Furthermore, the molding compound, in particular the blank, is provided with at least layers at least in some regions, in that a liquid starting material for producing the layers is introduced, in particular injected, into the mold and applied to at least the some regions, in particular at least toward the some regions, while the molding compound, in particular the blank, is in the mold.

Disclosure of Invention

The object of the invention is to further develop a method and a component of the type mentioned at the outset in such a way that particularly advantageous properties of the component can be achieved in a particularly cost-effective manner.

According to the invention, this object is achieved by methods having the features of claim 1 and by components having the features of claim 15.

In the method according to the invention for producing a component, in particular a component for a motor vehicle, a molding compound for producing the component is introduced into a mold, in particular an extrusion mold, wherein the molding compound has at least synthetic resins as matrix, that is to say as plastic matrix, wherein the molding compound has at least fillers which are embedded in or accommodated in the matrix, wherein after the molding compound is introduced into the mold, the molding compound introduced into the mold and thus present in the mold is extruded by means of the mold and is thereby shaped into a blank, wherein the molding compound, in particular after the molding compound has been shaped into a blank, is provided with at least layers at least in partial regions in that a liquid starting material for producing the layers is introduced, in particular injected, into the mold and is applied to at least partial regions, in particular is injected at least toward the partial regions, while the molding compound, in particular the blank, is present in the mold.

In other words, the molding material, for example in a mold, is provided with the layer before and/or during and/or after its formation. In particular, it is provided that the blank is provided with the layer such that the molding compound is provided with the layer during and/or after the molding compound has been formed into the blank in such a way that: the liquid starting material is introduced, in particular injected, into the mold and applied to at least some regions, in particular injected at least toward some regions.

Provision is preferably made for the starting material in the liquid state to be introduced, in particular injected, into the mold and to be applied at least in some regions, in particular to be injected at least toward some regions, without the molding material or the blank being removed from the mold after the molding material has been formed and before the starting material is introduced or injected into the mold. In other words, the molding material is not removed from the mold after the molding material has been formed into a blank and before the starting material is introduced into the mold, so that the molding material remains in the mold after the molding material has been formed into a blank and is provided with the starting material which is liquid first at least in some regions. The first liquid material, for example, can then solidify, so that the first liquid material becomes solid. The solidified material thus forms, for example, a solid or inherently rigid layer.

In order to now be able to achieve particularly advantageous properties of the component in a particularly cost-effective manner, it is provided according to the invention that a metal starting material is used as the starting material, from which the layer is produced as an at least substantially homogeneous layer for electromagnetic shielding. Thus, for example, the starting material is a melt or a melt of a metal (this melt is also referred to as a metal melt) in its liquid state, in which the starting material is introduced into the mold and is applied at least over a partial region. A metal melt is introduced into the mold and applied at least in some regions, whereby the molding material, in particular the blank, is provided with the metal starting material at least in some regions. The metal melt then solidifies and thus forms, for example, a solid or inherently rigid layer as the metal layer, which has, for example, only a small thickness, for example, in the range from about 3 μm to about 2mm to 3mm, and is therefore also referred to as a film.

The metal layer is electrically conductive or conductive and thus forms an electromagnetic shield, by means of which the electric and/or magnetic field is kept away from the component or from the interior of the component, or vice versa, in order to protect the surroundings of the component from the influence of the electric and/or magnetic field, in particular from the component.

By using a metal starting material as the starting material, a particularly advantageous electromagnetic shielding effect or a shielding effect of the layer can be achieved, so that a particularly advantageous electromagnetic compatibility of the component can be achieved. Furthermore, the component can be provided with the shielding in a particularly simple and cost-effective manner, since the molding material or the blank is provided with the layer, while the molding material is in the mold, in particular after its formation.

The mold has, for example, at least cavities, into which the molding compound is introduced, for example, by means of which the molding compound is formed into a blank, wherein a liquid starting material is introduced, in particular injected, into the cavities and is thereby introduced onto the molding compound or onto the blank located in the cavities, in particular toward the molding compound located in the cavities or toward the blank.

The component can be used particularly advantageously as a housing for a current-conducting component, for example an energy store for storing electric current, in particular a high-voltage store, since the weight and the cost of the housing can be kept particularly low by the housing being made, in particular, predominantly of a molded material. Furthermore, since the metal raw material is used as a raw material for implementing electromagnetic shielding, particularly advantageous electromagnetic compatibility of the housing can be achieved in a simple and cost-effective manner. The molding materials which are not metallic in themselves have no or only a very small shielding effect to achieve electromagnetic shielding. However, this shielding can now be realized particularly simply and cost-effectively by using metal starting materials.

