Abstract
A lower mold includes: refrigerant ejection ports in its press-molding surface; and three or more independent refrigerant guide grooves extending in the press-molding surface from the refrigerant ejection ports to guide the refrigerant ejected from the refrigerant ejection port to an outer portion of the press-molding surface with the refrigerant being in contact with a workpiece. Each of the refrigerant guide grooves neither branches halfway nor merges with the others of the refrigerant guide grooves to extend from the refrigerant ejection ports to the outer portion of the press-molding surface.
