AI Technical Summary

Technical Problem

When the injection molding cycle ends or the machine is stopped, the molten plastic that is not discharged in time in the pipeline cools and solidifies, which prevents the plastic raw material from entering the mold through the pipeline in the subsequent injection molding process, affecting the continuity of production.

Method used

The system employs a pipe heating assembly, which generates heat through a heating rod and conducts it to the injection pipe via a heat-conducting ring. This melts the solidified plastic material, and combined with a pipe auxiliary unblocking device, it unclogs blockages, ensuring that the plastic material can smoothly enter the mold.

Benefits of technology

Quickly resolve injection molding pipe blockage issues, ensure the continuity and stability of injection molding production, extend the lifespan of heating components, reduce downtime, and improve production efficiency.
