Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, and in particular to a multi-U-core molding die. Background Technology

[0002] In the field of inductor manufacturing, multi-U-core molding dies are key equipment for producing multi-U-core components. A multi-U-core is a magnetic element composed of multiple U-shaped structures and is widely used in various inductors. Through specific structures and processes, multi-U-core molding dies process raw materials such as magnetic powder into U-core components with precise shapes and dimensions. These U-core components are then assembled into inductors in subsequent processes to enhance the electromagnetic performance of the inductors, achieve a more compact size and higher power density, and meet the ever-increasing demands of electronic devices for inductor performance.

[0003] A search revealed that publication number CN219040242U provides an inductor forming mold, relating to the field of inductor processing technology. The mold includes: a mold body with a forming groove on its upper surface, threaded holes at the corners of the upper surface, and a slot near the front surface; and a demolding assembly comprising a first baffle, a U-shaped plate fixedly connected to the outer surface of the first baffle, and a second baffle fixedly connected to the outer surface of the U-shaped plate. In this invention, by setting up the demolding assembly, after the inductor is hot-pressed and formed, once the U-shaped plate is removed, a groove exists in the inductor at the U-shaped plate position during hot-pressing in the forming groove. Therefore, the inductor can be removed from the forming groove simply by pressing the groove, making the demolding operation convenient and quick, thus improving work efficiency.

[0004] In current multi-U-core molding dies, the lack of an effective unloading and residue cleaning mechanism results in slow unloading speed, leading to low production efficiency and the generation of residue during stamping, which affects the quality of subsequent products. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-U-core molding die, which aims to improve the problem of existing molding molds lacking unloading and residue cleaning mechanisms, thus affecting production efficiency and product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-U-core molding die, including a fixed platform, a plurality of bases fixedly connected to the surface of the fixed platform, a motor fixedly connected to the surface of the fixed platform, a threaded rod fixedly provided at the output end of the motor, a push plate threadedly connected to the surface of the threaded rod, a plurality of first sliding rods fixedly connected to the top of each of the plurality of bases, a fixed plate slidably connected between the plurality of first sliding rods, and a connecting component provided on the surface of the fixed plate.

[0007] The above technical solution enables the motor to drive the threaded rod to rotate after stamping, which in turn drives the push plate to slide, pushing the stamped powder base block and debris on the fixed platform to the connecting platform. This allows for simultaneous unloading and cleaning, greatly improving production efficiency and reducing unloading and cleaning time and labor intensity.

[0008] As a further description of the above technical solution:

[0009] The connecting assembly includes a connector, which is fixedly connected to a fixing plate. A second slide rod is fixedly connected to the inner wall of the connector. A locking member is slidably connected to the surface of the second slide rod. A fixing block is fixedly connected to the surface of the locking member. A second spring is fixedly connected to the surface of the locking member. The second spring is fixedly connected to the connector.

[0010] The above technical solution enables users to push the fixing block when the punch needs to be replaced, causing the locking part to slide on the second slide bar, squeezing the second spring to move upward until it is disengaged from the limiting groove. At this time, the mounting part can be slid backward and removed, thereby replacing the internal punch and shortening the punch replacement time.

[0011] As a further description of the above technical solution:

[0012] The connector is slidably connected to an mounting component, and the mounting component has a groove on its top.

[0013] The above technical solution enables the mounting part to be slid back and removed when the punch needs to be replaced, thereby facilitating the disassembly and replacement of the punch inside the mounting part and improving the convenience of mold maintenance.

[0014] As a further description of the above technical solution:

[0015] The mounting component has multiple punches that slide inside, and a limit groove is formed on the top of the mounting component.

[0016] The above technical solution enables easy disassembly and replacement of worn punches. When a punch is worn or damaged, it is not necessary to replace the entire mounting component, thus reducing maintenance costs.

[0017] As a further description of the above technical solution:

[0018] Multiple first springs are fixedly connected to the surfaces of the multiple bases, and the tops of the multiple first springs are fixedly connected to the fixing plate.

