Description

Technical Field

[0001] The utility model relates to the technical field of oblique orientation die attachment devices, in particular to an oblique orientation molding device for preparing magnetic materials. Background Art

[0002] Materials that can respond to magnetic fields in some way are called magnetic materials. According to the strength of the magnetism of the material in the external magnetic field, it can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and they react weakly to the external magnetic field. Ferromagnetic materials and ferrimagnetic materials are strong magnetic materials. The so-called magnetic material molding refers to the strong magnetic material molding. Magnetic material molding is generally divided into soft magnetic materials and hard magnetic materials according to the difficulty of magnetization. The application of magnetic material molding has been widely used in all aspects of people's lives. In the production of magnetic material molding, it is necessary to press the powdered raw materials into block blanks, which requires the application of molding machines;

[0003] In the traditional magnet block production process, the mold cavity shape of the obliquely oriented magnet is rectangular. When the obliquely oriented magnet is produced, the mold is placed on a magnetic field forming press for pressing. Since the mold cavity shape is rectangular, the prepared magnet cannot change the orientation of the magnetic lines of force, and the orientation angle of the magnetic lines of force cannot be changed. Normal square products must be produced first and then processed by electric spark wire cutting. This method consumes electricity and time, and will also produce about 20% of waste, which significantly increases production costs. In addition, processing may cause cutting size errors, so it is not practical. Utility Model Content
