[0120] When the upper die assembly 200 is docked with the lower die assembly 100, referring to Figure 23 , the extending arm 211 abuts against the turnover plate 410, so that the turnover plate 410 is located at the rear side of the upper die assembly 200, and the torsional spring 440 is in a compressed state.

[0121] When the upper die assembly 200 moves upward, referring to Figure 24 , with the continuous rising of the upper die assembly 200, the extending arm 211 is separated from the turnover plate 410, and the turnover plate 410 is turned over to the lower side of the upper die assembly 200 under the action of the torsional spring 440.

[0122] When the upper die assembly 200 moves downward, with the continuous descending of the upper die assembly 200, the lower end of the extending arm 211 contacts the turnover plate 410 and pushes the turnover plate 410 to reset.

[0123] The turnover plate 410 does not need to be provided with a driving mechanism, and the turnover action of the turnover plate 410 is realized by using the torsional spring 440 and in combination with the lifting action of the upper die assembly 200, so that the cost is low and the structure is reliable.
