AI Technical Summary

Technical Problem

The existing low-pressure casting molds for aluminum alloy steering knuckles cannot set the cooling water channels in the optimal position due to the presence of the ejection mechanism, resulting in the inability to effectively solve the problems of cooling speed and porosity.

Method used

The design employs an ejector insert and induction coil, eliminating the traditional ejector mechanism. The ejector insert is heated by the induction coil to cause thermal expansion and contraction, enabling flexible arrangement and optimal positioning of the cooling water channels. The heating temperature is controlled by a temperature probe.

Benefits of technology

The optimal location of the cooling channels was achieved, ensuring the best cooling rate and porosity control in aluminum alloy casting, improving the quality of aluminum alloy blanks and reducing production costs.
