Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1-4, a film-coated bottle stopper vulcanizing mold comprises a lower template 10, wherein the lower template 10 is provided with a plurality of cavities 20, the cavities 20 are in a through hole structure, each cavity 20 comprises a first hole 21 located on the upper side surface of the lower template 10 and a second hole 22 located on the lower side surface, and through holes 23 are formed between the first hole 21 and the second hole 22 for communication; the first hole 21, the second hole 22 and the through hole 23 are coaxial, and by the structure, the core mold 30 can be placed in the first hole 21, and the fastener 40 penetrates through the second hole 22 and is screwed and fixed with the through hole 23 and the core mold 30 in a threaded manner, so that when different types of bottle stoppers are produced, only the corresponding core mold 30 needs to be replaced, the lower template 10 is universal, the inventory of the lower template 10 is reduced, and the production cost is reduced. In production, two sets of lower templates 10 can be prepared, one set is used for production, and the other set can be used for replacing the core mold 30 corresponding to the next batch of bottle stoppers for standby, so that the production efficiency is improved.
