Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a high-efficiency magnetic core mold. Background Technology

[0002] Powder cores are produced by filling a molding mold with granulated powder containing soft magnetic powder and insulating binder material, and then compressing the granulated powder in the mold to form a shaped body with a certain shape.

[0003] The prior art discloses a molding and pressing device for magnetic core production, with application number CN202420888377.4. This device facilitates the smoothing of powder in the mold cavity while feeding, avoiding uneven pressing in the later stages and preventing excess powder from adhering to the mold opening. It can quickly install and disassemble the molding mold. However, the device lacks continuity in operation, making it inconvenient to completely and continuously integrate molding, filling, and demolding. There are often gaps in operation, and these gaps are relatively long. For example, the mold is relatively stationary during filling and demolding, resulting in low mold working efficiency and limited practicality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-efficiency magnetic core mold to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency magnetic core mold, comprising a base, a mounting frame on the top of the base, a hydraulic rod and a storage trough on the top of the mounting frame, an output end of the hydraulic rod connected to a mounting plate, an upper module mounted on the bottom of the mounting plate, a toothed rod fixed on one side of the mounting plate, a connecting cylinder connected to the bottom of the storage trough via a feeding pipe, and a discharge pipe connected to the bottom of the connecting cylinder, a feeding roller mounted inside the connecting cylinder via a rotating shaft, a rotating gear fixed at one end of the rotating shaft, a motor mounted in the middle of the base, and a turntable connected to the output end of the motor, four sets of lower mold slots on the top of the turntable, a toothed ring on the outer surface of the turntable, a top frame penetrating the bottom of the turntable, a spring mounted on the inner side of the top frame, a top plate fixed on the top of the top frame, a movable protrusion fixed on the bottom of the top frame, a fixed protrusion fixed on one side of the top of the base, and a connecting shaft mounted on the other side of the top of the base, the outer surface of the connecting shaft being provided with a scraper plate and a transmission gear.

[0006] Furthermore, a control panel is installed on the top side of the mounting bracket, and the hydraulic rod and motor are both electrically connected to the control panel.

[0007] By adopting the above technical solution, staff can control the hydraulic rods and motors through the control panel.

[0008] Furthermore, the scraper plate is provided in multiple sets, and the bottom of the scraper plate is in contact with the top of the turntable.

[0009] By adopting the above technical solution, the scraper can flatten the powder when it rotates, thus ensuring the pressing effect.

[0010] Furthermore, the rack meshes with the transmission gear, and the ring gear meshes with the rotating gear.

[0011] By adopting the above technical solution, the movement of the rack can drive the transmission gear to rotate, and the rotation of the gear ring can drive the rotating gear to rotate.

[0012] Furthermore, a collection groove is installed on one side of the inside of the base, and a handle is fixed on the outer surface of the collection groove, and the collection groove is detachably connected to the base.

[0013] By adopting the above technical solution, the collection tank can collect some of the excess powder, and the handle makes it easy to pull the collection tank out of the base.

[0014] Furthermore, the bottom of the turntable is fixed with several sets of support columns, and the bottom of each set of support columns is inlaid with ball bearings.

[0015] By adopting the above technical solution, the turntable can be made more stable under pressure by the support column, and the ball bearings reduce the friction between the support column and the turntable.

[0016] Furthermore, both the movable protrusion and the fixed protrusion are hemispherical.

[0017] By adopting the above technical solution, the hemispherical design enables the fixed protrusion to squeeze the movable protrusion more smoothly.

[0018] Furthermore, the outer surface of the feeding roller is provided with a groove, and the volume of the groove is equal to the volume of the lower mold groove. The outer surface of the feeding roller is in contact with the inner wall of the connecting cylinder.

[0019] By adopting the above technical solution, the powder first falls into the groove for temporary storage. When the feeding roller flips, the powder in the groove falls into the lower mold groove and just fills the lower mold groove. The close contact between the feeding roller and the connecting cylinder can prevent the powder from falling out of the gap.

[0020] Furthermore, the lower interior of the storage tank is inclined along the direction of the discharge pipe.

