Then, the upper mold and the lower mold are fully fitted together, and the injection molded material is injected into the automobile door panel injection molded cavity.

Thereafter, the vibration motor outputs the vibration frequency with the set power. After the vibration motor outputs the vibration frequency, the residual mold material in the injection mold cavity of the automobile door panel 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 molding, thereby effectively ensuring the injection molding effect and injection molding quality of the device, and during cleaning, the air cleaning nozzle discharges high-pressure air, thereby effectively improving the cleaning strength and cleaning effect of the automobile door panel injection mold cavity.

[0025] 5.

[0081] When the automobile door panel in the injection mold cavity of the automobile door panel is completed, the upper turntable 7 rotates. In the process of the vibration transmission plate 27 approaching the lower mold 2, the missing bevel gear ring 28 is first connected to the driven bevel gear 30 for transmission, and drives the hinge shaft 5. When the vibration transmission plate 27 moves to the top of the lower mold 2, the lower mold 2 flips 180°.

[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 is in a non-stressed state, and the automobile door panel injection mold cavity can be kept vertically upward. During injection molding, the upper mold 11 is rotated to the top of the lower mold 2. Then, the upper mold 11 and the lower mold 2 are fully and tightly attached, and the injection plastic is injected into the automobile door panel injection mold cavity. After the injection plastic is completely injected, the cooling liquid is circulated in the cooling chamber 38, and then the automobile door panel injection mold cavity is quickly cooled and shaped. When the automobile door panel in the automobile door panel injection mold cavity is cooled and shaped, the liquid spraying and detection components first detect the formed door panel, and then the liquid spraying and detection components detect the formed door panel. During the test, under the driving action of the screw lifting module 42, the axial screw transmission module 24 and the longitudinal screw transmission module 26, the axis shift frame 25 moves along the specified track. After the axis shift frame 25 moves within the specified track, it drives the visual inspection probe 18, the three-dimensional scanner 19 and the ultrasonic probe 20 to perform three-dimensional scanning imaging detection, visual imaging analysis detection and ultrasonic detection on the automobile door panel along the surface of the automobile door panel. After the detection is completed, the vacuum suction seat 14 rotates to the top of the lower mold 2, and the vacuum suction nozzle 16 moves and vacuum sucks the formed door panel through vacuum suction. After the vacuum suction nozzle 16 completes vacuum suction of the door panel, Driven by the rotation of the turntable 7, the vacuum suction nozzle 16 drives the sucked door panel to move to the annular blanking belt 13. The annular blanking belt 13 transports the molded door panel on the annular blanking belt 13 to the designated production line based on the test results of the liquid spraying and the detection component. When the automobile door panel is completed in the injection mold cavity, the upper turntable 7 rotates. In the process of the vibration plate 27 approaching the lower mold 2, the missing bevel gear ring 28 is first connected to the driven bevel gear 30 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 injection molding is completed. The mold cavity is set vertically downward. After the automobile door panel injection mold cavity is set vertically downward, the limiting notch 29 is set, so that the limiting frame 6 loses its limiting effect. 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 away, thereby effectively realizing the automatic cleaning and automatic impurity removal of the automobile door panel injection mold cavity after a single injection molding, 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 automobile door panel in the automobile door panel injection mold cavity completes the unloading and flipping cleaning operations, under the driving action of the screw lifting module 42, the axial screw transmission module 24 and the longitudinal screw transmission module 26, the axis 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.
