Title:
INJECTION MOLDING MACHINE VALVE GATE NOZZLE
Document Type and Number:
WIPO Patent Application WO2000043187
Kind Code:
A8
Abstract:
An injection molding machine valve gate nozzle (25) having a rack driven valve pin actuator (65) for moving a valve pin (50) between open and closed positions during each holding cycle of operation. The valve pin actuator is sealed from the fluid flow stream and the nozzle body has a valve pin guide (52) which substantially separates the melt stream from the valve pin during passage through the nozzle for enhanced long-term operation. The actuator has a modular construction which lends itself to economical manufacture and efficient use in multiple drop or single molding machines without modification.
