Description

Technical Field

[0001] This application relates to the technical field of sound mesh implantation sealing molds, and more specifically, to a sound mesh implantation sealing mold. Background Technology

[0002] In existing technology, the sound mesh is directly implanted into the mold during the molding process. During implantation, air suction is used to fix the sound mesh to the mold, and then plastic is injected to wrap and fix the sound mesh. However, the mold actually has a certain amount of pre-compression after the sound mesh is implanted. This pre-compression has gaps. If the sound mesh shifts or is missing during the plastic injection process, it will cause the sound mesh suction hole to overflow / swish. On-site fitters have to go off the machine frequently for maintenance, which will cause damage to the mold. The machining cost is high and the production efficiency is low. Summary of the Invention

[0003] This application provides a sealing mold for sound mesh implantation to solve the problems of glue overflow and runoff during the injection molding process of sound mesh in the prior art.

[0004] The sound mesh implant sealing mold of this application includes: a mold body assembly, which includes a pad structure, a first template structure and a second template structure, the first template structure being located between the second template structure and the pad structure, and the first template structure having an air-sealing hole; and a sealing assembly, which includes a first transmission component, a lever structure, a second transmission component and an air-sealing needle, the first end of the first transmission component passing through the first template structure and abutting against the second template structure, the first transmission component cooperating with the first side of the lever structure, the second end of the lever structure cooperating with the second transmission component, and the air-sealing needle cooperating with the second transmission component, the air-sealing needle being movably inserted into the air-sealing hole.

[0005] Furthermore, the second transmission component includes a transmission plate and a guide post. The guide post is fixed on the transmission plate. The first template structure has a guide hole, and the guide post is partially inserted into the guide hole. The air-locking needle is fixed on the transmission plate.

[0006] Furthermore, the transmission plate includes a first transmission plate and a second transmission plate stacked together. The first transmission plate is located between the pad structure and the second transmission plate. The first transmission plate has a first groove. The guide post includes a guide post body and a limiting rod. The first end of the guide post body is fixedly connected to the limiting rod. The limiting rod is located in the first groove. The second transmission plate abuts against the limiting rod.

[0007] Furthermore, the second transmission component also includes a return spring, which is sleeved on the circumferential outer side of the guide post body. The first end of the return spring abuts against the second transmission plate, and the second end of the return spring abuts against the first template structure.

[0008] Furthermore, the guide posts and return springs are provided in multiple corresponding configurations.

[0009] Furthermore, the air-locking needles include multiple air-locking needles, and the air-locking holes correspond one-to-one with the multiple air-locking needles. Each air-locking needle includes a first rod segment, a transition rod segment, and a second rod segment. The transition rod segment connects the first rod segment and the second rod segment. The first rod segment is located on the side away from the second template structure, and the diameter of the first rod segment is larger than the diameter of the second rod segment. The first end of the transition rod segment has the same diameter as the first rod segment, and the second end of the transition rod segment has the same diameter as the second rod segment. The air-locking holes have a first air-locking hole segment, a transition hole segment, and a second air-locking hole segment. The first air-locking hole segment is adapted to the first rod segment, the transition rod segment is adapted to the transition hole segment, and the second air-locking hole segment is adapted to the second rod segment.

[0010] Furthermore, an air passage is provided on the side wall of the air-closing hole, and the air passage is located in the second air-closing hole section.

[0011] Furthermore, the lever structure includes a rotating shaft and a rotating block. The rotating shaft is mounted on the pad structure, and the rotating block is connected to the rotating shaft. The rotating block has a clearance groove on one side of the transmission plate. When the transmission plate presses down against the rotating block, the edge of the transmission plate is located in the clearance groove.

[0012] Furthermore, there are multiple first transmission components and lever structures, which are arranged in a one-to-one correspondence, and the multiple lever structures correspond to different positions of the second transmission component.

[0013] Furthermore, the pad structure has a second groove, and the lever structure is rotatably disposed within the second groove.

