The top of the lower die 4 is fixedly connected to the shell 5, and a blanking assembly is arranged at the rear end inside the shell 5. After the stamping is completed, when the upper die 2 moves upward, the blanking assembly clamps the finished product to prevent the finished product from being stuck on the upper module 10. A transmission assembly is arranged at the front end inside the shell 5. A fixed rod 13 is fixedly connected to the middle end of the bottom of the upper die 2, and the bottom of the fixed rod 13 is threadedly connected to the upper module 10. The upper module 10 can be removed for replacement of other mold blocks. The right end of the bottom of the upper die 2 is rotatably connected to a spiral rod 14. The spiral rod 14 has only a thread at the bottom and is longitudinal, and the thread density is small. When it moves downward, it can enter from the hole opened at the top of the shell 5, driving the bevel gear 20 below the hole to rotate.

[0024] The transmission assembly includes a threaded rod 16 located inside the housing 5. The front end of the threaded rod 16 penetrates the housing 5. Two bevel gears 20 are provided at the front end inside the housing 5. The two bevel gears 20 are meshed and connected, and the two bevel gears 20 are both rotatably connected to the inner wall of the housing 5. When the bevel gear 20 rotates, it drives the pulley 15 to rotate, and then drives the threaded rod 16 to rotate through the pulley 15. The blanking assembly includes a bidirectional screw 17 located at the rear end inside the housing 5. The left end of the bidirectional screw 17 is fixedly connected to the top of the lower mold 4. The right end of the bidirectional screw 17 and the rear end of the threaded rod 16 are fixedly connected with a bevel gear 19, and the two bevel gears 19 are meshed and connected. When the threaded rod 16 rotates, it drives the bevel gear 19 to rotate, and the bevel gear 19 drives the bidirectional screw 17 to rotate. The right end bevel gear 19 is rotatably connected to the inner wall of the housing 5. The disassembly and assembly assembly includes a lower module 9 located at the middle end of the lower die 4, the lower module 9 is slidably connected in the groove 6, a mold groove is provided on the top of the lower module 9, and two fixing piles 11 are fixedly connected to the rear end of the top of the lower module 9, and the fixing piles 11 can limit the plate to be stamped, and the bottom sides of the lower module 9 are fixedly connected with mounting strips. The fixing assembly includes a fixing plate 7 located at the front end of the lower module 9, and the fixing plate 7 is connected to a clamping block 12 by bolts 8. The clamping block 12 is slidably connected in the groove 6, and the clamping block 12 and the fixing plate 7 are clamped by tightening the nut, so as to limit the lower module 9. The front end of the bevel gear 20 and the front end of the threaded rod 16 are fixedly connected with a pulley 15, and the two pulleys 15 are connected by a belt. Through the transmission of the two pulleys 15, the bevel gear 20 can drive the threaded rod 16 to rotate. The outer wall of the bidirectional screw 17 is threadedly connected with two clamping plates 18. When the bidirectional screw 17 rotates, the clamping plates 18 will simultaneously move toward the middle of the bidirectional screw 17 to clamp the finished product.

[0025] Working principle: first rotate the upper module 10 and tighten it with the fixing rod 13, then insert the mounting strip fixedly connected to the bottom of the lower module 9 into the groove 6 on the bottom side of the inner middle end of the lower mold 4, then insert the clamping block 12 at the bottom of the fixing plate 7 into the groove 6 and tighten the fixing plate 7 and the clamping block 12 through the bolt 8, so as to limit the lower module 9 and make it unable to move. When the upper mold 2 moves downward, the screw rod 14 at the bottom of the upper mold 2 will move downward at the same time, and the screw rod 14 will be inserted from the hole at the top of the shell 5. At this time, the screw rod 14 will drive the bevel gear 20 at the top of the shell 5 to rotate, and the other bevel gear 20 meshing with it will also rotate. The bevel gear 20 will rotate, and the bevel gear 2 will drive the pulley 15 at the front end of the housing 5 to rotate. The pulley 15 drives another pulley 15 through the belt, thereby driving the threaded rod 16 fixedly connected to the pulley 15 to rotate. The threaded rod 16 then drives the bevel gear 19 to rotate, and another bevel gear 19 meshing with the bevel gear 19 will rotate at the same time. Since the bidirectional screw 17 is fixedly connected to the bevel gear 19, the bevel gear 19 will drive the bidirectional screw 17 to rotate. At this time, the clamping plate 18 on the outer wall of the bidirectional screw 17 will approach to the middle, thereby clamping the stamped finished product, separating the finished product from the upper module 10, so as to achieve the effect of automatic falling off of the finished product.
