  • Injection nozzle plugging rod
    Patent number: 7942664
    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.
    Type: Grant

  • Injection system having a closing rod provided with a cleaning device
    Patent number: 7841856
    Abstract: Injection system with closing rod (2) provided with a cleaning device (6, 7, 8) suitable for removing the powder of molten plastic that builds up in the movement areas of the closing rod (2), in particular in the thrust bearing (3), during the normal operation of a molding machine. Advantageously the system according to the invention avoids the limitation of the piston stroke and the subsequent blockage with time and thus also the blockage of the closing rod, considerably reducing the number of maintenance operations and thus increasing the productivity of the molding machine.
