Automotive air vent structure components are assembled both sides of driver cab and passenger seat, part of the car air vent.Considering the comfort for driver and passengers, generally air vents are designed to be Symmetrical, 2 in the front and 2 in the middle(the central air vent is usually overall designed with two grilles). There’re 2 air vents in the driver’s cab, it is generally required that one of the air vent can make the airflow to the upper part of the driver's body (head, chest), which is called the upper body air outlet. And the other one can adjust the grille to make the air flow to the driver's entire body (head) , chest, knee), called the body outlet. Usually the upper body air outlet is located in the middle of the dashboard, the inner side of driver, while the body air outlet is located in either side of the instrument panel or door panel, outer side of driver.

For the design of the automotive air vent, the air outlet and the corresponding air duct design should be considered to ensure that the air conditioning wind can reach the required place, that is, the air conditioning wind out from the face outlet can be blown to the passegers’ face by adjusting teh direction of air grille, also the wind from the foot outlet can be effectively blown to driver and passenger feet place. To avoid the noise of the airflow through the outlet, the maximum air speed should not be more than 11m/s, generally between 6-11m/s.The direction of the face outlet usually can be adjusted, but the adjustable air outlet should be moderately damped① to avoid loosening due to vibration, displacement and noise. The adjustment space of the damper② should not be too long for the arrangement and connection of the duct.

The design of this auto air conditioner air vent components is provided by customer, and we support the mold design and manufacturing. In the mold design and development process, the mold distribution is generally determined by the functional use and mass production of the product. According to the function classifications, the automobile outlet mold can be divided into three types: the appearance part mold, the function part mold and the appearance function combined part mold. For example, the air outlet panel mold belongs to the appearance part mold, then the influence factor of the appearance quality is mainly considered in the product mold design. For example, the positioning rib design needs to consider the ratio of the rib to the wall thickness to be less than 1/3 (1/2), is there a Leather, painting or plating requirements. The gate effect for the product weld line③ quality and the matching relations with instrument panel(GAP,FLUSH) should also be considered for molds. The air vent grille mold is a combination of function and appearance requirements. The grille is generally made of reinforced glass fiber material. When the injection is filled, the appearance quality is mainly affected by the mold gate and the mold process control. The functional size is determined by the project quality positioning and the level of the mold manufacturing process. The shell of the air outlet belongs to the functional part mold, and the function carrier of the automobile air outlet is a relatively key part in the field of the air outlet mold, but the material used for the housing is generally modified PP based on factors such as material cost.

Keywords explanation for relative plastic products,

①Damping: refers to the characteristics of any vibration system in the vibration, the amplitude of the vibration is gradually reduced due to the external action or the inherent causes of the system itself, and the quantitative characterization of this characteristic. The physical meaning of damping is the attenuation of force, or the energy dissipation of an object during motion. In layman's terms, it is to prevent objects from continuing to move or move smoothly. When an object vibrates by an external force, a reaction force that attenuates the external force is generated, which is called a damping force (or damping force). Its ratio to force is called the damping coefficient. Usually the direction of the damping force is always opposite to the speed of the movement. Therefore, the greater the damping coefficient of the material, the better the damping or damping effect.

②Damper: The damper here mainly refers to the car damper, also known as the choke, which is used to adjust the amount of air entering. The function of the choke valve is to reduce the amount of air entering the inlet of the carburetor, increase the oil pressure at the fuel injection port, and increase the concentration of the mixture. It will be easier to start.

③Weld Line: During injection molding, the thin line produced at the confluence of the melt is called the weld line. The causes of the weld line may be: low injection pressure, slow injection speed, mold temperature, unreasonable use of release agent, poor mold discharge, low melt temperature, poor fluidity of the material, unreasonable gate setting, etc.
