Filed: 1988-12-16
Abstract: PURPOSE:To make the temperature control of a cavity surface, onto which precise and minute projected and recessed surface is provided, possible by a method wherein a mold is heated with a high frequency induction heating means and at the same time cooling medium, the temperature of which is held at the predetermined value, is circulated. CONSTITUTION:A temperature controller 14 controls the temperature of cooling medium to the predetermined value and, at the same time, circulates the cooling medium through a circulating path 14A in a fixed mold 2A and a movable mold 2B. The cooling medium circulates in the molds on one hand and the cavity of the mold is rapidly heated through the high frequency induction oscillation up to the peak temperature tB. When the peak temperature tB is detected with sensors 20A and 20B, a temperature detecting means 22 sends the oscillation stop signal to a high frequency oscillation controlling section 16A. At the same time, a moving means 18D retreats a heating coil 16B. Though the temperature of the molds lowers the temperature lowering curve (b) is formed in the form of a certain curve ranging from the peak temperature tC to the injection temperature tB through the instantaneous heating by high frequency induction heating and the cooling operation by the cooling medium during heating, resulting in keeping the injection temperature tC constant.
