ABSTRACT:
A mold that can prevent molten metal from leaking out of it as well as from leaking onto a parting plane of the mold. The mold includes a lower mold having a concave portion that has the shape of a product, into which the amount of molten metal required to produce a casting is poured and an upper mold comprising a convex portion that has the shape of the casting, and forming a cavity that molds the casting, when the upper mold overlaps the lower mold. A structure is formed so as to have certain clearances between the lower mold and the upper mold such that molten metal is prevented from leaking onto the parting plane that is formed where the upper mold and the lower mold overlap, when the casting is produced.
