Usually, molds are composed of two types of parts:

One type is process parts, which directly participate in the completion of the process and have direct contact with the blank, including working parts, positioning parts, discharging and pressing parts, etc.

one kind is the structural parts, which do not directly participate in the completion of the process, nor have direct contact with the blank, but only play a role in ensuring the completion of the process or improving the function of the mold, including guiding parts, fastening parts, standard parts and other parts, as shown in table 1.1.3. It should be pointed out that not all stamping dies must have the above six parts, especially single-process dies, but working parts and necessary fixed parts are indispensable.
