the subsequent casting process, it is advantageous to remove the separating slide valve system as quickly as possible, i.e. after the melt has sufficiently solidified and the casting pressure no longer needs to be maintained, from the pressure position to the closed position in which the opening of the slide plate is covered by the base plate.

It may be advantageous if the substrate is integrated in a mould.

The integration of the base plate in the mould makes it possible to arrange the slide plate directly to the outer area of the mould. Thus, parts and therefore costs can be saved.

It may be advantageous if the gate area has a gate channel and/or a feeder.

It may be advantageous if the gate area or the mold is arranged such that a pressure device, in particular a mechanical and/or pneumatic pressure device, is capable of exerting a pressure on the melt in the gate area, in particular in the gate channel and/or the feeder, and thereby maintaining the casting pressure within the mold even after decoupling the split slide valve system and the furnace.

In order to maintain the casting pressure after the melt has been introduced into the mold, pressure is exerted on the melt by means of a pressure device. This may be done on the melt in the sprue channel or an additional feeder may be provided in the mould, the pressure means exerting pressure on the content of the additional feeder to maintain the casting pressure.

The pressure means can be formed as mechanical pressure means and/or as pneumatic pressure means. In the mechanical pressing device, a mechanical slide, which is advantageously arranged on the mold, moves through the mold and exerts a pressure on the melt in the mold, in particular on the melt in the feeder.

The pneumatic pressure device generates a gas pressure which acts on the melt in the mold, in particular in the sprue channel and/or in the feeder. A combination of mechanical and pneumatic pressure devices is also contemplated.

It may be advantageous if the casting apparatus comprises a conveyor means for transporting the mould from the casting station to the cooling station.

After introducing the melt into the mold and moving the split slide valve system from the casting position to the pressure or closed position, the filled mold must be removed from the casting station to provide a casting station for another casting operation.

It may be advantageous if the transportation means comprise a circular table and/or a robotic arm.

The advantage of a round table is that large and heavy castings can be produced by means of a corresponding dimensioning. In contrast, robotic arms are very flexible to use and can rotate the mold or place it in other forms of motion during transport.

It is advantageous if the nozzle of the furnace, in particular of the riser of the furnace, has a tapered end, i.e. in particular the wall thickness of the nozzle of the riser tapers towards the end, which can be coupled to the funnel plate of the slide valve system.

The casting method according to the invention for producing a cast part, in particular from a metallic material, in particular a die casting method or a gravity casting method, comprises the following method steps:

moving the split slide valve system to the casting position,

coupling the split slide valve system with the furnace,

-introducing the melt into a mould,

moving the split spool valve system to a pressure position or a closed position,

decoupling the split slide valve system from the furnace,

placing the split spool valve system in the closed position,

wherein especially process steps 1 and 2 can be carried out in any order, the last process steps are optional and not necessary.

The use of the split slide valve system according to the invention in a low-pressure or counter-pressure casting process in which the casting pressure is maintained directly after the introduction of the melt by means of a pressure device, in particular a pneumatic pressure device, is described below. However, the use of split spool valve systems is not limited to these die casting methods. The split slide valve system according to the invention can also be used in such casting methods, in particular in such gravity casting methods, in which a pressure is built up and applied to the melt only after the melt has been introduced into the mold.

The starting point for the casting process according to the invention is a melting furnace with a melt and a mold which is spatially separated from the melting furnace. The mold is spatially located above the furnace and has the split slide valve system of the present invention at the bottom.

The mould prepared for the casting process is placed in the casting station by means of a transport device. In the casting station, the furnace and/or the mould are moved relative to each other, in particular onto each other, and the furnace is coupled with a separate slide valve system of the mould.

If the slide valve system is not in the casting position, the slide valve system is moved into the casting position by a movement, in particular a lateral movement, of the mold and/or of the furnace.

To this end, casting pressure is applied on the surface of the melt in the furnace and the melt rises through the riser, the th opening of the slide plate, the opening of the base plate and the gate area into the casting mold.

After the melt is completely introduced into the mold, the split slide valve system is moved to the pressure position. The movement of the separating slide system into the pressure position is preferably automated with the transport of the mould from the casting station into the cooling station. Due to the relative movement of the mould with respect to the furnace or vice versa, the separating slide valve system, in particular the slide plate, is moved, in particular laterally moved.

