Abstract:
1. A molding metal mold for forming a cavity between a first metal mold and a second metal mold and for molding a molded item in the cavity, wherein: the first metal mold comprises a first convex taper tapering toward the second metal mold; the second metal mold comprises a first concave taper fittable to the first convex taper; and the first convex taper and the first concave taper are formed so that, when fitted to each other, respective taper surfaces abut to each other first, and then a clamping force of the first and second metal molds causes an elastic deformation of at least one of the first metal mold and the second metal mold so as to cause an abutting between respective parting surfaces of the first and second metal molds around the cavity.
