うになした成形用金型。A mold for molding a cylindrical rubber or resin product, which is equipped with an upper mold, a lower mold, and a core mold that is inserted into a cavity shaped by these. An outer cylindrical core with a tapered inner diameter surface that almost matches the surface is inserted, and an inner cylindrical core with a tapered outer diameter surface that fits with the inner diameter surface of the outer cylindrical core is inserted into the outer cylindrical core. The molding die is configured such that the outer cylindrical core is expanded by pushing the cylindrical core, and the outer diameter surface of the outer cylindrical core is brought into close contact with the end surface of the cavity.
