EP2388088A1 - Part of a diecasting die and corresponding diecasting device - Google Patents

Abstract

The parts (8, 9) have heat exchanging chambers (27, 36, 43, 51, 55) permeated by a fluid and formed by two sets of components (13, 14, 15, 16, 17, 18, 19, 20, 21, 22) for controlling temperature of a pressure zone. One set of components has heat transfer surfaces (34, 41) formed integral to a wall of the chambers and thermally connected with the zone. The other set of components has a fluid guiding protrusion (64) protruding into the chambers and fluid guiding recesses (26, 49). The protrusion and/or the recesses form a flow contour surface (65) adapted to the curve of the surfaces. An independent claim is also included for a die casting device comprising a die casting mold part.

Description

The invention relates to a diecasting mold part of a die casting mold, comprising at least one first component comprising a pressure zone, at least one second component and at least one heat exchange chamber through which a fluid flows for the purpose of tempering the pressure zone, wherein the first component comprises at least one wall of the heat exchange chamber , which has pressure zone thermally associated heat transfer surface. The invention further relates to a die casting device.

Such die-casting molds are used for example for Druckgusseinrichtungen for die casting. Die casting is preferably used for casting metal, in particular non-ferrous metals or special materials. In die casting, the molten casting material, the melt, is forced under high pressure at relatively high speed into a casting mold - also referred to as a mold insert. In this case, melt flow rates of 20 to 160 m / s and short shot times for introducing 10 to 100 ms are achieved. The casting mold or die casting consists for example of metal, preferably of a hot-work tool steel. For die casting, the hot chamber method and the cold chamber method can be differentiated. In the former, the die casting device and a melt holding furnace form one unit. The casting unit which supplies the melt to the casting mold is in the melt; With each casting process, a certain volume of the melt is forced into the casting mold. In the cold chamber method On the other hand, the die-casting device and the holding furnace for the melt are arranged separately. Only the amount required for the particular casting is metered into a casting chamber and introduced from there into the casting mold.

The die casting mold consists of at least one die casting molding which has the first and the second component. In this case, the first component has a recess, which represents the heat exchange chamber. The recess or the heat exchange chamber is closed by means of the second component, which is plate-shaped, so as to hold a fluid used for cooling the die-cast molding in the heat exchange chamber. Accordingly, the fluid can be introduced into the heat exchange chamber only via an inlet or an inlet valve and out of the heat exchange chamber through an outlet or an outlet valve.

The first component has the pressure zone, which is pressurized by the melt during the casting process. The pressure zone is part of a wall of the heat exchange chamber. Preferably, the same wall belongs to the heat transfer surface, which is associated with the pressure zone thermally. This means that heat between the pressure zone and the heat transfer surface is transferable and consequently the pressure zone is assigned to the heat transfer surface heat transfer. The second component is preferably provided facing away from the printing zone.

A similar structure is for example from the DE 35 02 895 A1 known. When in the DE 35 02 895 A1 described die-casting mold However, the problem arises that a reliable and uniform temperature of the pressure zone is not feasible. For this reason, a cooling of the die casting molding must be dimensioned so that a reliable cooling is given and at the same time the cooling of a diecast component to be produced is not affected by too fast and / or too uneven cooling. From the boundary conditions of sufficient cooling of the die-cast molding and the most uniform cooling of the die-cast component result in comparatively low cycle times in the production of the die-cast component in order to achieve a good durability of the pressure casting in this way. However, this means that only a comparatively low number of die-cast components can be produced per unit of time.

By contrast, it is the object of the invention to present a die-cast molding which does not have the disadvantages mentioned above, but at the same time enables a good cooling characteristic and a high throughput (die-cast components per unit time).

This is inventively achieved with a die-cast molding with the features of claim 1. It is provided that the second component has at least one projecting into the heat exchange chamber Fluidleitvorsprung and / or open to the first component Fluidleitvertiefung, wherein the Fluidleitvertiefung forms at least a portion of the heat exchange chamber and / or the Fluidleitvorsprung and / or Fluidleitvertiefung one, in particular form / form adapted to the course of the heat transfer surface flow contour surface of the second component. First, therefore, the second component should have the Fluidleitvorsprung or the Fluidleitvertiefung. Both the Fluidleitvorsprung and the Fluidleitvertiefung point in the direction of the first component. This means that the Fluidleitvorsprung protrudes into the heat exchange chamber and the Fluidleitvertiefung is formed open to the first component. In this case, the Fluidleitvertiefung should form at least a portion of the heat exchange chamber, so that the Fluidleitvertiefung can be flowed through by the fluid, which is used for controlling the temperature of the pressure zone or the heat transfer surface.

By introducing the fluid adjusted to a certain temperature into the heat exchange chamber, the temperature of the pressure zone can be set at least approximately controlling and / or regulating. For this purpose, at least one temperature sensor may be provided on or in the die casting molding, with which the temperature of the pressure zone is at least approximately determinable. On the basis of this specific temperature, the temperature and / or the throughput (volume or mass per unit of time) of the fluid can then be selected or set. The fluid flows through the heat exchange chamber and thereby flows over the heat transfer surface. Because this is associated with the thermal or heat transfer the pressure zone, takes place in this way a temperature of the pressure zone.

