Manufacturing method of composite type high polymer material sound box body and mould equipment

Abstract

The invention provides a manufacturing method of a composite type high polymer material sound box body, and further provides mould equipment. The manufacturing method comprises the steps of designing a model, completing a mould, mixing materials, injecting, performing vacuum forming, removing oil, opening holes, assembling, etc. The mould equipment comprises a sliding device and a turnover device. According to the manufacturing method, the steps of mixing the materials, injecting and assembling are performed in a vacuum environment, so that the interior of the resin sound box can be effectively prevented from producing gas; in the manufacturing method of a resin sound box, the same vacuum degree is adopted in the steps of injecting and assembling, so that the texture and the density of the whole sound box are kept the same, and the sealability between a back board and the box body is good. According to the mould equipment, with the adoption of the sliding device with a gear rack, the closing and locating accuracy of the mould is realized; the turnover device can turn over the mould vertically, so that unidirectional stress of the interior of a mould cavity is avoided; the cavity is further prevented from deforming; and the materials can be filled in the whole mould cavity quickly and uniformly.

Description

technical field [0001] The invention relates to the technical field of audio box production, in particular to a manufacturing method of a composite polymer material audio box and mold equipment used in the manufacturing process. Background technique [0002] In a set of audio products, the role of the speaker box is very important: 1) It can separate the sound radiation before and after the speaker to prevent them from interfering; 2) Damping the resonance of the speaker to reduce the nonlinear distortion of the sound and improve the transient Response; 3) Broaden the low-frequency sound reproduction performance of the speaker, and increase the sensitivity of low-frequency radiation to make the sound more beautiful and pleasant. [0003] A good audio cabinet has a great influence on the choice of materials and craftsmanship for its sound quality and appearance. Resin has been used in audio equipment as a new material, but due to the hardness and brittleness of the resin mat...
