The diameter of the stepped groove 13 ranges from large to small. A T-shaped mold core 10 is slidably connected in the stepped groove 13. A columnar protrusion is provided on the side of the T-shaped mold core 10 facing the stepped groove 13. The columnar protrusion is adapted to the small mouth of the stepped groove 13. Both sides of the T-shaped mold core 10 are adapted to the large diameter of the stepped groove 13. The vertical end of the T-shaped mold core 10 is slidably sleeved with the mounting shaft 11. The horizontal ends of the T-shaped mold core 10 are slidably sleeved with vehicle mold parts on the outer sides. The vertical end of the T-shaped mold core 10 is inserted into the top mold 1, and the bottom surface of the top mold 1 is tightly attached to the vehicle cover part 4. An annular mounting groove 9 is provided on the side of the top mold 1 facing the T-shaped mold core 10. The inner diameter of the annular mounting groove 9 is T-shaped as a whole. A protective component for wrapping the mounting shaft 11 is provided in the annular mounting groove 9. , both sides of the lower end of the top mold 1 are provided with fixing components for fixing the protective components, and a placement groove 16 is provided inside the bottom mold 2. A reset component for resetting the T-type mold core 10 after being pressed down is provided in the placement groove 16. Both sides of the lower end of the bottom mold 2 are provided with locking parts for locking the reset component. By sleeveing ​​the installation shaft 11 on the vertical end cover of the T-type mold core 10, and at the same time, the bottom protrusion of the T-type mold core 10 is connected to the reset component, and the top mold 1 is sleeved on the T-type mold core 10, and the protective component is sleeved on the outside of the installation shaft 11 to protect the installation shaft 11 and prevent the installation shaft 11 from contacting the outside, thereby improving the accuracy of the side wall of the installation shaft 11 after installation. At the same time, the T-type mold core 10 moves downward with the pressure of the top mold 1, so that the installation shaft 11 and the T-type mold core 10 are synchronously lowered to press the reset component, so that the installation shaft 11 is accurately and intactly installed in the vehicle cover part 4.

[0022] Reference Figure 2-Figure 3The protection assembly includes a protection ring 5 and a first spring 7. The protection ring 5 is slidably arranged in the annular mounting groove 9. The end of the protection ring 5 extending into the annular mounting groove 9 is T-shaped and hung on the inner bottom wall of the annular mounting groove 9. The first spring 7 is fixedly connected between the top surface of the protection ring 5 and the inner top wall of the annular mounting groove 9. The inner side wall of the protection ring 5 is in contact with the outer side wall of the mounting shaft 11. The mounting shaft 11 is wrapped by the protection ring 5 to enhance the protection of the outer wall of the mounting shaft 11. If the top mold 1 is pressed down, the protection ring 5 will compress the first spring 7 and retract the protection ring 5 into the annular mounting groove 9.

[0023] Reference Figure 3 The fixing assembly includes an L-shaped plug rod 6 and a second spring 14. A slot communicating with the annular mounting groove 9 is opened at the lower end of the top mold 1. The horizontal end of the L-shaped plug rod 6 is slidably connected in the slot, and the vertical end of the L-shaped plug rod 6 is located on the outside of the top mold 1. The side wall of the protective ring 5 is provided with a socket 8 compatible with the L-shaped plug rod 6. A second spring 14 is provided between the horizontal end of the L-shaped plug rod 6 and the slot. As the protective ring 5 is received in the annular mounting groove 9, when the socket 8 of the annular protective ring 5 is coaxial with the socket 8 of the bottom mold 2, the horizontal end of the L-shaped plug rod 6 is pushed into the socket 8 by the second spring 14 to fix the protective ring 5. When it is used again, the vertical end of the T-shaped mold core 10 is first contacted with the top surface, and then the L-shaped plug rod 6 is pulled outward to lower the protective ring 5 again and cover the mounting shaft 11.

[0024] Reference Figure 3 The top surface of the horizontal end of the L-shaped rod 6 abuts against the outer side surface of the protective ring 5. Due to the second spring 14, the horizontal end of the L-shaped rod 6 always abuts against the side wall of the protective ring 5.

[0025] Reference Figure 2-Figure 4 The reset component includes a third spring 18. The protrusion on the bottom surface of the T-shaped mold core 10 is fixedly connected to the connecting rod 12. The lower end of the connecting rod 12 slides and extends into the placement groove 16. The upper end of the connecting rod 12 is in the step groove 13 and the lower end is in the placement groove 16. The bottom end of the connecting rod 12 is fixedly connected to a pressing plate 15 that slides in the placement groove 16. The third spring 18 is fixedly connected between the bottom surface of the pressing plate 15 and the inner bottom wall of the placement groove 16. The T-shaped mold core 10 descends and compresses the third spring 18. When the mounting shaft 11 is installed into the vehicle cover part 4, the composite component resets the T-shaped mold core 10 to facilitate the next use.

[0026] Reference Figure 2-Figure 4The locking part includes a threaded rod 3, the threaded rod 3 threads through the bottom mold 2, and communicates with the placement groove 16. Both sides of the pressure plate 15 are provided with threaded holes 17 adapted to the threaded rod 3. The pressure plate 15 descends as the T-type mold core 10 descends, and then the pressure plate 15 descends along the placement groove 16. When the installation shaft 11 is installed into the vehicle cover part 4, the threaded hole 17 is coaxial with the threaded rod 3. The threaded rod 3 is twisted to lock the pressure plate 15. After the vehicle cover part 4 is taken out, the threaded rod 3 is loosened to reset the T-type mold core 10.

[0027] Working principle:

[0028] First, put the vehicle cover part 4 on the bottom of the T-type mold core 10, and then put the installation shaft 11 on the vertical end of the T-type mold core 10, and the bottom wall of the installation shaft 11 is tightly attached to the bottom top surface of the T-type mold core 10, and then put the top mold 1 along the vertical end of the T-type mold core 10, cover the top surface of the installation shaft 11 and make it close to the top surface of the installation shaft 11, and then pull the L-shaped plug rods 6 on both sides of the top mold 1 outward to make the protective ring 5 cover the installation shaft 11, and then use the hydraulic press to press the top mold 1 to move the top mold 1 downward, and at the same time, the T-type mold core 10 and the installation shaft 11 descend synchronously, and the protective ring 5 is received in the annular installation groove 9, and the T-type mold core 10 presses the pressure plate 15 to make the third spring 18 expand and contract, and when the installation shaft 11 is completely pressed into the vehicle cover part 4, stop the hydraulic press, and fix the protective ring 5 and the pressure plate 15 with the threaded rod 3 and the L-shaped plug rod 6 to facilitate the removal of the vehicle cover part 4 after installation.
