Description

Technical Field

[0001] This application relates to the technical field of precision injection molding, and in particular to a deformation-resistant composite structural component for communication devices and a communication device. Background Technology

[0002] Injection molding is a technology that combines plastic and metal components into a single unit, primarily used in the automotive, electronics, and machinery industries. This process is characterized by high molding precision, high production efficiency, and stable quality. It is particularly crucial in the manufacturing of structural components for communication equipment. By precisely controlling mold temperature and injection pressure, a tight bond between the plastic and metal components is ensured, improving product durability and aesthetics.

[0003] like Figure 1 As shown, this structural component consists of two hardware parts, one of which is an ultra-thin hardware part with a thickness of 0.2mm (thickness less than 0.5mm). However, during the injection molding process, due to factors such as the impact of molten plastic, cooling shrinkage force, and mold closing pressure, the ultra-thin hardware part is prone to deformation, displacement, or poor bonding, which seriously affects the structural strength and assembly accuracy of the product. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a deformation-resistant composite structural component and communication device that avoids deformation of ultra-thin hardware parts.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A deformation-resistant composite structural component for communication equipment, comprising:

[0007] A first metal component includes a flat plate portion and two side plate portions. The two side plate portions are located on both sides of the flat plate portion and are perpendicular to the flat plate portion. The flat plate portion has a through hole and a fixing hole. The through hole is located in the middle of the flat plate portion and the fixing hole is located at both ends of the flat plate portion. The through hole is used to support the component during injection molding.

[0008] A plastic connecting assembly includes a first connector and a second connector. Both the first and second connectors have a fixing post on their side facing the flat plate portion. The fixing post passes through a corresponding fixing hole. The plastic connecting assembly is an injection-molded integral structure. The second connector is used to abut against the support assembly during injection molding.

[0009] The second metal component includes a straight section, a curved section, and a bent section. The two ends of the curved section extend along the axis from the straight section. The bent section is formed at the end of the straight section away from the curved section. The first connector is disposed in the middle of the curved section. The second connector is disposed in the curved section. The fixing post is located in the fixing hole.

[0010] The plastic connecting assembly is formed by injection molding; during injection molding, the support component of the injection mold abuts against the second connecting member through the through hole.

[0011] In one embodiment, the number of through holes is four, and the four through holes are symmetrical in pairs, with the center line of symmetry of the two symmetrical through holes coinciding with the center line of symmetry of the second metal part.

[0012] In one embodiment, the flat plate portion has a first forming hole at one end near the first connector, and the flat plate portion has a second forming hole at one end near the second connector.

[0013] In one embodiment, the second metal part has a plurality of first positioning holes.

[0014] In one embodiment, the flat plate portion has a plurality of second positioning holes, which are spaced apart along the central axis of the first metal part.

[0015] In one embodiment, the curved section has a first plastic connection hole, and the bent section has a second plastic connection hole.

[0018] Compared with the prior art, this application has at least the following advantages:

[0019] 1. The aforementioned anti-deformation communication equipment composite structure has symmetrically arranged through holes in the middle of the first metal part, which facilitates the mold support components to pass through the through holes and abut against the second metal part during the injection molding process, thereby preventing the second metal part from being deformed by the impact of molten plastic and ensuring structural stability.

[0020] 2. The two ends of the second metal part are formed into plastic connecting components by injection molding. At the same time, the end of the plastic component facing the flat plate is formed into a fixing post. The fixing post passes through the corresponding fixing hole to fix the second metal part to the first metal part, thereby enhancing the rigidity and stability of the overall structure and improving the assembly accuracy.

[0030] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0031] Please see Figures 2 to 5 This is an embodiment of the anti-deformation communication device composite structure 10, which includes a first metal part 100, a plastic connecting assembly 200, and a second metal part 300. The first metal part 100 includes a flat plate portion 110 and two side plate portions 120. The two side plate portions 120 are respectively located on both sides of the flat plate portion 110, and both side plate portions 120 are perpendicular to the flat plate portion 110. The flat plate portion 110 has a through hole 1101 and a fixing hole 1102. The through hole 1101 is located in the middle of the flat plate portion 110, and the fixing hole 1102 is located at both ends of the flat plate portion 110. The through hole 1101 is used for the support assembly to pass through during injection molding. The plastic connecting assembly 200 includes a first connecting member 210 and a second connecting member 220. Both the first connecting member 210 and the second connecting member 220 have a fixing post 230 on their side facing the flat plate portion 110. The fixing post 230 passes through a corresponding fixing hole 1102. The plastic connecting assembly 200 is an injection-molded integral structure. The second connecting assembly 220 is used to abut against the support assembly during injection molding. The second metal part 300 includes a straight section 310, a curved section 320, and a bent section 330. The two ends of the curved section 320 extend along the axis to form the straight section 310. The end of the straight section 310 away from the curved section 320 forms the bent section 330. The first connecting member 210 is located in the middle of the curved section 320, and the second connecting member 220 is located in the curved section 320. The second metal part 300 is fixedly connected to the first metal part 100 through the cooperation of the fixing post 230 and the fixing hole 1102. During injection molding, the support component of the injection mold abuts against the second metal part 300 through the through hole 1101.

[0032] Specifically, the thickness of the first metal part 100 is 0.5 mm, and the thickness of the second metal part 300 is 0.2 mm. The fixing posts 230 of the first connector 210 and the second connector 220 form mushroom heads after passing through the corresponding fixing holes 1102.

