Anti-clogging impurity removal exhaust injection plastic cylinder

Abstract

The invention discloses an anti-blocking impurity-removal, exhaust and injection-moulding material barrel. A boss is arranged on the inner wall of a feeding cylinder (1), the edge of the top end of an impurity removal device (3) extends outward to form a convex surface; the impurity removal device (3) is supported, clamped and arranged on the boss on the inner wall of the feeding cylinder (1) by virtue of the convex surface; the side wall of the impurity removal device (3) is of an internal cavity structure, and a magnet is arranged in a cavity; an exhaust through hole (401) is formed in the side wall of the feeding cylinder (1), an exhaust cover (402) is arranged on the exhaust through hole (401), the exhaust cover (402) is connected with a side wall shaft of the feeding cylinder (1), the exhaust cover (402) is arranged on the outer surface of the side wall of the feeding cylinder (1); a thread-like cooling water pipe is arranged on the outer surface of a discharging cylinder (2). The anti-blocking impurity-removal, exhaust and injection-moulding material barrel can conveniently remove scrap iron impurities and is easy to clean, and a discharging hole is not blocked; meanwhile, impurities in the material barrel can be timely discharged without adopting other equipment, so that the anti-blocking impurity-removal, exhaust and injection-moulding material barrel is easy to use.

Description

technical field [0001] The invention relates to the field of injection molding machinery, in particular to an impurity-removing exhaust gas injection molding feed cylinder. Background technique [0002] In the injection molding industry, the barrel is used to store clinker particles and wait for heating for injection molding. Since the particles in the barrel enter the heating screw of the injection molding machine, they are heated by the rotation of the heating screw to melt the clinker particles, and then the heating screw injects the molten plastic. In the mold cavity, when there are iron filings impurities in the clinker particles, it will not only affect the quality of the injection molding product, but also, if the plastic is mixed with iron filings, the barrel screw will be stuck, which will cause grinding and wear, resulting in equipment damage , At the same time, if there is gas entering the mold cavity, the injection molded product is prone to produce air bubbles, ...

AI Technical Summary

Problems solved by technology

However, after the iron filings are adsorbed by the magnet frame, it is easy to block the feed inlet, resulting in insufficient feed, resulting in empty heating of the heating screw, causing safety problems
