[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Please refer to Figures 1-6 The embodiment provides a technical scheme: a magnetic core processing and pressing die, comprising an upper die 1, a lower die 2 and a demolding mechanism 8.

[0026] The upper die 1 is placed with the lower die 2 on the lower side, the upper surface of the upper die 1 is fixedly connected with the mounting plate 7 at four corners, the middle part of the lower surface of the upper die 1 and the middle part of the upper surface of the lower die 2 are respectively provided with the avoiding groove 4, the upper side wall of the upper avoiding groove 4 is provided with the top wedge-shaped die groove 5, the lower side wall of the lower avoiding groove 4 is provided with the bottom wedge-shaped die groove 10, the four corners of the lower surface of the upper die 1 and the four corners of the upper surface of the lower die 2 are respectively provided with the butt joint groove 3, the four corners of the lower surface of the upper die 1 and the four corners of the upper surface of the lower die 2 are respectively provided with the limiting hole 6, the upper surface of the upper die 1 is fixedly connected with the hydraulic rod connecting seat 9, when the pressing die needs to be used, the lower die 2 is installed to the specified work station, then the external limiting rod is sequentially inserted into the plurality of limiting holes 6, and the hydraulic rod connecting seat 9 and the telescopic end of the external hydraulic rod are fixed.

[0027] The demolding mechanism 8 comprises a demolding frame 81, a connecting cylinder 82, a rectangular slide column 83, a wedge-shaped butt joint mold plate 84 and a telescopic rod 86. The telescopic rod 86 is fixedly connected to the lower surface of the four mounting plates 7 respectively, the lower end of the four telescopic rods 86 is fixedly connected to the upper surface of one demolding frame 81, the inner wall of the demolding frame 81 is fixedly connected with uniformly distributed connecting cylinders 82 (the inner wall of the demolding frame 81 is downwardly inclined), the rectangular slide column 83 is slidably connected in the connecting cylinder 82, one side of the four rectangular slide columns 83 facing the center of the upper mold 1 is fixedly connected with the wedge-shaped butt joint mold plate 84 respectively, the demolding mechanism 8 further comprises an insertion plate 85, the insertion plate 85 is fixedly connected to the upper surface of the four wedge-shaped butt joint mold plates 84 respectively, then the external hydraulic rod can be adjusted and controlled, the external hydraulic rod is elongated to a specified length, thereby driving the upper mold 1 to move downward to a specified position. During this period, the wedge surface of the four wedge-shaped butt joint mold plates 84 will first contact the wedge surface of the bottom wedge-shaped mold groove 10 and maintain a sliding connection relationship. After the upper mold 1 moves downward to the specified position, the four wedge-shaped butt joint mold plates 84 form a lower side forming groove with the bottom wedge-shaped mold groove 10. During the formation of the four wedge-shaped butt joint mold plates 84 and the bottom wedge-shaped mold groove 10, the demolding frame 81 maintains a sliding connection relationship with the avoiding groove 4, thereby ensuring the stability of the lower side forming groove during forming. During this period, the rectangular slide column 83 will be retracted into the connecting cylinder 82 in turn, then the magnetic core raw material is added into the lower side forming groove, the external hydraulic rod is continuously adjusted and controlled, thereby driving the upper mold 1 to press downward at a specified pressure. When the four telescopic rods 86 are retracted to the shortest length, the upper mold 1 continues to press downward, the upper side wall of the top wedge-shaped mold groove 5 presses the magnetic core raw material in the lower side forming groove, during the pressing process, the insertion plate 85 will be inserted into the insertion groove of the top wedge-shaped mold groove 5, and the magnetic core raw material is pressed into a magnetic core. After the magnetic core is pressed and formed, the telescopic end of the external hydraulic rod is retracted, the upper mold 1 moves upward, when the four telescopic rods 86 are elongated to the longest length, the upper mold 1 continues to move upward, thereby driving the four wedge-shaped butt joint mold plates 84 to move upward. At this time, the lower side wall of the four wedge-shaped butt joint mold plates 84 will eject the formed magnetic core. After the upper mold 1 moves upward to the specified position, the sliding relationship with the wedge surface is lost, the formed mold will naturally loosen, and the magnetic core is in an unrestricted state at this time, so the magnetic core can be easily and quickly taken out.

[0028] The working principle of the magnetic core processing and pressing die provided by the utility model is as follows: when the pressing die needs to be used, the lower die 2 is installed on the specified work station, then the external limiting rods are sequentially inserted into the plurality of limiting holes 6, the hydraulic rod connecting seat 9 and the telescopic end of the external hydraulic rod are fixed, then the external hydraulic rod can be controlled, the external hydraulic rod is elongated by a specified length, and the upper die 1 is driven to move downwards to the specified position, during which, the wedge surfaces of the four wedge-shaped butt joint templates 84 first contact the wedge surfaces of the bottom wedge-shaped die grooves 10 and keep the sliding connection relationship, after the upper die 1 is moved downwards to the specified position, the four wedge-shaped butt joint templates 84 and the bottom wedge-shaped die grooves 10 form a lower side forming groove, during which, the rectangular slide posts 83 are sequentially retracted into the interiors of the connecting barrels 82, then the magnetic core raw material is added into the lower side forming groove, the external hydraulic rod is continuously controlled, and the upper die 1 is driven to press downwards with a specified pressure, when the four telescopic rods 86 are retracted to the shortest, the upper die 1 continues to press downwards, the upper side wall of the top wedge-shaped die groove 5 presses the magnetic core raw material in the lower side forming groove, the magnetic core raw material is pressed into a magnetic core, after the pressing and forming, the telescopic end of the external hydraulic rod is retracted, the upper die 1 moves upwards, when the four telescopic rods 86 are elongated to the longest, the upper die 1 continues to move upwards, and then drives the four wedge-shaped butt joint templates 84 to move upwards, at this time, the lower side wall of the four wedge-shaped butt joint templates 84 ejects the formed magnetic core, after the upper die 1 moves upwards to the specified position, at this time, the sliding relationship with the wedge surfaces is lost, the formed die is naturally loose, and the magnetic core is in the state of not being limited, at this time, the magnetic core can be easily and quickly taken out.
