A mold-clamping control method for an injection molding machine includes the steps of detecting a value of a monitor item in a monitor region predetermined in relation to a mold closing operation in a mold clamping step; performing emergency processing when the detected value exceeds a threshold value; and performing an automatic setting operation. This automatic setting operation includes the steps of periodically detecting the value of the monitor item in the monitor region at predetermined sampling intervals to thereby obtain detection values in sampling order; repeating the step of periodical detection for each of a predetermined number of shots; obtaining threshold values and torque limit values for individual places of sampling order, on the basis of the detection values, by use of predetermined arithmetic expressions; and storing the obtained threshold values and torque limit values for control use.
