Abstract: A display device with a touch panel and a controller having a computer function to display various kinds of screens on a display surface of the display. The controller includes a multiple screen display processing function part wherein at least two independent screen display parts are displayed side by side, a screen switch processing function part to enable switching of a touched screen to the other screen by a touch/slide operation on the screen, and a switch key display processing function part by which a key display part is arranged on the display surface in an area other than the screen display parts. A plurality of switch keys are arranged and displayed in the key display part according to a key pattern corresponding to the order of the screens switched by a touch/slide operation so as to enable selection of the screens to display by a touch operation.

Abstract: There are provided a first process T1 in which a mold clamping motor 4 is driven-controlled so as to move a cross head 5h of a toggle link mechanism 5 to a preliminary position Xr set in advance so as to become a position on the mold open side rather than a mold closure position Xs; a second process T2 in which after the first process T1 is finished, a mold thickness adjusting motor 2 is driven-controlled so as to move a pressure receiving platen 3 forward to a mold closed position Xc where a mold C is closed; a third process T3 in which after the second process T2 is finished, the mold clamping motor 4 is driven-controlled so as to move the cross head 5h forward, while the mold C is pressurized by torque limitation of the mold clamping motor 4, and the mold thickness adjusting motor 2 is driven-controlled so as to move the pressure receiving platen 3, while the cross head 5h is moved to the mold closure position Xs; and a fourth process T4 in which, after the third process T3 is finished, a clamping margin L

Abstract: Test molding is performed by sequentially clamping a mold 2 with a mold clamping force (100%, 80%, 70%, . . . ) obtained by sequentially lowering a mold clamping force by a predetermined amount from the maximum mold clamping force (100%); with mold position sensors 4 provided on outer surfaces 3cf and 3mf of a fixed platen 3c supporting a fixed mold 2c of the mold 2 and a movable platen 3m supporting a movable mold 2m of the mold 2, a relative position (mold position Xc) of the movable platen 3m with respect to the fixed platen 3c in an injection process is detected; and, when at least a variation that meets predetermined conditions is produced on the mold position Xc, a mold clamping force obtained by increasing a mold clamping force at a time of occurrence of the variation by a predetermined amount is set as a proper mold clamping force Fs.

Abstract: In a drift detection method for detecting drift in a pressure detection value output from a pressure detector, pressure is detected by the pressure detector at a preset detection point in a pressure-uncontrolled region in an arbitrary molding cycle. The detected pressure is set as a reference pressure. Pressure is detected by the pressure detector at the same detection point in the pressure-uncontrolled region in a subsequent molding cycle. A deviation of the detected pressure from the reference pressure is obtained. When the deviation is greater than a preset value, it is determined that a drift is present, and processing for coping with the drift is performed.

Abstract: In a correction method for correcting a pressure detection value output from a pressure detector used in a control apparatus which controls an injection molding machine, the screw of the injection molding machine is rotated by one turn in a period in which molding operation is not performed, and a middle value between the minimum value and the maximum value of a pressure detection value output from the pressure detector during the rotation is obtained. The screw is rotated further and is stopped when the pressure detection value becomes equal to the middle value. The pressure detection value output from the pressure detector after stoppage of the screw undergoes correction.
