Definitions

  • the invention relates to a tempering device for a die-cast device, comprising a first component, a second component and at least one fluid channel formed in the first component and / or the second component.
  • the invention further relates to a die casting device.
  • the die casting device is used for die casting.
  • Die casting is preferably used for casting metal, in particular non-ferrous metals or high-strength hot-work steels, or special materials.
  • the molten casting material the melt
  • a casting mold also referred to as a mold insert.
  • 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.
  • the hot chamber method and the cold chamber method can be differentiated.
  • 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.
  • the die casting device and the melt holding furnace 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 tempering device For tempering, in particular for cooling, at least one region of the die casting device, the tempering device is used. This can be used, in particular, to temper a region of the die casting device that can be charged with a casting material. Such a region is, for example, a pouring inlet of the diecasting device, along which or through which the casting material passes in the direction of a diecasting die of the diecasting device. In this case, however, occurs in known from the prior art Temper michsvorraumen the problem that a reliable and uniform temperature of the acted upon with casting material range can not be realized.
  • the tempering or the cooling of the area must be dimensioned such that a reliable cooling is given and at the same time the cooling of a die cast component to be produced in the die casting mold or of the casting material remaining in the area is not impaired by too rapid 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 die-cast component in this way. However, this means that only a comparatively low number of die-cast components can be produced per unit of time.
  • a tool which has a mold shell to be charged with casting material.
  • the tool forms an area of a die casting device to be acted upon by the casting material.
  • thermoelectric device for a diecasting device 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 of time).
  • a tempering device having the features of claim 1. It is provided that this has a first component, a second component and at least one formed in the first component and / or the second component fluid channel, wherein the first component and / or the second component at least one receptacle for an acted upon by a casting material area the Druckgussleaned, in particular a pouring inlet, and wherein the fluid channel opens into at least one heat exchange chamber, the open-edged recess in the first Component is at least partially present and can be closed with the second component.
  • the tempering device for the die casting device is therefore designed at least in two parts. It consists of the first and the second component.

  • the area of the die-cast device which can be charged with casting material is, for example, the casting inlet, which may be in the form of a flow channel or forms it with it.
  • the recording of the tempering device may be formed either by the first component, the second component or by both components together.
  • the tempering device can be acted upon by a tempering fluid, in particular cooling fluid.
  • this tempering fluid flows through the at least one fluid channel, which is formed in the first component and / or the second component.
  • the fluid channel opens, for example, into a fluid connection of the tempering device, via which the tempering fluid can be introduced into or removed from the fluid channel.
  • the heat exchange chamber is provided.
  • the heat exchange chamber is present as an open-edged recess in the first component and can be closed with the aid of the second component. That means that the second component can be arranged on the first component, that the open-edged recess closed and the heat exchange chamber is formed.
  • the open-edged recess is therefore designed to be open toward the second component, wherein the opening of the recess can be covered or closed by the second component. Via the fluid channel, a supply of the heat exchange chamber with tempering fluid is thus ensured. It is particularly advantageous if the heat exchange chamber is formed exclusively by the open-edged recess in the first component, that is, no further depression is provided.
  • the temperature of the region of the die casting device which can be acted upon with casting material can be set at least approximately controlling and / or regulating.
  • at least one temperature sensor can be provided on or in the tempering device, with which its temperature and / or the temperature of the loadable area can be determined at least approximately.
  • the temperature and / or the throughput (volume or mass per unit of time) of the tempering fluid can then be selected or set.
  • the tempering fluid flows through the heat exchange chamber and flows over, for example, a heat transfer surface. If this is assigned to the region which can be acted upon with casting material by thermal or heat transfer, a temperature control of the region takes place in this way.
  • the temperature of the Temper michsfluids is significantly smaller than the temperature of the Temper michsvorraum or the loadable area, so that they can be cooled as quickly as possible and the die-cast component to be manufactured Druckguss Marie can be removed.
  • the heat exchange chamber is thus at least partially formed in the first component, which allows a more reliable loading of the heat transfer surface with the Temper michsfluid and consequently a better cooling characteristics or a faster cooling of the loadable area.
  • the tempering device according to the invention, it is possible to significantly reduce the time required for cooling the die-cast component and thus to achieve an increase in throughput for the die-cast components. For example, in trials with a given diecast component, a reduction in the time required for casting and subsequent cooling from 31 seconds to 21 seconds was realized. Accordingly, a significant increase in the throughput and consequently a reduction in the production costs of the die-cast component can be achieved with the tempering device described here. It should be expressly mentioned at this point that the tempering is intended both for a die casting device, which operates according to the hot chamber method, as well as for one which implements the cold chamber method. Also, any material compositions of the melt can be used.
  • a development of the invention provides that the heat exchange chamber is partially formed by a Fluidleitvertiefung of the second component.
  • the Fluidleitvertiefung of the second component is formed open to the first component. It can therefore together with the open-edged recess of the first component form the heat exchange chamber.
  • the volume of the open-edged recess of the first component is greater than the volume of the Fluidleitvertiefung.
  • the Fluidleitvertiefung has a larger volume than the recess of the first component, that has a greater share of the heat exchange chamber.
  • the heat exchange chamber has a larger cross section than the fluid channel.
  • the cross section lies in a sectional plane which is perpendicular to the direction of the largest extension of the fluid channel. This applies to both the fluid channel and the heat exchange chamber.
  • the heat exchange chamber viewed in cross section, has a larger surface contributing to the temperature control of the die casting device. At the discharge point of the fluid channel in the heat exchange chamber so there should be an expansion. If tempering fluid flows into the heat exchange chamber from the fluid channel, a kind of free jet is formed in the heat exchange chamber.

By this impact, a high heat transfer coefficient is achieved. Only then does the tempering fluid flow out of the heat exchange chamber through the fluid discharge channel.
  • the direction of inflow of the tempering fluid from the fluid supply channel into the heat exchange chamber in its lateral direction should be arranged offset from the heat exchange chamber through a fluid discharge channel by an outflow direction of the tempering fluid.

  • the wall consists of a good heat-conducting material. Accordingly, the pressure zone or the region of the die casting device that can be charged with casting material can be tempered via the heat transfer surface. This applies in particular if the heat transfer surface can be overflowed or flowed with tempering fluid. It is particularly advantageous if the fluid supply channel of the tempering device is directed onto the heat transfer surface, so that tempering fluid flowing through the fluid supply channel into the heat exchange chamber directly overflows or impinges on the heat transfer surface.
  • 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 are assigned to both the pressure zone and the heat transfer surface on opposite sides.
  • a desired heat conduction rate in this can also be achieved via an appropriate choice of wall thickness or specifically adjusted for specific areas.
  • 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.
