ABSTRACT:
A rear platen is moved forward toward a fixed platen as much as the amount corresponding to a mold clamping force which is set in advance, in a state in which the toggle mechanism of a toggle type mold clamping system is contracted, to detect that a fixed mold half attached to the rear platen touches a movable mold half attached to the fixed platen. When mold touch is detected, the rear platen is moved backward as much as the amount of stretch of a tie bar which is generated from the mold touch.
