PURPOSE: A cooling system for an injection molding is provided to reduce the cooling time of an injection molding because specific hot spots are easily contacted to a cooling pin and directly cooled by supplying a low temperature compressed air to the cooling pin. CONSTITUTION: A cooling system for an injection molding comprises an air line(100), a refrigerant circulation line(200), and a core pin. The air line comprises an air inflow line(102) and an air outflow line(104). Air compressed by a compressed air feeder is supplied to an evaporator(130) through the air inflow line. The low temperature compressed air generated in the evaporator is discharged through the air outflow line. The refrigerant circulation line comprises a compressor(220), an oil separator(230), a condenser(240), a liquid separator(250), and an expansion valve(260).
