AI Technical Summary

Technical Problem

Existing injection molding assembly machines require manual positioning of the injection molded parts, which necessitates manual adjustment of the position before each pressing, resulting in deviations and affecting product quality.

Method used

The system employs a motor-driven bidirectional screw and limiting plate system. The screw rotation drives the limiting plate to move synchronously, ensuring stable positioning of the plastic part. Precise alignment is achieved through the cooperation of elastic elements and guide rods.

Benefits of technology

It enables automatic positioning of injection molded parts, ensuring precise alignment during assembly, improving product quality and equipment stability, and reducing frictional wear.
