Claims

[Scope of utility model registration request]

The upper mold and the lower mold are closed together to close the molding gap, and the molding material is injected into the molding cavity to perform molding, and then the upper mold and the lower mold are separated to open the molding surface to obtain a molded product. In a molding device in which a slide core forming an undercut portion is attached to the other mold opposite to the mold to which the molded product is to be attached when the upper mold and the lower mold are separated, said one The slide core is integrally bent from a template provided between the molds toward the one mold, and comes into contact with the back surface of the slide core with the molds closed together. a protrusion that supports the force in the retreating direction of the core and maintains the positioned position of the slide core, and has one end facing the molding surface on the dividing surface between the one mold and the slide core; The slide core is provided with a guide hole which is recessed so as not to face the slide core and has an end surface against which the slide core abuts and is positioned. The one mold and the mold plate are connected with shoulder bolts so that there is a gap as large as the amount of protrusion of the protrusion between the mold plate and the mold plate, and the mold plate side of the slide core is divided. A forming device characterized in that the surfaces are pulled apart and released.
