A molding device a molding machine with both fixed and movable side molds and which has cavities for molding a product. An injection cylinder injects resin into the cavities and a mold driving control performs the opening and closing operations of the molds. During the molding cycle, the cavities are heated by a high frequency heating system consisting of a coil, oscillation control section for inducing high frequency oscillation to the coil during the opening of the mold and stopping the high frequency oscillation during the closing of the molds. A mold temperature detector having a temperature sensor measures the temperatures of the molds and a temperature control initiates the circulating of a cooling medium within a circulating pathway which is provided within the molds.
