Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an irradiation processing mold that can improve the flexibility of biomedical membranes. Background Technology

[0002] In the production of biomedical membranes, irradiation processing is a crucial step, and its quality directly affects the performance of the biomedical membrane, especially its flexibility, which plays a decisive role in its application in the medical field. The irradiation processing mold, as the core equipment in this process, has its performance directly impacting the entire production process and product quality.

[0003] The prepared biomedical membrane raw materials are evenly injected into the mold cavity through a specific feeding device. Since the mold height is pre-adjusted, the amount of filling material can be precisely controlled, laying the foundation for the subsequent formation of a biomedical membrane of uniform thickness. After filling, the entire mold is transferred to the irradiation equipment. The irradiation source is turned on, allowing the biomedical membrane raw materials to be processed under specific irradiation doses and times. During irradiation, the mold structure must remain stable to prevent vibration or displacement from affecting the irradiation effect, ensuring that the molecular structure of the biomedical membrane undergoes the expected changes under irradiation, thereby improving its flexibility.

[0004] However, this traditional demolding method has certain problems. In actual irradiation processing, the internal space of the mold is often very limited, especially in production scenarios with strict requirements on mold volume. When the biomedical membrane needs to be demolded after processing, the limited space makes it difficult for existing simple ejection devices to function effectively, resulting in difficulty in smoothly removing the finished product. This not only consumes a lot of time and reduces production efficiency, but also damages the biomedical membrane during the removal process, affecting its flexibility and overall quality. Therefore, an irradiation processing mold that can improve the flexibility of biomedical membranes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an irradiation processing mold that can improve the flexibility of biomedical membranes, aiming to improve the problem that the finished product is difficult to remove during the demolding process due to space constraints.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An irradiation processing mold that can improve the flexibility of biomedical membranes includes an upper mold, an inlet hole inside the upper mold, multiple connecting columns fixedly connected to the bottom of the upper mold, stabilizing components provided on the outer walls of the connecting columns, a lower mold at the bottom of the upper mold, a template slidably connected inside the lower mold, and a demolding component at the bottom of the template.

[0008] The demolding assembly includes multiple connecting blocks. The top of each connecting block is fixedly connected to the bottom of the template. A support frame is fixedly connected to one side of the lower mold. A worm gear is rotatably connected inside the support frame. A rotating wheel is fixedly connected to the outer wall of the worm gear. A rotating shaft is rotatably connected inside the lower mold. Support plates are rotatably connected to both ends of the rotating shaft. The outer walls of the support plates are fixedly connected to both sides of the lower mold. A worm wheel is fixedly connected to the outer wall of the rotating shaft. The worm wheel meshes with the worm gear. Multiple connecting plates are fixedly connected to the outer wall of the rotating shaft. A transmission plate is rotatably connected inside each connecting plate. Each transmission plate is rotatably connected inside the connecting block.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the rotating shaft is rotatably connected to multiple support seats, the bottom of the support seats is fixedly connected to the bottom of the inner wall of the lower mold, and the support seats are in contact with the connecting plate;

[0011] As a further description of the above technical solution:

[0012] The bottom of the template is fixedly connected to multiple connecting cylinders, and each connecting cylinder is slidably connected to a limit post inside. The bottom of the limit post is fixedly connected to the bottom of the inner wall of the lower mold.

[0013] As a further description of the above technical solution:

[0014] The stabilizing component includes multiple square blocks, which are located on the outer wall of the connecting column, and each connecting column has a fixed column fixedly connected to its inner wall.

[0015] As a further description of the above technical solution:

[0016] Each of the fixed columns has multiple connecting rings slidably connected inside, and each of the connecting rings has a transmission plate rotatably connected to both sides.

[0017] As a further description of the above technical solution:

[0018] Each of the two outer walls of the transmission plate on each side is rotatably connected to a rubber clamping plate, and one side of each rubber clamping plate is fixedly connected to the outer wall of the square clamping block.

[0019] As a further description of the above technical solution:

[0020] The square card engages with the interior of the lower mold, and the rubber card adheres to the inner wall of the lower mold.

