| 摘要 |
A temperature control unit for dies and molds, particularly for pressure die-casting or injection-molding of aluminum and alloys thereof, plastic materials and the like, comprising a die or mold cooling circuit (1) though which pressurized water flows. A water feed pump (2) is connected to the circuit (1) and is adjustable to a pressure which is higher than the evaporation pressure of water at a preheating temperature of the water, which can be detected by a first sensor (3) for detecting the temperature of the water. The circuit (1) includes a circulation pump (11), a water overflow valve (12) which can be set to a lower pressure than the feed pump, and a heating unit (13) which is controlled by the first temperature sensor (3). A die or mold temperature sensor (15) is further provided which controls the feed pump (2). <IMAGE> |
