[0022] Example
[0023] Please see Figures 1-5 In this embodiment of the present invention, an automotive airbag bracket mold includes a mounting frame 1. Several electric push rods 3 are evenly arranged on the upper inner wall of the mounting frame 1. An upper shell 4 is provided at the end of the telescopic arm of the bottom of the electric push rod 3. A hydraulic rod 5 is provided on the upper shell 4. An mounting plate 6 is provided at the end of the telescopic arm of the bottom of the hydraulic rod 5. A punch 7 is provided on the mounting plate 6. A lower shell 2 is provided on the lower inner wall of the mounting frame 1. A concave mold 11 is provided inside the lower shell 2. When bracket fabrication is required, the worker places the raw material on the concave mold 11. Then, the electric push rods 3 drive the upper shell 4 downwards. When the upper shell 4 contacts the lower shell 2, the hydraulic rods 5 drive the punch 7 downwards, thereby completing the bracket fabrication. After fabrication, the electric push rods 3 drive the upper shell 4 to move, allowing the bracket to be removed from the concave mold 11, thus completing the bracket fabrication.
[0024] The punch 7 is evenly provided with several limiting blocks, and the mounting plate 6 is evenly provided with several cavities. A first telescopic rod 8 is provided in each cavity, and a limiting post 9 is provided at the end of the telescopic arm of the first telescopic rod 8. The limiting block is provided with a limiting groove that cooperates with the limiting post 9. Under the action of the limiting post 9 and the limiting groove, the installation quality of the punch 7 is ensured, and the punch 7 is also easy to disassemble, which facilitates the replacement of the punch 7 by the staff to meet the actual production needs. A first spring 10 is sleeved on the outside of the first telescopic rod 8. One end of the first spring 10 is connected to the inner wall of the cavity, and the other end of the first spring 10 is connected to the limiting post 9. Under the action of the first spring 10, the connection quality between the limiting post 9 and the limiting groove is ensured, which in turn ensures the installation quality of the punch 7.
[0025] The lower shell 2 is also evenly provided with several mounting cavities. A slider 12 is slidably arranged in the mounting cavity. A locking block 16 is provided on the side wall of the slider 12. The die 11 is provided with a locking groove that cooperates with the locking block 16. Under the action of the locking block 16 and the locking groove, the installation quality of the die 11 is guaranteed, and the die 11 is also convenient to be disassembled. This allows the die 11 to be replaced synchronously with the punch 7, thereby ensuring the efficiency of the mold. A support rod 13 is provided on the slider 12. The support rod 13 passes through the lower shell 2 and is slidably connected to the lower shell 2. The locking block 16 can be moved by the support rod 13. A second spring 15 is sleeved on the outside of the support rod 13. One end of the second spring 15 is connected to the inner wall of the mounting cavity, and the other end of the second spring 15 is connected to the slider 12. Under the action of the second spring 15, the connection quality between the locking block 16 and the locking groove is guaranteed, thereby ensuring the installation quality of the die 11. A handle 14 is provided at the outer end of the support rod 13. The support rod 13 can be moved by the handle 14.
[0026] The cavity 11 is also provided with a slot, in which a second telescopic rod 17 is provided. The end of the telescopic arm of the second telescopic rod 17 is provided with a limit rod 18. The locking block 16 is provided with a limit groove that works in conjunction with the limit rod 18. At this time, under the action of the limit rod 18 and the limit groove, the connection quality between the locking block 16 and the slot is ensured. A third spring 19 is sleeved on the outside of the second telescopic rod 17. One end of the third spring 19 is connected to the limit rod 18, and the other end of the third spring 19 is connected to the inner wall of the slot. At this time, under the action of the third spring 19, the connection quality between the limit rod 18 and the limit groove is ensured.
[0027] In actual use, the worker places the raw material on the die 11. Then, the electric push rod 3 is activated, driving the upper shell 4 and its internal hydraulic rod 5, mounting plate 6, and punch 7 to move downwards as a whole until the upper shell 4 is in close contact with the lower shell 2. At this time, the hydraulic rod 5 works further, pushing the punch 7 on the mounting plate 6 downwards to cooperate with the raw material in the die 11 to complete the pressing and forming of the bracket. During the installation of the punch 7, the limiting block and the limiting post 9 cooperate closely to ensure that the punch 7 is stably installed and easy to disassemble and replace. At the same time, the die 11 also ensures its stability during operation through the locking mechanism of the locking block 16 and the locking groove. After the bracket is made, the electric push rod 3 drives the upper shell 4 to rise, releasing the bracket in the die 11.
