FIELD: foundry.
SUBSTANCE: casting method includes pouring melt out of a furnace into a mold located above the furnace by means of creating pressure on the surface of melted metal in the furnace. Free pouring is performed with open posts formed in the casting mold; at that the upper portion of the casting mold is pressure tight at least at the posts level. The mechanism is equipped with a mechanical arm for relocation of cover during casting under low pressure or relocation of pressure tight devices for the upper part of the casting mold.
EFFECT: simplification of the process and unification of equipment at casting.
