Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0033] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: a new type of multi-layer combined stamping die, including a base 1, a lower die base 2 is fixedly connected to the upper surface of the base 1, the lower die base 2 is used for installing a lower die sleeve 18, a support column 3 is fixedly connected to the upper surface of the base 1, an upper die base 4 is fixedly connected to the upper surface of the support column 3, a hydraulic rod 5 is fixedly connected to the upper surface of the upper die base 4, the hydraulic rod 5 is used to push the stamping template 15 downward, the output end of the hydraulic rod 5 is fixedly connected to a mounting plate 6, the mounting plate 6 is used for installing the stamping template 15, a sliding rod 7 is slidably connected inside the mounting plate 6, a pull handle 8 is fixedly connected to the upper surface of the sliding rod 7, a fixed ring 10 is fixedly connected to the side wall of the sliding rod 7, a first spring 9 is sleeved on the side wall of the sliding rod 7, a fixed sleeve 11 is fixedly connected inside the mounting plate 6, a fixed rod 12 is fixedly connected inside the fixed sleeve 11, a sliding block 13 is slidably connected to the side wall of the fixed rod 12, the sliding block 13 is used for installing and connecting the stamping template 15, a rotating bar 14 is rotatably connected to the side wall of the sliding block 13, the rotating bar 14 is used to pull the sliding block 13, one end of the rotating bar 14 is rotatably connected to the side wall of the fixed ring 10, the side wall of the sliding rod 7 is slidably connected inside the fixed sleeve 11, a lower die sleeve 18 is fixedly connected to the upper surface of the lower die base 2, the lower die sleeve 18 is used for placing workpieces, a stamping template 15 is arranged on the lower surface of the mounting plate 6, the stamping template 15 is used for extruding workpieces, a mounting sleeve 16 is fixedly connected to the upper surface of the stamping template 15, the side wall of the sliding block 13 is slidably connected inside the mounting sleeve 16, a positioning component is arranged on the side wall of the stamping template 15 to prevent the die from shifting, one end of the first spring 9 is fixedly connected inside the mounting plate 6, and the other end of the first spring 9 is fixedly connected to the side wall of the fixed ring 10. The positioning component includes a positioning block 17, the side wall of the positioning block 17 is fixedly connected to the upper surface of the stamping template 15, a positioning sleeve 19 is fixedly connected to the side wall of the lower die sleeve 18, and the side wall of the positioning block 17 is slidably connected inside the positioning sleeve 19. The die can be positioned through the cooperation of the positioning block 17 and the positioning sleeve 19;
[0034] During the process of operating the device for production operations, first, the workpiece to be processed needs to be placed at the designated position on the lower die sleeve 18. Then, the operator needs to start the hydraulic rod 5. Driven by the hydraulic system, the hydraulic rod 5 pushes the stamping template 15 downward to perform an extrusion molding operation on the workpiece. During the downward movement of the stamping template 15, the positioning block 17 will automatically slide into the interior of the positioning sleeve 19 to ensure that it remains fixed in the correct position. Such a positioning mechanism can effectively prevent the problem of poor workpiece forming effect caused by the offset of the die during the stamping process. In addition, when it is necessary to replace the stamping template 15 to meet the processing requirements of different workpieces, the operator first needs to pull up the lifting handle 8. Using the principle of mechanical transmission, the sliding rod 7 is driven to move upward. During the upward movement of the sliding rod 7 inside the fixed sleeve 11, with the assistance of the fixed ring 10, the rotating bar 14 is pulled, causing the sliding block 13 to disengage from the mounting sleeve 16. At this time, the first spring 9 will contract under the action of pressure, thus providing convenient conditions for removing and replacing the stamping template 15. Through this series of precise and orderly operation steps, it can be ensured that the device is both fast and efficient during the process of replacing the stamping template 15, thereby improving the overall production efficiency.
