Location >> Automatic line of high pressure multi-piston squeeze moulding
|
Main characteristics of the moulding line： Air blowing pre-compaction plus multi-piston high pressure squeezing moulding technology is adopted to ensure high sand mould hardness, uniform mould compactness, low mismatch, precise castings and high yield. Average mould hardness is 90-95, hardness difference on the same surface is <±5,mismatch is <0.3mm. Hydraulic multi-piston squeeze heads are used for squeezing, and the pressure can be adjusted by proportional decompression valve. Specific squeeze pressure is sectioned and adjustable, with a maximum value of 1.5MPa. Control system is equipped with engineer station, main operation station and multiple stand-by sub-stations, each fitted with man-machine interface. Advanced technologies such as industrial personal computer, numerical control machine tool, PLC field bus, servo valve, proportional valve, frequency control, automatic detector and computer monitor are used. Whole production line operations comply with principle of combinating electrical control, hydraulic and pneumatic transmission. Key components are imported to guarantee stable and reliable operation of the production line. It has advantages of full automation, high productivity, precise casting, small area coverage and low energy consumption. It is the mostly advanced moulding line at present. Suitable for volume production of top grade castings, it has been widely applied in production of automobile castings and other grey cast iron, ductile iron and steel castings. |

Main components of the moulding line： It is comprised of moulding, core setting & flasks closure, pouring, cooling and shakeout sections. It includes static pressure moulding machine, whole set of auxiliary devices, mould conveyor, electrical control system, hydraulic system, and technological equipment such as flasks and pattern plate bolsters. Static pressure moulding machine is made up of lifting working table, blowing pre-compaction device, multi-piston squeezing device, louver type sand feeder, pattern plate rotation device and upper machine frame traveling gear. It can complete quantified sand feeding, moulding, pattern drawing and pattern plate exchange processes. Auxiliary devices of moulding line include punch-out device, flasks separator, flask lifting, lowering and transfer device, flask rollover device, cleaning device, flasks closure device, flasks fastening & loosening device, vent hole drilling device and sprue milling device, which can carry out auxiliary processes of the whole moulding line. Mould conveyor is comprised of transfer car, indexing device, cushioning device, pallet car and positioning device which can automatically transfer moulds. Control system is equipped with engineer station, main operation station and multiple stand-by sub-stations, each fitted with man-machine interface. Advanced technologies such as industrial personal computer, numerical control machine tool, PLC field bus, servo valve, proportional valve, frequency control, automatic detector and computer monitor are used. Key components are imported. Pouring system: Automatic (or semi-automatic) pouring machine can be used. Ventilation & dust collecting system is for ventilation and dust removal at pouring and cooling sections. |
