Shell casting production line
Coated sand shell molding line can also be called shell molding line or steel shot shell molding core molding line. Compared with ordinary sand casting, it has less equipment investment, small floor space, simple process and high production efficiency. High, small amount of casting sand, low workpiece rejection rate, good sand disintegration, less dust at the production site, low noise, etc., thus causing environmental pollution. "This new method can make the casting surface smoother, more accurate in size, and reduce Or does not require mechanical processing, which can shorten the production cycle, save metal materials, and reduce costs. It is widely used in valves and pumps, butterfly valve discs, valve bodies, pump bodies, pump covers, pump bearing seats, open impellers, semi-open impellers, closed impellers, etc. type impeller, cam lock coupling, ball milled cast iron valve body, centrifugal pump body1. Automobile: drive shaft, control arm, gearbox housing, gearbox cover, wheels, hubs, filter housing,
2. Truck: rocker arm, gearbox, drive axle, drag eye, engine block, engine cover, joint bolts, crankshaft, camshaft, oil pan,
3. Hydraulic system: hydraulic pump, hydraulic cylinder, cycloidal pump casing, blades, bushings, hydraulic oil tank,
4. Agricultural machinery: gearbox housing, torque rod, engine block, engine cover, oil pump housing, bracket
5. Railway trains: shock absorbers, buffer bodies, cones, wheels, braking systems, handles,
6. Engineering machinery: gear pump, gearbox housing, gearbox cover, flange, bushing, boom cylinder, support frame, hydraulic oil tank,
7. Logistics equipment: heavy cast iron wheels, industrial casters, cast iron casters, hydraulic cylinders
Production of various complex castings such as automobile cylinder blocks, cylinder heads, gears, intake manifolds, various pipe fittings, pump bodies, etc.
Production principle:
First use a core-making machine to make the product into a shell shape, then put the shell shape into a sand box, fill it with steel shot or dry sand, and then cast it after vibration and compaction. After pouring, it circulates through the transfer vehicle to the turning machine for the next cycle. It is especially suitable for batch and mass production of small and medium-sized castings of various metals.
Work flow' Coated sand → Core shooting machine shell → Shell mold bonding → Pressing → Put in the casting box → Shell mold capping → Quantitative addition of steel shot → Vibrating steel shot tightness → Casting → Cooling → Opening → Steel Pills-Sand-Castings→Turn over and separate→Extract castings
1. Core swinging and core setting
Use manual or mechanical core setting device
Pre-fill some steel shots in the sand box to ensure that the sand core and the pouring riser are at the same height. After the core is completed, it is filled with steel shot and vibrated.
Pouring machine, ring gauge casting, hanging castle casting, etc.
After the casting is completed, the sand box is transferred to the cooling area by the shuttle device, and the cooling time is set according to the actual needs of the product.
After reaching the set cooling time, the sand box is transferred to the turning station to complete automatic turning.
Castings, waste sand, steel shots, and iron blocks enter the shakeout machine uniformly, and the castings are vibrated and transported into the hopper.
Casting, ferrying, turning over, cooling and other work stations adopt semi-closed or closed dust/odor removal
