When multiple earphone shell shells are demolded at the same time, the temperature of the Bluetooth headset shell shell may be high and they may stick to each other, thereby causing the possibility of damage to the earphone shell. Summary of the invention

[0006] By adopting the above technical solution, when the staff manufactures the earphone shell, the staff first fixes the molding module to the molding support module through the fixing assembly, and then connects the input pipe and the inlet pipe, and the output pipe and the outlet pipe through two sets of connecting assemblies, and then starts the driving pump. The condensate in the cooling box circulates in the cooling pipe driven by the driving pump, absorbs the heat of the earphone shell, and accelerates the molding efficiency of the earphone shell. The condensate after absorbing heat returns to the cooling box and is accelerated to dissipate the heat of the condensate in the cooling box under the action of the heat dissipation assembly, thereby accelerating the cooling effect of the earphone shell, improving the cooling and molding efficiency of the earphone shell, and reducing the possibility of adhesion during demolding.

[0007] Preferably, the connecting component includes an electromagnet and a control component, the control component can control the power-on state of the electromagnet, the inlet pipe and the outlet pipe are made of magnetic metal, the inner wall of the forming support mold and the inner wall of the mold main bin are provided with connecting grooves along the same straight line, the input pipe is passed through and slides in the connecting groove, the electromagnet is fixedly sleeved on the outer wall of the input pipe, and a reset component for resetting the input pipe is arranged in the connecting groove; the input pipe is inserted into the inlet pipe, the electromagnet abuts against the inlet pipe, and a sealing component for sealing the input pipe is arranged in the inlet pipe.

[0008] By adopting the above technical solution, the staff fixes the molding module to the molding support module through the fixing component, and fixes the position so that the inlet pipe and the input pipe are aligned. At this time, the staff controls the electromagnet through the control component. The electromagnet has magnetism and moves toward the inlet pipe. The movement of the electromagnet drives the input pipe to be inserted into the inlet pipe, and the electromagnet abuts against the inlet pipe port. The sealing component seals the interface, so that the condensate can flow into the cooling pipe in the cooling chamber to cool the earphone shell.

[0010] By adopting the above technical solution, when the staff needs to drive the molding module to rotate for demolding, the staff needs to disconnect the connection between the inlet pipe and the input pipe. At this time, the staff disconnects the magnetism of the electromagnet through the control block, and the electromagnet moves toward the connecting block under the elastic force of the reset spring.

[0012] By adopting the above technical solution, when the mold on the molding module is in the process of being made, the fixed block is inserted into the fixed groove. When the mold needs to be demolded after cooling, the staff pulls the pulling block to pull the fixed block to compress the first spring and move it away from the molding module. Then the staff rotates the molding module for demolding. When the molding module is rotated, the side wall of the molding module is fixedly abutted against the fixed block so that the fixed block is in the storage groove. When the molding module is rotated to its original position, the fixed groove is aligned with the fixed block. At this time, the fixed block is inserted into the fixed groove under the action of the first spring, which limits the offset of the molding module, thereby facilitating the alignment of the input pipe and the inlet pipe.

[0014] By adopting the above technical solution, when the input tube is inserted into the inlet tube, the input tube is inserted into the bucket-shaped sleeve. As the electromagnet gradually approaches the inlet tube, the input tube is gradually inserted deeper into the bucket-shaped sleeve. When the electromagnet abuts against the inlet tube, the magnetic ring in the slot attracts the bucket-shaped sleeve to move into the slot, thereby moving the bucket-shaped sleeve toward the end with a larger diameter of the input tube, so that the bucket-shaped sleeve is clamped on the peripheral side wall of the input tube, thereby making the connection between the input tube and the inlet tube sealed, reducing the overflow of condensate from the connection.

[0015] Preferably, one end of the bucket-shaped sleeve away from the magnetic ring is fixedly connected with a rubber ring, and the rubber ring abuts against the peripheral side wall of the input pipe.

