Abstract
There are provided a first process Tin which a mold clamping motoris driven-controlled so as to move a cross headof a toggle link mechanismto a preliminary position Xr set in advance so as to become a position on the mold open side rather than a mold closure position Xs; a second process Tin which after the first process Tis finished, a mold thickness adjusting motoris driven-controlled so as to move a pressure receiving platenforward to a mold closed position Xc where a mold C is closed; a third process Tin which after the second process Tis finished, the mold clamping motoris driven-controlled so as to move the cross headforward, while the mold C is pressurized by torque limitation of the mold clamping motor, and the mold thickness adjusting motoris driven-controlled so as to move the pressure receiving platen, while the cross headis moved to the mold closure position Xs; and a fourth process Tin which, after the third process Tis finished, a clamping margin Lp of the mold C corresponding to a predetermined mold clamping force is set.
