Injection molding machine for earphone production

Abstract

The invention relates to the technical field of earphone production, in particular to an injection molding machine for earphone production. The injection molding machine for earphone production comprises an injection molding machine body provided with an anti-blocking device; an earphone shell discharging device is arranged inside the injection molding machine body; the anti-blocking device comprises a feeding tube arranged on the upper surface of the injection molding machine body; a plurality of annularly-distributed grooves are formed in the upper surface of the feeding tube at equal intervals; the earphone shell discharging device comprises a containing tube arranged inside the injection molding machine body; and a cavity is formed inside the containing tube. The injection molding machine for earphone production is simple in structure and convenient to use; through arrangement of the anti-blocking device, the problem that a conventional earphone shell injection molding machine cannot continue to work once being blocked is solved; and through arrangement of the earphone shell discharging device, the problem that in the process of producing earphone shells by the conventional earphone shell injection molding machine, the earphone shells are not conveyed in time to cause damage of the earphone shells on the lower portion is solved.

Description

technical field [0001] The invention relates to the technical field of earphone production, in particular to an injection molding machine for earphone production. Background technique [0002] Earphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Headphones are generally detachable from the media player and connected with a plug. There are earphone shells in the composition of the earphones, and the earphone shells are generally made of plastic materials. The production of the earphone shells requires the use of an injection molding machine. During the production of the earphone shells by the conventional earphone shell injection molding machine, all the earphone shells are stacked together. If it is squeezed, it will damage the earphone shell below. In addition, the conventional earphone shell injection molding machine has its feed port tightly wel...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an injection molding machine for earphone production to solve the problems of extrusion damage caused by stacking and placement of earphone shells produced by the conventional earphone shell injection molding machine in the above-mentioned background technology and the problem that once the feed port is blocked, it cannot be used.
