Description

Technical Field

[0001] This application relates to casting equipment, and more particularly to an epoxy resin casting equipment for magnet processing. Background Technology

[0002] In the field of particle accelerator equipment manufacturing, magnets are core components, and their performance directly determines the accelerator's operating efficiency and stability. Epoxy resin casting is a key process to ensure the insulation, mechanical strength, and structural stability of magnets. By precisely mixing, casting, and curing epoxy resin and curing agent to form a sealed encapsulation structure, this process is widely used in key components of particle accelerators such as electromagnets of various pole types. Especially in high-end medical accelerators and other scenarios with stringent performance requirements, the casting quality directly affects the reliability and service life of the equipment.

[0003] The existing epoxy resin casting process for magnets has significant shortcomings. The mixing and degassing processes lack coordinated design. Traditional processes often use premixing followed by static degassing or casting in a single vacuum environment. This not only makes it difficult to achieve uniform mixing of high-viscosity resin and curing agent, but also results in residual bubbles due to the low degassing rate, which reduces the density of the magnet encapsulation.

[0004] To address the aforementioned issues, this application proposes an epoxy resin casting device for magnet processing. This device utilizes a dual-tank configuration with a metering pump to achieve precise raw material proportioning and independent transport. A spiral static mixer in the mixing and degassing assembly works in conjunction with a vacuum pump to achieve efficient mixing and deep degassing. A positioning component with vibration assists in degassing, and a precise temperature-controlled curing structure enables rapid and uniform curing. This significantly reduces the residual bubble rate, improves encapsulation density and production efficiency, and meets the performance requirements of high-end magnets. Utility Model Content

[0005] The purpose of this application is to provide an epoxy resin casting device for magnet processing, which has the advantages of high degassing rate and solves the problem of residual bubbles caused by low degassing rate.

[0006] The epoxy resin casting equipment for magnet processing provided in this application adopts the following technical solution: it includes two tanks, a mixing and degassing component and a positioning component. Support rods are provided on the surface of both tanks, and the same mixing and degassing component is provided at the opposite ends of the two support rods. The positioning component is located at the bottom of the mixing and degassing component.

[0007] By adopting the above technical solution, and by setting up two tanks, a mixing and degassing component and a positioning component, the tanks provide space for raw material storage, the support rods stably connect the tanks and the mixing and degassing component, and the positioning component provides support and fixation for the mold at the bottom. The overall structure is compact and works in concert, laying the foundation for accurate delivery, efficient mixing and degassing of raw materials, and ensuring the orderly connection of each process.

[0008] Preferably, the surfaces of the two tanks are provided with observation windows, the surfaces of the observation windows are provided with scales, the bottoms of the two tanks are provided with conduits, the surfaces of the conduits are provided with first metering pumps, the two conduits are fixedly inserted inside the mixing and degassing assembly, and the tops of the two sets of tanks are movably connected with cover plates via hinges.

[0009] By adopting the above technical solution, the observation window and scale on the surface of the tank make it easy to intuitively observe the remaining amount of raw materials inside and keep track of the raw material usage in real time. The first metering pump on the bottom conduit can accurately control the amount of raw materials delivered, ensuring that epoxy resin and curing agent are delivered in a preset ratio. The top cover can prevent external impurities from entering the tank, keep the raw materials clean, and improve the accuracy and purity of the raw material ratio.

[0010] Preferably, the mixing and degassing assembly includes a frame, the surface of which is wound with an ultrasonic transducer, a spiral static mixer is disposed inside the frame, a tube is disposed at the top of the frame, a vacuum pump is disposed on the surface of the tube, a delivery pipe is disposed at the bottom of the frame, and a second metering pump is disposed on the surface of the delivery pipe.

[0011] By adopting the above technical solution, in the mixing and degassing component, the ultrasonic transducer on the frame surface helps to break up the tiny air bubbles in the raw materials through high-frequency vibration, the internal spiral static mixer allows the epoxy resin and curing agent to fully blend in the flow, achieving uniform mixing, the vacuum pump evacuates the inside of the frame through the pipe, further removing the air bubbles generated during the mixing process and improving the degassing effect, and the second metering pump on the delivery pipe can accurately control the amount of raw materials poured after mixing, ensuring the stability and accuracy of the pouring process.

[0012] Preferably, the positioning component includes a base plate, the top of which has two sets of grooves, each set of grooves containing a lead screw, the surface of which is threaded with a threaded block, the top of which is a connecting rod, one end of which is an arc-shaped plate, the bottom of which is a wear-resistant pad, the arc-shaped plates containing soft pads, and drive motors on both sides of which are fixedly connected to the shaft end of the lead screw via a rotating shaft.

[0013] By adopting the above technical solution, in the positioning component, the drive motor drives the lead screw to rotate, causing the threaded block to move along the lead screw. Through the connecting rod, the arc plate moves closer to or away from the mold, realizing the stable clamping of molds of different specifications. The soft pad inside the arc plate can avoid damage to the mold during clamping, and the anti-wear pad at the bottom of the base plate reduces the friction between the equipment and the ground, ensuring the service life of the equipment.

