    摘要: A mold clamping device for an injection molding machine wherein a movable table which supports a movable mold is moved in directions approaching and moving away from a fixed table which supports a fixed mold to thereby bring the molds into open and closed states, and wherein mold clamping is effected in a closed state of the molds by mold clamping cylinders. The mold clamping device includes tie rods for guiding the movement of the movable table, the tie rods projecting upward from the fixed table and being each provided with an engaging groove such as threads or the like formed on the outer peripheral surface of its portion projecting from the movable table to the side opposite to the fixed table in the closed state of the molds; and split mold-like locking members capable of engaging with and disengaging from the tie rods each through each engaging groove in the closed state of the molds, the locking members being slidable in the axial direction of the tie rods. The mold clamping cylinders are disposed between the locking members and the movable table. Since the tie rods which receive the mold clamping reaction are so constructed as to also be employable as guide members for guiding the movement of the movable table, it is possible to attain a structural simplification and reduction in size in addition to advantage in terms of maintenance.

    摘要: An injection molding machine is disclosed in which molten resin from an extruder is injected into the cavity of a mold through a nozzle. A runner body disposed between the mold and the extruder has a substantially L-shaped hot runner for supplying the molten resin from the extruder to the mold therethrough. The runner body is pivotably supported by a support assembly and is horizontally slidable relative to the support assembly to accommodate thermal expansion, whereby the nozzle mounted on the runner body can be brought into or out of intimate contact with the mold. To accommodate the thermal expansion of the runner body only toward the extruder, a stopper is provided on the base frame.

    摘要: In a cage position detector for a hydraulic elevator, there is provided a detector for measuring the time duration of the power failure, when the power fails. An amount of sinkage of a cage during the power failure is obtained by the time duration of the power failure and an average sinkage amount per unit time provide in advance. A cage position, which has been detected just before the power failure, is corrected by the above obtained amount of sinkage of the cage. A cage position, from which the elevator is to reopen a normal operation for service after the recovery of power, is specified by the corrected cage position.According to the present invention, even though the cage sinks during the long power failure, it is prevented to lose the true present position of the cage, from which the elevator is to reopen the normal operation after the recovery of power.
