Casting process of part structure

1. Casting process of part structure
Refers to the structure of the parts should meet the requirements of casting production, easy to ensure the quality of casting, simplify the casting process and reduce the cost.
2. Investigate the basis of the casting process of the part structure
1. Avoid defects
The wall thickness must not change dramatically
Design the casting to avoid the shape of the casting shrinkage blocked during cooling
Castings shall be designed to avoid large horizontal planes
The casting strength shall not be weakened when designing the casting window
Cings should not be designed in shapes that are difficult to clear sand
Do not forget the loading part during the design of the machining castings
Do not neglect to minimize the processing area when designing castings with processing surfaces
Simplify the casting process aspects
When designing a heavy and large casting, do not forget to design the lifting measures on the casting
When designing the castings, the arrangement of the ribs shall not hinder the molding process
The design shall not prevent sand clearing or weakening core strength
Do not hinder the formwork and shape when designing the casting abutment
When designing castings, attention should be paid not to use multiple classification surfaces
Design castings shall minimize the cores
The designed casting shall be avoided as far as possible
The designed casting shall not cause the instability of the type core support
Material aspect
The reinforcing ribs of grey cast iron should not be placed on the stretched side
Reasonable and unreasonable structure of ductile iron cast parts (cylinder block)
Malleable and cast iron bearing holder
Copper alloy three-way valve body casting
