The invention relates to a coiling mould which is used for coiling and molding workpieces and comprises an upper die, a transmission body and a lower die. The upper die comprises an upper die body, a first pressing block and a first bearing body; wherein the first pressing block is used for warping and bending the workpieces and fixing the workpieces on the upper die body; the first bearing body is matched with the first pressing block and is used for putting the workpieces. The transmission body comprises a first socket which is opposite to the upper die and a second die which is positioned on one side which is back to the first socket. The lower die comprises a lower die body which has a third socket and a fourth socket, a second pressing block which is used for coiling the workpieces and fixing the workpieces on the second socket, a third pressing block which is used for pressing the workpieces and fixing the workpieces on the transmission body, and a second bearing body which is corresponding to the second pressing block and is used for putting the workpieces. The first bearing body is fixed inside the first socket of the transmission body; the second bearing body is fixed inside the fourth socket of the lower die body; the transmission body is connected inside the third socket of the lower die body in a sliding way.
