When the mold is cleaned, the water nozzle as a component connected to the external water pipe is easy to become a channel for debris to enter the mold interior. Once debris enters the cooling pipe inside the mold through the water nozzle, it will accumulate in the cooling pipe, reducing the flow area of the cooling pipe and affecting the flow rate and flow of the cooling liquid, thereby weakening the cooling effect. This not only reduces the molding quality of plastic products, resulting in defects such as deformation and size deviation, but also may prolong the production cycle and increase the production cost due to the reduced cooling efficiency.
