Abstract

PURPOSE: To provide a metal mold for casting which prevents the formation of blow holes by providing a well part to become head to the upper part of the place where it is a dead angle part for the flow of molten metal.
CONSTITUTION: When half-split molds 1A, 1B are mated and molten metal is flowed in through a sprue part 6, the molten metal flows into the cavity part 2 of the shape corresponding to a molding and the cavity part for head. The molten metal in the cavity part 2 solidifies by receiving the pressing effect of the molten metal in the cavity part 4 without forming any blow hole. In a dead angle part 3 where the flow of the molten metal flow is poor, the molten metal flows, but at this time the molten metal flows also into the well part 5 provided above the dead angle part 3 and the molten metal is filled in the dead angle part 3 by the pressing action of this molten metal, thus the molten metal solidifies without producing any blow hole.