[0021] As a further description of the above technical solution:

[0022] Each of the fixed columns is provided with a spring on its outer wall. One end of the spring is fixedly connected to the outer wall of the connecting ring, and the other end of the spring is fixedly connected to the inner wall of the connecting column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the template is pushed upward inside the lower mold by rotating the wheel, and the height of the template is fixed by the self-locking property between the worm and the worm wheel. At the same time, the moving direction of the template is limited by the sliding of the connecting cylinder on the outer wall of the limiting column, so as to achieve the demolding process of the equipment. This solves the problem that the finished product is difficult to take out due to space limitation during the demolding process, and improves the demolding efficiency of the equipment.

[0025] 2. In this utility model, the upper mold position is fixed by the rubber plate fitting against the inside of the lower mold and the square block engaging with a specific slot inside the lower mold. This solves the problem that during the use of the equipment, there is a certain gap between the connecting column and the lower mold, which can easily lead to displacement of the upper mold and affect the use effect of the equipment. This enhances the stability of the upper mold during use. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides an irradiation processing mold that can improve the flexibility of biomedical membranes, including an upper mold 1, an inlet hole 3 inside the upper mold 1, a plurality of connecting columns 17 fixedly connected to the bottom of the upper mold 1, a stabilizing component on the outer wall of the connecting columns 17, a lower mold 2 at the bottom of the upper mold 1, a template 4 slidably connected inside the lower mold 2, and a demolding component at the bottom of the template 4.

[0034] The demolding assembly includes multiple connecting blocks 14. The top of each connecting block 14 is fixedly connected to the bottom of the template 4, serving to support and fix the template 4. A support frame 5 is fixedly connected to one side of the lower mold 2, providing stable support for the entire structure and helping to bear the weight and operating force of the components above it. A worm gear 6 is rotatably connected inside the support frame 5. The worm gear 6 plays a transmission role during demolding, converting rotational force into linear motion to drive other components. A rotating wheel 7 is fixedly connected to the outer wall of the worm gear 6, and the rotation of the rotating wheel 7 provides power to the worm gear 6, ensuring its effective operation. A rotating shaft 9 is rotatably connected inside the lower mold 2, responsible for bearing and transmitting rotational motion. Support plates 10 are rotatably connected to both ends of the rotating shaft 9. The outer walls of the support plates 10 are fixedly connected to both sides of the lower mold 2, enhancing the overall stability of the lower mold 2 and providing additional support. A worm wheel 8 is fixedly connected to the outer wall of the rotating shaft 9, and the worm wheel 8 meshes with the worm gear 6 to achieve effective power transmission. Multiple connecting plates 12 are fixedly connected to the outer wall of the rotating shaft 9. Each connecting plate 12 has a rotatably connected transmission plate 13 inside. The transmission plate 13 is responsible for converting the movement of the worm gear 6 into the movement of the template 4, ensuring a smooth demolding process. Each transmission plate 13 is rotatably connected inside a connecting block 14, allowing the connecting block 14 to move flexibly. Multiple support seats 11 are rotatably connected to the outer wall of the rotating shaft 9. The bottom of the support seats 11 is fixedly connected to the bottom of the inner wall of the lower mold 2, providing necessary support and stability for the rotating shaft 9. The support seats 11 and connecting plates 12 are in close contact, ensuring precise alignment and stable fixation during movement. Multiple connecting cylinders 16 are fixedly connected to the bottom of the template 4. Each connecting cylinder 16 has a slidingly connected limit post 15 inside. The bottom of the limit post 15 is fixedly connected to the bottom of the inner wall of the lower mold 2, used to restrict and guide the movement of the template 4, ensuring no deviation during demolding, further improving demolding efficiency and safety.

[0035] Specifically, during the demolding process, the rotation of the rotating wheel 7 drives the worm wheel 8 at the bottom of the worm gear 6 to rotate. This rotational force is effectively transmitted to the surface of the connecting plate 12 on the outer wall of the rotating shaft 9. As the rotation continues, the connecting block 14 on the outer wall of the transmission plate 13 moves upward, thereby enabling the mold inside the template 4 to be smoothly removed from the lower mold 2, completing the demolding process. Simultaneously, the movement of the template 4 causes the connecting cylinder 16 to slide along the outer wall of the limiting post 15. This design aims to effectively limit the movement direction of the template 4, ensuring its stability during the demolding process, preventing deviation from the predetermined trajectory, significantly improving the demolding efficiency of the equipment, and ensuring a smooth and efficient production process.

