Description

Technical Field

[0001] This utility model relates to the field of stamping die device technology, and in particular to a stamping die device for punching mobile phone cases. Background Technology

[0002] In the mass production of mobile phone cases, the stamping die device is the core equipment for achieving precise processing of holes (such as camera holes and charging port holes), but its processing efficiency and the ease of waste disposal have always been key issues restricting the production pace. In the prior art, such as the "a punching die device for punching mobile phone cases" disclosed in patent document CN222987135U, although the punching stability and basic material discharge function are optimized by setting guide rail components, detachable cutting tools and material discharge grooves, there are still obvious limitations: the device adopts a single-station design, and the base receiving groove can only hold a single mold. During processing, the mobile phone case to be processed must first be fixed to the mold. After the electric cylinder drives the punching cutter assembly to complete the punching, the machine must be stopped to remove the finished product and replace it with a new workpiece. The time for the punching component to wait for material to be loaded is relatively long, and only one workpiece can be processed at a time, which is difficult to meet the high-efficiency requirements of mass production of mobile phone cases, resulting in low production efficiency. At the same time, although the base has a material discharge groove and through hole for discharging waste, it does not have a dedicated guiding and positioning collection structure. After the waste is discharged through the material discharge groove, it is easy to scatter around the equipment, requiring manual cleaning periodically, which increases labor intensity. Therefore, we have introduced a new punching die device for punching mobile phone cases. Utility Model Content

[0003] The main objective of this invention is to provide a die-cutting device for mobile phone cases, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A punching die device for punching mobile phone cases includes a mounting platform. The mounting platform has an internal cavity with a placement and adjustment mechanism fixedly installed inside the cavity. An extension opening is provided at the rear right side of the mounting platform, and a collection device is provided inside the extension opening. An inspection door is movably installed at the front end of the mounting platform via a hinge. A support column is provided at the rear upper middle part of the mounting platform, and a support frame is provided at the upper end of the support column. A hydraulic cylinder is fixedly installed at the front upper end of the support frame, and a fixed seat is fixedly installed at the output end of the hydraulic cylinder. A punching cutter is detachably installed on the lower inner surface of the fixed seat.

[0005] Preferably, the placement and adjustment mechanism includes a motor, the output end of which is fixedly mounted with a drive gear via a rotating rod, the outer surface of which is meshed with a driven gear on the right side, a rotating column is fixedly mounted through the middle of the upper end of the driven gear, a turntable is fixedly mounted on the upper end of the rotating column, and six feeding ports are provided on the upper end of the turntable and the upper end of the mounting platform, with the positions of the six upper ports and the six lower ports corresponding one-to-one. Six punching dies are provided on the upper end of the turntable, and each of the six punching dies has a corresponding hole on its upper end.

[0006] Preferably, the six punching dies are arranged in an equidistant ring array, and the six corresponding holes correspond to the positions of the six discharge ports.

[0007] By adopting the above technical solution, the mold and the discharge port are aligned to avoid "waste jamming" caused by misalignment between the hole and the discharge port.

[0008] Preferably, the feed port and the corresponding hole are vertically aligned with the position of the punching tool.

[0009] By adopting the above technical solution, the cutting tool can directly cut along the guide of the corresponding hole when it descends, avoiding "hole misalignment" caused by tool deviation, and the waste generated by the cutting tool can fall directly down the vertical channel.

[0010] Preferably, the motor is fixedly installed on the lower inner wall of the inner cavity groove, and the lower outer surface of the rotating column is rotatably connected to the lower inner wall of the inner cavity groove through a bearing.

[0011] By adopting the above technical solution, the rotating column is connected to the lower wall through bearings, which greatly reduces rotational resistance, reduces wear between the column and the cavity wall, and extends the service life of the equipment.

[0012] Preferably, the collecting device includes a feeding box with an open right end. A collecting box is provided on the right side of the feeding box. Four casters are provided at the lower end of the collecting box. A push rod is provided at the right end of the collecting box. Limiting plates are provided at the upper front and upper rear ends of the collecting box.

[0013] By adopting the above technical solution: the feeding box receives the waste material generated by punching and guides it into the collection box through the opening at the right end. The universal wheels at the bottom of the collection box cooperate with the push rod on the right side to facilitate the operator to push the collection box to move.

[0014] Preferably, both limiting plates are fixedly connected to the right end of the mounting platform, the right side of the feeding box extends into the interior of the extension opening, and the lower inner wall of the feeding box is inclined with the left side higher than the right side.

