Abstract: An injection molding machine includes a feedback control system for controlling both the speed and position of a control object, such as a movable platen or an injection screw. The feedback control system includes a driving mechanism connected to the control object and a monitor monitoring the position of the control object. The monitor transmits signals representative of the sensed position of the control object. A speed control system controls the driving mechanism until the control object reaches a threshold position. Thereafter, a position control system controls the driving mechanism. A switch is provided to change the feedback control system from the speed control system to the position control system.

Abstract: Holding pressure-intended changeover speed Vh (provided, Vh.noteq.0) lesser than final set speed Ve in preselected speed control pattern Xv is selected while from deceleration rate Rh according to which screw 2 is decelerated at the time of,terminating final set speed Ve, holding pressure-intended changeover speed Vh and holding pressure-intended changeover position Sh, final deceleration start position Se in speed control pattern Xv, a segment of which extends, running through a point where holding pressure-intended changeover speed Vh and holding pressure-intended changeover position Sh is chosen; screw 2 is decelerated, following deceleration rate Rh when screw 2 arrives at final deceleration start position Se while injection control is in progress and when holding pressure-intended changeover position Sh or holding pressure-intended changeover speed Vh is reached, a shift is made to holding pressure control, whereby with even an electric motor-driven injection molding machine using a servo motor, a smooth shift from the injection process to the holding pressure process may be allowed; whereby it may become unnecessary to effect fine adjustment of a holding pressure-intended changeover position; and the quality of molded products and the productivity of injection molding machines may be improved.