[0014] Using the technical solution of this application, the sound mesh to be processed is placed on the first template structure, and the second template structure is placed on the first template structure. The second template structure presses against the first transmission component, the first transmission component presses against the lever structure, and the lever structure pries the second transmission component. The second transmission component drives the air-sealing needle to seal the air-sealing hole, and then the glue injection is performed. Because the air-sealing needle seals the air-sealing hole, there is no problem of glue overflow or splashing. The technical solution of this application effectively solves the problems of glue overflow and splashing during the injection of plastic in the prior art when processing sound mesh.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0028] like Figures 1 to 6 As shown, the sound mesh implant sealing mold of this embodiment includes: a mold body assembly 10 and a sealing assembly 20. The mold body assembly 10 includes a pad structure 11, a first template structure 12 and a second template structure 13. The first template structure 12 is located between the second template structure 13 and the pad structure 11, and the first template structure 12 has an air-sealing hole. The sealing assembly 20 includes a first transmission member 21, a lever structure 22, a second transmission member 23 and an air-sealing needle 24. The first end of the first transmission member 21 passes through the first template structure 12 and abuts against the second template structure 13. The first transmission member 21 cooperates with the first side of the lever structure 22. The second end of the lever structure 22 cooperates with the second transmission member 23. The air-sealing needle 24 cooperates with the second transmission member 23 and is movably inserted into the air-sealing hole.

[0029] Applying the technical solution of this embodiment, the sound mesh to be processed is placed on the first template structure 12, and the second template structure 13 is placed on the first template structure 12. The second template structure 13 presses against the first transmission member 21, and the first transmission member 21 presses against the lever structure 22. The lever structure 22 pries the second transmission member 23, and the second transmission member 23 drives the air-sealing needle 24 to seal the air-sealing hole. Then, the glue injection is performed. Because the air-sealing needle 24 seals the air-sealing hole, there will be no problem of glue overflow or flow. The technical solution of this embodiment effectively solves the problem of glue overflow and flow during the injection of plastic in the processing of sound mesh in the prior art.

[0030] like Figure 4 and Figure 5As shown, in this embodiment, the second transmission component 23 includes a transmission plate 231 and a guide post 232. The guide post 232 is fixed on the transmission plate 231. The first template structure 12 has a guide hole, and the guide post 232 partially passes through the guide hole. The air-sealing needle 24 is fixed on the transmission plate 231. The structure of the transmission plate 231 results in a large working area and greater stability. The guide post 232 effectively guides the transmission plate 231, ensuring that it moves along a predetermined trajectory.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, the transmission plate 231 includes a first transmission plate 2311 and a second transmission plate 2312 stacked together. The first transmission plate 2311 is located between the pad structure 11 and the second transmission plate 2312. The first transmission plate 2311 has a first groove. The guide post 232 includes a guide post body and a limiting rod. The first end of the guide post body is fixedly connected to the limiting rod, which is located in the first groove. The second transmission plate 2312 presses against the limiting rod. The structure of the first transmission plate 2311 with the first groove makes the structure compact and easy to install. The setting of the limiting rod facilitates the installation and fixing of the guide post 232. It should be noted that the first transmission plate 2311 and the second transmission plate 2312 have a mutually cooperating limiting structure, which prevents the first transmission plate 2311 and the second transmission plate 2312 from misalignment. In the technical solution of this embodiment, the limiting structure consists of a limiting protrusion and a limiting groove. The first transmission plate 2311 is provided with a limiting protrusion extending toward the second transmission plate 2312, resulting in a compact structure.

[0032] like Figure 4 and Figure 5 As shown, in this embodiment, the second transmission component 23 further includes a return spring 233. The return spring 233 is sleeved on the circumferential outer side of the guide post body. The first end of the return spring 233 abuts against the second transmission plate, and the second end of the return spring 233 abuts against the first template structure 12. The arrangement of the return spring 233 allows the sealing assembly 20 to automatically reset. This structure reduces manual operation and improves the linkage effect. It should be noted that, in order to prevent the return spring 233 from being misaligned, a first spring groove is provided on the second transmission plate, and a second spring groove is provided on the first template structure 12. The above structure can effectively prevent the return spring from leaving its original position, thereby ensuring that the force on the first template structure 12 is relatively accurate.

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, multiple guide posts 232 and reset springs 233 are provided in a one-to-one correspondence. This structure ensures that the first template structure 12 experiences relatively balanced forces.

