Environmentally-friendly efficient recovery crusher for waste injection molded parts

Abstract

The invention relates to the technical field of waste injection molded part recovery, in particular to an environmentally-friendly efficient recovery crusher for waste injection molded parts. A firstshaft is driven by a drive motor to rotate to exert multiple effects that firstly, a second shaft is driven by transmission of bevel gears to rotate, so that a disc-shaped cam acts on a crushing basket, and cooperates with a piston barrel at the right side to make the crushing basket do reciprocating motion along a sliding rail, and therefore, the action region of a crushing tip is changed; secondly, a triangular cam is driven by a worm gear and a worm to rotate, and through functions of a roller and a first spring, the crushing tip is driven to vertically move to crush the injection molded parts in the crushing basket; thirdly, a spiral auger is also arranged on the inner section, located in a feed hopper, of the first shaft, and the waste injection molded parts firstly undergo the crushing action of the spiral auger when being put into the feed hopper, and then, fall into the crushing basket and are crushed; and fourthly, the outlet of a guide hopper is blocked by a baffle when the baffle is in an initial state, and during reciprocating motion of the crushing basket, the baffle moves along with the crushing basket to realize intermittent discharging.

Description

technical field [0001] The invention relates to the technical field of recycling waste injection molded parts, in particular to an environmentally friendly crusher for efficiently recycling waste injection molded parts. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. [0003] Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. An injection molding machine has two basic components: the injection unit and the clamping unit for melting and feeding the plastic into the mold. On the one ...

AI Technical Summary

Problems solved by technology

[0008] Injection molded parts are prone to various problems during the production process, such as shrinkage cavity, shrinkage, unsaturated mold, burr, weld line, silver wire, spray mark, burnt, warping deformation, cracking / breaking, and size out of tolerance And other common injection molding problems, resulting in finished products that cannot meet the factory requirements. Usually people focus on mold design, molding process control, product design and plastic materials to improve, and the defective products produced are usually directly discarded, resulting in a large waste of materials.
