摘要： A mold extruder for a tire with a highly electrically conductive ring and a manufacturing method using the same. The extruder solves the problem of static electricity caused by failure to discharge charges generated in a vehicle body, to the ground, but accumulating charges on the tire when a large amount of silica is used into the tread rubber composition of a tire. The mold extruding die for forming a conductive ring on the tread extrudes a cap tread, an under tread, and tread wings simultaneously, is installed to a head section of a mold extruder having a tri-extruder for extruding a tire tread, and includes a preform die, a final die, and a cassette. The extruding passages for the cap tread, the under tread, and the tread wings are formed by assembling the preform die, the final die, and the cassette. By designing a conductive ring passage for the extruding passage of the under tread to penetrate the extruding passage of the cap tread, the under tread rubber composition protrudes so as to divide a space of the cap tread extruding passage by the conductive ring passage penetrating the cap tread into a right-side space and a left-side space. For the purpose of easily protruding the under tread rubber composition to an upper end of the cap tread through the conductive ring passage, a triangular recess on a ceiling of the under tread extruding passage penetrates the cap tread extruding passage from a rear side to a front side is formed.
