Description

Technical Field

[0001] This utility model relates to the field of rubber pad production technology, specifically to a molding device for producing porous rubber pads. Background Technology

[0002] There are two main types of porous rubber mats on the market. One type is a one-piece porous rubber mat that is thermoplastically molded in one piece. The other type is a porous rubber granule mat made from various waste rubbers, which achieves waste recycling. After the recycled waste rubber products are crushed into rubber granules, the rubber granules and glue need to be mixed and stirred evenly in a certain proportion. Then, the evenly mixed gel-like mixture is taken out into a mold for pressure holding and cooling to form a porous rubber mat.

[0003] Currently, in the production of porous rubber pads, especially in the molding process, there is no dedicated molding equipment for porous rubber pads. A compression molding machine is used for pressing. During the molding process, the injected mixture may overflow due to the pressure of the compression block. Therefore, after molding, the edges of the porous rubber pad may be connected to the overflowing rubber, requiring secondary cleaning. This is time-consuming and labor-intensive, resulting in poor molding effect, complicated operation, and low work efficiency.

[0004] Therefore, it is particularly important to improve the existing molding device for producing porous rubber mats, design a new molding device for producing porous rubber mats to solve the above-mentioned technical defects, and improve the overall practicality of the molding device for producing porous rubber mats. Utility Model Content

[0005] The purpose of this invention is to provide a molding device for producing porous rubber pads. When molding porous rubber pads, the device moves the blades to both sides of the mold to remove excess rubber after extrusion, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A molding device for producing porous rubber pads includes a worktable, a drive block slidably connected to the top of the inner side of the worktable, a hydraulic rod inside the worktable with its output end fixedly connected to the drive block, an operating table fixedly connected to the bottom of the inner side of the worktable, a receiving groove inside the operating table with a mold slidably connected inside the receiving groove, an extension edge symmetrically fixedly connected to the outside of the mold, a mounting plate symmetrically fixedly connected to the outside of the worktable, a fixing plate fixedly connected to the outside of the mounting plate, a sliding plate slidably connected to the middle of the fixing plate, and a blade fixedly connected to the bottom of the sliding plate.

[0008] As a preferred embodiment of this utility model, a positioning block is fixedly connected to the middle of the fixed plate, a sliding groove is provided in the middle of the sliding plate, the sliding plate is slidably connected to the fixed plate through the positioning block, and toothed plates are fixedly connected symmetrically to the outside of the sliding plate.

[0009] As a preferred embodiment of this utility model, the fixed plate has limit grooves on both sides, and a linkage rod is slidably connected to the limit grooves. A fixed column is fixedly connected to the outside of the linkage rod, and a pawl is rotatably connected to the outside of the fixed column. A torsion spring is provided between the fixed column and the pawl, and the pawl extends into the tooth groove of the toothed plate.

[0010] As a preferred embodiment of this utility model, a swing rod is rotatably connected to the top of the fixed plate, and connecting rods are rotatably connected to both ends of the swing rod. The end of the connecting rod away from the swing rod is rotatably connected to the linkage rod.

[0011] As a preferred embodiment of this utility model, a frame is fixedly connected to the bottom of the inner side of the receiving groove, a square groove is opened inside the frame, and a moving block is slidably connected inside the square groove.

[0012] As a preferred embodiment of this utility model, a guide seat is fixedly connected to the top of the moving block, and a synchronizing rod is rotatably connected inside the guide seat. The synchronizing rod extends to the bottom of the mold and is rotatably connected to the mold. A shock-absorbing spring is fixedly connected to the bottom of the moving block and inside the square groove. A damper is provided inside the shock-absorbing spring.

[0013] As a preferred embodiment of this utility model, the frame is symmetrically fixedly connected to a placement frame, the placement frame is fixedly connected to a buffer ball, and the two sets of moving blocks are fixedly connected to an impact rod on the side that is far apart from each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, rubber raw material is placed inside the mold, which allows the drive block to enter the mold and compress the rubber. Then, the synchronizing rod is extended and pushes the moving block, which then slides inside the square groove and stretches the shock-absorbing spring. The energy storage of the shock-absorbing spring buffers the extrusion pressure on the mold, achieving a balanced press and preventing inconsistent rubber thickness after molding.

