The invention relates to a rapid die changing mechanism which comprises a die shell, a die ,a first connecting hole is formed in the die shell, a second connecting hole is formed in the die, a connecting piece passes through the first and second connecting holes. The connecting piece comprises a first part and a second part, the die shell is connected to the first part fixedly, the die is connected to the second part in a removable mode, the maximum width of the second part is less than or equal to the second connecting hole aperture, a boss is formed at the wall of the second connection hole towards its center, the outermost edge of one side of the second part of the connecting piece against the boss, is connected to the boss or closer to the axis of the second part , compared to the boss. A locking piece being connected to the outer end of the second part rotates around a rotation axis, when the locking piece blocks the boss at the outside of the boss, the die is positioned relative to the die shell, when the locking piece keeps away from the boss, the die can move along the direction of the axis of the second part of the connecting piece to depart from the die shell, so that the die can be disassembled. |
