<p>This invention provides a mold that can prevent molten metal from leaking out of it as well as from leaking onto a parting plane. The mold according to this invention comprises: a lower mold comprising a concave portion, having 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 having the shape of a casting, and forming a cavity that molds a casting, when the upper mold overlaps the lower mold; and wherein a structure is formed so as to have certain clearances between the lower mold and the upper mold such that the 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.</p> |
