Injection molding machine capable of solving problems of waste of injection molding liquid and incapability in adjustment of injection molding speed

Abstract

The invention relates to the technical field of injection molding, and discloses an injection molding machine capable of solving the problems of waste of injection molding liquid and incapability in adjustment of the injection molding speed. Through cooperative use of a special-shaped plate, a rotating roller, a first rotating shaft, a second rotating shaft, a pinion, an injection molding pipe, a first disc and a second disc, quantitative injection molding can be performed during injection molding, and waste caused by raw material overflow due to the fact that the injection molding amount cannot be controlled is avoided; through cooperative use of a threaded rod and a third rotating shaft, the injection molding speed can be automatically adjusted during injection molding, so that the injection molding speed is low in the initial stage of injection molding, the molding material can be inhibited from entering the air, and in the later stage of injection molding, in order to achieve the purposes that solidification of the molding material is not delayed and the molding material is filled into a mold, the working efficiency of injection molding is improved; and through cooperative use of a first gear, a special-shaped disc and a rotating rod, the two steps of quantitative injection molding and injection molding speed adjustment are linked, and therefore the linkage of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection molding machine which solves the waste of injection molding liquid and the inability to adjust the injection molding speed. Background technique [0002] As we all know, injection molding is used to produce various plastic products used in the toy industry, household appliance industry and household goods industry. Plastic products are more and more widely used in various fields due to their excellent performance. Various shapes require molds and injection molding. The process puts forward higher requirements [0003] In the process of injection molding, it is necessary to use the injection molding machine to transport granular thermoplastic resin as raw material into the heating cylinder, but the existing injection molding machine is relatively simple to set up, and quantitative injection molding cannot be guaranteed during the injection molding process. ...

AI Technical Summary

Problems solved by technology

[0003] In the process of injection molding, it is necessary to use the injection molding machine to transport granular thermoplastic resin as raw material into the heating cylinder, but the existing injection molding machine is relatively simple to set up, and quantitative injection molding cannot be guaranteed during the injection molding process

When the amount of injection molding is too much, it will cause overflow of raw materials, resulting in waste of raw materials, which is not in line with the value of energy conservation and environmental protection, and when the amount of injection molding is too small, it will have a negative impact on the processing quality of finished products

At the same time, in the process of injection molding, the injection speed has a great influence on the quality of the molded product, but the injection speed of the existing injection molding machine cannot be adjusted, so when the injection speed is too slow in the later stage, the solidification time of the raw materials will be affected

[0004] Aiming at the deficiencies of the prior art, the present invention provides an injection molding machine that solves the waste of injection molding liquid and the injection speed cannot be adjusted, which has the advantages of quantitative injection and changing the injection speed, and solves the problem that the existing injection molding device is relatively simple. It ensures quantitative injection molding when using the device for injection molding, reducing the waste of raw materials, and at the same time increases the injection speed from the later stage of injection molding, reduces the solidification time of raw materials, and improves the work efficiency of injection molding