[0016] By adopting the above technical solution, the rubber ring can improve the sealing strength between the bucket-shaped sleeve and the input pipe.

[0020] By adopting the above technical solution, the condensate with heat flowing out of the molding module passes through the cooling pipe on the side wall of the mold main chamber and enters the cooling box.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the staff is manufacturing the earphone shell, the staff first fixes the molding mold to the molding support mold through the fixing assembly, and then connects the input pipe with the inlet pipe and the output pipe with the outlet pipe through two sets of connecting assemblies, and then starts the driving pump.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] The present application embodiment discloses a molding die for a Bluetooth headset housing, such as Figure 1 and Figure 2 As shown, it includes a mold main chamber 1, a molding support mold 2 and a molding module 3. The molding support mold 2 is slidably connected to the mold main chamber 1, and the molding module 3 is rotatably connected to the molding support mold 2. A cooling cavity is provided in the molding module 3, and a cooling pipe 4 is arranged in the cooling cavity. The cooling pipe 4 is folded and wound in the cooling cavity, thereby increasing the contact area between the cooling pipe 4 and the molding module 3, thereby accelerating the heat dissipation effect of the molding module 3. The two ends of the cooling pipe 4 are fixedly welded with an inlet pipe 5 and an outlet pipe 6. The inlet pipe 5 and the outlet pipe 6 are made of magnetic metal. The cooling pipe 4 and the inlet pipe 5 and the outlet pipe 6 are clamped in a cooling cavity and are not easy to move.

[0032] like Figure 3 and Figure 4 As shown, the inner wall of the forming support mold 2 and the inner wall of the adjacent mold main chamber 1 are provided with a connection groove 16 along the same straight line, and there are two connection grooves 16, the input pipe 7 and the output pipe 8 are respectively passed through the two connection grooves 16, and the input pipe 7 and the output pipe 8 are both provided with a control valve 34, and a cooling box 9 is provided next to the mold main chamber 1. The cooling box 9 contains condensate, and the input pipe 7 and the output pipe 8 are both connected to the cooling box 9 through the cooling pipe 4. The cooling box 9 is provided with a driving pump 10 for driving the condensate to flow, and the cooling box 9 is provided with a heat dissipation component 11 for dissipating heat from the condensate. The forming support mold 2 is provided with a fixing component 12 for fixing the forming mold, and the mold main chamber 1 is provided with two groups of connecting components 13 for connecting the input pipe 7 with the inlet pipe 5 and the output pipe 8 with the outlet pipe 6.

[0033] like Figure 3 and Figure 4As shown, the two groups of connection components 13 are consistent. In this embodiment, only the connection component 13 between the inlet pipe 5 and the input pipe 7 is briefly described. The connection component 13 includes an electromagnet 14 and a control member 15. The electromagnet 14 is annular and fixedly welded on the side wall of the input pipe 7. The control member 15 is fixedly installed on the molding module 3. The control member 15 can control the power-on state of the electromagnet 14. The input pipe 7 is driven to be inserted into the inlet pipe 5 for connection through the attraction between the specific magnetism of the electromagnet 14 and the inlet pipe 5. A sealing component 18 for sealing the input pipe 7 is arranged in the inlet pipe 5. A reset component 17 for keeping the input pipe 7 away from the inlet pipe 5 is arranged in the connection groove 16. The sealing component 18 includes a bucket-shaped sleeve 26 and a magnetic ring 27. The diameter of the bucket-shaped sleeve 26 increases from the inside to the outside. A slide groove 35 is opened on the inner wall of the inlet pipe 5. The slide groove 35 extends in an inclined direction. A slider 36 is fixedly welded on the side wall of the bucket-shaped sleeve 26. The cooperation between the slider 36 and the slide groove 35 can limit the moving range of the bucket-shaped sleeve 26. The end surface of the electromagnet 14 near the bucket-shaped sleeve 26 is provided with a slot, the slot is in the shape of a ring, the magnetic ring 27 is fixedly welded in the slot, the bucket-shaped sleeve 26 and the magnetic ring 27 attract each other, and the end of the bucket-shaped sleeve 26 with the largest diameter is inserted into the slot under the attraction of magnetic force. The diameter of the input pipe 7 increases from the port to the connection near the cooling pipe 4, and the end of the bucket-shaped sleeve 26 away from the magnetic ring 27 is fixedly connected with a rubber ring 28, and the rubber ring 28 is tightly pressed against the side wall of the input pipe 7.

