Micro-adjusting injection molding device for processing earphone connectors

Abstract

The invention discloses a micro-adjusting injection molding device for processing earphone connectors, and relates to the technical field of earphone connector injection molding. The micro-adjusting injection molding device for processing the earphone connectors comprises a bottom fixing plate, wherein an injection mold is fixedly installed at the upper end of the bottom fixing plate. According tothe device, when a cylindrical adjusting screw rotates, a moving bearing can move front and back on the outer circle of the cylindrical adjusting screw through the arrangement that the moving bearingis connected with the cylindrical adjusting screw in a threaded mode, the moving bearing moves to drive an annular moving sleeve to move, and the annular moving sleeve drives a ring-shaped limit sleeve to move front and back through a rectangular connecting rod to adjust the position of the ring-shaped limit sleeve, so that earphones corresponding to different lengths of metal plugs can adjust the supporting point position of the ring-shaped limit sleeve during injection molding, so as to ensure that the metal plugs are always kept in parallel states, the situation of tilting, affecting the production quality, when the metal plugs are connected to injection positions.

Description

technical field [0001] The invention relates to the technical field of injection molding of earphone connectors, in particular to a micro-adjustment injection molding device for processing earphone connectors. 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. The advantage is that you can listen to the audio alone without affecting others; it can also isolate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording studios, bars, travel, and sports. Earphones were originally used on telephones and radios, but with the popularity of portable electronic devices, earphones are mostly used in mobile phones, walkmans, radios, portable video games and digital audio playe...

AI Technical Summary

Problems solved by technology

[0004] At present, when the existing injection molding devices for earphone connectors on the market are in use, the metal connectors are exposed outside the injection molding position, and the exposed length of the metal connectors will vary depending on the earphone model. When the existing devices are in use, the connectors The support device cannot ensure that the metal joints are always kept in a parallel state, so that after the metal joints are injected, the metal joints will be inclined, which will affect the processing quality
