multi-contact green sand molding machine:
The machine is applicable to all various of foundry of clay sand molding
The machine not only can be used stand-alone, but also can be consisted mechanized assembly line. It also can be consisted semi-automatic production
1. Using the multi-contact pneumatic compaction, so no oil leakage problems; Moderate pressure, no special requirement for moulding sand, the number of the contact is 48 pieces, it is suitable for complex molding.
2. When the machine is compacting, the frame without stress, but the four tie bars hook the working table and compact. If the multi-contact finger、hook、 sand box、templet、working table as a system, the compact power is internal compaction.
3. The contact compact the sand over shock together with the working table( break away from frame, so the frame cannot be vibrated). so the hardness and uniform of the sand mould( the average hardness is 85-90), the mold thickness can be 20-30mm. the ration of mold thickness can be H:B=2-3. And the hardness of cavity vertical plane can be above 80.
The shock part of the machine is buffer spring, so it is no special requirements for the foundation
The drawing structure, it consists of drawing cylinder connected with synchronizing shaft, the drawing cylinder adopts air pressure control, so it can guarantee the drawing smoothly beginning
