The stamping parts on the car body are roughly divided into cover parts, beam parts and general stamping parts. The stamping parts that can clearly express the characteristics of the car's image are the car cover parts. Therefore, the automobile die that Gart refers to can be said to be a "automotive cover stamping die". Referred to as automotive panel die. For example, front door outer panel trimming die, front door inner panel punching die, etc.
Of course, there are not only stamped parts on the car body. All stamping dies on automobiles are called "auto stamping dies". In summary:
1. Auto mold is the general name of molds used to manufacture all parts of automobiles.
2. Automobile stamping dies are used to punch all stamping parts on automobiles.
3. Auto body stamping die is a die for punching all stamping parts on auto body.
4. Auto cover stamping die is a die for punching all cover parts on auto body.
Now when we talk about automobile molds in this sector, it seems to refer to the automobile cover die. In order not to be confused with the automobile die in a broad sense, it is better to use the automobile cover die instead of the automobile die when posting.
Molds used for vulcanization and molding of various types of tires.
Automobile tire mold classification:
1. The flexible mold is composed of pattern ring, mold sleeve, upper and lower side plates.
2. The two halves of the mold are composed of an upper mold and a lower mold.
Automobile tire mold processing technology (take the active mold as an example):
1. Cast or forge the blank according to the tire mold diagram, and then rough the blank and heat treatment. Tire mold blanks are annealed to eliminate internal stress. They should be laid flat during annealing to avoid excessive deformation.
2. Drill the hoisting holes according to the drawing, and then process the outer diameter and height of the pattern ring according to the semi-finished turning drawing. Use the semi-finished turning program to turn the inner cavity of the pattern ring, and inspect the semi-finished turning template after turning.
3. Use the processed tire mold pattern electrode to shape the inner pattern of the pattern ring by EDM, and use the model to test.
4. Divide the pattern circle into several parts according to the manufacturer's requirements, draw the marking lines respectively, and put them in the tooling to punch the back waist hole and tap the thread.
5. According to the equal parts divided in process 8, align and cut at the scribe line.
6. The cut pattern blocks are polished, corners, roots, and vent holes are drilled according to the requirements of the drawings.
7. Evenly blast sand inside the pattern block cavity, requiring consistent colors.
8. Combine the pattern ring, mold sleeve, upper and lower side plates to complete the tire mold.
