The Function Of The Auto Bumper
1. Protection function – bumper should absorb part of the energy in the longitudinal and corner collision of the car to protect the body, vehicle lighting system, cooling system, engine cover, gift box cover, etc.; pedestrian protection function, in the bumper The lower part is equipped with a buffer block to better protect the calf injury value when a pedestrian collides.
2. Device functions – on the bumper, some are equipped with lamps, license plates and license plates, etc., to give enough space and equipment conditions;
3. Ventilation channel – providing ventilation channels for vehicle cooling systems.
4. Decoration function – the appearance decoration function integrated with the body shape.
5. Improve aerodynamic characteristics —— The optimal design of the front bumper has obvious effect on reducing the front windward resistance coefficient and lift coefficient.

The Sturcture Of Bumper &. Mold
1. Wall thickness
The larger the demolding angle, the easier the part is to be demolded, but it is easy to cause uneven thickness of parts and affect manufacturing precision.
2. Reinforcing ribs
Reinforcement must be applied at some points such as holes, large curved surfaces or mounting points to increase strength and rigidity. The main surface of the exterior part is generally not suitable for reinforcement. When the subsurface is reinforced, the wall thickness of the root is not greater than 3/ 4 of the wall thickness, and the surface quality is low or non-visible.
3. Rounded corners
The minimum fillet for a typical part is R0.5, but the parting surface is not rounded, otherwise it will increase manufacturing costs and difficulty. The hole-hole shape should be as simple as possible, and the hole should be kept at a certain distance from the wall. The hole-to-boundary minimum is at least 1.5 times the aperture.
4. Inner parting structure
In the design of the auto bumper mold, to ensure the appearance quality of the bumper, the inner parting line is set on the invisible B side, so that the processing error or the flash produced by the mold after long-term production will not affect the appearance quality of the product.
