Title:
INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/1987/005854
Kind Code:
A1
Abstract:
An injection molding machine which enables the control of the flow rate and speed of molten resins injected from an injection nozzle without a time-lag after the detection of the position of an injection screw and makes possible the control of injection speeds with excellent responsiveness, rapidity, and high accuracy. One rotary nozzle valve (22) for controlling the flow rate of molten resins flowing from an injection screw (2) toward an injection nozzle (12) is provided between one injection screw (2) provided rotatably and movably in a forward and backward direction in a housing (1) and one injection nozzle (12) which is provided at the front end of the housing (1) and injects molten resins into a cavity (14) of a mold (13), where said rotary nozzle valve (22) controls the flow rate and speed of molten resins, cooperating with an injection speed control device and a pressure control device which are provided separately.
