Abstract

The invention discloses a multi-pole magnetic ring progressive orientation mold and an orientation method thereof, and solves the technical problems that products prepared by an orientation mold and an orientation method in the prior art are large in upper and lower pole difference and different in surface magnetism. The mold comprises a mold core (1) and a mold sleeve (2) arranged on the outer side of the mold core (1), wherein an annular gap is formed between the mold core (1) and the mold sleeve (2); a cavity is formed in at least one of the mold core (1) and the mold sleeve (2), a movable orienting device (5) is arranged in the cavity, and the orienting device (5) is connected with a controller; and an upper pressing head (3) matched with the annular gap in size is arranged at the upper end of the annular gap, and a lower pressing head (4) matched with the annular gap in size is arranged at the lower end of the annular gap. The mold is used for preparing the multi-pole magnetic ring, the upper and lower pole difference of the multi-pole magnetic ring can be effectively reduced, and the working performance of the multi-pole magnetic ring is improved.

Description

technical field [0001] The invention relates to an orientation mold of a multi-pole magnetic ring and an orientation method thereof, in particular to a progressive orientation mold of a multi-pole magnetic ring and an orientation method thereof. Background technique [0002] Multi-pole magnetic rings are widely used in new generation products such as stepping motors, instruments, sensors, timers, etc., especially for multi-pole magnetic ring permanent magnet motors. Motors (such as electric excitation motors, bonded permanent magnet multi-pole rotor motors) have the advantages of simple structure, small size, and good stability. [0003] The orientation molding process is the core process of producing anisotropic multi-pole magnetic rings. The current general steps are: the mold sleeve and the lower pressure head move downward, and the mold core remains unchanged. The three form a preset cavity volume and are filled with fillers. The material box moves back and forth above ...
