Abstract
The accumulator of an extrusion blow molding machine is constructed so that the programming cylinder and die adjustment rod have axially aligned bores to receive a die pin retaining rod. The retaining rod holds the die pin in place by means of a lower split ring that nests inside the die pin and a lock nut combined with an upper split ring associated with the programming cylinder. When the lock nut is loosened and the upper split ring is removed, the retaining rod is moved down (while the die pin is held in place) and the lower split ring is removed. The die pin is then free to slide off the retaining rod and be removed from the accumulator head.