Usually, the temperature of the fluid is significantly smaller than the temperature of the pressure zone or the die casting molding, so that the die cast component to be produced as possible cools quickly and the Druckgusseinrichtung can be removed. In contrast to known from the prior art die-cast moldings here, therefore, the heat exchange chamber is at least partially formed in the second component, allowing a more reliable loading of the heat transfer surface with the fluid and thus a better cooling characteristics or a faster cooling of the die-cast molding.

Alternatively or additionally, the Fluidleitvorsprung and / or the Fluidleitvertiefung form the flow contour surface. This is provided on the second component. Under flow contour surface is a non-planar surface contour to understand. With the thus present contouring of the second component, the flow of the heat transfer surface with the fluid can be improved or specifically areas of the heat transfer surface can be acted upon with fluid. Also in this way the better cooling characteristics or the faster cooling can be achieved. Preferably, the flow contour surface should be adapted to the course of the heat transfer surface. For example, the flow contour surface and the heat transfer surface may extend parallel to one another at least in regions. In this way, the fluid is guided such that areas of the heat transfer surface are specifically acted upon by the fluid.

For example, this is provided for areas of the heat transfer surface, which correspond to thermally particularly highly stressed areas of the print zone. Alternatively, only the heat transfer surface or the heat transfer surface and the second component may have such a contouring. Preferably, the heat transfer surface and / or the second component are contoured such that the most uniform possible cooling of the diecast component to be produced is achieved. In this way, stresses in the material of the die-cast component are avoided, thus achieving high stability.

It should be expressly mentioned at this point that the die-cast molding can be used both for the hot chamber method and for the cold chamber method and for any material compositions of the melt.

A development of the invention provides that the Fluidleitvertiefung at least for the most part, in particular completely, forms the heat exchange chamber. It can therefore be provided that, in addition to the Fluidleitvertiefung another depression is present, for example in the first component, which forms the heat exchange chamber together with the Fluidleitvertiefung. However, the volume of the Fluidleitvertiefung should be greater than the volume of the further depression. It is particularly advantageous if the heat exchange chamber is formed exclusively by the Fluidleitvertiefung, so no further depression is provided.

A preferred embodiment provides that the Fluidleitvertiefung is trough-shaped formed in the second component. The Fluidleitvertiefung is therefore a recess which is so enclosed by the second component, that only one opening is provided so that the Fluidleitvertiefung is open to the first component. In particular, the Fluidleitvertiefung should be limited at least laterally from the second component. In such an embodiment, for example, one connected to the second component or connectable - for example by means of a screw - third component forming the bottom of Fluidleitvertiefung.

A further embodiment of the invention provides that the first component is designed lid-like or flat. Under cover-like is an embodiment of the first component to understand, in which this - seen in cross-section - in its edge regions the second component further counteracted as in a central region. This can be realized for example by a curvature of the first component or by providing an edge web. Alternatively, however, the first component may also be formed flat, wherein it has a planar course seen in cross-section, so that a distance to the second component is substantially constant.

According to a development of the invention it is provided that a recess of the first component forms the heat exchange chamber at least partially with. Such an embodiment has already been indicated above. The heat exchange chamber may be formed entirely by the recess of the first component, in which case the fluid-conducting projection of the second component protrudes into the recess. Alternatively, both the recess of the first component and the Fluidleitvertiefung of the second component may be provided and form the heat exchange chamber together. Preferably, the volume of the Fluidleitvertiefung is greater than that of the recess.

An advantageous development provides that the flow contour surface has at least one of the Fluidleitvorsprung and / or the Fluidleitvertiefung formed with convex and / or concave area. The flow contour surface can in principle arbitrary be shaped. However, it preferably has convexly or concavely formed regions in which the flow contour surface runs steadily, that is, has no jumps or shoulders. If a plurality of convex and / or concave areas are provided, the transition between these preferably also runs continuously. Due to the continuous flow contour surface, the heat exchange chamber can be designed to be flow-favorable, that is, to oppose the fluid flowing through it with a comparatively low flow resistance. Furthermore, the occurrence of vortices and / or backflows is reduced, so that a reliable overflow of the heat transfer surface is given to the fluid.

The convex or concave regions can be formed at least by the fluid-conducting projection and / or the fluid-conducting recess. This means that the Fluidleitvorsprung or the Fluidleitvertiefung at least partially have a convex and / or concave surface. The Fluidleitvorsprung or the Fluidleitvertiefung can also be used as so-called turbulators, to increase in this way the heat transfer from the heat transfer surface to the fluid.

A further embodiment of the invention provides that the contour of the heat transfer surface is at least partially approximated to one, in particular three-dimensional contour of the print zone or corresponds to it. This can be achieved for example by a uniform wall thickness of the wall, which both the pressure zone and the heat transfer surface on each opposite Pages are assigned. Alternatively, however, a desired heat conduction rate in this can also be achieved via an appropriate choice of wall thickness or specifically adjusted for specific areas. For example, it can be provided that the wall thickness of the wall decreases in the direction of flow of the fluid, since the fluid warms up when flowing through and thus decreases its cooling effect on the heat transfer surface or the pressure zone. To compensate for this, it may be necessary to increase the thermal conductivity of the wall, which is usually achieved by a smaller wall thickness.

