  • Patent number: 4057381
    Abstract: A rotary press with a rotary driven matrix table for holding matrixes having boreholes. During rotation of the matrix table, top and bottom dies are moved in their axial direction towards and away from each other for pressing injected moldable material in the boreholes of the matrix. For production of profiled articles, the bottom and/or top dies are constructed as one outside and at least one inside die which are movable independently of each other. For pressing movement of the outside and inside dies, at least one profiled press roller is provided to assign different pressing paths to the outside and inside dies. The press rollers are provided with a rotary deep-cut groove for guiding the inside die to which a nose-shaped guide head is assigned for engaging the groove. The press rollers are constructed as two exterior disks for guiding the guide surfaces, and one interior disk for guiding the inside die by means of the nose-shaped guide head.

  • Patent number: 3964852
    Abstract: The device is of a type including a multi-part hollow mold mounted in a closure assembly, having a frame and movable in a housing between a blow station and a plasticating unit, on relatively movable mold platens carried by two supporting bars extending below the hollow mold in the closure assembly. A locking mechanism is provided on the upper parts of the mold platens and comprises a locking bush firmly secured to one mold platen and a locking rod rotatably mounted in the other mold platen but fixed against axial displacement relative thereto. The locking rod has a lock head, designed as a symmetric hammer head, adapted to lockingly engage in the locking bush which has an opening conformable to the hammer head and formed with diametrically opposite catch webs, the hammer head having faces adapted to engage behind the catch webs upon rotation of the locking rod.
