Abstract: A second pressure intensifying cylinder subchamber is employed for moving a pressure intensifying piston toward the other side, and the necessity for a control valve with a throttle is thereby eliminated. The pressure intensifying piston is incorporated integrally into a fluid cylinder, and, hence, the fluid cylinder can be installed in an even narrow space. A main cylinder chamber communicates with a pressure intensifying cylinder chamber in the interior of the fluid cylinder, and it is therefore possible to prevent such a situation that a high-pressure fluid sprouts out. A structure of the fluid cylinder is thus simplified enough to reduce the costs, and the safety is improved.
Abstract translation: 采用第二加压气缸副室将增压活塞朝向另一侧移动，从而消除了具有节气门的控制阀的必要性。 增压活塞整体结合在一个流体缸中，因此，液压缸可以安装在一个狭窄的空间。 主缸室与流体缸内部的加压气缸室连通，因此可以防止高压流体发芽的情况。 因此，液压缸的结构被简化为足以降低成本，并且提高了安全性。

Abstract: In an apparatus for generating clamping force in injection molding machines having stationary and moving platens, between which an injection molding die is mounted, and a traversing mechanism associated with the moving platen for opening and closing of the injection molding die, the present invention provides means for locking the traversing mechanism after the molding die has been closed. The clamping force required during injection is generated by at least one element made of a magnetostrictive material that is mounted between the traversing mechanism and the moving platen. Each magnetostrictive element is surrounded by a magnetic coil that is controllably energized to produce an alternating magnetic field which causes elongation of the associated element, generating the clamping force.

Abstract: A clamping assembly for an injection moulding installation includes a rigid, elongated positioning structure and an elongated clamping structure. A fixed platen is rigidly coupled to the positioning structure and articulatedly coupled to a first end portion of the clamping structure. Longitudinal, axially directed sliding bearings are formed integrally with the positioning structure. The assembly further includes a movable platen slidably supported on the bearings for a free, axially directed displacement with respect to the positioning structure towards and away from the fixed platen. A platen drive unit is articulatedly coupled to a second and opposite end portion of the clamping structure and to the movable platen for imparting that displacement to the movable platen.

Abstract: In a drive apparatus for a toggle-type mold clamping mechanism of a vertical injection molding machine, a drive motor movably supported on a guide table via rollers moves horizontally following the vertical movement of a ball screw, when a mold is opened or closed, with keeping the distance between the ball screw and the output shaft of the drive motor constant by means of connecting plates. As the ball screw is rotated by the drive motor via a first pulley, a second pulley and a belt wound around the first and second pulleys, a toggle arm of each of a pair of symmetrical toggle clamping mechanisms is bent to close or open the mold.

Abstract: A slidably attachable automated hydraulic cylinder system opens and closes the die halves of a casting machine. Cylinders are provided having integral vertical side grooves for mounting on the casting machines. The preferred hydraulic cylinder has a hollow piston rod connected to the piston and projecting from one end of the cylinder. A fluid flow line movable within the cylinder projects from the other end of the cylinder and slidably passes through the piston into the piston rod. Separate elements contact the piston at opposite ends of its stroke to move the fluid flow line and switch the fluid flow in the cylinder.
