The upper die 1 further comprises an upper cushion block 18 and an upper die plate 19, the upper cushion block 18 and the base body 11 are connected through bolts, the lower die 2 further comprises a lower cushion block 24 and a lower die plate 25, and the lower die plate 25, the lower cushion block 24 and the base 21 are connected through bolts.

In production, the operator completes the assembly of the upper mold 1 and the lower mold 2 (see fig. 3 and 6 for specific assembly structures), and then installs the assembly on the die cutting machine. Then, the product to be punched is placed into the forming cavity 22 through automatic feeding or manual operation of an operator, and then the upper die 1 and the lower die 2 are closed by the punching machine. When the die is closed, the cutter 12 contacts with the side wall of the product firstly, the side wall of the product is cut, after the cutting, the cutter 12 moves downwards continuously to cut the side wall of the product continuously, then the cutter 12 punches out from the bottom of the product and is inserted into the punching hole 27 to separate the bottom of the product, then the blade 13 contacts with the step 23 to cut off the residual joint of the side wall of the product, and the action of punching the side hole is completed. Through the steps, the punching of the side holes of the product can be completed only by one-time punching action, the processing steps are simple and high in efficiency, and the die only needs to complete one action, so that the whole structure is simpler.

It should be understood that the present invention is not only applicable to the product of fig. 1, but also to the product with triangular or quadrangular cross section, etc. when the product with tapered side wall and needing punching similar side hole is produced, the base body 11 and the forming cavity 22 can be replaced by the same shape, which can be easily converted by the person skilled in the art.
