A wax liquid temperature control device of a wax injector is disclosed. In this device, a coal oil heat exchanger controls the temperature of the coal oil in a predetermined range. Then, the coal oil is transferred to a wax liquid temperature control cylinder to control the temperature of the wax liquid so that the wax liquid is retained in a proper temperature for being injected to a mold. Therefore, the wax liquid temperature control device of a wax injector may cool the wax liquid in the mold rapidly.
