Streamlined injection molding method for automobile parts and preparation equipment of streamlined injection molding method

Abstract

The invention discloses a streamlined injection molding method for automobile parts. The streamlined injection molding method comprises the steps of batching, mixing and fusing, injecting and filling;pressure maintaining, cooling and demolding. A preparation method of the streamlined injection molding method is further included and comprises a matching bin, a mixing bin, an injection molding machine, a mold bin, a mold circulating chain, a mold tool, a water cooling chain, a heat recovery chain and a discharging bin. On one hand, continuous quantifying, mixing and injection molding are carried out, and the time of middle circulation is saved; meanwhile, the injection molding, pressure maintaining and cooling procedures are separated and can be carried out at the same time, and the production efficiency is greatly improved; and on the other hand, heat generated through injection molding is utilized for preheating the mold tool, the temperature difference between a mold and materials isreduced, the uniformity degree of material distribution is improved, and the product quality is high.

Description

technical field [0001] The invention belongs to the field of injection molding equipment and technology, in particular to a streamlined injection molding method for auto parts and its preparation equipment. Background technique [0002] In recent years, with the improvement of people's living standards, the number of automobile purchases in China has shown an explosive blowout. In response, the automobile manufacturing industry and its upstream and downstream industries have developed rapidly, and a large number of automobile manufacturing enterprises have emerged. While the quantity of demand has risen sharply, users have higher and higher requirements for the quality of automobiles. Only enterprises that stand at the double peak of production and quality can have sufficient competitiveness. [0003] Injection molding process is an indispensable production process in automobile production. It can be said that the production efficiency of injection molding equipment is relat...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the current injection molding processes have the problem of low production efficiency. The entire process is mixed with many intermediate flows, and only one batch of molds can be processed at the same time, which consumes a lot of time and has low output.

[0006] 2. Most of the current injection molding processes have the problem of uneven heating of the workpiece. Due to the large temperature difference between the mold tooling and the material during injection molding, problems such as center of gravity shift, large flatness, and even cracks are prone to occur, resulting in poor product quality.
