Abstract: A polymeric injection mold has stationary and movable parts mating at a parting line. The polymeric part has one or more re-entrant surfaces on both sides of the parting line, wherein the re-entrant surfaces are defined by slide bar projections inserted into the mold. The slide bar projections are attached to slide bars that pass through tapered slots in the side walls of the stationary and movable sides of the mold and are inclined at an angle to the centerline of the mold. The slide bars of the stationary side of the mold are removably connected to pull bars, wherein the pull bars are rigidly attached at their opposite ends to the movable side of the mold. When the movable side of the mold is withdrawn, the injection molded part is pulled out of the stationary side of the mold when the slide bar projections clear the re-entrant surfaces.
