PROBLEM TO BE SOLVED: To provide a casting mold capable of improving heat resistance at an upstream side part of a branch point on a runner and suppressing generation of erosion caused by deposition and galling.SOLUTION: The casting mold comprises a cavity CA and a runner 11 for supplying molten metal to the cavity CA. The runner 11 has a branch point 13 for branching the molten metal supplied from a supplying port 10 to plural branched passages 111,112 extending toward the cavity CA. An upstream side of the branch point 13 is formed by a branch point forming body 2 made of tungsten alloy and made individually from a mold body 1. |
