AI Technical Summary

Technical Problem

Existing single-station and dual-station iron mold sand casting equipment cannot meet the production needs of multi-piece mold combinations for large castings, and cannot simultaneously achieve high precision, low labor intensity and high degree of mechanization in sand casting.

Method used

A closed-loop large-scale iron mold sand coating molding line was designed, including a mold closing station, iron mold and model conveying track, iron mold and model heating furnace, iron mold sand shooting and sand coating device, iron mold and model mold separation mechanism, etc. It adopts a through-type sand shooting and sand coating and mold separation method, combined with a self-propelled electric trolley and track changing transition transfer trolley mechanism to realize the automated sand coating molding of multiple large iron molds.

Benefits of technology

It enables high-quality, low-cost production of large casting molds, with low labor intensity and convenient equipment installation. It meets the needs of automated and intelligent mass production of large castings and is suitable for multi-mold combinations of large castings such as wind power castings.