At the end of the movement, the opening of the base plate no longer at least partially coincides with the th opening of the slide plate, but the opening of the base plate at least partially coincides with the second opening of the slide plate.

During the introduction of the slide valve system from the casting position into the pressure position, a pressure is exerted on the second opening of the slide plate by means of a pressure device, in particular a pneumatic pressure device, which corresponds at least as far as possible to the casting pressure of the casting installation.

After the casting pressure in the mold is at least largely maintained by the pressure means, in particular by the pneumatic pressure means, the furnace is decoupled from the separating slide system and the mold is moved further into the cooling station.

To prevent foreign objects from entering the mold, the split slide valve system may be moved to a closed position after the melt in the mold has cooled sufficiently, in which the gate region of the mold is completely closed by the slide plate, the opening of which is closed at least on the side by the base plate.

In order to connect the furnace to the slide valve system, in particular the end region of the stand pipe of the furnace or the nozzle of the furnace is in mechanical contact with a sliding plate of the slide valve system, in particular a funnel plate arranged on the sliding plate. The ends of the risers or nipples are introduced into or slid over the funnel plate.

provides that the slide valve system is placed in a closed position after the melt has been completely introduced into the mould, the movement of the slide valve system to the closed position preferably takes place automatically as the mould is transported from the casting station to the cooling station, the slide valve system, in particular the slide plate, being moved, in particular laterally, as a result of the relative movement of the mould with respect to the furnace or vice versa.

At the end of the movement, the opening of the base plate no longer at least partially coincides with the th opening of the slide plate, but is completely closed by the slide plate.

During the introduction of the slide valve system from the casting position into the closed position, pressure is exerted on the melt in the mold by a pressure device, in particular a mechanical pressure device, which at least approximately corresponds to the casting pressure of the casting system.

After the casting pressure in the mold is at least largely maintained by the pressure device, in particular by the mechanical pressure device, the furnace is disconnected from the separating slide system and the mold is rotated by 180 °.

After rotation, the disconnect spool valve system may move from a closed position to a pressure position. In the pressure position, the opening of the base plate at least partially coincides with the second opening of the slide plate.

During the introduction of the slide valve system from the closed position into the pressure position, a pressure is applied to the second opening of the slide plate by means of a pressure device, in particular a pneumatic pressure device, which pressure at least approximately corresponds to the casting pressure of the casting device.

After the casting pressure in the mold has been maintained at least to the greatest possible extent by the pressure device, in particular by the mechanical pressure device, the mold can be moved further to the cooling station.

It may be advantageous if the mold is rotated about at least axes after the split spool valve system and furnace are decoupled.

The rotation of the mold preferably encloses an angle of between 1 ° and 180 °, in particular 180 °.

It may be advantageous if the mould is rotated by means of a pouring caster or a robot.

It may be advantageous if the split slide valve system is moved into the pressure position after the mold has been rotated about at least axes.

It may be advantageous if the separating slide valve system is brought into the closed position after the mold has been rotated about at least axes and the separating slide valve system has been moved into the pressure position.

It can be advantageous if in the pressure position and/or in the closed position the casting pressure within the mould is maintained by pressure means, in particular by pneumatic and/or mechanical pressure means.

After the melt has been completely introduced into the mold, the casting pressure inside the mold is maintained by external pressure means, in particular by pneumatic pressure means and/or mechanical pressure means, in order to separate the melting furnace from the mold as quickly as possible, but at the same time to maintain the casting pressure inside the mold as long as possible.

It can be advantageous if the casting pressure is maintained on the melt in the pressure position by means of gas pressure, in particular by means of air pressure.

The air pressure is easy to establish, adjust and maintain. Advantageously, a gas is used which does not react or only reacts slightly with the casting material. Thereby avoiding negative effects on the casting.

It may be advantageous if the split slide valve system is moved into the casting position, the pressure position and/or the closed position by means of a relative movement of the mould with respect to the furnace.

The introduction of the slide valve system into the casting position, the pressure position and/or the closed position by a relative movement of the mold with respect to the furnace or vice versa has the advantage that no further drive means are required for operating the slide valve system.

It can be advantageous if the mold is rotated about at least axes and then the casting pressure in the mold is maintained by means of pressure means, in particular pneumatic pressure means.
