PROBLEM TO BE SOLVED: To enable an improvement in casting product quality by cooling down to a sufficient micronized structure when supplying molten metal that is a casting material into a die cast machine.SOLUTION: A ladle 2 that pumps up molten metal S that is a casting material from a molten metal holding furnace 1 is oscillated when supplying the molten metal S into a predetermined die cast machine by casting out of the molten metal holding furnace 1 into an injection sleeve 5. For that purpose, the apparatus includes a ladle movement mechanism part 10 that moves the ladle 2 with the pumped-up molten metal S and a ladle oscillation mechanism part 20 that oscillates the ladle 2 filled with the molten metal S. The ladle oscillation mechanism part 20 includes a trestle 21 disposed in the vicinity of the molten metal holding furnace 1, an oscillation part 23 disposed on the trestle 21, and a ladle loading table 25 provided on the oscillation part 23. The oscillation part 23 includes an air vibrator based on a compression type spring dumper structure 24 driven by compressed air.SELECTED DRAWING: Figure 1 |
