Customized cast steel parts: The design of the cast steel structure should not only meet the requirements of the machine equipment itself and mechanical processing, but also comply with the basic requirements of the casting process.
The design of steel casting structures should facilitate the manufacturing of models, core boxes, and shapes
The shape of the casting should strive for simplicity to facilitate mold removal, and the casting parting surface should be as flat as possible with the minimum number of parts;
When manufacturing small castings, try to avoid or minimize the use of cores in the inner cavity.
For the inner and outer sides of cast steel parts and reinforced ribs, a certain structural slope should be set in the direction of mold lifting.
The convex part on the casting should not differ too much from the casting body. It is best to take several convex parts that are close to each other at the same height and on the same surface, and connect them into a whole convex part.
Reduce the tendency to produce casting defects:
1. Try to avoid castings with large horizontal surfaces as much as possible
2. The casting structure should be designed to allow for unobstructed shrinkage during cooling as much as possible
3. For locally thick sections of castings, hollow or cast hole structures should be used as much as possible, and reinforced with appropriate ribs.
4. The casting holes on the flat wall of the casting should be reinforced with convex edges to reduce wall thickness
5. The connection between casting walls should strictly prevent sharp corners and metal accumulation. The transition between thick and thin walls should be avoided to prevent sudden changes, so as not to cause hot spots and stress concentration, resulting in hot cracks, pine, etc
6. There should be several connecting columns for large interlayer cavities such as water and gas circuits in castings.
7. The wall thickness of cast steel parts should strive for uniformity to prevent shrinkage and hot cracking. When it is necessary to ensure sequential solidification conditions, the wall thickness should be varied in one direction as much as possible. When simultaneous solidification conditions are required, equal cross-sectional wall thickness should be maintained as much as possible to ensure good formability of the castings, and the minimum wall thickness of the castings should not be lower than the allowable value.
