摘要： A closing device for a mold group with two half-molds extends along a main axis and has a device body mountable to one of the two half-molds, and a closing group having a closing element rotatable about a rotation axis between a closing position, in which the two half-molds are lockable and an opening position, in which the two half-molds are releasable. A movement group housed in the device body and engaged with the closing group to rotationally move the closing element has a stem movable along the main axis and transmission members for transforming linear motion of the stem into rotatory motion of the closing element. A command group has a command plate engaged with one command end of the stem and a metal sealing bellows engaged with the command plate. A position of the metal sealing bellows corresponds to an axial position of the command plate and of the stem.
