Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 with figure 2 As shown, the forming mold of the soft ferrite core provided by the embodiment of the present invention is used to process ferrite powder into a soft ferrite core, which includes an upper mold 1 and a concave mold arranged under the upper mold 1 2. The lower mold 3 arranged under the die 2 has a cavity 21 on the die 2. Specifically, the cavity 21 is arranged in the middle of the die 2, and the cavity 21 axially runs through the die 2. The cavity 21 is used to fill ferrite powder a inwardly, the bottom of the upper die 1 has a die punch 11, the top of the low...

Abstract

The invention relates to the die equipment field, and discloses a soft magnetic ferrite magnetic core forming die comprising an upper die, a concave die arranged below the upper die, and a lower die arranged below the concave die; the concave die is provided with a cavity; the bottom of the upper die is provided with an upper die punch; the top of the lower die is provided with a lower die punch; the upper and lower die punches penetrate the cavity; the upper and lower dies are made of high speed steel; the roughness of the end faces and side wall faces of the upper and lower die punches can be below Ra 0.008 micron after surface treatment. The upper and lower dies are made of high speed steel; surface treatment is carried out on the upper die punch on the bottom of the upper die and the lower die punch on the top of the lower die, thus allowing the roughness to be Ra 0.008 micron, thus greatly improving wear resistance and hardness of the upper and lower die punches, providing good fineness and impact resistance capability, greatly improving appearance quality of the formed soft magnetic ferrite magnetic core, and improving die production efficiency and repetition utilization rate.

Description

technical field [0001] The invention belongs to the field of mold equipment, in particular to a forming mold for a soft ferrite core. Background technique [0002] Soft magnetic ferrite is a kind of magnetic material with the most varieties, the widest application and the largest consumption. It is an important basic functional material in the electronic information and home appliance industries. After more than half a century of scientific research and production by ferrite companies in various countries, the performance of soft ferrite has been greatly improved and enhanced, its output has increased rapidly year by year, and the scope of application fields has also continued to expand. [0003] In the prior art, soft ferrite cores are mostly formed by molding, sintering and other processes. Taking nickel-zinc ferrite cores as an example, taking Fe 2 o 3 , ZnO, NiO, CuO as the main raw materials, through five processes of mixing, pre-calcination, ball milling, granulation...
