ABSTRACT:
In an injection mold for molding an article having an undercut at at least one end portion, the movable mold half has a slide core which defines the inner surfaces of the end portion and the undercut, and a main body which defines the inner surface of the other portion of the article. The slide core is divided, at the portion defining the inner surfaces of the end portion and the undercut, into a plurality of pieces in the direction perpendicular to both the ejecting direction and the direction in which the slide core is moved in perpendicular to the ejecting direction when the molded article is ejected from the mold. At least one of the pieces is adapted to be slid along an inclined surface which is at an angle to the ejecting direction larger than the angle at which the inclined surface or surfaces for the other piece or pieces are to the ejecting direction.
