  • Patent number: 9289929
    Abstract: A molding arrangement serves for molding articles at each stroke of an injection-molding machine in which an injection mold is mounted. The articles are composed of components made of different materials in cavities formed in the injection mold, with each cavities corresponding to the shape of a component whereby identical cavities are separated by angular distances and placed at equal distances from a central axis of the injection mold and parts of the cavities are formed in a separately movable section of the movable mold half. The injection molding arrangement includes an operation part for displacing the section to-and-fro between closed and open positions of the injection mold and in open positions to turn the section about the central axis angles corresponding to the angles between the cavities to form whole cavities in the injection mold in closed position.
