Problems solved by technology

When adjusting the clamping force, the arms of the elbow must be consistent, even if there is a slight difference in length, it will cause uneven force on the template, thus causing the mold to deflect
Therefore, it is troublesome to adjust the mold and easy to wear and tear.

Abstract

The invention discloses a connection rod mechanism of a mold clamping apparatus. Two same sets of connection rods are arranged symmetrically up and down. Each set of connection rods comprises a first small connection rod, a second small connection rod, a first rear connection rod, a second rear connection rod, a middle rear connection rod, a first front connection rod, and a second front connection rod. The middle rear connection rod is positioned between the first rear connection rod and the second rear connection rod. The rear ends of the three connection rods are hinged to a first connection rod support. The rear end of the first front connection rod is clamped between the front ends of the first rear connection rod and the middle rear connection rod, and is hinged therewith. The second front connection rod is arranged between the front ends of the middle rear connection rod and the second rear connection rod, and is hinged therewith. The front ends of the two connection rods are respectively hinged with a second connection rod support. The first small connection rod is parallel to the second small connection rod. One end of the small connection rods is hinged with the middle rear connection rod, and the other end is hinged to a crosshead. The connection rod mechanism provided by the invention is advantaged in stable structure and good twisting force resistance. Therefore, a technical difficulty of complicated mold adjusting of prior arts is solved.

Description

technical field [0001] The invention relates to a connecting rod mechanism of a mold clamping device, in particular to a connecting rod mechanism of a mold clamping device of an injection molding machine, and belongs to the field of mechanical design. Background technique [0002] The mold clamping part is one of the important parts of the injection molding machine. Its function is to realize the opening and closing movement, so that the elastic deformation of the mold closing system can achieve the clamping force and lock the mold. [0003] At present, small and medium-sized injection molding machines mostly use double toggle clamping devices, such as figure 1 , the action principle of this form is: when opening and closing the mold, the clamping cylinder 1 enters the oil, and the piston rod pushes the double toggle linkage mechanism 5 to drive the movable template 6 and its mold to realize the mold opening and closing movement; when the mold contacts, the toggle The conne...
