Abstract
A vertical injection apparatus for a die casting machine is disclosed. The setting is made such that a timing for vacuum evacuation applied to a portion into which air enters is suitably earlier than that for vacuum evacuation applied to a die cavity. Thus, this allows a solidification layer tightly formed on the end surface of a plunger tip to prevent air from entering into the die cavity, making it possible to desirably carry out injection and to remarkably improve quality of casting products. By improving the structure for holding a vacuum evacuating tube, this apparatus can facilitate repairing word required when the evacuating tube is clogged with hot molten metal.
