摘要:
A molding apparatus includes a cavity mold, a core mold, a core pin, and a cavity pin. After molten resin has been filled in a cavity, at least one of the core pin and the cavity pin is moved to be pressed onto the molten resin so that a part of the molten resin is compressed before the molten resin is cured, and a molded hole is formed by cutting off the compressed part of the molten resin by moving the core pin and the cavity pin.
