  • Internally locked core centering mold assembly
    Patent number: 4278417
    Abstract: A mold assembly is described for molding smooth-bottomed battery cases in which the necessary compression locking of the free ends of the elongated cantilever mounted cores is achieved by providing transverse locking pins which are carried within, and actuated to extend from, the interior of the cores themselves. Since no locking pins extend from the cavity, the interior surface of the base wall of the battery case is formed relatively smooth and flat.