The invention is based on the recognition that, at present, high costs are invested in vehicle development in particular in order to reinforce the intrinsically non-metallic housing of the air guiding component subsequently, i.e. after its production, by means of different measures in order to be able to achieve sufficient electromagnetic compatibility. Non-metallic materials such as plastics and molding materials such as those mentioned above do not have any electromagnetic shielding effect at all, but are frequently used for producing housings and housing parts, since such plastics can be shaped particularly advantageously, simply and cost-effectively. Such a housing and housing component can thus be produced, for example, in a cost-effective manner.

However, in order to be able to achieve the desired shielding effect, the respective housing, which is constructed, for example, as a plastic housing, is, after its actual manufacture and is therefore, subsequently equipped with a metallic shielding, which comprises, for example, a 0.2 mm thick aluminum foil, it is furthermore conceivable that the already produced housing is subsequently sprayed with a conductive paint in order to achieve the shielding effect thereby.

The above-mentioned problems and disadvantages are now avoided by means of the method according to the invention, wherein at the same time a particularly advantageous shielding effect can be achieved. Since the molding material or the blank is provided with the metal starting material and thus with the layer in the mold, additional process steps are omitted compared to conventional methods with subsequent processing. The installation space requirement of already produced components having at least molding materials and layers can also be kept particularly low.

For example, the SMC (SMC-Sheet Molding Compound) method is implemented for extruding and shaping a Molding material, so that for example SMC material is used as Molding material. Thus, for example, the components, in particular the housing or housing components, are made of SMC or of SMC material.

For example, In the context of the method according to the invention, an IMC method (IMC-In Mold Coating) is carried out In addition to the SMC method, for example, whereby the molding material introduced into the Mold and located In the Mold is provided with a layer and the molding material is located In the Mold, whereby the molding material is not removed from the Mold after it has been introduced into the Mold and before the molding material is provided with a layer.

In this case, it is to be understood that the metal feedstock has a purity of more than 95%, in particular more than 99%, so that the metal feedstock has exactly metals, the proportion of which in the metal feedstock amounts to more than 95%, in particular more than 99%.

Particularly advantageous properties, in particular a particularly advantageous shielding effect, can be achieved in particular by using tin, in particular pure tin, as pure metal.

In a further embodiment, it is provided that at least auxiliary substances which differ from the metal raw material and which are volatile from the metal raw material during and/or after the solidification of the initially liquid metal raw material are initially introduced into the metal raw material, whereby particularly advantageous properties, in particular flow properties, of the metal raw material can be achieved, so that the initially liquid metal raw material can be processed particularly well, in particular applied to a molding material.

In particular, for example, the proportion of auxiliary material in the mixture is less than 10% by weight or by volume, in particular less than 5% by weight or by volume and preferably less than 3% by weight or by volume, it is particularly conceivable to use only pure metal with auxiliary material incorporated therein as metal raw material, in particular the metal raw material or in particular precisely pure metal is provided with or is incorporated with a low percentage proportion of auxiliary material which, during and/or after solidification, falls off or evaporates from the pure metal.

In particular, it has proven to be advantageous if the layer is composed exclusively of metal raw material, in other words, if the layer is not produced, for example, as an organic layer with a metal filler, but rather if the layer is composed of metal and therefore of an inorganic material, the layer is, for example, a film which is composed of at least substantially uniform layers of metal, in particular tin, the use of tin has proven to be particularly advantageous in combination with SMC material, so that a particularly advantageous shielding effect can be achieved in a particularly simple and therefore cost-effective manner.

In order to be able to carry out the method particularly time-effectively and cost-effectively, at least introduction channels, in particular injection channels, of the die through which the material flows during its introduction are heated to a temperature of more than 200 degrees Celsius, in particular more than 230 degrees Celsius.

Another embodiments are characterized in that the starting material in the liquid state is introduced into the mold at a pressure in the range from 150 bar (including 150 bar) to 1500 bar (including 1500 bar), whereby the method can be carried out particularly time-and therefore cost-effectively.

