AI Technical Summary
Technical Problem
Existing injection molding machines are inefficient and lack automation when molding plastic lunch boxes.
Method used
Design an injection mold that includes an active traction device, a driven gear, a traction chain, and an injection mold body. The active gear is driven by a servo motor to drive the driven gear and the traction chain, realizing the cyclic transport of multiple injection molds. The injection molding is performed by the cooperation of a thermoforming platen and a traction roller.
Benefits of technology
It improves the automation level of injection molds, enables the cyclical coordination of multiple injection molds, and enhances production efficiency.
