[0028] When in use, the two hydraulic cylinders 3 can be started by the controller to drive the upper mold base 4 to move downward until the upper mold base 4 is tightly fitted with the lower mold base 7. At this time, the molding mold 8 is located inside the molding groove 5, and then the liquid silicone raw material can be injected into the molding groove 5 through the injection pipe 6 to wait for molding. After the molding is completed, the two hydraulic cylinders 3 can be started to drive the upper mold base 4 to move upward, and then the liquid silicone molded part can be removed. When it is necessary to clean the residue attached to the molding mold 8, the driving motor 161 and the blower 211 can be started by the controller, wherein the driving motor 161 will drive the worm 162 to rotate, and then drive the rotating shaft 15 and the turntable 17 to rotate through the worm gear 163. During the rotation of the turntable 17, the moving frame 20 and the high-pressure nozzle 212 will be driven to reciprocate back and forth through the lever 18, and the blower 211 will supply air to the high-pressure nozzle 212 through the air supply pipe 213, and then spray through the high-pressure nozzle 212, and then the servo motor 161 can be started by the controller.

During the rotation of the threaded rod 10, the moving block 11, the mounting plate 13 and the high-pressure nozzle 212 are driven to move to the left as a whole, so that the high-pressure nozzle 212 sprays high-pressure gas while moving back and forth and moving to the left, so as to blow up the residue attached to the molding mold 8, thereby automatically cleaning the molding mold 8, without manual cleaning, thereby reducing labor intensity and facilitating the use of the user. After the cleaning is completed, the driving motor 161 and the blower 211 can be turned off by the controller, and the servo motor 121 can be started to rotate in the opposite direction, so as to drive the threaded rod 10 to rotate in the opposite direction.

[0029] In summary, the liquid silicone molding mold starts the driving motor 161 and the blower 211, wherein the driving motor 161 drives the worm 162 to rotate, and then drives the rotating shaft 15 and the turntable 17 to rotate through the worm gear 163. During the rotation of the turntable 17, the moving frame 20 and the high-pressure nozzle 212 are driven to move back and forth through the lever 18, and the blower 211 delivers air to the high-pressure nozzle 212 through the air supply pipe 213, and then sprays out through the high-pressure nozzle 212. At this time, the servo motor 121 can be started to drive the driving gear 122 to rotate, and then the driven gear 123 can be used to drive the threaded rod 10 to rotate, and the threaded rod 10 is rotated during the rotation. This will drive the moving block 11, the mounting plate 13 and the high-pressure nozzle 212 to move to the left as a whole, so that the high-pressure nozzle 212 sprays high-pressure gas while moving back and forth and to the left, so as to blow up the residue attached to the molding die 8, thereby automatically cleaning the molding die 8 without manual cleaning, thereby reducing labor intensity and facilitating user use. It solves the problem that after injection molding, the existing molding die usually requires workers to hold a hair dryer to blow the lower mold, so as to blow out the residue on the lower mold and avoid residual residue on the lower mold, which will cause defects in the next molding, thereby increasing the labor intensity of the workers and being unfavorable for use.
