At this time, the mold release agent in the material storage tank will be delivered to the nozzle body 2 through the hose and the material inlet 12. At the same time, the high-pressure air source will also deliver the compressed air into the nozzle body 2 through the hose and the air inlet 13, and then blow it out through the spray port 11. The mold release agent will be taken out from the spray port 11 along with the compressed air under the high pressure of the compressed air, thereby realizing the automatic spraying of the mold release agent, until the mold release agent is completely covered in the heterogeneous cavity of the mold, and the air inlet solenoid valve at the air inlet 13 is closed. At this time, the mold release agent will not be taken out by the compressed gas;After the release agent is sprayed, the air inlet solenoid valve at the air inlet interface 16 is opened through the control box or controller. At this time, the compressed air will be sent into the lower frame of the fixed bracket 1 through the hose and the air inlet interface 16, and then blown out through the blowing port 15.
