[0002] Sand casting is a traditional casting method suitable for producing parts with complex structures and high dimensional requirements, such as bearing seats. The following are the detailed steps for manufacturing bearing seats using sand casting technology: 1. Design the sand mold: Design the sand mold according to the structure of the bearing seat to ensure that all details can be accurately reflected in the sand mold; considering the shrinkage during the casting process, some dimensions may need to be increased to compensate for the shrinkage of the final product; 2. Make the sand mold; 3. Cast the metal to melt to the appropriate temperature and inject it into the sand mold through the gate. Pay attention to controlling the casting speed and metal liquid level to avoid bubbles and splashes; 4. Cooling and solidification; 5. Cleaning and trimming;

[0003] The above-mentioned sand mold casting method has the following defects in actual work:
