PURPOSE: A system for controlling the temperature of a mold is provided to shorten the cycle time of forming, and to reduce the consumption of energy by quickly exchanging heat. CONSTITUTION: A closed loop passes through a circulation pump(12b), a heater(14), a mold(20), and an auxiliary tank(13) relieving the back pressure of circulating water introduced from the mold and separating air from the circulating water. Another closed loop passes through a cooler(11) and the auxiliary tank. Hot-water circulates through the auxiliary tank, the circulation pump, the heater, an expanded rubber hose(15), and the mold when heating the mold. Cold water circulates through the cooler, the auxiliary tank, the circulation pump, the heater, the expanded rubber hose, and the mold when cooling the mold.
