Problems solved by technology

[0003] And because the wheel hub of many minicars is relatively small, in order to be attractive in appearance and protection, all can add an outer cover on the outside of wheel hub, but many outer covers all can break after bumping, bumping, also have many to be made of plastics, like this The safety performance is not high

Embodiment Construction

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0018] A wheel hub cover of a miniature car is characterized in that: the distribution ratio of each component is calculated as follows in weight fraction,

[0019]

[0020] A preparation method for a wheel hub cover of a miniature car comprises,

[0021] Ⅰ Make different styles of molds and runners according to the needs through paraffin, and then add CuO and Al 2 o 3 melt into a liquid;

[0022] Ⅱ Place the paraffin in the sprue, coat a layer of internal release agent on the surface of the paraffin, and then wrap a layer of quartz sand;

[0023] ⅢPour CuO liquid and Al into the sprue immediately after the completion of Ⅱ 2 o 3 Liquid, mixed molding;

[0024] ⅣPut the molded material into the baking machine and bake. When the paraffin wax melts, pour the polyethylene resi...

Abstract

The invention relates to the technical field of casting of car accessories, in particular to a hub outer cover of a minicar. The hub outer cover of the minicar is characterized by comprising the following components: by mass, 7.5-18.5 parts of polyethylene resin powder, 15-28 parts of quartz sand, 75-95 parts of CuO, 75-95 parts of Al2O3, 25-40 parts of fiber glass filaments, 4.5-12.5 parts of release agents and 5-15 parts of Na2SO4. The method is reasonable. The proportion is clear. The hardness of products is high.

Description

Technical field: [0001] The invention relates to the technical field of auto parts casting, in particular to a hub outer cover of a miniature car. Background technique: [0002] In the past, most car wheel bearings used single-row tapered roller or ball bearings in pairs. With the development of technology, cars have widely used car hub units. The use range and amount of hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with nuts. Makes car maintenance easier. The third-generation hub bearing unit uses the combination of the bearing unit and the anti-lock brake system. The hub unit is designed to have an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the ent...
