  • Patent number: 6527536
    Abstract: A mold-thickness adjustment mechanism is provided which uses intermediate toothed wheels engaging with a pair of toothed wheels on a tie-bar side. The mechanism includes a toothed wheel on an outer surface of a pressure-receiving plate and toothed wheels with a large diameter for mold-thickness adjustment provided together with a toothed wheel-driving motor on the side of the pressure-receiving plate on the central portion of an outer surface of the pressure-receiving plate. Intermediate toothed wheels are arranged between the toothed wheels with the large diameter and a pair of toothed wheels of one side of the pressure-receiving plate to engage each other. A pair of the toothed wheels is designed to rotate by rotation of the intermediate toothed wheels at the same time, whereby a diameter of the toothed wheel with the large diameter is constituted approximately equally to the breadth of the plate body of the pressure-receiving plate.
