    Abstract: A mold assembly for producing a plastic container having internal compartments separated by partitions. A male mold is slidably moveable into a female mold and includes a plurality of upstanding cores to form the container with injectors provided to force plastic melt between the molds and between the cores. A plurality of side locking members are reciprocably mounted in the cores and when extended contact adjacent cores limiting relative motion therebetween. The locking members form holes in the partitions formed between the cores. The locking members are withdrawn only after the plastic melt is cooled.

    Abstract: An injection mold assembly for formation of thin walled multi-partitioned plastic containers. An Array of cantileveredly mounted and spaced apart cores are extendable into a female mold assembly which includes a pair of side cavity cams and end cavity cams closeable upon the array, but spaced therefrom to form the plastic container therebetween. A plurality of side locking wedge shaped fingers are extendable into the slots spacing the cores apart. The fingers are arranged to extend into the opposite sides of the array of cores in a direction perpendicular to the longitudinal axis of the array spacing the cores apart while plastic is injected into the assembly by injectors mounted to the female mold. A pair of end pushers contact the two outermost cores in the array limiting outward movement of the cores during the injection step. The end pushers likewise extend in a direction perpendicular to the longitudinal axis of the array. In one embodiment, the fingers are moveable to and from the array by hydraulic cylinders and are moveable apart from the side cavity cams as the mold assembly is opened. In another embodiment, the fingers are removeably connected to the hydraulic cylinders and are mounted to the side cavity cams to move therewith as the mold assembly is opened.

    Abstract: An injection mold assembly having means to stabilize interior components. A male mold has a plurality of upstanding cores with free distal ends extending into a female mold. A plurality of wedges extending from the female mold are positioned between some of the cores to limit movement thereof as plastic material is injected into the mold assembly at other locations to cooperatively with the wedges limit movement of the free distal core ends.

    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.

    Abstract: A plastic injection mold having means therein for holding an insert to be secured in the formed product. A pair of complimentary sized mold sections are movable together, one mold section having a pin fixedly mounted thereto and extending toward a second pin slidably mounted in the second mold section and aligned with the first pin. In the preferred embodiment, a helical spring contacting the slidable pin urges the pin outwardly to initially hold an insert. As the mold closes, the pins are contacted together with the spring being yieldable to allow retraction of one pin and the transfer of the insert mounted thereon onto the second pin. In an alternate embodiment, the retractable pin is fixedly mounted to a movable plate having a spring loaded leg depending therefrom with the leg being contactable by the mold sections as the mold is closed for the retraction of the slidable pin and the transfer of the insert.
