AI Technical Summary

⚠Technical Problem

When the demolding mechanism of traditional motorcycle side panel injection molds uses rigid push rods for ejection, scratches, micro-cracks, or even localized fractures are easily generated on the surface of carbon fiber side panels, affecting product quality and increasing production costs.

⚗Method used

The ejection assembly, which combines a buffer disc spring and a tension spring, uses a hydraulic actuator to drive a push rod to push the connecting plate. The buffer disc spring buffers stress during the ejection process. Combined with the design of a quick-connect water-cooling pipeline, the water pipes are quickly connected using limit balls and limit grooves.

🎯Benefits of technology

This effectively avoids scratches and microcracks on the carbon fiber side plates during the ejection process, improves product surface quality, and increases the installation efficiency of the mold cooling system.
