ABSTRACT:
The value of a monitor item is detected in a monitor region predetermined in relation to a mold closing operation during the course of a mold clamping step. Emergency processing is performed when the detected value exceeds a threshold value. There are preset an anomalous-state mold opening velocity higher than a normal-state mold opening velocity on the basis of which mold opening control is performed in a normal state, and an anomalous-state-velocity end position at which mold opening control based on the anomalous-state mold opening velocity is ended. Mold opening control based on the anomalous-state mold opening velocity is performed in a portion of the monitor region ranging from a point corresponding to time when the detection value has exceeded the threshold value, to a point corresponding to the anomalous-state-velocity end position.