[0015] By adopting the above technical solution, the limiting plate is fixed to the mounting platform instead of just connecting to the collection box, which can prevent the limiting plate from loosening as the collection box moves, and ensure the alignment accuracy of the collection box and the unloading box during long-term use.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the placement and adjustment mechanism, the six punching dies at the top of the turntable are arranged in an equidistant circular array. Together with the precise transmission system composed of a motor, drive gear, driven gear and rotating column, the dies can be switched to the punching station in an orderly manner. At the same time, it allows the operator to replace and replenish mobile phone cases at other stations while punching at the current station, without waiting for the processing of a single station to be completed, avoiding the material loading waiting time of traditional single-station equipment; thus improving production efficiency. 2. In the collection device, the inclined design of the lower wall of the feeding box, which is higher on the left and lower on the right, allows the waste to slide automatically to the opening by gravity, eliminating the need for manual cleaning of the waste inside the box. The cooperation between the feeding box and the extension port, as well as the positioning of the collection box by the limiting plate, ensures that the waste falls accurately into the collection box, avoiding scattering and pollution. At the same time, the universal wheels at the bottom of the collection box and the push rod at the right end allow operators to quickly transfer the waste without stopping the equipment, reducing the labor intensity of manual cleaning and handling, and realizing the automation and convenience of waste treatment.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A punching die device for punching mobile phone cases includes a mounting platform 1. The mounting platform 1 has an inner cavity 3. An adjustment mechanism 2 is fixedly installed inside the inner cavity 3. An extension port 4 is provided at the rear of the middle right end of the mounting platform 1. A collection device 5 is provided inside the extension port 4. An inspection door 6 is movably installed at the front end of the mounting platform 1 via a hinge. A support column 7 is provided at the rear of the middle upper end of the mounting platform 1. A support frame 8 is provided at the upper end of the support column 7. A hydraulic cylinder 9 is fixedly installed at the front upper end of the support frame 8. A fixed seat 10 is fixedly installed at the output end of the hydraulic cylinder 9. A punching cutter 11 is detachably installed on the lower inner surface of the fixed seat 10.

[0023] In this embodiment, the adjustment mechanism 2 includes a motor 21. The output end of the motor 21 is fixedly mounted with a drive gear 22 via a rotating rod. The outer right side of the drive gear 22 is meshed with a driven gear 23. A rotating column 24 is fixedly mounted through the middle of the upper end of the driven gear 23. A turntable 25 is fixedly mounted on the upper end of the rotating column 24. The upper end of the turntable 25 and the upper end of the mounting platform 1 are both provided with six feeding ports 26. The positions of the six upper feeding ports 26 and the six lower feeding ports 26 correspond one-to-one. The upper end of the turntable 25 is provided with six punching dies 27. The upper end of each of the six punching dies 27 is provided with a corresponding hole 28. The six punching dies 27 are arranged in an equally spaced ring array. The six corresponding holes 28 correspond to the positions of the six feeding ports 26 respectively. The feeding ports 26 and the corresponding holes 28 are vertically aligned with the positions of the punching cutter 11. The motor 21 is fixedly mounted on the lower inner wall of the inner cavity groove 3. The lower outer surface of the rotating column 24 is rotatably connected to the lower inner wall of the inner cavity groove 3 via a bearing.

[0024] With the above solution: During use, the operator can place multiple phone cases to be processed on six punching dies 27 arranged in a circular array at equal intervals on the upper end of the turntable 25, ensuring that the punching position of each phone case is precisely aligned with the corresponding hole 28 on the upper end of the corresponding punching die 27. This process does not require waiting for the punching action to be completed, and multi-station loading can be completed in advance, reducing the waiting time for subsequent processing from the source. Then, the motor 21 in the adjustment mechanism 2 is started. Since the motor 21 is fixedly installed on the lower inner wall of the inner cavity groove 3, it can ensure the stability of operation. Its output end drives the drive gear 22 to rotate through the rotating rod. The right side of the outer surface of the drive gear 22 meshes with the driven gear 23, thereby driving the rotating column 24, which is fixedly inserted in the middle of the upper end of the driven gear 23, to rotate. The lower part of the outer surface of the rotating column 24 is connected to the lower inner wall of the inner cavity groove 3 through the bearing. This design reduces rotational resistance and ensures rotational accuracy, allowing the turntable 25 at the top of the rotating column 24 to rotate smoothly. When one of the punching dies 27 on the turntable 25, which already has a phone case in it, rotates to a position directly below the punching cutter 11, the corresponding hole 28 on the punching die 27 aligns vertically with the punching cutter 11. At the same time, the feed port 26 at the top of the turntable 25 aligns one-to-one with the feed port 26 at the top of the mounting table 1, and the corresponding hole 28 also aligns vertically with the feed port 26. At this point, the punching cutter 11 immediately moves downward, passes through the phone case, and completes the punching process through the corresponding hole 28. While the punching cutter 11 is punching the phone case at the current workstation, the operator can replace or add phone cases to other punching dies 27 on the turntable 25 that are not in the punching position, without having to wait for the current punching to be completed before loading, further reducing waiting time.

