  • Patent number: 4620958
    Abstract: In order to mold a plurality of articles (20--20) which are disposed in a line, a molding arrangement in an apparatus (60) includes a plurality of cavities (109--109) which are spaced equidistantly from an infeed sprue (131). A primary network of a distribution system (50) through which an injection molding material is flowed from the infeed sprue to cavity gates (151--151) is disposed substantially along a vertical plane (150). Afterwards the injection molding material which has been flowed from the primary network and along a secondary network into the cavities is solidified. Then the primary network is exposed by causing wedge blocks (79--79) to be disengaged from each other and from an adjacent stationary platen (62) and cavity plate (90) by movement of each block in a direction transverse to the plane.

  • Patent number: 4524516
    Abstract: A composite article of this invention is made by successive molding steps and comprises an insert assembly that includes a metallic portion and a plastic locating framework in which the metallic portion is precisely mounted with respect to references points on the locating framework. The locating framework is mounted within a housing with the insert assembly precisely positioned with respect to the housing to cause the metallic portions to be substantially precisely positioned with respect to an external surface of the housing. In one embodiment, which is a hand tool that is moved slidably along a connector to sever conductors, a cutting blade is substantially precisely positioned in the locating framework of the insert assembly. Plastic is flowed about the framework in a mold cavity to form the housing.

  • Patent number: 4354995
    Abstract: Methods are provided for making a composite article by successive molding steps. The article comprises an insert assembly that includes a metallic portion and a plastic locating framework in which the metallic portion is precisely mounted with respect to references points on the locating framework. The locating framework is mounted within a housing with the insert assembly precisely positioned with respect to the housing to cause the metallic portions to be substantially precisely positioned with respect to an exernal surface of the housing. In one embodiment, which is a hand tool that is moved slidably along a connector to sever conductors, a cutting blade is substantially precisely positioned in the locating framework of the insert assembly. Plastic is flowed about the framework in a mold cavity to form the housing.
