Injection molding raw materials pretreatment process

Abstract

The invention relates to an injection molding raw materials pretreatment process. The pretreatment process mainly comprises the following steps of material preparation, crushing operation, cleaning operation, drying treatment and hot melt injection molding, wherein involved injection molding materials crushing equipment comprises a bottom plate, a crushing device, a shredding device and a conveying device. The pretreatment process disclosed by the invention can solve the following problems when the injection molding raw materials are crushed and screened by the prior art: firstly, an existingcrushing device for the injection molding raw material cannot guarantee the crushing quality when the injection molding raw materials are crushed, a screening net can be blocked during screening, andmanual processing is troublesome, so that the crushing efficiency of the injection molding raw materials is reduced; and secondly, the existing crushing device for the injection molding raw materialsis complex in structure, complicated to operate in use and large in tearing tooth gaps inside the crushing device, so that the injection molding raw materials with small structures are difficult to becrushed into tiny particles, and according to the pretreatment process disclosed by the invention, crushing efficiency and quality of the injection molding raw materials can be improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a pretreatment process for injection molding raw materials. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Injection molding raw materials often need to be crushed and screened before use. [0003] However, the following problems exist in the crushing and screening of existing injection molding raw materials. a. The traditional crushing device for injection mo...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the crushing and screening of existing injection molding raw materials. a. The traditional crushing device for injection molding raw materials cannot guarantee the quality of crushing when crushing injection molding raw materials, and the screen will be blocked during screening, and it must be processed manually It is more troublesome, which reduces the efficiency of crushing injection molding raw materials; b, the existing crushing device for injection molding raw materials has a complex structure, and the operation is cumbersome when used. Tiny particles, and relying on shredding teeth to squeeze waste plastics to form particles has the problem of low efficiency and also reduces the quality of injection molding products, which can improve the efficiency and quality of injection molding raw materials crushing
