Abstract:
1. A segmented mold for molding and vulcanizing a tire of given diameter (D S ), comprising shells and segments collaborating to withstand internal pressure during molding and to remain in a closed position without assistance from additional components, wherein each segment comprises its lateral edges at which a projection extends radially inwards, which projection is equipped with a lip extending axially towards an inside of the mold and having a frustoconical surface inclined at an angle α with respect to an axis (XX′) of the mold such that extensions of the line of each frustoconical surface on a meridian plane intersect on a radially internal side of a respective segment, and wherein each shell comprises a projection extending radially outwards and provided with a lip having a frustoconical surface inclined by the same angle α with respect to the axis XX′ of the mold, wherein the mold further comprises force-limiting means made up of a stop and of a housing positioned respectively in the radial extension of each of the projections and each having a bearing surface, the bearing surfaces adapted to come into contact with one another when the internal pressure in the mold exceeds a given threshold.
