ABSTRACT:
The present invention aims to allow production of a molded item having a highly precise shape. A molding metal mold is provided having a movable metal mold (first metal mold) and a fixed metal mold (second metal mold) defining a cavity therebetween in which a molded item is produced. The movable metal mold has a first convex taper tapering toward the fixed metal mold. The fixed metal mold has a first concave taper fittable with the first convex taper. The first convex taper and the first concave taper are arranged so that, when fitted to each other, respective taper surface abut to each other first, and then a clamping force of the movable metal mold and the fixed metal mold causes an abutting between an end surface and a bottom surface which are respective parting surfaces of the movable metal mold and the fixed metal mold around the cavity. The molding metal mold is used to produce a molded item by means of injection molding, for example.
