Abstract
A device for rapidly disassembling an extractor unit from the driving mechanism of a press for vulcanizing pneumatic tires is positioned on the lower part of the open vulcanizing mould, while the extractor unit comprises a body of a substantially annular shape apt to be fixed to a mobile shaft of the vulcanizing press through first connecting means comprising a first set of radial teeth obtained on said shaft and a second set of radial teeth obtained on said body and able to cooperate with said teeth of the first set to block the body with respect to the shaft in consequence of a rotation of the former with respect to the latter; the device comprises also dragging means including a disc which rotates in consequence of the action of a lever, hand operated, said disc is provided with a plurality of stakes whose axis is parallel to the axis of said body, said dragging means being able to cooperate with said extractor unit so that said stakes are inserted into holes of said body to make this latter rotate with respect to said first shaft in consequence of the rotation of said disc so as to release said second set of teeth from said first set of teeth and to separate said extractor unit from said shaft.
