Description

Technical Field

[0001] This utility model relates to the field of plastic molding die technology, and in particular to a multi-cavity injection mold for sports shoe soles. Background Technology

[0002] As a product with huge global consumption, the large-scale production efficiency and cost control of athletic shoes soles have become the core competitive areas for manufacturers. Injection molding is the mainstream process for producing polymer soles, and its core equipment is the injection mold. However, only one sole can be injected at a time during the production process, which affects production efficiency and results in low capacity. Therefore, multi-cavity module injection molds for athletic shoe soles have emerged.

[0003] Existing technologies often require numerous cumbersome fixed operations or rely on complex adjustment components when changing molds, resulting in a long replacement process, increased equipment downtime, and a relatively slow response to changes in market orders. This, to some extent, restricts factory capacity and market competitiveness. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-cavity module injection mold for sports shoe soles, which aims to improve the problem of slow response speed in order to market orders due to the long time required for mold change.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-cavity module injection mold for sports shoe soles, comprising a base plate, a support block fixedly connected to the upper surface of the base plate, an injection molding plate slidably connected to the inner wall of the support block, a cavity formed on the upper surface of the injection molding plate, a fixing block fixedly connected to the outer wall of the support block, a rotating plate rotatably connected to the inside of the fixing block, a pressing shaft fixedly connected to the outer wall of the rotating plate, the outer wall of the pressing shaft fitting against the outer wall of the injection molding plate, a rotating shaft rotatably connected to the inside of the fixing block, the outer wall of the rotating shaft slidably connected to the inner wall of the rotating plate, a fixing plate fixedly connected to the outer wall of the rotating shaft, and the outer wall of the fixing plate rotatably connected to the outer wall of the rotating plate, a bracket fixedly connected to the upper surface of the base plate, and a pressing assembly provided on the lower surface of the bracket, the pressing assembly being used for the pressing assistance device injection molding.

[0006] The above technical solution involves an injection molding plate with a cavity on its upper surface for injection molding of the shoe sole. The rotating plate can be rotated inside the fixed block by lifting it. When the rotating plate rotates, it drives the lower pressure shaft to rotate synchronously, thereby fixing the injection molding plate by the lower pressure shaft. This allows for quick mold replacement and significantly reduces downtime.

[0007] Preferably, the pressing assembly includes a hydraulic rod, the upper surface of which is fixedly connected to the inner top wall of the bracket, the output end of which is fixedly provided with a pressing mold, the output end of which is slidably connected to a connecting rod, the outer wall of which is slidably connected to the inside of the pressing mold, and the lower surface of the pressing mold is in contact with the upper surface of the injection molded plate.

[0008] Preferably, an extension plate is fixedly connected to the lower surface of the injection molding plate, and a support plate is fixedly connected to the upper surface of the extension plate.

[0009] Preferably, a tie rod is rotatably connected inside the support plate, and a connecting plate is fixedly connected to the outer wall of the tie rod.

[0010] Preferably, the outer wall of the pull rod is rotatably connected to an outer plate, and the outer wall of the outer plate is fixedly connected to a top plate.

[0011] Preferably, the outer wall of the ejector plate is slidably connected to the inner wall of the injection molded plate, and one end of the spring is fixedly connected to the lower surface of the ejector plate.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figures 1-3 This utility model provides an embodiment of a multi-cavity module sports shoe sole injection mold, including a base plate 1, a support block 2 fixedly connected to the upper surface of the base plate 1, an injection plate 3 slidably connected to the inner wall of the support block 2, a cavity 12 opened on the upper surface of the injection plate 3, a fixing block 4 fixedly connected to the outer wall of the support block 2, a rotating plate 5 rotatably connected to the inside of the fixing block 4, a pressing shaft 6 fixedly connected to the outer wall of the rotating plate 5, the outer wall of the pressing shaft 6 being in contact with the outer wall of the injection plate 3, a rotating shaft 7 rotatably connected to the inside of the fixing block 4, the outer wall of the rotating shaft 7 slidably connected to the inner wall of the rotating plate 5, a fixing plate 8 fixedly connected to the outer wall of the rotating shaft 7, the outer wall of the fixing plate 8 rotatably connected to the outer wall of the rotating plate 5, a bracket 9 fixedly connected to the upper surface of the base plate 1, and a pressing component provided on the lower surface of the bracket 9, the pressing component being used for the pressing assistance device injection molding; Specifically, the base plate 1 supports and fixes the support block 2, allowing the injection molding plate 3 to slide against the inner wall of the support block 2. A cavity 12 is formed on the upper surface of the injection molding plate 3. The support block 2 supports and limits the sliding of the injection molding plate 3, and also supports and fixes the fixing block 4. The rotating plate 5 supports and fixes the lower pressure shaft 6. When the rotating plate 5 is lifted and rotated inside the fixing block 4, the fixing block 4 supports and limits the rotation of the rotating plate 5. When the rotating plate 5 rotates, it drives the lower pressure shaft 6 to rotate synchronously and fit against the injection molding plate 3. The outer wall, and when the rotating plate 5 rotates, the rotating shaft 7 will slide into the inner wall of the rotating plate 5. The rotating shaft 7 supports and fixes the fixed plate 8. Twisting the rotating shaft 7 makes the fixed plate 8 rotate on the outer wall of the rotating plate 5, so that the rotating plate 5 fixes the injection plate 3 through the lower pressure shaft 6. This allows for quick mold replacement, which can greatly shorten downtime, significantly improve equipment utilization, flexibly adapt to multi-variety and small-batch production, and quickly respond to changes in market orders, thereby enhancing the factory's production capacity and market competitiveness. The base plate 1 supports and fixes the bracket 9.