In a preferred embodiment, it is provided that the flow contour surface extends to the heat transfer surface in such a way that an approximately uniformly large flow cross section for the fluid is present at least zonally over the flow path of the fluid in the heat exchange chamber. Accordingly, the flow contour surface extends at least partially substantially parallel to the heat transfer surface. This achieves the constant flow cross section for the fluid. Such an embodiment has the advantage that the occurrence of vortices and / or backflows is reduced, which preferably occur in areas in which the flow cross section for the fluid changes too much or too fast.

A development of the invention provides that the heat exchange chamber is fluid-connected to at least one, in particular designed as a fluid line fluid connection. In order to supply and / or remove fluid from the heat exchange chamber, the Fluid connection provided, with which the heat exchange chamber is fluidly connected. Preferably, the heat exchange chamber associated with two fluid ports, wherein the fluid of the heat exchange chamber can be supplied through one of the fluid ports and discharged through the other from the heat exchange chamber. The fluid connections can be formed at least in regions as - for example, pipe-like design - fluid line.

An advantageous embodiment of the invention provides that the fluid line is provided at least partially in the first component and / or the second component. The fluid line therefore runs partially through the first and / or second component. For example, the fluid line is provided as a bore and thus forms a Fluidzuführbohrung or a Fluidabführbohrung. If a plurality of fluid ports or fluid conduits mouth into the heat exchange chamber, they are preferably arranged clearly spaced from one another, in particular if fluid is supplied to the heat exchange chamber by means of one fluid port and fluid is removed by means of the other fluid port. In this case, an arrangement of the orifices of the fluid connections or fluid lines of the heat exchange chamber is preferred on opposite sides of the same in the direction of flow.

A further embodiment of the invention provides that the first component or the second component has a receptacle, in which the second or the first component at least partially, in particular completely, can be used. After inserting the first or of the second component in the receptacle is preferably encompassed by the respective other component, that it is fixed at least in the lateral direction, so no slippage of the one component with respect to the other component in this direction is possible. For supporting the one component in the vertical direction may be provided on the other component, a support surface in the region of the receptacle. This support surface is preferably formed as a support web, which extends in an outer region of the receptacle to further areas of the exception around. The bearing surface can cooperate to achieve a sealing effect between the one and the other component with a mating surface of a component.

According to a development of the invention, it is provided that the pressure zone of the first component delimits at least a part of a casting mold for a die-cast component, a sprue area and / or a pouring inlet. The mold is provided for forming the die-cast component. In it, therefore, the melt is introduced during the casting process and then removed the die-cast component from her. For this purpose, the pressure casting mold essentially forms at least one region of the die-cast component as a negative. The pressure zone is now intended to limit the mold at least partially. Accordingly, the pressure zone is subjected directly to the melt when carrying out the casting process and is therefore exposed to both high temperatures and strong temperature changes. Alternatively or additionally, it can of course also be provided that the pressure zone of the first component of the sprue area or the Casting inlet limited. The latter is often referred to as a die or as a countermark.

A preferred embodiment provides that a pressure range of the second component mitbegrenzt the casting mold, the sprue area and / or the pouring inlet. In addition to the pressure zone of the first component, therefore, the pressure region of the second component is provided adjacent to the casting mold, so that the pressure zone and the pressure region at least partially define the casting mold together. It can therefore be provided that both the first component and the second component are subjected to the melt during the casting process. Alternatively or additionally, it may also be provided that the pressure range of the second component limits the sprue area or the pouring inlet.

An advantageous embodiment of the invention provides that the heat exchange chamber is adapted in shape to the course of at least one of the casting mold, the gate region and / or the pouring inlet associated flow channel. Thus, the shape is particularly adapted to the peripheral contour of the print zone, in which a particularly good or uniform cooling is to be achieved. By way of example, the heat exchange chamber may have at least one bulge in the region of the heat transfer surface which is thermally associated with the flow channel or the corresponding region of the casting mold, the sprue region and / or the pouring inlet. This is especially true in plan view, so that from this perspective, for example, a coastal-like course can be present with the at least one bulge or indentation. To this Way can also be achieved in the region of the flow channel excellent cooling effect or cooling characteristics.

A development of the invention provides that the first component is detachably connected to the second component, in particular by means of a screw connection. It is provided that the first component is formed separately from the second component. Subsequently, the at least two components are assembled to the die-cast molding and thereby releasably connected to each other, wherein the heat exchange chamber is formed. The detachable connection can in principle be made arbitrarily. However, a screw connection with at least one screw or a threaded bolt is preferred.

