Abstract
Description
Technical Field
[0001] This utility model relates to an airbag vulcanization device, belonging to the field of airbag production technology. Background Technology
[0002] The process of airbag vulcanization involves winding airbag fabric around the outer side of a cylindrical inner mold to form a cylinder. An axially extending opening is left on the side of the cylinder. The airbag fabric and inner mold are placed on a pressing and heating device, and then an end cap is placed on the end of the cylinder. The pressing and heating device presses the end cap and cylinder together from the outside, causing them to bond together through heat vulcanization. The pressed cylinder and inner mold are then removed from the pressing and heating device, the opening is opened, and the cylindrical inner mold is removed. Finally, the opening of the cylinder is sealed. Existing airbag vulcanization equipment uses a cylindrical inner mold for vulcanization. However, the length and diameter of the cylindrical inner mold are fixed, limiting its application to airbags of a single size. This results in poor flexibility and versatility, presenting certain drawbacks in its use.
[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] Please see Figures 1-5As shown, an airbag vulcanizing device includes a mounting base 1. A limiting groove is formed on the top of the mounting base 1, and a side-push width adjustment 2 is installed in the limiting groove. A first vertical connecting column 3 and a second vertical connecting column 4 are installed on the side-push width adjustment 2 assembly. Both the first vertical connecting column 3 and the second vertical connecting column 4 are fixedly connected to the side-push width adjustment 2 assembly via positioning pin assemblies 5. Support plates 6 are fixedly installed on the tops of both the first vertical connecting column 3 and the second vertical connecting column 4. A first cylindrical inner mold 7 and a second cylindrical inner mold 8 are respectively fixedly installed on the support plates 6 on both sides. L-shaped mounting brackets 9 are fixedly installed on the side walls of both vertical connecting column 3 and the second vertical connecting column 4. Telescopic push rods 10 are fixedly installed on the top of the L-shaped mounting brackets 9. First hot-press end caps 11 and second hot-press end caps 12 are fixedly installed on the telescopic ends of the telescopic push rods 10 on both sides, respectively. The first hot-press end caps 11 and the second hot-press end caps 12 are horizontally aligned with the first cylindrical inner mold 7 and the second cylindrical inner mold 8, respectively. The distance between the first vertical connecting column 3 and the second vertical connecting column 4 is adjusted using the side-push width adjustment component 2 via the limiting sliding groove on the mounting base 1 to accommodate the vulcanization requirements of airbags of different lengths. Next, the airbag fabric to be vulcanized is placed in the first cylindrical inner mold 7 and the second cylindrical inner mold 8. Then, the telescopic push rod 10 on the L-shaped mounting bracket 9 is operated to make the first hot-press end cap 11 and the second hot-press end cap 12 tightly fit into the openings of the first cylindrical inner mold 7 and the second cylindrical inner mold 8, respectively, for hot-press vulcanization. After vulcanization, the hot-press end cap is removed by the telescopic push rod 10, the vulcanized airbag is taken out, and the airbag is sealed to obtain the finished airbag. The positioning pin assembly 5 facilitates the replacement of the first cylindrical inner mold 7, the second cylindrical inner mold 8, the first hot-press end cap 11, and the second hot-press end cap 12 to adapt to the vulcanization of airbags of different diameters, thus improving the flexibility of use.
[0022] like Figure 2As shown, the side-push width adjustment 2 includes a servo motor 201 and a bidirectional threaded rod 202. The servo motor 201 is fixed to the inner wall of one end of the limiting slide groove. The bidirectional threaded rod 202 is rotatably mounted on the inner wall of the other end of the limiting slide groove via a rotating joint 203. One end of the bidirectional threaded rod 202 is fixedly connected to the output shaft of the servo motor 201. Two threaded sliders 204 are mounted on the bidirectional threaded rod 202 and are slidably engaged in the limiting slide groove. The two threaded sliders 204 are located at opposite threaded ends of the bidirectional threaded rod 202. The servo motor 201 is activated to drive the bidirectional threaded rod 202 to rotate within the limiting slide groove. Because the bidirectional threaded rod 202 has opposite threaded ends, it drives the two threaded sliders 204 to slide in opposite directions within the limiting slide groove. These two threaded sliders 204 are respectively connected to the first vertical connecting post 3 and the second vertical connecting post 4, thereby achieving distance adjustment between them. As needed, the distance between the first vertical connecting post 3 and the second vertical connecting post 4 can be precisely adjusted by controlling the forward and reverse rotation of the servo motor 201 to adapt to the vulcanization molding requirements of airbags of different sizes.
[0023] like Figure 4 and Figure 5 As shown, the positioning pin assembly 5 includes a square sleeve 501, which is fixed to the threaded slider 204. The first vertical connecting post 3 and the second vertical connecting post 4 are respectively inserted into the square sleeves 501 on both sides. A U-shaped mounting base 502 is fixedly installed on the side wall of the square sleeve 501. A positioning pin 503 is slidably installed on the U-shaped mounting base 502. One end of the positioning pin 503 is inserted into the positioning pin hole corresponding to the first vertical connecting post 3 and the second vertical connecting post 4 in the square sleeve 501. A lifting post 504 is fixedly installed at the other end of the positioning pin 503. An annular pad 505 is fixedly sleeved on the positioning pin 503. The annular pad 505 is elastically connected to the inner wall of the U-shaped mounting base 502 through a clamping spring 506. The first vertical connecting post 3 and the second vertical connecting post 4 are respectively inserted into the corresponding square inserts 501. Then, by sliding the positioning pin 503 on the U-shaped mounting base 502, one end of it is inserted into the corresponding positioning pin hole on the square insert 501 and the connecting post, achieving a stable connection. The other end of the positioning pin 503 is provided with a lifting post 504 for easy operation. The annular pad 505 is sleeved on the positioning pin 503 and connected to the inner wall of the U-shaped mounting base 502 through a clamping spring 506, ensuring that the positioning pin 503 remains stable when not subjected to external force. When adjustment or disassembly is required, simply pull the lifting column 504 upward to overcome the spring force and pull the positioning pin 503 out of the positioning pin hole. This facilitates flexible assembly and disassembly of the first vertical connecting column 3 and the second vertical connecting column 4, improving the ease of replacement of the first cylindrical inner mold 7, the second cylindrical inner mold 8, the first hot-pressed end cap 11, and the second hot-pressed end cap 12, and meeting the vulcanization molding requirements of airbags of different diameters.
