AI Technical Summary
The existing injection mold nozzle structure is prone to clogging during use due to the solidification of thermosetting plastics, which affects production efficiency and increases replacement costs.
A cooling structure is designed at the nozzle, which surrounds the nozzle through a water flow diversion channel and a flow guide sleeve. The cooling liquid is used to maintain the nozzle temperature and prevent the thermosetting plastic from solidifying.
It effectively prevents thermosetting plastics from solidifying during injection molding, improving production efficiency and reducing the frequency and cost of nozzle replacement.
