ABSTRACT:
A first sleeve30regulates the horizontal relative position between an upper mold10and a lower mold20that are insertable into the first sleeve30from its both end sides. A second sleeve40provided inside the first sleeve30and surrounding the outer periphery of a molding surface21of the lower mold20supports at least part of an outer peripheral portion of a molding material50placed on the molding surface21of the lower mold20, thereby preventing position offset and slip-off of the molding material50. In this state, the molding material50is press-molded between the upper mold10and the lower mold20.
