Hydraulic multi-piston moulding machine can be used in various foundry workshops for green sand up and down box moulding, which can be used as a single machine or formed into a mechanized assembly line.The machine adopts air cushion type full buffer pneumatic micro-vibration mechanism, so there is no special requirement for the foundation, the starting mold adopts connecting rod Synchronous shaft structure, pneumatic oil speed control, good synchronization of mold starting, speed control freely.

characteristics of Hydraulic multi-piston moulding machine:
1.Adopting pneumatic multi-contact compaction, there is no trouble of oil leakage; the ratio pressure is moderate, there is no special requirement for model sand, the number of contacts is large (24-72), which is suitable for complex modeling.
2.When this machine is compacting, the frame is not under force, but the table is hooked by four tie rods hanging down from the side of the multi-contact body, and the compaction is carried out with the downward extension of the multi-contact, if the contact, hook, sand box, model plate and table are regarded as a system, this compaction strength is internal force or called internal compaction.
3.Pressing shock compaction, the contact on the one hand, sand compaction, at the same time with the table together with the shock (and the rack from the rack, the rack is not subject to vibration). Therefore, the shock compaction effect is good, the sand hardness is high and uniform (the average hardness reaches 85~90, the value of B hardness meter), the sand eating volume can be as small as 20~30mm, the sand eating ratio reaches H:B=2~3, and the hardness of the vertical surface of the cavity can still reach above 80.
