MAGNETIZATION DEVICE FOR MANUFACTURE OF SPLIT MAGNETIC MOULD Russian patent published in 1998 - IPC

FIELD: foundry. SUBSTANCE: working space of split magnetic mould is located between pole plates and split surface. Source of magnetic field in the form of electric coil is connected to source of electric energy. At least one permanent or replaceable pole piece is attached to pole plates close to split surface. Pole piece has shape of right-angled triangle in section. One leg of pole piece is positioned on pole plate and the other leg is located on split surface. Angle in section of pole piece facing inside of working space amounts to 10-45 deg to split surface. Pole piece is fabricated from material with enhanced magnetic permeability. Vertex of pole piece facing inside working space gives possibility of positioning of surface of space of mould near this vertex. EFFECT: reduced labor input into manufacture of split magnetic moulds. 3 cl, 2 dwg