According to a development of the invention, it is provided that the first and / or the second component have at least one sensor receptacle for a temperature sensor. The temperature sensor serves to at least approximately determine the temperature of the first or of the second component. On the basis of the specific temperature, a temperature control of the fluid or an adjustment of a fluid flow rate can be controlled and / or regulated. Preferably, the sensor receptacle is arranged such that the temperature sensor can at least approximately detect the temperature of the pressure zone or of the pressure region of the first or of the second component.

A further embodiment of the invention provides between the first and the second component a sealing the heat exchange chamber Seal in front. In order to prevent an unforeseen leakage of the fluid from the heat exchange chamber, this is associated with the seal. The seal can be designed for example as an O-ring and embrace the heat exchange chamber in the circumferential direction substantially. An exchange of the fluid located in the heat exchange chamber is of course also possible by means of the fluid connection or the fluid line.

The invention further relates to a die casting device, comprising at least one die casting molding, in particular according to the preceding embodiments, wherein the die casting molding is part of a die and at least one first component, at least one second component and at least one of the components formed by a fluid durchströmbare heat exchange chamber for controlling the temperature of the pressure zone, wherein the first component has a at least one wall of the heat exchange chamber belonging, the pressure zone thermally associated heat transfer surface. It is provided that the second component has at least one projecting into the heat exchange chamber Fluidleitvorsprung and / or open to the first component Fluidleitvertiefung, wherein the Fluidleitvertiefung forms at least a portion of the heat exchange chamber and / or the Fluidleitvorsprung and / or Fluidleitvertiefung one, in particular form / form adapted to the course of the heat transfer surface flow contour surface of the second component. The die-casting device is, for example, a die-casting machine and is accordingly designed for the production of die-cast components. It has, among other well-known elements on at least one die-cast molding, which according to the above statements, education or training.

An advantageous embodiment of the invention provides that in each case at least one die casting mold form a casting mold unit, a runner unit and / or a casting inlet unit of the die casting device, the casting mold unit having a casting mold, the runner unit having a casting area and the casting inlet unit having a casting inlet. In this case, the casting mold, the sprue area and the pouring inlet are respectively delimited, at least in regions, by the pressure zones of the first components of the die cast molding of the die casting mold. In the casting mold unit, the casting mold is provided, into which the melt is introduced and from which subsequently the die cast component can be removed. The feeding of the melt takes place via the gate unit and / or the pouring inlet unit. Usually, the mold unit and the Angusseinheit consist of at least two die-cast moldings, while the Gießeinlasseinheit only has at least one die-cast molding.

A development of the invention provides that the casting mold, the sprue area and / or pouring inlet are fluidly connected to each other for flowing through with a casting material. The liquid or molten casting material is also referred to as a melt. As already stated above, the supply of the casting material to the casting mold takes place via the sprue area or the casting inlet. Accordingly, the fluid connection between the mold, the gate area and the pouring inlet must be provided. The casting mold, the sprue area and the pouring inlet thus represent casting areas, which can be flowed through by the melt or the casting material.

According to a development of the invention, it is provided that the heat exchange chambers of the casting mold unit, the runner unit and / or the pouring inlet unit, in particular via at least one passage or at least one line, are fluidly connected to each other for flowing through with the fluid. Both the mold unit, the Angusseinheit, and the Gießeinlasseinheit can each consist of a die-casting mold, which in turn has at least two die-cast moldings. Accordingly, the mold unit, the gate unit and the pouring inlet unit each have a heat exchange chamber. These heat exchange chambers should be connected to each other in such a way that they can be flowed through jointly by the fluid.

In this way, it may be provided, for example, that the heat exchange chamber of the mold unit have a fluid supply port for supplying the fluid and the pouring inlet unit have a fluid outlet port for removing the fluid from the die casting device. Accordingly, the fluid supplied through the fluid supply port first flows through the casting mold unit, then the gate unit and subsequently the pouring inlet unit, and then exits the die casting device through the fluid outlet port. Alternatively, it can of course be provided that the heat exchange chambers of the mold unit, the Angusseinheit and / or the Gießeinlasseinheit each have separate fluid connections. Finally, it is provided that the heat exchange chambers of the casting mold unit, the runner unit and / or the pouring inlet unit are connected to at least one common fluid connection. In this way, it is possible, as already stated above, to simultaneously supply the fluid to both the mold unit, the gate unit and the pouring inlet unit, without having to provide separate fluid connections. In this way, the design effort for the die-cast device or the respective die-cast molding can be reduced.

Likewise, the mold unit, Angusseinheit and Gießeinlasseinheit be individually controlled or controlled.

The FIG. 1 shows a die casting device 1, for example, a die casting machine or a part of such. The die casting device 1 is used to produce one or more die-cast components (not shown). It has a casting mold unit 2, a runner unit 3 and a pouring inlet unit 4. The casting mold unit 2 consists of a first die casting mold 5, the runner unit 3 of a second die casting mold 6 and the casting inlet unit 4 of a third die casting mold 7. The first die casting mold 5 settles two die-cast mold parts 8 and 9 and the second die-casting mold of die-cast moldings 10 and 11 together. The third die casting mold 7 consists of a die-cast molding 12. The die-cast molding 8 has a first component 13 and a second component 14. Similarly, the die casting mold parts 9 to 12 first components 15, 17, 19 and 21 and second components 16, 18, 20 and 22 are assigned.

