In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor in the protection scope required by the present application.

[0033] Please refer to Figure 1 The Faraday cage assembly plate of the present application comprises a metal plate body 1, U-shaped grooves 101 are formed downward on both sides of the metal plate body 1, connecting ears 102 are formed at the edges of the U-shaped grooves 101 and the metal plate body 1, a plurality of through holes 103 are arranged in a rectangular array between the two U-shaped grooves 101 on the metal plate body 1, a hole plate 104 is formed on one side of the through hole 103, the hole plate 104 and the through hole 103 form an included angle a, in this embodiment, the thickness of the metal plate body 1 is 8mm, the through hole 103 is a square hole.

[0034] After the Faraday cage assembly plate is assembled into a Faraday cage, it is generally The mesh of the traditional Faraday cage is generally only 0.6mm thick; according to the shielding coefficient of the space grid shielding, the performance of lightning protection and electromagnetic interference resistance is stronger;

[0035] Among them, due to the setting of the hole plate 104, when installing other thermal insulation materials, the hole plate 104 can be inlaid into the thermal insulation plate, so that it is fixed more tightly, which is convenient for installing other materials on the Faraday cage assembly plate, and at the same time avoids waste when the through hole 103 is opened;

[0036] The setting of the U-shaped groove 101 can uniformly disperse the bearing capacity of the building, and improve the compression resistance and impact resistance of the wall;

[0037] The setting of the connecting ear 102 can facilitate the assembly and installation of adjacent Faraday cage plates.

[0038] Please refer to Figure 2 - Figure 6 A molding machine for producing the above-mentioned Faraday cage assembly plate, comprising a fixed mold 21 and a movable mold 22, a plurality of punching rods 23 are arranged in the fixed mold 21, and a punching part 231 is formed at the top of the punching rod 23; the punching rod 23 and the movable mold 22 are driven by hydraulic structure;

[0039] The movable mold 22 has several shaping holes 24 corresponding to the stamping rod 23.

[0040] The top view of the stamping part 231 is adapted to the top view of the through hole 103 on the metal plate 1. The number of edges of the through hole 103 is set to n. The stamping part 231 has n side surfaces equal to the number of edges of the through hole 103 n. The n side surfaces are provided with a stamping surface 2311 with a number of n-1 edges of the through hole 103 and a slope 2312. The included angle b formed by the slope 2312 is adapted to the included angle a of the hole plate 104. In this embodiment, n=4 according to the shape of the through hole 103.

[0041] The length of the slope 2312 is greater than the length of the orifice plate 104, which makes it easier for the orifice plate 104 to form an angle α with the plane of the through hole 103, effectively ensuring the shape and angle of the orifice plate 104.

[0042] The shaping hole 24 is provided with a shaping block 25 inside. The shaping block 25 is provided with a mating groove 251 for accommodating the stamping part 231. The mating groove 251 is provided with a shaping inclined inner wall 252 corresponding to the slope 2312 of the stamping part 231. The adjacent side distance c of the shaping inclined inner wall 252 of the mating groove 251 is greater than the adjacent side distance d of the slope 2312 of the stamping part 231.

[0043] The above technical solution effectively ensures that the width of the perforated plate 104, which is equal to the adjacent side distance d of the slope surface 2312 of the stamping part 231, is always smaller than the adjacent side distance c of the inner wall of the shaping inclined surface 252. That is, the two sides of the perforated plate 104 will not be attached to the inner wall of the docking groove 251, which effectively facilitates the subsequent detachment of the perforated plate 104 from the docking groove 251.

[0044] Furthermore, the bottom edges of the mating groove 251 and the shaping block 25 are chamfered to ensure the connection strength between the punched perforated plate 104 and the metal plate 1.

[0045] The fixed mold 21 is also provided with a demolding component 26 for demolding the metal plate 1. The demolding component 26 includes an elastic component 261 installed inside the fixed mold 21. The elastic component 261 is a spring. The bottom of the elastic component 261 is provided with a feeding rod 262. The feeding rod 262 protrudes partially from the bottom of the fixed mold 21 under the elastic force of the elastic component 261.

[0046] The forming machine 2 drives the movable die 22 to descend when stamping the metal plate body 1, and the blanking rod 262 in the stripper 26 retracts into the inside of the movable die 22, then the stamping rod 23 in the fixed die 21 moves upward under the drive of the hydraulic mechanism, and stamps the metal plate body 1 on the fixed die 21, because the stamping part 231 on the stamping rod 23 is arranged, that is, the stamping part 231 is located in the butt joint groove 251 of the shaping block 25, so that the metal plate body 1 has a through hole 103, and because the slope surface 2312 of the stamping part 231 and the corresponding shaping inclined inner wall 252 in the butt joint groove 251, the waste formed by the stamping through hole 103 is left on the edge of the through hole 103 to form a hole plate 104, then the movable die 22 and the stamping rod 23 reset under the drive of the hydraulic mechanism, in the resetting process, the blanking rod 262 in the stripper 26 presses the metal plate body 1 under the rebound of the spring, so as to facilitate the hole plate 104 in the butt joint groove 251 to be separated, and the blanking rod 262 pressing on the metal plate body 1 continues to move upward to pass the hole plate 104 in the overall movement of the movable die 22, so as to facilitate the metal plate body 1 to move on the fixed die 21.

[0047] The above is only the embodiment of the present application, and is not used to limit the present application. The present application can be variously changed and modified for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made in the spirit and principle of the present application shall be included in the scope of the claims of the present application.
