ABSTRACT:
In a die, punch and core rod assembly for a powder compacting press wherein the core rod or rods remain stationary while the punch or punches are reciprocable relative to the die, the invention provides individual longitudinal position adjustment for the core rods by fitting the end of the core rods in a threaded member such as a set screw threading in a threaded bore in a core rod support member. The core rod support member is in the form of a pair of plates one defining a core rod support plate and the other a retainer plate, sandwiching a plastic locking plate. The core rods are immobilized in their adjusted position by the plastic locking plate, sandwiched between the core rod support plate and the retainer plate, being provided with a threaded bore aligned with the threaded bore in the support plate and having a slight screwthread mismatch with the threaded bore in the support plate.
