DETAILED DESCRIPTION

[0024] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0025] like Figures 1 to 4 As shown, this embodiment proposes a punching structure for an engineering mold, which includes an upper mold base 11 and a lower mold base 12. An upper die assembly 13 is installed at the lower end of the upper mold base 11, and a lower die assembly 14 is installed at the upper end of the lower mold base 12. A punching structure is provided on the edge of the upper die assembly 13, and the punching structure includes: an oblique driving block 15, which is installed on the upper mold base 11 through a reset member 25; a punch 16, which is installed at the lower end of the oblique driving block 15; a guide assembly, which is arranged at the edge of the lower die assembly 14, and the guide assembly limits the movement direction of the oblique driving block 15; and an oblique hole 17 is provided on the lower die assembly 14, which is used to accommodate the punch 16.

[0026] The product to be processed is placed between the upper die assembly 13 and the lower die assembly 14. When the upper die holder 11 drives the upper die assembly 13 downward, the product's appearance is processed. Simultaneously, the inclined drive block 15 moves under the action of the guide assembly, and the punch 16 follows the inclined drive block 15 to punch the product.

[0027] This solution can punch oblique holes in the product while processing the product appearance, effectively simplifying the product processing steps, saving mold costs and effectively improving product processing efficiency.

[0028] Furthermore, a vertical arm 18 is provided at the lower edge of the upper die base 11, and the oblique drive block 15 is mounted on the vertical arm 18 via a reset member 25. The reset member 25 can be a reset spring or a nitrogen gas spring, and the reset member 25 is configured to extend and retract horizontally. Furthermore, the oblique drive block 15 is slidably mounted on a slide rail of the upper die base 11.

[0029] When the upper die holder 11 drives the upper die assembly 13 and the oblique drive block 15 downward, the guide assembly causes the oblique drive block 15 to move in an oblique direction. This compresses the reset member 25, and simultaneously, the punch 16 punches the product. The guide assembly comprises a first oblique block 21 and a second oblique block 22. The first oblique block 21 is fixed to the edge of the lower die assembly 14; the second oblique block 22 is fixed to the vertical portion 20, with the second oblique block 22 and the first oblique block 21 in surface contact. The punch 16 is arranged in an oblique direction, parallel to the oblique direction of the first oblique block 21.

[0030] As an implementation of this embodiment, the oblique driving block 15 has a horizontal portion 19 , and the end of the horizontal portion 19 facing the reset member 25 has a vertical portion 20 extending downward, and the punch 16 is installed at the end of the horizontal portion 19 away from the reset member 25 .

[0031] Furthermore, a pressure block 23 is provided at the end of the upper die assembly 13. The pressure block 23 has a guide hole for slidingly mounting the punch 16. This guides the movement of the punch 16 and improves its smoothness. Furthermore, a chip removal opening 24 is provided on the lower die base 12. This opening 24 is connected to the inclined hole 17 and is used to remove waste material after punching.

[0032] This solution works as follows:

[0033] The product is placed on the lower die assembly 14 of the lower die base 12. At this time, the product is located between the upper die assembly 13 and the lower die assembly 14. When the external drive mechanism drives the upper die base 11 downward, the upper die assembly 13 and the lower die assembly 14 jointly extrude to shape the product. At the same time, the oblique drive block 15 also moves downward with the upper die base 11. Under the action of the first oblique block 21 and the second oblique block 22, the oblique drive block 15 moves downward at an angle. At this time, the punch 16 punches the product, and the waste material flows out through the oblique hole 17 and the chip discharge port 24. At the same time, the reset member 25 is in a compressed state.

[0034] When the external driving mechanism drives the upper die base 11 to move upward, the reset member 25 gradually returns to its initial state. Under the action of the first inclined block 21 and the second inclined block 22, the inclined driving block 15 moves up in the inclined direction. At this time, the punch 16 withdraws from the inclined hole 17.

[0035] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