[0014] Preferably, a mold is provided inside the two sets of arc-shaped plates, and the bottom of the mold is provided with a vent hole.

[0015] By adopting the above technical solution, the vent holes at the bottom of the mold can allow the tiny air bubbles remaining in the mold to be discharged through the vent holes, reducing the retention of air bubbles in the raw materials.

[0016] Preferably, both sides of the inner wall of the two sets of grooves are provided with sliding grooves, and a slider is slidably connected in the sliding grooves. The slider is fixedly connected to one side of the threaded block.

[0017] By adopting the above technical solution, the sliding groove on the inner wall of the groove and the slider on one side of the threaded block slide together, providing guidance for the movement of the threaded block, ensuring that the threaded block drives the arc plate to move smoothly, and avoiding the impact of shaking on the positioning accuracy of the mold.

[0018] Preferably, both sides of the base plate and the frame are provided with connecting plates, and electric push rods are provided in the two sets of connecting plates.

[0019] By adopting the above technical solution, the electric push rods in the connecting plates on both sides of the base plate and the frame can flexibly adjust the distance between the mixing and degassing component and the positioning component to adapt to the casting requirements of molds of different heights.

[0020] Preferably, each of the two sets of conduits is provided with an installation plate, and the inner walls of the two sets of conduits are fixedly connected with a ring body. A spring is provided on the top of the installation plate, and a plug is provided on the top of the spring. The plug is adapted to the ring body.

[0021] By adopting the above technical solution, the mounting plate, spring, plug and ring body inside the conduit cooperate with each other. When the raw material stops being transported, the spring pushes the plug and ring body to fit tightly, thereby sealing the conduit and preventing the raw material from flowing back, thus preventing backflow.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This epoxy resin casting equipment for magnet processing consists of two tanks, a mixing and degassing component, and a positioning component. The tanks provide space for raw material storage, support rods stably connect the tanks to the mixing and degassing component, and the positioning component provides support and fixation for the mold at the bottom. The overall structure is compact and works in synergy, laying the foundation for accurate delivery, efficient mixing, and degassing of raw materials, and ensuring the orderly connection of each process.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: An epoxy resin casting device for magnet processing, referring to... Figure 1 The system includes two tanks 1, a mixing and degassing component 2, and a positioning component 4. Each tank 1 has a support rod 5 on its surface, and the same mixing and degassing component 2 is located at the opposite ends of the two support rods 5. The positioning component 4 is located at the bottom of the mixing and degassing component 2. By setting up two tanks 1, a mixing and degassing component 2, and a positioning component 4, the tanks 1 provide space for raw material storage, the support rods 5 stably connect the tanks 1 and the mixing and degassing component 2, and the positioning component 4 provides support and fixation for the mold 412 at the bottom. The overall structure is compact and works in concert, laying the foundation for accurate delivery, efficient mixing, and degassing of raw materials, and ensuring the orderly connection of each process.

[0027] Example 2: An epoxy resin casting device for magnet processing (reference) Figure 1 , Figure 2 and Figure 3Two tanks 1 have observation windows 102 on their surfaces, with scales 101 on their surfaces. Each tank 1 has a conduit 104 at its bottom, with a first metering pump 105 on its surface. Both conduits 104 are fixedly inserted into the mixing and degassing assembly 2. Both tanks 1 are hinged to a cover 103 at their tops. The observation windows 102 and scales 101 on the tank 1 surface allow for direct observation of the remaining material level and real-time monitoring of material usage. The first metering pump 105 on the bottom conduit 104 precisely controls the material delivery rate, ensuring that epoxy resin and curing agent are delivered in a preset ratio. The top cover 103 prevents external impurities from entering the tank 1, maintaining material cleanliness and improving the accuracy and purity of the material ratio. The mixing and degassing assembly 2 includes a frame 202, with ultrasonic transducers 3 wound around its surface. A spiral mechanism is installed inside the frame 202. The static mixer 201 has a frame 202 with a tube 204 at the top and a vacuum pump 203 on the surface of the tube 204. A conveying pipe 9 is located at the bottom of the frame 202, and a second metering pump 8 is installed on the surface of the conveying pipe 9. In the mixing and degassing assembly 2, the ultrasonic transducer 3 on the surface of the frame 202 assists in breaking down tiny air bubbles in the raw materials through high-frequency vibration. The internal spiral static mixer 201 ensures that the epoxy resin and curing agent are fully integrated during flow, achieving uniform mixing. The vacuum pump 203 evacuates the interior of the frame 202 through the tube 204, further removing air bubbles generated during mixing and improving the degassing effect. The second metering pump 8 on the conveying pipe 9 precisely controls the pouring volume of the mixed raw materials, ensuring the stability and accuracy of the pouring process. The positioning assembly 4 includes a base plate 401 with two sets of grooves 404 on the top, each containing a lead screw 408. The surface of the lead screw 408 is threaded with threaded blocks 407. Each set of threaded blocks 407 has a connecting rod 409 on its top. Each set of connecting rods 409 has an arc plate 411 at one end. The bottom of the base plate 401 has an anti-wear pad 410. Each set of arc plates 411 has a soft pad 402 inside. Both sides of the base plate 401 have a drive motor 403. The other end of the output shaft of the drive motor 403 is fixedly connected to the shaft end of the lead screw 408 through a rotating shaft. In the positioning assembly 4, the drive motor 403 drives the lead screw 408 to rotate, causing the threaded blocks 407 to move along the lead screw 408. Through the connecting rods 409, the arc plates 411 move closer to or away from the mold 412, achieving stable clamping of molds 412 of different specifications. The soft pad 402 inside the arc plates 411 can prevent damage to the mold 412 during clamping. The anti-wear pad 410 at the bottom of the base plate 401 reduces friction between the equipment and the ground, ensuring the service life of the equipment.

