[0002] An acoustic package refers to a combination of a series of materials, components or systems used to control, optimize or isolate sound, mainly applied to reduce noise, improve sound quality or achieve specific acoustic effects. Its housing texture is usually made of metal, and generally uses a stamping process for production.

[0003] Since some holes for installation and wire routing are required on the surface of the acoustic package housing, it is necessary to punch holes at the corresponding positions of the product during production; for the existing acoustic package housing, after stamping, the formed product is usually placed in the next station for punching. Before punching, operations such as limiting and fixing the acoustic package housing are also required, and the operation is relatively complex, which will greatly reduce the production efficiency of the acoustic package housing; while some equipment sets punching tools in the mold, although punching can be completed simultaneously during stamping, since the stamped product will be closely attached to the mold, a slightly raised burr will be generated at the hole position after punching, and the raised part will combine with the punching part on the mold, which is not convenient for subsequent demolding.

Specific implementation manner

[0034] Please refer to Figures 1-12 , the present invention provides a technical solution: an integrated stamping and trimming device for acoustic package housing processing, including a base plate 1, on which a first mold 2 and at least two second molds 3 are provided, and the first mold 2 is fixedly connected to the base plate 1; a driving mechanism for driving the second mold 3 to be combined with the first mold 2 is provided on the base plate 1;

[0035] An punching mechanism is provided inside the second mold 3, and the punching mechanism is used for punching a plurality of holes on the surface of the acoustical package housing formed by stamping when the second mold 3 and the first mold 2 are combined;

[0036] The first mold 2 is internally provided with a demolding mechanism, which is used to separate the part of the second mold 3 at the punching position from the acoustic package housing after the second mold 3 completes stamping and punching of the acoustic package housing;

[0037] The demolding mechanism includes a plurality of sliding cavities 4 opened on the side wall of the second mold 3, and the position of each sliding cavity 4 corresponds to the position of the side punching of the acoustic package housing; a support block 5 is slidably connected in the sliding cavity 4, and punching cavities 6 are opened on the side wall of the support block 5 and the bottom of the second mold 3; a locking component is arranged in the sliding cavity 4, and the locking component is used to fix the support block 5 at a position where its inner side surface is flush with the side wall of the second mold 3; an unlocking component is arranged in the sliding cavity 4, and the unlocking component is used to unlock the support block 5 and drive the support block 5 to slide towards the inside of the sliding cavity 4 when the second mold 3 and the first mold 2 are closed;

[0038] A trimming mechanism is arranged on the bottom plate 1, and the trimming mechanism is used to trim the burrs at the punching positions on the surface of the acoustic package housing to be neat and flat after the acoustic package housing is demolded from the first mold 2;

[0039] During operation, the raw material to be stamped is placed on the first mold 2, and then the driving mechanism is started. The driving mechanism drives a second mold 3 to move downward to be closed with the first mold 2. After the closing is completed, the acoustic package housing is stamped and formed. At this time, the punching mechanism can be started, and through the punching mechanism, a plurality of holes can be punched at specific positions on the stamped and formed acoustic package housing;

[0040] Since the part of the acoustic package housing at the hole position bulges outwards during punching, when demolding, the bulging part at the hole of the acoustic package housing will get stuck in the first mold 2, which is not convenient for demolding; at this time, the unlocking component is started, and the unlocking component unlocks the part of the first mold 2 that fits with the hole of the acoustic package housing and drives this part to separate from the acoustic package housing. At this time, the formed and punched acoustic package housing can be smoothly separated from the first mold 2, so that the integration of stamping and punching can be realized, and the production efficiency of the acoustic package housing can be improved;

[0041] The separated acoustic package housing is placed at the trimming position, and by starting the trimming mechanism, the burrs at the bulging part of the punching of the acoustic package housing can be trimmed to be neat and flat.

[0042] As a further solution of the present invention, the punching mechanism includes a pressing plate 7 slidably arranged vertically in the second mold 3. A plurality of cylinder ones 8 are fixedly connected to the pressing plate 7, and the telescopic ends of the cylinder ones 8 are fixedly connected to the second mold 3; a plurality of pressing rods one 9 and a pressing rod two 10 are fixedly connected to the bottom of the pressing plate 7; a plurality of punching heads 11 are slidably connected to the side wall and the bottom position of the stamping part of the second mold 3. A connecting rod 12 is rotatably connected to the inner end of the punching head 11 at the side wall position of the second mold 3, and the upper part of the connecting rod 12 is rotatably connected to the pressing rod one 9; the upper end of the punching head 11 at the bottom position of the second mold 3 is fixedly connected to the pressing rod two 10;

[0043] On the side wall of the second mold 3, the upper ends of two connecting rods 12 connected to two punches 11 arranged vertically up and down in the same vertical direction are both connected to the same first pressure rod 9;

