Air conditioner windshield is widely use in summer or winter. And this one is not a complex part. It is made by some screw and plastic parts. Could adjust the wind directions.
But due to the length is little long, so normally will separate it as different parts. However, one plate length also around 500mm, and do not have ribs in the surface. So it is easy to buckling deformation.

When we make the air conditioner windshield mold design, we need to focus on verifying and optimizing multiple core parameters in a targeted manner. From the four dimensions of mold structure, injection system, cooling line and demold design, we should solve the buckling deformation problem of long, thin and ribbed plastic parts from the source to ensure the stability of mass production and the accuracy of finished products.

For the air conditioner windshield mold, the gate position and injection system are very important. The single tip will cause the product out of shape and bend due to the length is around 500mm, and when inject, the material easy to be freeze when flow. Then cause it is not easy to full. So if your air conditioner windshield length is 500mm or more, then recommend to use multi-tip gate, or side gate to reduce the material melt distance, and then the product is easy to full. And the product is not easy to bend.

In the same time, we need to consider the demold way. Because the air conditioner windshield normally do not have rib on the part. Then it is easy to bend. If the ejection point is unreasonable and the ejection force is uneven, white ejection, depression and bending deformation will directly occur during the demolding process.
When designing, the layout of the ejector pins should be optimized. The ejection structure should be evenly arranged at key force-bearing points such as the ends and middle of the plastic part to ensure balanced and smooth ejection during demolding and prevent secondary buckling deformation caused by external forces during demolding.

In conclusion, although the air conditioner windshield mold seems to have a simple structure, its special structure of long size, thin wall and no ribs makes the mold design threshold much higher than that of ordinary household appliance plastic parts. Only through precise shrinkage compensation, balanced glue feeding system, symmetrical cooling layout and stable demolding structure, and by comprehensively avoiding buckling deformation defects, can high-precision, high-yield and stable mass production of wind deflector plates be achieved, taking into account product appearance, assembly accuracy and service life.