Tin, for example, has a melting point of 232 degrees celsius. The corresponding SMC material or molding material can have a shape stability of up to 230 degrees celsius. The process parameters for carrying out the method are now set, for example, in such a way that the SMC material or the molding material is not damaged by the introduced melt, which is in particular designed as a tin melt, and the temperatures of the melt, the molding material and the mold prevent an undesirable early solidification of the initially liquid starting material. The melt should be distributed completely in the partial regions or on the surface of the molding material and only solidify thereafter, for example, in order to ensure an at least substantially uniform or uniform thickness of the layer.

In order to achieve particularly advantageous properties of the component, a thermosetting synthetic resin is preferably used as the plastic resin. It has proven particularly advantageous to use unsaturated polyester resins (UP) as synthetic resins.

In order to be able to achieve particularly advantageous properties of the already produced component, in a further embodiments of the invention it is provided that the filler has reinforcing fibers, in particular glass fibers, wherein the proportion of reinforcing fibers in the molding material is, for example, generally in the range from 0% (including 0%) to 40% (including 40%).

Another embodiment is characterized in that the filler comprises at least mineral fillers, in particular chalk and/or stone dust.

In order to be able to achieve particularly advantageous properties of the component, it has proven particularly advantageous if the proportion of mineral filler in the molding compound is generally in the range from 15% (including 15%) to 45% (including 45%). The corresponding reference signs for the individual portions are to be understood in particular as volume percentages or weight percentages.

In a particularly advantageous embodiment of the invention, the molding material is extruded and thereby shaped by means of the mold at a temperature in the range from 100 degrees celsius (including 100 degrees celsius) to 180 degrees celsius (including 180 degrees celsius), in particular in the range from 130 degrees celsius (including 130 degrees celsius) to 160 degrees celsius (including 160 degrees celsius). In other words, the molding material has a temperature in a range from 130 degrees celsius (including 130 degrees celsius) to 160 degrees celsius (including 160 degrees celsius), for example, when the molding material is shaped by means of a mold.

Finally, in order to carry out a particularly cost-effective method, it has proven advantageous to extrude the molding material with the aid of a mold under the pressure prevailing in the mold, in particular in the cavity, and acting on the molding material, which pressure is in the range from 70 bar (including 70 bar) to 160 bar (including 160 bar), and to shape the molding material in this way. Said pressure is also referred to as the process pressure. Preferably, the process pressure, also called the pressing force, is about 100 bar.

The invention also relates to components, in particular for motor vehicles, having at least substrates consisting of a molding material which comprises at least synthetic resins as a matrix and at least fillers embedded in the matrix, and which is extruded by a die and is thus shaped into a blank or a substrate, and having at least layers which are applied at least to some regions of the substrates, consist of a liquid starting material and are produced together with the substrate in the die.

In order to now be able to achieve particularly advantageous properties of the component in a particularly cost-effective manner, it is provided according to the invention that the starting material is a metal starting material from which a uniform layer for electromagnetic shielding is produced. The advantages and advantageous embodiments of the method according to the invention can be seen as advantages and advantageous embodiments of the component according to the invention and vice versa.

fig. 2 shows a schematic cross-sectional view of the component produced.

Detailed Description

In the figures, identical or functionally identical elements are provided with the same reference signs.

Fig. 1 shows a schematic diagram of a method for producing a component 1, which is shown in a schematic sectional view in fig. 2, in particular for a motor vehicle, the component 1 being, for example, a housing or a housing component of a housing, wherein the housing is, for example, a housing of an energy store, the energy store being designed for storing electrical energy or current, wherein the energy store has, for example, a voltage, in particular an operating voltage, of more than 50 volts, in particular more than 60 volts, the energy store is, in particular, designed as a high-voltage store, in particular a high-voltage battery (HV battery), so that the energy store has, for example, a voltage of several hundred volts, in particular an operating voltage, the energy store and thus the component 1, for example, are used in a motor vehicle, which has the energy store and thus the component 1 and at least electric machines in a state in which the motor vehicle has already been produced, for example, at least wheels of the motor vehicle or the motor vehicle as a whole can be driven by means of the electric machines.

As will be explained in more detail below, the method described with reference to fig. 1 makes it possible to achieve particularly advantageous properties of the component 1 as a whole and thus of the housing in a particularly cost-effective manner. In particular, particularly advantageous electromagnetic compatibility can be achieved in a cost-effective manner.

For carrying out the method, a die 2, also referred to as an extrusion die, is used, which has at least two opposing die halves 3 and 4. The mold halves 3 and 4 are movable, in particular translationally, relative to one another and can be moved away from one another and can be moved closer to one another.