[0020] Reference Figure 1 , Figure 2 and Figure 4 The pressing assembly includes a hydraulic rod 10, the upper surface of which is fixedly connected to the inner top wall of the bracket 9. A pressing mold 11 is fixedly provided at the output end of the hydraulic rod 10. A connecting rod 22 is slidably connected to the output end of the hydraulic rod 10. The outer wall of the connecting rod 22 is slidably connected to the inside of the pressing mold 11. The lower surface of the pressing mold 11 is in contact with the upper surface of the injection molded plate 3. Specifically, the bracket 9 supports and fixes the hydraulic rod 10, ensuring the stability of the hydraulic rod 10 during operation. When the hydraulic rod 10 is started, it drives the lower mold 11 at the output end to push, thereby causing the lower mold 11 to press down and cooperate with the cavity 12 to inject the sports shoe sole. The connecting rod 22 is pulled out to remove the interior of the hydraulic rod 10, so that the upper template can be replaced.

[0021] Reference Figure 1 and Figure 5 An extension plate 13 is fixedly connected to the lower surface of the injection molding plate 3, and a support plate 14 is fixedly connected to the upper surface of the extension plate 13. A pull rod 15 is rotatably connected inside the support plate 14. A connecting plate 16 is fixedly connected to the outer wall of the pull rod 15. An outer connecting plate 17 is rotatably connected to the outer wall of the pull rod 15. An ejector plate 18 is fixedly connected to the outer wall of the outer connecting plate 17. The outer wall of the ejector plate 18 is slidably connected to the inner wall of the injection molding plate 3. One end of a spring 19 is fixedly connected to the lower surface of the ejector plate 18, and the other end of the spring 19 is fixedly connected to the upper surface of the extension plate 13. Specifically, the injection molding plate 3 supports and fixes the extension plate 13, and the extension plate 13 supports and fixes the support plate 14. The pressing connecting plate 16 rotates inside the support plate 14 via the pull rod 15, and the support plate 14 supports the rotation of the pull rod 15. The injection molding plate 3 limits the rotation of the pull rod 15. The ejector plate 18 supports and fixes the outer plate 17, so that when the pull rod 15 rotates, the outer plate 17 rotates and rises. When the outer plate 17 rises, it drives the ejector plate 18 to slide on the inner wall of the injection molding plate 3. The injection molding plate 3 supports and fixes the ejector plate 17. The ejector plate 18 serves to support the sliding motion. When the ejector plate 18 rises, it protrudes from the inner wall of the cavity 12, smoothly pushing out the sole. One end of the spring 19 is fixed by the ejector plate 18, and the other end of the spring 19 is fixed by the extension plate 13. When the pressing connecting plate 16 is released, the spring force of the spring 19 pulls the ejector plate 18 back to its original position, thus smoothly pushing out the sole. This makes it easy for personnel to quickly grab the sole, reducing difficulties in picking up the product due to the sole being tilted or stuck. This improves the picking efficiency and reduces the workload of the staff, making the picking process smoother and balancing production efficiency and staff comfort.

[0022] Example 2: Reference Figure 6 The outer wall of the support block 2 is rotatably connected to a rotating shaft 20, the outer wall of the rotating shaft 20 is fixedly connected to an inclined plate 21, and the outer wall of the inclined plate 21 is rotatably connected to the outer wall of the injection molded plate 3. Specifically, the rotating shaft 20 supports and fixes the inclined plate 21. Rotating the rotating shaft 20 causes the inclined plate 21 to rotate. The inclined plate 21 has an inclination. When the inclined plate 21 rotates, it fixes the injection molding plate 3 through the inclined structure, which allows for quick mold replacement, greatly shortens downtime, significantly improves equipment utilization, flexibly adapts to multi-variety and small-batch production, and quickly responds to changes in market orders, thereby enhancing the factory's production capacity and market competitiveness.

[0023] Working principle: When the device is needed, the injection plate 3 is pushed to slide on the inner wall of the support block 2, and the rotating plate 5 is lifted to rotate through the fixed block 4. The rotating plate 5 is fixed to the injection plate 3 by the lower pressure shaft 6. When the rotating plate 5 rotates, it will drive the rotating shaft 7 into the inner wall of the rotating plate 5. Twisting the rotating shaft 7 will drive the fixed plate 8 to rotate synchronously and be fixed on the outer wall of the rotating plate 5. The connecting rod 22 is pulled to disengage from the hydraulic rod 10 through the lower pressure mold 11, so that the mold can be changed quickly. This can greatly shorten the downtime, significantly improve the equipment utilization rate, flexibly adapt to multi-variety and small-batch production, reduce mold change operation errors, ensure product consistency, reduce production capacity loss caused by downtime, and quickly respond to changes in market orders, thereby enhancing the factory's production capacity and market competitiveness. After the device is replaced, the hydraulic rod 10 on the lower surface of the starter bracket 9 pushes the lower mold 11 at the output end, which works in conjunction with the cavity 12 on the upper surface of the injection plate 3 to inject the shoe sole. The pressing connecting plate 16 rotates inside the support plate 14 through the pull rod 15, so that when the pull rod 15 rotates, the ejector plate 18 rises and slides inside the injection plate 3 through the outer plate 17. When the ejector plate 18 rises, it protrudes from the inner wall of the cavity 12. When the pressing connecting plate 16 is released, the ejector plate 18 is reset by the elastic force of the spring 19, so that the shoe sole can be smoothly ejected, making it convenient for personnel to grab quickly and reducing the difficulty of picking up the parts caused by the shoe sole being crooked or stuck. This improves the picking efficiency and reduces the workload of the operators, making the picking process smoother and taking into account both production efficiency and personnel comfort.
