Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Please see Figures 1 to 4 The utility model is a charger connector punching die, which comprises an upper die 1 and a lower die 2 connected with the upper die 1.

[0027] Please see Figure 1 to Figure 2 The upper die 1 includes an upper die base 11, an upper die plate 12 installed on the upper die base 11, a punch 13 arranged in the upper die plate 12, and an insert punch 14 located outside the punch 13. The upper die base 11 is in a horizontal state, and the upper die plate 12 is fixed to the lower surface of the upper die base 11 for fixing the punch 13 and the insert punch 14.

[0028] The shape of the punch 13 changes according to demand. Its top end is fixedly connected to the upper template 12, and the bottom end extends vertically downward. The punch 13 moves synchronously with the upper template 12. When the upper mold 1 moves to dock with the lower mold 2, the bottom end of the punch 13 extends into the product and cooperates with the lower mold 2 to fix the product.

[0029] One end of the insert punch 14 is fixed in the upper template 12, and the other end thereof extends vertically downward. The length of the insert punch 14 is greater than the length of the punch 13. In this embodiment, there are four insert punches 14 and they surround the punch 13. The opposite sides of several insert punches 14 have a first protrusion 15. The first protrusion 15 is formed by protruding inward from the inner surface of the insert punch 14, and the positions of the first protrusions 15 of the multiple insert punches 14 are different.

[0030] The upper mold 1 is also provided with a blowing part 16, which includes a blowing port 161 and a blowing channel 162 connected to the blowing port 161. The blowing port 161 is provided on the upper mold plate 12 for connecting a blowing device (not shown). The blowing channel 162 runs through the upper and lower ends of the punch 13.

[0031] Please see Figure 1 and Figure 3 The lower mold 2 includes a lower mold base 21, a lower mold plate 22 installed on the lower mold base 21, a swing block 23 arranged in the lower mold plate 22, and a limit member 24 for limiting the movement of the swing block 23. The lower mold base 21 is in a horizontal state, and the lower mold plate 22 is fixed to the upper surface of the lower mold base 21 for fixing the swing block 23 and the limit member 24.

[0032] The lower template 22 is recessed inward from the surface to form a receiving groove 25 . The diameter of the receiving groove 25 is larger than the spacing between the oppositely arranged punches 14 and the diameter of the swing block 23 . The swing block 23 is placed in the receiving groove 25 .

[0033] Please see Figure 3 to Figure 4 The pendulum block 23 is recessed inward from the upper surface to form a working groove 231. The shape of the working groove 231 changes according to the shape of the product and is used to place the product, that is, the bottom of the product extends into the working groove 231. The pendulum block 23 also has a second protrusion 232 protruding outward from the side surface. The number of the second protrusions 232 changes according to demand. Multiple second protrusions 232 surround the pendulum block 23 and correspond to the first protrusions 15. When the insertion punch 14 extends to the outside of the pendulum block 23, the first protrusion 15 squeezes the pendulum block 23 or the second protrusion 232 squeezes the insertion punch 14, the pendulum block 23 deviates, the distance between the working groove 231 and the punch 13 is reduced, and a certain area of ​​the product is cut off. Subsequently, another first protrusion 15 squeezes the pendulum block 23 or the second protrusion 232 squeezes the insertion punch 14 to cut off another area of ​​the product. According to the above movement process, the pendulum block 23 is squeezed by the insertion punch 14 to make a circular motion, so that the working groove 231 and the punch 13 surround the cut product, so that the product is separated from the cut part.

[0034] The limiting member 24 is installed in the receiving groove 25 and is located above the swing block 23 . The limiting member 24 is fixedly connected to the lower template 22 to limit the swing block 23 from floating up and down.

[0035] The lower mold 2 also includes a reset rod 26, the bottom of which is fixedly connected to the lower mold plate 22, and the top of which extends vertically upward into the receiving groove 25. The top of the reset rod 26 forms an arc-shaped surface, and the bottom of the pendulum block 23 is recessed inward from the surface to form a docking groove 233. The docking groove 233 is an arc-shaped groove and is connected to the top of the reset rod 26. When the pendulum block 23 is offset, the reset rod 26 does not completely withdraw from the docking groove 233. After cutting off the product, the pendulum block 23 is reset along the top of the reset rod 26 through the docking groove 233.

[0036] When a charger connector punching die of the utility model is used, the material belt drives the product into the working groove 231. When the upper die 1 moves to dock with the lower die 2, the bottom end of the punch 13 extends into the interior of the product and cooperates with the working groove 231 to fix the product. The punch 13 and the working groove 231 contact the inner and outer surfaces of the product respectively. The insertion punch 14 enters the receiving groove 25, and the insertion punch 14 extends to the outside of the swing block 23. The first protrusion 15 squeezes the swing block 23 or the second protrusion 232 squeezes the insertion punch 14, and the swing block 23 deviates. The distance between the working groove 231 and the punch 13 is reduced, and a certain area of ​​the product is cut off. Subsequently, another first protrusion 15 squeezes the swing block 23 or the second protrusion 232 squeezes the insertion punch 14, and another area of ​​the product is cut off. According to the above movement process, the swing block 23 is squeezed by the insertion punch 14 to make a circular motion, so that the working groove 231 and the punch 13 surround the cut product, so that the product is separated from the cut part. After the product is cut off, the swing block 23 is reset along the top of the reset rod 26 through the docking groove 233.

[0037] The utility model is a charger connector punching die, which has the characteristic of smooth incision. The bottom end of the punch is inserted into the interior of the product, and the product is fixed in cooperation with the working groove. The punch is inserted and squeezed with the pendulum block to cut off the product from the side of the product, thereby avoiding product deformation, uneven cutting and incomplete cutting of the arc surface, etc. Secondly, it is connected with the top of the reset rod through the docking groove, so that the pendulum block is always in the same position, reducing the problem of inaccurate cutting caused by incomplete reset of the pendulum block position.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
