Description

Technical Field

[0001] This utility model relates to the field of fiberglass flange production technology, and in particular to a mold for forming fiberglass flanges using vacuum adsorption. Background Technology

[0002] Fiberglass flanges are widely used in chemical, environmental protection and other fields due to their advantages such as being lightweight and corrosion resistant. Vacuum adsorption molding process has become a key technology in the manufacturing of fiberglass flanges because it can precisely control the shape and size of the flanges. Developing efficient and stable vacuum adsorption molding molds is of great significance for improving the quality and production efficiency of fiberglass flanges.

[0003] In existing technologies, vacuum adsorption molding molds for FRP flanges mostly involve setting a sealing structure in the mold cavity, using an external vacuum pump to extract air from the cavity to create negative pressure, and using atmospheric pressure to tightly press the FRP raw material into the mold cavity to achieve molding. The precise dimensions and surface accuracy of the mold cavity ensure the specifications and appearance of the flange after molding.

[0004] However, existing mold vacuum interface connections mostly rely on traditional threaded connections. When changing molds, manual screw tightening is required repeatedly, which is cumbersome and time-consuming. Furthermore, inaccurate thread alignment can affect connection efficiency and sealing. In frequent mold change scenarios, this greatly slows down the production pace, increases labor costs and the probability of operational errors. There is an urgent need to optimize the vacuum interface connection method to improve the convenience and efficiency of mold changes. To address this, a method is proposed that uses vacuum adsorption to form a fiberglass flange mold to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mold for forming FRP flanges using vacuum adsorption, aiming to improve the problem that the vacuum interface of the existing vacuum adsorption type FRP flange forming mold uses traditional threaded connection, which leads to cumbersome and time-consuming mold changing operations and affects connection efficiency and sealing performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mold for forming fiberglass flanges using vacuum adsorption includes a lower mold, an upper mold at the top of the lower mold, multiple vacuum ports inside the lower mold, a connecting pipe slidably connected to one end of each of the multiple vacuum ports, and a connecting component on the outer wall of each of the multiple vacuum ports. The connecting assembly includes a first connecting ring and a second connecting ring. Both the first connecting ring and the second connecting ring are slidably connected to the outer wall of the vacuum interface. Sealing rings are fixedly connected to the inner walls of both the first connecting ring and the second connecting ring. Multiple fixing blocks are fixedly connected to the outer wall of the first connecting ring. Sliding columns are slidably connected inside each of the multiple fixing blocks. Each of the multiple sliding columns has a protruding column on its outer wall. Each of the multiple fixing blocks has a left-right symmetrical limiting ball. The limiting ball engages with the internal groove of the second connecting ring. The protruding columns on the outer walls of the multiple sliding columns are in contact with the outer walls of the limiting balls. A recovery assembly is provided on the outer walls of the multiple sliding columns. A demolding assembly is provided inside the lower mold.

[0007] As a further description of the above technical solution: The demolding assembly includes a fixed plate and a support plate, and the lower surfaces of the fixed plate and the support plate are both fixedly connected to the inner wall of the lower mold.

[0008] As a further description of the above technical solution: A motor is fixedly connected inside the fixing plate, and a shaped block is fixedly connected to the output end of the motor.

[0009] As a further description of the above technical solution: The other side of the irregularly shaped block is rotatably connected inside the support plate, and a transmission rod is slidably connected to the outer wall of the irregularly shaped block.

[0010] As a further description of the above technical solution: A connecting plate is fixedly connected to the top of the transmission rod, and multiple elastic columns are fixedly connected to the upper surface of the connecting plate.

[0011] As a further description of the above technical solution: All of the aforementioned elastic columns are made of rubber, and a spring is fitted on the outer wall of the transmission rod.

[0012] As a further description of the above technical solution: One end of the spring is fixedly connected to the lower surface of the connecting disc, and the other end is fixedly connected to the side wall of the transmission rod.

[0013] As a further description of the above technical solution: The recovery assembly includes a spring, which is fitted onto the outer wall of the sliding column. One end of the spring is fixedly connected to the inner wall of the fixing block, and the other end is fixedly connected to the side wall of the sliding column.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pulling the sliding column to compress the spring, the spring undergoes elastic deformation. Then, the elastic restoring force pushes the sliding column back to its original position, thereby compressing the limiting ball and locking it into the connecting ring. This achieves the effect of quickly connecting the vacuum interface, thus solving the problems of cumbersome mold changing operation and unstable sealing in the traditional connection method of vacuum interface, and improving the mold changing efficiency and the stability of the vacuum system operation.

[0015] 2. In this utility model, the motor drives the irregular block to rotate, which in turn drives the transmission rod to move upward, causing the elastic column to push out of the mold, thereby achieving the effect of assisted demolding. This solves the problem of easy deformation and laborious operation when using hard prying to demold FRP flanges, and improves demolding efficiency and flange product qualification rate.

Detailed Implementation

[0018] 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.

