Double-port discharging sleeve suitable for extrusion of easily-blocked molten plastic

Abstract

The invention discloses a double-port discharging sleeve suitable for extrusion of easily-blocked molten plastic, and relates to the technical field of injection molding equipment. The double-port discharging sleeve suitable for extrusion of the easily-blocked molten plastic can achieve continuous injection molding, is high in injection molding efficiency and can easily clean a blocked injection molding port. The double-port discharging sleeve suitable for extrusion of the easily-blocked molten plastic comprises a slotted circular sleeve, a double-port material blocking disc body, a feeding supply pipe, a discharging supply pipe, a double-port material blocking disc fixing mechanism, a waste cleaning mechanism, a waste hot melting mechanism and the like, wherein a circular through hole isformed in the slotted circular sleeve, the double-port material blocking disc body is rotationally installed in the slotted circular sleeve, and two circular through holes are formed in the double-port material blocking disc body. According to the double-port discharging sleeve, a rotating handle rotates to drive a meshing gear to rotate, so that a gear ring and the double-port material blocking disc body rotate; and the gear ring and the double-port material blocking disc body are matched with the double-port material blocking disc fixing mechanism to carry out position exchange and fixing onthe circular through holes of the double-port material blocking disc body, so that the two through holes are alternately used, and the injection efficiency of the molten plastic is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a double-port discharge sleeve suitable for extrusion of easily blocked molten plastic. Background technique [0002] The injection molding machine often stops running due to the blockage of the injection port during use, which makes it particularly important to ensure the smoothness of injection molding to improve the working efficiency of the injection molding machine. To ensure the smoothness of injection molding, it is necessary to control the feeding speed so that the molten plastic will not It is easy to solidify, and the clogged injection port needs to be cleaned in time to keep the injection smooth. [0003] The patent announcement number is: CN20717004 patent discloses a double-injection port injection molding machine, and its technical solution is: when using this device for injection molding, the main injection port at the end of the injection gun o...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the limited use times of the two injection ports, when both the main injection port and the auxiliary injection port are blocked, the injection work needs to be stopped to dredge the injection port, which makes the injection efficiency low and the cleaning of the injection port is difficult to affect the work efficiency. Technical problems: Provides a double-port discharge sleeve suitable for extrusion of easily clogged molten plastics capable of continuous injection molding, high injection molding efficiency and easy cleaning of clogged injection molding ports
