APPARATUS AND METHOD FOR LUBRICATING A DIE CAVITY

摘要

An apparatus and method for applying a lubricant to an interior surface of a powder press die cavity (103) is provided. The apparatus includes at least one lubricant reservoir (121) operatively connected to a meter. There is a pump (102) for delivering and removing lubricant from the interior of the die cavity and a sequencing device (130) for sequencing the delivery and removal of the lubricant from the powder press die operatively connected thereto. At least one bore (111) goes through a wall of the press die and extends from the exterior of the die to the die cavity. The lubricant flows through this bore which openly communicates with the pump.
