Abstract

A pull or push rod or locking nut for a molding machine has an undercut, and the undercut has an undercut cross-section, a side wall, and an undercut ramp. The side wall transitions via a first transition curvature into an undercut base, and the undercut base transitions via a second transition curvature into the undercut ramp. The undercut base, viewed in the undercut cross-section, is at least partially curved, and the curvature of the undercut base differs from the first transition curvature and/or the second transition curvature.
