[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A centrifugal casting fiberglass elbow preparation device includes a rotating table with two sets of roller frames fixedly installed at both the front and rear ends of the top of the rotating table. A mold is mounted on the top of the roller frames. A heating cover is fixedly installed on the top of the rotating table and in the middle of the mold.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-7 This utility model provides a technical solution:

[0027] A centrifugal casting fiberglass elbow preparation device includes a rotary table 1. Two sets of roller frames 2 are fixedly installed at the front and rear ends of the top of the rotary table 1. A mold 3 is mounted on the top of the roller frames 2. A heating cover 4 is fixedly installed on the top of the rotary table 1 and in the middle of the mold 3. The mold 3 is rotatably connected to the heating cover 4. A forming cavity 5 is opened in the middle of the interior of the mold 3. A guide port 6 is opened at the front and rear ends of the forming cavity 5 inside the mold 3.

[0028] First, mold 3 consists of a first half mold 301 and a second half mold 302. Assembly modules 303 are fixedly connected to the upper and lower sides of both ends of the first half mold 301. Positioning blocks 304 are fixedly connected to both ends of the second half mold 302 at positions corresponding to the assembly modules 303. Locking pins 305 are slidably connected inside each assembly module 303, and the rear end of the locking pin 305 is inserted into the positioning block 304. A spring 306 is sleeved on the outside of the locking pin 305. A top ring 307 is fixedly connected to the outside of the locking pin 305 and at the rear end of the spring 306. A locking block 308 is fixedly connected to the outside of the top ring 307. A slot 309 is formed on the outside of the assembly module 303 at a position corresponding to the locking block 308. When the first half mold 301 and the second half mold 302 are assembled into mold 3... When the mold 3 is assembled, the positioning block 304 and the assembly module 303 are conveniently positioned. The locking pin 305 inside the assembly module 303 is inserted into the positioning block 304 under the action of the spring 306, realizing the quick positioning and connection of the first half mold 301 and the second half mold 302. When the mold 3 needs to be disassembled, the locking pin 305 is pulled and rotated to insert the locking block 308 into the locking position at the front end of the locking slot 309, thereby retracting the locking pin 305 into the interior of the assembly module 303 and fixing it, so that the locking pin 305 is moved out from the interior of the positioning block 304, allowing the first half mold 301 and the second half mold 302 to be opened for mold opening. Compared with the traditional fixing method of nuts and bolts, this structure makes mold closing and disassembly more convenient and faster, greatly improving production efficiency and reducing the time for mold 3 installation and disassembly.

[0029] Then, each of the four corners of the bottom of the rotary table 1 is equipped with a movable wheel 101. The bottom of the rotary table 1 and the outer side of the multiple sets of movable wheels 101 are threaded with fixed feet 102. The movable wheels 101 installed at the four corners of the bottom of the rotary table 1 can easily move the device. After the position is determined, the fixed feet 102 are rotated to make it contact the ground and fix it, preventing the device from shaking during operation. This facilitates the handling and installation of the device. The fixed feet 102 can ensure that the equipment is stable during operation and avoid the impact of equipment shaking on the casting process and product quality.

[0030] Furthermore, a limit frame 103 is fixedly installed at the rear end of the rotary table 1. An abutment wheel 104 is rotatably connected to the top of the limit frame 103. The limit frame 103 is fixed at the rear end of the rotary table 1, and the abutment wheel 104 is rotatably connected to it. When the mold 3 rotates, the abutment wheel 104 can play a certain abutment and limit role on the mold 3, preventing the mold 3 from shifting, enhancing the stability of the mold 3 during the rotation process, ensuring the smooth progress of the molding process, further improving the stability of product quality, and preventing deviations caused by the displacement of the mold 3 from affecting product molding.

[0031] In this configuration, rotating rollers 201 are rotatably connected to both ends of the inner side of multiple sets of roller frames 2. A transmission box 202 is fixedly installed on the outer side of one set of roller frames 2. A first transmission gear 203 is rotatably connected to the front end of the rotating roller 201 and inside the transmission box 202. A drive gear 204 is rotatably connected to the outer side of the roller frame 2 and inside the transmission box 202. A second transmission gear 205 is rotatably connected to the outer side of the roller frame 2 and between the drive gear 204 and the first transmission gear 203. The drive gear 204 and the first transmission gear 203 are also rotatably connected. All of them mesh with the second transmission gear 205. The drive motor 206 is fixedly installed inside the rotary table 1. The drive end of the drive motor 206 is connected to the drive gear 204 through the pulley set 207. The drive motor 206 drives the drive gear 204 through the pulley set 207, which in turn drives the second transmission gear 205 and the first transmission gear 203, ultimately causing the rotating roller 201 to rotate and drive the mold 3 to rotate. The stable rotation of the mold 3 allows the material to be evenly distributed on the inner wall of the mold 3 under the action of centrifugal force, ensuring the uniformity of the forming quality of the fiberglass elbow.

