Description

Integral type drains the stator module of pump motor

Technical field

The utility model is related to a kind of washing machine, dish-washing machine, refer in particular to the draining pump electricity on washing machine, dish-washing machine Machine.

Background technology

China Patent No. 201320745113.5 discloses a kind of synchronous motor draining pump, which does not have with rotor There is protective materials to be isolated, lead to draining pump in the process of running, water, which easily infiltrates into iron core or coil, causes iron core to get rusty Or coil short.For this purpose, someone has developed a kind of waterproof draining pump motor, as application for a patent for invention number is Winding, is wrapped on skeleton by a kind of draining pump motor and preparation method thereof that CN201410362395 is announced first, then Skeleton and winding are put into mold plastic packaging, obtain coil sealing.Two that finally U-shaped iron core assembly to winding sealing is reserved In a slot, U-shaped iron core must ensure that iron core cannot be loosened with coil after being packed into winding sealing, when otherwise washing machine works Vibrations can cause drain pump coil wave.In this patent application, since the assembly of iron core and coil is along iron core pressing direction （Up and down）Degree of freedom do not limit, it is necessary to be interference fitted by back and forth or left and right direction and limit the degree of freedom of coil and iron core. But since coil overmold size is by Shooting Technique（Temperature, pressure）, cooling condition, the factors such as die venting influence, especially The extremely difficult control of size of two square holes coordinated with iron core, cause production process be susceptible to iron core can not be pressed into coil or By coil pressure break situation；And it is unstable due to the size, production process is also easy to cause the dress of U-shaped iron core and coil overmold Not enough loosening is generated with interference volume.Therefore, the preparation method is other than technological requirement is relatively high, U-shaped iron core and iron core inner cavity There are gap, skeleton is difficult to accurately be positioned surrounding, and the quality for also resulting in product is difficult to management and control, high rejection rate.

Important component of the stator module as draining pump motor, what iron core was encased in after skeleton between them close matches It closes, positioning, quality when to plastic packaging below just seem most important.

Invention content

The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of more reasonable structure are provided, in integral type It can be convenient for iron core positioning and plastic packaging effect better integral type draining pump motor stator component when plastic packaging motor, help to improve The yield rate of integrated plastic packaging.

In order to solve above-mentioned technical problem, the utility model uses following technical proposals：

A kind of stator module of integral type draining pump motor, including skeleton, the enameled wire being wound in the wire casing of the skeleton, dress The connecting terminal being connect outside the skeleton and with enameled wire both ends, the U-shaped iron core being pressed into a pair of of iron core perforation of the skeleton, And the plastic part that the cross edge of skeleton, enameled wire and iron core is disposably coated togather, the skeleton top should in opposite direction It is respectively equipped with raised locating piece on the position of the cross edge both sides of iron core；It is equipped on the iron core perforation inner wall of the skeleton several A positioning bar for being used for closely compressing on the inside of the vertical edge portion with iron core；The raised locating piece and positioning bar and the skeleton 1 one Body injection molding.

To above-mentioned integral type drain pump motor stator module improvement project in, the positioning bar upper end be equipped with to Under guiding surface.

Compared with prior art, the beneficial effects of the utility model：Since skeleton top is in the cross edge of the opposite iron core It is respectively equipped with raised locating piece on the position of both sides, and is used for equipped with several on the iron core perforation inner wall of skeleton and iron core Vertical edge portion on the inside of the positioning bar that closely compresses, when in the iron core that U-shaped iron core is encased in skeleton being perforated, the cross edge of iron core Jacked up by raised locating piece, vertical edge portion is then clamped with positioning bar, then from longitudinally, laterally skeleton and iron core can be positioned completely It is good, and since core dimensions is stable, is not easy to be influenced by Shooting Techniques such as injection temperature, pressure and deforms, it is moulding in this way It can be molded by stable quality, reliable stator module by the way that iron core is accurately positioned in envelope mold, to improve plastic packaging Yield rate, therefore the more reasonable structure of the utility model, greatly improve the yield rate of draining pump motor integral plastic packaging.

The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
