Motor stator packaging mold

Abstract

The invention provides a motor stator packaging mold which comprises a lower mold and an upper mold. The lower mold comprises inner positioning columns, outer positioning columns, bosses, a reinforcing rib groove, leading-out end notches, a connecting end notch, straight sheet accommodating notches and ejector rod column holes, the inner positioning columns are uniformly annularly arrayed, the quantity of the outer positioning columns is equal to that of the inner positioning columns, and outer rings of the outer positioning columns are uniformly annularly arrayed; the upper mold comprises inner positioning holes, outer positioning holes, straight sheet embedding notches, bosses, a reinforcing rib groove and a high-polymer material injection port, and the inner positioning holes, the outer positioning holes and the straight sheet embedding notches correspond to the outer positioning columns, the outer positioning columns and the straight sheet accommodating notches in the lower mold. The motor stator packaging mold has the advantages that effects of forming coils at one step can be realized in compression procedures during use, and processes are simple; reinforcing ribs can be automatically arranged on motor stators, radiating through holes can be automatically formed in the motor stators, the coils cannot be easily pulled out when motors are used, and good radiating effects can be realized; effects of positioning the coils can be realized by the inner positioning columns, the outer positioning columns and the bosses, covering layers can be generated on the surfaces of the coils by means of pouring, and accordingly the shape and position accuracy of the coils and the consistency of batch production products can be guaranteed.

Description

technical field [0001] The invention relates to the field of disc motors, in particular to a packaging mold for a motor stator. Background technique [0002] Disc motors have many advantages such as small size, light weight, compact structure, and high efficiency, and are widely used in various industrial equipment. In order to prevent the coils of the motor stator from falling off during use, the stator of the disc motor needs to be packaged before it can be used. [0003] Invention patent (patent number: CN201010243892.X) discloses a disc motor coil shaping device and its use method. It includes an upper mold, a gasket, a support ring, and a lower mold; a step is provided on the lower mold, and a cylinder is arranged at the center and around the step of the lower mold, the support ring is set on the step of the lower mold, and the gasket passes through the cylinder on the step of the lower mold The body is placed on the upper surface of the lower mold step, and the upper...

AI Technical Summary

Problems solved by technology

The special-shaped coils in this technical solution can only be installed after a specific shape, and the manufacturing process of the motor stator is complicated

[0006] In summary, the main defects of the existing technology are: first, in terms of coil shaping and shaping, only individual coils can be shaped and shaped, and there is a lack of a technical solution for overall shaping and shaping of stator coil windings; Second, because there is no reinforced structure, the stator plate is prone to coil detachment during use
