<p>PROBLEM TO BE SOLVED: To provide a hot stamping mold having high cooling efficiency.SOLUTION: A hot stamping mold 1 comprises: a cooling path 5 through which cooling medium flows; and a plurality of circular cross section bodies 3. The plurality of circular cross section bodies are charged into the cooling path. The cooling medium passes between the circular cross section bodies and between the circular cross section bodies and an inner wall of the cooling path. A spherical body can be used as a circular cross section body. Further, the plurality of circular cross section bodies may be unified with each other, and circular cross section bodies contacting the inner wall of the cooling path out of the plurality of circular cross section bodies may be unified with the inner wall.</p> |
