Abstract
A method and system of controlling a screw engaging position adjuster provided in a complex mold clamping system. A theoretical deviation of a screw engaging position is theoretically calculated on the basis of a distance by which a movable die has been moved from an origin set for a mold thickness adjustment in clamping process. A measured deviation of the screw engaging position is measured from a distance between a mold clamping cylinder and a movable platen in clamping process. The screw engaging position adjuster is so controlled that a difference between the theoretical deviation and the measuring deviation is within an allowable deviation having previously been set.
