Abstract

The invention relates to a motor seat mould of an electric tool, comprising fixing plates, moulds, guide columns, thimble plates and a nozzle, wherein a lower thimble plate (11) and an upper thimble plate (10) are arranged above a lower fixing plate (12) from bottom to top; a male mould (8) is arranged above the upper thimble plate (10) and a female mould (2) is arranged on the male mould (8); an upper fixing plate (1) is arranged on the female mould (2); inclined guide columns (6) are arranged in cavities of the female mould (2) and the male mould (8) in a bilateral symmetry manner; slide blocks (4) are mounted on the inclined guide columns (6) and a male mould core (7) is mounted in a cavity formed below the slide blocks (4) by the male mould (8); a female mould core embedding piece (3) is mounted in a cavity formed above the slide blocks (4) by the female mould (2); and the central position of the upper end of the female mould core embedding piece (3) is communicated with a hot nozzle (13) on the upper fixing plate (1). According to the motor seat mould of the electric tool, the accuracy of the size, and the concentricity and the roundness of a stator can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric motors, in particular to an electric tool motor seat mold. Background technique [0002] With the rapid development of modern industry, more and more electric products are used in the power devices of household and garden tools all over the world. In order to ensure that electric tools have low noise, good power, good performance and long life during use, this The use quality and service life of electric products put forward higher requirements. For example, the stator chamber of the motor seat and the motor stator must have precise concentricity and perfect roundness. In the traditional design of the stator chamber of the motor seat, the mold is considered. The demoulding slope is generally placed at a demoulding angle of more than 0.5 degrees, which will cause loosening or even shaking when the lower part is tight to the upper part when assembling with the stator, and the concentricity cannot b...
