Anti-blocking sprayer for injection molding machine

Abstract

The invention relates to the technical field of injection molding, in particular to an anti-blocking sprayer for an injection molding machine. The anti-blocking sprayer comprises a sprayer, the sprayer communicates with a stirring groove, and a material conveying pipe communicates with the side wall of the stirring groove; the lower end of the sprayer shrinks inward to form a narrow port, an impurity outlet is formed in the side wall of the sprayer, the diameter of the impurity outlet is between the size of an opening of the upper end of the sprayer and the size of the narrow port of the lowerend of the sprayer, a first piston is pushed upward through a bulge, so that the first piston moves up, a controller controls a first electric telescopic rod to shrink, thus a baffle moves up, impurities are discharged from the impurity outlet, after the impurities are discharged, the pressure returns to normal, a spring pushes down the first piston to reset a stop rod, and thus particle impurities with large volume are prevented from blocking the sprayer; and after the injection, a second electric telescopic rod is started to drive a second piston to reciprocate up and down, thus residual materials are blown out from the sprayer, and the residual materials are prevented from blocking the sprayer.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an anti-clogging nozzle for an injection molding machine. Background technique [0002] Due to its corrosion resistance, no reaction with acid and alkali, and stable performance, plastic parts have replaced many metal parts in the field of equipment manufacturing. At the same time, plastic zero manufacturing costs are low, which greatly reduces production costs. [0003] When manufacturing plastic parts, it is necessary to use an injection molding machine to inject the raw materials of the plastic parts into the mold, and the plastic parts can be obtained after molding. In the prior art, the processing of plastic parts is carried out by mixing various plastic particles together and melting them together. Since the plastic raw materials contain impurities, the impurities are easy to be stuck in the nozzle, which causes a lot of inconvenience to the processing of plastic ...

AI Technical Summary

Problems solved by technology

In the prior art, the processing of plastic parts is carried out by mixing various plastic particles together and melting them together. Since the plastic raw materials contain impurities, the impurities are easy to be stuck in the nozzle, which causes a lot of inconvenience to the processing of plastic parts; at the same time, during processing After the parts are finished, because there are residual raw materials in the nozzle body, they are easy to solidify after the raw materials are cooled, resulting in the blockage of the nozzle body, which brings inconvenience to the subsequent processing of plastic parts