In the following, the die casting mold parts 8 and 9 of the casting mold unit 2 will first be discussed in greater detail. The casting mold unit 2 has a casting mold 23 which is present at least in regions between pressure zones 24 and 25 of the first components 13 and 15. The casting mold 23 essentially has a shape which represents a negative of a die-cast component to be produced. In a casting process performed with the die casting device 1 casting material or melt is thus introduced into the casting mold 23 between the pressure zones 24 and 25, and after cooling and solidification of the melt, the die casting component is removed from the casting mold 23. For this purpose, the die casting molding 8 and / or the die casting molding 9 in the vertical direction of the other die casting molding 9 or 8 fortverlagerbar. Accordingly, a corresponding displacement device is provided for this purpose.

Basically, the die-cast moldings 8 and 9 have a similar structure, so that at first only the diecasting mold part 8 is described and only the differences from the die cast mold part 9 are pointed out. The second component 14 of the die-cast molding 8 has a Fluidleitvertiefung 26, which forms a heat exchange chamber 27 of the die-cast molding 8 completely. For this reason, the first component 13 is designed to be flat or plate-shaped and is thus arranged on the second component 14. that it closes the heat exchange chamber 27 and the Fluidleitvertiefung 26. The Fluidleitvertiefung 26 is formed like a trough in the second component 14. This means that the second component 14 closes the fluid-conducting recess 26 with the exception of the opening 28 facing the first component 13.

For receiving the first component 13, the second component 14 has a receptacle 29, which is designed such that the second component 14 can completely accommodate the first component 13. In this case, the pressure zone 24 of the first component 13 is substantially on a plane with sealing surfaces 30, which cooperate with corresponding sealing surfaces (not shown here) of the die-cast molding 9 to seal the mold 23 during the casting against an environment of the die-casting device 1. In the receptacle 29, a support surface 31 is provided, which is designed as a circumferential support web and a support of the first component 13 in the receptacle 29 is used.

Two fluid inlet ports 32 and two fluid outlet ports 33 open into the heat exchange chamber 27, of which only one is shown visibly. The fluid inlet ports 32 and the fluid outlet ports 33 as fluid inlet passages and fluid outlet passages, respectively, pass through the walls bounding the heat exchange chamber 27 to allow the heat exchange chamber 27 to be supplied with a fluid. In this case, the fluid can be supplied through the fluid inlet ports 32 of the heat exchange chamber 27 and discharged through the Fluidauslassanschlüsse 33. The assignment shown here is to be understood as purely exemplary. Thus, the fluid inlet ports 32 and the fluid outlet ports 33 are interchanged, respectively, so that the heat exchange chamber 27 can be traversed in different directions by the fluid. Opposite of the pressure zone 24, a heat transfer surface 34 is arranged, which is overflowed with the present in the heat exchange chamber 27 fluid. The heat transfer surface 34 in this case belongs to a wall of the heat exchange chamber 27, preferably the same wall as the pressure zone 24.

The die casting mold part 8 arranged directly opposite the die casting molding 8 essentially differs from the former in that here the first component 15 has a depression 35 which at least partially forms a heat exchange chamber 36 of the die casting molding 9. Furthermore, the second component 16 of the die-cast molding 9 has only one fluid inlet port 37.

The statements made above for the die cast parts 8 and 9 can essentially be transferred to the die cast parts 10 and 11. Nevertheless, it will be briefly discussed below. The die-cast moldings 10 and 11 are part of the gating unit 3, in which there is a sprue area 38 or is delimited by the first components 17 and 19. The sprue area 38 is present in flow channels 39 incorporated in the first components 17 and 19 (here indicated only for the first component 17). In the flow channels 39 is also a pressure zone 40 of the Angusseinheit 3 ago.

Opposite the pressure zone 40, a heat transfer surface 41 is provided on the first component 17. Is the first component 17 arranged in a receptacle 42 provided for this purpose of the second component 18, the heat transfer surface 41 together with the second component 18 defines a heat exchange chamber 43 of the die-cast molding 10. In the receptacle 42, a support surface 44 is provided, which is designed as a peripheral support web. The receptacle 42 is designed such that the second component 18 can completely accommodate the first component 17, so that sealing surfaces 45 of the first component 17 are aligned with sealing surfaces 46 of the second component 18 and with sealing surfaces of the first component 19 and the second component, not shown here 20 cooperate for sealing the sprue area 38 with respect to an environment of the die casting device 1.

In the second component 18, at least one fluid inlet connection 47 and one fluid outlet connection 48 are provided, which open into the heat exchange chamber 43. The heat exchange chamber 43 is also formed here as a Fluidleitvertiefung 49.

The directly opposite the die casting molding 10 provided die-cast molding 11 is constructed analogously to this. In this respect, statements made for the diecast part 10 are readily transferable to the diecast part 11 and vice versa. The FIG. 1 shows that the first component 19 of the die-cast molding 11 has a recess 50. If the first component 19 is arranged in the second component 20, then this recess 50 serves to form a heat exchange chamber 51. The second component 20 has, analogously to the second component 18 of the die-cast molding 10, in each case a fluid inlet port 52 and a fluid outlet port 53.

