  • Patent number: 4342442
    Abstract: Mold for injection molding battery containers which include a plurality of thin resilient ribs integral with and projecting at acute angles from the inside walls thereof into the cell compartment(s) to hold the battery's innards therein. The core of the mold includes a mandrel defining the cell compartment. The mandrel has dovetail-like mortises therein and complementary-shaped ejector bars reciprocally slideable within the mortises between retracted and extended positions to facilitate stripping the container from the core. The rib-forming portion of the mold cavity is formed in the side walls of the ejector bar. The ejector bars travel with the container during at least part of the ejection cycle so as to free the rib from the rib-forming cavity without untoward resistance or permanent deformation of the ribs.
