molding machine,shell mould machine

This machine is suitable for production of cope and drag moulds with green sand. It is characterized with multi-ram, so it especially suitable for castings shaped with complicated cavity. It not only can be used independently, but also can form a mechanical or semi-automatic moulding line. It is an economic option for medium moulding plant. 1.Adopts pneumatic multi-ram, no oil leak, suitable for castings shaped with complicated cavity; 2.The frame doesn’t bear strength when jolting and squeezing, it is inner jolting and squeezing; 3.The worktable jolts while the multi-ram compacts the sand moulds, so the effect of compaction and uniform will be better, average hardness of moulds surface can be up to 90. Mould thickness can be up to 20 30mm Max flask inside size:800×630×300mm Max flask outside size:1120×850×300mm Worktable size:950×730mm Working pneumatic pressure:≥0.55MPa Quantity of ram:48 Multi-ram squeezing stroke:200mm Squeezing pressure:3.8kgf/cm2 Jolting load:600kg Stripping stroke:300mm Output:35 40 half moulds per hour Air consumption:2.5 m3 per half mould Machine overall size:2165L×1630W×2300H mm Weight:5000kg