[0019] The above technical solution achieves the following: after the pressing mechanism drives the fixed plate and punch to move downward to complete the pressing, the first spring will generate an upward elastic force to lift the fixed plate and raise the punch, making it easier to remove the pressed powder base block for the next pressing operation.

[0020] As a further description of the above technical solution:

[0021] The surface of the fixing plate is fixedly connected with a connector.

[0022] The above technical solution enables the bottom fixing plate and punch to move downwards when the top pressing mechanism presses down on the connector, until the powder base block is squeezed to achieve the stamping operation, thus ensuring the smooth progress of the stamping action.

[0023] As a further description of the above technical solution:

[0024] A connecting platform is fixedly connected to the surface of the fixed platform, and a powder base block is provided on the top of the fixed platform.

[0025] The above technical solution enables the pusher plate to push the stamped powder base block and the debris on the fixed table to the connecting table after stamping, so as to facilitate subsequent centralized processing. The punch applies pressure to the powder base block and stamps out multiple cavities on the powder base block. After subsequent processing, the required shape and structure of the multi-U-core are formed.

[0026] As a further description of the above technical solution:

[0027] A third sliding rod is fixedly connected to the inner wall of the fixed platform, and the third sliding rod is slidably connected to the push plate.

[0028] The above technical solution involves a third slide rod that is slidably connected to the push plate, providing guidance for the movement of the push plate and preventing it from deviating during movement.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, after the top punch is completed, the threaded rod is rotated by the motor, thereby driving the push plate to slide on the third slide rod. The push plate moves forward to push the completed powder base block and the debris obtained on the fixed table to the front connecting table, so as to quickly unload the completed powder base block and clean the debris, and prevent the untimely unloading and cleaning from affecting the stamping efficiency.

[0031] 2. In this utility model, by pushing the fixing block, the locking part is moved. The locking part squeezes the second spring and slides on the second slide rod. At this time, the locking part is disengaged from the limiting groove. The mounting part can be removed by sliding the mounting part backward. Then the internal punch can be disassembled and replaced, which shortens the punch replacement time, makes mold maintenance more efficient, and reduces equipment downtime.

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0039] Reference Figures 1-3An embodiment of this utility model is provided: a multi-U-core molding die, including a fixed platform 1, a plurality of bases 2 fixedly connected to the surface of the fixed platform 1, a motor 13 fixedly connected to the surface of the fixed platform 1, a threaded rod 14 fixedly provided at the output end of the motor 13, a push plate 12 threadedly connected to the surface of the threaded rod 14, a plurality of first sliding rods 4 fixedly connected to the top of each of the plurality of bases 2, a fixed plate 6 slidably connected between the plurality of first sliding rods 4, and a connecting component 8 provided on the surface of the fixed plate 6;

[0040] Specifically, after stamping is completed, the motor 13 starts and drives the threaded rod 14 to rotate, causing the push plate 12 to slide on the third slide rod 15, pushing the stamped powder base block 11 and debris on the fixed table 1 towards the connecting table 3 to complete the unloading and cleaning work, thereby improving production efficiency.

[0041] Reference Figures 3-4 The connecting component 8 includes a connector 805, which is fixedly connected to the fixing plate 6. A second slide rod 801 is fixedly connected to the inner wall of the connector 805. A locking component 803 is slidably connected to the surface of the second slide rod 801. A fixing block 804 is fixedly connected to the surface of the locking component 803. A second spring 802 is fixedly connected to the surface of the locking component 803. The second spring 802 is fixedly connected to the connector 805.

[0042] Specifically, when the punch 10 needs to be replaced, the user pushes the fixing block 804 to drive the locking part 803 to slide on the second slide bar 801. The locking part 803 moves upward to squeeze the second spring 802 until the locking part 803 disengages from the limiting groove 17. At this time, the user slides the mounting part 9 backward to remove the mounting part 9, and then the internal punch 10 can be slid upward to be taken out for replacement, which shortens the punch 10 replacement time, makes mold maintenance more efficient, and reduces equipment downtime.

