PURPOSE:To prevent a mold from dewing due to supercooling of the same by heating rapidly cooling water, by taking out timing for interruption of an automatic continuous molding from an injection starting signal of an automatic control circuit of a molding machine and in the case when an interrupting period becomes layer than a predetermined period, a control circuit of a temperature of cooling water of cooling equipment of the mold is worked. CONSTITUTION:In the case when an automatic continuous cycle of an injection molding machine falls within a predetermined period set up in a timer 2, the timer 2 is reset up at every cycle, in an automatic continuous operation control circuit. On the other hand, in the case when the predetermined set period has elapsed, a heater 8 in cooling equipment is electrified by working the timer 2 and cooling water is heated. In the case where interruption of the injection molding machine has completed and the same is operated again, if the next cycle is shorter than the predetermined period set up in the timer 2, the timer 2 is reset automatically and operation is reopened. With this construction, a mold can be cooled by a cooling medium of a sufficiently low temperature, along with shortening of a necessary period for cooling a processing period is shortened and working efficiency of facilities is improved.
