Abstract
A technique for managing a shear heating value of a molding material is provided. A control device of an injection molding machine individually controls outputs of a plurality of heating units for a plurality of zones, respectively, into which a cylinder is divided in a flow direction of a molding material. The control device acquires the output of the heating unit provided in a predetermined zone both in a steady state in which an operation of a screw provided inside the cylinder is stopped and at a time of molding at which the operation of the screw is performed, and calculates a difference in output of the heating unit provided in the predetermined zone between at a time of molding and in the steady state.
