ABSTRACT:
A sealing arrangement for the molten metal portion of a lost core molding assembly includes a cooling chamber placed adjacent an opening of a heated nozzle chamber. The cooling chamber includes a generally cylindrical passageway that is aligned with the opening in the heated chamber distant from a tip of the nozzle. The generally cylindrical passage includes a reservoir, of a preselected axial length, for collecting a portion of the molten material that is allowed to enter into the passage. The collected material is cooled and solidified within the reservoir in order to form a generally annular bushing around a moving member that moves through the passage and the opening in the heated chamber while still permitting the moving member to move in a controlled manner. The annular bushing that is formed is self-repairing as additional molten material contacts the bushing and solidifies as part of the bushing.