[0028] Example 3: An epoxy resin casting device for magnet processing (reference) Figure 1 , Figure 4 and Figure 5Two sets of arc-shaped plates 411 each contain a mold 412. The bottom of each mold 412 has a vent 413. The vent 413 allows residual micro-air bubbles to escape, reducing their retention in the raw material. Both sides of the inner walls of the two sets of grooves 404 have sliding grooves 405. A slider 406 is slidably connected within each groove 405. The slider 406 is fixedly connected to one side of the threaded block 407. The sliding grooves 405 on the inner walls of the grooves 404 and the slider 406 on one side of the threaded block 407 provide guidance for the movement of the threaded block 407, ensuring smooth movement of the arc-shaped plates 411 and preventing shaking that could affect the positioning accuracy of the mold 412. Connecting plates 6 are provided on both sides of the base plate 401 and the frame 202. Electric push rods 7 are installed within the two sets of connecting plates 6. The base plate 401 and the frame... The electric push rods 7 inside the connecting plates 6 on both sides of the frame 202 can flexibly adjust the distance between the mixing and degassing component 2 and the positioning component 4 to adapt to the casting requirements of molds 412 of different heights. Each of the two sets of conduits 104 is equipped with an installation plate 106. The inner walls of the two sets of conduits 104 are fixedly connected with rings 109. A spring 107 is installed on the top of the installation plate 106, and a plug 108 is installed on the top of the spring 107. The plug 108 is adapted to the ring 109. The installation plate 106, spring 107, plug 108 and ring 109 in the conduit 104 cooperate. When the raw material stops being conveyed, the spring 107 pushes the plug 108 to fit tightly with the ring 109, thereby sealing the conduit 104 and preventing the raw material from flowing back, thus preventing backflow.

[0029] The implementation principle of this application embodiment is as follows: When using the epoxy resin casting equipment for magnet processing, epoxy resin and curing agent are added to the tank 1 respectively. The remaining amount of raw materials is confirmed through the observation window 102 on the surface of the tank 1 in conjunction with the scale 101. After the addition is completed, the cover plate 103 is tightened, the magnet to be cast is placed into the mold 412, and the mold 412 is positioned. The mold 412 containing the magnet is placed on the base plate 401 of the positioning component 4. The drive motors 403 on both sides of the base plate 401 are started. The output shaft of the motor drives the lead screw 408 in the groove 404 to rotate, and the threaded block 407 rotates. The lead screw 408 moves under the action of the threaded surface, while the slider 406 on one side of the threaded block 407 slides along the groove 405 on the inner wall of the groove 404, providing guidance for the movement of the threaded block 407 and ensuring its smooth movement. The threaded block 407 drives the arc plate 411 to gradually approach the mold 412 through the connecting rod 409, until the soft pad 402 in the arc plate 411 is tightly attached to the outer wall of the mold 412, realizing a stable clamping of the mold 412. The pouring position is adjusted according to the height of the mold 412. The mixing and dewatering are adjusted by the electric push rods 7 in the connecting plates 6 on both sides of the base plate 401 and the frame 202. The distance between the bubble assembly 2 and the positioning assembly 4 is adjusted so that the conveying pipe 9 at the bottom of the mixing and degassing assembly 2 is aligned with the pouring port of the mold 412, facilitating precise subsequent pouring. The raw material conveying and mixing / degassing process is initiated: the first metering pump 105 on the bottom conduit 104 of the two tanks 1 is turned on. Under pump pressure, the raw material pushes the plug 108 inside the conduit 104. The compression spring 107 causes the plug 108 to disengage from the ring 109. Epoxy resin and curing agent enter the frame 202 of the mixing and degassing assembly 2 through the conduit 104 in a preset ratio. The spiral static mixer 201 inside the frame 202... The two raw materials are fully fused during the flow to achieve uniform mixing. At the same time, the ultrasonic transducer 3 wrapped around the surface of the frame 202 vibrates at high frequency to break up the tiny air bubbles in the raw materials. In conjunction with the top vacuum pump 203, the frame 202 is evacuated through the pipe 204 to further remove the air bubbles generated during the mixing process and improve the degassing effect. After the mixing and degassing are completed, the second metering pump 8 on the conveying pipe 9 is started to accurately convey the processed mixed raw materials into the mold 412 through the conveying pipe 9. During the casting process, the vent hole 413 at the bottom of the mold 412 can help to remove the tiny air bubbles remaining in the raw materials.
