Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 A flanging die structure for a tapered slider includes an upper die base 1 and a lower die base 9. The upper die base 1 has a wedge-shaped slider 2 and an upper clamping plate 3 below it. A nitrogen spring 4 connects the upper die base 1 and the wedge-shaped slider 2. One end of the upper clamping plate 3 is connected to one end of a nitrogen spring 5, and the other end of the nitrogen spring 5 is connected to a stripper plate 6. A flanging die 7 is provided on one side of the stripper plate 6, and an inner ejector block 8 is provided on one side of the flanging die 7. A wedge-driven block 12 is provided at the upper end of the lower die base 9. One side of the wedge-shaped slider 2 is an inclined surface. One side of block 12 is an inclined surface. The inclined surface of the inclined wedge slider 2 and the inclined wedge drive block 12 are matched. The lower mold base 9 is embedded with a slider base 13 and a fixed base 14. One side of the fixed base 14 is an inclined surface and a lower pad 16 is provided in contact with the inclined surface. A lower clamping plate 15 is provided on one side of the lower pad 16. A flanging punch 18 is provided on one side of the lower clamping plate 15. The upper end of the slider base 13 is provided with an installation groove. A slider 20 is provided in the installation groove. The upper end of the slider 20 abuts against the lower end of the flanging punch 18. Pressure plates 21 are provided on both sides of the installation groove on the slider base 13.

[0019] An upper pressure plate 27 is provided on one side of the upper mold base 1.

[0020] The lower end of the upper mold base 1 is fixed with several guide pillars 23, and the upper end of the lower mold base 9 is provided with several guide sleeves 24 that are structurally matched with the guide pillars 23. The cooperation between the guide pillars and the guide sleeves ensures the accurate alignment and stable operation of the upper mold base and the lower mold base during the mold opening and closing process, and avoids processing errors and mold damage caused by position offset.

[0021] The upper mold base 1 is provided with an upper limit post 25 at its lower end, and the lower mold base 9 is provided with a lower limit post 26 at its upper end, which corresponds to the upper limit post 25, to ensure the tightness and stability of the mold when it is closed.

[0022] The lower end of the lower mold base 9 is connected to several lower pads 11, and the lower end of the lower pads 11 is connected to the lower support plate 10, which provides a certain shock absorption and support function, and improves the stability of the mold during operation.

[0023] Storage blocks 17 are provided on both sides of the flange mold.

[0024] In operation, the upper mold base 1 moves downward, and the inclined wedge slider 2 begins to contact the inclined wedge drive block 12. The inclined surfaces cooperate and slide along the inclined surfaces, pushing the slider 20 to move along the lower mold angle. The stripper plate 6 presses down on the product 22, and the slider 20 continues to move until the flanging punch 18 contacts the product 22, completing the flanging of the product 22. The upper mold base 1 continues to descend until the mold is closed. Then, the upper mold base 1 moves upward, and the inclined wedge slider 2 and slider 20 move backward along the mold angle, allowing the stripper plate 6 to strip the material. The flanging die 7 also ejects the product 22 at a certain angle, and the inclined wedge slider 2 subsequently ejects the product 22, completing the ejection of the product 22. This process continues until the upper mold base 1 finishes moving upward, completing one cycle and awaiting the next.