[0019] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a mold for forming a fiberglass flange using vacuum adsorption, comprising a lower mold 1, which is a horizontally placed block structure with a cavity at its top that matches the shape of the fiberglass flange. The surface of the cavity is precision-polished to ensure the surface accuracy of the formed flange. An upper mold 2 is provided at the top of the lower mold 1. The upper mold 2 has matching protrusions at the corresponding positions of the cavity of the lower mold 1, which can form a closed forming space with the lower mold 1 when the mold is closed. Multiple vacuum interfaces 3 are provided inside the lower mold 1. One end of each vacuum interface 3 is connected to a venting channel inside the cavity, and the other end extends to the outside of the lower mold 1 and is slidably connected to a connecting pipe 4. The end of the connecting pipe 4 away from the vacuum interface 3 can be connected to a vacuum pump through a hose. Each of the multiple vacuum interfaces 3 is slidably connected to a connecting pipe 4 at one end. Each of the multiple vacuum interfaces 3 has a connecting component on its outer wall to facilitate the connection of the vacuum interfaces 3 by the user. The connecting assembly includes a first connecting ring 5 and a second connecting ring 6. Both connecting ring 5 and second connecting ring 6 are slidably connected to the outer wall of the vacuum interface 3. Both connecting ring 5 and second connecting ring 6 are annular structures and are slidably fitted onto the outer wall of the vacuum interface 3 for easy connection by the user. A sealing ring 11 is fixedly connected to the inner wall of both connecting ring 5 and second connecting ring 6. The sealing ring 11 is annular and fits tightly against the outer wall of the vacuum interface 3, effectively enhancing the sealing of the connection and preventing air leakage during vacuuming. Multiple fixing blocks 7 are fixedly connected to the outer wall of connecting ring 5. Each fixing block 7 has a sliding column 9 slidably connected inside it. Each of the moving columns 9 has a protruding column on its outer wall. The diameter of the protruding column is slightly larger than the diameter of the main body of the sliding column 9. Each of the multiple fixed blocks 7 has a left-right symmetrical limiting ball 8 inside. The limiting ball 8 engages with the groove inside the connecting ring 2 6. The protruding columns on the outer wall of the multiple sliding columns 9 are in contact with the outer wall of the limiting ball 8. When the sliding column 9 slides into the fixed block 7, the protruding column will squeeze the limiting ball 8, causing the limiting ball 8 to move outward and disengage from the groove of the connecting ring 2 6, making it easy to release the fixation. Each of the multiple sliding columns 9 has a recovery component on its outer wall. The lower mold 1 has a demolding component inside, making it easy for the user to take out the finished mold. Reference Figure 5 and Figure 6The demolding assembly includes a fixed plate 12 and a support plate 13. Both the fixed plate 12 and the support plate 13 are vertically placed plate structures, parallel to each other and spaced a certain distance apart. Their lower surfaces are fixedly connected to the bottom of the inner wall of the lower mold 1 by bolts. The lower surfaces of the fixed plate 12 and the support plate 13 are fixedly connected to the inner wall of the lower mold 1. A motor 14 is fixedly connected inside the fixed plate 12. A shaped block 15 is fixedly connected to the output end of the motor 14. The shaped block 15 has a conical structure. Its side away from the motor 14 is rotatably connected to a pre-set mounting hole inside the support plate 13 through a bearing, and can rotate stably around its own axis. The other side of the shaped block 15 is rotatably connected to the inside of the support plate 13. A transmission rod 16 is slidably connected to the outer wall of the shaped block 15. A connecting rod is fixedly connected to the top of the transmission rod 16. The connecting plate 17 is a horizontally placed circular structure. Multiple elastic columns 18 are uniformly fixedly connected to its upper surface along the circumference. The tops of the multiple elastic columns 18 all pass through the pre-set through holes at the bottom of the cavity of the lower mold 1 and are flush with the cavity surface. The elastic columns 18 can move up and down with the connecting plate 17 and lift the flange during demolding. Multiple elastic columns 18 are fixedly connected to the upper surface of the connecting plate 17. All the multiple elastic columns 18 are made of rubber. A second spring 19 is sleeved on the outer wall of the transmission rod 16. One end of the second spring 19 is fixedly connected to the lower surface of the connecting plate 17, and the other end is fixedly connected to the side wall of the transmission rod 16. The recovery component includes a first spring 10. The first spring 10 is sleeved on the outer wall of the sliding column 9. One end of the first spring 10 is fixedly connected to the inner wall of the fixing block 7, and the other end is fixedly connected to the side wall of the sliding column 9.

[0020] Working Principle: When using this vacuum adsorption mold to form FRP flanges, the raw material is first placed into the lower mold 1 by an operator. Then, the lower mold 1 and the upper mold 2 are closed, and the raw material is formed by vacuum adsorption. When connecting the lower mold 1 to the external vacuum equipment, the connecting pipe 4 is aligned with the vacuum interface 3 by an operator. Then, by pulling the sliding column 9, the sliding column 9 is driven to slide inside the fixed block 7, compressing the spring 10 to undergo elastic deformation and store elastic potential energy. Then, the connecting ring 5 and connecting ring 6 are attached to the connection between the vacuum interface 3 and the connecting pipe 4 by an operator. The sealing ring 11 ensures the sealing of the connection. By releasing the tension on the sliding column 9, Then, the elastic restoring force of spring 10 drives the sliding column 9 to reset, thereby squeezing the limiting ball 8 and driving the limiting ball 8 to be locked into the groove on the side wall of the connecting ring 2 6, thus achieving the effect of quickly connecting the vacuum interface 3 and the connecting pipe 4, providing convenience for the user. After molding is completed, the motor 14 can drive the irregular block 15 to rotate. When the irregular block 15 rotates, it will drive the transmission rod 16 to move up and down, thereby driving the elastic column 18 and spring 2 19 to move synchronously, realizing assisted demolding, making it easy for the user to take out the molded mold. At the same time as the connecting plate 17 and the elastic column 18 push out the mold, the spring 2 19 will provide elastic support to prevent rigid contact from damaging the mold.

[0021] 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.
