Abstract
The utility model relates to a gasket of a rotating shaft of a notebook computer, which comprises a gasket body, a cylindrical positioning point is arranged at the upper part of the gasket body, a round through hole is formed at the lower part of the gasket body, crescent oil-accommodating grooves are arranged symmetrically at the upper and the lower parts of the round through-hole, and four concave positioning grooves are distributed radially on each of the two sides of the round through-hole. The gasket has the benefits of simple molding process, low production cost and the same using function as the MIM parts after assembly.
Description
Technical field
The utility model relates to a kind of pad, relates in particular to a kind of notebook rotating shaft pad.
Background technique
Because rotating shaft at present uses metallic dust injection molding (Metal Injection Molding) to be called for short MIM again, this processing procedure of MIM system becomes mixing materials metallic dust and binder are mixing, again this material heating, batch mixing after being heated via injector is then injected in the mould and is shaped the living embryo after the shaping, need process through degreasing, the binder of before having sneaked into is removed, and sintering again can obtain density 95% above high density, high-intensity product behind the sintering.But this need cooperate through complicated forming process and the high relatively mould of precision requirement, and is many for also increasing on the cost.
The model utility content
The purpose of this utility model provides a kind of notebook rotating shaft pad, uses the too high deficiency of MIM pad cost to overcome present rotating shaft.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of notebook rotating shaft pad, comprise gasket body, the top of described gasket body is provided with the cylinder locating point, the bottom of gasket body is provided with manhole, the above and below of described manhole is provided with symmetrical crescent shape oil storage tank, and the both sides of manhole respectively are provided with the concavity locating slot of four radial distributions.
The beneficial effects of the utility model are: forming method is simple, has saved cost of production, and by reaching after the assembling and using the identical function of use of MIM part.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below:
Fig. 1 is the plan view of the described notebook rotating shaft of the utility model embodiment pad;
Fig. 2 is the left view of the described notebook rotating shaft of the utility model embodiment pad.
Among the figure:
1, gasket body; 2, concavity locating slot; 3, crescent shape oil storage tank; 4, cylinder locating point; 5, manhole.
Embodiment
Shown in Fig. 1-2, the described a kind of notebook rotating shaft pad of the utility model embodiment, comprise gasket body 1, the top of described gasket body 1 is provided with cylinder locating point 4, the bottom of gasket body 1 is provided with manhole 5, the above and below of described manhole 5 is provided with symmetrical crescent shape oil storage tank 3, and the both sides of manhole 5 respectively are provided with the concavity locating slot 2 of four radial distributions.
During making, adopt the method for press tool moulding,, obtain required shape through the extrusion process that forces of mould by the die cavity that mould presets.