The FIG. 1 The casting inlet unit 4 is associated with a cooling ring 54, which has a heat exchange chamber 55 which is closable with a closure plate 56. The cooling ring 24 in this case has a central opening 57 into which a Gießmaterialleitfortsatz 58 of the first member 21 of the die-cast molding 12 engages. On the Gießmaterialleitfortsatz 58, a flow channel is formed as a pouring inlet 59, which also extends over other areas of the first member 21 up to the Angusseinheit 3. Along this pouring inlet 59, molten casting material (melt) can flow to pass through the gate unit 3 into the mold unit 2. In the flow channel 59 is so far also a pressure zone 60 before. This is relative to a wall of the first component 21, a heat transfer surface 61 (not visible here) opposite. This heat transfer surface 61 is present in a heat exchange chamber 62, which is formed by a recess 63 of the first component 21.

The heat exchange chamber 62 is opened in the direction of the second component 22. The second component 22 serves to close the heat exchange chamber 62 or the recess 63. The second component 22 has a Fluidleitvorsprung 64, which projects into the heat exchange chamber 62. The fluid guide projection 64 forms a flow contour surface 65 of the second component 22. The flow contour surface 65 is a non-planar surface contour and has a concave region 66. The concave portion 66 is formed by the Fluidleitvorsprung 64 with. To the heat exchange chamber 62 of the die-cast molding 12 are both a fluid inlet port 67 and a fluid outlet port 68 are connected. This is however in the FIG. 1 not visible.

The in the FIG. 1 illustrated die casting device 1 is used to produce die-cast components of casting material, which is in the form of the melt. To produce the die-cast component, the die-cast parts 8 and 10 and the die-cast parts 9 and 11 are moved towards one another so that the casting mold 23 or the sprue area 38 is sealed. Subsequently, through the opening 57 of the pouring inlet unit 4, the pressurized melt is fed, which runs along the pouring inlet 59 in the direction of the gating unit 3 and flows into its sprue area 38 or the flow channels 39. The flow channels 39 provide for a fanning out of the stream of melt, so that the casting mold 23 can be fed to the melt in different positions as seen in the lateral direction. The casting inlet unit 4 is supplied with melt until the casting mold 23 is filled.

Subsequently, the melt is cooled, for which purpose fluid is introduced into the heat exchange chambers 27, 36, 43, 51, 55 and 62. The temperature of the fluid or its mass flow is selected such that the best possible cooling characteristic of the die-cast component is present. For this purpose, it is particularly necessary to cool this as evenly as possible in order to ensure a sufficiently high stability of the die-cast component. Another goal is to cool as quickly as possible in order to achieve a high throughput of the die cast components and thus lower production costs.

After solidification or cooling of the melt, the die-cast mold parts 8 and 10 and the die-cast mold parts 9 and 11 are displaced away from each other, so that the casting mold 23 and the sprue area 38 are released. Likewise, the cooling ring 54 is removed from the casting inlet unit 4. Subsequently, the produced die cast component together with the sprue remaining in the sprue area 38 and the casting material of the die casting device 1 remaining in the area of the casting inlet unit 4 can be removed. As part of a post-processing of the sprue is removed from the die-cast component and preferably remelted.

The FIG. 2 shows a sectional view of the die-cast device 1, wherein an arrangement of the die-cast moldings 8 to 12 is shown, which is present during the casting process. The die-cast moldings 8 and 9 and the die-cast moldings 10 and 11 are therefore in each case in a sealing manner against one another. It is clear that the casting mold 23 is not limited only by the pressure zone 24 of the die casting 8 and an unspecified pressure zone of the die casting 9, but that the second components 14 and 16 each have a pressure range 69 and 70, which define the casting mold 23 , In this case, the pressure region 69 terminates substantially flush with the pressure zone 24 and the pressure region 70 with the pressure zone 25 of the first component 15 of the die-cast molding 9. It can again be seen that the first components 13 and 15 are each completely accommodated in the second components 14 and 16, for which purpose the receptacle 29 is provided in the case of the die-cast molding 8.

It can also be seen that the components 13 and 14 and 15 and 16, as well as 17 and 18 and 19 and 20 are each held together by means of a screw 71. Each screw 71 has at least one screw 72. It can also be seen that in each case a sensor receptacle 73 is provided in the second components 14 and 16, in which a temperature sensor, not shown here, can be arranged. By means of this temperature sensor, the temperature of the second components 14 and 16 or at least approximately the temperature of the pressure zones 24 and 25 can be determined. On the basis of this specific temperature, the temperature of the fluid or its mass flow is then adjusted in a controlling and / or regulating manner. In this way, the present in the die casting device 1 melt can be cooled quickly and selectively to a certain temperature. Between the components 13 and 14, 15 and 16, 17 and 18, 19 and 20 and 21 and 22, a respective seal 74 is provided, which encloses the entire, respectively associated heat exchange chamber 27, 36, 43, 51 or 62. Thus, in the heat exchange chambers 27, 36, 43, 51 and 62 each have a high fluid pressure can be applied without the fluid can escape from them unintentionally.