[0016] In this invention, the swing rod is manually squeezed, and then the swing rod moves repeatedly, generating a pulling force on the connecting rod. This causes the linkage rod to slide inside the limiting groove. Subsequently, the pawl moves synchronously and inserts into the tooth groove of the toothed plate, generating a pushing force on the toothed plate. During repeated movements, the slide plate slides, thereby adjusting the height of the blade and completing the cutting of excess material. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A molding device for producing porous rubber pads includes a worktable 1. A drive block 2 is slidably connected to the top of the inner side of the worktable 1. A hydraulic rod is provided inside the worktable 1, and the output end of the hydraulic rod is fixedly connected to the drive block 2. An operating table 3 is fixedly connected to the bottom of the inner side of the worktable 1. A receiving groove 4 is opened inside the operating table 3. A mold 5 is slidably connected inside the receiving groove 4. An extension side 6 is symmetrically fixedly connected to the outside of the mold 5. An installation plate 7 is symmetrically fixedly connected to the outside of the worktable 1. A fixing plate 8 is fixedly connected to the outside of the installation plate 7. A sliding plate 9 is slidably connected to the middle of the fixing plate 8. A blade 10 is fixedly connected to the bottom of the sliding plate 9. Rubber raw material is placed inside the mold 5. Then, the hydraulic rod is driven to press down the drive block 2 into the inside of the mold 5 and compress the rubber. By sliding the sliding plate 9, the height of the blade 10 is adjusted and it is located at the top of the extension side 6. When the rubber is compressed, the excess material contacts the blade 10 and is removed.

[0025] Furthermore, in this embodiment, a positioning block 11 is fixedly connected to the middle of the fixed plate 8, and a sliding groove is provided in the middle of the sliding plate 9. The sliding plate 9 is slidably connected to the fixed plate 8 through the positioning block 11. Toothed plates 12 are fixedly connected to the outside of the sliding plate 9. By sliding the sliding plate 9, the sliding groove will slide outside the positioning block 11, assisting the sliding plate 9 to move along a straight line.

[0026] Furthermore, in this embodiment, limiting grooves are provided on both sides of the fixed plate 8, and a linkage rod 13 is slidably connected to the limiting grooves. A fixed post is fixedly connected to the outside of the linkage rod 13, and a pawl 14 is rotatably connected to the outside of the fixed post. A torsion spring is provided between the fixed post and the pawl 14. The pawl 14 extends into the tooth groove of the toothed plate 12. A swing rod 15 is rotatably connected to the top of the fixed plate 8, and a connecting rod 16 is rotatably connected to both ends of the swing rod 15. The end of the connecting rod 16 away from the swing rod 15 is rotatably connected to the linkage rod 13. By manually squeezing the swing rod 15, the swing rod 15 moves repeatedly and generates a pulling force on the connecting rod 16, thereby enabling the linkage rod 13 to slide inside the limiting groove. Then, the pawl 14 moves synchronously and inserts into the tooth groove of the toothed plate 12, generating a pushing force on the toothed plate 12. During repeated movement, the slide plate 9 slides, thereby adjusting the height of the blade 10 and completing the cutting of excess material.

[0027] Furthermore, in this embodiment, a frame is fixedly connected to the bottom of the inner side of the receiving groove 4. A square groove is opened inside the frame. A moving block 17 is slidably connected inside the square groove. A guide seat 18 is fixedly connected to the top of the moving block 17. A synchronizing rod 19 is rotatably connected inside the guide seat 18. The synchronizing rod 19 extends to the bottom of the mold 5 and is rotatably connected to the mold 5. A shock-absorbing spring 20 is fixedly connected to the bottom of the moving block 17 and inside the square groove. A damper is provided inside the shock-absorbing spring 20. When the driving block 2 is pressed down, it will squeeze the mold 5, so that the mold 5 slides inside the receiving groove 4. Then, the synchronizing rod 19 is unfolded and pushes the moving block 17, so that the moving block 17 slides inside the square groove and stretches the shock-absorbing spring 20. The energy storage of the extension and contraction of the shock-absorbing spring 20 buffers the squeezing force on the mold 5, extends its service life, and at the same time realizes the equalization of the pressing machine and prevents the rubber thickness after molding from being inconsistent.

[0028] Furthermore, in this embodiment, a placement frame 21 is symmetrically fixedly connected to the frame, and a buffer ball 22 is fixedly connected inside the placement frame 21. An impact rod 23 is fixedly connected to the side of the two sets of moving blocks 17 that are far apart. As the moving blocks 17 slide, the impact rod 23 moves synchronously with the moving blocks 17. Then the impact rod 23 will impact the buffer ball 22 to dissipate the impact force.

[0029] In this embodiment, the specific implementation scenario is as follows: rubber raw material is placed inside the mold 5, and then the hydraulic rod is driven to press down the drive block 2 into the mold 5 and compress the rubber. Then, the synchronizing rod 19 is extended and pushes the moving block 17, which then slides inside the square groove and stretches the shock-absorbing spring 20. The extension and retraction of the shock-absorbing spring 20 buffers the extrusion pressure on the mold 5, extends its service life, and achieves balanced pressing to prevent inconsistent rubber thickness after molding. The swing rod 15 is manually squeezed, and then the swing rod 15 moves repeatedly and pulls the connecting rod 16, which then slides the linkage rod 13 inside the limiting groove. Then, the pawl 14 moves synchronously and inserts into the tooth groove of the toothed plate 12, which pushes the toothed plate 12. During repeated movement, the slide plate 9 slides, and then the height of the blade 10 is adjusted to complete the cutting of excess material.