[0036] Reference Figure 2 and Figure 4 The stabilizing component includes multiple square locking blocks 21 located on the outer wall of the connecting column 17, enhancing its stability and providing support. Each connecting column 17 has a fixed column 23 fixedly connected to its inner wall, providing a stable mounting base for the connecting ring 18 and ensuring it does not wobble during operation. Multiple connecting rings 18 are slidably connected inside each fixed column 23, interacting with the transmission plate 29 to transmit force and guide movement. Each connecting ring 18 is rotatably connected to both sides of the transmission plate 29, whose design allows the connecting ring 18 to rotate freely, improving the component's flexibility and response speed. Each side of the transmission plate 29 has a rotatably connected rubber clamping plate 20, which enhances the fixing effect through friction, preventing displacement of components during operation. Each rubber clamping plate 20 is fixedly connected to the outer wall of the square locking block 21 on one side, further strengthening the bond between the square locking block 21 and the lower mold 2. The square locking block 21 engages with the interior of the lower mold 2, ensuring that the upper mold 1 will not accidentally slide or fall off during operation, thus improving the safety of the mold during use. The rubber locking plate 20 fits against the inner wall of the lower mold 2, utilizing the high friction properties of rubber to increase overall stability. Each fixing post 23 has a spring 22 on its outer wall. The function of the spring 22 is to provide additional elastic support, ensuring that the connecting ring 18 can be appropriately displaced under force, thereby maintaining the flexibility of the component. One end of the spring 22 is fixedly connected to the outer wall of the connecting ring 18, and the other end is fixedly connected to the inner wall of the connecting post 17, forming a closed support component. This allows the connecting ring 18 to quickly return to its original position under the action of the spring 22, even under a certain impact force during operation, ensuring the stability and reliability of the component.

[0037] Specifically, during equipment operation, the operator first moves the upper mold 1 to the top of the lower mold 2. Then, the connecting column 17 is precisely moved to the hole position inside the lower mold 2. Through the hole inside the lower mold 2, the connecting column 17 effectively pushes the square locking block 21 and the rubber locking plate 20 towards the connecting column 17, achieving linkage between components. During this movement, the rubber locking plate 20 not only slides forward but also acts on the connecting ring 18 through the transmission plate 2 19, thereby compressing the spring 22. This mechanism ensures precise component alignment and prepares the conditions for subsequent fixing. When the square locking block 21 moves to a specific slot position, the rebound force of the spring 22 will push the square locking block 21 to engage with the slot inside the lower mold 2, thus achieving stable fixing of the upper mold 1. Simultaneously, the rubber locking plate 20 tightly fits into the hole inside the lower mold 2. Due to its high friction characteristics, the rubber locking plate 20 significantly enhances the stability of the upper mold 1 during use, ensuring safe and efficient equipment operation.

[0038] Working principle: During the demolding process, the rotating wheel 7 drives the worm wheel 8 at the bottom of the worm gear 6 to rotate. This rotational force is transmitted to the surface of the connecting plate 12 on the outer wall of the rotating shaft 9, causing the connecting block 14 on the outer wall of the transmission plate 13 to move upward, thereby pushing the mold inside the template 4 out of the lower mold 2 to achieve demolding. While the template 4 is moving, it will drive the connecting cylinder 16 to slide on the outer wall of the limiting post 15, which limits the movement direction of the template 4 and prevents the template 4 from deviating from the predetermined trajectory, thus improving the demolding efficiency of the equipment.

[0039] During equipment use, the upper mold 1 is moved to the top of the lower mold 2, and the connecting column 17 is moved to the internal hole of the lower mold 2. The internal hole of the lower mold 2 is used to push the square locking block 21 and the rubber locking plate 20 to move towards the connecting column 17. While the rubber locking plate 20 is moving, it will push the connecting ring 18 to compress the spring 22 through the transmission plate 2 19. When the square locking block 21 moves to a specific slot, the rebound force of the spring 22 will push the square locking block 21 to engage with the internal slot of the lower mold 2, thereby fixing the position of the upper mold 1. In this process, the rubber locking plate 20 will be pushed to fit into the internal hole of the lower mold 2. The high friction characteristics of the rubber locking plate 20 will enhance the stability of the upper mold 1 during use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
