A frame assembly for a lower blanking tool of a carton die cutting machine. The frame assembly includes an outer frame comprised of a pair of opposite longitudinally extending side rails and a pair of opposite cross rails extending crosswise between the side rails. Each of the cross rails has a T-shaped slot formed therein opening to its inner surface, and each of the side rails have a T-shaped slot formed therein opening to its upper surface. Each slot extends downwardly at an acute angle with respect to a horizontal plane. A plurality of corner pieces rigidly interconnect the rails together with fasteners extending into the T-shaped slots of adjacent side and cross rails so that when tightened, the corner pieces function like clamps to rigidly interconnect the rails together.
