Abstract
The tire mold comprises lower 12 and upper portions 14 which are movable relative to one another between a close-together position for molding the tire and a distanced position for extracting said tire from the mold, and a plurality of central sectors 16 which are in axial contact with the lower 12 and upper portions 14 in their close-together molding position. For each sector 16, the mold comprises an upper member 22 for permanently coupling said sector to the upper portion 14, and a lower member 20 for temporarily coupling said sector to the lower portion 12, said coupling members 20, 22 being configured so as to obtain, during an axial distancing movement of the lower 12 and upper portions 14 from their close-together molding position, a radial displacement of said sector 16 toward the outside followed by an angular pivoting.
