METHOD OF CLOSING MOLD INLET AFTER NONGRAVITY CASTING OF NONIRON ALLOY IN GREEN-SAND MOLDS OF ROW PLANT (VERSIONS) Russian patent published in 1999 - IPC

Abstract RU 2127172 C1

FIELD: foundry. SUBSTANCE: method involves attachment of cylindrical hollow member in mold so that its external part forms inlet system. During casting, nozzle of teeming device comes in contact with member external end face. Melt is poured into mold through nozzle channel of hollow member and mold gate. After completion of pouring, nozzle is pressed to member with force exceeding the force of contact in the course of pouring. Member is displaced inside mold to shut off mold inlet. Three other versions of the method are described in the invention description. EFFECT: precluded breakage of mold round inlet opening and getting of molding sand to casting. 13 cl, 23 dwg
