[0013] However, if countless recesses 112 are processed on the forming surface 111 of the lower mold 110, the processing cost will increase, and the mold will be extremely expensive.
Therefore, the countermeasure is difficult to adopt

Embodiment
[0045] Such as figure 1 As shown, the stamping die 10 includes a lower die 12 supported by a backing plate 11 , an upper die 14 supported by an upper frame 13 , and a pressing plate 15 pushing a blank to the upper die 14 .
[0046] In addition, the structure of the press machine which operates the press die 10 can be selected suitably. That is, the upper die 14 can be moved up and down with the lower die 12 stationary, the lower die 12 can be raised and lowered with the upper die 14 stationary, or the lower die 12 and the upper die 14 can be moved up and down together. In a word, as long as the upper mold 14 and the lower mold 12 move relatively.
[0047] Such as figure 2 As shown, in order to form the specific portion, the lower specific portion forming portion 17 is partially integrally formed on the lower mold 12 . In this example, the lower specific portion forming portion 17 protrudes upward from the general surface (general molding surface) 18 of the lower mold 12 ....

The invention relates to a stamping mould and a deep drawing product and provides a structure capable reducing the cost of the mould while not leaving a concavo-convex trace at a specific position of the stamping mould. The stamping mould draws material (26) with a bottom mould (12) and a top mould (14). In the meantime, a specific position (30) is formed by drawing a bottom specific position forming portion (17) and a top specific position forming portion (21). Foreign matters (28) attached to the bottom surface are contained in the dodge portion (19) at the bottom mould (12) or is dropped. Foreign matters (27) attached to the top surface are contained in the dodge portion (23) at the top mould (12). As a result, it is no need in worrying about that the foreign matters (27, 28) enter the specific position (30). The stamping mould is formed by just by disposing the bottom specific position forming portion and the top specific position forming portion on the specific portion and is capable of suppressing the increase in the cost of the stamping mould.
Description
technical field [0001] The invention relates to a stamping die capable of integrally forming a specific part capable of printing or engraving a product identification mark (such as a product management number) in a subsequent process on a deep-drawn product through deep-drawing. Background technique [0002] Figure 11 It is a perspective view of a conventional vehicle floor, and the vehicle floor 100 is obtained by drawing and trimming a blank with a press die, and trimming (trimming). [0003] Such as Figure 12 As shown, a product identification mark such as a product management number 101 is printed or engraved on the vehicle base plate 100 . This product management number 101 is used for follow-up investigations in subsequent processes or after shipment. [0004] However, foreign matter such as dust or iron powder may adhere to the billet during conveyance. Although cleaning is performed before deep drawing, foreign matter that cannot be removed may remain. When the ...
