Abstract: A clamping unit has a hydraulic actuating assembly including at least two locking cylinders provided with respective locking pistons, which are connected by piston rods to a movable mold carrier. Each locking cylinder contains a high-pressure chamber and a low-pressure chamber, which are adapted to communicate with each other through overflow passages formed in the associated locking piston. The overflow passages can be shut off by valve members. The hydraulic actuating assembly has an axis of symmetry, on which a drive cylinder and a buffer cylinder are centered. The drive cylinder serves to close and open the injection mold. The buffer cylinder is connected to the movable mold carrier and has a buffer chamber, which communicates with the low-pressure chambers of the locking cylinders. The locking cylinders and the buffer cylinder have steel tubes, which are connected at both ends to common cylinder covers to constitute a unit. The drive cylinder is coaxially surrounded by the steel tube of the buffer cylinder. The steel tubes of at least two locking cylinders are symmetrical to the drive cylinder.

Abstract: A motor-operated, direct-pressure type mold clamping apparatus is capable of high-speed mold closing and opening operations and of producing a required mold clamping force, without the use of a large-sized motor. In the mold opening and closing operations, a ball screw, in engagement with a ball nut which is movable in one with a moving platen, is rotated at high speed by a motor through gears and a clutch, so that a die is opened and closed at high speed. In a mold clamping operation, the ball screw is driven with a large rotatory force transmitted through a clutch and gears which, having a high reduction ratio, serve to increase the rotatory force of the motor. Thus, dies are clamped with a large clamping force.

Abstract: A mold clamping apparatus of an injection molding machine is provided, which is capable of uniformly applying a pressing force to a movable platen. A pair of annular wedge type connection members (21, 22) are disposed within annular hollow portions (16a) of driving pulleys (16), which are respectively fitted on ball screws (14, 15) threadedly engaged with heads of upper and lower toggle sections disposed symmetrically with respect to an axis of the mold clamping apparatus. To make an adjustment for eliminating mismatch between operational phases of the toggle sections of the toggle mechanism due to flexure of the same mechanism, an urged contact state of the connection member is released by loosening bolts (23), and the ball screws, rendered to be rotatable relative to the driving pulleys, are manually rotated so that the heads are aligned with each other. After completion of the adjustment, the driving pulleys are again rendered rotatable in unison with the ball screws. The heads then are moved through the ball screws toward the movable platen, and links of the toggle sections for generation of the pressing force are gradually expanded. Since the operational phases of the toggle sections are matched to each other, the toggle mechanism applies a uniform pressing force onto the movable platen.

Abstract: When the mold of plastic injection molding machine is locked, the closing force (K) is measured at the knuckle joint system during a predetermined number of operating cycles (Z). A mean value is computed from these actual value measurements (Si) and if it is within a predetermined tolerance zone (T) around a set-point value (So), no control intervention takes place. But if this mean value is outside of the tolerance zone (T) but in a control zone (R) limited by alarm limits (A), a control intervention takes place by stepwise changing the installed height of the mold until the actual value measured after each operating cycle is again within the tolerance zone (T). The measurement is repeated over another operating period (B); if those measurements stay within the control zone (R), a new mean value is computed only at the end of this operating period and a corresponding decision is made whether or not a control intervention should take place.
Abstract translation: 当塑料注射成型机的模具被锁定时，在预定数量的操作循环（Z）期间，在转向节接头系统处测量闭合力（K）。 从这些实际值测量（Si）计算平均值，并且如果它在设定点值（So）周围的预定公差区域（T）内，则不进行控制干预。 但是如果这个平均值超出公差范围（T），但是在由报警极限（A）限制的控制区域（R）中，则通过逐步改变模具的安装高度来进行控制干预，直到实际测量的值达到 每个操作周期再次在公差范围（T）内。 在另一个操作周期（B）重复测量; 如果这些测量值保持在控制区域（R）内，则仅在该操作期间结束时计算新的平均值，并且作出相应的决定是否应该进行控制干预。

Abstract: A machine for injection molding or die casting includes a main machine base with an injection unit mounted on the rear face and a mold guideway mounted on the front face. An aperture in the main machine base and a corresponding one in the base of the guideway provides for the nozzle of the injection unit to engage molds carried in the guideway. The reciprocating of the molds toward and away from one another is due to the action of a totally enclosed toggle assembly interconnecting mold-carrying shanks with compression lever brackets mounted in the ends of the guideway, actuators being located centrally of guideway ends and linked to the toggle assembly. Position adjusters are incorporated for adjusting the location of the injection unit on the rear of the machine to position its nozzle relative to the molds.
