The machine is generally used for foundry casting workshop, mechanical production lines or semi-mechanical production lines and suitable for batch production of small size molding piece single faced plate and single box mode,up box and down box be made.The machine adopt spring microseism pressing structure, pressing cylinder wide, pressing strength strong is good for molding quality, pneumatic pipe simple, easy control and convenience.
A. Pneumatic multi-contact compaction is adopted to optimize the design of the machine, without oil leakage; moderate specific pressure, no special requirements for sand, more compaction contacts (48pcs), suitable for complex moulding.
B. High pressure compaction, the multi-contacts compacts sand molding, and vibrate with working table(separated from machine frame, and frame without vibration). Therefore, good vibration effect, high hardness and uniform sand moulding(average hardness 85~90 , B type hardness tester),the sand consumption can be as small as 20~30 mm, the compaction ratio is up to 4.2, and the vertical surface hardness of the mold cavity can still reach above HB80.
C. The machine adopts the spring micro-vibration compaction mechanism, large compaction cylinder diameter, high pressure strength,compacted and even sand moldings, it can guarantee quality of casting.The mold stripping structure adopts way of air oil pressure, the mold stripping adopts connecting rod, the synchronous shaft structure, the pressure oil speed regulation, good mold stripping synchronization, realizes the stable drawing by the two lifting cylinders, the connecting rod, and the synchronous shaft. Simple pneumatic pipeline, easy and flexible operation, convenient operation, The machine adopts the spring fully cushioned pneumatic micro-vibration mechanism, no special foundation requirement.
D. The machine increases the stroke of the compaction cylinder, adopts multiple mechanisms to increase the pressure strength, and at the same time, it can pressurize and vibrate according to actual need, so that the elevation and plane hardness of the sand type (including type of complex sand moulding ) are compact and even. Convenient operation and high productivity.
E. Sand mold casting pouring thin-wall castings, precise size, smooth surface.h productivity.
