MOLD TEMPERATURE CONTROL APPARATUS AND CONTROL METHOD THEREOF

摘要

An apparatus and a method for controlling the temperature of a mold are provided to improve heating efficiency of the mold by supplying water that is heated while passing through a heat exchanger. An apparatus for controlling the temperature of a mold comprises a water feeding line(100), a heating device(200) for heating water, an air feeding line(300) connected to the water feeding line to supply air, and a discharge line(400) for discharging the air and water. The heating device includes a heating tank(210) for heating a heat medium, a pump(220) for circulating the heat medium, and a heat exchanger(230) for heating the water. A pump(101) is installed in the water feeding line and a pressure meter(102) is installed between the pump and the heating device. A pressure controller(103) is provided in the water feeding line to control pressure of water supplied from the water feeding line.
