Abstract
A midsole molding apparatus which enables production of a high-quality midsole is provided. The apparatus includes a through hole, which passes laterally through a midsole used for a shoe, to be integrally formed, preventing traces of forming the through hole from being left in the through hole and on the periphery of the through hole and a shaft mold crossing the inner space of upper and lower molds, forming extending portions such that the ends of the shaft mold extend beyond the boundary of the inner space, and seating the extending portions in press recesses of the upper and lower molds to seal the insides of the molds so as to prevent raw material from leaking from inside the molds when foaming and forming a midsole, to prevent parting lines and burrs from forming on the inner surface of the through hole passing laterally through the midsole.
