  • Injection molding machine with vertical plasticizing unit
    Patent number: 7833008
    Abstract: An injection molding machine includes a clamping unit constructed for support of at least two molding tools to provide at least two different cavities. A first plasticizing unit is provided for charging one of the cavities in one of the molding tools, and a second plasticizing unit is provided for charging the other one of the cavities in the other one of the molding tools. The second plasticizing unit is hereby attached to a mounting in a substantially vertical orientation. The mounting may be mounted on one of the platens of the injection molding machine or on a frame which extends above the clamping unit.
    Type: Grant

  • Closing unit for an injection molding machine with stack mold
    Patent number: 7488167
    Abstract: A closing unit for an injection molding machine includes first and second platens, of which at least one is movable, and an intermediate plate disposed between the first and second platens. A molding tool is disposed between one of the first and second platens and the intermediate plate. In order to allow operation of the closing unit with intermediate plate also as a single-face mold for molding a single-component product, the molding operation between the other one of the first and second platens and the intermediate plate is disabled by a dummy tool or by securely fixing the intermediate plate to the other one of the first and second platens. Removal of an end product from the molding tool is realized by at least one ejector which is arranged in or on the intermediate plate.
