Description

Technical Field

[0001] The utility model belongs to the technical field of rubber tire flexible molds, in particular to a rubber flexible mold which is easy to replace. Background Art

[0002] Tire flexible molds are equipment for tire molding and vulcanization. The flexible molds used in vulcanizers are mostly split-flap type, but the flexible blocks that make up the mold are mostly fixed to the mold base by screws. When some modules are severely worn and need to be replaced, it is necessary to manually unscrew the screws of the flexible blocks one by one, and then fix the new flexible blocks with screws. This method not only requires manual repeated adjustments of the relative position between the flexible mold and the mounting bolts of the vulcanizer, which takes a lot of adjustment time and has a relatively low disassembly efficiency, but also easily poses a danger to the operator when the bolts are difficult to install.
