Description

Technical Field

[0001] The utility model relates to the technical field of audio processing molds, and particularly relates to an inclined ejector mold for audio processing. Background Technique

[0002] An audio refers to a device that can convert an audio signal into sound. Generally speaking, it means that there is a built-in power amplifier in the audio main body box or the subwoofer box, and after the audio signal is amplified, the sound is played back by the audio itself to make the sound louder.

[0003] Household audio is generally used for home sound playback. Its characteristics are that the sound quality is delicate and soft, the appearance is relatively delicate and beautiful, the sound pressure level of the sound playback is not too high, and the power it can withstand is relatively small. Most of the existing household audio includes an external box body and speakers, crossovers and other electronic components located inside the box. Most of them adopt a small-sized shell structure design. When a household audio is produced and processed, injection molding work needs to be carried out on the external shell. This working process requires the use of an injection molding mold. However, in the production process with certain specific audio structure requirements, protrusions need to be designed on the inner side of the audio. When designing the injection mold for these protrusion positions, it is not convenient to directly eject in the vertical direction, which affects the demolding efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an inclined ejector mold for audio processing to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An inclined ejector mold for audio processing, including a front mold core, a rear mold core is arranged below the front mold core. The front mold core and the rear mold core are designed with an adapted structure. A front mold core cavity is arranged on the outer surface of the front mold core, and a rear mold core cavity adapted to the front mold core cavity is arranged on the outer surface of the rear mold core. A rear mold insert pin is installed inside the back of the rear mold core, a rear mold insert is fixedly installed inside one side of the rear mold core, and inclined ejector parts are fixedly installed on both sides inside the rear mold core.

[0006] Preferably, a number of evenly distributed rear mold round ejector pins are installed on the back of the rear mold core, and a number of evenly distributed rear mold bushings are installed on the back of the rear mold core.

[0007] Preferably, the rear mold insert adopts a double-slope conical structure design. The conical slope on the bottom side of the rear mold insert is 1°, and the slope on the top side of the rear mold insert is 0.4°.

[0008] Preferably, an insert ejector pin hole is opened on the upper surface of the rear mold insert, an insert ejector pin is arranged inside the insert ejector pin hole, a number of evenly distributed insert bushing holes are opened on the rear mold insert, and insert bushings are installed inside the insert bushing holes.

[0009] Preferably, the lifter includes a lifter rod, and a lifter block is fixedly installed at the top end of the lifter rod. The lifter rod and the lifter block are integrally formed.

[0010] Preferably, the inclination angle of the lifter rod inside the rear mold core is 4°.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The lifter mold for audio processing of the present utility model is provided with a rear mold insert with a double-slope cone. During actual use, it can effectively improve the hardness and durability of the mold, prevent problems such as wear and deformation of the mold during use, thereby extending the service life of the mold;

[0013] At the same time, the excellent wear resistance of the rear mold insert can effectively reduce the wear degree of the mold surface, thereby reducing the number of mold repairs and repair costs, and improving the production efficiency of the mold;

[0014] Moreover, during actual use, the lifter rod of the present utility model can perform an oblique ejection operation on the formed audio housing, which can meet the mold production requirements of certain specific audio structures, improve the demolding efficiency. Through the 4° inclination angle design, it is suitable for oblique ejection of audio housings with protrusion structures on the inner side, effectively solving the technical problem that for some existing audio housings with protrusions designed on the inner side, when designing the injection mold, direct vertical ejection cannot be performed, affecting the demolding efficiency.
