Characteristics of iron mold sand covering production line

1. Horizontal classification, the shooting head moves automatically to add sand, and the sand shooting plate does not require water cooling.

2. Gas/liquid/electric drive, smooth.

3. The sand covering machine is controlled by PLC and can achieve single machine automation.

4. The flipping and closing mechanisms are operated manually, resulting in low costs. Mechanical operation can also be chosen to reduce labor intensity.

5. Adopting hydraulic insertion vibration for sand dropping, lifting, and easy maintenance.

6. Use control components to make the system stable.

7. We can design and provide sand covering molds and iron sand boxes that are compatible with the equipment for users.

Due to the high cost of tooling for sand covered casting of iron molds and the difficulty of modification. Therefore, the design of this process requires a one-time success. At present, some production enterprises have a high scrap rate of castings due to improper design of process fixtures. In recent years, our institute has completed the computer numerical simulation project of solidification process of iron mold sand covered casting nodular iron parts, which can optimize and compare multiple process schemes. However, due to the difficulty in obtaining accurate thermal property parameters and some simplification processes, there is still a long way to go to achieve meaningful optimization design.
