Patent ID: 7041242

Claim:
A mold-clamping control method for an injection molding machine, comprising: detecting a value of a monitor item in a monitor region predetermined in relation to a mold closing operation during the course of a mold clamping step; performing emergency processing when the detected value exceeds a threshold value; presetting 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 on the basis of the anomalous-state mold opening velocity is ended; and performing the mold opening control on the basis of the anomalous-state mold opening velocity 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.