[0044] During operation, refer to Figures 4-6 , when the second mold 3 and the first mold 2 are closed, the acoustic package housing is initially stamped and formed. At this time, a plurality of first cylinders 8 in the second mold 3 are started, and the first cylinders 8 drive the pressing plate 7 to move downward relative to the second mold 3. The pressing plate 7 will drive a plurality of first pressure rods 9 and a second pressure rod 10 to move downward; when the second pressure rod 10 moves downward, it will drive a plurality of punches 11 at the bottom of the second mold 3 to move downward. When the bottom punches 11 move downward, corresponding holes will be punched in the bottom side part of the acoustic package housing; when the first pressure rod 9 moves downward, the corresponding punches 11 will be driven to move outward through the connecting rods 12 connected to it. When the punches 11 move, holes can be punched at the corresponding positions on the side of the acoustic package housing; after punching is completed, the first cylinders 8 are started to drive the pressing plate 7 to reset, and the pressing plate 7 can drive all the punches 11 to reset through a plurality of first pressure rods 9 and a second pressure rod 10.

[0045] As a further solution of the present invention, the locking assembly includes blocks 14 respectively arranged at four corner positions in the sliding cavity 4. The blocks 14 are slidably connected to the inner wall of the sliding cavity 4 and are in snap-fit connection with the support block 5; a lead screw 15 is provided on the block 14 and is threadedly connected thereto. The lead screw 15 does not have self-locking property and is rotatably connected to the inner wall of the sliding cavity 4;

[0046] During operation, refer to Figures 7-8 , since when the acoustic package housing is stamped and formed, the stamping material needs to be fully supported by the inner wall of the first mold 2 and the outer surface of the second mold 3, the four blocks 14 can strongly support the support block 5 in the sliding cavity 4, so that the support block 5 can maintain sufficient extrusion pressure on the material during material stamping.

[0047] As a further solution of the present invention, the unlocking assembly includes chutes 16 opened at both sides of the sliding cavity 4 and penetrating the upper surface of the first mold 2. A rack 17 is slidably connected in the chutes 16. Gears 18 are meshed with both the upper and lower sides of the surface of the rack 17. The upper and lower gears 18 are respectively fixedly connected to the lead screws 15 at the upper and lower positions; a first spring 19 is fixedly connected to the rack 17. The bottom end of the first spring 19 is fixedly connected to the inner wall of the chute 16; springs 20 are fixedly connected to the four corner positions of the support block 5. The other ends of the springs 20 are fixedly connected to the inner wall of the sliding cavity 4; a pressing unit is provided inside the second mold 3, and the pressing unit is used to press all the racks 17 in the first mold 2 downward when the second mold 3 and the first mold 2 are closed; a reset unit is provided at the bottom of the second mold 3, and the reset unit is used to drive the support block 5 in the sliding cavity 4 to reset after the second mold 3 and the first mold 2 are separated;

[0048] Refer to when working Figure 4 and Figures 7-8 . When punching, in order to prevent the deformation of the acoustic package housing, the support plate supports the acoustic package housing at the punching position of the acoustic package housing, which can ensure that the acoustic package housing completes punching well. However, after punching the acoustic package housing, slight deformation will still occur at the punching position, that is, slight burrs protruding outward will be generated at the punching part, and the protruding part will get stuck in the punching cavity 6. At this time, all the racks 17 are pressed downward by the pressing mechanism. When the racks 17 move downward, they drive the two gears meshed with them to rotate, and the gears drive the screw rod 15 to rotate. When the screw rod 15 rotates, it will drive the block 14 sleeved on its surface to move and disengage from the support block 5. When all the blocks 14 in the sliding cavity 4 are disengaged from the support block 5, under the action of the second spring 20, the support block 5 moves inward into the sliding cavity 4 and disengages from the acoustic package housing. At this time, the acoustic package housing can be smoothly separated from the first mold 2 (the contraction amount of the punch 11 can be controlled by a plurality of first cylinders 8, and the punch 11 can be controlled inside the punching of the acoustic package housing, and then the acoustic package housing is driven to move upward by moving the second mold 3 upward to disengage from the first mold 2).

[0049] As a further solution of the present invention, the pressing unit includes pressing rods three 21 equal in number to the racks 17, and each pressing rod three 21 is located directly above a rack 17; the pressing rods three 21 are slidably connected to the second mold 3 and the whole pressing rods three 21 are located inside the second mold 3, and the upper ends of the pressing rods three 21 are fixedly connected to the pressing plate 7;

[0050] Refer to when working Figure 4 . When the second mold 3 and the first mold 2 are closed, several first cylinders 8 are started to drive the pressing plate 7 to move downward. The pressing plate 7 will drive the pressing rod one 9, a plurality of pressing rods two 10 and a plurality of pressing rods three 21 connected to it to move downward; while the pressing rod one 9 and a plurality of pressing rods two 10 drive a plurality of punches 11 to complete punching, a plurality of pressing rods three 21 just extend out and fit with a plurality of racks 17 at this time. As the pressing plate 7 continues to move downward, the pressing rods three 21 will start to press the racks 17 in contact with them downward.

