[0002] A foam mold is a mold used to produce foam parts manufactured according to the design of the foam part and the requirements of the foam production process. During the seat sponge foaming process, raw materials are injected into the mold, and then the mold is closed and heated to make the material foam and form. During the foaming and forming process, a large amount of gas is generated in the mold, which causes the pressure in the mold to increase. Some existing foam molds usually have the characteristics of being convenient for workers to open or close the mold and simple and convenient operation, but they have the characteristics of low safety and inconvenient adjustment of the fixed height.

[0003] In view of the above problems, an exhaust structure of an automobile seat foam mold disclosed in the Chinese patent with the publication number CN215320148U has the following technical key points: including an air duct, and a support plate is slidably connected to the outer surface of the support column. Through the setting of the cross support rod, the exhaust structure of the automobile seat foam mold has the effect of preventing the support plate from moving too far. Through the cooperation of the air duct, the support column and the air duct, the support plate can be opened during use, thereby preventing the danger caused by the too rapid discharge of high-pressure gas, achieving the purpose of high safety.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] As Figures 1-3 shown, the present invention provides a technical solution: an exhaust device for an automotive seat foaming mold, including an upper die holder 1, an air outlet hole 2 is opened on the upper die holder 1, an air outlet pipe 3 is fixedly installed in the air outlet hole 2, the top end of the air outlet pipe 3 extends above the upper die holder 1, a connecting pipe 4 is threadedly installed at the top end of the air outlet pipe 3, the exhaust device can be installed and disassembled by loosening and tightening the connecting pipe 4, a sleeve 5 is slidably installed on the connecting pipe 4, a groove 6 is opened at the top of the sleeve 5, two symmetrically distributed tensile springs 7 are fixedly installed on the bottom inner wall of the groove 6, and the two tensile springs 7 are used to pull the sealing rubber ring 11 below the cover plate 8 into close contact with the top of the sleeve 5. It should be noted that a channel is opened on the bottom inner wall of the groove 6 between the two tensile springs 7, and this channel is used to release hot air. The top ends of the two tensile springs 7 are fixedly installed with the same cover plate 8, a vertical pipe 9 and two springs 10 are fixedly installed at the top of the connecting pipe 4, the bottom end of the vertical pipe 9 extends into the connecting pipe 4, the two springs 10 are respectively located on the left and right sides of the vertical pipe 9, and the top ends of the two springs 10 are both fixedly connected to the sleeve 5. The two springs 9 are used to push the sleeve 5 upward to return to the initial state.

[0020] Through the above settings, it is possible to conveniently and flexibly control the descending time and amplitude of the sleeve 5 according to the actual situation, making the exhaust process more flexible and controllable, and improving the production quality of automotive seat foam molds.

[0021] In this embodiment, a protective tube 12 is fixedly installed at the top of the above-mentioned sleeve 5. The protective tube 12 is used to make the ejected hot air gush upward to avoid scalding the operator. A rubber sleeve 15 is fixedly installed on the sleeve 5. The rubber sleeve 15 is used for heat insulation and increasing friction. A sealing rubber ring 11 is fixedly installed on the top of the cover plate 8. The bottom of the sealing rubber ring 11 is in close contact with the top of the sleeve 5. By using the sealing rubber ring 11, the airtightness inside after mold closing can be improved, heat loss can be reduced, and the stability of the production of the automotive seat foam mold can be maintained.

[0022] In this embodiment, two symmetrically distributed limiting grooves 13 are formed on the outer circumferential wall of the above-mentioned connecting pipe 4. Two symmetrically distributed limiting blocks 14 are fixedly installed on the inner circumferential wall of the sleeve 5. The two limiting blocks 14 are respectively slidably installed in the corresponding limiting grooves 13. By using the combined action of the two limiting grooves 13 and the two limiting blocks 14, the moving direction and moving range of the sleeve 5 can be restricted. Handles 16 are fixedly installed on both the left and right sides of the connecting pipe 4.

[0023] With the above structure, an exhaust device for an automotive seat foaming mold provided by the present utility model can facilitate the installation and disassembly of the exhaust device, and then regularly overhaul the exhaust device and the air outlet 2 to avoid foam blocking the air outlet 2. It can also flexibly control the exhaust time according to the actual situation. And through the sealing rubber ring 11, the airtightness inside after mold closing can be effectively maintained, heat loss can be reduced, and the stability of the production of the automotive seat foam mold can be maintained. During specific use, the connecting pipe 4 of the exhaust device is threadedly installed on the air outlet pipe 3, and operations such as foam injection and mold closing are started. When the foam is heated, the hot air generated by the foam gradually accumulates. When the air pressure of the hot air inside is relatively large, the sleeve 5 is controlled to move downward. The sleeve 5 compresses the two springs 10. At the same time, the top end of the vertical pipe 9 approaches and extends into the groove 6. When the top end of the vertical pipe 9 contacts and pushes the cover plate 8 to move upward, the two tension springs 7 are in a stretched state at this time, and the hot air inside gushes out to the outside through the gap. Due to the blockage of the protective tube 12, the hot air rises along the protective tube 12 to avoid scalding the operator. When the ejected hot air is relatively small, the sleeve 5 is released. Under the action of the two springs 10, the sleeve 5 moves upward to return to the initial position. The top end of the vertical pipe 9 is separated from the cover plate 8. At the same time, the two tension springs 7 control the cover plate 8 to rebound and return to the initial position. Under the action of the sealing rubber ring 11, the channel gap is re-closed to maintain the airtightness inside, greatly improving the production quality of the automotive seat foam model. When it is necessary to overhaul the exhaust device and the air outlet 2, the connecting pipe 4 can be loosened by the two handles 16 for overhaul, greatly improving the work efficiency.

[0024] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope recorded in the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
