Embodiment Construction

[0036] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The action of unlocking and locking the mold of the injection molding machine will now be described in conjunction with accompanying drawings 1 , 2 , 3 , and 4 .

[0037] When performing mold clamping (see Figure 2), when the mold clamping cylinder 1 enters the mold clamping action, the crosshead 5 is pushed forward, and the short toggle lever 4 pushes the auxiliary toggle lever 3 and the middle toggle lever 6 to the rear toggle lever 7 Stretch down, push the front toggle 8, thereby pushing the movable template 9 to move forward, and realize the action of linear high-pressure mold clamping, see the schematic diagram of the action completion in Figure 3.

[0038] 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 toggle 7, thereby Make the fr...

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 clampingThe 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 combinemechanism 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 withs 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 acca 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 roording 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 hd 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 tigh-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.he 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. A composite mold clamping mechanism and a mold clamping 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 restricte...
