Claim 4:
5. A method of adjusting a mold thickness of a mold clamping device in which opening and closing of a movable platen is performed by rotating a mold opening/closing screw shaft to move a mold opening/closing nut and moving a mold clamping shaft integrated with the mold opening/closing nut, and mold clamping of the movable platen is hydraulically performed by a mold clamping ram incorporated in a support platen pressing the mold clamping shaft,
the method of adjusting a mold thickness of a mold clamping device comprising:
a difference value calculation step of calculating a difference value of a first mold closing position of the movable platen for a first mold, and a second mold closing position of the movable platen for a second mold;
a movement position calculation step of calculating a movement position of the mold clamping ram on the basis of a current position of the mold clamping ram and the difference value; and
a mold clamping step of performing mold clamping of the movable platen by engaging a half nut coaxially attached to a distal end of the mold clamping ram with the mold clamping shaft after the mold clamping ram is moved to the movement position.
