Description

Technical Field

[0001] This application relates to the technical field of audio mesh implantation pre-compression molds, and more specifically, to an audio mesh implantation pre-compression mold. Background Technology

[0002] Traditional sound mesh manufacturing involves gluing the mesh to the sound outlet, a process that is inefficient. Furthermore, during use, the mesh can detach due to glue aging, sound airflow, and vibration, leading to malfunction.

[0003] In recent years, the sound mesh implantation technology has been used to directly implant the sound mesh into the mold during the molding process and fix it with plastic. This has changed the traditional assembly line method of gluing the sound mesh. Since the sound mesh needs to be bent during the mold closing process, without external intervention, the bending will pull the sound mesh and make it shake unstable in the mold cavity, resulting in the finished sound mesh shifting and a high defect rate. Summary of the Invention

[0004] This application provides a pre-compression mold for implanting sound mesh to solve the problem of high defect rate caused by sound mesh shaking in the mold cavity during bending in the prior art.

[0005] The sound mesh implantation pre-compression mold of this application includes: a mold body assembly, which includes a first mold core structure and a second mold core structure, the first mold core structure and the second mold core structure being stacked; a linkage assembly, which includes a driving component, a linkage structure, a locking structure and a pre-compression component, the driving component being at least partially disposed within the first mold core structure, the linkage structure being disposed within the first mold core structure and connected to the driving component, the pre-compression component being fixedly connected to the linkage structure, the locking structure being fixed within the first mold core structure, the linkage structure and the locking structure having a matching pre-compression position and an ejection position; and a pressing assembly, which is at least partially movably disposed within the second mold core structure.

[0006] Furthermore, the linkage structure includes a reset plate, which includes a first plate segment and a second plate segment. The first plate segment is connected to the driving component, the pre-pressing component is fixed together with the first plate segment, the second plate segment is fixedly connected to the first plate segment, the second plate segment extends towards the direction of the second mold core structure, and the second plate segment cooperates with the locking structure for locking.

[0007] Furthermore, the locking structure includes a locking fixing block, a first elastic element, and a locking pin. The locking fixing block is fixed inside the first mold core structure. The side wall of the locking fixing block adjacent to the second plate segment has a groove. The first elastic element is disposed in the groove. The first end of the first elastic element abuts against the inner wall of the groove, and the second end of the first elastic element abuts against the locking pin. The locking pin is locked to the second plate segment.

[0008] Furthermore, the side of the locking pin facing the second plate segment has a locking protrusion, and the side of the second plate segment facing the locking pin has multiple locking grooves, each of which can engage with the locking protrusion.

[0009] Furthermore, the linkage structure also includes a cover plate, which is located on the side of the first plate segment away from the second plate segment.

[0010] Furthermore, the reset plate has a groove on the side facing the cover plate, and the pre-compression component includes a needle body and a fixing part connected to the first end of the needle body. The fixing part is located in the groove, and the needle body passes through the first plate segment.

[0011] Furthermore, the pressing component includes a bending insert fixing block and a bending insert, the bending insert fixing block being located within the second mold core structure, and the bending insert being inserted through the bending insert fixing block.

[0012] Furthermore, the first end of the bent insert has a raised edge, the bent insert fixing block has a limiting step that matches the raised edge, and the second end of the bent insert abuts against the sound mesh.

[0013] Furthermore, the pressing assembly also includes a front mold insert fixing block and a front mold insert. The front mold insert fixing block is located within the second mold core structure and between the bending insert fixing block and the first mold core structure. The front mold insert is located within the front mold insert fixing block.

[0014] Furthermore, the pressing assembly also includes a second elastic element. The side of the front mold insert fixing block facing the bending insert fixing block has an elastic element groove. The first end of the second elastic element abuts against the bottom wall of the elastic element groove, and the first end of the second elastic element abuts against the side of the bending insert fixing block facing the front mold insert fixing block.