[0051] As a further solution of the present invention, the reset unit includes a frame body 22 slidably arranged vertically on the bottom plate 1. The frame body 22 is fixedly connected with several inclined rods 23 at the bottom position of the first mold 2. The number of the inclined rods 23 is equal to the number of the sliding cavities 4; through holes 24 communicating with the sliding cavities 4 are opened above each inclined rod 23 at the bottom of the first mold 2, and the inclined rods 23 are in clearance fit with the through holes 24; the upper part of the frame body 22 is located above the second mold 3;

[0052] Refer to when working Figures 7-8 and Figure 10, after the acoustic package housing is punched, the rack 17 moves downward to drive the block 14 to disengage from the support plate. At this time, under the action of the second spring 20, the support plate moves into the sliding cavity 4; at this time, the second mold 3 can be driven to move upward. When the second mold 3 moves upward, it can drive the acoustic package housing to move upward and separate from the first mold 2; when the acoustic package housing is completely separated from the first mold 2, at this time, the second mold 3 just fits against the upper part of the frame 22 and drives the frame 22 to move upward. The frame 22 will drive a plurality of inclined rods 23 at the bottom to move upward. The inclined rods 23 pass through the through holes 24 and start to move into the sliding cavity 4. The inclined surface of the inclined rod 23 fits against the support plate in the sliding cavity 4; since the second mold 3 drives the frame 22 to continue to move upward, under the extrusion of the inclined surface of the inclined rod 23, the support plate will start to gradually reset; since the lead screw 15 does not have self-locking property, when the third pressure rod 21 disengages from the rack 17, the rack 17 has a driving force to automatically reset upward under the action of the first spring 19, and at the same time, the block 14 also has a tendency to automatically reset; when the support plate is completely reset, the support plate no longer blocks the block 14. The block 14 and the rack 17 are reset under the action of the first spring 19, and the block 14 again maintains the state of clamping the support block 5.

[0053] As a further solution of the present invention, the trimming mechanism includes a plurality of driving plates 25 installed on the bottom plate 1. The driving plates 25 and the bottom plate 1 are both provided with telescopic shafts 26. A grinding disc 27 is fixedly connected to the telescopic shaft 26; each grinding disc 27 corresponds to the punching position of the acoustic package housing; the telescopic shaft 26 is an elastic telescopic shaft 26 and the edge part of the grinding surface of the grinding disc 27 is in an arc chamfer shape;

[0054] During operation, refer to Figure 10 , when the formed acoustic package housing follows the second mold 3 to separate from the first mold, at this time, the second mold 3 is driven to drive the acoustic package housing to move to a position above a plurality of grinding discs 27, and then the acoustic package housing is driven to move downward; when the acoustic package housing moves downward, the grinding disc 27 will fit on the surface of the acoustic package housing. Since the edge of the grinding disc 27 is in an arc chamfer shape, when the convex part at the punching position of the acoustic package housing moves to the position where it fits against the grinding disc 27, it will appropriately squeeze the grinding disc 27 to move outward along the edge of the grinding disc 27; when the acoustic package housing moves downward to the position where it fits against the bottom grinding disc 27, at this time, all the grinding discs 27 are in contact with the punching parts on the acoustic package housing. Then, the driving plate 25 controlled by the program drives the grinding disc 27 to rotate, and the burrs protruding from the punching parts on the acoustic package housing can be ground and trimmed flat.

[0055] As a further solution of the present invention, the driving mechanism includes a second cylinder 28 fixedly connected to the bottom plate 1. A second gear 29 is fixedly connected to the telescopic end of the second cylinder 28. A connecting plate 30 is rotatably connected to the upper end of the second gear 29. The connecting plate 30 is fixedly connected to the two second molds 3, and a motor 31 is fixedly connected to the connecting plate 30. A third gear 32 is fixedly connected to the bottom end of the output shaft of the motor 31. The third gear 32 meshes with the second gear 29;

[0056] During operation, refer to Figures 2-3 , by starting the second cylinder 28, the connecting plate 30 can be driven to move up and down, and the connecting plate 30 can drive the two second molds 3 connected thereto to move up and down to complete the stamping work; when the acoustic package housing is stamped, start the motor 31 to drive the third gear 32 to rotate. Under the action of the second gear 29, the third gear 32 can drive the connecting plate 30 to rotate, and the connecting plate 30 will swap the positions of the two second molds 3.
