Description

A mold processing system for a speaker shell

technical field

The utility model relates to the technical field of sound box processing, in particular to a mold processing system for a sound box shell.

Background technique

At present, the reverse wrapping technology of the plastic edge is to use the pressure of the upper mold to make the plastic cover the wooden box, which will cause the surface of the plastic to be crushed during the pressing process, affecting the appearance, resulting in a decrease in the yield and processing efficiency.

Utility model content

The technical problem to be solved by the utility model is to provide a mold processing system for a sound box shell in view of the above-mentioned deficiencies in the prior art.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a mold processing system for a sound box shell, including a sound box main body, a sound box shell and a mold main body, and the main body of the mold is provided with a flange for wrapping the sound box shell around the sound box body flange forming part; and the forming part comprises a vertical forming part and a horizontal forming part, and an edge forming part is arranged between the vertical forming part and the horizontal forming part; the vertical forming part and the horizontal forming part are respectively connected with the sound box main body The two vertical sides of the flange are bonded together, and the edge forming part wraps the flange of the main body of the sound box to shape it.

In the above technical solution, the inner wall of the edging forming part is provided with an undercut that fits with the surface of the housing of the sound box.

In the above technical solution, the inner wall of the edging forming part is an arc surface.

In the above technical solution, the housing of the sound box is a plastic housing.

In the above technical solution, the wooden box main body of the sound box main body.

The beneficial effects of the utility model are: the overall structure of the mold processing system is simple, but it is very practical, and can effectively solve the problem of poor appearance caused by the previous shell processing, and improve the yield and processing efficiency.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a mold processing system for a speaker shell 2 includes a speaker body 1, a speaker shell 2, and a mold body 3, and the mold body 3 is provided with a forming part that wraps the speaker shell 2 with a flange 7 of the speaker body; And this forming part comprises vertical forming part 4 and horizontal forming part 5, is provided with hemming forming part 6 between vertical forming part 4 and horizontal forming part 5; Described vertical forming part 4 and horizontal forming part 5 are respectively connected with The two vertical sides of the flange 7 of the speaker main body are bonded together, and the wrapping forming part 6 wraps and shapes the flange 7 of the main body of the speaker.

Wherein, an undercut 8 that fits with the surface of the sound box casing 2 is provided on the inner wall of the edging forming part 6 . The undercut 8 can realize the positioning of the end of the sound box shell 2 by the mold body 3, and realize stretching and molding of the sound box shell 2.

Wherein, the inner wall of the hemming forming part 6 is an arc surface. Making the inner wall smooth can avoid the bad appearance of the speaker's plastic shell during the molding process.

Wherein, the speaker shell 2 is a plastic shell. The wooden box main body of the sound box main body 1. The plastic shell needs to be preheated and softened before being edged by the mold body 3 .

The above embodiments are only intended to illustrate rather than limit the utility model, so all equivalent changes or modifications made according to the method described in the scope of the patent application of the utility model are included in the scope of the patent application of the utility model.
