[0082] The working principle of the present invention is as follows: before injection molding, by setting the torsion spring and the stop block 41, the lower mold 2 can be kept in a vertically upward position in a non-stressed state, and during injection molding, the upper mold 11 rotates to the top of the lower mold 2, and then the upper mold 11 and the lower mold 2 are fully close to each other, and the injection plastic is injected into the injection mold cavity of the automobile door panel. After the injection plastic is fully injected, the cooling liquid is circulated in the cooling cavity 38, and then the automobile door panel injection mold cavity is quickly cooled and shaped.

After the vacuum suction nozzle 16 completes vacuum absorption of the door panel, Under the rotation drive of the rotating frame 7, the vacuum suction nozzle 16 drives the sucked door panel to move to the annular unloading belt 13. The annular unloading belt 13 transports the molded door panel on the annular unloading belt 13 to the designated production line according to the test results of the auxiliary liquid spraying and the test components. When the automobile door panel in the injection mold cavity is unloaded, the upper rotating frame 7 rotates. In the process of the vibration plate 27 approaching the lower mold 2, the missing bevel gear ring 28 is firstly connected with the driven bevel gear 30 for transmission, and drives the hinge shaft 5. When the vibration plate 27 moves to the top of the lower mold 2, the lower mold 2 flips 180°. After the lower mold 2 flips 180°, the automobile door panel is injected. The mold cavity is set vertically downward. After the automobile door panel injection mold cavity is set vertically downward, the limit notch 29 is set, so that the limit frame 6 loses the limit function. Thereafter, the vibration motor 33 outputs the vibration frequency at the set power. After the vibration motor 33 outputs the vibration frequency, the residual mold material in the automobile door panel injection mold cavity can be vibrated and removed, thereby effectively realizing the automatic cleaning and automatic impurity removal of the automobile door panel injection mold cavity after a single injection, thereby effectively ensuring the injection molding effect and injection molding quality of the device, and during cleaning, the air cleaning nozzle 35 discharges air at high pressure, thereby effectively improving the cleaning strength and cleaning effect of the automobile door panel injection mold cavity;

[0083] After the unloading, flipping and cleaning operations of the automobile door panel in the automobile door panel injection mold cavity are completed, under the driving action of the screw lifting module 42, the axial screw transmission module 24 and the longitudinal screw transmission module 26, the shaft shifting frame 25 moves along the specified trajectory, thereby realizing the uniform spraying of the release agent in the automobile door panel injection mold cavity.
