ることを特徴とする樹脂成形型。[Claims for Utility Model Registration] A core and a cavity that form a molding space between opposing molding surfaces are provided, an ejector pin that is slidably supported through the core and is used to remove the molded product from the mold, and the ejector pin. A demolding mechanism is provided, the demolding mechanism having an ejector plate that supports the ejector plate, and a demolding actuator that strokes the ejector plate in the demolding direction, and a part of the core is provided with an ejector plate that moves in the stroke direction of the ejector plate with respect to the core body. An undercut molding part is provided so as to be separable in the same direction as the undercut molding part, an undercut molding space for molding the undercut part of the molded product is provided between the undercut molding part and the core body, and a slide rod is connected to the undercut molding part. The slide rod is supported by the ejector plate so as to be slidable in the stroke direction of the ejector plate, and between the slide rod and the ejector plate,
The slide rod is provided with a spring that urges the slide rod to slide in the direction toward the cavity, and the slide rod is provided with a spring that urges the slide rod to slide toward the cavity at a position before the maximum stroke position when the ejector pin is removed from the mold, and A resin molding die, characterized in that a stopper is provided for regulating the undercut molding portion at a position away from the core body.
