Abstract: A method for controlling a motor-driven injection molding machine which includes a plurality of drive motors. In the method, load current flowing through at least one drive motor serving as a drive source is detected in order to estimate heat generation value of the drive motor. When the estimated heat generation value reaches a preset stopping point, the drive motor is stopped. When the estimated heat generation value reaches a preset alarming point, which is lower than the stopping point, an alarm is issued.

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.

Abstract: A method for controlling a motor-driven injection molding machine in which heat generation of a drive section including a drive motor is monitored, and when the drive section enters an overload state, the drive motor is stopped. In the method, during molding, heat generation value (overload factor) of the drive motor is estimated from load current flowing through the drive motor. When the estimated heat generation value (overload factor) reaches a preset stopping point or when a thermostat attached to the drive section outputs an overload detection signal indicating an overload state, the drive motor is stopped.

Abstract: A protection apparatus for an injection molding machine includes an overrun detection mechanism and a control section. The overrun detection mechanism includes an element to be detected which is attached to one of a movable member of a movable mechanism and a stationary member facing the movable member, and a detection unit attached to the other of the movable member and the stationary member. The detection unit detects the element when the movable member has moved to an overrun position. The control section forcedly stops operation of a drive unit which moves the movable member, when the detection unit detects the element. In a case in which the control system of the injection molding machine suffers erroneous operation or temperature drift and a movable member is on the verge of overrun during operation of the injection molding machine, when the movable member moves to the preset overrun position, the element is detected by the detection unit, so that the control section forcedly stops the operation of the drive unit which moves the movable member.
