Abstract: The die casting machine comprises a mold closing actuator capable of selectively inducing a closing pressure on first and second platens for forcing them towards a closed position in which their mold portions are pressed against each other along a parting line. An injection sleeve is movable relative to the mold portions between a distal position in which the injection sleeve and the mold portions are spaced apart; and an injection position in which the injection sleeve engages the mold portions at an inlet opening when the first and second platens are in their closed position. The injection sleeve applies a transverse contact pressure when it engages the mold portions. The closing pressure is unevenly distributed on the platens so as to compensate the transverse contact pressure to have a resulting effective molding pressure on the mold portions that is substantially evenly distributed across the parting line.

Abstract: The mold clamping device is provided with a first platen to which a stationary mold is attached. A movable mold unit is capable of approaching and moving away from the stationary mold. A second platen is linked to the first platen via a tie bar. When the movable mold unit and the stationary mold are closed, a wedge member is driven onto the movable mold unit to generate mold clamping force. The second platen has a pressure receiving surface. The pressure receiving surface receives, through the wedge member, mold opening force that is generated by filling, with a molding material, the stationary mold and the movable mold unit that are in the closed state.

Abstract: A mold fastening device has a fixed die plate, a rear plate, a movable die plate that can move back and forth, a toggle mechanism, and a drive motor that drives a cross-head. The position where the cross-head should be stopped is associated with the rate at which to accelerate the cross-head from that position or the rate at which to decelerate the cross-head to that position. The cross-head is operated at an acceleration that corresponds to that position. The drive motor is thereby driven at a constant output torque, regardless of the position of the movable die plate. Further, the time for opening and closing metal molds can be shortened.
