Abstract: The retraction of the screw is controlled on the basis of the pressure deviation between the set resin pressure and the detected resin pressure. Furthermore, the screw is caused to rotate at a set speed. Moreover, when the deviation between the metering completion position and the current screw retraction position drops to a value that is equal to or less than a set value, control of the retraction of the screw based on the pressure deviation is stopped, and the control is switched to positioning control based on the positional deviation. Furthermore, a screw rotational speed command in which the pressure deviation component between the set resin pressure and the current resin pressure is corrected from the screw rotational speed component that is decelerated in proportion to the positional deviation is determined and output.

Abstract: A injection molding machine includes a power device including a movable plate, a primary motorized cylinder having a primary threaded rod screwed through the movable plate, a secondary motorized cylinder having a secondary threaded rod screwed through the movable plate, a first starter mounted on the primary motorized cylinder and connected with a controller, and a second starter mounted on the secondary motorized cylinder and connected with the controller. The second starter contains a bias factor command and a preset output command. Thus, the normal torque output of the secondary motorized cylinder is close to that of the primary motorized cylinder by control of the bias factor command, and the preset output command limits and prevents the normal torque output of the secondary motorized cylinder from being greater than that of the primary motorized cylinder.

Abstract: An injection molding machine that performs a safe ejecting action of a molded article until a setting state of an ejector rod and a set forward end position for an ejection stroke of a molded article ejector are suitable for a mold in use. A resistor R1 is set to ON when a mold is changed and a resistor R2 is set to ON when a set value of the forward end position of the ejection stroke is changed. When resistor R1 or resistor R2 is ON, ejection is performed with a reduced ejecting force and at a reduced ejecting velocity. When a detected position of the ejector rod reaches the set forward end position, resistors R1 and R2 are turned OFF and thereafter the ejection is performed with a normal ejecting force and a normal ejecting velocity, to thereby prevent damage to the mold or to the molded article ejector.
