2. An automated intelligent injection molding machine according to claim 1, characterized in that: the anti-rotation limit mechanism also includes a limit rod and a limit rail, the limit rod is fixedly mounted on the lower surface of the sliding baffle, the limit rail is fixedly mounted on the machine platform, the inner side wall of the limit rail is in sliding contact with the limit rod, and the limit rail is set as a heart-shaped track.

3. An automated intelligent injection molding machine according to claim 1, characterized in that: the anti-rotation limit mechanism also includes a reset component, the reset component includes a fixed block, a sliding reset spring and a guide slide rod, the fixed block is fixedly mounted on both ends of the sliding baffle, and both side walls of the rotating frame are fixedly mounted with connecting blocks, the two ends of the sliding reset spring are respectively fixedly connected to the fixed block and the connecting block, the guide slide rod is fixedly mounted on the fixed block, and the guide slide rod is slidably connected to the connecting block.

4. An automated intelligent injection molding machine according to claim 1, characterized in that: a lap groove is opened at one end of the bottom of the support platform, and lap blocks are fixedly installed at both ends of the rotating frame, and the lap blocks are adapted to overlap with the lap groove.

4. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole comprises a screw bolt, and a nut. The through-hole comprises a screw bolt, and a nut. The through-hole comprises a screw bolt, and a nut.

6. An automated intelligent injection molding machine according to claim 1, characterized in that: the flip assembly includes a lower turntable, an upper turntable and an elastic turnbar, the lower turntable is fixedly mounted on the side of the sliding baffle, the upper turntable is fixedly mounted on the bottom of the support platform, and the two ends of the elastic turnbar are respectively rotatably connected to the lower turntable and the upper turntable.

7. An automated intelligent injection molding machine according to claim 1, characterized in that: a guide rod and a lifting cylinder are fixedly installed on the support frame, the lifting drive frame is slidably installed on the guide rod, and the driving end of the lifting cylinder is fixedly connected to the lifting drive frame.

8. An automated intelligent injection molding machine according to claim 1, characterized in that: the injection molding equipment includes a barrel, a loading bin, a pushing mechanism and an injection head, the injection head is fixedly mounted on the output end of the barrel, the barrel, the loading bin and the pushing mechanism are all fixedly mounted on a lifting drive frame, the loading bin is used to transport materials into the barrel, and the pushing mechanism is used to stir and mix the materials and allow the materials to be ejected from the injection head.

9. An automated intelligent injection molding machine according to claim 8, characterized in that: a vertical guide rod is fixedly installed on the pressure plate, the vertical guide rod is slidably connected to the support frame, and a block is fixedly installed on the vertical guide rod, a sleeve is fixedly installed on the outer wall of the barrel, the block is slidably connected to the inner wall of the sleeve, and the diameter of the block is larger than the diameter of the bottom opening of the sleeve, and a support spring is fixedly installed between the upper end of the vertical guide rod and the inner top of the sleeve.

10. A method for injection molding a feeder card, using an automated intelligent injection molding machine according to any one of claims 1 to 9, characterized in that the specific steps are:

Put the plastic raw materials into the injection molding equipment, and start the injection molding equipment to preheat the plastic raw materials;

Operate the lifting drive frame to descend on the support frame, driving the injection molding equipment and the upper mold to move downward, closing the upper mold and the lower mold, and injecting molten plastic into the mold through the injection molding equipment;

After the injection molding is completed, the lifting drive frame is operated to move upward on the support frame to separate the upper mold and the lower mold, and then the rotating frame is controlled to rotate.
