    Abstract: An injection molding machine with a vertically displaceable closing unit, comprises a plate-like lower yoke as the counterpressure plate; a plate-like upper yoke as the stationary mold clamping plate; at least three vertically aligned struts connecting the lower yoke and the upper yoke with each other in a force-locked manner; as well as another plate-like element serving as the displaceable mold clamping plate, which is displaceable on the struts by one or more driving cylinders having a small cross section and a large stroke length. The displaceable mold clamping plate is displaceable by one or more driving cylinders stopped on the displaceable mold clamping plate and on the counterpressure plate, such that molding tool halves arranged on surfaces of the mold clamping plates can be driven from a maximum spacing into a position of mutual abutment, and vice-versa. In the abutting position, a short-stroke cylinder with a larger cross section and acting between the counterpressure plate and the displaceable mold clamping plate can be engaged to generate the required closing pressure. The engageable short-stroke cylinder is a piston-and-cylinder system to which a fluid medium can be admitted. This system can be retracted and extended in the abutting position from the closing unit in the horizontal direction between the counterpressure plate and the displaceable mold clamping plate.

    Abstract: A closing unit for injection mold machines is disclosed which generally includes two end plates, guide crosspieces connecting the end plates at a distance from one another, an intermediate plate which is parallel to the end plates and displaceable longitudinally relative to the guide crosspieces and moving cylinders which abut an end plate and act at the intermediate plate via their piston rods. The moving cylinders also displace the intermediate plate along the guide crosspiece in the closing and opening direction to vary its distance from the other end plate. The intermediate plate and the other end plate form a gripping plate for the two mold halves of a form tool which is brought into its closing position by the two gripping plates. Increased closing force may be applied to the form tool at a central die via a pressure cushion insertable between one end plate and the intermediate plate.

    Abstract: The present invention provides a mold clamp apparatus having a novel construction wherein, though the advance of the movable platen is blocked, it is possible to perform a powerful mold clamping operation as in case of a direct compression operation, and it is also possible to make a support of the movable platen accurate by connecting the tie bar to the fixed platen, and further it is also possible to perform a high-speed mold-closing operation and a powerful mold-clamping operation continuously.

    Abstract: A molding press has hydraulic transporting means for rapidly moving a mold-supporting movable platen toward and away from a fixed mold-supporting platen. A hollow main piston is connected by coupling means with a connecting beam projecting from the movable platen to open and close the mold with great force. Before the transporting means retract the movable platen, the coupling means is withdrawn from the path of the beam so that the beam can enter the hollow piston whereby the length of the machine is reduced.
