Automobile Molds Are Classified According To Process Propertie

  • Stamping dies in Automotive moulds can generally be classified according to the following main features:

    1. Classification according to the nature of the process
    2. Punching die: A die that separates materials along a closed or open outline. Such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc.
    3. Bending mold: A mold that makes the sheet blank or other blanks bend and deform along a straight line (bending line) to obtain a workpiece with a certain angle and shape.
    4. Drawing die: It is a die to make the blank of the sheet into an open hollow part, or to further change the shape and size of the hollow part.
    5. Forming mold: It is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging mold, necking mold, flaring mold, undulating forming mold, flanging mold, shaping mold, etc.
    6. Classification according to the degree of process combination
    7. Single process mold: In one stroke of the press, only one stamping process is completed.
    8. Compound mold: There is only one station, and in one stroke of the press, two or more stamping processes can be completed simultaneously on the same station.
    9. Progressive die (also called continuous die): In the feeding direction of the blank, there are two or more stations. In one stroke of the press, two or two passes are completed successively at different stations. Die for more than one stamping process.
    10. Classification according to the processing method of the product

    According to different product processing methods, molds can be divided into five categories: punching and shearing molds, bending molds, drawing molds, forming molds and compression molds.

    1. Punching and shearing die: the work is done by shearing. Commonly used forms are shearing die, blanking die, punching die, trimming die, edge die, punching die and punching die.
    2. Bending mold: It is a shape that bends the flat blank into an angle. Depending on the shape, accuracy and production volume of the part, there are many different forms of molds, such as ordinary bending dies, cam bending dies, curling Die, arc bending die, bending punching die and twisting die, etc.
    3. Drawing mold: Drawing mold is to make flat blank into seamless container with bottom.
    4. Forming die: refers to the use of various local deformation methods to change the shape of the blank. Its forms include convex forming die, curling edge forming die, necking forming die, hole flange forming die, and round edge forming die.
    5. Compression die: It uses strong pressure to make the metal blank flow and deform into the required shape. The types include extrusion die, embossing die, embossing die, and end pressure die.
