The input end of the water pump 502 draws cooling water from the inside of the refrigeration box 501, and the cooling water is transported to the inside of the connecting pipe 503 through the output end of the water pump 502. Then the cooling water enters the inside of the annular pipe 504, and the cooling water contacts the outer surface of the lower mold 2 through the annular pipe 504, thereby cooling the lower mold 2.
