Mold device for producing horn disc body and production method applying mold device

Abstract

The invention relates to a mold device for producing a horn disc body and a production method applying the mold device. The mold device comprises a lower die holder, a lower die core, an upper die holder, an upper die core, a positioning die sleeve and a driving mechanism. The lower die holder is arranged below the driving mechanism, the lower die core is arranged on the lower die holder, the positioning die sleeve sleeves the lower die core, the upper die core is connected to the upper die holder, the upper die holder is arranged on the driving mechanism and is in drive connection with the driving mechanism so that the upper die holder can move vertically through the driving mechanism and can rotate around the center line of the upper die core. The invention further provides a productionmethod applying the mold device. The mold device for producing the horn disc body has the advantages of being simple in structure, high in reliability, high in machining efficiency, good in machiningquality and the like; the production method applying the mold device can effectively lower the operation difficulty of operation workers and improve the machining efficiency and quality of the horn disc body, and the yield of horn disc bodies manufactured through the production method is quite high.

Description

technical field [0001] The invention relates to the technical field of speaker production, in particular to a mold device and a production method for producing a speaker basin. Background technique [0002] At present, horn basins are mostly formed by placing self-condensing fluid materials in a mold and extruding them into shape. Wherein the existing mold is only composed of a punch and a die, and the punch has only linear motion relative to the die. During processing, the fluid raw material is first placed in the die, and then the worker manually distributes the fluid raw material in the die; then the punch acts on the die to form the fluid raw material into the shape of the horn basin. After the fluid raw material is solidified, the trumpet basin body can be obtained. However, since the fluid raw material is evenly distributed on the die by hand, the operation is very time-consuming and labor-intensive, which will reduce the manufacturing efficiency of the horn basin. ...

AI Technical Summary

Problems solved by technology

However, since the fluid raw material is evenly distributed on the die by hand, the operation is very time-consuming and laborious, which will lead to a decrease in the manufacturing efficiency of the horn basin

Moreover, due to the characteristics of the fluid material itself, it is difficult to make the surface of the fluid material smooth by hand, and there are still unevenness on the surface.

In this way, after the punch and the die are closed, the gas in the concave position of the fluid raw material is difficult to discharge, which will easily lead to the deterioration of the forming quality of the horn basin, which in turn will lead to a decrease in the pass rate of the horn basin
