Our state-of-the-art Hydraulic Multi-Piston Moulding Machine is a versatile marvel, perfect for diverse foundry workshops seeking excellence in green sand up and down box moulding. Designed with seamless adaptability in mind, it can function as a stand-alone unit or integrate effortlessly into a mechanized assembly line. The machine features an innovative air cushion full buffer pneumatic micro-vibration mechanism, eliminating the need for special foundation requirements. With a sophisticated connecting rod synchronous shaft structure, it ensures impeccable synchronization of mould starting, while the pneumatic oil speed control offers the luxury of customizable speed management.
Characteristics of Hydraulic Multi-Piston Moulding Machine:
1. This advanced system embraces pneumatic multi-contact compaction, completely eliminating oil leakage concerns. With optimal pressure ratios and no special demands on model sand, it boasts an impressive number of contacts (24-72), making it ideal for creating complex moldings with ease and precision.
2. During the compaction process, the machine's frame remains unburdened, as the table is ingeniously supported by four tie rods descending from the multi-contact body. This downward extension facilitates internal force compaction, also known as internal compaction, whereby the contact, hook, sand box, model plate, and table form a harmonious system.
3. The machine excels in pressing shock compaction, where contacts press and compact the sand while the table vibrates independently from the frame, which remains free of vibration. This results in exceptional shock compaction efficiency, delivering high and uniform sand hardness (averaging 85~90 on the B hardness meter). The minimal sand eating volume of just 20~30mm, with a sand eating ratio achieving H:B=2~3, ensures even the cavity's vertical surface hardness exceeds 80.
The Hydraulic Multi-Piston Moulding Machine is an engineering masterpiece, composed of a sturdy machine body, versatile table, dynamic hydraulic piston contact box, sophisticated mould starting mechanism, pneumatic contact box, and a meticulously designed pneumatic piping system.
1. Crafted from robust materials, the machine body is a solid hollow framework supporting the swivel arm press head. During compaction, the swivel arm expertly hooks the machine body, distributing press force to the body itself. The press head, affixed to the swing arm, features a screw elevator to precisely adjust its distance from the sand box, accommodating varying sand box heights.
2. Engineered from ductile iron, the working table is both cast and shaped to accommodate varying sand box sizes, ensuring versatility and robust performance.
3. The hydraulic piston contact box is an intricate assembly of a multi-contact body, pneumatic multi-contacts, and four pull hooks. The pneumatic multi-contacts function on a unique principle: compaction inlet air concentrates within the multi-contact body's internal air cavity, simultaneously entering the fixed piston's lower air cavity through specialized channels. Under air pressure, the contacts attached to the cylinder barrel descend, applying formidable pressure to the sand type. This pressure equates to the sum of d1 and d2, minus the area of d3, multiplied by air pressure, yielding substantial force.
4. At the heart of the mould starting structure lies a sophisticated network of two mould starting cylinders, connecting rods, balance shaft, mould starting table, and rods. Once activated, the mould starting cylinder synchronizes the motion of connecting rods, balance shaft, and table to simultaneously elevate the sand box and initiate the moulding process with precision.
5. Our cutting-edge pneumatic piping system optimizes performance by channeling compressed air through an air filter, effectively removing moisture and impurities. Subsequently, an oil mist injects lubricant to supply each pneumatic component and institution. Operator actions are seamlessly controlled via a hand-pull valve console.
6. The system's air supply and lubrication are meticulously managed, utilizing air as the primary energy source and oil for lubrication. An intuitive pressure reducing valve and oil regulating valve allow for precise adjustment of inlet pressure and oil volume. The air source, through the oil fogger by siphon principle, is drawn into the pipeline, transforming into a fine mist that lubricates the entire system, ensuring optimal performance.
