What do you use auto mould? How is the mould is classified? The principal part of the auto mould is covering parts mold. This kind of mold is mainly cold punching die. "In the broadest sense of the auto mould" is to make cars in all parts of the mold. For example, stamping mold, injection mold, forging mold, casting wax mold, glass mould, etc. The car body stamping parts can be broadly divided into covering parts, beams and general stamping parts. Can clearly said car image characteristics of stamping parts is automotive covering parts. As a result, more specifically auto mould can say as a "automotive covering parts stamping mould. Hereinafter referred to as automotive covering parts stamping die. For example, the vehicle door plate trimming die, car door panel punching die, etc. Of course the car not only car body stamping. Cars all stamping mould are referred to as the "auto stamping die". Sum up is: 1. Auto mould is making cars in all parts of the mold. 2. Automotive stamping die is coining on all stamping mould. 3. The car body stamping die is all coining car body stamping mould. 4. Automotive covering parts stamping die is all coining car body covering parts of the mold. Now we say the plate auto mould seemed refers to the automobile cover parts die. A lot of stamping die, die also in accordance with the nature of work, die structure, die materials three aspects to classification. Can generally be classified by the following main features: 1. According to the nature of technology category a. blanking die along a closed or open the contour line for separating materials to produce the mold. Such as blanking die, punching die, die cut mold, cut, blanking die, die cutting, etc. B. bending die making sheet metal blank or other come along a straight line (curved line) to produce bending deformation, thereby gaining a certain Angle and shape of the workpiece in the mold. C. deep drawing die is made the sheet metal blank opening hollow, hollow or make a further change shape and size of the mold. D. forming die is blank or semi-finished workpiece according to the figure forming, the shape of convex and concave die directly copy the material itself only produce local plastic deformation of the mold. Such as bulging die, reducing die, flaring die, ups and downs, forming die, flanging die, plastic mould, etc. 2. A. according to process combination, a single process model in a press tour, just completed a die stamping process. B. composite modulus is only one station, in a press trip, in the same station at the same time to complete two or more than two servings of stamping process the mold. C. progressive die (also known as continuous mode) on the blank into the direction of, have two or more stations, in a press trip, in a different location on the successive completed two or more than two servings of stamping process the mold. 3, according to the processing of product classification method According to the difference of the product processing method, can be divided into moulds shearing die, bending die, drawing die, five categories, such as forming mold and the compression mould. A. punching and shearing dies, is a shearing action to complete the work, commonly used in the form of cutting die, blanking die, punching die, the trimming die, the whole edge die cutting, hole punching and die cutting mould. B. bending die: is the smooth hair embryo bent into the shape of an Angle, depending on the shape of the parts, precision, and the amount of production, but there are many different forms of mold, such as ordinary bending die, bending die CAM, crimping die seam, circular arc bending die, bending die and die, etc. C. and drawing die, drawing die is made a bottom seamless container MAO embryo on the plane. D. forming mold: refers to through a variety of local deformation method to change the shape of hair embryo, its form has raised a forming die, roll edge forming die, necking forming die, hole flange forming die, flange forming die.
