Abstract
A control device of an injection molding machine including an injection member that presses a molding material and an injection drive source that moves the injection member, includes: an injection control unit that controls, in a holding pressure process of controlling a pressure acting on the molding material from the injection member, the injection drive source based on a set value of the pressure and on an actual value of the pressure, in which the injection control unit uses a value subtracted over time from the set value of the pressure so that the actual value of the pressure gradually decreases with respect to the set value of the pressure, or uses a value added over time to the actual value of the pressure so that the actual value of the pressure gradually decreases with respect to the set value of the pressure.
