A die block assembly includes a sliding block (50) and a die plate (70). The sliding block has a base (53) from which a pair of slanted rails (58) extends. A protrusion (61) with a vertical outer wall (62) extends from an end of the base, between the rails. The die plate defines an opening (72) for movably receiving the block. A pair of slanted guiding grooves (74) is defined in the plate, for slidably receiving the rails of the sliding block. A recess (76) bounded by a vertical inner wall (78) is defined in the plate, for movably receiving the protrusion of the block. Upon assembly, in a first position, a clearance exists between the outer wall of the block and the inner wall of the recess. In a second position, the outer wall abuts the inner wall. Thus movement of the block is limited to a predetermined range.
