DIE CAST FORMATION OF BERYLLIUM COPPER PLUNGER TIPS

摘要

A method for producing a plunger tip suitable for use in metal die casting operations, commences with a metal mold comprising at least two mold portions (16a, 18b), which mold portions (16a, 18b) mate for forming a casting mold. A core (40) is extended into spaced-apart relationship with at least one of the mold portions (16a, 18b) and the mold portions (16a, 18b) are moved into mating relationship with the core (40) disposed therewithin. The mated mold portions (16a, 18b) are rotated from a vertical position into a horizontal position. A trough (46) is disposed in fluid communication with the mated mold portions (16a, 18b). Molten metal is poured into the trough (46). The mated mold portions (16a, 18b) and trough (46) are rotated into a position between horizontal and vertical for any molten metal in the trough (46) to flow into the mated mold portions (16a, 18b) and then back into a vertical position. Finally, the plunger tip is removed from the parted mold portions (16a, 18b).
