AI Technical Summary

Technical Problem

Traditional planetary carrier molds are prone to deformation and damage when subjected to high pressure and impact, and the lack of protective structure makes the edges and corners easily damaged, affecting the service life of the mold and the forming accuracy of the planetary carrier.

Method used

It adopts a multi-layer board structure with interlaced fiber design in each layer of thin board. Angle iron is wrapped around the four sides of the mold plate. The modular components are detachably connected. The inner wall of the cavity is coated with a wear-resistant coating. The combination of the strength of the angle iron and the wear-resistant coating improves the overall strength and wear resistance of the mold.

Benefits of technology

It enhances the overall strength and stability of the mold, reduces the risk of deformation and damage, extends the service life of the mold, and improves the forming accuracy and production efficiency of the planetary carrier.
