Embodiment 1

[0038]The upper mold 1 and the lower mold 2 are compatible with each other, the bottom of the upper mold 1 is fixedly connected with a positioning rod 6 extending to the inside of the lower mold 2, and the inside of the lower mold 2 is provided with a hole with the same outer diameter as the positioning rod 6. The movable groove is provided with a movable groove equal to the outer diameter of the positioning rod 6 by setting the inside of the lower mold 2, which is convenient for the upper mold 1 and the lower mold 2 to quickly close the mold, and the bottom of the high-temperature-resistant shell 7 is fixedly connected with a support leg 8 , the number of supporting legs 8 is four, and they are equidistantly distributed at the four corners of the bottom of the high-temperature-resistant casing 7, and the ends of the four supporting legs 8 away from the high-temperature-resistant casing 7 are fixedly connected with a base 9, which is convenient for molding The mold 2 is support...

Embodiment 2

[0040] The inner top wall of the top plate 11 is provided with a demoulding device 3 for demoulding the upper mold 1, the demoulding device 3 includes a telescopic mechanism 12 and a connecting plate 13, and a telescopic mechanism 12 is fixedly installed on the inner top wall of the top plate 11 , the output end of the telescopic mechanism 12 is fixedly connected with a connection plate 13, the connection plate 13 is fixedly connected with the top of the upper mold 1, and the upper mold 1 on the side of the connection plate 13 is driven downward by the direction of the mold 2 by starting the telescopic mechanism 12 Move so that the bottom surface of the upper mold 1 is in close contact with the top surface of the lower mold 2, so that a closed state is reached between the upper mold 1 and the lower mold 2, and the telescopic mechanism 12 is activated to drive the side of the connecting plate 13 The upper mold 1 moves toward the telescopic mechanism 12, so that the bottom surfac...

Embodiment 3

[0042] The heat dissipation device 4 includes a cooling groove 14 and a cooling fan 15. The high temperature resistant shell 7 is provided with a cooling groove 14 near the base 9, and the base 9 is fixedly equipped with a cooling fan 15 near the cooling groove 14. The number of the cooling fans 15 is Two, by setting and starting the heat dissipation fan 15, the heat dissipated from the heat dissipation groove 14 is quickly dispersed, which effectively accelerates the heat dissipation speed of the lower mold 2, achieves the advantage of good heat dissipation effect, and solves the problem of poor heat dissipation effect and cooling effect of the mold , has seriously affected the production efficiency of the earphone housing. The exterior of the booster pump 17 is fixedly connected with a fixed ring 22 positioned on the outer wall of the high temperature resistant casing 7. By setting the external fixed connection of the booster pump 17, the fixed ring 22 is fixed. Effectively e...

Abstract

The invention relates to the technical field of earphone shell production, and discloses an earphone shell injection mould which comprises an upper section mould, a lower section mould and a cooling device, wherein the top of the upper section mould is provided with a demolding device used for demolding the upper section mould, and the bottom of the lower section mould is provided with a heat dissipating device used for heat dissipation of the lower section mould; and a cooling device for cooling the lower section mould is arranged on the outer surface of the lower section mould. According to the earphone shell injection mould and the injection molding process thereof, after the position between the upper section mould and the lower section mould is filled, a booster pump is started for pressurization, and cooling liquid in a cooling box is conveyed into a circulating cooling water pipe through a water supply pipe and a water conveying pipe via pressurization of the booster pump,thereby facilitating rapid cooling treatment to the outer surface of the lower section mould; then, the cooling liquid in the circulating cooling water pipe is conveyed into the cooling box for cooling through arrangement of a water inlet pipe, and cooling treatment to the cooling liquid in the circulating cooling water pipe is facilitated; and the advantage of a good cooling effect is achieved.

Description

technical field [0001] The invention relates to the technical field of earphone shell production, in particular to an injection mold for an earphone shell and an injection molding process thereof. 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. The earphones can be separated from the media player, and only one plug It can be connected, and 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. It is 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 players. [0003] The earphone shell is usually prod...
