AI Technical Summary

Technical Problem

Existing injection molding equipment has low precision in adjusting injection pressure, making it difficult to accurately match different materials and molding stages, resulting in defects such as material shortage, shrinkage marks, and flash in products.

Method used

The system employs a locking mechanism by pulling the adjusting rod to engage the adjusting cylinder. Combined with the cooperation of the spiral guide groove and the adjusting rod, it achieves precise control of the adjusting cylinder's displacement and adjusts the injection pressure by changing the cross-sectional area of ​​the flow cavity.

Benefits of technology

It enables precise adjustment of injection pressure, adapting to the needs of injection molded parts of different materials and structures, reducing melt leakage, and improving product quality and safety.
