[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] After searching, the patent application number is (202020105596.2), which discloses "a stamping die that is convenient for picking up products", which solves some drawbacks of the existing stamping die that is convenient for picking up products. When the die head is stamping on the inner side of the lower stamping template, the die head is not easy to detach from the inner side of the lower stamping template. In addition, after the die head is used for a long time, the surface is severely worn and it is inconvenient to replace. For this reason, we propose a stamping die that is convenient for picking up products;

[0004] However, the above device has the following problems: after completing the stamping operation, the stamping die of the prior art often needs to be manually removed from the die. However, the manual removal method is very dangerous under this stamping equipment, which neither meets the requirements of safe production nor improves production efficiency. For this reason, we propose a stamping shaping die that is easy to take to solve the above problem. Utility Model Content

[0026] Furthermore, the push assembly 3 includes a first movable groove 301, a push column 302, a limit ring 303, a first spring 304, a stopper 305 and a slider 306. Two groups of first movable grooves 301 are provided in the support frame 1. The push column 302 is movably connected in the first movable groove 301. The upper surface of the push column 302 is an inclined surface. The bottom of the push column 302 is fixedly connected to the limit ring 303. The lower side of the limit ring 303 is provided with a first spring 304. The outer side of the push column 302 is provided with a stopper 305. The front and rear sides of the stopper 305 are fixedly connected with two groups of sliders 306. The limit assembly 4 is provided in the push column 302. Figure 3 As shown, the structure is used to push the push column 302 downward through the upper mold 203, causing the first spring 304 to deform, and the push column 302 is positioned on the lower side of the stop block 305 through the limit assembly 4. When the upper mold 203 rises, the push column 302 is restored to its original position under the rebound action of the first spring 304.

[0027] Furthermore, the transmission assembly 5 includes a fixed block 501, a fixed rod 502, a connecting rod 503 and a push rod 504. Two sets of fixed blocks 501 are fixedly connected to the outside of the support frame 1, the fixed block 501 is fixedly connected to the inside of the fixed rod 502, the surface of the fixed rod 502 is movably connected to the connecting rod 503, the inner side moving head of the connecting rod 503 is rotatably connected to the outer side of the stopper 305, the outer end of the connecting rod 503 is rotatably connected to the push rod 504, and the upper end of the push rod 504 is fixedly connected to the support platform 202. Figure 5 As shown, the structure is used to drive the push rod 504 to move downward through the support platform 202, thereby driving the outer end of the connecting rod 503, and rotating the connecting rod 503 through the fixed rod 502, driving the stopper 305 at the right end to move upward through the slider 306, and vice versa.

[0028] Furthermore, the limiting assembly 4 includes a second movable groove 401, a movable block 402, a limiting block 403 and a second spring 404. The push column 302 is provided with a second movable groove 401, the movable block 402 is movably connected in the second movable groove 401, the outer side of the movable block 402 is fixedly connected to the limiting block 403, and the second movable groove 401 is provided with a second spring 404. The two ends of the second spring 404 are respectively against the inner walls of the second movable groove 401 and the movable block 402. Figure 4 As shown, this structure is used to push the column 302 to move downward and when it reaches the specified position, the second spring 404 pushes the movable block 402 to clamp the limit block 403 at the lower end of the stop block 305 to position the column 302.

[0029] Furthermore, four groups of positioning columns 7 are fixedly connected to the four corners of the surface of the support frame 1, and four groups of sliding sleeves 6 are fixedly connected to the four corners of the support platform 202. The sliding sleeves 6 are provided with movable grooves adapted to the positioning columns 7. Figure 2 As shown, the structure is used to make the device move stably through the coordinated use of four groups of positioning columns 7 and the sliding sleeve 6, avoiding deviation and enhancing the stability of the device.

[0030] Furthermore, three groups of third springs 8 are arranged between the two groups of upper molds 203, and dampers are arranged inside the third springs 8. Figure 2 As shown, the structure is used to effectively avoid serious surface wear and inconvenience of use of the upper mold 203 after long-term use through three sets of third springs 8, thereby ensuring the stamping effect of the upper mold 203 on the material and improving the working quality of the device.

[0031] Furthermore, the limiting block 403 is triangular, and the diameter of the second movable groove 401 is adapted to the movable block 402. Figure 4As shown, the structure is used to facilitate the positioning block 403 to be clamped on the lower side of the stopper 305 by making the stopper 403 triangular, and to facilitate the stopper 305 to push the stopper 403 to move into the second movable groove 401 when the stopper 305 moves downward.

[0032] Working principle: Before stamping operation, Figure 2 As shown, the material to be stamped is first placed on the surface of the lower die 204 and fits with the push column 302, and then the hydraulic cylinder 201 is controlled to operate, so that the support platform 202 drives the upper die 203 to descend along the positioning column 7 through the sliding sleeve 6 and fit with the upper end of the lower die 204. At this time, the upper die 203 presses the inside of the lower die 204 and completes the stamping of the material; Figure 5 As shown, the push rod 504 is driven downward by the support platform 202, thereby driving the outer end of the connecting rod 503, and the connecting rod 503 is rotated by the fixing rod 502, driving the stopper 305 at the right end to move upward through the slider 306. At the same time, Figure 3 and Figure 4 As shown, the upper mold 203 pushes the push column 302 to move downward, causing the first spring 304 to deform. When reaching the specified position, the movable block 402 is pushed under the action of the second spring 404 to clamp the limit block 403 at the lower end of the stop block 305, and the push column 302 is positioned at the lower side of the stop block 305.

[0033] After stamping is completed, Figure 2 As shown, the hydraulic cylinder 201 controls the support platform 202 to move the upper mold 203 upward. Figure 3 and Figure 5 As shown, at this time, the push rod 504 drives the connecting rod 503 to rotate, so that the stop block 305 moves downward. When the stop block 305 moves downward, it pushes the limit block 403. The limit block 403 moves into the second movable groove 401 and is stored in the second movable groove 401. Under the rebound action of the first spring 304, the push column 302 is pushed to move upward, pushing the product outward, and the product is made to slide into the storage bucket through the inclined surface of the push column 302. The above is the entire working principle of the utility model.
