[0027] In this embodiment, by providing a spring-back mechanism 1, the parts placed inside the forming groove of the fixed mold 12 can be conveniently taken out. The top plate 13 is provided, and the top plate 13 is placed in the installation groove opened on the fixed mold 12. Therefore, the setting of the top plate 13 will not affect the stamping process of the parts by the moving mold 11 and the fixed mold 12. The first spring 16 is provided. By utilizing the characteristic that the first spring 16 generates elastic force when stretched, the top plate 13 has a large impact force when rebounding, and then the parts closely connected to the inner wall of the forming groove of the fixed mold 12 can be ejected. In addition, a guiding block 17 is provided to guide the sliding of the limiting piece 15. An arc surface 101 is opened on the fixed block 18, so that the fixed block 18 can extrude and adjust the bevel block 21, and the bevel block 21 can smoothly slide into the fixed mold 12.

[0028] Embodiment 2

[0029] As Figures 1 - 5 shown, a triggering mechanism 2 is provided inside the fixed mold 12. The number of the triggering mechanisms 2 is two. The triggering mechanism 2 includes a bevel block 21. The bevel block 21 penetrates through the fixed mold 12. The bevel block 21 is slidably connected to the fixed mold 12. One end of the bevel block 21 is fixedly connected with an extrusion piece 22. One side surface of the extrusion piece 22 is fixedly connected with a square rod 23. The square rod 23 penetrates through the fixed mold 12. The square rod 23 is slidably connected to the fixed mold 12. A second spring 24 is sleeved on the outer surface of the square rod 23. One end of the second spring 24 is fixedly connected to the outer surface of the extrusion piece 22. The other end of the second spring 24 is fixedly connected to the inner wall of the fixed mold 12. One end of the square rod 23 is fixedly connected with a pulling block 25.

[0030] In this embodiment, by providing the triggering mechanism 2, the use state of the spring-back mechanism 1 can be determined. By providing the bevel block 21, it can be used in cooperation with the bevel groove 19 and engage with the fixed block 18. At the same time, by providing the extrusion piece 22, the second spring 24 can be compressed by the extrusion piece 22, so that the second spring 24 generates elastic force. Then, the elastic force of the second spring 24 can reset the bevel block 21 and closely fit with the bevel groove 19 opened on the fixed block 18.

[0031] Working principle:

[0032] As Figures 1 - 5As shown in the figure, when the present utility model is in use, the top plate 13 can be reset first. At this time, press the top plate 13, and the top plate 13 will drive the limiting piece 15 to move downward synchronously by means of the connecting rod 14. Furthermore, the limiting piece 15 can stretch the first spring 16, so that the first spring 16 generates sufficient elastic force. At the same time, the fixed block 18 will also move downward under the drive of the top plate 13, and the fixed block 18 will squeeze the bevel block 21 by means of the arc surface 101 during the movement, so that the bevel block 21 slides into the fixed mold 12. At this time, when the bevel block 21 slides, it will compress the second spring 24 by means of the pressing piece 22, so that the second spring 24 generates elastic force. When the top plate 13 completely enters the installation groove opened on the fixed mold 12, the extrusion restriction on the bevel block 21 will disappear instantly. Furthermore, the elastic force of the second spring 24 will be released, and the pressing piece 22 and the bevel block 21 will be reset. The bevel block 21 will tightly engage into the bevel groove 19 opened on the fixed block 18 under the action of the elastic force of the second spring 24. Then, the processing of parts can be carried out. Place the blank plate on the top of the forming groove opened on the fixed mold 12. At this time, the moving mold 11 will be tightly attached to the fixed mold 12 under the drive of the stamping machine, and the blank plate will be stamped while being attached, so that the part enters the forming groove. If the edge of the part fits tightly with the inner wall of the forming groove, making it impossible to take out the part by the established material taking means, the pull block 25 can be pulled first. The pull block 25 will drive the square rod 23 to slide. Furthermore, under the drive of the square rod 23, the bevel block 21 will be separated from the fixed block 18. At the same time, the elastic force of the first spring 16 will be released instantly when the bevel block 21 is separated from the fixed block 18, and the limiting piece 15, the connecting rod 14 and the top plate 13 will be driven, so that the top plate 13 can eject the part with a strong impact force, and then the work of taking out the part is completed.

[0033] The above is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
