Forced cooling casting apparatus
First Claim
1. A forced cooling casting apparatus comprising:
- a stool;
upper and lower molds disposed on said stool;
a plurality of tubular members disposed in such a manner as to penetrate through said upper and lower molds and through a cavity defined by said upper and lower molds; and
a cooling plate disposed on said stool by guide members, said cooling plate being equipped with a plurality of nozzles for supplying a cooling medium, said nozzles fitting in upper ends of said tubular members, and with a cooling medium tube having a cooling medium coupler and communicating with said cooling nozzles; and
abnormality detector means for sensing an abnormal setting of said cooling plate on said stool and an abnormal fitting of said cooling nozzles in said tubular members.

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.
