Abstract
Segmented mold for molding and vulcanizing a tire of given diameter, having shells and segments collaborating to withstand the internal pressure and remain in the closed position without assistance from additional components, having at its lateral edges a projection extending radially inwards, equipped with a lip extending axially towards the inside of the mold, having a frustoconical surface inclined at an angle α wherein extensions of the line of each frustoconical surface intersect on the radially internal side of the segment, each shell having a projection extending radially outwards and a lip having a frustoconical surface inclined by the same angle α, and containing force-limiting element having a stop and a housing positioned respectively in the radial extension of each of the projections and each having a bearing surface, to come into contact with one another when internal pressure in the mold exceeds a given threshold.