[0035] Refer to Figure 2 and Figure 5 , a mounting seat 21 is fixedly connected inside the base 1. A sliding block 23 is slidably connected inside the mounting seat 21. A fixing plate 27 is fixedly connected to the side wall of the sliding block 23. A top column 28 is fixedly connected to the upper surface of the fixing plate 27. The side wall of the top column 28 penetrates through the lower die sleeve 18 and is fixedly connected to a top plate 20. The workpiece can be ejected through the cooperation of the top column 28 and the top plate 20. The side wall of the top plate 20 is slidably connected inside the lower die sleeve 18. A second spring 22 is arranged inside the mounting seat 21. The second spring 22 is used to push the sliding block 23 to slide. One end of the second spring 22 is fixedly connected inside the mounting seat 21, and the other end of the second spring 22 is fixedly connected to the side wall of the sliding block 23. A fixing block 25 is fixedly connected inside the mounting seat 21. A rotating rod 26 is rotatably connected to the side wall of the fixing block 25. The rotating rod 26 is used to hold the sliding block 23. A card slot 24 is formed inside the sliding block 23. The side wall of the rotating rod 26 is slidably connected inside the card slot 24.
[0036] During the process of stamping the workpiece, due to the extrusion force applied to the workpiece, the top plate 20 is subjected to pressure, which causes the top plate 20 to move downward under the action of the pressure. As the top plate 20 moves downward, the ejector pin 28 is also driven to move downward accordingly. The downward movement of the ejector pin 28, supported by the fixing plate 27, enables the sliding block 23 to slide on the sliding track. The sliding movement of the sliding block 23 is further transmitted to the rotating rod 26, causing the rotating rod 26 to be pressured inside the clamping groove 24, and thus to perform a corresponding sliding movement under the constraint of the clamping groove 24. This sliding movement effectively releases the fixed state of the sliding block 23, allowing the sliding block 23 to move. When the stamping template 15 starts to move upward after the stamping process is completed, since the sliding block 23 has lost its previous fixed state, the second spring 22 begins to exert its resilience. The resilience of the second spring 22 causes the sliding block 23 to move upward accordingly, which in turn drives the ejector pin 28 to push the top plate 20 upward, causing it to also move upward. The upward movement of the top plate 20 enables the workpiece inside the lower die sleeve 18 to be ejected, thus achieving the effect of rapid demolding. The coordinated cooperation of this series of actions ensures the smooth progress of the entire stamping process, and also improves the production efficiency and the quality of the workpiece.
[0037] Working principle: When using this equipment for work, place the workpiece on the lower die sleeve 18, and then start the hydraulic rod 5 to push the stamping template 15 downward to extrude and form the workpiece. During the downward pressing process, the positioning block 17 slides into the positioning sleeve 19 to achieve the positioning effect and prevent the mold from shifting during the downward pressing process, which may affect the extrusion effect of the workpiece. When it is necessary to replace the stamping template 15, first pull up the lifting handle 8 to drive the sliding rod 7 to move upward, so that the sliding rod 7 moves upward inside the fixed sleeve 11. Pull the rotating bar 14 through the fixing ring 10 to disengage the sliding block 13 from the mounting sleeve 16, causing the first spring 9 to be pressured and contract, and then the stamping template 15 can be removed for replacement. During the stamping process of the workpiece, due to the extrusion of the workpiece, the top plate 20 is extruded and moves downward, causing the ejector pin 28 to move downward. Through the fixing plate 27, the sliding block 23 slides, causing the rotating rod 26 to be pressured and slide inside the clamping groove 24, thus releasing the fixation of the sliding block 23. When the stamping template 15 moves upward, since the sliding block 23 loses its fixation, the second spring 22 rebounds, pulling the sliding block 23 upward, causing the ejector pin 28 to push the top plate 20 upward, and thus ejecting the workpiece inside the lower die sleeve 18 to achieve the effect of rapid demolding.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
