Embodiment Construction

[0037] The specific implementation mode is now combined with the attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 Describe the action of opening and locking the mold of the injection molding machine.

[0038] When model locking is performed (see figure 2 Middle), when the clamping cylinder 1 enters the mold clamping action, the crosshead 5 is pushed forward, and the short toggle 4 pushes the auxiliary toggle 3 and the middle toggle 6 to straighten the rear toggle 7 downwards, pushing the front toggle Rod 8, so as to push the movable template 9 to move forward to realize the action of linear high-pressure mold clamping, see the attached image 3 The schematic diagram of the completion of the action.

[0039] When performing mold opening, oil is fed from the other end of the clamping cylinder 1 to pull the crosshead 5 to move backward, the short toggle 4 causes the auxiliary toggle 3 to pull down, and the middle toggle 6 pulls up the rear tog...

Abstract

The invention relates to a clamping mechanism of an injection machine, in particular to a porous series double-toggle inside and outside turning composite clamping mechanism and a method. The clamping mechanism is designed aiming at the problems of nonuniform template stress and template moving speed and large impact force of the clamping mechanism of the prior injection machine field, and combines the advantages of a mechanical twisting locked mode and a hydraulic direct pressure locked mode. The design key point of the clamping mechanism is as follows: the clamping mechanism is provided with a plurality of rotating shaft hinge points respectively arranged at the intersections of an auxiliary toggle rod and an intermediate toggle rod as well as a rear toggle rod and a front toggle rod according to the number of hinge holes of the auxiliary toggle rod and the intermediate toggle rod, and is provided with 6, 7, 8 or more than 8 rotating shaft hinge points to lead the auxiliary toggle rod and the intermediate toggle rod as well as the rear toggle rod and the front toggle rod to from a straight line. The method is as follows: the intersections are formed into straight lines, and the high-pressure locked mode force is produced by inside and outside turning of toggles so as to achieve the purposes for quickly moving the modes, reasonably matching the mechanism rigidity, shortening the cylinder stroke and lowering the template weight. The invention is suitable for the development and the upgrading reconstruction of the precise injection machine.

Description

technical field [0001] The invention relates to a mold locking mechanism of an injection molding machine, which is a porous type series double toggle with inside out and inside out, which has a large mold moving stroke, fast mold moving speed, small mold clamping deformation of the template, uniform force on the mold, large force magnification, and more energy-saving operation. Compound clamping mechanism and method. Background technique [0002] At present, the double-toggle oblique clamping mechanism commonly used in the field of injection molding machines can be divided into four-hole type and five-hole type according to the number of joints. As the clamping force increases, the size and stroke of the general template must increase accordingly to meet the needs of the product. However, the increase ratio of the template size is usually smaller than the increase ratio of the stroke, and the stroke of the general double toggle mechanism is restricted by the template size. ...
