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.

摘要： A mould for the rotational moulding of manufactured articles of plastic material includes two half-moulds, one of which is provided, on its surface, with an insert-holding device comprising a rod with a first end passing through the wall of the half-mould at a respective passage channel and axially movable for projecting inside the mould. The mould also comprises a first pneumatic circuit able to apply a predetermined pressure, positive or negative, inside the mould. At least one insert-holding device is operatively connected to a second pneumatic circuit able to apply a predetermined pressure, positive or negative, and is internally provided with a plurality of means to apply the predetermined pressure at the passage channel, so that at the insert-holding device the same predetermined pressure value which generates inside the mould by the first pneumatic circuit is applied.
