Abstract
The utility model relates to the technology field of aluminum die castings, and specially relates to a die-casting aluminum back cover of a motor. The die-casting aluminum back cover comprises a die-casting aluminum circular cover body, the center of the cover body is provided with a shaft aperture, a convex ring is arranged at the edge of the shaft aperture, a plurality of convex strips with arc-shaped top ends are distributed at the periphery of the convex ring in an annular form and are connected with the edge of the cover body, the top ends of the convex strips are provided with location holes, and the surface of the cover body is provided with a static powder layer by spraying. According to the die-casting aluminum back cover, the structure is simple, heat radiation performance is good, the surface of the cover body is provided with the static powder layer, thereby the protection and decoration performance is good, wear resistance and acid resistance are greatly enhanced, and the service life of the back cover of a motor is prolonged.
Description
Technical field
The utility model relates to aluminium diecasting technical field, especially a kind of aluminium die casting motor rear cover.
Background technology
Aluminium diecasting is a kind of part of compression casting, to use the compression casting machinery die casting machine that installs casting die, to be heated to be liquid aluminum or aluminum alloy and pour into the feeding mouth of die casting machine, through die casting machine die casting, the aluminium part or the aluminum alloy part that cast out the shape and size of mould restriction, such part is just called aluminium diecasting conventionally.Common aluminium die casting motor rear cover poor radiation, and be easily corroded, the useful life of motor affected.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide the motor cover of a kind of perfect heat-dissipating, long service life.
The utility model solves the technical scheme that its technical problem adopts: a kind of aluminium die casting motor rear cover, comprise the circular lid of aluminium die casting, in the middle of described lid, offer axis hole, described axis hole edge has a flange collar, described flange collar around annular spread to have complex root top be that the raised line of arc is connected with lid edge, described raised line top offers location hole, and described top surface is coated with electrostatic powder layer.
Further, the quantity of described raised line is three.
The beneficial effects of the utility model are that aluminium die casting motor rear cover of the present utility model is simple in structure, perfect heat-dissipating, and surface spraying electrostatic powder layer, protective and decorate properties are good, and the indexs such as resistance to wear, acid resistance also significantly improve, and have increased the useful life of motor cover.
