[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-4 The present invention provides an embodiment of a rubber product mold that is easy to clean, including a lower mold 1, an upper mold 2 above the lower mold 1, a core groove inside the lower mold 1, a core mold 3 inside the core groove of the lower mold 1, the core mold 3 including a block 301 and a surrounding plate 302, the surrounding plate 302 being sleeved on the outside of the block 301, and a cavity inside the core mold 3.

[0025] The lower mold 1 has a detachable core mold 3 inside, forming a split design. During cleaning, the core mold 3 can be removed from the core groove of the lower mold 1 to clean the inside of the block 301 and the surrounding plate 302 separately. This allows for more direct and comprehensive access to the originally hard-to-clean corner areas, effectively removing rubber residues, greatly improving cleaning efficiency and quality, ensuring the production quality of subsequent rubber products, and enhancing the practicality of the mold.

[0026] Please see Figure 3 The lower mold 1 has symmetrical sliding grooves on both sides of the core groove inside, and the sliding grooves are connected to the core groove. A fixed pressure plate 7 is set inside the sliding groove of the lower mold 1. Both the sliding groove and the fixed pressure plate 7 are square, and the size of the fixed pressure plate 7 matches the size of the sliding groove. A threaded rod 8 is fixedly installed on one side of the fixed pressure plate 7. A cylindrical groove is set inside the lower mold 1 along one side of the sliding groove. One end of the threaded rod 8 extends into the inside of the cylindrical groove. A threaded cylinder 9 is set inside the cylindrical groove of the lower mold 1 along the outside of the threaded rod 8. The threaded rod 8 and the threaded cylinder 9 are threadedly connected. A column groove is set inside the lower mold 1 along one side of the cylindrical groove. A rotating column 10 is rotatably installed inside the column groove of the lower mold 1. The rotating column 10 is fixedly connected to one end of the threaded cylinder 9. An internal hexagonal groove is set inside the rotating column 10.

[0027] The core mold 3 is fixed by components such as the fixed pressure plate 7, threaded rod 8, threaded cylinder 9, and rotating column 10, so that the core mold 3 will not loosen or shift during the mold operation, thereby ensuring the molding quality of rubber products. When the core mold 3 needs to be disassembled and cleaned, the rotating column 10 is rotated, which drives the threaded cylinder 9 to rotate, and the threaded rod 8 to rotate and translate, thereby allowing the fixed pressure plate 7 to be moved away from the core mold 3, which increases its practicality.

[0028] Please see Figure 2 The lower part of the lower mold 1 has a bottom cavity that is connected to the core groove. An installation plate 4 is fixedly installed inside the bottom cavity of the lower mold 1. An electric cylinder 5 is fixedly installed below the installation plate 4. A push plate 6 is provided above the installation plate 4. The push rod end of the electric cylinder 5 slides through the installation plate 4 and is fixedly connected to the push plate 6.

[0029] When the core mold 3 needs to be disassembled and cleaned, the electric cylinder 5 can provide stable power to quickly push the push plate 6 upward to eject the core mold 3, which greatly shortens the disassembly time of the core mold 3 and increases its practicality.

[0030] Please see Figure 3 A pressure mold 11 is fixedly installed below the upper mold 2. A heating chamber is provided inside the pressure mold 11, and an electric heating wire 12 is fixedly installed inside the heating chamber of the pressure mold 11.

[0031] By setting an electric heating wire 12 inside the mold 11, the electric heating wire 12 can heat the mold 11 when energized, thereby heating the rubber product during the molding process, ensuring the vulcanization reaction, and allowing the rubber material to better fill the mold cavity, thus increasing its practicality.

[0032] Please see Figure 1 The lower mold 1 and the upper mold 2 are provided with side grooves at the four corners. A guide cylinder 14 is fixedly installed inside the side groove of the lower mold 1, and a guide post 13 is fixedly installed inside the side groove of the upper mold 2. The lower end of the guide post 13 slides into the interior of the guide cylinder 14.

[0033] By sliding the guide post 13 within the guide cylinder 14, the upper mold 2 and the lower mold 1 can be accurately aligned during the mold closing process, avoiding misalignment and ensuring the molding accuracy and dimensional consistency of the rubber products. Furthermore, the cooperation between the guide post 13 and the guide cylinder 14 can withstand the lateral force during mold closing, reducing friction and collision between molds, reducing mold wear, and extending the service life of the mold.

[0034] Working principle: During the production and molding process of rubber products, the rubber material is placed into the cavity of the lower mold 1, and then the mold is closed. The upper mold 2 moves down, and the guide pillars 13 at its four corners slide into the guide cylinders 14 at the corresponding corners of the lower mold 1. Through the sliding cooperation of the guide pillars 13 and guide cylinders 14, the upper and lower molds are accurately aligned, avoiding misalignment. Simultaneously, the heating wire 12 inside the compression mold 11 is energized and heats the compression mold 11, causing the rubber material to be heated and promoting the vulcanization reaction. This allows the rubber material to better fill the mold cavity, which is beneficial to the molding quality of the rubber product. When the core mold 3 needs... During cleaning, rotating the rotating column 10 drives the threaded cylinder 9 to rotate. The threaded rod 8 moves horizontally under the internal thread transmission of the threaded cylinder 9, causing the fixed pressure plate 7 to move away from the core mold 3 in the sliding groove, releasing the fixation of the core mold 3. Then, the electric cylinder 5 is started, and its push rod end pushes the push plate 6 upward, pushing the core mold 3 out of the core groove of the lower mold 1. After that, the core mold 3 can be taken out from the lower mold 1, and the inside of the block 301 and the surrounding plate 302 can be cleaned respectively. This can more directly and comprehensively reach the corner areas that are originally difficult to clean, effectively remove rubber residues, improve cleaning efficiency and quality, and benefit the quality of subsequent rubber product production.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
