Abstract
An injection molding machine and a viscosity measurement method of the disclosure are provided with an injection cylinder to which a viscosity measurement unit is attachable and detachable and a control device. When setting an inner diameter of the injection cylinder or an outer diameter of the injection shaft as D. For a capillary installed to the viscosity measurement unit, a capillary inner diameter is set as d. By respectively using three or more values γof the shear rate, k being a natural number, the control device is configured to calculate injection velocities Vbased on Formula (1) and automatically sets a value of the injection velocity Vwithin a predetermined range, among the calculated injection velocities, as an injection velocity at a time of viscosity measurement.