[0043] Reference Figures 3-4 The surface of the connector 805 is slidably connected to the mounting part 9, and the top of the mounting part 9 is provided with a groove 16;

[0044] Specifically, the mounting part 9 can move relative to the connecting part 805 to facilitate sliding the mounting part 9 backward and removing it, thereby facilitating the disassembly and replacement of the punch 10 inside the mounting part 9, improving the convenience of mold maintenance. The slide groove 16 provides a track for disassembling and installing the mounting part 9 to prevent deviation in the installation position.

[0045] Reference Figures 3-4 The mounting component 9 has multiple punches 10 that slide inside, and a limit groove 17 is provided on the top of the mounting component 9;

[0046] Specifically, during the stamping operation, the punch 10 can move up and down according to the mold operation requirements to complete the stamping and forming operation of the powder material, realize the production of multiple U-cores, and facilitate the individual disassembly and replacement of the punch 10. When a certain punch 10 is worn or damaged, there is no need to replace the entire mounting part 9, reducing maintenance costs.

[0047] Reference Figure 1 Multiple bases 2 are fixedly connected to multiple first springs 5, and the tops of multiple first springs 5 ​​are fixedly connected to the fixing plate 6.

[0048] Specifically, after stamping, multiple first springs 5 ​​lift the top fixing plate 6, causing the punch 10 to rise. At this time, the powder base block 11 can be removed for the next stamping operation.

[0049] Reference Figure 1 The surface of the fixing plate 6 is fixedly connected with the connector 7;

[0050] Specifically, when the top pressing mechanism presses down on the connector 7, it drives the bottom fixing plate 6 and punch 10 to move downward until the powder base block 11 is extruded to achieve the stamping operation.

[0051] Reference Figure 1 A connecting platform 3 is fixedly connected to the surface of the fixed platform 1, and a powder base block 11 is provided on the top of the fixed platform 1;

[0052] Specifically, the powder base block 11 is the basic raw material carrier for multi-U-core molding, providing the processing object for the punch 10. When the punch 10 applies pressure to the powder base block 11, it punches out multiple cavities on the powder base block 11 through its specific shape and structure. These cavities, after subsequent processing, can form the shape and structure required for multi-U-core.

[0053] Reference Figure 2 A third slide rod 15 is fixedly connected to the inner wall of the fixed platform 1, and the third slide rod 15 is slidably connected to the push plate 12;

[0054] Specifically, the third slide bar 15 provides a stable sliding guide for the push plate 12, enabling the push plate 12 to reciprocate linearly along the direction of the third slide bar 15 within the fixed platform 1, thus ensuring the accuracy and stability of the push plate 12's movement.

[0055] Working principle: The user first places the powder base block 11 on the top of the fixed table 1. Then, the top pressing mechanism presses down on the connector 7, which drives the fixed plate 6 to slide between the first slide rod 4. At this time, the punch 10 moves downward and squeezes the powder base block 11, punching multiple cavities on its surface to complete the forming of the multi-U-core. After the stamping is completed, the first spring 5 lifts the fixed plate 6 to raise the punch 10. The user starts the motor 13, which drives the threaded rod 14 to rotate. The push plate 12 slides on the third slide rod 15, pushing the formed multi-U-core and debris to the connecting table 3 to complete the unloading and cleaning.

[0056] When the punch 10 needs to be replaced, the user pushes the fixing block 804, causing the locking part 803 to slide on the second slide bar 801, squeezing the second spring 802, causing the locking part 803 to disengage from the limiting groove 17, and then slides the mounting part 9 backward to slide the worn or damaged punch 10 upward for replacement. Throughout the process, all components work together to achieve efficient molding of multi-U-core and convenient mold maintenance.

[0057] 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.
