AI Technical Summary

Technical Problem

Existing casting molds lack flexibility during the cooling and shrinkage of castings, leading to stress concentration and cracking. Furthermore, the overall welded structure is susceptible to temperature differences and impacts, shortening its service life.

Method used

The column and base are designed with detachable flanges, and the evenly distributed rectangular gaps and vents allow the mold to retract during casting shrinkage. The relative movement of the column and base is achieved through bolted connections, reducing stress concentration.

Benefits of technology

It improves the mold's resilience, reduces internal stress concentration in castings, lowers product scrap rate, and extends the mold's service life.
