EJECTOR, SEMI-SOLIDIFIED METAL PRODUCING APPARATUS AND DIE CAST MACHINE

摘要

To provide an ejector by which uniform spraying of an object-of-ejection to a vessel can be made easy.SOLUTION: An ejector 45 is for spraying an object-of-ejection (gas or mold-release agent) to a hollow member 53. The hollow member 53 constitutes a side portion 41a, of a vessel 41 to cool a poured liquid metal material M into a semi-solidified form, surrounding a predetermined axis CL extending in a depth direction of the vessel 41 about the axis. The ejector 45 has a hold member 65 that holds the hollow member 53, and one or more nozzles (mold-release agent nozzle 67, internal gas nozzle 69 and a plurality of external gas nozzles 71) for ejecting an object-of-ejection toward the side portion 41a, and a rotator 75 that rotates the hold member 65 about the predetermined axis CL.SELECTED DRAWING: Figure 4
