AI Technical Summary
Replacing guide pillars in existing metal die-casting molds is complex, costly, and unstable. They are prone to loosening or falling off, which can damage the equipment and affect production efficiency and quality.
A quick-change device and limiting mechanism were designed, including an unlocking sleeve, a connecting rod, a locking block, a locking rod, and a limiting sleeve. By simplifying the operation process and ensuring precise fit, the guide post can be easily replaced and stably installed.
It improves the convenience and efficiency of guide post replacement, ensures the stability of the guide posts and the safety of the equipment, reduces labor costs and operational complexity, and reduces the risk of equipment damage.
