Description

Technical Field

[0001] The utility model relates to the technical field of acoustic production moulds, in particular to a quick demoulding mould for acoustic production. Background Art

[0002] Speakers refer to a device that can convert audio signals into sound. In layman's terms, it refers to a power amplifier built into the speaker box or subwoofer box, which amplifies the audio signal and then plays it back by the speaker itself, making the sound louder.

[0003] The speaker is the terminal of the entire sound system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the sound system and is responsible for converting electrical signals into sound signals for direct human hearing.

[0004] The existing shaped speakers need to produce an external shell during production. Most of the speaker shells are formed using an inverted mold during production. However, the existing speaker shell mold is not convenient for overall demoulding after molding and cooling, so it takes a certain amount of time to manually demould, which reduces the overall production efficiency and affects the production speed.

[0035] Through the several rear mold dome pins 202 provided in the present utility model, the sound box shell products in the mold cavity can be ejected after cooling and forming inside the mold cavity, thereby effectively improving the demolding efficiency of the mold of the present utility model, having a demolding effect of rapid ejection. In actual use, there is no need for manual picking and demolding treatment, which can effectively improve the demolding effect of the mold, avoid damage caused by manual demolding, improve the product production quality, and speed up the demolding efficiency, ensuring the overall production speed of the sound box;

[0036] At the same time, in actual use, the combined use of the front mold insert pin 102 and the rear mold insert pin 203 can fill the plastic in the cavity fully by compressing the molten plastic material, so that the forming accuracy of the product is higher and the surface is smoother, improving the quality and appearance of the product;

[0037] At the same time, during the injection molding process, the front mold insert pin 102 and the rear mold insert pin 203 can avoid the direct impact of the molten plastic material flow, protect the mold, and extend the service life of the mold;

[0038] Finally, the front mold insert pin 102 and the rear mold insert pin 203 can effectively control the flow of the molten plastic, reduce the waste of plastic materials that may cause problems, and thus reduce the production cost.

[0039] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