[0015] By applying the technical solution of this application, after the sound mesh to be processed is placed, the driving component is pushed, which drives the linkage structure to move. The linkage structure cooperates with the locking structure to lock and fix it in place. The linkage structure drives the pre-pressing component to move, and the pre-pressing component presses against the sound mesh. Then, a force is applied to the second mold core structure towards the first mold core structure, and the second mold core structure presses against the sound mesh, thus completing the processing of the sound mesh. Because the pre-pressing component pre-presses and fixes the sound mesh, the problem of high processing defect rate caused by misalignment or shaking of the sound mesh is avoided. The technical solution of this application effectively solves the problem of high defect rate caused by the sound mesh shaking in the mold cavity during bending in the prior art.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figures 1 to 6 As shown, the pre-compression mold for sound mesh implantation in this embodiment includes: a mold body assembly 10, a linkage assembly 20, and a pressing assembly 30. The mold body assembly 10 includes a first mold core structure 11 and a second mold core structure 12, which are stacked. The linkage assembly 20 includes a drive member 21, a linkage structure 22, a locking structure 23, and a pre-compression member 24. The drive member 21 is at least partially disposed within the first mold core structure 11, the linkage structure 22 is disposed within the first mold core structure 11 and connected to the drive member 21, the pre-compression member 24 is fixedly connected to the linkage structure 22, and the locking structure 23 is fixed within the first mold core structure 11. The linkage structure 22 and the locking structure 23 have a matching pre-compression position and an ejection position. The pressing assembly 30 is at least partially movably disposed within the second mold core structure 12.

[0030] Applying the technical solution of this embodiment, after the sound mesh 100 to be processed is placed, the driving component 21 is pushed, which drives the linkage structure 22 to move. The linkage structure 22 cooperates with the locking structure 23 to lock and fix it in place. The linkage structure 22 drives the pre-pressing component 24 to move, and the pre-pressing component 24 presses against the sound mesh 100. Then, a force is applied to the second mold core structure 12 towards the first mold core structure 11, and the second mold core structure 12 presses against the sound mesh 100, thus completing the processing of the sound mesh 100. Because the pre-pressing component 24 pre-presses and fixes the sound mesh 100, the problem of high processing defect rate caused by misalignment or shaking of the sound mesh 100 is avoided. The technical solution of this embodiment effectively solves the problem of high defect rate caused by the sound mesh 100 shaking in the mold cavity when bending the sound mesh 100 in the prior art.

[0031] like Figure 4 and Figure 6As shown, in the technical solution of this embodiment, the linkage structure 22 includes a reset plate 221, which includes a first plate segment and a second plate segment. The first plate segment is connected to the driving member 21, and the pre-pressing member 24 is fixed to the first plate segment. The second plate segment is fixedly connected to the first plate segment and extends towards the second mold core structure 12. The second plate segment cooperates with the locking structure 23 for locking. The above structure facilitates linkage. It should be noted that the first plate segment and the second plate segment are integrally formed structures. Through the structural design of the reset plate 221, the locking and linkage with the pre-pressing member 24 are cleverly achieved.

[0032] like Figures 4 to 6 As shown, in this embodiment, the locking structure 23 includes a locking fixing block 231, a first elastic element 232, and a locking pin 233. The locking fixing block 231 is fixed inside the first mold core structure 11. The side wall of the locking fixing block 231 adjacent to the second plate segment has a groove. The first elastic element 232 is disposed in the groove. The first end of the first elastic element 232 abuts against the inner wall of the groove, and the second end of the first elastic element 232 abuts against the locking pin 233. The locking pin 233 is locked to the second plate segment. The above structure is compact and highly operable. The first elastic element 232 ensures the automatic return of the locking pin 233. It should be noted that the first elastic element 232 is a spring.

