Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] See also Figures 1 to 5 In one aspect, an embodiment of the present application discloses a waste discharge structure, which is arranged between an upper die 1 and a lower die 2 of a stamping die, wherein the waste discharge structure includes a discharge assembly and a drive assembly.

[0043] See also Figures 1 to 5 The discharge assembly includes a movable plate 110 and a connecting rod 120. The connecting rod 120 is arranged horizontally, and the connecting rod 120 is movably connected to a plurality of movable plates 110. The movable plate 110 is arranged in the waste collection chamber of the continuous mold, and the movable plate 110 is rotatably connected to the connecting rod 120, that is, the movable plate 110 can rotate with the connecting rod 120 as the rotation axis.

[0044] See also Figures 1 to 5The driving assembly includes a driving block 210, a rotating gear 220, a driving rack 230, a connecting rack 240, a reset mechanism 250 and a guide mechanism 260. The driving block 210 is mounted on the upper mold 1; the rotating gear 220 is rotatably mounted on the lower mold 2; the driving rack 230 and the connecting rack 240 are respectively meshed and connected with the rotating gear 220; one end of the connecting rod 120 is rotatably connected with the connecting rack 240; the reset mechanism 250 is used to drive the connecting rack 240 to reset; the driving block 210 is located on the extended side of the driving rack 230; the driving block 210 drives the connecting rack 240 to move by driving the rack 230 and the rotating gear 220; the guide mechanism 260 is used to provide guidance for the driving rack 230 and the connecting rack 240.

[0045] During the process of closing and opening the upper mold 1 and the lower mold 2 , the upper mold 1 drives the driving block 210 to reciprocate up and down.

[0046] In the process of the driving block 210 reciprocating up and down, the driving block 210 regularly hits the end of the driving rack 230 close to the driving block 210, and the driving block 210 can push the driving rack 230 to move in the direction close to the lower mold 2. At this time, the driving rack 230 drives the rotating gear 220 to rotate through the meshing relationship, and the rotating gear 220 drives the connecting rack 240 to move, so that the connecting gear drives the connecting rod 120 to move. Driven by the connecting rod 120, the movable plate 110 also reciprocates with the connecting rod 120. In the process of the reciprocating movement of the movable plate 110, the waste falling on the movable plate 110 is pushed to the side away from the connecting rod 120, so as to achieve the purpose of discharging the waste.

[0047] When the upper mold 1 moves in a direction away from the lower mold 2, the driving block 210 separates from the driving rack 230, and under the action of the reset mechanism 250, the connecting rack 240 moves in the opposite direction (i.e., in the direction close to the connecting rod 120), and the connecting rack 240 drives the rotating gear 220 to rotate, and the rotating gear 220 drives the driving rack 230 to move in a direction close to the upper mold 1.

[0048] When the upper die 1 moves toward the direction approaching the lower die 2, the above-mentioned actions are repeated.

[0049] In the embodiment of the present application, by utilizing the relative movement of the upper mold 1 and the lower mold 2 to drive the connecting rod 120 and the movable plate 110, the waste can be forcibly shaken out of the movable plate 110 to achieve the purpose of waste discharge, so that there is no need to stop the mold production process, which is beneficial to greatly improve production efficiency.

[0050] In some embodiments of the present application, the guide mechanism 260 includes a first guide groove and a second guide groove, the driving rack 230 is slidably engaged with the first guide groove, and the connecting rack 240 is slidably engaged with the second guide groove.

[0051] It should be understood that the first guide groove and the second guide groove are offset from each other so that no interference occurs between the driving rack 230 and the connecting rack 240 .

[0052] In some embodiments of the present application, see Figure 4 and Figure 5 The guide mechanism 260 includes a first component 261 and a second component 262 which are stacked, a first guide groove is provided in the first component 261, and a second guide groove is provided in the second component 262.
