MOULD FOR FORMING BLANKS OF TURBINE BLADES BY HOT SLIP CASTING UNDER PRESSURE Russian patent published in 2024 - IPC B28B1/24 B28B7/04 

FIELD: foundry.

SUBSTANCE: invention relates to foundry, namely, to process equipment used in forming turbine blades by hot slip casting under pressure. Mould for turbine blade blanks comprises casing, top and bottom covers, split mould with shaping surfaces to shape blade blank, mould retainer, mark and gate ring. At the same time, the upper and lower covers form connection surfaces of the blade workpiece. Sign is installed in the upper cover. Gating ring is installed at the bottom of the mould. Mould is made of two parts with the possibility of their movement in a circle, the axis of which coincides with the common axis of the blade surface. Positioning of the mould relative to the mould body is carried out by annular projections made with possibility of entering the annular grooves in the body. Axes of the projections and slots coincide with the common axis of the blade surface.

EFFECT: higher quality of articles with preset geometry.
