  • Patent number: 10668656
    Abstract: In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.

  • Publication number: 20200078997
    Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.
