China Foundry Machinery Sand Casting Multi piston Moulding Machine For Manhole Cover Production
This China Foundry Machinery Sand Casting Multi piston Moulding Machine For Manhole Cover Production line can be used in all kinds of foundry workshop clay sand upper and lower box modeling, can be used by single machine or mechanized assembly line, but also can be used by semi-automatic line.
The biggest characteristics of this machine are three:
1, pneumatic multi-piston compaction, no oil leakage, moderate specific pressure, no special requirements for molding sand, a large number of pistons (48pcs or more ), suitable for complex model modeling.
2. When the machine is compacted, the frame is not subjected to force, but is hooked to the worktable by four pull rods hanging from the side of the multi-pistons body. With the multi-contact extending downward, compaction is carried out. If the contact, hook, sand box, mold plate, If the worktable is regarded as a system, this kind of compression strength is internal force or internal force compaction.
3, compaction, contact compaction sand mold on the one hand, at the same time with the worktable shock (detached from the frame, the frame is not vibrated). Therefore, the compaction effect of shock is good, the hardness of sand mold is high and uniform (the average hardness is 85 × 90, B hardness is measured), the amount of sand eaten can be as small as 20 × 30 mm, the ratio of sand to sand is H ≤ B ≤ 2 ≤ 3, and the hardness of the vertical surface of the mold cavity can still reach more than 80. This machine adopts spring full buffer pneumatic microshock mechanism, so there is no special requirement for foundation. The die starting adopts connecting rod synchronous shaft structure, pneumatic oil speed regulation, good synchronism of starting die, easy speed control, and compaction contact is a single independent cylinder. The number of working pistons can be adjusted with the sand box.
specification:

Since its founding in 1998 as Qingdao Huaxin Group, the mission of qingdao huaxin group has been to develop the most innovative solutions possible for the automation of green sand moulding, sand core making machine, sand preparation and shot blasting processes throughout the foundry industry. Continuous technological improvement and innovation have earned nearly 20 intellectual property rights in China.
Today, with nearly 5,000 sand moulding machines and shot blasting systems installed around the world, and its sales and service operations are spread all over the world. Our single focus is, has always been, and will always be the foundry industry.
Qingdao Huaxin Group has over 20 years history In China. It is located in Binhai Industrial Park, Huangdao Area, Qingdao city,China. It is covered an area of sixty-six thousand six hundred and sixty-seven Square meters. We have produced foundry machines more than 1000 types, so we have rich experience in sand casting production machines. The casting production line is Automatic horizontal static pressure molding line, Auto shell molding line, Furan resin sand automatic molding line, Green sandl processing production line(Sand Preparation); the newest patent machine-continuous sand mixer,pouring machine, popular standard machine are Jolt squeeze molding machine, pneumatic multi-piston molding machine, all kinds of cold core / hot core box core shooting machine, various shot blasting machines. We provide excellent supporting equipment and services for China's foundry, shipbuilding, automobile, locomotive, machine tool and other industries. We design and manufacture various non-standard special casting machines according to user needs.
