Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to a mold for manufacturing a 5G shield with special reinforcing ribs. Background Technology

[0002] Shielding devices are present in terminal products such as communication devices that require shielding functions. These devices are mounted on the PCB board of the electronic module and are designed to provide shielding.

[0003] Applications of the shielding cover: It can be used in conjunction with PCB circuit boards, set-top boxes, mobile phones, telecommunications equipment, etc.

[0004] The function of a shielding cover is primarily to block electromagnetic waves from entering, protecting them from harmful electromagnetic radiation. Shielding covers are tools used to shield electronic signals. Their purpose is to shield external electromagnetic waves from affecting internal circuitry and to prevent internally generated electromagnetic waves from radiating outwards.

[0005] With the advent of 5G, there is a greater demand for higher-frequency data transmission. Therefore, numerous notched shielding covers are used to facilitate data transmission on PCBs. Traditionally, data transmission on PCBs involves creating notches in the shielding cover to allow the copper busbars on the PCB to pass through. The shielding cover provides the shielding effect, while the copper busbars on the PCB serve the data transmission function.

[0006] In the continuous stamping die industry for shielding covers, because the specifications of the shielding cover materials exceed 40x40mm, the surface of the shielding cover may collapse due to the thermal expansion and contraction of high-temperature gases during welding and assembly. This results in uneven surfaces during assembly, which can easily lead to contact between electronic components. Therefore, many larger shielding covers use welded support blocks to solve this problem. Due to space utilization constraints, many shielding covers now use reinforcing ribs on large flat surfaces to overcome this issue. However, because the shape of the reinforcing ribs is close to a "well" shape, mold design and manufacturing are not very convenient. This can easily cause stress, leading to unevenness or poor appearance. Conventional mold designs generally use slotted upper and lower parts and a forced stamping method without material pressure, resulting in poor appearance and flatness. The method of adding reinforcing ribs involves forcibly deforming the material through convex and concave ribs to form the ribs. However, without material pressure during operation, the material is easily deformed when the ribs are formed, resulting in uneven flatness of the shielding cover product.

[0007] In the stamping process of the aforementioned mold industry, the requirement for extremely high stress release in the stamped (embossed) metal material is very challenging. It is difficult to meet the part requirements when designing and manufacturing stamping dies, making it a persistent problem in the stamping industry. To achieve better and more stable embossed effects, better manufacturing solutions must be developed. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a mold for manufacturing a 5G shielding cover with special reinforcing ribs. This mold utilizes high-pressure pressing to draw the material, overcoming material stress and ensuring uniform stress distribution on the drawn reinforcing ribs, thus reducing stress. This improves production efficiency, enhances the quality of cold-stamped products, reduces risks, improves mold stability, and increases productivity.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0010] By utilizing the pre-compression effect of the mold spring force, instead of the hard forming method used in existing technologies, a strong pressing method is adopted to stretch the material, overcome the material stress, and make the stretching reinforcing ribs uniformly stressed and reduce stress.

[0011] When designing the mold, a strong pressing structure is intentionally added to the reverse side of the ribs of the material being cold-stamped. During mold operation, the material is first pressed with strong force to keep it fixed and stable, unaffected by external forces, and then squeezed into the reinforcing ribs to reduce material stress and prevent deformation of the metal material when it works in the mold.

[0012] This utility model provides a mold for manufacturing a 5G shield with special reinforcing ribs, including: an upper mold and a lower mold; a shield with reinforcing ribs is formed between the upper mold and the lower mold;

[0013] The lower mold includes a powerful buoyancy block and a reinforcing rib part fixing block. A powerful spring force transmission pin is provided between the powerful buoyancy block and the reinforcing rib part fixing block. The powerful buoyancy block is controlled to float by twisting the powerful spring force transmission pin.

[0014] A reinforcing rib is provided between the high-strength buoyancy block and the reinforcing rib fixing block; a reinforcing rib groove is provided on the lower mold, and the shielding material is squeezed into the reinforcing rib groove of the upper mold to form a reinforcing rib.

[0015] Furthermore, the powerful buoyancy block has a powerful buoyancy height of 1.5 mm.

[0016] Furthermore, the powerful buoyancy block is equipped with a limiting pressure plate.

[0017] Furthermore, the limiting pressure plate is connected to the powerful buoyancy block by limiting pressure plate screws.

[0018] Furthermore, the reinforcing rib is fixed to the lower mold by a reinforcing rib fixing pin.

[0019] Furthermore, the reinforcing rib part has two fixing pins.

[0020] Furthermore, the reinforcing rib fixing pin is provided on the reinforcing rib fixing block.

[0021] Furthermore, the cross-section of the reinforcing rib is shaped like a "well".

[0022] Furthermore, when the powerful buoyant block is in the floating state, the reinforcing ribs are not exposed; when the lower mold is in the closed state, the reinforcing ribs are exposed.

[0023] Furthermore, the high-strength spring transmission pin is provided with four pins.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] The strong pressure exerted by the powerful floating blocks ensures a smooth material flow, reducing material stress and thus preserving flatness. The dimensions and appearance meet industry standards. The use of strong pressure to draw the material overcomes stress, resulting in uniform stress distribution on the reinforcing ribs and reduced overall stress. This directly impacts the manufacturing process of cold-stamped shielding covers, improving the stable manufacturing standards for large-format, thin-material 5G shielding covers with reinforcing ribs, enhancing competitiveness, significantly improving quality and cost, increasing production efficiency, improving the quality of cold-stamped products, reducing risks, enhancing mold stability, and increasing productivity.
