AI Technical Summary
In traditional multi-color injection molding technology, multi-nozzle systems are complex and costly, while rotary or valve needle switching mechanisms have low color-changing efficiency and are prone to color mixing, requiring frequent cleaning.
The device employs a hot runner nozzle for rapid color changing. It uses a hydraulic rod to drive the partition plate and guide tube to slide, achieving a single hydraulic action to complete the two-color injection molding switch. The structure is simple, and the mechanical linkage automatically completes the color switching.
It enables fast and simple color switching, reduces equipment complexity and manufacturing costs, and avoids color mixing.
