[0021] In the embodiment, the mounting frame 102 is fixed above the base 101, and the base 101 and the mounting frame 102 are fixed by positioning pins and bolts respectively.

[0022] Wherein, the lower mold body 103 is provided with T-shaped parts 109 on both sides, and a plurality of integral connecting screw rods on the back side pass through a plurality of through holes on the back side of the base 101, and are then tightly fixed by a plurality of first nuts 106. The moving seat 104 is arranged above the lower mold body 103. The upper mold body 105 is provided with T-shaped parts 109 on both sides, and a plurality of integral connecting screw rods on the back side pass through a plurality of through holes on the back side of the moving seat 104, and are then tightly fixed by a plurality of second nuts 107. The sleeve pipe 108 is arranged on the top of the mounting frame 102 and is close to the downward device. The downward device is arranged on the side of the mounting frame 102 close to the upper mold body 105. The base 101 and the moving seat 104 are respectively provided with non-penetrating installation grooves from front to back, and the inner walls on both sides of the installation grooves are provided with T-shaped sliding grooves, so as to facilitate the installation of the lower mold body 103 and the upper mold body 105. The back sides of the lower mold body 103 and the upper mold body 105 are respectively provided with four integral screw rods, and the outer diameter of the optical axis of the screw rod is greater than the outer diameter of the external thread end, so as to facilitate the passing through the through holes on the back side of the base 101 or the moving seat 104 without damaging the thread. The first nut 106 and the second nut 107 can be respectively installed on the integral screw rod on the back side of the lower mold body 103 and the upper mold body 105. The positioning column on the sleeve pipe 108 is tightly fixed on the mounting frame 102 by bolts, and welding fixation can also be used. The sleeve pipe 108 is used for air pipe passing through, so as to avoid the air pipe entering between the lower mold body 103 and the upper mold body 105 during stamping, causing breakage. The downward device is used to drive the vertical movement of the upper mold body 105. The lower mold body 103 and the upper mold body 105 are used for the structure of scissor leg placement and cooperation stamping, which can directly adopt the structure of the stamping upper die and the stamping lower die in the prior art CN106363695B, and other prior art structures can also be used, which is not limited here.

[0023] Secondly, the cylinder 110 is fixed on the top of the mounting frame 102, and the output end is connected with the moving seat 104. The guide assembly is arranged on both sides of the moving seat 104. The bottom end cover of the cylinder 110 is tightly fixed on the mounting frame 102 by bolts arranged from bottom to top, and the working pressure is adjusted by an oil-water separator or a pressure regulating valve on the gas delivery pipeline. The guide assembly is used for vertical movement guide of the upper mold body 105.

[0024] Then, the connecting plate 111 and the movable base 104 are integrally formed and symmetrically arranged; the mating component is arranged on the side of the base 101 near the connecting plate 111. The connecting plate 111 is provided with mounting holes to facilitate the installation of the mating component.

[0025] Finally, the guide rod 113 is threadedly connected to the base 101 and symmetrically arranged, penetrating the connecting plate 111; the T-shaped linear sliding bearing 112 is fixed on the connecting plate 111 and slidably connected to the guide rod 113. The T-shaped linear sliding bearing 112 is fixed to the connecting plate 111 by bolts, and the bottom external thread end of the guide rod 113 is connected to the threaded mounting hole on the base 101 for installation, while the upper optical shaft end slides with the T-shaped linear sliding bearing 112 for guidance.

[0026] When using this utility model to solve the problem of the cumbersome and inconvenient process of replacing the upper and lower dies of existing scissor-foot stamping dies, which requires disassembling multiple bolts and positioning pins, the following steps are taken: First, when installing the lower die body 103, its two T-shaped portions 109 are engaged with the T-shaped grooves on the base 101 and pushed in from front to back. After multiple integrated connecting screws pass through multiple through holes on the rear side of the base 101, they are tightened and fixed by multiple first nuts 106 to achieve installation. When installing the upper die body 105, its two T-shaped portions 109 are engaged with the T-shaped grooves on the movable seat 104 and pushed in from front to back. After multiple integrated connecting screws pass through multiple through holes on the rear side of the movable seat 104, they are tightened by multiple second nuts 107. The scissor-shaped die is fixedly installed. During stamping, the scissor-shaped die is placed on the lower die body 103. Then, the cylinder 110 is controlled to push the upper die body 105 downward to cooperate with the lower die body 103, thereby realizing scissor-shaped die stamping and cutting. When replacing the lower die body 103 and the upper die body 105, it is only necessary to completely remove the four first nuts 106 and the second nuts 107 respectively, and then pull them forward to disassemble. Moreover, due to the setting of the T-shaped part 109, it is not necessary to set a positioning pin structure. Compared with the existing method of disassembling bolts and positioning pins at the same time, it is more convenient to replace the die. This solves the problem that the existing scissor-shaped die stamping die requires the disassembly of multiple bolts and positioning pins when replacing the upper and lower dies, which is cumbersome and inconvenient to use.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3It is the overall structure schematic diagram of notebook computer scissors foot punch press mould, on the basis of first embodiment, the utility model provides a kind of notebook computer scissors foot punch press mould, the notebook computer scissors foot punch press mould further includes protection mechanism, the protection mechanism includes shield 201 and top plate 202.

[0029] Wherein, the shield 201 is fixed on the mounting bracket 102 and located outside the air cylinder 110;The top plate 202 is fixed on the top of the shield 201. The both sides of the shield 201 install ear and be fixed by bolt, the top plate 202 is fixed by bolt, because the rear side of the air cylinder 110 needs to be provided with air pipe, so the rear side of the shield 201 is not closed, to facilitate air pipe setting.

[0030] In the embodiment, the front side and the left and right sides of the air cylinder 110 are protected from impact by the shield 201, improving safety, and the top plate 202 is used to protect the top of the air cylinder 110.
