Abstract

PURPOSE:To enable the cooling in corner and pocket parts and to produce a casting mold by which castings having no surface defects and having good shapes and dimensional accuracy are obtained by forming the casting surface part of the mold with a mixture of molding sand and steel balls. CONSTITUTION:In the stage of forming the casting surface of a casting mold between the metallic flask 2 on a molding board 1 and a wooden pattern 3, a mixture 6 of steel balls and molding sand such as zircon sand is used in thick walled parts, corner parts, pocket parts, etc. like face sand by using a binder. Ordinary molding sand 4 is thereafter placed around the same, whereby the casting mold is formed. Steel balls which are sized about 2-30 times, more preferably 2-3 times the diameters of the sand are suited for the above-mentioned steel balls. Silica sand, chromite sand, etc. are used for the molding sand. If the wall thickness of the mold is large, it is possible to reduce the required amt. of the steel balls or to improve the effect of cooling by disposing proper scrap materials for cooling in the positions in proximity to the outer side of the casting surface.
