Our state-of-the-art Hydraulic Multi-Piston Moulding Machine is the epitome of innovation and efficiency, perfectly crafted for diverse foundry workshops. This robust machine is adept at handling green sand up and down box moulding, offering unmatched versatility as either a standalone apparatus or as an integral part of a mechanized assembly line. The machine boasts an air cushion type full buffer pneumatic micro-vibration mechanism, eliminating the need for special foundational requirements. With its connecting rod synchronous shaft structure and advanced pneumatic oil speed control, it ensures unparalleled synchronization and flexibility in mold starting, making speed control a breeze.
Key Characteristics of the Hydraulic Multi-Piston Moulding Machine:
1. Embracing cutting-edge pneumatic multi-contact compaction, this machine sidesteps the hassles of oil leakage. With a balanced pressure ratio, there is no necessity for specific model sand, as the machine accommodates an impressive number of contacts ranging from 24 to 72, catering effortlessly to complex modeling needs.
2. During the compaction process, the frame experiences no force. Instead, the table is ingeniously secured by four tie rods descending from the multi-contact body’s sides. Compaction occurs as these multi-contacts extend downward, forming an integrated system with the contact, hook, sand box, model plate, and table. This unique approach harnesses internal force, aptly termed internal compaction, ensuring robustness and precision.
3. The machine’s pressing shock compaction is a marvel of engineering, combining sand compaction with synchronized table vibration. This innovative design delivers exceptional shock compaction results, achieving sand hardness levels that are both high and uniform, averaging between 85 and 90 on the B hardness scale. The machine’s efficiency is further highlighted by a minimal sand consumption volume, ranging from 20 to 30mm, while maintaining an impressive sand eating ratio of H:B=2~3. The vertical cavity surfaces also boast hardness levels above 80, guaranteeing superior performance.
The Hydraulic Multi-Piston Moulding Machine is a sophisticated assembly comprising the machine body, table, hydraulic piston contact box, mould starting mechanism, pneumatic contact box, and an intricate pneumatic piping system, all meticulously engineered for optimal functionality.
1. The machine body is a durable hollow framework, designed to support the swivel arm press head. During compaction, this swivel arm ingeniously hooks to the machine body, transferring the press force directly onto it. The solid connection of the machine body and shock mechanism, secured with bolts, ensures stability, while the swivel arm press head, equipped with a screw elevator, deftly adjusts the press head’s proximity to the sand box, accommodating varying sand box heights with ease.
2. The robust working table, crafted from ductile iron, is precision-cast and shaped to align with the sand box’s dimensions, offering reliability and strength.
3. The hydraulic piston contact box is an engineering marvel, consisting of a multi-contact body, pneumatic multi-contact, and four strategically placed pull hooks. At its core lies the pneumatic multi-contact structure principle: the compaction inlet air is expertly channelled to the multi-contact body’s internal air cavity, simultaneously entering the fixed piston’s lower air cavity through a specialized channel. The force generated from the sum of d1 and d2, minus the area of d3, multiplied by air pressure, results in a powerful pressure force, ensuring precise sand type application.
4. The mould starting structure is a seamless integration of two mould starting cylinders, connecting rods, balance shaft, mould starting table, and mould starting rods. As the mould starting cylinder activates, it orchestrates the coordinated motion of these components, lifting the sand box and initiating the mould with precision.
5. The pneumatic piping system is expertly designed to filter and refine compressed air, removing impurities and moisture before channeling it through an oil mist for lubrication. This ensures the robust operation of all pneumatic components and mechanisms, with machine actions precisely controlled via a user-friendly hand-pull valve console.
