A B S T R A C T In an injection molding machine which performs movement control such that the rotation and axial movement of a screw (1) in a cylinder (10) are controlled in accordance with set injection molding conditions and executes an injection process for injecting a plasticized resin, for use as an injection object, into a mold (12), an injection molding condition settling method for the injection molding machine comprises: information detection process for detecting information on a time-based pressure acting on the resin in the injection process by means of injection pressure sensors (4, 13, 14), etc.; a first display control process for causing a pressure curve corresponding to the pressure information detected in the information detection process to be displayed in a waveform display region provided in a screen of a CRT display device of a CRT/MDI (119); a second display control process for causing information on set values of the injeciton molding conditions to be displayed in a condition settling region provided in the screen of the CRT display device the moment the pressure curve is displayed when the display of the injection molding conditions is selected; and a condition setting process for settling the injection molding conditions in response to a modification of the set values displayed on the screen of the CRT display device. According to this method. the set values of the injection molding conditions can be modified while observing the pressure curve displayed on the screen of the CRT display device simultaneously therewith.
