Our state-of-the-art Hydraulic Multi-Piston Moulding Machine is a versatile marvel, designed for use across various foundry workshops. Perfect for green sand up and down box moulding, it operates seamlessly as a stand-alone unit or can be integrated into a sophisticated mechanized assembly line. With its air cushion type full buffer pneumatic micro-vibration mechanism, there's no special foundation requirement. The innovative design includes a connecting rod synchronous shaft structure for the starting mold, complemented by pneumatic oil speed control, ensuring impeccable synchronization and freely adjustable speed.
Exquisite Features of the Hydraulic Multi-Piston Moulding Machine:
1. Utilizing advanced pneumatic multi-contact compaction, this machine eliminates oil leakage issues. Its ratio pressure is perfectly balanced, with no special sand model requirements. Featuring a substantial number of contacts (24-72), it is exceptionally suitable for intricate modeling tasks.
2. During compaction, the machine's frame remains stress-free, with the table securely hooked by four tie rods extending from the multi-contact body. The compaction process, driven by the downward extension of the multi-contact, relies on internal force, providing robust internal compaction strength as a unified system including the contact, hook, sand box, model plate, and table.
3. Experience superior pressing shock compaction where contact engages sand compaction. Simultaneously, the table participates in the shock process, independent of the rack, resulting in exceptional shock compaction effects. With high, uniform sand hardness reaching an average B hardness meter value of 85~90, the sand consumption is remarkably efficient, with sand eating volumes as minimal as 20~30mm. The sand eating ratio achieves an impressive H:B=2~3, maintaining the vertical cavity surface hardness above 80.
Key Components of the Hydraulic Multi-Piston Moulding Machine include the machine body, table, hydraulic piston contact box, mould starting mechanism, pneumatic contact box, and pneumatic piping system, each playing a critical role in ensuring top-notch performance.
1. The machine body is engineered as a robust hollow frame workpiece. Its upper section supports the swivel arm press head, which, during compaction, hooks securely onto the machine body to absorb press force. Bolted firmly to the shock mechanism, the swivel arm press head boasts a screw elevator, allowing precise press head-to-sand box distance adjustments, tailored to the sand box's height.
2. The work table, expertly crafted from ductile iron, is cast and shaped to match the precise dimensions of the sand box, ensuring durability and optimal performance.
3. Our Hydraulic Piston Contact Box is a sophisticated system comprising a multi-contact body, pneumatic multi-contact, and four pull hooks. The pneumatic multi-contact's structure focuses compaction inlet air on the multi-contact body, channeling it into an internal air cavity and the fixed piston's lower air cavity. This innovative design, influenced by air pressure on d1 and d2 minus the d3 area, delivers substantial pressure force, ensuring every sand type is perfectly compacted.
4. The mould starting structure is a well-coordinated system of two mould starting cylinders, a connecting rod, balance shaft, mould starting table, and mould starting rod. Upon activation, the cylinders drive the connecting rod and balance shaft, lifting the sand box and starting the mould simultaneously with the precision of four top rods.
5. Our Pneumatic Piping System is meticulously engineered to ensure operational excellence. Compressed air is filtered to remove water and impurities, then enhanced with lubricant from an oil mist injector, supplying every pneumatic component. Machine operations are effortlessly managed via a hand-pull valve console, ensuring smooth, reliable performance.
