Problems solved by technology

During mass production, the blanks are fired vertically (see Figure 1a-Figure 1c ) or flat burn (see Figure 3a-Figure 3c ) for close-packed sintering, due to the tight arrangement between the blanks, it is easy to stick to the blanks during the sintering process, resulting in bending and deformation of the final product; when the blanks are densely packed, it is difficult to deglue the blanks, and it is easy to cause degumming and cracking, which reduces the pass rate and affects product quality
[0005] In the process of realizing the present invention, the inventors found that there are at least some defects in the prior art, such as easy sticking of billets in the sintering process, difficulty in removing glue from blanks during dense packing, low qualified rate of finished products, low output and poor economic benefits.

Abstract

The invention discloses a forming die of an I-type manganese-zinc soft magnetic ferrite product. The forming die comprises a die body and multiple bulges, wherein the die body is used for pressing and forming an I-type manganese-zinc soft magnetic ferrite product; and multiple bulges are arranged on one side surface of the die body at intervals. The forming die of an I-type manganese-zinc soft magnetic ferrite product disclosed by the invention can overcome the defects of easy blank sticking in the sintering process, difficult glue discharge of blank in dense arrangement, low qualified rate of finished products, low output, low economic benefits and the like in the prior art, and can achieve the advantages of rare blank sticking in the sintering process, convenient glue discharge of blank in dense arrangement, high qualified rate of finished products, high output and high economic benefits.

Description

[0001] technical field [0002] The invention relates to the technical field of manganese-zinc ferrite magnetic material manufacturing technology, in particular to a molding die for I-type manganese-zinc soft ferrite products. Background technique [0003] Type I manganese-zinc soft magnetic ferrite is a ferrite with a wide range of applications. It is mainly used in various induction cookers and electric heating cookers. It is energy-saving and environmentally friendly. It is in great demand in the international and domestic markets. [0004] In the production process of type I manganese zinc soft ferrite products, the blanks are sintered in a close-packed manner, and a small amount of alumina powder is sprinkled between the blanks, which is very difficult, mainly because of its high flatness requirements, which are very difficult for the finished product. The deformation and bending requirements of the product are very strict, and the deformation and bending of the product...
