MOULD WITH VERTICAL PLANE OR PARTING PLANES AND FOUNDRY BAY FOR CASTING AND COOLING IN ROW MOULDING PLANT Russian patent published in 1998 - IPC

FIELD: foundry. SUBSTANCE: mould and foundry bay are designed for manufacture of castings with subsequent feed after casting. In mould 32 with vertical parting plane each cavity 35 is connected by wide conduit to feeding vessel 36. When mould is filled gas pressure is applied to surface of metal in vessel 36 for subsequent feed through conduit 41. This gas pressure should not exceed metal static pressure on surface of metal in mould till metal in feeder 40 hardens or till this feeder is capped in any other manner. In point where conduit 41 opens to vessels 36 for subsequent feed it is closed with part 42 that is impenetrable for cast metal but penetrable for compressed gas. Pressure of gas can be increased when metal in feeder 41 hardness or feeder is capped in any other way. Runner 43 connected to source of compressed gas is located at bay for casting B and cooling C along direction of row of moulds. Runner is connected with conduits 41 of moulds. EFFECT: reduced consumption of metal for feed of castings. 7 cl, 2 dwg
