Abstract

PURPOSE: To prevent the reaction of cast metal and molding components and improve workability by forming a heat-resistant film on the surface of molding dies.
CONSTITUTION: A pattern 1 is set in a die 4 and melt 10 of molding material is filled in a molding cavity 11 through the injection port 5 of an upper die 4a. The die 4 is then immersed in cold water to allow the melt 10 to solidify. Next, the die 4b, fixing base 9 and pattern 1 are removed, then a recess 6 corresponding to the outside shape of the pattern 1 is formed in a die 12. Then, a heat-resistant protecting film 7 is formed on the surface of the recess 6, after which the molding die material of silica base contg. a binder and a small amount of hardener is packed in the recess 6 and the fixing bed 9, die 4b are mounted to the dies 12, 4a and the filling is allowed to set. This yields the molding of the pattern 14 in which thus hardened material is used as base 13 and a film 7 is firmly stuck on the surface of this.
