[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1-6 As shown, a sealing rubber gasket molding die includes a mounting base 1. The left and right sides of the top of the mounting base 1 are symmetrically fixedly connected with moving mechanisms 4. The two moving mechanisms 4 at the upper end are fixedly connected to the opposite surfaces of the lower mold 2. The inner surface of the lower mold 2 is slidably connected with a demolding mechanism 5. The upper end of the lower mold 2 is engaged with an upper mold 3.

[0029] In this embodiment, the demolding mechanism 5 is installed at the lower end of the inner surface of the lower mold 2. The bidirectional threaded rod 402 is driven by the dual-drive motor box 407, so that the bidirectional threaded rod 402 is threadedly connected to the moving block 2 403 inside the support bearing 401. Through the rotation of the bidirectional threaded rod 402, the moving block 2 403 and the fixed plate 405 can move up and down with the mounting plate 501. The top of the demolding rod 502 is fixed with a push seat 504. By pushing the push seat 504 upward, the rubber pad formed inside the molding cavity 201 can be pushed out of the molding cavity 201, thereby achieving the demolding effect. The operation is simple and convenient. In order to avoid the problem of air bubbles due to incomplete casting during the mold casting process, the installed mold seat is vibrated by the vibration device 6, which can help improve product quality and ensure that the rubber pad can fill the mold cavity evenly during the molding process, reducing internal air bubbles and voids.

[0030] Specifically, refer to Figure 2 and Figure 6In this embodiment, the moving mechanism 4 includes four dual-drive motor housings 407. Connecting seats 406 are fixedly connected to the front and rear ends of each of the four dual-drive motor housings 407. Bidirectional threaded rods 402 are rotatably connected to the bottom of each of the four lower connecting seats 406. Support bearings 401 are rotatably connected to the outer surfaces of the upper and lower ends of each of the four bidirectional threaded rods 402. Support plates 404 are fixedly connected to the bottom of each of the four lower support bearings 401. Moving blocks 403 are threadedly connected to the outer surfaces of each of the four bidirectional threaded rods 402. Fixing plates 405 are fixedly connected to the opposing surfaces of two moving blocks 403 located at the same end. The opposing surfaces of two fixing plates 405 located at the same end share a common... The mounting plate 501 is fixedly connected. When demolding the mold, there is a problem that the displacement of the demolding auxiliary structure is difficult to adjust. To solve this problem, the bidirectional threaded rod 402 is driven by the dual drive motor box 407, so that the bidirectional threaded rod 402 is threadedly rotated with the moving block 403 inside the support bearing 401. By rotating the bidirectional threaded rod 402, the moving block 403 and the fixed plate 405 can move up and down with the mounting plate 501. The adjustment method is simple and convenient. Moreover, multiple demolding rods 502 can be set on the top of the mounting plate 501, and multiple mold demolding operations can be performed in the same batch, which can save time and costs to a certain extent.

[0031] Further reference Figure 4 and Figure 5 In this embodiment, demolding rods 502 are symmetrically fixedly connected to the top of the two mounting plates 501. Pushing seats 504 are fixedly connected to the top of several demolding rods 502. Molding cavities 201 are slidably connected to the upper end of the outer surface of several pushing seats 504. The lower mold mounting plate seat 202 is fixedly connected to the outer surface of several molding cavities 201. Bottom sealing rings 503 are fixedly connected to the end of the outer surface of several pushing seats 504 near the molding cavity 201. When the mold is demolded, it is easy to cause scratches, deformation or damage. Moreover, due to various reasons and conditions, the molded mold material is easy to stick to the inside of the mold and is not easy to remove. In order to optimize this phenomenon, demolding rods 502 are set. Pushing seats 504 are fixedly connected to the top of the demolding rods 502. By the upward displacement of the pushing seats 504, the rubber pads formed inside the molding cavity 201 can be pushed out of the molding cavity 201, thereby achieving the demolding effect. The operation is simple and convenient.

[0032] Further reference Figure 2 and Figure 3In this embodiment, the top of each of the four connecting seats 406 at the upper end is rotatably connected to a bidirectional threaded rod 402. The outer surfaces of the four bidirectional threaded rods 402 at the upper end are threadedly connected to a moving block 304. The opposite surfaces of the four moving blocks 304 are fixedly connected to an upper mold mounting plate 303. The front and rear ends of the inner surface of the upper mold mounting plate 303 are symmetrically fixedly connected to pressure seats 301. The top of each pressure seat 301 is fixedly connected to a top sealing ring 302. The upper mold mounting plate 303 is threadedly rotated to the bidirectional threaded rod 402 through the moving blocks 304, thereby achieving the effect of adjusting the structure of the upper mold 3 up and down. After the mold material is poured into the lower mold 2, it is filled and compacted by the upper mold 3.

[0033] Specifically, refer to Figure 1 In this embodiment, a vibration device 6 is fixedly connected to the bottom of the mounting base 1. In order to avoid the problem of air bubbles due to incomplete casting during the mold casting process, the vibration device 6 is used to vibrate the installed mold base, which can help improve product quality, ensure that the rubber pad can evenly fill the mold cavity during the molding process, reduce internal air bubbles and voids, and thus produce products with smooth surfaces and accurate dimensions.

[0034] The vibration device 6 in this solution can be a multi-dimensional vibration eccentric rotary device in the prior art. It can provide vibration for the mold mechanism to ensure that the rubber pad can fill the mold cavity evenly during the molding process, reduce internal air bubbles and voids, and thus produce a product with a smooth surface and accurate dimensions. Since it is a very mature product in the prior art, it will not be described in detail in this application.

[0035] It should be noted that the specific installation method, circuit connection method, and control method of the dual-drive motor box used in this utility model are all conventional designs, and will not be described in detail here.

[0036] The working principle of this utility model is as follows: In use, the demolding mechanism 5 is installed at the lower end of the inner surface of the lower mold 2. The bidirectional threaded rod 402 is driven by the dual drive motor box 407, so that the bidirectional threaded rod 402 is threadedly connected to the moving block 2 403 inside the support bearing 401. Through the rotation of the bidirectional threaded rod 402, the moving block 2 403 and the fixed plate 405 can move up and down with the mounting plate 501. The top of the demolding rod 502 is fixed with a push seat 504. By pushing the push seat 504 upward, the rubber pad formed inside the molding cavity 201 can be pushed out of the molding cavity 201, thereby achieving the demolding effect. The operation is simple and convenient. In order to avoid the problem of air bubbles due to incomplete casting during the mold casting process, the vibration device 6 is used to vibrate the installed mold seat, which can help improve product quality and ensure that the rubber pad can fill the mold cavity evenly during the molding process, reducing internal air bubbles and voids.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
