[0014] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0015] refer to Figure 1-2 As shown, the utility model provides a split packing box die, including: a first tooth body 1 and a second tooth body 2, the first tooth body 1 and the second tooth body 2 are semicircular ring structures of the same size, the inner circle sides of the first tooth body 1 and the second tooth body 2 are both provided with cutting edges 3 and chip grooves 4, the middle parts of the outer circle sides of the first tooth body 1 and the second tooth body 2 are both welded with nuts 5, the first hollow circular tubes 6 are both welded at both ends of the outer circle side of the first tooth body 1, the second hollow circular tubes 7 are both welded at both ends of the outer circle side of the second tooth body 2, and the first hollow circular tubes 6 and the second hollow circular tubes 7 are fastened by bolts. The first tooth body 1 and the second tooth body 2 are made of 45# carbon steel, and the cutting edges 3 are processed according to the external threads of the packing box.

[0016] As a preferred embodiment, the interior of the first hollow circular tube 6 is tapped with internal threads, and the interior of the second hollow circular tube 7 is a smooth through hole.

[0017] The working process and principle of the utility model are:

[0018] When in use, align the first tooth body 1 and the second tooth body 2 on both sides of the external thread of the packing box, then fix the relative position of the first hollow circular tube 6 and the second hollow circular tube 7 by high-strength bolts, and finally install the push rod with an external thread on the end into the nut 5. The die is rotated by the push rod to repair the external thread of the packing box.
