Description

Technical Field

[0001] This utility model relates to the field of airbag shell manufacturing technology, specifically a mold for manufacturing automotive airbag shells. Background Technology

[0002] Cars have become an indispensable means of transportation for people, bringing great convenience to their travels. Car airbags can protect the people inside the car when a collision occurs. Airbags are generally located under the airbag cover. In order to produce the cover quickly, manufacturers usually use molds.

[0003] However, after the airbag shell is injection molded, in order to ensure a more reliable deployment in an emergency when the shell is installed on a car, the shell is trimmed to reduce its thickness. However, existing manufacturers often need to set up an additional processing line to perform the trimming process, which is very costly and impractical. To address the above problems, the inventor proposes a mold for manufacturing automotive airbag shells to solve the aforementioned issues. Utility Model Content

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a mold for manufacturing an automotive airbag shell, comprising a base, a support frame fixedly installed at the top of the base, a symmetrically distributed first telescopic rod fixedly installed at one end of the support frame, an upper mold fixedly connected to one end of the first telescopic rod, an injection pipe fixedly installed at the top of the upper mold, a lower mold movably installed on the top surface of the base, a transverse groove opened in the middle of the support frame, a double-ended lead screw rotatably installed on the inner side of the transverse groove, symmetrically distributed Z-shaped plates threaded on the outer side of the double-ended lead screw, a second telescopic rod fixedly connected to one end of each Z-shaped plate, a connecting block fixedly connected to one end of each second telescopic rod, a cutting edge ring fixedly connected to one end of each connecting block, a motor fixedly installed on the outer side of the support frame, and the drive end of the motor fixedly connected to one end of the double-ended lead screw.

[0006] Preferably, a guide plate is fixedly mounted on the inner side of the transverse groove, and one end of each Z-shaped plate is slidably sleeved on the outer side of the guide plate.

[0007] Preferably, a magnetic block is fixedly connected to one end of each of the cutting rings.

[0008] Preferably, the outer side of the fixing seat is fitted with symmetrically distributed limiting rings, one end of which is in contact with the inner wall of the fixing seat.

[0009] Preferably, the lower mold has symmetrically distributed handles fixedly installed on its side end.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Through the cooperation of motor, double-headed lead screw, Z-shaped plate, guide plate, magnetic block, second telescopic rod, connecting block, and cutting ring, the cutting ring is combined and then the second telescopic rod pushes the connecting block and the cutting ring to move down. The cutting ring moves down to cut the outer wall of the shell, thereby realizing the thickness reduction and trimming of the airbag shell. This allows injection molding and trimming to be completed successively, improving production efficiency and reducing the layout of the processing line, making it more economical and practical.

[0012] 2. The rotating shaft rotates on the fixed base, which facilitates the rotation of the connecting plate. The connecting plate then drives the lower mold to move and flip, making it easier to flip and demold the airbag shell and some cutting waste material that have been injected on the connecting plate, thus improving the convenience of material handling.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: a mold for manufacturing an automotive airbag shell, including a base 1, a support frame 11 fixedly installed at the top of the base 1, a symmetrically distributed first telescopic rod 12 fixedly installed at one end of the support frame 11, an upper mold 13 fixedly connected to one end of the first telescopic rod 12, an injection pipe 14 fixedly installed at the top of the upper mold 13, a lower mold 15 movably installed on the top surface of the base 1, a transverse groove 16 opened in the middle of the support frame 11, a double-ended lead screw 17 rotatably installed on the inner side of the transverse groove 16, a symmetrically distributed Z-shaped plate 18 threaded on the outer side of the double-ended lead screw 17, a second telescopic rod 19 fixedly connected to one end of each Z-shaped plate 18, a connecting block 20 fixedly connected to one end of each second telescopic rod 19, a cutting edge ring 21 fixedly connected to one end of each connecting block 20, and a motor 22 fixedly installed on the outer side of the support frame 11, the drive end of the motor 22 being fixedly connected to one end of the double-ended lead screw 17.

[0020] A fixed base 23 is fixedly installed at the top of the base 1. A rotating shaft 24 is rotatably installed on the inner side of the fixed base 23. A connecting plate 25 is fixedly connected to the outer side of the rotating shaft 24. One end of the connecting plate 25 is fixedly connected to the lower mold 15. A symmetrically distributed positioning block 26 is fixedly installed on one side of the top surface of the base 1. The inner side of the positioning block 26 is movably fitted with the outer side of the lower mold 15.

[0021] By adopting the above technical solution, the rotating shaft 24 rotates on the fixed seat 23, which facilitates the rotating shaft 24 to drive the connecting plate 25 to rotate. The connecting plate 25 then drives the lower mold 15 to move and flip, which makes it easier to flip and demold the airbag shell and some cutting waste on the connecting plate 25, thus improving the convenience of material handling.

[0022] A guide plate 27 is fixedly mounted on the inner side of the transverse groove 16, and one end of the Z-shaped plate 18 is slidably sleeved on the outer side of the guide plate 27.

[0023] By adopting the above technical solution, the Z-shaped plate 18 is slid on the guide plate 27 to guide and limit itself.

[0024] A magnetic block 28 is fixedly connected to one end of each edge-cutting ring 21.

[0025] By adopting the above technical solution, the magnetic block 28 is set to make the merging of the cutting ring 21 more stable.

[0026] The outer side of the fixed base 23 is fixedly fitted with symmetrically distributed limiting rings 29, one end of which is in contact with the inner wall of the fixed base 23.

[0027] By adopting the above technical solution, the rotating shaft 24 is limited by setting a limit ring 29 to make it more stable.

[0028] The lower mold 15 has symmetrically distributed handles 30 fixedly installed on its side.

[0029] By adopting the above technical solution, the handle 30 is set to facilitate manual gripping of the handle 30 to rotate the lower mold 15.

[0030] Working principle: First, the first telescopic rod 12 is activated to push the upper mold 13 down to connect with the lower mold 15 for injection molding. The injection material is added from the injection pipe 14. After injection molding is completed, the first telescopic rod 12 is controlled to pull the upper mold 13 back to its original position. Then, the motor 22 is activated to control the double-headed screw 17 to rotate. The rotation of the double-headed screw 17 drives the Z-shaped plates 18 to move relative to each other. The guide plate 27 guides the Z-shaped plates 18. The Z-shaped plates 18 then drive the second telescopic rod 19 and the connecting block 20 to move relative to each other. The connecting block 20 drives the trimming rings 21 to move relative to each other until they merge. After the trimming rings 21 merge, The second telescopic rod 19 is used to push the connecting block 20 and the trimming ring 21 downwards. The trimming ring 21 moves downwards to trim the outer wall of the shell, thereby reducing the thickness of the airbag shell and trimming it. This allows the injection molding and trimming to be completed successively, improving production efficiency and reducing the need for processing line laying, making it more economical and practical. The rotating shaft 24 rotates on the fixed seat 23, which facilitates the rotation of the connecting plate 25. The connecting plate 25 then drives the lower mold 15 to move and flip, making it easier to flip and demold the airbag shell that has been injected on the connecting plate 25 and some of the trimming waste, thus improving the convenience of material handling.