[0021] By adopting the above technical solution, the inclined setting plays a guiding role, allowing the powder to flow smoothly from the direction of the feed pipe.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model comprises a toothed rod, four sets of lower mold slots, a rotating shaft, a rotating gear, a storage tank, a feeding roller, a feeding pipe, and a discharge pipe. First, the operator manually adds powder to the lower mold slot located directly below the upper module. Then, the hydraulic rod is activated, pushing the mounting plate downwards. The downward movement of the mounting plate causes the upper module and the toothed rod to shift downwards, pressing the powder in the lower mold slot to form an inverted "E"-shaped magnetic core. When the toothed rod shifts downwards, the rotating gear rotates, which in turn causes the rotating shaft to rotate the feeding roller 180°. The powder in the feeding roller is then filled into the next set of lower mold slots through the discharge pipe for pressing. After the magnetic core in the first lower mold slot is pressed, the hydraulic rod moves the mounting plate upwards, and the toothed rod drives the rotating gear to rotate in the opposite direction to reset. This causes the groove on the feeding slot to face upwards, and the powder in the storage tank re-enters the groove for the next feeding. In this way, the amount of powder fed each time is approximately equal, eliminating the need for manual filling and reducing the labor intensity of the operators.

[0024] 2. This utility model includes a motor, a gear ring, a transmission gear, a connecting shaft, a collection groove, and a scraper plate. After the magnetic core in the first lower mold groove is pressed, the motor rotates, causing the turntable to rotate. The turntable rotates, causing the gear ring to rotate. The gear ring drives the connecting shaft to rotate through the transmission gear, thereby causing the scraper plate to rotate. Meanwhile, the second lower mold groove rotates towards the upper module. The scraper plate can scrape the powder evenly, ensuring that the powder in the lower mold groove is evenly distributed, thus ensuring the quality of the magnetic cores pressed later. Any excess powder is scraped off into the collection groove for collection, avoiding powder waste.

[0025] 3. This utility model is equipped with a top frame, a top plate, a spring, a fixed protrusion, and a movable protrusion. When the first lower mold groove rotates towards the fixed protrusion, the movable protrusion contacts and squeezes the fixed protrusion, thereby causing the spring to contract. The top frame drives the top plate to move upward, and the top plate lifts the magnetic core in the first lower mold groove, completing the demolding operation. At this time, the second lower mold groove is located directly below the upper module and is ready to be pressed. Through the cooperation of the above structures, the device has a high degree of automation. The operator only needs to remove the ejected magnetic core, which has strong continuity and high work efficiency. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1: A high-efficiency magnetic core mold, such as Figures 1-4As shown, the device includes a base 1, with a mounting bracket 2 on top. The mounting bracket 2 has a hydraulic rod 4 and a storage tank 5 on its top. The output end of the hydraulic rod 4 is connected to a mounting plate 9, and an upper module 10 is mounted on the bottom of the mounting plate 9. A toothed rod 20 is fixed to one side of the mounting plate 9. The bottom of the storage tank 5 is connected to a connecting cylinder 7 via a discharge pipe 6. The lower interior of the storage tank 5 is inclined along the direction of the discharge pipe 6, which serves as a guide, allowing the powder to flow smoothly from the discharge pipe. The material flows in the direction of the feeding pipe 6, and the bottom of the connecting cylinder 7 is connected to the discharge pipe 8. A feeding roller 29 is installed inside the connecting cylinder 7 via a rotating shaft 21. A rotating gear 22 is fixed to one end of the rotating shaft 21. A motor 18 is installed in the middle of the base 1, and the output end of the motor 18 is connected to a turntable 11. The top of the turntable 11 has four sets of lower mold grooves 12. The outer surface of the feeding roller 29 has grooves, and the volume of the grooves is equal to the volume of the lower mold grooves 12. The outer surface of the feed roller 29 contacts the inner wall of the connecting cylinder 7. The powder first falls into the groove for temporary storage. When the feed roller 29 rotates, the powder in the groove falls into the lower mold groove 12, just filling the lower mold groove 12. The close contact between the feed roller 29 and the connecting cylinder 7 can prevent the powder from falling out of the gap. The outer surface of the turntable 11 is provided with a toothed ring 13. The bottom of the turntable 11 is penetrated by a top frame 25. A spring 28 is installed on the inner side of the top frame 25, and a top plate 27 is fixed to the top of the top frame 25. The bottom of the base 1 is fixed with a movable protrusion 26, and the top side of the base 1 is fixed with a fixed protrusion 19. The other side of the top of the base 1 is equipped with a connecting shaft 15. The outer surface of the connecting shaft 15 is respectively provided with a scraper plate 17 and a transmission gear 16. The inner side of the base 1 is equipped with a collection groove 14. The outer surface of the collection groove 14 is fixed with a handle. The collection groove 14 is detached from the base 1. The collection groove 14 can collect some excess powder. The handle makes it easy to pull the collection groove 14 out of the base 1.