[0033] like Figures 4 to 6 As shown, in the technical solution of this embodiment, the locking pin 233 has a locking protrusion on the side facing the second plate segment, and the second plate segment has multiple locking grooves 222 on the side facing the locking pin 233, each of which can engage with the locking protrusion. The above structure is compact. It should be noted that in the technical solution of this embodiment, there are two locking grooves 222, and the distance between the two locking grooves 222 is 2.5mm. The locking pin 233 includes a limiting post and a pressing plate. The limiting post passes through the first elastic element 232, which is a spring. The spring abuts against the pressing plate, and the other side of the pressing plate is provided as a locking protrusion. The locking protrusion is a tapered shape that gradually tapers from the direction close to the pressing plate to the direction far away from the pressing plate, which facilitates locking and sliding. It should be noted that the locking protrusion has two states: an open mold state and a closed mold state. The locking protrusion and... Figure 6 When the lower slot 222 engages, the pre-compression mold for the sound mesh is in the open state, and the pre-compression component 24 pre-compresses the sound mesh 100; the protrusion and... Figure 6When the higher slot 222 is engaged, the pre-compression mold for inserting the sound mesh is in the closed state. During the processing of the sound mesh 100, the pre-compression mold for inserting the sound mesh is less prone to displacement and shaking. The front mold insert is inside the front mold insert fixing block. Driven by the second elastic element 33, the front mold insert fixing block (front mold insert jumper) floats 0.55mm to form a flat cavity, and the sound mesh 100 is inserted into the mold cavity. In the mold-opening state, the reset plate 221, the pre-compression pin (pre-compression part 24), and the pre-compression pin cover plate (cover plate) move 2.50mm under the drive of the drive rod (drive part 21). At the same time, the positioning jump pin (locking pin 233) falls from the reset plate 221 into the next V-groove (locking groove 222) under the drive of the positioning jump pin drive spring (second elastic part 33), supporting the pre-compression pin of the sound mesh, which is 2.50mm higher than the mold surface. During the mold closing process, before the sound mesh is bent, the pre-compression pin pre-compresses the sound mesh in advance, which plays a fixing role and prevents the sound mesh from being pulled and shifted during the bending process due to lack of pre-compression.

[0034] In the mold-closed state, under the pressure of the front mold insert plate, the reset plate drives the sound mesh pre-pressure pin and the sound mesh pre-pressure pin cover plate to reset, and the entire mold opening and closing action is completed.

[0035] Before mold closing, the pre-pressing pin of the sound mesh is pushed by the drive rod and pre-exceeds the mold surface by 2.5mm. During the mold closing process, the pre-pressing pin of the sound mesh first fixes the sound mesh to prevent the sound mesh from shifting in the mold cavity during the mold closing process.

[0036] like Figure 5 As shown, in the technical solution of this embodiment, the linkage structure 22 further includes a cover plate, which is disposed on the side of the first plate segment away from the second plate segment. The cover plate facilitates the connection with the driving member 21 and the fixing of the pre-compression member 24.

[0037] like Figures 4 to 6 As shown, in this embodiment, the reset plate 221 has a groove on the side facing the cover plate. The pre-compression member 24 includes a needle body and a fixing part connected to the first end of the needle body. The fixing part is located in the groove, and the needle body passes through the first plate segment. The above structure is compact and facilitates the fixing of the pre-compression member 24. It should be noted that the second end of the needle body abuts against the fixed sound mesh, and the cover plate is connected to the first plate segment by fasteners.

[0038] In this embodiment, the pressing component 30 includes a bending insert fixing block 31 and a bending insert 32. The bending insert fixing block 31 is located within the second mold core structure 12, and the bending insert 32 passes through the bending insert fixing block 31. The bending insert fixing block 31 facilitates the fixing of the bending insert 32. The bending insert 32 is a rod-shaped structure, and it achieves the pressing and bending of the sound mesh 100 (the bending mentioned above refers to one type, and it can also be bending or other operations).

[0039] In this embodiment, the first end of the bent insert has a raised edge, the bent insert fixing block 31 has a limiting step that cooperates with the raised edge, and the second end of the bent insert 32 abuts against the sound mesh. The above structure achieves the limiting of the bent insert 32, thereby ensuring that the sound mesh 100 is not prone to over-bending.

[0040] In this embodiment, the pressing component 30 further includes a front mold insert fixing block and a front mold insert. The front mold insert fixing block is located within the second mold core structure 12 and between the bending insert fixing block and the first mold core structure 11. The front mold insert is located within the front mold insert fixing block. The front mold insert fixing block facilitates the installation of the front mold insert, and the front mold insert effectively presses against the sound mesh 100.

[0041] In this embodiment, the pressing component 30 further includes a second elastic element 33. The side of the front mold insert fixing block facing the bending insert fixing block has an elastic element groove. The first end of the second elastic element 33 abuts against the bottom wall of the elastic element groove, and the first end of the second elastic element 33 abuts against the side of the bending insert fixing block facing the front mold insert fixing block. This structure ensures a certain buffering force when a force is applied to the pressing component 30. It should be noted that the elasticity of the second elastic element 33 on the bending insert fixing block 31 ensures that the gap between the bending insert fixing block 31 and the front mold insert fixing block is 0.55mm.
