A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

An automobile interior member which is represented by an instrument panel and to which an air bag device is to be assembled, is constituted by a main body portion and an air bag cover portion, the main body portion and the air bag cover portion being formed in a manner so that the main body portion is primarily molded (injection-molded) out of first thermoplastic resin material, and the air bag cover portion is secondarily molded (injection-molded) so as to be lapped with the main body portion on the back surface side. The second thermoplastic resin is oriented in a direction along a tear line (edges of rotational lid portions) of the lid portions (door portions) in the air bag cover portion so that the air bag cover portion is secondarily molded.

An apparatus for molding a resin product having a bottom plate, a pair of side plates, and a pair of flanges. The side plates are formed integrally with the bottom plate to extend from opposite sides of the bottom plate. Each flange is formed integrally with the associated side plate to extend inward from an upper end of the side plate. The apparatus has a pair of inner slidable cores that shape an upper side of the bottom plate, an inner side of the side plate, and a lower side of the flange. The apparatus also includes an intermediate core located between the inner slidable cores for determining the position of each inner slidable core. The apparatus further includes a sliding mechanism that slides each inner slidable core to a position spaced from the resin product while moving the inner slidable core and the intermediate relative to each other.
