Description

Technical Field

[0001] This utility model relates to the field of mold device technology, and in particular to a molding core structure for a walkie-talkie housing. Background Technology

[0002] In modern manufacturing, walkie-talkies are an important communication tool, and the production quality and efficiency of their casings directly affect the product's market competitiveness. The molding die, as a key tool in manufacturing walkie-talkie casings, plays a decisive role in its technological level.

[0003] In the core component system of walkie-talkie housing molding dies, the male mold core is a key part that determines the internal shape and dimensional accuracy of the plastic part. It mainly cooperates with the female mold core to form a complete cavity, directly contacting the molten plastic and participating in the cooling and solidification process. Its structural design must closely match the internal features of the walkie-talkie housing, such as mounting slots, clips, and holes, while also considering molding efficiency, demolding convenience, and mold life. Traditionally, the male mold core structure of walkie-talkie housings is mostly fixed and non-replaceable; each male mold core can only produce one model of walkie-talkie housing.

[0004] Because the core structure in the mold of traditional walkie-talkie housing is irreplaceable, multiple sets of different molds need to be prepared when producing different models of walkie-talkie housings. The mold cost is high, which is not conducive to cost control in small-batch production. Therefore, it is necessary to improve it. Utility Model Content
