Abstract
A valve pin actuator for an injection molding system includes a housing defining a chamber, the chamber having a nozzle opening portion and a nozzle closing portion. A piston is axially slideable within the chamber between a nozzle open position and a nozzle close position. The piston secures a valve pin to translate axial movements of the piston into axial movements of the pin. The nozzle opening portion of the chamber is configured to receive a first fluid to pressurize the nozzle opening portion to urge the piston towards the nozzle open position. The nozzle closing portion of the chamber is configured to receive a second fluid to pressurize the nozzle closing portion to urge the piston towards the nozzle close position. A fluid passage defined by the piston allows fluid communication between the nozzle opening portion and the nozzle closing portion.