[0034] like Figure 5 and Figure 6 As shown, in this embodiment, the air-sealing needle 24 includes multiple air-sealing needles 24, and the air-sealing holes correspond one-to-one with each of the multiple air-sealing needles 24. Each air-sealing needle 24 includes a first rod segment 241, a transition rod segment 242, and a second rod segment 243. The transition rod segment 242 connects between the first rod segment 241 and the second rod segment 243. The first rod segment 241 is located on the side away from the second template structure 13, and its diameter is larger than that of the second rod segment 243. The first end of the transition rod segment 242 has the same diameter as the first rod segment 241, and its second end has the same diameter as the second rod segment 243. The air-sealing hole has a first air-sealing hole segment, a transition hole segment, and a second air-sealing hole segment. The first air-sealing hole segment is adapted to the first rod segment 241, the transition rod segment 242 is adapted to the transition hole segment, and the second air-sealing hole segment is adapted to the second rod segment 243. This structure easily forms a seal. It should be noted that the first segment 241 has the same diameter, the second segment 243 has the same diameter, and the transition segment 242 is shaped like a frustum conical.

[0035] In this embodiment, the sidewall of the air-sealing hole is provided with an air passage, which is located in the second air-sealing hole section. This structure facilitates sealing. It should be noted that when the second template structure 13 opens, the second rod section avoids the air passage; when the second template structure 13 closes, the second rod section blocks the air passage. Figure 5 There are 8 air-sealing pins 24 in the mold (one set of main mold component 10, two sets of sealing components 20). The number of air-sealing pins 24 can also be set to other quantities as needed. Other openings and grooves in the sound mesh implantation sealing in this embodiment are made according to the needs of sealing flow. Some vulnerable parts or parts that are difficult to process can be set as inlay structures, which will not be described in detail here.

[0036] like Figure 4 and Figure 5As shown, in this embodiment, the lever structure 22 includes a rotating shaft 221 and a rotating block 222. The rotating shaft 221 is mounted on the pad structure 11, and the rotating block 222 is connected to the rotating shaft. The rotating block 222 has a clearance groove on one side supporting the transmission plate 231. When the transmission plate 231 presses down against the rotating block, the edge of the transmission plate 231 is located within the clearance groove. The arrangement of the rotating shaft 221 and the rotating block 222 is relatively compact. It should be noted that the rotating shaft 221 and the rotating block 222 of the lever structure 22 can be integrally formed, so that the rotating shaft and the pad structure 11 can rotate relative to each other. It should also be noted that, for ease of installation, the pad structure 11 in this embodiment is a split structure, including a pad and a pressure plate, with the rotating shaft located between the pad and the pressure plate. In other embodiments, the rotating shaft 221 and the rotating block 222 can be separate, the rotating block 222 can rotate relative to the rotating shaft 221, or the rotating shaft 221 can be fixed in the pad structure 11.

[0037] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, there are multiple first transmission components 21 and lever structures 22, which are arranged in a one-to-one correspondence. The multiple lever structures 22 correspond to different positions of the second transmission component 23. The above structure ensures that the transmission plate 231 is subjected to relatively balanced forces.

[0038] like Figure 3 As shown, in this embodiment, the pad structure 11 has a second groove, and the lever structure 22 is rotatably disposed within the second groove. The above structure is compact, and the lever structure 22 is less prone to misalignment.

[0039] It should be noted that, in order to improve efficiency, one set of mold main body assembly 10 in this application can correspond to multiple sets of sealing assemblies 20. In this embodiment, two sets of sealing assemblies 20 are provided on one set of mold main body assembly 10. The first transmission component 21 is a return rod, and the first template structure 12 has a through hole, in which the return rod passes. The same set of sealing assemblies 20 can process two sound meshes.

[0040] As described above, sound mesh implantation requires a certain air pressure to adhere the sound mesh to the mold. In this embodiment, after the injection mold is closed, the mold holds the sound mesh in place to prevent it from shifting. Simultaneously, an air-sealing needle 24 blocks the air intake hole (air-sealing hole) inside the mold, preventing plastic from flowing into the air intake hole if the sound mesh shifts or is missing during molding. This reduces the risk of mold damage and improves production efficiency. The precision sound mesh implantation and sealing technology breaks with convention, ensuring that even if the sound mesh shifts or is missing during plastic injection, it will not cause plastic overflow or flow into the sound mesh's air intake hole. This changes the traditional method of implanting sound mesh in the mold, reducing mold damage and increasing production efficiency.

[0041] A series of verifications were conducted during the implementation of this embodiment, overcoming the mold overflow / explosion problems in sound mesh implantation molding. We have accumulated rich experience in dealing with such problems. Other acoustic products can also adopt sound mesh precision implantation and sealing technology to improve production efficiency and reduce mold maintenance costs.
