Anti-wear injection device for resin molding

Abstract

The invention discloses an anti-wear injection device for resin molding, which belongs to the field of resin molding, and is characterized in that a mold is effectively protected by additionally arranging an anti-wear treatment part on the basis of an existing injection molding machine, and resin passes through the anti-wear treatment part before being pushed into the mold; the annular finishing piece in the wear-reducing treatment piece firstly scrapes and finishes the outer surface of the viscous-flow-state resin, so that the exposed fiber reinforced body is wrapped, the wear to the mold is effectively reduced, the smoothness of the outer surface of the resin can be effectively improved under the cutting action of a scraper, and the service life of the mold is prolonged. The annular finishing piece is extruded by the resin while finishing the resin, and the magnetized rod piece and the oil releasing piece are sucked by utilizing the magnetization effect, so that the lubricating oil flows out and is adhered to the outer surface of the resin, the abrasion of the mold is further reduced by reducing the frictional resistance, the service life of the mold is effectively prolonged, and the lubricating oil is convenient for demolding. The problem that the release agent cannot be sprayed at the corner of the grinding tool is effectively solved.

Description

technical field [0001] The invention relates to the field of resin molding, and more specifically relates to an anti-wear injection device for resin molding. Background technique [0002] Resin usually refers to an organic polymer that softens or melts after being heated, has a tendency to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad definition, any polymer compound that can be used as a raw material for plastic products is called a resin. Reinforced resin components contain high-strength fibers and other reinforcing materials, which make some plastics whose mechanical properties are greatly improved compared with the original resin. It is also a polymer composite material. Depending on the resin used, there are thermoplastic reinforced plastics and thermosetting reinforced plastics. The reinforcing materials used are mostly glass fiber, carbon fiber, polyaramid fiber, asbestos fiber, ceramic fiber ...

AI Technical Summary

Problems solved by technology

[0004] The current injection molding equipment mainly includes an injection molding machine and a closed mold. The existing molding machine can fully handle the injection of a single resin raw material, but for the resin with fiber reinforcement, the length of the pellets used is less than 7mm , so when the fiber reinforcement exceeds this length, it will cause greater wear to the mold and seriously reduce the service life of the mold
