Description

Technical Field

[0001] The utility model belongs to the technical field of spraying processing, and specifically relates to an automatic demoulding spraying device. Background Art

[0002] The production process of NdFeB magnetic materials is a complex technical process, involving multiple steps such as extraction of rare earth elements, alloy preparation, magnetic field orientation, sintering, heat treatment and surface treatment. The following is the basic process of NdFeB magnetic material production: raw material preparation, alloy preparation, powder making, magnetic field orientation pressing, static pressing, sintering, heat treatment, surface treatment, machining.

[0003] When demolding the powder, a release agent is used. The method is to place a brush and a measuring cup filled with the release agent inside the equipment. Each time the material is poured, a brush is dipped in the release agent and brushed into the mold cavity. All five surfaces must be brushed, and the wrist must be strong. Otherwise, the bottom cannot be brushed, which will cause unsmooth demolding and direct edge and corner fall-off. The product's one-time appearance pass rate is very low. Manually applying the release agent is not only time-consuming and labor-intensive, but may also cause the brush to shed or residual powder to stick to the brush, which will result in impurities in the mold cavity and affect the demolding pass rate.

[0004] In view of this, the present utility model is proposed. Utility Model Content
