Hopper fixing device of injection molding machine

Abstract

The invention discloses a hopper fixing device of an injection molding machine. The hopper fixing device comprises a feeding cylinder, a feeding box, a fixing assembly and a clamping assembly, wherein a connecting pipe is fixed at the upper end of the feeding box, the clamping assembly is arranged at the upper end of the connecting pipe, the feeding cylinder is fixed at the upper end of the clamping assembly, the feeding cylinder is detachably connected with the connecting pipe through the clamping assembly, and the fixing assembly is located outside the feeding cylinder, abuts against the outer wall of the feeding cylinder and surrounds the whole feeding cylinder in an annular structure. According to the invention, the fixing assembly is arranged, secondary damping is achieved, when the feeding cylinder tends to move in the moving direction of the injection device due to inertia, secondary buffering can be conducted on the feeding cylinder, movement of the feeding cylinder is reduced, the long-term stability of the feeding cylinder is guaranteed, traditional flange or screw connection is changed through feeding cylinder connection, shaking of the feeding cylinder can be reduced, the problem that the screw rusts after being fixed for a long time is solved, and the disassembly is convenient.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines, in particular to a hopper fixing device of an injection molding machine. Background technique [0002] Compared with metal, stone, and wood, plastic has the advantages of low cost and strong plasticity. Now it is widely used. The production of plastic products is developing rapidly all over the world. Among them, the production volume of many kinds of plastic products in China has always ranked first in the world. , my country's plastic machinery technology in the production of plastic products continues to improve, and the Chinese plastic machinery market has attracted more and more attention from foreign companies. The types of plastic machinery can be divided into extruders, injection molding machines and blow molding machines according to the processing technology. Large category, in which the injection molding machine is very widely used, the injection molding machine is a k...

Problems solved by technology

[0003] Chinese Patent Publication No. CN205219592U discloses an injection molding machine, which includes an injection device, an electrical control device, a mold clamping body, a hydraulic transmission device, a cooling device, and a manipulator, and a hopper is arranged above the injection device; however, the hopper of this injection molding machine and The injection device is generally connected by a flange. When the injection device stops moving, the hopper will tend to move along the direction of the injection device due to inertia. After long-term use, the flange connecting the hopper and the injection device is easy to loosen, resulting in The stability of the connection between devices is not good
