AI Technical Summary

Technical Problem

Existing die-casting equipment requires loosening or tightening multiple bolts one by one when changing molds. The operation relies on wrenches and manual experience, resulting in low mold-changing efficiency and uneven stress on the mold. Long-term use may lead to problems such as mold cavity misalignment and flash.

Method used

The clamping system, which uses a servo motor and a two-way trapezoidal lead screw, combined with a hydraulic telescopic cylinder and a guide rod, enables rapid and precise docking and stable clamping of the upper and lower molds. The self-locking property of the servo motor and the trapezoidal lead screw ensures uniform force transmission, while the hydraulic telescopic cylinder and guide rod provide guidance and limit.

Benefits of technology

It improves mold changing efficiency, ensures mold alignment accuracy, avoids mold cavity misalignment, and enhances production efficiency and product quality.
