REDUCED PRESSURE CASTING DEVICE

PROBLEM TO BE SOLVED: To provide a reduced pressure casting device that has a simple configuration for protecting a sealed part of a closed member from damage by preventing a molten metal from dripping out of a ladle and making contact with the sealed part.SOLUTION: The reduced pressure casting device 30 includes: a cylindrical injection sleeve 2 communicating with a cavity 4 formed in a mold 1; a flange part 8 formed on an outer periphery of the injection sleeve 2 and facing outward in a radial direction; a short columnar injection chip 3 inserted in the injection sleeve 2 slidably in a direction in which the chip comes close to and separates from the cavity 4; a closure member 10 disposed to be formable of a decompression chamber 11 enclosing a gate 6 and an opened side end 2a of the injection sleeve 2 by moving in a movement direction during injection operation of the injection chip 3; a sealing member 14 disposed between the closure member 10 and the flange part 8; and an eaves member 31 disposed at an upper end of the closure member 10 at the mold 1 side and extending to a mold 1 side than an abutment surface with the flange part 8.
