Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please see Figures 1 to 4 In one aspect, this utility model provides a molding die for a vehicle wheel hub dust cover, including a worktable 1, a molding die body 2, and a demolding mechanism. The demolding mechanism includes a motor 3, a worm gear 4, a worm wheel 5, a transmission assembly, a lifting rod 6, a lifting head 7, and a pushing assembly.

[0028] The molding die body 2 is mounted on the worktable 1. The motor 3 is fixedly connected to the worktable 1 and located on the worktable 1. The worm gear 4 is fixedly connected to the output end of the motor 3 and rotatably connected to the worktable 1. The worm wheel 5 is engaged with the worm gear 4 and rotatably connected to the worktable 1. The transmission assembly is mounted between the worm gear 4 and the worktable 1. The lifting rod 6 is mounted on the transmission assembly. The lifting head 7 is fixedly connected to the lifting rod 6 and located on the side of the lifting rod 6 away from the transmission assembly. The pushing assembly is mounted on the worktable 1.

[0029] In this embodiment, the workbench 1 provides the installation conditions for the molding die body 2. The molding die body 2 can be used to process the wheel hub dust cover. When it is necessary to demold the processed wheel hub dust cover, the motor 3 is started. The motor 3 drives the worm gear 4 to rotate. The worm gear 4 drives the worm wheel 5 to rotate. The worm wheel 5 drives the transmission assembly to move. The transmission assembly drives the lifting rod 6 to move away from the workbench 1. The lifting rod 6 drives the lifting head 7 to move the wheel hub dust cover on the molding die body 2 away from the molding die body 2 until the wheel hub dust cover is separated from the molding die body 2. Then, the pushing assembly works to push the wheel hub dust cover away from the molding die body 2, thus completing the separation of the wheel hub dust cover. This solves the problem that the wheel hub cover needs to be manually removed from the mold after production.

[0030] Furthermore, the transmission assembly includes a bidirectional screw 8, two sleeves 9, two transmission rods 10, and a moving plate 11. The bidirectional screw 8 is fixedly connected to the worm gear 5 and rotatably connected to the worktable 1, and is located between the worktable 1 and the worm gear 5. The two sleeves 9 are threadedly connected to the bidirectional screw 8 and are located around the bidirectional screw 8. The two transmission rods 10 are rotatably connected to the two sleeves 9 and are located on the two sleeves 9. The moving plate 11 is rotatably connected to the two transmission rods 10 and fixedly connected to the lifting rod 6.

[0031] In this embodiment, the rotation of the bidirectional screw 8 can cause the two sleeves 9 to move closer to or further away from each other. The movement of the two sleeves 9 can cause the two transmission rods 10 to rotate. When the angle between the two transmission rods 10 and the sleeves 9 increases, the two transmission rods 10 cause the moving plate 11 to move away from the worktable 1, and then the moving plate 11 causes the lifting rod 6 to move away from the worktable 1. When the angle between the two transmission rods 10 and the sleeves 9 decreases, the two transmission rods 10 cause the moving plate 11 to move closer to the worktable 1, and then the moving plate 11 causes the lifting rod 6 to move closer to the worktable 1.

[0032] Furthermore, the transmission assembly also includes a slide rail 12 and two sliders 13. The slide rail 12 is fixedly connected to the worktable 1 and located inside the worktable 1. The two sliders 13 are slidably connected to the slide rail 12 and fixedly connected to the two sleeves 9, respectively, and are all located between the sleeves 9 and the slide rail 12.

[0033] In this embodiment, the slide rail 12 provides installation conditions for the two sliders 13. The two sliders 13 can guide and limit the two sleeves 9, thereby improving the stability of the two sleeves 9 when they move.

[0034] Furthermore, the pushing assembly includes an electric push rod 14, a pushing plate 15, two guide rods 16, and two limiting blocks 17. The electric push rod 14 is fixedly connected to the worktable 1 and is located on the worktable 1. The pushing plate 15 is fixedly connected to the output end of the electric push rod 14. The two guide rods 16 are respectively fixedly connected to the pushing plate 15 and slidably connected to the worktable 1, both penetrating the worktable 1. The two limiting blocks 17 are respectively fixedly connected to the two guide rods 16 and are located on the side of the guide rods 16 away from the pushing plate 15.

[0035] In this embodiment, the electric push rod 14 can drive the push plate 15 to move. The push plate 15 can push the wheel dust cover lifted by the lifting head 7 to the side away from the molding die body 2 to complete demolding. When the push plate 15 moves, it drives the two guide rods 16 to slide on the worktable 1. The two guide rods 16 guide the push plate 15. The two limit blocks 17 can limit the two guide rods 16 to prevent them from moving out of the preset range.

[0036] Furthermore, the demolding mechanism also includes a guide frame 18 and a recycling bin 19. The guide frame 18 is fixedly connected to the workbench 1 and is located on one side of the workbench 1. The recycling bin 19 is located below the guide frame 18.

[0037] In this embodiment, the wheel hub dust cover pushed down by the pusher plate 15 can be guided into the recycling box 19 through the guide frame 18, and the processed wheel hub dust cover can be collected through the recycling box 19.

[0038] The motor 3 is started, driving the worm gear 4 to rotate. The worm gear 4 drives the worm wheel 5 to rotate, which in turn drives the double-headed screw 8 to rotate. The double-headed screw 8 drives the two sleeves 9 to move closer together, which in turn drives the two transmission rods 10 to rotate. The two transmission rods 10 drive the moving plate 11 to move away from the worktable 1, which in turn drives the lifting rod 6 to move away from the worktable 1. The lifting rod 6 drives the lifting head 7 to move the hub anti-reflector on the forming mold body 2. The dust cover moves away from the molding die body 2 until it separates from the molding die body 2. Then, the electric push rod 14 drives the pusher plate 15 to move away from the electric push rod 14. The pusher plate 15 pushes the dust cover away from the molding die body 2. The dust cover is then guided into the recycling box 19 by the guide frame 18 for collection. This completes the separation of the dust cover and solves the problem of manually removing the pressed dust cover from the die after the production of the dust cover mold.
