Feed pretreatment device for injection molding machine

Abstract

The invention discloses a feed pretreatment device for an injection molding machine. The feed pretreatment device for the injection molding machine comprises a bottom plate (1), a box body (2) is arranged on the bottom plate, and a feed hopper (3) is arranged above the box body (2); the inner side walls of the box body (2) are provided with a plurality of iron-made guide plates (4) which are sequentially displaced from the top to the bottom, and scrap iron separating devices are correspondingly arranged on the iron-made guide plates (4); and a drying and heating device (6) is disposed, below the iron-made guide plates (4), on the bottom plate (1) and is used for drying and pre-heating injected plastic particles. The feed pretreatment device for the injection molding machine performs pretreatment for the feed of the injection molding machine and drying and preheating for the materials, therefore, the improvement of the efficiency is benefited and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machine feed material processing, in particular to an injection molding machine feed material pretreatment device. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material, commonly known as plastic or resin, and its composition and shape can be changed freely. [0003] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. [0004] Most of the common injection molding machines use plastic pellets directly into the feed inlet, and there are the following ...

AI Technical Summary

Problems solved by technology

[0005] 1. Unpretreated plastic particles need to be heated inside the injection molding machine before use, resulting in low work efficiency, and when a part of the plastic particles are heated, the remaining plastic particles can only be used outside the injection molding machine Waiting, thus wasting a certain amount of working time, resulting in unsatisfactory work efficiency and a certain loss of economic benefits;

[0006] 2. If loose plastic particles are exposed to the air, they are easy to get damp, and the chemical properties of plastic products made of damp plastic raw materials will be significantly reduced, thus affecting the quality of the products
