[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1 to Figure 2 As shown, in this embodiment, a mold for synchronous punching and beveling processing includes an upper mold base 1, a lower mold base 2, a punch needle 3, a pressure plate 4 and a lower pad 5. The upper end of the punch needle 3 is connected to the lower end of the upper mold base 1, and an inclined surface 6 is arranged around the outer side of the lower end of the punch needle 3. The lower pad 5 is located at the upper end of the lower mold base 2, and the pressure plate 4 is pressed above the lower pad 5. The lower end of the punch needle 3 passes through the pressure plate 4.

[0019] The product to be processed is placed on the top of the lower pad 5, and the product is held stable by the pressing plate 4. The upper die base 1 moves closer to the lower die base 2. The punch needle 3 passes through the pressing plate 4 from top to bottom and punches at the position of the product to be punched, and punches to the top of the lower pad 5 of the lower die base 2. In the process of the punch needle 3 punching the product, a hole is opened first, and then due to the downward pressure of the inclined surface 6, an inclined angle surface is formed on the inner side of the hole, and the punching and bevel pressing are processed and formed at one time.

[0020] Specifically, the punching needle 3 includes an upper connecting section 7, a middle forming section 8 and a lower passing section 9. The upper connecting section 7, the middle forming section 8 and the lower passing section 9 are integrally formed. The inclined surface 6 is located between the middle forming section 8 and the lower passing section 9. First, the lower passing section 9 performs a perforation process on the product, and the middle forming section 8 continues to move downward. The inclined surface 6 is pressed on the inner upper side of the hole position to perform a bevel process on the hole position in one step.

[0021] An upper clamping plate 10 is connected to the bottom of the upper die base 1, and the pressure plate 4 is fixed at the bottom of the upper clamping plate 10. An upper pad 11 is arranged in the middle between the upper die base 1 and the upper clamping plate 10, and the upper end of the punch pin 3 is fixedly connected to the upper pad 11. A lower mold plate 12 is arranged above the lower die base 2, and the lower pad 5 is located at the inner bottom of the lower mold plate 12. An upper mold plate 13 is arranged below the upper die base 1, and the pressure plate 4 is located at the bottom of the middle of the upper mold plate 13. A die insert 14 is arranged above the lower pad 5, and the pressure plate 4 is pressed on the upper end of the die insert 14.

[0022] In terms of details, the upper clamping plate 10 connects the upper pad 11 and the upper mold plate 13, the pressing plate 4 is fixed in the upper mold plate 13, the lower mold plate 12 is fixed on the lower mold base 2, and the lower pad 5 in the middle of the lower mold plate 12 is padded with the die insert 14 to support the product, so as to receive the punch 3 inserted from top to bottom.
