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.

摘要： PROBLEM TO BE SOLVED: To provide a mold capable of dealing with various type moldings by replacing little components by arbitrarily setting a molding drawing direction without changing a moving direction of a slide core. SOLUTION: A fixed main mold has a first angular cam 41 and a second angular cam 42. A movable main mold has a first slide core 51 sliding in a moving direction X, and the core 51 has a second slide core 52 sliding in a moving direction Y. When the mold is opened, the cam 41 slides the core 51 at a moving amount Sx, and the cam 42 moves the core 52 at a moving amount Sy. The contact state of the cam with the core is changed to alter a mold drawing direction W of the core 52.