In a step S1 of the method, the mold halves 3 and 4 are moved away from one another and are therefore opened, so that the mold 2 is opened as a whole, in a step S1 of the method, in particular during the opening of the mold 2, that is to say during the movement of the mold halves 3 and 4 away from one another or apart from one another, the molding material 5 for producing the component 1 is introduced into the mold 2 and is introduced here between the mold halves 3 and 4, the molding material 5 here has at least , in particular schematically illustrated in fig. 1 and 2, as a matrix, in particular as a plastic matrix, furthermore, the molding material 5 has at least of a filler 7 embedded in the matrix (synthetic resin 6), in particular a vinyl ester or polyester resin, in particular the synthetic resin 6 is a thermosetting synthetic resin, in particular an unsaturated polyester resin (UP) in particular, UP 6, in particular, the filler 7 can have a proportion of reinforcing fibers, in particular glass fibers, and/or a proportion of 15% to 45% in detail, in particular, the filler 7 can be introduced into the mold half before the mold 2 and is heated UP to the mold half, in particular by means of a heating process including heating the mold half before the mold 2 and/or after the mold half is heated, in particular by means of heating to a temperature range of , in particular to 160 degrees celsius, to 160 degrees to preheat the molding material to preheat the temperature, to preheat the mold half to preheat the temperature of the mold half, to preheat the mold 5, to preheat the mold half.

In a second step S2 of the method, the mold 2 is closed in that the mold halves 3 and 4 are moved toward one another or are moved together, the mold 2 is also referred to as a press, which is closed in a second step S2, the mold 2 here has a mold cavity 8 which is formed or delimited in particular by the mold halves 3 and 4 in the closed state of the mold 2 or the mold halves 3 and 4, the molding compound 5 is located in the mold cavity 8 and is shaped by means of this mold cavity, in particular in such a way that the molding compound 5 rests against the mold halves 3 and 4, in particular against the contours of the mold halves 3 and 4, which each delimit the mold cavity 8, the molding compound 5 is pressed by closing the mold halves 3 and 4 or the mold 2, whereby the molding compound 5 is filled with the mold cavity 8, for example in a third step S3, whereby the molding compound 5 is pressed and is shaped 9, which is located in the mold cavity 8.

The molding material 5 or the blank 9 begins to solidify in the closed mold 2, for example under a pressing force of approximately 100 bar present in the cavity 8 and at a temperature of 150 degrees celsius present in the cavity 8. In other words, the molding material 5 is pressed, for example by means of the mold 2, in particular under the pressure prevailing in the cavity 8 and acting on the molding material 5, which pressure ranges from 70 bar (including 70 bar) to 130 bar (including 130 bar), and is thereby shaped. Alternatively or additionally, the molding material 5 in the cavity 8 is solidified in the mold 2 under the pressure.

In a fourth step S4 of the method, at least layers 11 are provided for the molding material 5, in particular the blank 9, at least in the subregion 10, in such a way that the liquid starting material 12 for producing the layers 11 is introduced, in particular injected, into the mold 2, in particular the mold cavity 8, and is applied at least to the subregion 10, in particular at least toward the subregion 10, during the molding material 5, in particular the blank 9, being in the mold 2 and between the mold halves 3 and 4, whereby the starting material 12, which is initially in the liquid state, is applied to the subregion 10 and thus to the molding material 5, in particular the blank 9, before the molding material 5 has completely solidified, the starting material 12 is injected, in particular into the mold 2 and toward the subregion 10, preferably the starting material 12 is injected into the mold 2, in particular the mold cavity 8, under high pressure, for example, the starting material 12 is injected into the mold 2, in particular the mold cavity 8, also referred to as injection pressure, which is greater than 100 bar, preferably the injection pressure comprises 150 bar (including the injection pressure from 1500 bar) to 1500 bar.

Under the injection pressure, the mold 2 opens for example, so that the layer 11 can be distributed particularly advantageously over the molding material 5, in particular over the blank 9, and in this case over the surface 13 of the molding material 5 or of the blank 9, and a particularly advantageous adhesion of the raw material 12 or of the layer 11 to the new or not yet fully cured molding material 5 can be achieved.

