<P>PROBLEM TO BE SOLVED: To provide a casting mold which can suppress the antecedent inflow of a molten metal as much as possible. <P>SOLUTION: The casting mold is equipped with: a cavity 4A provided with a gate 41; a runner 3 extending in a linear shape; and a land feed 51 going from the runner 3, branched at a branched part 31, and extending in the orthogonal direction of the runner 3 so as to reach the gate 41, and a molten metal is fed from the runner 3 to the cavity 4A via the land feed 51 and the gate 41. Regarding the branched part 31 of the casting mold, the curvature radius R<SB>1</SB>of the corner part 31A on the lower side is smaller than the curvature radius R<SB>2</SB>of the corner part 31B on the upper side. <P>COPYRIGHT: (C)2011,JPO&INPIT |
