Description

An earphone pin cutting machine

technical field

The utility model relates to the field of earphone parts processing, in particular to an earphone pin blanking machine.

Background technique

In the prior art, in the process of earphone production, the pins of the earphone generally need to be covered with several parts such as rings before molding. It can just be placed into the small holes of the set number of rings. The depth of the small holes can be set to facilitate the removal of the rings, and then put the rings together one by one manually, and then take out the rings that are set together. For the plastic injection molding workers, the workers put multiple sets of rings into the mold. The general mold is to place more than 16 ring parts, and then put the mold into the injection molding machine to inject plastic into the pins of the earphone strap. This kind of process is very labor-intensive, and the requirements are very meticulous, especially the molding workers need to take out the ring parts put on the plastic plate, because the small holes are very small, it is not easy to align, and the ring parts are easy to come out , it is easy to make mistakes in operation. Usually, in order to be more efficient, there are two molding workers in the injection molding process. One takes out the ring parts on the plastic plate and puts them into the mold, and then the other worker is responsible for putting the mold into the molding machine. Forming is labor-intensive and the efficiency is not high.
