PURPOSE: A tiltable gravity die casting machine is provided to improve quality of the cast article by cutting off inflow of oxide film formed on the surface of melt into cavity through blowing means, thereby preventing defects of cast article. CONSTITUTION: In a tiltable gravity die casting machine comprising a stand(20), die frame(24) rotationally installed by being hinge connected to one end of the stand, a hydraulic cylinder(22) installed between the stand and die frame to rotate the die frame, fixed die(26) and operating die(28) installed inside the die frame, a hydraulic cylinder(30) installed to operate the operating die, cavity and injection port formed on the contact surface of the fixed die and operating die, and a melt storage member(32) installed at the tip of the injection port to store melt temporarily, the tiltable gravity die casting machine is characterized in that a blowing means(34) is installed at the upper part of the outlet tip of the melt storage member, and the blowing means comprises a compression tank(36) into which air is compressed, a valve(38) for regulating supply of air pressure, a controller(40) for adjusting opening and closing of the valve, a blowing pipe installed on the upper part of the melt storage member by being parallel to the melt storage member, and injection nozzles installed on the upper part of each outlet side of the melt storage member, wherein injecting direction of the injection nozzles is opposite to a melt injecting direction of the melt storage member.
