摘要： PROBLEM TO BE SOLVED: To provide a method for controlling the temperature of a mold which prevents the thermal distortion of the mold, whereby the growth of burrs and flashes can be restrained.
SOLUTION: The invention relates to the method for controlling the temperature of the mold in a die-casting process. There is provided, near the periphery of the mold 1, a heating path 2 through which an electric heater or a heating medium is connected to the mold inside to control the temperature of the mold. The temperature of the mold is controlled by actuating a temperature controller 5 with an output from a control circuit 6 based on temperature information from a peripheral temperature sensor 3 and a product part temperature sensor 4 so that the temperature near the periphery of the mold is higher than that at the product part which is the center part of the mold when molten metal commences to flow into the product part (cavity) 11 by mold clamping.
