Description

Horn openable edge sealing die

Technical Field

The utility model relates to a car loudspeaker field of making, in particular to car loudspeaker's banding mould.

Background

At present, after a chassis of a vehicle horn and a sounding component are combined, a sealing ring is needed to seal the chassis and the sounding component. However, because the speaker is provided with the plug, and the plug is relatively protruded, the speaker after combination needs to be manually placed on the edge sealing mold, in order to reduce manual operation, a group of molds is usually used for pressing to complete edge sealing operation at one time, so that the edge sealing operation needs to be completed by using relatively large pressure, but the metal hardness used by the speaker chassis is not high, so that the edge of the speaker chassis, which is in contact with the sounding component in the edge sealing process, is easily deformed due to too large edge sealing pressure, and finally the edge flatness, the attaching degree and the sealing property of the edge sealing between the chassis and the sounding component are not ideal.

The technical problem to be solved by the application is as follows: how to reduce manual operation in the process of sealing the edges of the vehicle horn chassis and the sounding component.