[0033] In this embodiment, the anti-deformation communication device composite structural component 10 has symmetrically arranged through holes 1101 in the middle of the first metal component 100. This allows the mold support components to pass through the through holes 1101 and abut against the second metal component 300 during injection molding, preventing the second metal component 300 from deforming due to the impact of molten plastic and ensuring structural stability. Simultaneously, plastic connecting components 200 are formed at both ends of the second metal component 300 through injection molding. A fixing post 230 is formed at the end of the plastic component facing the flat plate portion 110. The fixing post 230 passes through corresponding fixing holes 1102 to fix the second metal component 300 to the first metal component 100, enhancing the rigidity and stability of the overall structure and improving assembly accuracy.

[0034] like Figures 2 to 5 As shown, in one embodiment, there are four through holes 1101, which are symmetrically arranged in pairs. Specifically, in this embodiment, the through holes 1101 are rectangular and symmetrically arranged in pairs on the flat plate portion 110. During the injection molding process, the support assembly abuts against the second metal part 300 and forms a stable support structure with the support assembly at the other end, preventing the second metal part 300 from shifting or deforming due to the impact of molten plastic during the injection molding process. At the same time, the symmetrically arranged rectangular through holes 1101 are simple to process, facilitate mold positioning, and improve production efficiency.

[0035] like Figures 2 to 5 As shown, in one embodiment, the flat plate portion 110 has a first molding hole 1103 at the end near the first connecting member 210, and a second molding hole 1104 at the end near the second connecting member 220. Specifically, in this embodiment, the first molding hole 1103 is elongated, the second molding hole 1104 is rectangular, and there are two of both. During injection molding, one end of the molding component of the injection mold passes through the first molding hole 1103 and the second molding hole 1104, and together with the molding component at the other end, forms a cavity. It can be understood that by opening the first molding hole 1103 and the second molding hole 1104, the second metal part 300 is further abutted, preventing displacement or deformation of the second metal part 300 caused by the impact of molten plastic during injection molding, thus ensuring structural accuracy. In addition, the molding component of the injection mold and the molding hole cooperate to achieve a positioning function, ensuring that the first metal part 100 improves the stability of the injection molding process and the quality of the finished product.

[0036] like Figures 2 to 5As shown, in one embodiment, the second metal part 300 has multiple first positioning holes 301. Specifically, in this embodiment, the first positioning holes 301 are circular, and there are four first positioning holes 301. The four first positioning holes 301 are located at both ends of the straight section 310. During the injection molding process, the first positioning holes 301 cooperate with the positioning components of the injection mold to ensure that the second metal part 300 is accurately aligned and to prevent displacement during injection molding. In addition, during demolding, the positioning components drive the second metal part 300 to smoothly detach from the mold, avoiding structural deformation caused by external forces and ensuring the quality of the finished product.

[0037] like Figures 2 to 5 As shown, in one embodiment, the flat plate portion 110 has a plurality of second positioning holes 1105, which are spaced apart along the central axis of the first metal part 100. Specifically, in this embodiment, the second positioning holes 1105 are circular holes, and there are three of them. During injection molding, the second positioning holes 1105 cooperate with the positioning components of the injection mold to reduce the relative displacement between the first metal part 100 and the second metal part 300, ensuring precise alignment of each component and further improving the stability and service life of the overall structure. In addition, during demolding, the positioning components cooperating with the second positioning holes 1105 drive the first metal part 100 to rise synchronously, preventing the second metal part 300 from rising alone and causing structural misalignment or deformation.

[0038] like Figures 2 to 5 As shown, in one embodiment, the bending section 320 has a first plastic connection hole 3201, and the bending section 330 has a second plastic connection hole 3301. It can be understood that during the molding of the first connector 210, molten plastic fills the first plastic connection hole 3201, increasing the connection strength between the first connector 210 and the bending section 320. During the molding of the second connector 220, molten plastic fills the second plastic connection hole 3301, enhancing the bonding force between the second connector 220 and the bending section 330, ensuring the stability and durability of the overall structure, and extending product lifespan.

[0039] like Figures 2 to 5 As shown, in one embodiment, reinforcing ribs 211 are formed on both sides of the first connector 210, and a reinforcing block 221 is formed at the end of the second connector 220 opposite to the first connector 210. It is understood that by providing reinforcing structures in the first connector 210 and the second connector 220, the structural strength can be effectively improved, stress concentration can be avoided, and the plastic connector assembly 200 can be ensured to be less prone to deformation. Furthermore, the reinforcing ribs 211 and reinforcing block 221 added during the injection molding process help reduce the occurrence of injection molding defects.

[0040] A communication device includes an antenna element, a heat sink, a sealed housing, and a deformation-resistant composite structural component 10 as described in any of the above embodiments. In this embodiment, by employing the deformation-resistant composite structural component 10, the communication device avoids signal interference and equipment damage caused by deformation of metal parts, thereby improving the reliability and service life of the communication device.

[0041] Compared with the prior art, this application has at least the following advantages:

[0042] 1. The aforementioned anti-deformation communication equipment composite structure has symmetrically arranged through holes in the middle of the first metal part, which facilitates the mold support components to pass through the through holes and abut against the second metal part during the injection molding process, thereby preventing the second metal part from being deformed by the impact of molten plastic and ensuring structural stability.

[0043] 2. The two ends of the second metal part are formed into plastic connecting components by injection molding. At the same time, a fixing post is formed at the end of the plastic component facing the flat plate. The fixing post passes through the corresponding fixing hole to fix the second metal part to the first metal part, thereby enhancing the rigidity and stability of the overall structure and improving the assembly accuracy.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
