The utility model aims to provide a tire mold capable of limiting the surface pressure acting on an end face of an internal mold assembly and simply and conveniently coping with the change based on repeated use. A solution method of the tire mold is as follows: a fan-shaped body constituting an annular tread mold part comprises internal mold assemblies and back mold assemblies, wherein the internal mold assembly are contacted with a tread and are mounted at the inner peripheral sides of the back mold assemblies; gaskets are arranged between the end faces of adjacent back mold assemblies in the peripheral direction, are freely mounted and dismounted relative to the end faces of the back mold assemblies and protrude towards the peripheral direction from the end faces of the gaskets. According to the tire mold, when the mold assembling is carried out by connecting the fan-shaped body in the peripheral direction when the mold tire in a vulcanization forming process at a heating state, gasket-based gaps are formed between the end faces of adjacent back mold assemblies in the peripheral direction, and the end faces of the adjacent internal mold assemblies are abutted with one another. |
