A first spring 505 is fixedly connected between the support plate 504 and the bottom inner wall of the fixed frame 501. The first spring 505 is sleeved on the outer surface of the movable rod 503. A connecting shaft is rotatably connected to the rear outer surface of the fixed frame 501, and a limiting gear 506 is fixedly sleeved on the outer surface of the connecting shaft. Specifically, the tooth plate 502 is inserted into the fixed frame 501. When the tooth plate 502 engages with the limiting gear 506, the limiting gear 506 rotates. As the tooth plate 502 is inserted, the tooth plate 502 squeezes the support plate 504 to compress the first spring 505.

[0022] A pull rod 507 is movably inserted into the front outer surface of the fixed frame 501, and a limit block 508 is fixedly sleeved on one end of the pull rod 507 located inside the fixed frame 501. A second spring 509 is fixedly connected between the limit block 508 and the front inner wall of the fixed frame 501. A limit strip 511 is fixedly connected to the top outer surface of the support plate 504, and a limit groove 510 adapted to the limit strip 511 is provided on the bottom outer surface of the limit block 508.

As the toothed plate 502 is inserted, the toothed plate 502 drives the limiting gear 506 to rotate. When the toothed plate 502 contacts with the supporting plate 504, as the toothed plate 502 is inserted, the first spring 505 is compressed, and the supporting plate 504 drives the limiting strip 511 downward, so that one end of the limiting strip 511 moves out of the limiting groove 510. , so that under the action of the second spring 509, one end of the pull rod 507 is inserted into two adjacent teeth of the limit gear 506 to limit the limit gear 506. At this time, when the tooth plate 502 needs to move vertically, it needs to drive the limit gear 506 to rotate, and the limit gear 506 is blocked so that the tooth plate 502 cannot move, so that the lower mold 2 is installed on the threaded plate 4, and the upper mold 3 and the lower mold 2 are assembled in the same way. When disassembly is required, the pull rod 507 is pulled to make one end of the pull rod 507 disengaged from the teeth of the limit gear 506, so that the upper mold 3 and the lower mold 2 can be quickly assembled without using bolts, thereby improving the assembly efficiency and indirectly improving the injection molding efficiency.

Specifically, when the half gear 702 drives the rack 703 to move, it drives the convex plate to slide on the surface of the sliding rod and compresses the fifth spring 708. When the half gear 702 is out of mesh with the rack 703, the rack 703 is reset under the elastic force of the fifth spring 708.

[0033] In this embodiment, the telescopic column 704 includes a fixed column and a movable column. The outer surfaces of the fixed column and the movable column are provided with screw holes.

With the insertion of the toothed plate 502, the toothed plate 502 drives the limiting gear 506 to rotate. When the toothed plate 502 contacts the support plate 504, with the insertion of the toothed plate 502, the first spring 505 is compressed, and the support plate 504 drives the limiting strip 511 downward, so that one end of the limiting strip 511 moves from the limiting groove 5 10 is disengaged from the inside, so that under the action of the second spring 509, one end of the pull rod 507 is inserted into two adjacent teeth of the limit gear 506 to limit the limit gear 506. At this time, when the tooth plate 502 needs to move vertically, it needs to drive the limit gear 506 to rotate, and the limit gear 506 is blocked so that the tooth plate 502 cannot move, so that the lower mold 2 is installed on the threaded plate 4, and the upper mold 3 and the lower mold 2 are assembled in the same way. When disassembly is required, the pull rod 507 is pulled to make one end of the pull rod 507 disengaged from the teeth of the limit gear 506, so that the upper mold 3 and the lower mold 2 can be quickly assembled without using bolts, thereby improving the assembly efficiency and indirectly improving the injection molding efficiency.

[0036] When the upper mold 3 and the lower mold 2 are assembled, injection molding is carried out inside the mold, and the injection molding material is injection molded inside the molding cavity tube 201, and then the pedal 604 is stepped on, and the pedal 604 drives the hook rod 602 to rotate on the support shaft 603, and the pedal 604 drives the hook rod 602 to push the top plate 601 upward, and the top plate 601 drives the bottom plate 204, so that the piston rod 202 drives the piston plate 203 to move upward, and the molded charging port cover is pushed out. When the force on the pedal 604 is stopped, the top plate 601 and the bottom plate 204 are respectively driven to reset by the third spring 607 and the sixth spring.

[0037] During injection molding, the motor 701 is turned on, and the motor 701 drives the half gear 702 to rotate. When the half gear 702 is engaged with the rack 703, the rack 703 is driven to move as the half gear 702 rotates, and the rack 703 drives the telescopic column 704 to move the knocking head 706. When the knocking head 706 contacts the lower mold 2, when the motor 701 drives the half gear 702 to disengage from the rack 703, the rack 703 is reset under the elastic force of the fifth spring 708, so that as the motor 701 works, the knocking head 706 is driven to knock and vibrate the surface of the lower mold 2, so as to discharge the bubbles in the molding cavity 201 and improve the quality of the finished product of the automobile charging port cover.
