Abstract: A die casting mold part, which may be mounted on or applied to a die casting mold to provide for the molding and shaping of a variety of projections from the molded article and a simple and sure release from the mold of such projections including a plurality of projections lying closely adjacent to one another and extending outside the mold separation plane. The mold part includes segments, which are received in a bore that guides them and holds them together to form a die casting cavity, the segments together thus forming a mold at one of their ends. On their opposite end they flare outwardly and are mounted pivotally on a central control shaft so that they are caused to be opened where together they formed a mold, by relative movement between the control shaft and bore.
