- the produced die-cast component together with the sprue remaining in the sprue area 38 and the casting material 1 remaining in the area of the casting inlet unit 4 can be removed from the die-cast device 1, during a post-processing the sprue is removed from the die-cast component and preferably remelted again.
- FIG. 2 shows a sectional view of the die-cast device 1, showing an arrangement of the die-cast parts 8 to 12 which is present during the casting process. Die casting moldings
- 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 is 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
- each screw 71 has at least one screw 72.
- 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.
- a respective seal 74 is provided which encloses the entire, each associated heat exchange chamber 27, 36, 43, 51 or 62.
- a high fluid pressure can be applied in the heat exchange chambers 27, 36, 43, 51 and 62 without the fluid being able to escape from them inadvertently.
- FIG. 2 again makes it clear that the heat exchange chamber 27 of the die casting molding 8 can only be formed by the fluid guide recess 26 of the second component 14.
- the heat exchange chambers 36, 43, 51 are each through the recesses 35 and 50 of the first components 15 and 19 and a recess 75 of the first th component 17 formed with.
- the die-cast parts 8, 9, 10 and 11 are basically of similar construction, while the die-cast part 12 has a structurally different construction.
- the Fluidleitvorsprung 64 projects into 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.
- FIG. 3 shows a sectional view of the die-cast molding 10, with its first component 17 and the second component 18.
- the die casting molding 10 is formed in the known manner. In this respect, reference is made to the above statements.
- the first component 1 has the recess 75.
- 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 of the tongues 80 accordingly corresponds to one of the flow channels 39.
- FIG. 5 shows the second component 18 of the die-cast molding 10.
- the first component 17 described above is designed as an insert component for the receptacle 42. It becomes clear that that second component 18 in the case of the die-cast molding 10 of the Angusstechnik 3 has a portion of the flow channels 39, so this forms together with the first component 17.
- the embodiment shown here corresponds to the already known, so again reference is made to the above statements.
- FIG. 6 shows a sectional view of the second component 18.
- the fluid inlet port 47 and the fluid outlet port 48 are each formed as a fluid inlet line or fluid outlet line. Again, reference should be made to the above statements.
- the effectiveness of the temperature control or cooling can be increased.
- 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.
