[0002] The traditional hinged clamping mechanism obtains the clamping force by amplifying the force generated by the straightening of the hinge. It is difficult to control the magnitude of the clamping force, and it is also difficult to accurately set the clamping force as required. The power and demoulding force are generated by the amplification of the cylinder force. The larger the cylinder force required, the larger the diameter of the cylinder, and more power hydraulic oil is needed to participate in the rapid mold movement, resulting in high energy consumption; And the accumulation of processing tolerances of the templates makes the parallelism between the templates holding the molds not high, resulting in low machine precision. Due to the uneven force, the wear of the machine hinges is aggravated and there is no compensation device, which will further reduce the accuracy of the machine. Opening and closing the mold In order to overcome the moving frictional resistance of the movable template, especially the significant rotational frictional resistance generated by the steel sleeve in the hinge and the pin shaft under the load of the clamping force when the clamping force is generated, the steel sleeve in the hinge and the pin shaft have a A large amount of lubrication is required in the relatively rotating place, which will cause lubricating oil pollution to the machine. The uneven force of the clamping rod may cause the breakage of the clamping rod. The uneven force of the thread mold adjustment will easily lead to uneven mold adjustment or even thread burning. ;Traditional hydraulic direct press requires too much hydraulic oil to participate in the work, high energy consumption and low efficiency. If you want to improve efficiency, you need to improve the configuration, resulting in high cost; the traditional hydraulic two-platen machine has a long cycle and low efficiency due to many actions. The complex hydraulic control leads to insufficient machine stability; the deformation of the fixed platen of the traditional clamping mechanism cannot form self-compensation, which may easily lead to flashing of injection molded products
