How Is Auto Side Skirt Mould Designed

 The design of auto side skirt mould is a complex process involving multiple technical fields. It requires designers not only to have excellent design capabilities, but also to have a profound engineering technical background and a deep understanding of materials and processing techniques. As an important part of a car's appearance, side skirts must be designed not only to meet aesthetic requirements, but also to meet the functional requirements of aerodynamics and vehicle protection.

Before designing auto side skirt mould, you need to have a comprehensive understanding of the functions and design requirements of the car side skirt. The main function of side skirts is to reduce the airflow from both sides of the car body into the bottom of the car, reduce air resistance, and improve the stability and fuel economy of the vehicle. At the same time, the design of the side skirts also needs to consider the coordination with the overall style of the vehicle and its role in protecting the vehicle bottom. Based on these requirements, the designer will draw a conceptual sketch of the side skirt and use professional 3D modeling software to create a 3D digital model of the side skirt.

The design of auto side skirt mould includes mold cavity, mold base, gate system, cooling system, exhaust system and demoulding mechanism. During the design process, material flow, shrinkage, and mold durability need to be taken into consideration. Computer-aided engineering (CAE) software is used to simulate and analyze the mold design to predict the filling, cooling and shrinkage of the side skirts during the injection molding process to ensure the feasibility of the design and the qualification rate of the product. After the mold design is completed, it will enter the manufacturing stage, which includes CNC machining, EDM, wire cutting and heat treatment to ensure the accuracy and durability of the auto side skirt mould.

After the mold is manufactured, a trial mold needs to be carried out to check the molding quality of the side skirts. Based on the mold trial results, necessary adjustments are made to the mold to eliminate defects and ensure stability and consistency during mass production. In the design of auto side skirt mould, material selection, cooling system, demoulding mechanism and surface treatment are all key design elements. Molds are usually made of high-performance steel, such as P20, 718 or H13, etc. These materials have good processing performance and wear resistance.

 To ensure rapid cooling and uniform shrinkage of the side skirts, an efficient cooling system needs to be included in the auto side skirt mould design. The complex shape of the side skirt requires the design of a precise demoulding mechanism to ensure that the side skirt can be smoothly separated from the mold and reduce the trimming work after molding. The mold surface usually requires special treatment, such as nitriding, chromium plating or coating, etc., to improve the durability of the mold and the appearance quality of the side skirts.

The design of auto side skirt mould not only requires designers to have excellent design capabilities, but also requires a profound engineering technical background and a deep understanding of materials and processing techniques. With the continuous development of the automobile industry, the design of auto side skirt mould is also constantly developing in a more efficient, environmentally friendly and economical direction. Through continuous technological innovation and process improvement, auto side skirt mould can better meet the market's demand for high-quality automotive exterior parts.
