Device for injection molding of high polymer material

Abstract

The invention discloses a device for injection molding of a high polymer material. The device comprises a crushing box, a fusion box and a stirring heating frame. A cavity is formed in the fusion box.A heating layer is arranged at the position, around the cavity, of the fusion box. Resistance wires distributed in an array manner are arranged in the heating layer. The crushing box is arranged at the upper end of the fusion box. Three through pipes distributed at equal distances are arranged at the lower end of the crushing box. The stirring heating frame is inserted into the fusion box in a penetrating manner and provided with a rotating shaft. A first rotating shaft inner cavity and a second rotating shaft inner cavity are arranged in the rotating shaft. Stirring rods distributed in an array manner are arranged on the rotating shaft. A stirring rod outer cavity and a stirring rod inner cavity are arranged in each stirring rod. According to the device for injection molding of the highpolymer material, heating is uniform and comprehensive, the high polymer material is not prone to adhering to a boiler, the fusion material of the high polymer material is high, and injection moldingis facilitated.

Description

technical field [0001] The invention relates to a molding and injection molding device for polymer materials, in particular to a device for molding and injection molding of polymer materials. Background technique [0002] Polymer materials are materials based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Polymers are the form of life. All living organisms can be regarded as a collection of macromolecules. The unique structure of polymer materials and the characteristics of easy modification and processing make them have incomparable and irreplaceable excellent properties of other materials, so they are widely used in various fields of science and technology, national defense construction and national economy, and have become a part of modern social life. Indispensable materials in all aspects of basic necessitie...

Problems solved by technology

[0003] Polymer material molding injection molding is to inject molten polymer material into a metal model under high temperature and high pressure, and obtain a plastic product with a certain shape after cooling. At present, the commonly used injection molding system polymer material is too large to melt before injection molding, which is not conducive to melting. , the current commonly used heating method is uneven heating, easy to stick to the wall, and the melting quality is low, which is not conducive to subsequent molding injection molding