The FIG. 2 makes it clear again that the heat exchange chamber 27 of the die-cast molding 8 can be formed only by the Fluidleitvertiefung 26 of the second component 14. In contrast, the heat exchange chambers 36, 43 are each formed by the recesses 35 and 50 of the first components 15 and 19 and a recess 75 of the first component 17 with. It is nevertheless clear that the die-cast moldings 8, 9, 10 and 11 basically have a similar structure are while the die-cast part 12 shows a structurally different structure. In this protrudes, as already described above, the Fluidleitvorsprung 24 in the heat exchange chamber 62, which is formed by the recess 63 in the first component 21. It is also provided that the contour of the heat transfer surface 61 is adapted to the contour of the print zone 60 at least partially. In part, the flow contour surface extends in such a way to the heat transfer surface 61, that at least zonal an approximately constant large flow cross section for the fluid is formed.

The FIG. 3 shows the die-cast molding 8 in a sectional view. It is different from the in FIG. 2 illustrated die casting molding 8, the heat exchange chamber 27 formed both by the Fluidleitvertiefung 26 of the second member 14 and a recess 76 of the first member 13 together. The recess 76 and the Fluidleitvertiefung 26 are thus in fluid communication with each other to form the heat exchange chamber 27. In this case, they have the same dimensions in the lateral direction, so that side walls of the Fluidleitvertiefung 26 and the recess 76 are aligned. A casting mold receptacle 77, which is delimited by the pressure zone 24 and the pressure zone 69, can also be seen. In this mold receptacle 77, the die casting molding 9 is at least partially received to carry out the casting process to form the mold 23.

In order to allow filling of the casting mold 23, a feed 78 is formed in the second component 14. About this inlet 78 is a flow connection to the flow channels 39 and can be produced in the sprue area 38 of the gating unit 3. In this case, the inlet 78 is also present when the sealing surface 30 cooperates with a corresponding sealing surface of the die-cast molding 9 in such a way that the casting mold 23 is sealed by an environment of the die-casting device 1.

The FIG. 4 shows the first component 13. It is clear that the recess 76 is like a trough in this.

The FIG. 5 shows the second component 14. It can be seen that the Fluidleitvertiefung 26 has smaller dimensions in the lateral direction than the receptacle 29 to form the support surface 31. In the FIGS. 4 and 5 bores 79 can be seen, which are provided for receiving the screws 72. Accordingly, it becomes clear that six screws 72 are provided for fastening the first component 13 to the second component 14.

The FIG. 6 shows a sectional view of the die-cast molding 10, with its first component 17 and the second component 18. The die-cast molding 10 is formed in the known manner. In this respect, reference is made to the above statements.

The FIG. 7 shows the first component 17 of the die-cast molding 10 in a view from below. It therefore becomes clear that the first component 17 has the recess 75. In this case, this recess 75 tongues 80 which extend substantially below the flow channels 39 in order to sufficiently cool the pressure zone 40 located in these, by the heat transfer surface 41 is also present in this area and can be overflowed by fluid. each The tongues 80 accordingly correspond to one of the flow channels 39.

The FIG. 8 shows the second component 18 of the die-cast molding 10. The first component 17 described above is formed as an insert member for the receptacle 42. It becomes clear that, in the case of the die-cast molding 10 of the gating unit 3, the second component 18 has a region of the flow channels 39, that is to say forms it together with the first component 17. The embodiment shown here corresponds to the already known, so again reference is made to the above statements.

The FIG. 9 shows a sectional view of the second component 18. In addition to that described above, it is clear that the fluid inlet port 47 and the fluid outlet port 48 are each formed as a fluid inlet pipe or fluid outlet. Again, reference should be made to the above statements.

The FIG. 10 shows the Gießeinlasseinheit 4, consisting of the first component 21 and the second component 22. The first component 21 has the Gießmaterialleitfortsatz 58, in which the casting inlet 59 and the pressure zone 60 regions present. However, both continue in a bottom region of the first component 21 in the direction of the gating unit 3.

The FIG. 11 shows a sectional view of the Gießeinlasseinheit 4, consisting of the first member 21 and the second member 22. In order to illustrate the structure of the Gießeinlässeinheit 4, a stream 81 is shown in melt. This is in the area of the pressure zone 60 ago. Relative to the wall assigned to the pressure area 60, the heat transfer area 61 is located opposite this wall. This limits the heat exchange chamber 62, which corresponds to the fluid inlet port 67 and the fluid outlet port 68. Fluid flowing in through the fluid inlet connection 67 thus flows through the heat exchange chamber 62 as far as the fluid outlet connection 68. The heat transfer surface 61 and thus also the pressure zone 60 are cooled by the fluid.

