The Hydraulic Multi-Piston Moulding Machine is a versatile powerhouse, designed to elevate the efficiency of various foundry workshops. This engineering marvel excels in green sand up and down box moulding, functioning splendidly as both a standalone unit and a key component of a mechanized assembly line. Its ingenious air cushion full buffer pneumatic micro-vibration mechanism eliminates the need for special foundation requirements. With a connecting rod synchronous shaft structure and pneumatic oil speed control, it ensures seamless mold synchronization and effortless speed adjustments.
Remarkable Features of the Hydraulic Multi-Piston Moulding Machine:
1. Embrace the reliability of pneumatic multi-contact compaction, a technology that sidesteps the nuisance of oil leaks. The ratio pressure is perfectly balanced, requiring no special considerations for model sand. With an extensive range of 24 to 72 contact points, this machine is tailored to accommodate intricate modeling tasks with ease.
2. During the compaction phase, the frame remains unaffected by force, as the table is ingeniously suspended by four tie rods descending from the multi-contact body. Compaction occurs as the multi-contact extends downward, integrating the contact, hook, sandbox, model plate, and table into a cohesive system. This results in what is known as 'internal force' or 'internal compaction,' ensuring robust strength.
3. Indulge in the efficacy of pressing shock compaction, where contacts compress sand in tandem with the table, all while the rack remains vibration-free. This synchronization delivers outstanding shock compaction results, achieving uniform sand hardness with an average hardness of 85 to 90 on the B hardness meter. Remarkably, the sand consumption is minimized to 20-30mm, achieving an impressive sand consumption ratio of H:B=2-3, while maintaining vertical cavity surface hardness above 80.
The Hydraulic Multi-Piston Moulding Machine is a sophisticated assembly, featuring a robust machine body, a versatile table, a hydraulic piston contact box, an advanced mold starting mechanism, a pneumatic contact box, and an intricate pneumatic piping system.
1. At the heart of the machine is a solid hollow frame workpiece, supporting the swivel arm press head component. During compaction, the swivel arm hooks the machine body, transferring the press force seamlessly. The machine body is meticulously bolted to the shock mechanism, with the press head fixed to the swing arm. A screw elevator adjusts the distance from the press head to the sandbox, accommodating varying sand box heights with precision.
2. Crafted from ductile iron, the working table is a testament to durability. It is cast and shaped to match the size of the sandbox, ensuring a perfect fit for every task.
3. The hydraulic piston contact box is an intricate composition of a multi-contact body, pneumatic multi-contacts, and four pull hooks. The pneumatic multi-contact mechanism's principle focuses on channeling compaction inlet air to the internal air cavity of the multi-contact body, while simultaneously directing air pressure to the lower air cavity of the fixed piston. The result is a harmonious pressure application on the sand type, achieving formidable pressure through the calculative sum of d1 and d2, subtracted by the area of d3, multiplied by the air pressure.
4. The mold starting structure is a symphony of engineering, comprising two mold starting cylinders, a connecting rod, a balance shaft, a mold starting table, and a mold starting rod. Upon activation, the mold starting cylinder orchestrates the movement of the connecting rod, balance shaft, and mold starting table, elevating the four top rods to lift the sand box and initiate the mold with synchronized precision.
5. The pneumatic piping system is an intricate network, purifying input compressed air through an air filter, removing water and impurities. It then delivers essential lubricant through an oil mist injector, ensuring each pneumatic component and mechanism operates smoothly. Machine actions are effortlessly controlled via a hand-pull valve console, optimizing performance and reliability.
