Technical Field

[0001] The present invention relates to the field of mold technology, in particular to a molding mold for speaker accessories. Background Art

[0002] With the development of society and the continuous improvement of living standards, the use of speakers has become more and more widespread. The speaker is the terminal of the entire audio 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 audio system, responsible for converting electrical signals into sound signals for people to listen directly to. The cabinet components of traditional speakers are mostly made of a common plastic material, and plastic components are usually manufactured by injection molding or hot pressing.

[0003] Existing hot pressing forming is a forming processing method in which an external force is applied to a plate through a mold to cause it to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. However, during the hot pressing process, the plate needs to be delivered cyclically. Due to the pressure of the hot pressing, each plate needs to be manually adjusted and straightened before being delivered and placed. Moreover, the delivery distance is affected by human perception. If the placement distance deviates, the plate cannot be positioned stably and effectively, which is not conducive to the hot pressing of the plate. The quality of the formed parts is unstable and the scope of application is small.
