When in use, water is added through the water inlet, and the inside of the water circulation pipe, the water inlet groove and the water outlet groove is filled with water. Then the water pump is started to circulate the water in the water circulation pipe, the water inlet groove and the water outlet groove. Due to the heat conduction of the mold, the water is heated.
