Description

Technical Field

[0001] This utility model relates to the field of mold technology for producing amorphous and nanocrystalline rectangular magnetic cores, specifically an amorphous and nanocrystalline rectangular magnetic core mold. Background Technology

[0002] Amorphous and nanocrystalline rectangular magnetic cores are widely used in power electronics, new energy, and communications due to their excellent soft magnetic properties (such as high permeability and low loss). The cores are typically manufactured using powder metallurgy, where amorphous and nanocrystalline alloy powder is filled into a mold cavity, and then pressed, sintered, and other processes are used to create the desired core shape.

[0003] Currently, traditional amorphous and nanocrystalline rectangular magnetic core molds typically employ a structure with upper and lower molds working together. The upper mold applies pressure to the powder to densify it and forms a magnetic core blank of a predetermined shape within the mold cavity. However, existing molds suffer from the following problems after molding:

[0004] 1. Difficulty in demolding: Due to the large friction and adsorption forces between the magnetic core blank and the mold cavity, it is difficult to remove the blank completely from the mold after molding.

[0005] 2. Simple structure: Traditional molds usually use fixed mold cores or integral mold cavities, which means that the material picking process relies on manual knocking or ejection devices, which is inefficient and easily damages the mold.

[0006] To address this, we propose an amorphous nanocrystalline rectangular magnetic core mold. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] This embodiment is an amorphous nanocrystalline rectangular magnetic core mold.

[0027] like Figure 1-4As shown, the system includes a base 1, with support columns 3 fixedly installed at the middle of the outer surfaces of both ends of the base 1. There are two sets of support columns 3, and a top plate 4 is fixedly installed between the upper outer surfaces of the two sets of support columns 3. A mold core structure 2 is installed at the upper end of the base 1. An upper mold structure 5 and a lower mold shell assembly 6 are installed on the top plate 4. The mold core structure 2 includes a third hydraulic rod 14, a base plate 15, a sliding hole 16, a mold core column 17, and a mounting cavity 18. The upper mold structure 5 includes a first hydraulic rod 7, a connecting block 8, a connecting arm 9, and a magnetic core upper mold 10. The lower mold shell assembly 6 includes a lower mold ring 11, a fixing block 12, and a second hydraulic rod 13. The mounting cavity 18 is opened inside the base 1. The base plate 15 is fixed to the upper outer surface of the base 1. The sliding hole 16 is opened between the middle of the upper outer surface of the base plate 15 and the middle of the upper outer surface of the base 1, and the lower end of the sliding hole 16 extends to the middle of the upper end of the mounting cavity 18.

[0028] A first through hole is provided in the middle of the upper outer surface of the top plate 4, and second through holes are provided on the left and right sides of the upper outer surface of the top plate 4. The cylinder of the first hydraulic rod 7 is fixed in the middle of the upper outer surface of the top plate 4. The piston rod of the first hydraulic rod 7 slides through the first through hole, and the piston rod of the second hydraulic rod 13 slides through the second through hole. The connecting block 8 is fixed in the lower outer surface of the piston rod of the first hydraulic rod 7. There are two sets of connecting arms 9, which are fixed between the outer surfaces of the two sides of the connecting block 8 and the upper outer surface of the upper mold 10 of the magnetic core. There are two sets of the second hydraulic rod 13 and the fixing block 12. The cylinders of the two sets of second hydraulic rods 13 are fixed in the middle of the upper outer surface of the top plate 4. At the left and right ends of the surface, the lower outer surface of the piston rod in the second hydraulic rod 13 is fixedly connected to the upper outer surface of the fixing block 12. The two sets of fixing blocks 12 are fixed in the middle of the upper part of the outer surface at both ends of the lower mold ring 11. The third hydraulic rod 14 is located in the mounting cavity 18. The third hydraulic rod 14 is fixed between the middle of the lower end of the mounting cavity 18 and the middle of the lower outer surface of the mold core column 17. The outer wall of the mold core column 17 is interference-fitted with the sliding hole 16. The outer wall of the upper mold of the magnetic core 10 is interference-fitted with the inner wall of the lower mold ring 11. The inner wall of the upper mold of the magnetic core 10 is interference-fitted with the outer wall of the mold core column 17. The outer wall of the mold core column 17 and the inner wall of the lower mold ring 11 form a mold cavity.

[0029] It should be noted that this utility model is an amorphous nanocrystalline rectangular magnetic core mold. During production, the lower mold ring 11 is first lowered by the operation of the second hydraulic rod 13 in the lower mold shell assembly 6, and then lowered to the upper outer surface of the substrate 15. At this time, the upper part of the core column 17 is located in the middle of the lower mold ring 11, as shown in the attached specification. Figure 1As shown, amorphous nanocrystalline alloy powder is then filled between the inner wall of the lower mold ring 11 and the outer wall of the mold core pillar 17. Then, the operation of the first hydraulic rod 7 in the upper mold structure 5 drives the upper mold 10 of the magnetic core to descend, inserting the lower end of the upper mold 10 between the outer wall of the mold core pillar 17 and the inner wall of the lower mold ring 11. After the blank is extruded and formed, unloading begins. First, the operation of the second hydraulic rod 13 drives the lower mold ring 11 to rise. The lower mold ring 11 rises along the outer wall of the upper mold 10 of the magnetic core until it reaches the upper part of the upper mold 10 of the magnetic core, making... The lower mold ring 11 is separated from the outer wall of the blank. Then, the operation of the first hydraulic rod 7 drives the upper mold 10 of the magnetic core to rise, so that the upper mold 10 of the magnetic core is separated from the upper outer surface of the blank. At this time, the blank is still fitted on the outer wall of the mold core column 17. The operation of the third hydraulic rod 14 drives the mold core column 17 to fall, so that the upper outer surface of the mold core column 17 falls into the sliding hole 16, so that the mold core column 17 is separated from the inner wall of the blank. At this time, the blank is located on the upper part of the substrate 15, and the operator can directly pick up the blank, improving the efficiency of material unloading.
