  • The design and mold flow analysis of automobile window frame molds are key process links. The following are some key design and analysis aspects generally involved:

    Key points of mold design
    Structural Design: The window frame mold needs to take into account the shape, size and structure of the window frame to ensure that these complex shapes can be accurately formed.

    Material Selection: Choose a suitable mold material, usually tool steel with high hardness, high strength and wear resistance, to ensure the service life and stability of the mold.

    Cooling system design: Design a reasonable cooling system to ensure that plastic materials can be cooled quickly during injection molding and reduce quality problems caused by uneven deformation and shrinkage.

    Gate design: Reasonable gate design can ensure uniform melt filling and reduce defects such as bubbles and short injection.

    Mold processing accuracy: Mold processing requires high precision to ensure the size and surface quality of the final product.

    Mold flow analysis details
    Filling Simulation: Simulate the filling process of melt in the mold cavity, and evaluate parameters such as filling time, filling pressure, and filling speed to predict possible defects such as poor filling, bubbles, and short injections.

    Cooling Simulation: Conduct cooling simulation to evaluate parameters such as cooling time, temperature distribution and shrinkage to ensure uniform cooling of the entire window frame and reduce quality problems caused by uneven deformation and shrinkage.

    Thermal Stress Analysis: Analyze thermal stress and design a reasonable structure and cooling system to reduce the impact of thermal stress on product quality.

    Mold structure optimization: Based on the mold flow analysis results, the mold structure is optimized, including optimization of the cooling system, gate design, etc., to improve product molding quality and production efficiency.

    The above are the general key points of mold design and mold flow analysis. These processes and analyzes are critical to ensuring the production quality and efficiency of automotive window frames.
