AI Technical Summary
Existing motor resin injection molds suffer from uneven cooling during the cooling process, especially in complex-shaped motor resin parts such as deep cavities, thin walls, or irregular structures. This results in low mold utilization and an inability to meet the needs of large-scale production.
The design employs a combination of brackets, heightening plates, cooling mechanisms, and fixing mechanisms. It utilizes eccentric wheels and rollers to drive the fan in reciprocating motion, expanding the airflow range. Combined with a precisely positioned mold connection method, it achieves rapid and uniform cooling.
It enables rapid and uniform cooling of complex-shaped motor resin components, improves mold utilization, enhances production efficiency, and meets the needs of large-scale production.
