Description

Technical Field

[0001] The utility model relates to a manufacturing mold with a positioning structure, which is applied to the field of manufacturing molds. Background Art

[0002] Speaker molds are customized tools specifically used to produce speaker components, and they play a core role in the speaker manufacturing process. When designing speaker molds, the specific specifications, shapes, and materials used for each component of the speaker must be carefully considered to ensure that the quality and performance of the produced speakers meet the standards.

[0003] The existing speaker housing mold includes an upper housing and a lower housing. An upper mold core is arranged inside the upper housing, and a lower mold core is arranged inside the lower housing. An injection cavity is arranged between the upper mold core and the lower mold core. Liquid material is poured into the injection cavity through a pouring port at the top of the upper housing and solidified to form a speaker housing mold. However, there is no positioning structure between the existing upper mold core and the lower mold core, which may lead to the problem that the upper mold core and the lower mold core are not properly matched or reverse assembly occurs, resulting in the failure of the housing forming. Therefore, in view of the above problems, the utility model designs a manufacturing mold with a positioning structure. Summary of the Utility Model