In order to now be able to achieve particularly advantageous properties of component 1 in a particularly cost-effective manner, a metal starting material is used as starting material 12, from which layer 11 is produced as an at least substantially homogeneous layer for electromagnetic shielding. In other words, the layer 11 forms an electromagnetic shielding effect, so that a particularly advantageous electromagnetic compatibility of the component 1 can be achieved. For this purpose, the layer 11 is composed of a metallic and electrically conductive or conductive material 12.

In the examples illustrated in fig. 1 and 2, pure metal in the form of pure tin is used as the metal raw material. The tin is injected into the mold 2, in particular into the mold cavity 8, in liquid form and thus as a melt, i.e. as a tin melt, and is injected toward the subregion 10. Here, tin has a melting point of 232 degrees celsius. In particular, such molding materials or SMC materials having a shape stability of up to 230 degrees celsius are used as molding material 5. The process parameters for carrying out the method are now set such that the molding compound 5(SMC material) is not damaged by the injected tin melt and the temperatures of the tin melt, the molding compound 5 and the mold halves 3 and 4 prevent an undesirable premature solidification of the tin and thus of the layer 11. The tin melt is thus distributed at least substantially completely over the surface 13 and only then solidifies. After a fourth step S4, in which the mold 2 is closed and the starting material 12 is injected into the mold cavity 8 as illustrated in fig. 1 by the arrow 14, the mold 2 can be opened by moving the mold halves 3 and 4 apart from one another. The component 1 with the layer 11 can then be removed from the mould 2. The layer 11 is an EMV shield here, which is fixedly anchored to the molding compound 5. The molding compound 5 or the blank 9 forms the base body 15 of the component 1, wherein the base body 15 is provided with the layer 11.

Overall, it can be seen that the molding compound 5 is not removed from the mold 2 after it has been introduced into the mold 2 and before it is injected into the raw material 12, so that the mold 2, also referred to as mold or functional, remains closed after the molding compound 5 has been formed, in particular during a holding time which is dependent in particular on the wall thickness of the molding compound 5 and the reaction temperature.

The raw material 12 is injected into the mold 2, in particular into the mold cavity 8, through at least introduction channels in the form of injection channels 16 of the mold 2, in particular of the mold half 3, in particular depending on the component size, injection channels 16 or injection channels 16 are preferably heated to over 230 degrees celsius, so that the raw material 12 is injected into the mold cavity 8, while the injection channels 16 have a temperature of over 230 degrees celsius, it is conceivable in large components and long flow paths associated therewith to heat the entire mold half 3 or 4 to over 230 degrees celsius, in particular correspondingly to heat the entire mold half 3 or 4, through which the raw material 12 is injected into the mold cavity 8.

The tin melt, which is initially in a liquid state, is injected into the closed mold 2 at a pressure of 150 bar to 1500 bar , the tin melt, which is distributed over the molding material 5 or on the respective side of the molding material 5 and begins to solidify, the temperature of the respective mold half 3 or 4 or of the injection channel 16 can be reduced, so that, for example, the molding material 5 and the initially liquid starting material 12 can be allowed to solidify, the mold 2 is opened immediately thereafter and the component 1 can then be removed.

The connection between the molding material 5 or the blank 9 and the layer 11 embodied as a tin layer is effected, for example, by mechanical clamping on a microscopic level, the tin melt or starting material 12 encounters the not yet completely solidified molding material 5 and cools on its surface 13, since the molding material 5 is not a homogeneous material on a microscopic level, but rather an at least substantially rough surface, in particular in its uncured state, is formed by at least fillers 7, so that the tin melt, which is initially in a liquid state, can be firmly held in this surface 13 or with this surface 13.

If, for example, the molding compound 5 is applied both on the side of the mold half 3 and on the side of the opposite mold half 4, at least injection channels 16 are provided in each case in the mold half 3 and in the mold half 4, respectively, by means of which injection channels the starting material 12 can be injected into the mold cavity 8, for example, if the molding compound 5 is applied both on the side of the mold half 3 and on the side of the opposite mold half 4, then the starting material 12 can be injected into the mold cavity 8.

By means of the electromagnetic shielding caused by the layer 11, the component 1 or its interior can be protected, for example, from electric and/or magnetic fields from the environment and/or the environment can be protected from electric and/or magnetic fields from the component 1. Since the starting material 12 is applied to the surface 13 while the molding compound 5 is located in the mold 2 and without removing the molding compound 5 from the mold 2, the molding compound 5 can be provided with the shielding in a particularly simple and cost-effective manner.
