Title:
METHOD OF DETERMINING LOAD IN INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/1991/013745
Kind Code:
A1
Abstract:
A method of determining the load of plasticized synthetic resin injected and filled into a cavity of a mold from a cylinder of an injection molding machine, aiming at determining the load with high accuracy even on the side of the injection molding machine in a continuous molding process. Screw positional values, pressures and temperatures, which are observed in a state where the pressure of the resin discharged from the cylinder is held at a given value and a shut-off valve and a check valve are closed, are operated before and after the injecting and filling, to thereby determine the load.
