APPARATUS FOR COMPACTING MOLD SAND Russian patent published in 2000 - IPC

Abstract RU 2159165 C2

FIELD: foundry, possibly manufacture of casting molds. SUBSTANCE: apparatus includes elastic members for joining compacting plate with pulse head in such a way that plate may be moved towards flask by action of compressed air and to provide dynamic ( shock) pressure acting upon mold sand. Compacting plate is latticed one and it serves as dissector of compressed air flow. Mold sand is compacted simultaneously by compressed gas impulses and mechanical pressure of compacting plate. EFFECT: enhanced uniformness of distributing density of mold sand by volume. 3 cl, 2 dwg
