When the helical teeth of the second rotating member 410 and the first rotating member 49 disengage from each other, the third spring 48 resets and drives the first rotating member 49 to move forward and reset. The telescopic end of the telescopic member 412 extends and resets. When the electric slide rail 17 drives the support rod 18 to move backward, the connecting member 41 is threadedly connected to the screw rod 42, so that the screw rod 42 rotates counterclockwise, and the screw rod 42 drives the second rotating member 410 to rotate counterclockwise. The right-angled surfaces of the helical teeth between the second rotating member 410 and the first rotating member 49 abut against each other, and the second rotating member 410 drives the first rotating member 49 to rotate counterclockwise. The first rotating member 49 drives the telescopic member 412 and then drives the turntable 47 to rotate counterclockwise. The turntable 47 rotates counterclockwise with The movable piston 46 moves up and down. When the piston 46 moves downward, the piston 46 squeezes the gas at the bottom of the air storage box 44, and the gas at the bottom of the air storage box 44 enters the liquid storage box 45, squeezing the release agent in the liquid storage box 45. The release agent enters the hose 43 and is sprayed out through the sprayer 4. Because the nozzle on the sprayer 4 is bidirectional, the upper mold 15 and the lower mold 16 can be sprayed with the release agent. When the piston 46 moves upward, a negative pressure is formed at the bottom of the air storage box 44, and the outside air will enter the air storage box 44 through the one-way valve at the bottom of the air storage box 44. At the same time, a small amount of gas will enter the air storage box 44 from the liquid storage box 45. When the support rod 18 moves to the rear end of the electric slide rail 17, people close the electric slide rails 17. The above operation is performed by The support rod 18 drives the connecting member 41 to move backward, and the connecting member 41 is threadedly connected to the screw rod 42. The screw rod 42 rotates counterclockwise to drive the second rotating member 410 to rotate counterclockwise, and the second rotating member 410 drives the first rotating member 49 to rotate counterclockwise, and the first rotating member 49 drives the telescopic member 412 and then drives the turntable 47 to rotate counterclockwise. The rotation of the turntable 47 causes the piston member 46 to move up and down. When the piston member 46 moves downward, the piston member 46 squeezes the gas in the air storage tank 44, so that the gas enters the liquid storage tank 45 and squeezes the release agent, so that the release agent enters the hose 43 and is sprayed out through the sprayer 4. The nozzle of the sprayer 4 is bidirectional, so that the upper mold 15 and the lower mold 16 can be sprayed with the release agent, thereby replacing people's manual spraying, saving time and effort.