[0025] In this embodiment, the collecting device 5 includes a feeding box 51 with an open right end. A collecting box 52 is provided on the right side of the feeding box 51. Four casters 54 are provided at the lower end of the collecting box 52. A push rod 53 is provided at the right end of the collecting box 52. Limiting plates 55 are provided at the upper front and upper rear ends of the collecting box 52. Both limiting plates 55 are fixedly connected to the right end of the mounting platform 1. The right side of the feeding box 51 extends into the interior of the extension opening 4. The lower inner wall of the feeding box 51 is inclined with the left side higher than the right side.

[0026] Through the above scheme: the waste generated by punching falls into the corresponding upper and lower feed ports 26 through the corresponding holes 28, and then enters the feed box 51 of the collection device 5. Because the lower wall of the feed box 51 is inclined from left to right, the waste slides quickly along the inclined surface to its right end opening under the action of gravity. The right side of the feed box 51 extends into the extension port 4. With the limit plate 55 fixedly connected to the upper front and upper rear of the collection box 52 and the right end of the mounting platform 1, it can be ensured that the collection box 52 is always aligned with the opening of the feed box 51. The waste can fall directly into the collection box 52 without manual cleaning, avoiding waiting time due to waste cleaning. When there is a lot of waste in the collection box 52, the operator can push the collection box 52 with four universal wheels 54 at the bottom through the push rod 53 at its right end to quickly transfer the waste. The transfer process does not affect the normal punching of the equipment, further reducing downtime.

[0027] It should be noted that this utility model is a punching die device for punching mobile phone cases. During use, the operator can first place multiple mobile phone cases to be processed on six punching dies 27 arranged in an equidistant circular array on the upper end of the turntable 25 in the placing and adjusting mechanism 2, ensuring that the position of each mobile phone case to be punched is precisely aligned with the corresponding hole 28 on the upper end of the corresponding punching die 27. Then, the motor 21 is started by the controller, and its output end drives the drive gear 22 to rotate through the rotating rod. The right side of the outer surface of the drive gear 22 meshes with the driven gear 23, thereby driving the rotating column 24, which is inserted and fixed in the middle of the upper end of the driven gear 23, to rotate. When one of the punching dies on the turntable 25 with a mobile phone case placed on it rotates, the device will rotate. When the punching die 27 rotates to a position directly below the punching tool 11, the corresponding holes 28 on the punching die 27 align vertically with the punching tool 11. Simultaneously, the feed port 26 at the top of the turntable 25 aligns one-to-one with the feed port 26 at the top of the mounting platform 1, and the corresponding holes 28 also align vertically with the feed ports 26. At this point, the hydraulic cylinder 9 on the support frame 8 supported by the support column 7 at the top of the mounting platform 1 is activated. The output end of the hydraulic cylinder 9 pushes the fixed base 10 and the punching tool 11, which is detachably mounted on the lower inner surface of the fixed base 10, downwards. The punching tool 11 passes through the phone case and completes the punching process through the corresponding holes 28. The detachable design of the punching tool 11 facilitates subsequent tool replacement according to the hole requirements of different phone cases. The machine is adaptable; while the punching tool 11 punches holes in the phone case at the current workstation, the operator can replace or replenish phone cases on other punching dies 27 on the turntable 25 that are not in punching positions, without waiting for the current punching to be completed before loading materials, further reducing the waiting time for workstation switching and realizing continuous processing; the waste generated by punching falls into the corresponding upper and lower feeding ports 26 through the corresponding holes 28, and then enters the feeding box 51 of the collection device 5 inside the extension port 4. Because the lower wall of the feeding box 51 is inclined from left to right, the waste slides quickly along the inclined surface to its right end opening under the action of gravity, without the need for manual cleaning of the feeding box 51, avoiding the accumulation of waste and affecting processing, and the right side of the feeding box 51 extends to the extension. Inside the opening 4, the limiting plates 55, which are fixedly connected to the upper front and upper rear of the collection box 52 and the right end of the mounting platform 1, ensure that the collection box 52 is always aligned with the opening of the discharge box 51. Waste materials can fall directly into the collection box 52, preventing waste materials from scattering and polluting the workshop environment. When there is a lot of waste material in the collection box 52, the operator can push the collection box 52, which is equipped with four universal wheels 54 at the bottom, through the push rod 53 at its right end to quickly transfer the waste material. There is no need to stop the machine during the transfer process, which does not affect the normal punching of the equipment and reduces downtime. In addition, the maintenance door 6, which is installed at the front of the mounting platform 1 through a hinge, facilitates the subsequent maintenance of the adjustment mechanism 2 placed in the inner cavity groove 3, reducing the difficulty and cost of equipment maintenance.After the punching at the current workstation is completed, motor 21 continues to drive turntable 25 to rotate, moving the next punching die 27 with a pre-placed phone case below the punching cutter 11. This process is repeated to achieve batch punching of phone cases, significantly reducing waiting time at each stage and improving production efficiency.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
