The machining allowance is retained based on the deformation pattern of the casting mold, so that the mold will not be scrapped due to mold deformation after quenching. For each transition angle of the mold, curved or smooth transitions should be made as much as possible. Compare the improved line contour with the original line contour.

The radial groove is added at the front end of the mold inlet. Please note that the trunking should not be too thin or too deep, as it may cause wire sticking and breakage. The groove and mold can also be curved or smoothly transitioned, which plays a certain role in reducing the stress generated by casting and can also improve the lubrication effect. For molds with particularly complex shapes, a feeding structure can be used to ensure uniform cooling during the quenching process.

These improvements in the mold have reduced the workload of the factory, increased revenue, and laid a solid foundation for the factory. Of course, this also benefits the quality and service life of casting molds.
