Classification according to the degree of process combination
(1) Single-process mold In one stroke of the press, only one stamping process mold is completed.
(2) Compound mold There is only one station. In one stroke of the press, two or more stamping processes can be completed at the same time on the same station.
(3) 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.
(4) The transfer mold combines the characteristics of single-process mold and progressive mold. The robot transfer system is used to realize the rapid transfer of the product in the mold, which can greatly improve the production efficiency of the product, reduce the production cost of the product, save the material cost, and quality Stable and reliable.
Classification according to the deformation characteristics of the material
Typical structure of mold:
Figure 1.1.2 is a single-process punching die with guide posts and guide sleeves. It is composed of upper and lower molds. The upper mold is composed of mold handle 5, upper mold seat 3, guide sleeve 2, punch 10, backing plate 8, fixing plate 7, discharge plate 14 and screws, pins and other parts; The mold is composed of a lower mold base 17, a guide post 1, a concave mold 11, a material guide plate 15, a material receiving plate 18, screws, pins and other parts. The upper die is installed on the press slider through the die handle 5 and reciprocates up and down with the slider, so it is called the movable part. The lower mold is fixed on the press table through the lower mold base, so it is also called the fixed part.