It is indicated here that one of the seals 74 is also provided between the first component 21 and the second component 22. The fluid inlet connection 67 is designed such that fluid flowing into it from the heat exchange chamber 62 initially strikes a deflection region 82 which is formed by the wall of the first component 21 at the highest point of the heat exchange chamber 62. The deflection region 82 causes a deflection of the fluid so that it flows in the direction of the fluid outlet connection 68.

The FIG. 11 makes it clear that the flow contour surface 65 of the second component extends to the heat transfer surface 61 such that the fluid is given a substantially constant flow cross section. For this purpose, the flow contour surface 65 runs at least in regions parallel to the heat transfer surface 61. The second component 22 is arranged on the first component 21 in such a way that it closes the heat exchange chamber 62. For this purpose, the heat exchange chamber 62 is provided on the side facing away from the pressure zone 60 of the first component 21 with an opening and the second component 22 for closing the same arranged in this opening.

The FIG. 12 shows a view of the first component 21 from below. Because the second component 22 is not shown, a view through the opening into the heat exchange chamber 62 is possible. It becomes clear that here the first component 21 provides a bearing surface 83 for the second component 22. In the bearing surface 83 is also the seal 74, which is arranged for sealing the heat exchange chamber 62 between the first component 21 and the second component 22.

In addition to the holes 79 which are arranged for producing the screw 71 between the components 21 and 22, shows FIG. 12 also a further sensor receptacle 73. In this, a temperature sensor can be arranged to at least approximately determine the temperature of the first component 21 and the casting inlet unit 4.

In the FIG. 12 It can also be seen that the heat transfer surface 61 has a three-dimensional contour. It lies in the FIG. 11 shown concave profile of the heat transfer surface 61 only in a vertical sectional area (starting from the line 84) before. In the lateral direction, which is perpendicular to the sectional plane, a course of the heat transfer surface 61 deviating from this concave profile may be present. The heat transfer surface 61 is preferably contoured such that the most uniform possible cooling of the melt takes place through the fluid in the heat exchange chamber 62. In principle, however, the heat transfer surface 61 can be configured as desired and, for example, also be designed in such a way that to ensure the simplest possible manufacturability of the first component 21.

The FIG. 13 shows a view of the first component 21 from below, wherein the opening of the heat exchange chamber 62 (not visible here) is closed with the second component 22. A receptacle 85, which has the first component 21 for the second component 22, may, but need not, be completely filled by the second component 22. In the illustrated example, the second component 22 in the region of a portion of the holes 79 recesses, so that the receptacle 85 is not completely filled by the second component 22. However, it is advantageous if the receptacle 85 is configured in principle such that the second component 22 is completely received in the receptacle 85 at least in the vertical direction. This means that a depth of the receptacle 85 substantially corresponds to a wall thickness of the second component 22 in the region of the support surface 83, so that the components 21 and 22 form with their bottom surfaces a substantially planar surface.

The FIG. 14 shows a view of the die casting device 1, wherein only the second component 14 and the second component 18 are shown together with the casting inlet unit 4. Here again it becomes clear that the pouring inlet 59 of the pouring inlet unit 4 is in flow communication with a region of the flow channels 39 formed by the second component 18. The same applies to the flow channels 39 opposite the flow direction and the inlet 78 of the second component 14. The illustrated components 14 and 18 as well as the casting inlet unit 4 substantially correspond to FIG known versions, so that reference is made to the above statements.

The FIG. 15 shows the from the FIG. 14 known arrangement, wherein in the second component 14 now the first component 13 and in the second component 18, the first component 17 is present. Thus, the die-cast moldings 8 and 10 are substantially completely present. Thus, there is a flow connection between the Gießeinlasseinheit 4 and the pouring inlet 59 and the mold 23, because the components 17 and 18, the flow channels 39 together form, thus establishing a connection between the pouring inlet 59 and the inlet 78 and thus to the mold 23. Again, reference is made to the above statements for a more detailed description of the individual elements.

It should be pointed out again that at least the die-cast moldings 8, 9, 10 and 11 are each constructed similarly, so that the properties held in each case above are largely transferable to any other of these elements.

With the pressure casting device 1 or the die casting parts 8 to 12 presented here, a good flow through the heat exchange chambers 27, 36, 43, 51 and 62 and thus a high heat exchange or good cooling of the casting mold 23, the sprue region 38 and the casting inlet 59 can be achieved. In this way, the solidification time of the die-cast component to be produced can be reduced and at the same time a homogeneous cooling of the same can be achieved. Accordingly, at all times in the areas to be cooled there is a substantially homogeneous one Temperature picture before. In particular in the area of the casting mold 23, an FEM process is used for the design of the die-cast moldings 8 and 9.

The fluid used for cooling may be either gaseous or liquid. By targeted design of the heat exchange chambers 27, 36, 51, 55 and 62, the effectiveness of the temperature control or cooling can be increased. For this purpose, for example, in the die-cast parts 8, 9, 10 and 11 Fluidleitvorsprünge provided in the sense of the die-cast molding 12, which protrude into the respective heat exchange chamber 27, 36, 43, 51 or 55. Such Fluidleitvorsprünge serve insofar as turbulators, for example, to generate turbulence and thus to increase the heat transfer.
