Abstract

PURPOSE:To precisely control the temperature of an injection mold by detecting the temparature of the molten resin injected into the mold and that of mold cooling water, estimating the future temparature of optional places in the mold on a real-time basis by means of a predefined expression and regulating the temperature of cooling water. CONSTITUTION:An injection mold is composed of a fixed mold 10 and a movable mold 12 and equipped with a cooling water pipeline 32. The temperature of cooling water thetaw detected by a temperature sensor is transmitted to a mold temperature estimation device 46 and that of molten resin thetar detected by a resin temperature detector is also transmitted to this unit 46. The mold temperature estimation unit 46 calculates the future mold temperature thetai at optional places in the mold on a real-time basis by means of a predefined arithmetic expression with the temperature of molten resin thetar and that of cooling water thetaw, every time it receives the instruction Ce of estimation start and transmits them to a mold temperature control unit 48, which calculates a heat quantity and sends the instruction of a calorific valve Ch to a heater for cooling water. Owing to such structure, it is possible to minimize the fluctuation in mold temperature and to continuously obtain stable and high-quality molded products.
