Description

Technical Field

[0001] The utility model relates to the technical field of magnetic materials, in particular to a mold for producing high-shielding magnetic materials. Background Art

[0002] Permanent magnetic materials have been widely used in many fields such as electronic information, automotive industry, medical equipment, energy and transportation. At the same time, with the continuous advancement of technology and the continuous reduction of costs, NdFeB permanent magnetic materials have shown broad application prospects in many emerging fields.

[0003] An existing mold for magnetic materials (publication number: CN208495718U) can improve the efficiency of single-time magnetic material production, but since the mold cannot press the magnetic material during production, the density of the product may be uneven after the magnetic material is produced. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a mold for the production of high-shielding magnetic materials to solve the problem mentioned in the above background technology. However, since the mold cannot press the magnetic material during production, this may lead to uneven product density after the magnetic material is produced.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold for producing high-shielding magnetic materials, including a mold main body, a circular groove is opened in the middle position of the upper surface of the mold main body, rectangular grooves are opened at both ends of the upper surface of the mold main body, and a plurality of positioning holes are opened on the upper surface of the mold main body. The upper end of the mold main body is connected to a mounting plate by positioning bolts, a plurality of buffer springs are fixedly installed on the bottom of the mounting plate, a plurality of through holes are opened on the mounting plate, and the buffer springs are located between the positioning holes and the through holes. A circular protrusion block is fixedly installed on the bottom of the mounting plate at the middle position, and rectangular protrusion blocks are fixedly installed on the bottom of the mounting plate at both ends.

[0006] By adopting the above technical scheme, the magnetic material is injected into the circular groove and the rectangular groove opened on the mold body to facilitate subsequent molding. After the magnetic material is injected into the circular groove and the rectangular groove, the through holes opened on the mounting plate are aligned with the positioning holes opened on the upper surface of the mold body, and then the positioning bolts are inserted into the through holes. After the positioning bolts are inserted into the through holes, the positioning bolts are rotated so that they are inserted into the positioning holes opened on the upper surface of the mold body. Then, because a buffer spring is installed at the bottom of the mounting plate, and the buffer springs are located at the bottom of the through holes, when the positioning bolt drives the mounting plate to be pressed down, the buffer spring will contact the surface of the mold body, so that the mounting plate is slowly pressed down, ensuring the stability of the magnetic material during the pressing process. Then, because the diameter and width of the circular protrusion block and the rectangular protrusion block set at the bottom of the mounting plate are equal to the diameter and width of the circular groove and the rectangular groove, they can be better embedded in the circular groove and the rectangular groove, so as to facilitate the pressing of the magnetic material in the circular groove and the rectangular groove, and also ensure that the density distribution of the product after pressing is uniform.

[0007] Preferably, a positioning bolt is inserted into the through hole provided on the mounting plate, and the positioning bolt can connect the mounting plate with the mold body.

[0008] By adopting the above technical solution, after the product is manufactured, the positioning bolt can be rotated to be taken out from the positioning hole. After the positioning bolt is taken out, the mounting plate can be removed from the mold body without restriction, and the operation is relatively simple.

[0009] Preferably, a rectangular clamping plate is arranged in the rectangular grooves opened at both ends of the mold body, a clamping slot is opened at the right side of the rectangular clamping plate, a clamping block is arranged at the right side of the rectangular clamping plate, the diameter of the clamping block is consistent with the diameter of the clamping slot, and connecting grooves are opened on both side end faces of the rectangular clamping plate.

[0010] By adopting the above technical solution, the card slot opened on the right side of the rectangular card plate can be connected to the card block set on the left side of the rectangular card plate, so as to protect the product after the product is completed, and it is also convenient for the subsequent demolding of the product. Then the connecting grooves opened on both sides of the rectangular card plate facilitate the connecting bolts to push it.

[0011] Preferably, a circular clamping plate is arranged in the circular groove, a clamping slot is opened on the left side of the circular clamping plate, a clamping block is arranged on the right side of the circular clamping plate, the diameter of the clamping block matches the diameter of the clamping slot, and connecting grooves are opened on both side end faces of the circular clamping plate.

[0012] By adopting the above technical solution, the card slot opened on the left side of the circular card plate can be connected to the card block set on the right side of the circular card plate, so as to protect the product after the product is completed, and also facilitate the subsequent demolding of the product. Then the connecting grooves opened on both sides of the circular card plate facilitate the connecting bolts to push it.

[0013] Preferably, three connection holes are provided on both side end surfaces of the mold body, and connection bolts are inserted into the three connection holes.

[0014] By adopting the above technical solution, the connecting bolts are inserted into the connecting holes opened on both sides of the mold body, and then the connecting bolts are rotated to move toward the mold body. Then the connecting bolts will push the rectangular card plate and the circular card plate inward through the connecting grooves opened on both sides of the rectangular card plate and the circular card plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The mold for producing high-shielding magnetic materials has a circular protrusion block and a rectangular protrusion block arranged at the bottom of the mounting plate, and the diameter and width of the circular protrusion block are equal to the diameter and width of the circular groove and the rectangular groove, so that the circular groove and the rectangular groove can be well embedded in the mold, so as to facilitate the pressing of the magnetic material in the circular groove and the rectangular groove, and also ensure the uniform density distribution of the product after pressing.

[0017] 2. This mold for producing high-shielding magnetic materials takes the finished product out of the circular groove and the rectangular groove, and then removes the rectangular pallet and the circular pallet surrounding the product for subsequent use. At the same time, after the product is completed, the rectangular pallet and the circular pallet can play a certain protective role for the product. BRIEF DESCRIPTION OF THE DRAWINGS
