Description

Technical Field

[0001] This utility model relates to the field of membrane shell manufacturing technology, specifically to a membrane shell casting plate. Background Technology

[0002] In membrane housing manufacturing, the end is typically produced using a casting process. In this process, the casting plate is a tooling used to fix the water distributor and guide the casting material into the mold. For a long time, the structural design of casting plates in the industry has been relatively simple. Firstly, the unreasonable layout of functional components easily leads to uneven casting pressure and poor distribution of casting material, thus reducing the quality of the finished product. Secondly, traditional casting plates are made from plastic or metal alloy materials. While plastic casting is cheaper, it lacks structural strength and has a short service life; while metal alloy casting plates have a longer service life, their cost is higher. Thirdly, both of these require applying grease to the surface before each use to separate the cured epoxy resin, which is not only complicated but also introduces grease pollution, affecting product appearance and environmental cleanliness. The root cause of these problems is that traditional casting plate designs fail to systematically and rationally arrange multiple functions, lacking an integrated, multi-functional, and coating-free structural solution.

[0003] Therefore, how to provide a membrane casting plate that overcomes the defects of existing structures is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, this utility model provides a membrane casting plate to solve the problems of uneven casting quality, poor structural stability and cumbersome demolding operation in the prior art.

[0015] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0016] Please refer to Figures 1-5 The present invention will now describe a membrane casting plate, as follows: Figures 1-3The device includes a disc body 1, a positioning protrusion 2, a first casting tube 3, a second casting tube 4, and a through tube 5. The positioning protrusion 2 is installed at the center of the top of the disc body 1. Several first casting tubes 3 are installed at the bottom of the disc body 1, and the first casting tubes 3 are located outside the positioning protrusion 2. Several second casting tubes 4 are installed in the disc body 1, and the second casting tubes 4 are located outside the positioning protrusion 2. The bottom of the second casting tubes 4 extends out of the disc body 1, and the bottom of the second casting tubes 4 is slightly higher than the first casting tubes 3. Several through tubes 5 are inserted in the second casting tubes 4. The distance from the center of the first casting tube 3 to the center of the disc body 1 is equal to the distance from the center of the second casting tube 4 to the center of the disc body 1.

[0017] The usage process of this utility model embodiment is as follows: First, the casting plate is positioned and securely installed on the workbench using the limiting protrusion 17 on the outer wall of the plate body 1, ensuring the stability of the overall structure. Then, the water distributor is installed on the positioning protrusion 2 in the center of the plate body 1. The casting process is divided into two steps: during the first casting, the casting material is evenly injected through the first casting pipe 3 under the guidance of the guide plate 12 on the upper surface of the plate body 1, forming the bottom casting structure. After preliminary curing, the casting material for the second casting is poured in through the combination channel of the second casting pipe 4 and the detachable through pipe 5, completing the overall casting. After all the casting material has cured, the worker cuts along the pre-reserved cutting groove 14 on the side wall of the plate body 1, neatly separating the casting plate from the finished product. The detachable through pipe 5 facilitates the transportation and storage of the casting plate, while the cross-shaped reinforcing ribs 18 in the lower part of the plate body 1 enhance the stability of the entire structure. This design includes multiple functions such as multi-stage casting, component positioning, structural reinforcement, and convenient demolding, significantly improving the efficiency and quality of membrane shell production.

[0018] In a specific embodiment, such as Figures 4-5The disc body 1 includes a disc outer shell 11, a guide plate 12, a central disc 13, a cutting groove 14, a first casting hole 15, a second casting hole 16, a limiting protrusion 17, and reinforcing ribs 18. The guide plate 12 is integrally formed on the lower inner side of the disc outer shell 11. The central disc 13 is integrally formed at the center of the guide plate 12, and a mounting hole is opened in the center of the central disc 13. The positioning protrusion 2 is installed in the mounting hole. The cutting groove 14 is formed on the outer side wall of the disc outer shell 11. The first casting hole 15 penetrates the upper and lower walls of the guide plate 12 and is located outside the positioning protrusion 2. The second casting hole 16... Hole 16 penetrates the upper and lower walls of the outer shell 11 and the guide plate 12. The second casting hole 16 is located outside the positioning protrusion 2. The limiting protrusion 17 is installed at the bottom of the outer shell 11 and is integrally formed with the outer shell 11. Several reinforcing ribs 18 are installed below the outer shell 11 and the guide plate 12. One end of the reinforcing ribs 18 is connected to each other, and the other end of the reinforcing ribs 18 is fixed to the inner wall of the limiting protrusion 17. The distance from the center of the first casting hole 15 to the center of the outer shell 11 is equal to the distance from the center of the second casting hole 16 to the center of the outer shell 11. The outer shell 11 serves as a support to support and connect other components. The reinforcing ribs 18 installed on its lower surface are designed in a star-shaped distribution in this embodiment. They are used to bear and disperse the pressure generated by the casting material during the casting process, thereby enhancing the stability of the overall structure. The guide plate 12 provides a channel for the flow of casting material during the first casting, allowing it to be evenly spread across the bottom layer of the casting plate. The central plate 13 is used to install the positioning protrusion 2. The cutting groove 14 is a pre-fabricated cutting line, facilitating neat cutting of the membrane shell and casting plate by workers after casting, making demolding easier. The first casting hole 15 and the second casting hole 16 are channels for staged casting and also provide a structural foundation for the first casting tube 3 and the second casting tube 4. The limiting protrusion 17, on the one hand, cooperates with the worktable to provide positioning and fixation, and on the other hand, it works with the reinforcing rib 18 to provide support for the casting plate, improving the overall structural stability. These components together ensure the high efficiency, precision, and reliability of membrane shell casting production.

[0019] In a specific embodiment, such as Figure 2 The first casting pipe 3 and the first casting hole 15 are integrally formed. The upper end of the first casting pipe 3 is flush with the upper surface of the disc 1, providing structural feasibility for the first casting of the casting material. The integrated design significantly improves the overall structure and sealing performance, effectively preventing leakage of the casting material during the casting process, thereby improving the stability of the casting process and the quality consistency of the finished membrane shell.

[0020] In a specific embodiment, such as Figure 1The second casting pipe 4 and the second casting hole 16 are integrally formed. The integrated design ensures the integrity and sealing of the channel, preventing material leakage during secondary casting. At the same time, the upper end of the second casting pipe 4 protrudes from the upper surface of the disc 1, forming a clear structural difference with the first casting pipe 3, so that the casting material of the first casting will not block the second casting pipe, ensuring the integrity and molding quality of the finished membrane shell.

[0021] In one specific embodiment, both the first casting pipe 3 and the second casting pipe 4 have a conical structure. The conical design, which is wider at the top and narrower at the bottom, makes the pipe opening easier to identify and facilitates the glue injection operation. At the same time, the natural slope formed by this structure after the casting material has solidified makes the casting plate separate from the molded part more smoothly.

[0022] In a specific embodiment, such as Figure 4 An annular groove 21 is provided on the outer wall of one end of the top of the positioning protrusion 2. The annular groove 21 is used to enhance the sealing between the positioning protrusion 2 and the water distributor. Its groove design increases the contact area and provides mechanical engagement to prevent the water distributor from shifting or loosening during the casting process. This design improves the stability of the casting process.

[0023] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
