ABSTRACT:
A nozzle for injection molding of thermoplastic viscous fluid materials which includes a nozzle body having a bore to provide a flow path. One end of the nozzle body is adapted for viscous fluid connection with a sprue of an associated mold body, and the other end is adapted for viscous fluid connection with an end of an associated injection molding machine. The nozzle body includes within its bore, a shut-off valve non-viscous fluid pin housing assembly which is adapted for reciprocating movement in the nozzle body. The fluid pin housing has a tip portion and a non-viscous fluid passage formed in the housing and open at the tip portion and the other end of the non-viscous fluid passage communicating with an associated source of pressurized non-viscous fluid. An actuator is provided for reciprocating within the nozzle body of the shut-off valve fluid pin housing to an open or closed position controlling the flow of viscous plastic through the nozzle body. The fluid pin housing tip portion located in the non-viscous passage of the fluid pin housing having a fixed or adjustable non-viscous fluid pin. The shaping of the fluid pin tip in the non-viscous fluid passage outlet provides different fluid flow during discharge and later exhaust of non-viscous fluid.
