I. Simple description
V process casting machine is called vacuum seal casting molding machine. It's a kind of dry sand casting molding machine which adopts no adhesive. Based on the pressure produced by the vacuum pump, it takes use of the EVA film to make a vacuum sealed condition. Then the dry sand will be tightened, and getting a mould. The finished casting's quality is very good after pouring. Our V process casting machine has been ranked as Cleaner Production Directory because of its high sand recovery rate, high material utilization as well as its eco-friendly advantage. So far, V process has been successfully applied in the construction machinery counter weight, petroleum machinery(including crank, reduction case, counterweight), belt pulley, swing bolster, axle, brake drum, piano plane, manhole cover, high manganese steel lining board.
Different types of V method molding production line can be designed according to customers' actual production requirements: trolley type V method molding line, pass-through type V method molding line, shuttle type V method molding line, motorized roller type V method molding line, rotary table V method molding line, etc.
II. Brief introduction of V process molding line
III. Structures of the production line
The whole casting production line is divided into two parts: sand processing unit and molding unit.
The main equipment of the sand reclamation unit includes: sand shakeout dust hood, sand shakeout grid and transition sand hopper, moulding box return roller , vibrating conveyor sand screen machine, suspended magnetic separator, plate chain elevator, sand storage, boiling cooling equipment, bucket elevator, belt conveyor, sand discharging device, dust collecting system, electric control system, etc.
The main equipment of the modeling unit includes: film laminating machine, film spreading platform, drying device, sand feeding system, mobile vibrating table, manipulator, core setting and moulding flat trolley, pneumatic control system, electric control system, hydraulic system, vacuum system,etc.
Advantages:
Castings have high dimensional accuracy, clear contours and smooth surface.
High metal utilization. Improve metal utilization, steel castings can be increased by 20%, iron castings can be increased by 25%.
Simple equipment and low investment. In addition to the addition of a vacuum pump and the use of a special sand box, the other equipment of the V method moulding is relatively simple. The sand mixer and some auxiliary equipment can be omitted, the investment cost is low, and the equipment maintenance is convenient.
Save raw materials and power. Because the V method uses dry sand, it is easy to shake off the sand, and the sand recovery rate can reach more than 95%. The use of V method moulding consumes less power, only 60% of the green sand method, and can reduce labor by 35%.
Long service life of the pattern and the sand box.Because the pattern is protected by plastic film, the drafting force is very small, there is only slight vibration and it is not affected by high temperature and high pressure, so the pattern is not easy to deform and damage.
Improve the working environment
