DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4, a stamping die for supporting bosses on an inner cavity plate, comprising a bottom plate 1, two hydraulic rods 2 are fixedly connected to the bottom plate 1, connecting frames 3 are fixedly connected to the two hydraulic rods 2, an upper die 16 is fixedly connected between the two connecting frames 3, a plurality of protrusions 17 are connected to the upper die 16 through a detachable mechanism, a plurality of lower dies 4 are placed on the bottom plate 1, a plurality of lower dies 4 are provided with forming grooves 9, the forming grooves 9 on each lower die 4 have different spacings, a plurality of lower dies 4 are moved by a moving mechanism, the protrusions 17 can enter the forming grooves 9, the lower dies 4 are moved by the moving mechanism, the lower dies 4 of different specifications are moved to the bottom of the upper die 16, and the position of the protrusions 17 is moved, or the number of the protrusions 17 is increased or decreased, so that the protrusions 17 cooperate with the forming grooves 9 during stamping to form bosses of different numbers, and the distance between the forming bosses is changed to produce bosses with different spacings, thereby improving the applicability of the die.

[0021] The detachable mechanism includes a connecting block 6, both ends of the protrusion 17 are fixedly connected to the connecting block 6, the two connecting blocks 6 are threaded with bolts 7, the upper mold 16 is fixedly connected to a connecting edge 5, the bolts 7 abut against the connecting edge 5, and the connecting edge 5 is disassembled by using the bolts 7 to change the position of the protrusion 17 or the number of the protrusions 17.

[0022] An abutment block 8 is fixedly connected to the bolt 7. When the bolt 7 is used for fixed abutment, it is beneficial to increase the contact area and prevent damage to the connecting edge 5. Anti-slip grooves are provided on both sides of the connecting edge 5, which is beneficial to increase the friction during fixation and prevent loosening.
