Automobile mould basic overview

The most important part of automobile die is covering mould. This kind of mold is mainly cold stamping die. Generalized "automobile die manufacturing car" is all the parts. For example, stamping die, injection mold, forging mold, casting wax mold, glass mold etc..
On vehicle body stamping generally divided into panels, beams and general stamping parts. Can obviously said stamping car image feature is the auto cover. Therefore, auto mould more specified can be said to be "stamping die of automobile cover". Referred to as the stamping die for automobile covering. For example, the front door outer plate trimming die, front door inner plate punching die.
Of course, the car is not only the body of stamping part. Mold car all stamping parts are called "automotive stamping die". The summary is:
1 auto mould made cars on all parts of the mold.
2 automotive stamping die stamping die for automobile is all stamping.
3 car body stamping die stamping die for automobile body is all stamping.
4 automobile panel stamping mould is die all covering parts of car body.
Now we say this plate automobile mould seemed refers to die of automobile covering parts. In order to automobile die with generalized confusion, in the post the best use of automobile panel die instead of automobile die.
A lot of stamping die, die also depend on the nature of the work, die structure, die material three to classification.
According to the general classification of the following main characteristics:
1 according to the technical nature of the classification
A. blanking die: along the contour of the closed or open the mold separation of the material produced. Such as blanking die, punching die, cutting die, cutting die, blanking die, cutting die and so.
The B. bending mode: the blank or blank sheet along a straight line (curve) of bending deformation, mould parts and thus obtain a certain angle and the shape of the.
C. drawing die: the blank sheet opening hollow, or hollow pieces of further change the shape and size of the die.
D. forming die: is rough or semi-finished workpiece drawing convex, concave die forming the shape of a direct copy, and the material itself produces only local plastic deformation of the mold. Such as bulging die, the die shrink, flaring die, forming die rolling, flanging die, plastic mold.
2 according to the degree classification process combination
A. single process mode: in a press tour, only to complete the mold a punching process.
B. compound die: only one station, in a press tour, finish the mould two or two servings of punching process at the same time on the same station.
C. progressive die (also known as the modulus of continuity): in the blanks sent to direction, with two or more stations, in the press of a trip, completed mold two or two servings of punching process at different stations.
3, according to the classification of products processing method
According to the different processing methods, the mold can be divided into punching die, bending die, drawing die, mold and compression mold and other five categories.
A.: die is to finish the work by the shearing action, common form of cutting die, blanking die, punching, trimming die, trimming die, drawing die and punching die hole.
B. bending die: is the smooth hair 胚弯 into a point shape, as the shape of the parts, precision and the production quantity, but there are many different forms of mold, such as ordinary bending die, bending die, flanging die cam, arc bending die, bending and twisting die, die punch fracture.
C. drawing die: drawing die is made of a seamless container flat blank.
D.: refers to the method of forming die with various local deformation to change the blank shape, in the form of a convex sheet forming die, molding die, roll edge necking forming die, hole flanging die, flange forming die.
E. compression mold: is the use of strong pressure, so that the metal blank flow deformation, into a desired shape, there are the types of extrusion die, stamping die, stamping die, end the embossing die。
