The diameter of 1 increases in the clockwise direction. The six sides of the hexagonal lower mold 1 are respectively fixed with first labels 3 corresponding to the six lower mold bases 7. The first labels 3 can facilitate personnel to quickly check the models of the upper and lower annular protrusions 71 of the lower mold base 7. The middle part of the hexagonal upper mold 4 is sleeved and fixed on the upper rotating shaft 5. The bottom of the hexagonal upper mold 4 is fixedly connected to the upper mold base 9 by the second fastening bolt 10. The bottom of the upper mold base 9 is fixedly provided with an upper annular protrusion 91. The upper annular protrusion 91 on the upper mold base 9 surrounds the upper mold. There are three seats 9 arranged in a circular array at the center, and six upper die seats 9 at the bottom of the hexagonal upper die 4 are arranged in a circular array. The upper annular protrusions 91 on the six upper die seats 9 increase in size in a clockwise direction. By cooperating with the six groups of lower annular protrusions 71 of different sizes and the upper annular protrusions 91, the side sealing processing of six types of button batteries can be realized, which is more practical. The six sides of the hexagonal upper die 4 are respectively fixed with second labels 6 corresponding to the six upper die seats 9. The second labels 6 can facilitate personnel to check the upper die seats 9. A quick check of the model of the upper annular protrusion 91 shows that the upper mounting groove 41 is compatible with the corresponding upper annular protrusion 91 above it. When processing the side seal of the button battery, a corresponding set of lower annular protrusions 71 and upper annular protrusions 91 can be selected according to the model of the button battery to be processed, and the hexagonal lower mold 1 and the hexagonal upper mold 4 can be manually rotated to move the lower annular protrusion 71 and the upper annular protrusion 91 to the front side. The button battery can be side-sealed by cooperating with the lower annular protrusion 71 and the upper annular protrusion 91.
