  • 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.
  • 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 desired heat conduction rate in this can be achieved by a corresponding choice of the wall thickness or for certain Areas can be targeted.
  • 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.

  • 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.
  • the Fluidleitvorsprung 24 in the heat exchange chamber 62 which is formed by the recess 63 in the first component 21.
  • 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 G maneinlassmaschine 4, consisting of the first component 21 and the second component 22.
  • the first component 21 has the G manmaterialleitfortsatz 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.
  • FIG. 4 shows a sectional view of the G maneinlassiser 4, consisting of the first member 21 and the second member 22.
  • a stream 81 is shown in melt. This is in the region of the pressure zone 60 before.
  • 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. In this case, the heat transfer surface 61 and thus also the pressure zone 60 is cooled by the fluid.
  • 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. 4 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.
  • 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.
  • 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.
  • FIG. 5 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 support surface 83 is also the seal 74th which is arranged between the first component 21 and the second component 22 for sealing the heat exchange chamber 62.
  • a temperature sensor can be arranged to at least approximately determine the temperature of the first component 21 and the casting inlet unit 4.
  • the heat transfer surface 61 has a three-dimensional contour. It lies in the FIG. 4 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, can also be designed in such a way as to ensure the simplest possible manufacturability of the first component 21.
  • FIG. 6 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 is not necessarily, completely filled by the second component 22 be.
  • 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.
  • 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 fluid used for cooling may be either gaseous or liquid.
  • the fluid used for cooling may be either gaseous or liquid.
  • the effectiveness of the temperature control or cooling can be increased.
  • Fluidleitvorsprünge in Provided 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.
