INJECTION MOLDING MACHINE WITH VISCOSITY MEASURING FUNCTION AND METHOD FOR MEASURING VISCOSITY USING INJECTION MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine and a method for measuring viscosity which allow pressure measurement in a nozzle adapter to measure the viscosity of a resin injected through a nozzle which need not be replaced in association with a mold.;SOLUTION: A nozzle 2 is attached to a heating cylinder 1 via a nozzle adapter 60. Figure 2 is a diagram showing a pressure measurement position 64. When a sensor for pressure measurement is attached to the nozzle adapter 60 to measure the pressure, the sensor for pressure measurement need not be replaced in association with a mold 40 like the nozzle 2. A molten resin is injected into the air with a front of the nozzle open, and a resin pressure is measured by pressure measuring means while the molten resin is being injected into the air. On the basis of the measured resin pressure, the viscosity of the injected molten resin is determined.;COPYRIGHT: (C)2015,JPO&INPIT
