As Figure 1 shown, for a wire harness product 100 with a large consumption, the structure of the product is complex and the dimensional accuracy requirements are high. The two sides of the product need to be trimmed. Since the middle part of the wire harness product 100 is suspended, it is difficult to ensure the quality during the trimming process with a traditional blanking die. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a two-way extraction stamping die with high punching accuracy.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

The two sliders are both slidably connected in the chute of the slider seat and are arranged opposite to each other. The outer sides of the two sliders respectively abut against the lower ends of the two inclined push punches. The inner ends of the sliders have a convex block extending inward, and the convex blocks on the two sliders are arranged opposite to each other. The upper ends of the two inclined push punches are fixed on the upper template. The slider spring is arranged between the two sliders. The upper end of the forming punch is fixed on the upper template, and the lower end of the forming punch is opposite to the convex block on the slider.

[0006] There are two forming punches, and the lower ends of the two forming punches respectively cooperate with the two sides of the convex block on the slider to form a cutting edge.

[0007] The utility model further includes an upper die base, an upper baffle plate, an upper stripper plate, a lower die base, a large guiding component, a small guiding component, and a stripping spring; the upper template is fixed on the upper die base. The upper baffle plate and the upper stripper plate are fixed together and are located below the upper template. The upper baffle plate and the upper stripper plate are connected to the upper template through the small guiding component. The stripping spring is arranged between the upper die base and the upper baffle plate. The lower template is located below the upper stripper plate, and the lower template is fixed on the lower die base; the lower parts of the inclined push punch and the forming punch can respectively pass through the upper baffle plate and the upper stripper plate with a clearance and extend towards the slider; the large guiding component is installed between the upper die base and the lower die base, and the small guiding component is installed between the upper template and the lower template.

[0008] The upper template includes an upper backing plate and an upper clamping plate; the upper backing plate and the upper clamping plate are fixed together.

[0009] After adopting the above solution, since the utility model includes an upper template, a lower template, a slider seat, two sliders, slider springs, two inclined push punches, and a forming punch, during punching, the two inclined push punches respectively drive the two sliders to move inwards, extend into the middle suspended section of the wire harness product from both ends, and the lower ends of the two downward-moving forming punches respectively cooperate with both sides of the convex blocks on the sliders to form a cutting edge, cutting off both sides of the wire harness product. The punching accuracy is high. After punching is completed, the two sliders are separated from the suspended section of the wire harness product under the action of the slider springs, so as to facilitate the picking of the wire harness product.

[0019] As Figure 2 、 Figure 3 shown, the present utility model is a two-way extraction type stamping die, including an upper die base 1, an upper template 2, an upper baffle 3, an upper stripper plate 4, a lower template 5, a lower die base 6, a slider seat 7, two sliders 8, slider springs 9, two inclined push punches 10, a forming punch 20, a large guide assembly 30, a small guide assembly 40, and a stripping spring 50.

[0020] The upper template 2 is fixed on the upper die base 1. The upper baffle plate 3 and the upper stripper plate 4 are fixed together and located below the upper template 2. The upper baffle plate 3 and the upper stripper plate 4 are connected to the upper template 2 through the small guiding assembly 40. The stripping spring 50 is arranged between the upper die base 1 and the upper baffle plate 3. The lower template 5 is located below the upper stripper plate 4, and the lower template 5 is fixed on the lower die base 6. The large guiding assembly 30 is installed between the upper die base 1 and the lower die base 6, and the small guiding assembly 40 is installed between the upper template 2 and the lower template 5.

[0021] The upper template 2 includes an upper backing plate 21 and an upper clamping plate 22; the upper backing plate 21 and the upper clamping plate 22 are fixed together.

[0022] The slider seat 7 is installed on the lower template 5. The middle of the slider seat 7 has a chute 71. Two sliders 8 are both slidably connected in the chute 71 of the slider seat 71 and are arranged opposite to each other. The outer sides of the two sliders 8 are respectively abutted against the lower ends of two inclined push punches 10. The inner end of the slider 8 has a convex block 81 extending inwards.
