Description

TECHNICAL FIELD

[0002] The statements herein are provided only to complement the background of the present application and are not necessarily indicative of the prior art.

[0003] In order to reduce production cost, tire factories often inlay character blocks on tire molds, and different tires meeting needs can be produced by replacing the character blocks.

[0004] At present, the more popular character block inlaying methods on the market are front screw fixing, back screw fixing or using a one-time character block on a cavity surface. The replacement efficiency of the above two character block inlaying methods is relatively low, especially the back screw fixing method, which needs to first disassemble the side plate from the mold shell before disassembling the character block. Meanwhile, the front screw fixing method generally uses screws to fix from the outer surface of the character block, and the outer surface of the character block will inevitably have screw holes for the screws to pass through, which will finally leave a screw head or screw hole mark on the vulcanized tire, affecting the appearance. The one-time character block made of aluminum material is used for the character block that is frequently replaced, and the destructive disassembly method is used to disassemble the old block and install the new block to reduce disassembly time, which undoubtedly causes waste of resources.
