PURPOSE: To provide a method for molding in which the cleaning of a core after the mold is opened is easy in the case of molding a resin molding, and the accuracy and the yield of the molding can be stably maintained for a long period. CONSTITUTION: A core 31 for forming an undercut part is held in a slide core 30, the core is disposed between molds 10 and 20, and a resin molding is molded. In the case of opening the mold in which the molding is molded, the core is moved together with the slide core out of the mold. This is adapted for molding an optical component. |
