Abstract
A structure for measuring the load imposed on mold halves in a plastic injection molding machine when engaged to define a mold cavity, the machine being of a type wherein a movable die platen is driven along supporting tie rods to carry one mold half toward and away from a fixed die platen carrying the other mold half. The measuring is accomplished by a sensor engaging one end of one tie rod to sense any movement thereof under an imposed load condition.
