Apparatus for molding and vulcanizau00c7u00e7o tire wheels of vehicles, and process for controlling a detachment of the sectors such as tires vulcanized in a mold to vulcanizau00c7u00e7o.In the manufacture of tyre, a vulcanization process and molding of pneumatic tires is accomplished with an apparatus including a mold for vulcanization (2) comprising: a pair of plates (4, 4 ') adapted to be moved close to each other; a plurality of sectors such as distribution Ibuu00eddos ring (7), the plates (4),4) and sectors (7) being mutually movable between an open condition in which are spaced to permit the loading of the tire to be worked and a closed condition in which they define a molding cavity having a geometrical configuration with the outer surface of the tire married To be obtained.The process comprises the steps of: loading the green tire in the mold; vulcanize the tire; opening the mould; exert an action of thrust radially outside on each sector mold (7).
