Abstract

PURPOSE: To fill molten metal without any defects such as gas holes, misruns, etc. by letting a pressing piston descend at a speed faster than that of a pressure receoving piston.
CONSTITUTION: Molten metal M is poured and reserved in the sleeve 4 between a pressing side plunger piston 8 and a pressure receiving side counter piston 6. Next, the plunger piston 8 is fitted into the opening 4a of the sleeve 4 and is lowered. At this time, a space S is given between the molten metal M and the plunger piston 8. next, both pistons 6, 8 are started and the descending speed is so increased that when the counter piston 6 descends down to the filling position 5 the plunger pistion 8 catches up with the head M1 of the molten metal M. Then, the air of the space S is expelled through the clearance between the piston 8 and sleeve 4 in the catch-up process, thus the molten metal M is pressure-filled from the filling position 5 without the entry of the air layer into the molten metal M.
