ABSTRACT:
The machine has a main structure which supports, so that they can rotate about a substantially vertical rotation axis, a lower plate for supporting a centrifugal molding die and an upper plate. The plates face each other on a substantially horizontal plane and are mutually movable in a direction parallel to the rotation axis in order to ensure closure of the mold or to allow removal of the mold. The plates are accommodated in a chamber which is delimited by walls connected to the main structure and has, on the front side of the machine, an opening for access to the die. The opening is closed by a movable cover connected to at least one of the side walls delimiting the chamber by a pair of connecting rods. Each connecting rod has one end pivoted to the cover and another end pivoted to the related side wall with substantially horizontal pivoting axes to allow an opening movement of the cover along a vertical upward component and along a horizontal component toward the rear side of the machine.
