[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This utility model relates to a punching die for cutting edges on automotive button covers, such as... Figure 1 , Figure 2 As shown, the mold includes a mold body 1, which includes a fixing component 2, a punching component 3, and a receiving component 4. The fixing component 2 is used to connect each component so that each component can perform its corresponding function. The punching component 3 is used to punch the sheet metal to form multiple car button covers. The receiving component 4 is used to receive the blown-out car button covers. The fixing component 2 includes an upper worktable 5 and a lower worktable 6. Multiple connecting columns are fixed between the upper worktable 5 and the lower worktable 6. The upper worktable 5 is provided with a through hole. The punching component 3 passes through the through hole and is slidably connected to the through hole. One end of the receiving component 4 is fixedly connected to the upper worktable 5. At least a part of the receiving component 4 is hinged to the punching component 3.

[0020] like Figures 2-5 As shown, the punching assembly 3 includes a lifting column 7 and a punching head 8. The punching head 8 is fixedly installed at the bottom end of the lifting column 7. The punching head 8 is made of high-strength alloy steel, which can more effectively punch the sheet metal into a car button cover. There are multiple punching heads 8, each punching head 8 has an air hole 9 inside, and a cutting blade 10 is provided on the outside of the punching head 8. The cutting blade 10 is integrally formed with the punching head 8. The other end of the lifting column 7 is provided with a suction air pump 11. The suction air pump 11 has an air extraction hole and an air injection hole. The air extraction hole and the air injection hole are connected to each air hole 9 through an air pipe 17. When the sheet metal is punched to form a car button, When the cover plate is being covered, the air pump 11 pumps air to ensure that the sheet metal fits tightly against the punching head 8. The lower worktable 6 is equipped with multiple punches 18, each punch 18 corresponding to a punching head 8. The lifting column 7 presses down so that each punching head 8 cooperates with the punch 18 to press the sheet metal into shape. The cutter 10 on the punching head 8 separates it from the excess material, while the shaped material remains inside the punching head 8. The lifting column 7 rises, and after the receiving assembly 4 moves to below all the punching heads 8, the air pump 11 pumps air to blow each shaped material onto the receiving assembly 4. The shaped material then slides along the receiving assembly 4 into the storage container provided by the worker.

[0021] like Figure 2 , Figure 3As shown, the receiving assembly 4 includes a receiving shovel 12, a first connecting rod 13, a round rod 14, and a second connecting rod 15. The receiving shovel 12 has an opening at one end away from the punching assembly 3. A fixing plate 16 is fixedly connected to the upper worktable 5. Two first connecting rods 13 are provided, with one end of each first connecting rod 13 hinged to the fixing plate 16. One end of the receiving shovel 12 has a through hole, through which the round rod 14 passes and is fixedly connected to the other ends of the two first connecting rods 13 on the receiving shovel 12. The punching assembly 3 has two protrusions, and the second connecting rod 15... One end of the connecting rod 15 is hinged to two protrusions, and the round rod 14 passes through the other end of the second connecting rod 15. The second connecting rod 15 is rotatably connected to the round rod 14. When the lifting column 7 descends, the horizontal angle of the second connecting rod 15 decreases, pushing the receiving shovel 12 outward from the lifting column 7. When the lifting column 7 rises, the horizontal angle of the second connecting rod 15 increases, pulling the receiving shovel 12 down towards the lifting column 7 until the receiving shovel 12 is completely below each punching head 8. After the formed material falls, it falls into the receiving part from the opening of the receiving shovel 12.

[0022] Working principle: First, the lifting column 7 rises, and the worker places the sheet metal to be punched onto the punch 18 on the lower worktable 6. Then, the lifting column 7 descends, and the air pump 11 draws air to hold the sheet metal while punching it. Subsequently, the lifting column 7 rises again, and each punched car button cover remains inside the punching head 8. At this time, the receiving shovel 12 is pulled to the bottom of each punching head 8, and the air pump 11 blows air to blow each formed car button cover onto the receiving shovel 12. The cover then falls from the opening of the receiving shovel 12 into the worker's own storage container.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
