METHOD OF CAST WHEEL MANUFACTURING AND CASTING MOULD Russian patent published in 2015 - IPC B22D15/00 B22C9/10 

FIELD: metallurgy.

SUBSTANCE: in the casting mould (1), having bottom (5) and top half-moulds (4), moving towards each other for the half-mould (1), closure, the rod (3) is installed, it stays in the cast wheel (2′). The rod is made with rim (17) along perimeter. The rod (3) is positioned in the given position in the casting mould (1) by means of at least one positioning element (7). End segment of the positioning element (7) is locked by power or friction closure in the located along perimeter rim (17) of the rod (3). The free end segment of the positioning element (7) at distance from the located along perimeter rim (17) of the rod (3) is installed on the located in work position mainly in horizontal plane support surface (8) of bottom half-mould (5) with rod positioning under gravity force.

EFFECT: accurate rod positioning in the casting mould at maximum possible freedom of the rod manufacturing.
