Abstract
A lower mold includes: refrigerant ejection ports in its press-molding surface; refrigerant guide grooves in the press-molding surface to guide a refrigerant ejected from the refrigerant ejection ports to an outer portion of the press-molding surface with the refrigerant being in contact with a workpiece; a single connecting groove connected to the refrigerant guide grooves and formed at the outer portion of the press-molding surface into which the refrigerant flows through the refrigerant guide grooves; and discharge ports in the connecting groove. Each of the refrigerant discharge ports is formed at a part of the connecting groove apart from the connecting points between the connecting groove and the refrigerant guide grooves.
