Detailed Implementation

[0016] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0018] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1 , 2As shown in Figures 4 and 5, a terminal stamping die includes a lower die base plate 1, a lower die pad plate 2 disposed on the lower die base plate 1, a lower template plate 3 disposed on the lower die pad plate 2, a plurality of lower die cores 4 disposed within the lower template plate 3, an upper die base plate 5, an upper pad plate 6 disposed on the upper die base plate 5, an upper clamping plate 7 disposed on the upper pad plate 6, an upper template plate 8 disposed on the upper clamping plate 7, and a plurality of upper die cores 81 disposed within the upper template plate 8. The lower die pad plate 2 is provided with a locking mechanism 9 for locking two adjacent lower die cores 4. The locking mechanism 9 includes a locking wedge block 91 detachably connected to the lower die pad plate 2 and two locking bars 92 respectively disposed on two adjacent lower die cores 4. The two locking bars 92 are respectively provided with a beveled surface 921 on opposite sides. A locking space 900 is formed between the beveled surfaces 921 of the two locking bars 92. The locking wedge block 91 is fitted into the locking space 900. The locking wedge 91 is connected to the lower mold pad 2 via an adjusting bolt 93. The locking wedge 91 rotates with the adjusting bolt 93 and slides back and forth along the chamfered surfaces 921 of the two locking bars 92. The locking wedge is connected to the lower mold pad via the adjusting bolt. By rotating the adjusting bolt, the locking wedge is driven to slide between the two locking bars, thereby adjusting the tightness of the two lower mold cores. Each locking bar 92 is provided with a limiting plane 922 that transitions with the chamfered surface 921. The width between the two chamfered surfaces 921 gradually decreases from the lower mold plate 3 towards the lower mold pad 2. The limiting plane on the locking bar that cooperates with the locking wedge ensures that the locking wedge is reliably engaged between the two locking bars, thus improving the working reliability of the locking mechanism.

[0020] like Figure 2 and 4As shown, each lower die core 4 is provided with a punching hole 41. A scrap ejection mechanism 10 is slidably disposed in the lower die base plate 1 to eject the scrap from the punching hole 41. The scrap ejection mechanism 10 includes a backing plate 11 slidably disposed in the lower die base plate 1, a scrap top plate 12 linked to the backing plate 11, and multiple ejector pins 13. The multiple ejector pins 13 are linked to the scrap top plate 12. When the stamping die performs the mold opening action, the scrap top plate 12 drives the multiple ejector pins 13 to pass through the lower die pad 2 and the lower die plate 3 in sequence and extend into the punching hole 41. During mold opening, the scrap ejection mechanism can eject the scrap from the punching hole of the lower die core, thereby achieving the function of cleaning scrap. A snap-fit ​​plate 14 is provided on the backing plate 11, and a snap-fit ​​groove 141 is provided on the snap-fit ​​plate 14 to engage with the ejector pin 15. The snap-fit ​​plate on the backing plate to engage with the ejector pin facilitates the installation of the stamping die. During mold opening, the drive mechanism drives the guide plate via the ejector rod, which in turn drives the scrap ejector plate and ejector pin to eject the scrap from the punch hole of the lower mold core. The lower mold base plate 1 has multiple support pillars 111 arranged in a rectangular array, and the upper mold base plate 5 has multiple guide sleeves 51 that are slidably connected to the support pillars 111. The lower mold base plate is slidably connected to the upper mold base plate via the multiple support pillars and guide sleeves, ensuring that the upper mold base plate can reliably perform mold opening and closing actions on the multiple support pillars, thus improving the operational reliability of the stamping die.

[0021] like Figure 1 and 2 As shown, the lower die pad 2 is provided with a die-fitting chamfer 21, and the lower die plate 3, upper die pad 6, upper clamping plate 7, and upper die plate 8 are provided with multiple chamfers 22 arranged in the same manner as the die-fitting chamfer 21. The die-fitting chamfers and chamfers can serve as die-fitting indicators, which can prevent the die from being installed backwards, thereby improving the die-fitting efficiency of the stamping die.

[0022] A locking mechanism is added between the two lower mold cores. This locking mechanism adopts a wedge-type structure design, with the locking wedge block fitting between the two locking strips on the two lower mold cores. This allows for quick assembly and disassembly of the lower mold cores, which helps improve production efficiency. Furthermore, the locking force of the locking wedge block can be adjusted by rotating the adjusting bolt, thereby adjusting the tightness of the locking wedge block on the lower mold core, making operation more convenient.

[0023] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
