Abstract: An injection molding machine includes a storage unit in which input information input via an operation unit and a molding condition under which molding is performed using a gain specified by the input information are stored in association with each other, and a control unit configured to generate a signal with a feedback-control, which uses a difference between a set value used to control an object to be controlled and an actual value measured from the object to be controlled and the gain specified by the input information associated with the molding condition, and to control a drive source using the signal to perform the molding, in a case where the molding indicated by the molding condition is performed.

Abstract: An injection molding machine includes an injection member that pushes a molding material and an injection drive source that moves the injection member. A control device of the injection molding machine includes an injection control unit that controls a stop process for stopping a movement of the injection member and a holding pressure process for controlling a pressure acting on the molding material from the injection member, a pressure monitoring unit that monitors an actual value of the pressure in the stop process, and a timing setting unit that sets a timing when the stop process is to be switched to the holding pressure process on the basis of the actual value of the pressure in the stop process and a value offset from a set value of the pressure at a time of start of the holding pressure process to a high pressure side by a predetermined amount.
