AI Technical Summary
The existing mold replacement process is cumbersome and time-consuming, resulting in low production efficiency, high labor costs, and impact on product quality.
The module adopts a snap-fit structure with a modular mounting slot, sliding mounting pin and positioning pin. The injection module can be replaced by loosening the second fixing bolt, avoiding the need to disassemble the entire mold.
Significantly shorten product changeover time, reduce operational complexity, improve production efficiency, reduce labor costs, and ensure product molding quality.
