Rubber injection machine balance injection structure

Abstract

A balanced injection structure for a rubber injection machine, comprising an upright injection barrel connected to a plasticizing part, with an injection plunger head in transmission connection with an injection cylinder, a nozzle body at the lower end, and an injection cylinder with a There are more than two, which are evenly distributed on the side of the injection barrel, and the piston rod of the injection cylinder is connected with the transmission plunger head of the injection cylinder. The injection part of the present invention is placed vertically, but the injection cylinder and the injection barrel are arranged in a plane and parallel, so that the height of the whole machine is reduced; the plasticizing part and the injection part are independent, the temperature control of the plasticizing and injection parts is easy to control, and the nozzle opening is reduced The amount of vulcanization of the rubber material, and the cleaning of the rubber material is convenient; at the same time, there are more than two injection cylinders, which are evenly distributed on the side of the injection barrel, and the piston rod is connected to the injection plunger head of the injection barrel through a beam. When injecting, the piston rod retracts and pulls the crossbeam; the crossbeam pushes the injection plunger head, and the injection plunger head pushes the rubber to be injected through the inner flow channel of the nozzle body.

Description

technical field [0001] The invention relates to a rubber injection molding machine, in particular to a balanced injection structure of the rubber injection machine. Background technique [0002] The injection devices of several traditional rubber injection machines are: 1. The plasticizing barrel and the injection cylinder are at 90 degrees, single-cylinder injection, and the injection cylinder and the injection barrel are 180 degrees on a straight line; 2. The plasticizing barrel and the injection cylinder The oil cylinder forms a 180-degree single injection cylinder; 3. The plasticizing cylinder and the injection cylinder are on one side, and the plasticizing part is installed in the injection cylinder, and the method of double injection cylinders; 4. The double-cylinder horizontal injection structure, the plasticizing part It is arranged 180 degrees with the injection barrel, and two injection cylinders are installed horizontally on both sides. [0003] The disadvantage ...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the first structure is: the height of the whole machine is too high, which is not conducive to the installation of low workshops;

[0004] The disadvantage of the second structure is: because the weight deviation between the injection cylinder and the plasticizing part is too large, the lifting action of the injection platform cannot be performed, and the rubber at the nozzle port is easy to vulcanize;

[0005] The disadvantage of the third structure is: because the plasticizing and injection parts are on one side, and the plasticizing part is installed inside the injection part, it is not convenient to control the temperature of the rubber material, and the accuracy of the injection volume is not as high as the first two.

[0006] The disadvantage of the fourth structure is: because the injection barrel is placed horizontally, its flow path is 90 degrees to the nozzle body, the pressure loss of the rubber material is large during injection, and it is only suitable for the rubber material with low Mooney viscosity.

The structure is complex and the height of the whole machine is high, which is not conducive to the installation of low-level workshops
