Definitions

  • the invention relates to a casting mold comprising at least two molded parts which form the cavity for receiving the casting material.
  • Molds of various kinds are known; such is z. B. the use of permanent molds in injection molding, die casting, chill casting and low pressure casting known.
  • it is known to cool the mold.
  • the mold For this purpose, it is particularly known to pass through the mold with individual channels, is guided by the cooling liquid, in particular water or oil. Because only when the casting is completely solidified, the mold can be opened, and the casting can be removed. Cooling of the casting mold from the rear side of the cavity is also known in this connection in that bores are arranged in the casting mold in the direction of the cavity, wherein lances can be introduced into the bores, water or similar fluids being introduced into the passages by means of the lances be injected to cool the mold.
  • the mold itself usually has a high mass on the side facing away from the cavity and has a high inertia in relation to the cooling. That is, if the mold is cooled in the region of the cavity on the back, so this requires a lot of energy. This would be without ensuring that the cavity through its cooling over their surface has a predeterminable temperature distribution. In this regard, it should be remembered that castings, in
  • the object underlying the invention is therefore to provide a controlled cooling. This means that it should be possible to cool individual areas, in particular the aforementioned hot spots, in a particularly efficient manner by targeted cooling.
  • Moldings proposed which form the cavity for receiving the casting material, wherein at least one of the mold parts is formed as a molding mask, the mold having a cooling device, wherein the cooling device comprises a plurality of nozzles for spraying a fluid, wherein the nozzles on the back of the molding mask are prepared.
  • Two moldings usually form the cavity for receiving the
  • At least one of the molded parts or else both of the molded parts may be formed here as a molded part mask.
  • the area available for cooling is still substantially larger in relation to the mass to be cooled than in conventional molds.
  • the cooling of the molding mask by evaporation or partial evaporation of the fluid is not only faster, but they can also be targeted overall io done. That is, it can specifically target the aforementioned hot spots
  • the volume flow of each nozzle is individually controllable. That is, it can be targeted over the surface of the 5 back of the molding mask cooling.
  • the temperature distribution at the back of the molding mask is according to a further feature of the invention, for example by a
  • thermocouples which are arranged at the back of the molding mask, determined, wherein, depending on the temperature distribution by a regulation of Volume flow for each individual nozzle can be fixed. In particular, this is z. B. reaches a uniform temperature distribution over the surface of the back of the molding mask.
  • the molding mask indicates a closed housing chamber
  • Molding mask the heat dissipation during mold filling in
  • the closed housing chamber prefferably has a cooling device.
  • the cooling device when water is used as the cooling medium, a cooling device is required to return the evaporated water to the liquid state.
  • the cooling device comprises a heat exchanger.
  • the closed housing chamber has a trough for collecting the fluid, wherein the trough is connected by a line to the nozzles for supplying the nozzles with the fluid. From this it is clear that the cooling takes place in a closed system, and in particular by the heat exchanger, the cooling or condensation of the
  • Fig. 1 shows the mold in a schematic
  • the casting mold generally designated 1, comprises two mold parts 3 and 4 which form a cavity 5 into which the casting material is introduced.
  • the molded part 3 is in this case formed in the manner of a molded part mask 6.
  • the i o molding mask 6 has on its back a structuring 8, which leads to an enlargement of the surface of the molding mask on the back and thus an improved heat transfer.
  • the molding mask 6 also shows webs 7, with which the molding mask 6 is supported relative to a base plate 9.
  • the base plate 9 takes several nozzles
  • the individual nozzles 10 are connected via lines 12 with electrically controllable valves 13 in connection, the valves 13 are connected via a common line 15 to the trough 17, from which by a pump