[0034] See Figure 1 In the above embodiment, a control panel 3 is installed on the top side of the mounting bracket 2, and the hydraulic rod 4 and the motor 18 are electrically connected to the control panel 3. The operator can control the hydraulic rod 4 and the motor 18 through the control panel 3.

[0035] See Figures 1-3 In the above embodiment, the scraper plate 17 is provided in multiple sets, and the bottom of the scraper plate 17 is in contact with the top of the turntable 11. When the scraper plate rotates, it can scrape the powder flat, thus ensuring the pressing effect.

[0036] See Figures 1-3In the above embodiment, the rack 20 meshes with the transmission gear 16, and the gear ring 13 meshes with the rotating gear 22. When the rack 20 moves, it can drive the transmission gear 16 to rotate, and the rotation of the gear ring 13 can drive the rotating gear 22 to rotate.

[0037] See Figures 1-4 In the above embodiment, both the movable protrusion 26 and the fixed protrusion 19 are hemispherical. The hemispherical design makes it easier for the fixed protrusion 19 to squeeze the movable protrusion 26.

[0038] Example 2: To increase the stability of the turntable and prevent it from tilting under pressure, Example 2 is an improvement on Example 1. (See attached document.) Figures 1-3 The bottom of the turntable 11 is fixed with several sets of support columns 23, and the bottom of each set of support columns 23 is inlaid with ball bearings 24. Under the action of the support columns 23, the turntable 11 can be more stable when it is under pressure, and the ball bearings 24 reduce the friction between the support columns 23 and the turntable 11.

[0039] The implementation principle of this utility model is as follows: First, the operator manually adds powder to the lower mold groove 12 located directly below the upper module 10. Then, the hydraulic rod 4 is activated, which pushes the mounting plate 9 downward. The downward movement of the mounting plate 9 causes the upper module 10 and the gear 20 to move downward. The upper module 10 presses the powder in the lower mold groove 12 to form an inverted "E" shaped magnetic core. When the gear 20 moves downward, it causes the rotating gear 22 to rotate, which in turn causes the rotating shaft 21 to drive the feeding roller 29 to rotate 180°. The powder in the feeding roller 29 is then filled into the next set of lower mold grooves 12 through the discharge pipe 8 to be pressed. After the magnetic core in the first lower mold groove 12 is pressed, the hydraulic rod 4 drives the mounting plate 9 to move upward, and the gear 20 drives the rotating gear 22 to rotate in the opposite direction to reset, so that the groove on the feeding groove faces upward. The powder in the storage tank 5 re-enters the groove to await the next feeding. When the first lower mold groove 12 is pressed, the upper module 10 presses the powder in the storage tank 5 to be pressed into the groove. After the inner magnetic core is pressed, the motor 18 rotates, causing the turntable 11 to rotate. The rotation of the turntable 11 causes the gear ring to rotate, which in turn drives the connecting shaft 15 to rotate via the transmission gear 16. This causes the scraper plate 17 to rotate, and the second lower mold groove 12 rotates towards the upper module 10. The scraper plate 17 can scrape the powder evenly, ensuring that the powder in the lower mold groove 12 is evenly distributed and ensuring the quality of the magnetic cores pressed later. Any excess powder is scraped off and collected in the collection trough 14. When the first lower mold groove 12 rotates towards the fixed protrusion 19, the movable protrusion 26 contacts and squeezes the fixed protrusion 19, causing the spring 28 to contract. The top frame 25 drives the top plate 27 to move upward, and the top plate 27 lifts the magnetic core in the first lower mold groove 12, completing the demolding operation. At this time, the second lower mold groove 12 is located directly below the upper module 10 and is ready to be pressed. The operator can then remove the ejected magnetic core.
