AI Technical Summary

Technical Problem

Existing sand mold drying equipment has low drying efficiency, especially due to poor penetration of molding sand inside the sand box, resulting in low drying efficiency.

Method used

The system employs components such as a drying chamber, electric heating tube heating layer, pouring port, main air duct, valved branch pipe, branch pipe, return air fan, return pipe, and valved return branch pipe. High-temperature hot airflow is directly injected into the sand box through an external hose and circulated, thus achieving direct drying of the molding sand inside the sand box.

Benefits of technology

It improves the drying efficiency of molding sand inside the sand box, enhances penetration ability, avoids waste of hot airflow, and is compatible with multiple sand boxes used simultaneously, preventing the system pressure from being too low and affecting hot air circulation.
