Basic overview of automotive molds

DATE:2019-09-02 14:39:29 FROM:

The main component of automotive molds is the cover mold. This type of mold is mainly a cold die. The "automotive mold" in a broad sense is a general term for the molds that make all the parts on a car. For example, stamping dies, injection dies, forging dies, casting wax dies, glass dies, and the like.
Stampings on automotive bodies are broadly divided into cover members, beam members, and general stampings. A stamping that can clearly represent the characteristics of a car is a car cover. Therefore, the more specific automobile mold can be said to be "automotive cover stamping die". Referred to as the car cover die. For example, the front door outer panel trimming die, the front door inner panel punching die, and the like.
Of course, there are not only stampings on the car body. The molds for all stampings on the car are called “automotive stamping dies”. To sum it up is:
1. Automotive molds are the general term for molds that make all the parts on a car.
2. Auto stamping dies are molds that punch all the stampings on the car.
3. The car body stamping die is a die that punches all the stamped parts on the car body.
4. Car cover stamping die is a die that punches all the cover parts of the car body.
Now we say that the car mold seems to refer to the car cover die. In order not to be confused with the generalized car die, it is better to use the car cover die without the car die when posting.
There are many forms of stamping dies, and the dies are classified according to the working properties, mold construction, and mold materials.
Generally classified by the following main features:
  1. Classified according to process properties
a. Blanking die: A separate mold is created along a closed or open contour. Such as blanking die, punching die, cutting die, slit die, trimming die, cutting die and so on.
b. Bending mold: A mold for bending a sheet blank or other blank along a straight line (curved line) to obtain a workpiece of a certain angle and shape.
c. Drawing die: A mold that makes a blank of sheet material into an open hollow piece or that further changes the shape and size of the hollow part.
d. Forming die: It is a mold that directly replicates the shape of 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 die, shrinking die, flaring die, undulating forming die, flanging die, shaping die and the like.
  2. Classified according to the degree of process combination
a. Single-step mold: In one stroke of the press, only one mold of the stamping process is completed.
b. Composite mold: There is only one station, and in the one stroke of the press, two or more stamping processes are simultaneously completed at the same station.
c. Progressive die (also called continuous die): There are two or more stations in the feeding direction of the blank, and two or two successively in different positions in the press. The mold of the stamping process above the road.
3. Classification according to the processing method of the product
Depending on the processing method of the product, the mold can be divided into five categories: punching and cutting die, bending die, drawing die, forming die and compression die.
a. Punching and cutting die: It is done by shearing. Commonly used forms include shearing die, blanking die, punching die, trimming die, whole edge die, hole punching die and punching die.
b. Bending mold: It is a shape that bends the flat blank into an angle. Depending on the shape, precision and production volume of the part, there are many different types of molds, such as ordinary bending dies, cam bending dies, and crimping. Dies, arc bending dies, bending punch dies and twisting dies.
c. Draw mold: The draw mold is a flat blank container made of flat blanks.
d. Forming Mold: refers to changing the shape of the blank by various local deformation methods, in the form of a convex forming die, a curl forming die, a neck forming die, a hole flange forming die, and a round edge forming die.
e. Compression mold: It uses strong pressure to deform the metal blanks into the desired shape. The types include extrusion dies, embossing dies, embossing dies and end dies.
