Description

Technical Field

[0001] This utility model relates to the field of magnetic core processing equipment technology, and in particular to a ferrite magnetic core forming device. Background Technology

[0002] Ferrite cores are primarily composed of three metallic elements: iron, manganese, and zinc, and are commonly referred to as manganese-zinc ferrite. A wide range of ferrite cores are available, with different materials and shapes chosen based on varying magnetic parameters. Due to their low magnetic loss at high frequencies, they are widely used in switch-mode power supplies, RF transformers, and inductors.

[0003] In existing ferrite core manufacturing processes, material powder is typically placed into a mold and pressed to form the powder. However, in common core forming devices, the forming mold is often a single mold with fixed dimensions. When producing cores of other sizes, multiple mold structures need to be changed, and calibration is complex, making the operation very cumbersome and resulting in low production efficiency. Furthermore, due to the fine size of the magnetic powder particles, during the addition of magnetic powder and the closing and pressing of the upper and lower molds, the magnetic powder will splash and scatter onto the device table, causing table contamination and affecting the hygiene of the working environment. To solve the above problems, this utility model proposes a ferrite core forming device. Utility Model Content

One end of the screw is detachably connected to the lower pressing mold, and the other end passes through the support plate and protrudes on the other side of the support plate. A handle is provided at the end of the screw away from the lower pressing mold. A limiting sliding structure passes through the screw between the handle and the support plate. A fixing nut passes through the screw between the handle and the limiting sliding structure. An upper pressing mold is detachably connected to the top of the pressing table corresponding to the lower pressing mold.

[0007] Furthermore, the pressing table is equipped with support feet at all four corners of its bottom.

[0008] Furthermore, each of the dust-collecting structures has a dust-collecting port on the side facing the pressing platform, and a passage is provided on the bottom side of the pressing table corresponding to the dust-collecting structure. The dust-collecting structure is connected to an external dust-collecting device through the passage for blower suction.

[0009] Furthermore, the lower pressing mold has openings on both its upper and lower sides, and the size of the upper pressing mold matches the size of the opening on the upper side of the lower pressing mold.

[0010] Furthermore, the screw is provided with vertical sliding grooves on both support plates, and matching screw holes are provided on both sides of the pressing mold. The limiting sliding structure includes a fixing plate, and a limiting block is provided on the side of the fixing plate facing the support plate corresponding to the sliding groove. Multiple pulley structures are provided on the fixing plates on both sides of the limiting block, and through holes are provided on the fixing plate and the limiting block corresponding to the screw.

[0011] Furthermore, the size of the limiting block matches the size of the sliding groove, and the diameter of the through hole is larger than the diameter of the screw.

[0012] Furthermore, a matching threaded hole is provided in the fixing nut corresponding to the screw.

[0013] Furthermore, a hydraulic cylinder is connected to the top of the pressing mold, and the hydraulic cylinder and the pressing mold are connected by a detachable thread.

[0026] Please see Figures 1 to 5 As shown, a ferrite core forming device includes a pressing table 1, with support feet 101 at each of the four corners of the bottom of the pressing table 1, and a pressing platform 2 protruding from the top of the pressing table 1. Dust-collecting structures are provided on the four sides of the top of the pressing table 1 corresponding to the pressing platform 2, and each dust-collecting structure has a dust-collecting port 102 on the side facing the pressing platform 2. A through-hole 103 is provided on the bottom side of the pressing table 1 corresponding to the dust-collecting structure, and the dust-collecting structure is connected to an external dust-collecting device through the through-hole 103 for blower dust collection.

[0027] According to the above scheme, this utility model sets a dust collection structure on the four sides of the top of the pressing table 1 corresponding to the pressing platform 2. The dust collection structure surrounds the pressing table 1 and the pressing platform 2 to collect and recover the powder that is splashed and scattered on the pressing table 1 and the pressing platform 2, effectively ensuring the cleanliness and hygiene of the work surface of this molding device.

[0028] like Figure 2 The pressing platform 2 has two symmetrical support plates 201 on its top sides. A lower pressing mold 4 is detachably slidably connected between the two support plates 201. A higher pressing mold 3 is detachably connected to the top of the pressing table 1 corresponding to the lower pressing mold 4. The lower pressing mold 4 has openings on both its upper and lower sides. The size of the upper pressing mold 3 matches the size of the opening on the upper side of the lower pressing mold 4. A hydraulic cylinder is connected to the top of the upper pressing mold 3. The hydraulic cylinder and the upper pressing mold 3 are detachably threaded. The bottom of the thread of the hydraulic cylinder has a matching connecting thread hole on the top of the upper pressing mold 3.

[0029] like Figure 3 and Figure 4 The pressing mold 4 is detachably connected to screws 7 on both sides. One end of the screw 7 is detachably connected to the pressing mold 4, and the other end passes through the support plate 201 and protrudes on the other side of the support plate 201. Corresponding to the screw 7, there are vertical sliding grooves 2011 on both support plates 201. Corresponding to the screw 7, there are matching screw holes 401 on both sides of the pressing mold 4. The end of the screw 7 away from the pressing mold 4 is provided with a handle.

[0030] like Figure 5 A limiting sliding structure 5 is provided on the screw 7 between the handle and the support plate 201. The limiting sliding structure 5 includes a fixed plate 501. A limiting block 502 protrudes from the fixed plate 501 toward the support plate 201, corresponding to the sliding groove 2011. The size of the limiting block 502 matches the size of the sliding groove 2011. Multiple pulley structures 504 are provided on the fixed plates 501 on both sides of the limiting block 502.

[0031] A fixing nut 6 is provided on the screw 7 between the handle and the limiting sliding structure 5, and a matching threaded hole is provided in the fixing nut 6 corresponding to the screw 7.

[0032] According to the above scheme, the present invention installs a pressing mold 4 between two support plates 201 via a screw 7 in a detachable connection, and a pressing upper mold is installed at the bottom of the hydraulic cylinder in a detachable connection. This allows the pressing mold in the present invention to be flexibly replaced in terms of model and size through a threaded connection, making the present invention more widely applicable to the forming and processing of magnetic cores of various models and specifications.

[0033] Before use, the positions of the upper pressing mold 3 and the lower pressing mold 4 are calibrated. After calibration, the fixing nuts 6 on the screws 7 on both sides (tightened by turning them towards the side facing the lower pressing mold 4) are used to tightly fit and fix the two limiting sliding structures 5 to one side of the support plate 201, thereby limiting and fixing the position of the lower pressing mold 4. At the same time, the lower pressing mold 4 can also move vertically and flexibly between the two support plates 201 via the pulley structure 504 in the two limiting sliding structures 5.

[0034] When in use, the powder is poured into the lower pressing mold 4 and pressed and shaped by the vertical extrusion of the upper pressing mold 3. When demolding, the lower pressing mold 4 is slid upwards to quickly remove the formed magnetic core from the lower pressing mold 4. As the upper pressing mold 3 moves upwards and is recycled, the finished magnetic core can be quickly and efficiently removed from the device.
