Abstract
A mold for the rotational molding of manufactured articles of plastic material includes two half-molds, 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-mold at a respective passage channel and axially movable for projecting inside the mold. The mold also comprises a first pneumatic circuit able to apply a predetermined pressure, positive or negative, inside the mold. 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 mold by the first pneumatic circuit is applied.
