INJECTION MOLDING SHOOTING POT ASSEMBLY, METHOD FOR CONTROLLING SHOT SIZE IN THE SAME ASSEMBLY, AND INJECTION MOLD

摘要

the invention of the injection molding shooting pot shot size control device coinjection nozzle having a coinjection hot runner on is adapted to be installed , the coinjection nozzle having at least two melt channels ending at the same gate is provided with a valve inlet and valve outlet . Preferably the form of an adjustable wedge mechanism is operated by hydraulic control the molten metal (40) is (i) a hot runner assembly 10 is disposed in the cavity plate 11 , near to set the shot size for the position which is the mold opening and , also ( ) wedge a shooting pot piston is filled when pulled from the shooting pot cylinder 23, 22 is configured to reduced pressure the molten metal .
