The Hydraulic Multi-Piston Moulding Machine from Qingdao Sanzhuji Technology Co., Ltd. is a versatile powerhouse, designed to elevate foundry workshops with its green sand up and down box moulding capabilities. Whether used as a standalone marvel or integrated into a mechanized assembly line, this machine is built for excellence. It features an air cushion type full buffer pneumatic micro-vibration mechanism, negating the need for special foundation requirements. The starting mold utilizes a sophisticated connecting rod synchronous shaft structure, paired with pneumatic oil speed control, ensuring impeccable synchronization and effortless speed modulation of mold starting.
Characteristics of the Cutting-Edge Hydraulic Multi-Piston Moulding Machine:
1. Utilizing innovative pneumatic multi-contact compaction, this machine eliminates the hassle of oil leakage. With a moderate ratio pressure, it requires no special model sand, featuring a large contact count ranging from 24 to 72, making it an ideal choice for complex modeling tasks.
2. During the compaction process, the machine's frame remains unburdened as the table is secured by four tie rods hanging from the multi-contact body. The compaction strength is characterized as internal force or internal compaction, which is achieved through the downward extension of the multi-contact. This system, comprising the contact, hook, sand box, model plate, and table, ensures robust and efficient compaction.
3. The machine excels in pressing shock compaction, where the contacts synchronize sand compaction with table movements, separate from the rack that remains vibration-free. This results in superior shock compaction effects, delivering sand hardness that is high and uniformly distributed, with an average hardness of 85-90 (as per B hardness meter). The sand consumption is minimal, ranging from 20 to 30mm, with an impressive sand eating ratio of H:B=2~3. Even the vertical surface hardness of the cavity exceeds 80.
This Hydraulic Multi-Piston Moulding Machine is an engineering marvel composed of a sturdy machine body, a meticulously designed table, a hydraulic piston contact box, an advanced mould starting mechanism, and a sophisticated pneumatic piping system, all working in harmony.
1. The robust machine body, crafted as a solid hollow frame workpiece, supports the swivel arm press head. During compaction, the swivel arm anchors the machine body, ensuring the press force is effectively borne. The machine body is bolted together with the shock mechanism, and the press head is mounted on the swing arm. It features a screw elevator to adjust the press head's distance to the sand box according to its height.
2. The working table, cast and shaped from high-quality ductile iron, is tailored to fit the specific dimensions of the sand box, ensuring seamless operation and reliability.
3. The Hydraulic Piston Contact Box integrates a multi-contact body, pneumatic multi-contacts, and four pull hooks. The pneumatic multi-contacts function through a unique structure where compaction inlet air is directed to the multi-contact body and internal air cavity, and also into the lower cavity of the fixed piston. This strategic design delivers substantial pressure force by leveraging the area difference under air pressure.
4. The mould starting structure is a marvel of engineering, consisting of dual mould starting cylinders, a connecting rod, balance shaft, mould starting table, and mould starting rod. When activated, the system seamlessly lifts the sand box and initiates the mould with precision and efficiency.
5. The Pneumatic Piping System is meticulously designed to enhance machine performance. It purifies input compressed air through an air filter, removing water and impurities. An oil mist injector adds lubrication, ensuring smooth operation of each pneumatic component. All machine actions are effortlessly controlled through a hand-pull valve console, embodying precision and user-friendly operation.
