ABSTRACT:
An injection nozzle plugging rod (4) of machines for molding plastic material containers, provided with a locking system suitable for preventing the separation of the parts forming the actuating pneumatic piston of the same rod, said piston being subjected to considerable stresses during the machine operation. Thus, the rod according to the invention is able to prevent the piston binding, and therefore also the locking of the same rod, considerably reducing the number of maintenance interventions and thus increasing the throughput of the molding machine.