[0032] Secondly, the heating cover 4 consists of a fixed cover 401 and a top cover 402. The left and right sides of the fixed cover 401 are fixedly connected to the rotary table 1 through the support frame 403. The front and rear ends of the top of the support frame 403 are fixedly connected to the positioning posts 404, and multiple sets of positioning posts 404 are inserted into the left and right ends of the top cover 402. Multiple sets of heating coils 405 are fixedly installed inside the fixed cover 401 and the top cover 402. The heating cover 4 consists of a fixed cover 401 and a top cover 402. The fixed cover 401 is connected to the rotary table 1 through the support frame 403. The positioning posts 404 on the support frame 403 position the top cover 402. The heating coils 405 are distributed inside the fixed cover 401 and the top cover 402. When working, they generate heat and provide a suitable temperature for the mold 3 and its internal materials, promote the solidification and molding of the materials, and ensure that the fiberglass elbow products meet the required performance indicators.

[0033] Finally, the interior of the molding cavity 5 is equipped with a fiberglass elbow molding part 501. Both ends of the fiberglass elbow molding part 501 are fixedly connected with waste edges 502. During the centrifugal casting process, the mixture of glass fiber, resin, quartz sand and other materials prepared in proportion is poured into the molding cavity 5 through the feed port 6. In order to ensure that all parts of the molding cavity 5 are fully filled with materials, a slightly larger amount of glass fiber, resin, quartz sand and other materials than actually required will be poured in. Under the action of centrifugal force, the materials are thrown towards the inner wall of the molding cavity 5. During this process, due to the continuous action of centrifugal force and the structural characteristics of the mold 3, in addition to filling the main body of the fiberglass elbow molding part 501, some materials will adhere to and fill the areas at both ends of the fiberglass elbow molding part 501 that exceed the actual required size. This part of the excess area eventually forms the waste edges 502. The waste edges 502 can ensure the integrity of the molding part during the casting process, avoid the problem of uneven distribution of casting materials affecting the molding of key parts, facilitate later removal, and help ensure the final dimensional accuracy and quality of the fiberglass elbow.

[0034] In this embodiment, the specific implementation scenario is as follows: When the first half-mold 301 and the second half-mold 302 are assembled into mold 3, the positioning block 304 and the assembly module 303 facilitate positioning and assembly. The locking pin 305 in the assembly module 303 is inserted into the positioning block 304 under the action of the spring 306, realizing the rapid positioning and connection of the first half-mold 301 and the second half-mold 302. Subsequently, mold 3 is mounted on multiple sets of roller frames 2. The drive end of the drive motor 206 is connected to the drive gear 204 through the pulley set 207. The drive motor 206 drives the drive gear 204 through the pulley set 207, thereby driving the second transmission gear 205 and the first transmission gear 203. Finally, the rotating roller 201 rotates, driving the mold 3 to rotate. The mixture of glass fiber, resin, quartz sand, etc., prepared in proportion, is poured into the molding cavity 5 through the material guide port 6. The stable rotation of mold 3 allows the material to be evenly distributed on the inner wall of mold 3 under the action of centrifugal force, ensuring the uniformity of the molding quality of the fiberglass elbow. The fixed cover 40 1. The support frame 403 is connected to the rotary table 1. The positioning column 404 on the support frame 403 positions the top cover 402. The heating coil 405 is distributed inside the fixed cover 401 and the top cover 402. It generates heat during operation, providing a suitable temperature for the mold 3 and its internal materials, promoting the solidification and molding of the materials, and ensuring that the FRP elbow product meets the required performance indicators. After the FRP elbow molding part 501 is solidified and cooled in the molding cavity 5, the top cover 402 is opened and the mold 3 is disassembled and the material is removed. The locking column 305 is pulled and rotated to insert the locking block 308 into the locking position at the front end of the slot 309, thereby retracting the locking column 305 into the interior of the closing module 303 and fixing it, so that the locking column 305 is moved out from the interior of the positioning block 304, so that the first half mold 301 and the second half mold 302 can be opened for mold opening. The whole operation process is simple and convenient. Compared with the traditional nut and bolt fixing method, this structure makes mold closing and demolding more convenient and faster, greatly improving production efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
