Technical Field

The utility model relates to an one shot forming mould in the powder metallurgy field.

Background

Most automotive suspension systems incorporate shock absorbers therein. The shock absorber is mainly used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. While the shock absorbing spring can filter the vibration of the road surface when passing through the uneven road surface, the spring can reciprocate, and the shock absorber is used for inhibiting the spring from jumping. The working principle of the shock absorber is that when the frame or the wheels and the vehicle body are vibrated to generate relative motion, a piston in the shock absorber moves up and down, pressure oil in the shock absorber repeatedly flows into an oil storage cylinder of the shock absorber from a working cylinder of the shock absorber through different orifices, and at the moment, the friction between the hole wall and hydraulic oil and the internal friction between hydraulic oil molecules form damping force on the vibration, so that the vibration energy of the vehicle is converted into oil heat energy which is absorbed and emitted into the atmosphere by the shock absorber; be provided with the valve seat in the shock absorber, and the valve seat general condition all need form through the preparation of multichannel process, need carry out the secondary step turning moreover, has great inconvenience in the real-time of production, and the precision is relatively poor moreover.
