  • Patent number: 4768943
    Abstract: There is disclosed apparatus for use in forming hollow plastic drumsticks wherein plastic is injected into annular spaces formed between core pins and outer mold surfaces formed by cavities on the inner faces of mold members when engaged with one another. Upon hardening of the hollow plastic bodies within the annular spaces, the mold members are moved apart to a position in which the core pins about which plastic bodies are formed are moved laterally to positions in which a means surrounding each of the pins may be moved longitudinally along them in order to eject the molded bodies therefrom. In preparation for a subsequent molding process, the ejecting means is returned to its original position, the mold members are returned to their original position in which the core pins are disposed within the outer mold surfaces.
