PURPOSE: A rapid temperature control device of an injection mold for high gloss is provided to reduce heating energy and heating time by circulating the water in a closed circuit. CONSTITUTION: A rapid temperature control device of an injection mold for high gloss comprises a high temperature and a low temperature water tank(10,40), a heater(20), a mold(30), a cooling tower(60), and a heat exchanger(50). The heater presses the water of the high temperature water tank and produces the water of the high temperature by raising the temperature which generates phase change between water and gas of the water. The mold implements an injection molding process after pre-heating the mold through rapid heating by closed circulation of the water. The cooling tower supplies the cold water in order to lower the temperature of the cooling water. The heat exchanger heat-exchanges the cooling water of the low temperature water tank and the cold water of the cooling tower, thereby lowering the temperature of the cooling water.