[0034] like Figure 3 and Figure 4 As shown, combined with Figure 5 As shown, the reset assembly 17 includes a connecting block 19 and a reset spring 20, the connecting pipe 33 is cylindrical, the connecting block 19 is sleeved on the input pipe 7, the connecting block 19 is fixedly welded to the inner wall of the connecting groove 16, the reset spring 20 is sleeved on the input pipe 7 and its two ends are respectively fixedly welded to the electromagnet 14 and the opposite side walls of the connecting block 19. The fixing assembly 12 includes a fixing block 21, a first spring 23 and a pull block 22, the forming support mold 2 is provided with a storage groove 25 in the horizontal direction, the fixing block 21 slides in the storage groove 25 in the horizontal direction, the side wall of the forming mold 3 is provided with a fixing groove 24 for the fixing block 21 to be inserted, the two ends of the first spring 23 are respectively fixedly welded to the fixing block 21 and the inner wall of the storage groove 25, the pull block 22 is fixedly welded to the top of the fixing block 21, and the pull block 22 is penetrated and slides on the forming support mold 2.

[0035] like Figure 5As shown, when the earphone shell on the molding module 3 is in the process of being made, the fixing block 21 is inserted into the fixing groove 24. When the mold needs to be demolded after cooling, the staff pulls the pull block 22 to drive the fixing block 21 to compress the first spring 23 and move it away from the molding module 3. Then the staff rotates the molding module 3 for demolding. When the molding module 3 is rotated, the side wall of the molding module 3 slides and abuts against the fixing block 21 so that the fixing block 21 is in the storage groove 25. When the molding module 3 rotates to its original position, the fixing groove 24 is aligned with the fixing block 21. At this time, the fixing block 21 is inserted into the fixing groove 24 under the action of the first spring 23, which limits the displacement of the molding module 3. At the same time, the positions of the inlet pipe 5 and the input pipe 7 are aligned to play a guiding role.

[0036] like Figure 3 and Figure 5 As shown, the fixing assembly 12 makes the inlet pipe 5 and the input pipe 7 aligned. At this time, the staff controls the electromagnet 14 through the control member 15. The electromagnet 14 has magnetism. The electromagnet 14 moves toward the inlet pipe 5 due to the magnetic attraction. The movement of the electromagnet 14 drives the input pipe 7 to be inserted into the inlet pipe 5. The input pipe 7 is inserted into the bucket-shaped sleeve 26. As the electromagnet 14 gradually approaches the inlet pipe 5, the input pipe 7 gradually penetrates into the bucket-shaped sleeve 26, and the electromagnet 14 abuts against the port of the inlet pipe 5. At this time, the magnetic ring 27 in the slot attracts the bucket-shaped sleeve 26 to move into the slot, so that the bucket-shaped sleeve 26 moves toward the end with a larger diameter of the input pipe 7, so that the rubber ring 28 in the end with a smaller diameter of the bucket-shaped sleeve 26 is clamped on the side wall of the input pipe 7, thereby making the connection between the input pipe 7 and the inlet pipe 5 sealed. The rubber ring 28 can improve the sealing strength between the bucket-shaped sleeve 26 and the input pipe 7, and reduce the possibility of condensate overflowing from the connection. Next, the staff opens the control valve 34 and starts the driving pump 10 in the cooling box 9. The condensed liquid in the cooling box 9 circulates in the cooling pipe 4 driven by the driving pump 10, absorbs the heat in the mold, and accelerates the molding efficiency of the earphone shell. The condensed liquid after absorbing heat returns to the cooling box 9 and is accelerated to dissipate heat of the condensed liquid in the cooling box 9 under the action of the heat dissipation component 11, thereby accelerating the cooling effect of the mold, improving the efficiency of mold cooling and molding, and reducing the possibility of adhesion during demolding.

