[0024] Stamping groove 2 top is equipped with stamping die 4, cylinder 3 is installed on fixed frame 1, cylinder 3 is connected with stamping die 4 by movable mechanism, fixed frame 1 is equipped with fixed box 7 by support column 6, fixed box 7 is equipped with baffle 10 corresponding with stamping die 4, fixed box 7 is equipped with rotating cavity 16 and lifting cavity 17, screw rod 18 is arranged in rotating cavity 16, rotating shaft 12 connected with screw rod 18 is arranged on fixed frame 1, piston plate 19 is sealingly slidably arranged in lifting cavity 17, piston plate 19 is connected with screw rod 18 by link mechanism, fixed box 7 is also equipped with water inlet pipe 8 and nozzle 9, fixed box 7 is equipped with driving gear 15 by support plate 13, driving gear 15 is connected with rotating shaft 12 by transmission mechanism, cylinder 3 is connected with driving gear 15 by rotating mechanism.

[0025] Movable mechanism includes limit ring 23 arranged on the output shaft of cylinder 3, fixed sleeve 5 corresponding with limit ring 23 is arranged on stamping die 4, spring 24 is arranged on the outer part of the output shaft of cylinder 3, and the both ends of spring 24 are elastically connected with the outer wall of limit ring 23 and fixed sleeve 5 respectively. The elastic potential energy of spring 24 is sufficient to ensure that the output shaft of cylinder 3 is in contact with stamping die 4 in daily state.

[0026] The connecting mechanism comprises a connecting frame 20 threaded on the screw rod 18, and the end of the connecting frame 20 is fixedly connected with the piston plate 19. The connecting frame 20 is designed in a U shape, and the vertical part thereof is slidably penetrated through the bottom wall of the rotating cavity 16 and extends into the lifting cavity 17, so that the connecting frame 20 is limited and cannot rotate with the screw rod 18.

[0027] The transmission mechanism comprises transmission gears 14 installed on the support plate 13 and the rotating shaft 12, and the two transmission gears 14 are vertically engaged. As shown in the figure, the transmission gears 14 are conical gears, and a horizontal shaft is horizontally and rotatably installed on the support plate 13, and the driving gear 15 and the transmission gears 14 are connected with the horizontal shaft.

[0028] The rotating mechanism comprises a rack frame 11 installed on the output shaft of the air cylinder 3, and the rack frame 11 is arranged in cooperation with the driving gear 15. The rack frame 11 can be lifted under the action of the air cylinder 3, and the lifting process can drive the driving gear 15 to rotate.

[0032] When the stamping die 4 rises, the stamping die 4 contacts the baffle 10, and the rack frame 11 has not contacted the driving gear 15 at this time. In the subsequent rising process, since the stamping die 4 is blocked by the baffle 10, the extension end of the air cylinder 3 continuously rises to compress the spring 24 at this time, and then the rack frame 11 continuously rises, so as to drive the driving gear 15 to reverse rotation. At this time, the piston plate 19 will descend, and the water in the lifting cavity 17 will be sprayed out to the surface of the stamping die 4 through the nozzle 9 to perform the cooling operation. The excess water drops into the stamping groove 2, if the formed product is not taken out at this time, the cooling of the product and the stamping groove 2 can be performed, and finally the excess water is collected into the collecting cavity 21 through the water falling hole 22.
