Injection molding method of plastic bolt

Abstract

The invention discloses an injection molding method of a plastic bolt. The method comprises the following steps that plastic bolt raw materials and an auxiliary agent are subjected to hot-melt mixingto obtain an injection solution; the injection solution is placed into a container after being filtered twice through a filter screen, and the temperature of the container is gradually reduced to enable the surface of the injection solution to be solidified; the injection solution is extruded through a mechanical arm till bubbles in the injection solution are extruded; the extruded injection solution is poured into a mold till the mold is full, and then the formed mold is obtained through an extruding machine; the formed bolt is solidified and demolded, and a qualified finished product is obtained after testing; and after crushing, an unqualified product is changed into the raw materials, and the steps 1-5 are repeated.

Description

technical field [0001] The invention belongs to the field of plastic processing, and in particular relates to an injection molding method of plastic bolts. Background technique [0002] In the prior art, the molding of injection molded parts mostly depends on the injection molding machine, but mechanical processing often loses flexibility, and there are always many unavoidable mistakes in the processing process, which makes the finished injection molded parts have certain defects, and the injection molding machine is usually In mass production, there are too many defective products, which greatly increases the production cost. [0003] In order to improve the finished product quality of injection-molded bolts and effectively recycle defective products, a new manufacturing method for plastic bolts is needed. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an injection molding method ...
