Temperature-adjustable pattern block and tire mold

The utility model discloses a temperature-adjustable pattern block. The invention belongs to the technical field of tire molds. The pattern block comprises a pattern block body, grooves are formed inone or more positions of the end face, the parting surface and the back face of the pattern block body, the grooves are formed in the circumferential direction and/or the axial direction of a patternring formed by the pattern block body, the grooves are hollow or filled with filling blocks, and the heat conductivity coefficient of the filling blocks is different from that of the pattern block body. Due to the fact that the grooves are formed in one or more positions of the end face, the parting surface and the back face of the pattern block body, the heat transfer rate of the end face, the parting surface and the back face of the pattern block body can be effectively changed, the vulcanization temperature of a tire shoulder and a tire tread of a tire can be adjusted, and the over-vulcanization condition is avoided
