Technical Field

[0001] The utility model relates to the technical field of molding dies, and particularly relates to a molding die for microcrystalline ferrite magnetic cores. Background Technique

[0002] A molding die, also known as a mold, is a mold made according to the shape and structure of an object in proportion, and is a tool for making materials into a certain shape by pressing or pouring. Ferrite magnetic cores are a kind of high-frequency magnetic conductive materials, mainly used for high-frequency transformers, high-frequency magnetic rings, etc. Ferrite magnetic cores have factors such as increasing magnetic permeability and improving inductance quality, and are commonly used in transformers. The raw materials of ferrite magnetic cores can be pressed into shape by using a molding die, and then the pressed raw materials of ferrite magnetic cores are sintered at high temperature to make ferrite magnetic cores.

[0003] However, most of the existing molding dies for microcrystalline ferrite magnetic cores are single-layer die designs, forming only one layer at a time, with low pressing efficiency. Moreover, the existing molding dies are not convenient for hoisting. The hoisting rings need to be installed when in use to prevent the hoisting rings from being damaged by collision during storage. To solve the deficiencies of the existing technology, we propose a molding die for microcrystalline ferrite magnetic cores. Summary of the Utility Model

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-3 shown, a forming die for microcrystalline ferrite magnetic cores includes a forming die main body 1. Positioning columns 2 are movably penetrated through the four corners of the top of the forming die main body 1. A bottom plate 3 is detachably installed at the bottom of the positioning column 2. The forming die main body 1 can be accurately placed on the bottom plate 3 through the positioning column 2. A hoisting assembly 5 is arranged in the first chute opened by the forming die main body 1. The forming die main body 1 can be hoisted through the hoisting assembly 5. Then, the upper pressing die assembly 4 is removed. The mold holes opened in the template 8 in the bottommost pressing die assembly 4 are filled with ferrite magnetic core raw materials. Then, the upper pressing die assembly 4 is placed back on the bottommost pressing die assembly 4. Repeat the above operations. Stack all the pressing die assemblies 4 and use the forming die main body 1 and the bottom plate 3 to press the raw materials in the mold holes of the template 8. Use the forming die main body 1 and the bottom plate 3 to apply pressure simultaneously from top and bottom to increase the pressure on the raw materials, and the pressing effect is better. The stacked pressing die assemblies 4 can press more ferrite magnetic cores at one time, improving the pressing efficiency.

[0023] As Figure 2 and Figure 4 shown, the hoisting assembly 5 includes a movable column 9. The movable column 9 is rotatably connected to the bottom of the inner wall of the first chute opened by the forming die main body 1. The top of the movable column 9 is connected through the top of the forming die main body 1. A square groove is opened at the top of the movable column 9. Rotate the movable column 9 through the square groove opened at the top of the movable column 9 to drive the movable ring 10 to rotate in the first chute opened by the forming die main body 1. The movable ring 10 drives the lead screw 11 to slide in the first chute opened by the forming die main body 1. The lead screw 11 drives the limit block 12 to drive the lifting ring 13 to slide in the first chute opened by the forming die main body 1. The lifting ring 13 can be conveniently stored. When the forming die main body 1 is not in use, the lifting ring 13 is stored back into the first chute opened by the forming die main body 1, which can effectively protect the lifting ring 13, prevent the lifting ring 13 from being damaged by collision, and also reduce the storage area required for the forming die main body 1, facilitating the storage of the forming die main body 1.

[0024] Working principle

[0025] It should be noted that the present utility model is a forming die for microcrystalline ferrite magnetic cores. When in use, first, turn the movable column 9 to overcome the frictional force between the movable column 9 and the forming die body 1. The movable column 9 drives the movable ring 10 to rotate in the first chute opened in the forming die body 1. The movable ring 10 drives the lead screw 11 to slide in the first chute opened in the forming die body 1. The lead screw 11 drives the limiting block 12 to drive the lifting ring 13 to slide out of the first chute opened in the forming die body 1. Then, turn the limiting block 12 and place the limiting block 12 vertically on one side of the forming die body 1. Then, turn the lifting ring 13 to drive the lead screw 11 to rotate. The lead screw 11 enters the movable ring 10 through the thread. The lead screw 11 drives the lifting ring 13 to push the limiting block 12 against one side of the forming die body 1 until the lifting ring 13 tightly presses the limiting block 12 against one side of the forming die body 1. Fix the position of the lifting ring 13 at this time to achieve the purpose of conveniently installing the lifting ring 13.

[0026] Lift the forming die body 1 through the lifting ring 13, then remove the upper pressing die assembly 4, fill the die holes opened in the template 8 in the lowermost pressing die assembly 4 with ferrite magnetic core raw materials, then place the upper pressing die assembly 4 back on the lowermost pressing die assembly 4, and repeat the above operations until all the pressing die assemblies 4 are stacked. Then, lift and place the forming die body 1 on the bottom plate 3 through the positioning column 2. Then, place the forming die body 1 and the bottom plate 3 on a hydraulic platform, and apply pressure simultaneously from above and below through the hydraulic platform to press the raw materials in the die holes of the template 8 in the stacked pressing die assemblies 4 within the forming die body 1 and the bottom plate 3 into shape, achieving the purpose of pressing multiple layers at one time.

[0027] After the pressing is completed, lift and remove the forming die body 1 from the bottom plate 3, separate the pressing die assemblies 4 layer by layer, then remove the template 8 on each layer of the pressing die assembly 4, and leave the formed ferrite magnetic cores on the positioning pins 7, thus completing the pressing of the ferrite magnetic cores.