[0037] like Figure 1 and Figure 4As shown, when it is necessary to rotate the molding module 3 for demolding, the staff needs to disconnect the connection between the inlet pipe 5 and the input pipe 7. At this time, the staff recovers the condensate into the cooling box 9 by driving the pump 10, and then closes the control valve 34. Then the staff disconnects the magnetism of the electromagnet 14 through the control block. The electromagnet 14 moves toward the connecting block 19 under the elastic force of the reset spring 20. The movement of the electromagnet 14 drives the input pipe 7 to move in the connecting groove 16, so that the input pipe 7 is away from the inlet pipe 5, which is convenient for the staff to subsequently drive the molding module 3 to rotate for demolding.

[0038] like Figure 1 and Figure 3 As shown, the heat dissipation assembly 11 includes a motor 29 and a stirring rod 30. The motor 29 is fixedly mounted on the top wall of the cooling box 9. The stirring rod 30 is fixedly welded to the rotating shaft of the motor 29. The stirring rod 30 is inserted and rotated in the cooling box 9. The stirring rod 30 stirs the condensate. A plurality of heat dissipation holes 31 are provided on the top side wall of the cooling box 9. A cooling pipe 4 is arranged in an S shape on one side wall of the mold main chamber 1 close to the cooling box 9. One end of the cooling pipe 4 is connected to the output pipe 8, and the other end is connected to the cooling box 9. The condensate that absorbs heat in the cooling cavity is transported to the cooling box 9 through the cooling pipe 4. The S-shaped cooling pipe 4 can increase the contact area with the air and prolong the contact time with the air, thereby accelerating the heat dissipation in the condensate. The input pipe 7 is connected to the cooling box 9 through the connecting pipe 33, and the condensate cooled in the cooling box 9 is transported to the cooling cavity in the molding module 3. A double-sided fan 32 is installed on one side wall of the cooling box 9 close to the mold main chamber 1. The double-sided fan 32 is aimed at the cooling box 9 on one side and the cooling pipe 4 on the side wall of the mold main chamber 1 on the other side. The fan 32 can dissipate heat from the cooling pipe 4 on the side wall of the mold main chamber 1 to accelerate the air flow nearby, and dissipate heat inside the cooling box 9 to accelerate the flow of air inside the cooling box 9 and discharge the air with heat from the heat dissipation holes 31. When the condensate that absorbs heat in the molding module 3 enters the cooling box 9, the motor 29 starts to drive the stirring rod 30 to rotate, and the stirring rod 30 rotates the condensate to accelerate the heat dissipation effect of the condensate in the cooling box 9.

[0039] The implementation principle of the embodiment of the present application is as follows: when the staff is making the mold, the staff first fixes the molding module 3 to the molding support mold 2 through the fixing component 12, and then the staff connects the input pipe 7 and the inlet pipe 5, and the output pipe 8 and the outlet pipe 6 through two sets of connecting components 13, and then starts the driving pump 10. The condensate in the cooling box 9 circulates in the cooling pipe 4 driven by the driving pump 10, absorbs the heat of the mold, and accelerates the molding efficiency of the mold. The condensate after absorbing heat returns to the cooling box 9 and, under the action of the heat dissipation component 11, accelerates the heat dissipation efficiency of the condensate in the cooling box 9, thereby accelerating the cooling effect of the mold, improving the efficiency of mold cooling and molding, and reducing the possibility of adhesion during demolding.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
