Description

Technical Field

[0001] This utility model relates to the field of rubber product molding technology, specifically a rubber product molding mechanism. Background Technology

[0002] Rubber product molding is a key manufacturing process that transforms uncured rubber into durable, multi-functional parts suitable for various applications. This technology is crucial for the precise production of components, enabling the formation of complex shapes and designs with excellent durability. Rubber product molding has several methods, among which rubber compression molding (PCM) uses a mold to heat and cure the rubber into a new shape to form the final product, offering advantages such as low cost and simple maintenance. Chinese patent CN114953302A discloses an automated molding equipment for rubber products and its usage method. This equipment has an upper mold base and a lower mold base. The lower mold base is located on a transport component, which transports the lower mold base. The upper mold base is lifted and lowered by a molding cylinder. The upper mold base contains multiple plates of different sizes and shapes, and the lower mold base contains corresponding grooves of different shapes and sizes. The same molding component can process rubber products of different shapes and sizes. However, when producing products of different specifications, the entire lower mold base needs to be replaced, which is time-consuming and labor-intensive, resulting in low production efficiency.

[0022] Please see Figures 1-4 A rubber product molding mechanism includes: a mold body 1, with a mold cavity opened on the top of the mold body 1.

[0023] A connecting protective mechanism 2 is installed on the mold body 1. The connecting protective mechanism 2 includes a mounting block 21, which is located on the left side of the mold body 1. The right side of the mounting block 21 contacts the left side of the mold body 1. A fixed shaft 22 is rotatably connected to a groove at the top of the mounting block 21 via a bearing. A protective plate 23, which cooperates with the mold body 1, is fixedly connected to the top of the fixed shaft 22. The bottom of the protective plate 23 contacts the top of the mold body 1. A connecting groove 24 is provided on the right side of the bottom of the protective plate 23. An extension plate 25 slides on the wall, and the bottom of the extension plate 25 contacts the top of the mold body 1. A connecting block 26 is fixedly connected to the left side of the inner wall of the connecting groove 24. A slide groove 27 is opened on the left side of the extension plate 25 and at the position corresponding to the connecting block 26. The right side of the connecting block 26 passes through the slide groove 27 and extends into it. A slider 28 is fixedly connected to the right side of the connecting block 26. The surface of the slider 28 slides in contact with the inner wall of the slide groove 27. An iron block 29 is located on the right side of the slider 28. A magnet 210 that matches the iron block 29 is fixedly connected to the right side of the inner wall of the slide groove 27.

[0024] The installation block 21, fixed shaft 22, protective plate 23, connecting groove 24, extension plate 25, connecting block 26, slide 27, slider 28, iron block 29 and magnet 210 work together to protect the casting mold, prevent the mold cavity from being exposed to the outside world when the casting mold is not in use, and prevent a large amount of dust and impurities from being generated in the mold cavity. Moreover, the position of the extension plate 25 can be extended or shortened according to the size of the mold. When the casting mold does not need to be protected, the extension plate 25 can be stored in the connecting groove 24, which improves applicability and flexibility.

[0025] A limiting and fixing mechanism 3 is installed on the mounting block 21. The limiting and fixing mechanism 3 includes a fixing groove 31 located on the left side of the mounting block 21. Two fixing rods 32 are fixedly connected to the bottom of the inner wall of the fixing groove 31, and the top ends of the fixing rods 32 are fixedly connected to the top of the inner wall of the fixing groove 31. A movable plate 33 is provided between the two fixing rods 32, and the movable plate 33 is slidably connected to the surfaces of the two fixing rods 32. A buffer spring 34 is sleeved on the surface of the fixing rods 32. A limiting block 35 is fixedly connected to the top of the movable plate 33. The protective plate 23... Two limiting grooves 36 are provided at the bottom to cooperate with the limiting block 35. The top of the limiting block 35 passes through the fixing groove 31 and the limiting groove 36 on the left side from bottom to top and extends into the interior of the limiting groove 36. A steel ball 37 is movably connected in the groove at the top of the limiting block 35. The left side of the moving plate 33 passes through the fixing groove 31 and extends to its outside. A pull plate 38 is fixedly connected to the left side of the moving plate 33. The side of the pull plate 38 near the mounting block 21 is in contact with the mounting block 21. Three fastening bolts 4 are provided on the left side of the mounting block 21 and are threadedly connected to the mold body 1.

[0026] Specifically, by loosening the fastening bolt 4, the mounting block 21 and the mold body 1 can be separated, allowing the connecting protective mechanism 2 to be disassembled and reused.

[0027] The stability of the position adjustment of the protective plate 23 is ensured by the cooperation of the fixed groove 31, fixed rod 32, moving plate 33, buffer spring 34, limiting block 35, limiting groove 36, steel ball 37 and pull plate 38.

[0028] In use, first push the extension plate 25 to the left. The extension plate 25 moves to the left within the connecting groove 24, causing the slider 28 to slide within the sliding groove 27. This causes the iron block 29 and the magnet 210 to attract each other, allowing the extension plate 25 to move completely into the connecting groove 24. Then, pull the pull plate 38 downwards. The pull plate 38 drives the moving plate 33 to press down on the buffer spring 34. The moving plate 33 drives the limiting block 35 downwards, causing the limiting block 35 to separate from the limiting groove 36. Finally, rotate the protective plate 23. The protective plate 23 rotates 180 degrees around the fixed shaft 22, so that the mold cavity of the mold body 1 is fully opened, and the steel ball 37 and the bottom of the protective plate 23 roll into contact. When the limiting block 35 and another limiting groove 36 overlap, the protective plate 23 has rotated 180 degrees. Through the restoring force of the buffer spring 34, the buffer spring 34 drives the limiting block 35 to move upward through the moving plate 33. The limiting block 35 is inserted into the limiting groove 36 to complete the limiting of the protective plate 23 after the position adjustment.
