AI Technical Summary

⚠Technical Problem

Existing forced reset mechanisms for plastic mold machinery require the hydraulic telescopic rod to rise and simultaneously overcome the adhesion of the workpiece and the inertia of the component, which can easily lead to reset delays, affecting production rhythm and potentially causing workpiece damage or mold alignment deviations.

⚗Method used

Design a forced reset mechanism including a return spring and a connecting rod. The spring force of the return spring quickly lifts the fixed plate, driving the connecting rod to rise synchronously, thus achieving instantaneous forced reset. The precise guidance of the side plate and the connecting rod ensures accurate mold alignment, and the anti-slip pads on the bottom plate enhance the stability of the equipment.

🎯Benefits of technology

It achieves rapid and stable mold reset, avoids reset lag, ensures continuous production rhythm, reduces the risk of product defects and mold damage, and improves production efficiency and reliability.
