摘要:
There is disclosed a mold protection apparatus of an injection molding machine in which a cross head position and movable mold position are read from a correspondence table, a calculator calculates a thrust force limit value set with respect to a movable mold, and a cross head position controller controls a thrust force of the cross head in the corresponding position via a servomotor, so that the thrust force of the cross head is controlled to indicate a limit value or less in accordance with position of the movable mold.
