Abstract
A lower mold made of a metal mold is disposed on a stool and an upper mold consisting of a sand mold is guided and fitted to the lower mold in such a manner as to define a cavity for a product. Tubular members are disposed at several positions in such a manner as to penetrate through the upper and lower molds and the cavity. A cooling plate equipped with cooling nozzles fitting to the projecting ends of the tubular members from the upper mold is disposed in such a manner as to clamp the upper and lower molds between it and the stool. The cooling nozzles are communicated with a cooling medium tube disposed on the cooling plate so that a cooling medium supplied to the cooling medium tube is uniformly distributed to the cooling nozzles.
