AI Technical Summary

Technical Problem

Existing injection molding machines do not filter the raw materials during feeding, causing impurities from the plastic raw materials to enter the injection molding machine, resulting in black spots or impurities on the surface of the product and affecting the quality of the finished plastic product.

Method used

The injection molding machine is equipped with a feeding assembly and a filtering assembly, including a plastic storage tank, a pump body, a conveying pipe, a filter box, and a feed hopper. Impurities are filtered through two-stage filter plates, and a spiral heating coil is installed on the inner wall of the feed hopper to preheat the raw material. It is used in conjunction with a horizontal injection molding machine.

Benefits of technology

It effectively removes impurities from raw materials, improves raw material purity, reduces the risk of wear on molds and injection molding machine screws, improves product quality, and reduces the main heating load on the injection molding machine through preheating, thus saving energy.

Abstract

The utility model relates to the technical field of injection molding machines, and discloses a plastic production injection molding machine which comprises a mounting frame, a fixing plate is fixedly mounted at the upper end of the mounting frame, a horizontal injection molding machine and a mold are fixedly mounted on the surface of the fixing plate, and a feeding assembly and a filtering assembly are fixedly mounted on the surface of the mounting frame. The feeding assembly comprises a plastic storage box fixedly mounted on the surface of the mounting frame, a conveying pipe is fixedly mounted on the plastic storage box through a pump body, the filtering assembly comprises a filtering box fixedly mounted at the top of the mounting frame and a feeding hopper at the top of the horizontal injection molding machine, the plastic storage box stores raw materials, and the pump body drives the conveying pipe to convey materials; the material conveying pipe penetrates through the filtering box, raw materials enter the feeding hopper after being subjected to two-stage filtering impurity removal and purification through the first filtering plate and the second filtering plate in the box, the spiral heating coil on the inner wall of the feeding hopper preheats and softens the raw materials, the main heating burden of the horizontal injection molding machine is relieved, the raw materials are plasticized more evenly, and the product quality is improved in cooperation with high-pressure injection of the horizontal injection molding machine.
