Abstract

PURPOSE:To cast a casting having rugged patterns easily by dissolving the surface of a foamed synthetic resin with an org. solvent or by heating to form rugged patterns, and molding a mold provided with reverse rugged patterns with molding sand by using this as a pattern. CONSTITUTION:The surface of a foamed synthetic resin body 1 such as foamed styrene, foamed urethane or the like is dissolved with an org. solvent such as thinner or a heating element such as a hot iron to form rugged patterns a. Then, the foamer synthetic resin pattern 1 having the above-mentioned rugged patterns is buried in the molding sand 2 prepd. by mixing 1 part a self-curing binder such as furan, phenol or urethane with 100pts. molding sand. The molding sand 2. Cures and acts upon the pattern to cause the shrinkage of the pattern 1 by the binder, after which the paterrn is stripped, whereby a mold 3 is made. Molten metal is charged into such mold, whereby the castings having the rugged patterns are easily mass-produced.
