Description

Technical Field

[0001] The utility model relates to the technical field of magnet materials, in particular to a magnet cold isostatic pressing die. Background Art

[0002] A magnet is a magnetic object that can generate a magnetic field and attract or repel other magnetic objects. Magnets are widely used, for example, in electric motors, generators, speakers, maglev trains and other equipment. The properties and characteristics of magnets depend on factors such as their material, shape, and size. Common magnet materials include metals such as iron, cobalt, nickel, and some rare earth elements. Different magnet materials have different magnetic strengths and stabilities. Cold isostatic pressing molds are usually used during the molding process to improve their quality.

[0003] Traditional cold isostatic pressing molds usually include a mold body, seals and other parts. The mold body is generally made of high-strength metal materials to withstand high pressure and high temperature. The seals are used to ensure the high-pressure environment inside the mold and prevent pressure leakage. They can perform isostatic pressing on materials under high-pressure environments to improve the density and uniformity of the materials. The mold structure is relatively simple and easy to operate. It can be applied to the molding processing of a variety of materials.

[0004] However, the traditional cold isostatic pressing mold usually has an integrated inner shell and an outer shell, which means that when magnets with different requirements need to be processed, the entire mold must be replaced. Replacing the entire mold not only reduces production efficiency and increases costs, but also wastes time. In order to adapt to different processing requirements, the mold needs to be replaced frequently, which has an adverse effect on production progress. In addition, replacing the entire mold requires additional storage space to store spare molds, further increasing the company's operating costs. Therefore, a magnet cold isostatic pressing mold is proposed to solve the above problems. Utility Model Content
