Environment-friendly plastic product injection molding process

Abstract

The invention relates to an environment-friendly plastic product injection molding process, which uses an environment-friendly plastic product injection molding device, the environment-friendly plastic product injection molding device comprises a bottom plate, an injection mold and an injection molding mechanism; the injection mold is arranged in the middle of the upper end surface of the bottom plate, and the injection molding mechanism is arranged above the middle of the injection mold; and the injection molding mechanism is installed on the bottom plate. The environment-friendly plastic product injection molding process provided by the invention can solve the problems that an existing environment-friendly plastic product injection molding device cannot achieve the effect that one mold can mold a plurality of columnar plastic products at the same time, the injection molding production efficiency is low, the length of a molding mold cavity cannot be adjusted according to the required length of the plastic products, and injection molding products are single; and the problems that a mold of the environment-friendly plastic product injection molding device is poor in sealing effect, required environment-friendly plastic liquid cannot be uniformly injected into a mold cavity, bubbles are generated on the surface of a molded product, and the product quality is influenced can also be solved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, and specifically proposes an injection molding process for environmentally friendly plastic products. Background technique [0002] Injection molding process refers to the process of making semi-finished parts of a certain shape from molten raw materials through operations such as pressurization, injection, cooling, and detachment. The injection molding process mainly includes the stages of mold closing, filling, pressure holding, cooling, mold opening, and demoulding. These 6 stages directly determine the molding quality of the product, and these 6 stages are a complete continuous process. Demolding is the last link in an injection molding cycle, but also the most important link. Although the product has been cold-set and formed, demoulding still has a very important impact on the quality of the product. Improper demoulding method may cause uneven force on the product during ...

AI Technical Summary

Problems solved by technology

The shape of the injection molding product corresponds to the mold one by one. Most of the existing injection molding devices adopt the injection molding form of one mold and one cavity, and the production efficiency is low. Therefore, an injection molding process of environmentally friendly plastic products is proposed to improve the efficiency of injection molding and product size. diversification

[0003] In the injection molding process of environmentally friendly plastic products, according to the injection molding process, it is necessary to design the mold and inject and fill the environmentally friendly plastic liquid: the existing injection molding devices for environmentally friendly plastic products have the following defects: 1. The existing environmentally friendly plastic products The injection molding device cannot realize that one mold can mold multiple cylindrical plastic products at the same time, the injection molding production efficiency is low, and the length of the molding cavity cannot be adjusted according to the length of the required plastic products, and the injection molding products are relatively simple; 2. The existing environmental protection The mold sealing effect of the plastic product injection molding device is poor, and the required environmentally friendly plastic liquid cannot be evenly injected into the mold cavity, resulting in bubbles appearing on the surface of the molded product, which affects product quality
