Injection molding mechanism with high injection capacity

Abstract

The invention relates to an injection molding mechanism with high injection capacity, which comprises a primary plunger cylinder consisting of injection function modules and also comprises at least one secondary plunger cylinder consisting of injection function modules, wherein the injection function modules supply injection power via a single cylinder; a hydraulic sealing nozzle is arranged at the head of the primary plunger cylinder; and the primary and secondary plunger cylinders are communicated via a one-way valve. The injection molding mechanism in the invention is applied to a super-large plastic injection molding mechanism, has super-high injection capacity and can reduce the structural sizes of parts and units, so processing and production of parts and units are carried out smoothly and cost is reduced.

Description

technical field [0001] The invention relates to a type of injection molding machine, in particular to a type of injection platform structure of an injection molding machine which needs a large plastic injection molding mechanism to complete high injection volume. Background technique [0002] With the rapid development of injection molding technology, modern industries such as urban construction and municipal plumbing facilities have an increasing demand for products with larger dimensions, and the injection volume required for one molding process has also grown from a few kilograms to nearly a million. gram. The applicant's patent No. ZL 200720059325.2 discloses a screw plunger type plastic injection molding machine injection structure, but it still cannot meet the injection volume of a super large plastic injection molding machine. If the size of the mechanism is increased, Then the size of all supporting parts needs to be increased, such as thickening the screw, enlargin...

Problems solved by technology

The applicant's patent No. ZL 200720059325.2 discloses a screw plunger type plastic injection molding machine injection structure, but it still cannot meet the injection volume of a super large plastic injection molding machine. If the size of the mechanism is increased, The size of all supporting parts needs to be increased, such as thickening the screw, increasing the size of the melt motor, etc. The processing of large parts is difficult and costly, resulting in the high cost of the entire equipment

Among them, the head of the plunger cylinder is equipped with reversing shaft, rocker arm, rotary valve cylinder body, rotary valve body, material channel connecting pipe, nozzle and other components to realize the opening and closing function of the material channel, which has the disadvantages of complex structure and so on.

In response to the development of the current industrial demand, the current structural design can no longer meet the needs of the development of the plastic molding industry, it is necessary to develop an injection platform structure that can provide higher injection volume injection molding machines
