1, put the sandbox that contains bleed room on oscillatory platform, tighten with card of mould special fixture. The end that bottom puts certain ply is arenaceous (general bed ply is in 50~100mm above) , vibration close fact. Sandbox is bosseyed mouth, set bleed room or bleed canal, remove condole or walk the sandbox of the orgnaization. 2, set EPS model brace up after fact, according to craft the requirement sets EPS model group on its, earth up arenaceous fixed. 3, fill arenaceous join dry arenaceous (a few kinds add arenaceous method) , pass vibration of oscillatory platform inflict at the same time (X, Y, Z3 direction [three-dimensional vibration] ) , time is 30~60 second commonly, make molding sand fills each position of the model, and make the accumulation density of molding sand increases. 4, sealed surface of box of calm molding sand uses plastic film sealed, with vavuum pump certain vacuum will be smoked inside sandbox, the poor will arenaceous bead that leans atmosphere force and power of casting mould internal pressure " felt " together, maintain casting mould pouring the process does not die medicinal powder, those who say for " negative pressure finalizes the design. Relatively commonly used. Personalized design creates oscillatory platform a few big characteristics: Bedspring of air of control of frequency conversion of tool clamping apparatus is decreased brace up high strenth bolt joins (nylon locknut) platform of vibration of frame of steel structure report is upgrading in innovation design.
