Abstract
With respect to a controller of an injection molding machine, the injection molding machine includes an injection member provided inside a cylinder to heat a molding material and an injection drive source to fill the molding material into a mold device by moving the injection member forward. The controller includes a limiting part that limits a movement of the injection member forward in a pressure-holding process of controlling an injection drive source so that an actual value of a filling pressure acting on the molding material from the injection member becomes a set value, and a determining part that determines an appropriateness of a setting to be used by the limiting part based on information of a sensor provided in the mold device.
