Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumper processing, in particular to an automobile bumper processing die. Background Art

[0002] The automotive bumper processing mold is a tool used to manufacture automotive bumpers. It mainly consists of two parts: an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press to produce the automotive bumper.

[0003] The installation and disassembly process of the mold may involve complex mechanical structures and a large number of bolt tightening operations, which not only requires a lot of manpower and time, but is also prone to problems such as inaccurate installation and mold damage, affecting production efficiency and product quality. During the unloading process, problems such as unloading problems are prone to occur, affecting production continuity and product quality, and adding additional processing costs and time.

[0004] Therefore, we propose a car bumper processing mold. Utility Model Content

[0005] The main purpose of the present utility model is to provide a car bumper processing mold, in order to prevent the mold installation and disassembly from being complicated and time-consuming, and causing problems such as inaccurate installation and mold damage, as well as problems such as unsmooth unloading, residue or damage, thereby improving production efficiency, product quality, and production fluency and stability, reducing costs, and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A mold for processing an automobile bumper comprises a support base, wherein brackets are fixedly connected at the edges of both ends of the top of the support base, an electric cylinder is fixedly connected to the middle of the top of the bracket, the bottom output end of the electric cylinder passes through the bracket and is fixedly connected to a movable plate, and both ends of the movable plate are fixedly connected to first sliders arranged opposite to each other, and first sliding grooves for slidably connecting the first sliders are provided inside the two ends of the bracket;

[0008] The support base is provided with a first cavity on both sides, a fixing mechanism is provided inside the first cavity, an upper mold is clamped in the support base through the fixing mechanism, and a driving motor is provided on the outside of the two sides of the support base at positions corresponding to the fixing mechanism, and the fixing mechanism includes a sliding support plate, the middle of one side of the support plate is rotatably connected to a screw rod, and the outer side of the screw rod is rotatably connected to the support plate, and the support plate is provided with multiple groups of second magnets on the side close to the support plate, and a first magnet corresponding to the second magnet is provided inside one side of the support plate, and the first magnet and the second magnet repel each other with the same polarity, and multiple springs are provided between the support plate and the inner wall of one side of the movable plate, and multiple groups of connecting rods are provided on the side of the support plate away from the spring, and one end of the connecting rod is fixedly connected to the limiting plate;

[0009] A lower mold is provided on the top of the support base, a slide rail is fixedly connected to the middle position of the outer wall of the bottom end of the lower mold, and a vibration motor is slidably connected to the bottom of the slide rail.

[0010] By adopting the above technical solution, the electric cylinder is started, and the output end of the electric cylinder pushes the movable plate downward. The first sliders at both ends of the movable plate slide along the first slide grooves inside the two ends of the bracket, ensuring that the movable plate can move smoothly in the vertical direction. The entire process is powered by the electric cylinder, and the cooperation between the first slider and the first slide groove ensures the accuracy and stability of the movement.

[0011] When the upper mold needs to be fixed, the drive motor is started, and the drive motor drives the screw to rotate, thereby pushing the push plate to slide in the first cavity. During the sliding process of the push plate, due to the repulsive force generated by the first magnet and the second magnet of the same polarity, and the elastic effect of the spring, the push plate can move inward more stably and be clamped and fixed with the upper mold through the connecting rod and the limit plate. When the upper mold needs to be removed, the drive motor is operated in the reverse direction to move the push plate in the reverse direction and release the clamping connection with the upper mold;

[0012] When the lower mold is unloading, the vibration motor can slide along the slide rail. When the vibration motor is running, it generates vibration, which can be transmitted to the lower mold through the slide rail, thereby playing an auxiliary role in the unloading process.

[0013] Furthermore, the top and bottom ends of the abutment plate are fixedly connected to a second slider, and the top and bottom ends of the first cavity are also provided with a second sliding groove for sliding connection to the second slider.

[0014] By adopting the above technical solution, during the movement of the support plate, the second sliders at the top and bottom ends of the support plate slide along the second slide grooves at the top and bottom ends of the first cavity. This design makes the movement of the support plate more stable and smooth, and can ensure that it can accurately perform telescopic movements in the horizontal direction, thereby better realizing the fixing and loosening operations with the upper mold, and ensuring the stability and reliability of the entire mold device during the mold fixing and related operations.

[0015] Furthermore, a handle is connected to one side of the bottom of the vibration motor via bolts.

[0016] By adopting the above technical solution, the vibration motor can be conveniently operated manually through the handle connected by bolts. When the position of the vibration motor needs to be adjusted or other operations need to be performed, the handle can be held to move or control the vibration motor so that it slides along the slide rail to the desired position.

[0017] Furthermore, the driving motors are provided with four groups, and the output end of one end of the driving motor passes through the movable plate and is fixedly connected to the screw rod.

[0018] By adopting the above technical solution, four sets of drive motors provide power. When the drive motors are working, their output ends drive the screw to rotate. Since the screw is connected to the back plate, the rotation of the screw will be converted into linear motion of the back plate. Through the synchronous operation of the four sets of drive motors, the movement of the back plate in the first cavity can be controlled more accurately and stably, thereby achieving a firm fixation or release operation of the upper mold, ensuring the reliability and safety of the mold during operation; at the same time, the design of the output end running through the movable plate makes the entire structural layout more compact and the transmission more direct and efficient.

[0019] Furthermore, a second cavity is provided inside the support base, and the slide rail, the vibration motor and the handle are all located inside the second cavity.

[0020] By adopting the above technical solution, the second cavity is provided to provide accommodation space for the slide rail, the vibration motor and the handle. At the same time, the second cavity plays a certain protective role for them, preventing them from being interfered with or damaged by external factors.

[0021] Furthermore, a door panel is rotatably connected to a lower portion of one side of the support base at a position located in the second cavity, and a handle is welded to one side of the door panel.

[0022] By adopting the above technical solution, when it is necessary to inspect, maintain or adjust components such as the vibration motor inside the second cavity, the door panel can be easily opened by pulling the handle, so that the relevant components in the second cavity can be directly operated. After completing the corresponding work, the door panel can be closed by rotating it, thereby protecting and sealing the internal components of the second cavity.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (3) The utility model provides a mold for processing automobile bumpers, which uses a driving motor to drive a screw rod to slide the abutment plate. With the help of the repulsion between the first magnet and the second magnet and the action of the spring, the upper mold can be stably clamped, fixed and disassembled, and the operation is convenient.

[0025] (4) The utility model provides a mold for processing automobile bumpers. When the lower mold is unloading, the vibration motor can slide along the slide rail and generate vibration, and the vibration is transmitted through the slide rail to assist unloading, thereby improving unloading efficiency and smoothness.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] In order to prevent the mold installation and disassembly from being complicated and time-consuming, causing problems such as inaccurate installation and mold damage, as well as problems such as unloading being not smooth, residue or damage, so as to improve production efficiency, product quality, smoothness and stability of production, and reduce costs, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a mold for processing an automobile bumper includes a support base 1, with brackets 2 fixedly connected to the edges of the top and two ends of the support base 1, an electric cylinder 3 fixedly connected to the middle of the top of the bracket 2, and the bottom output end of the electric cylinder 3 passes through the bracket 2 and is fixedly connected to a movable plate 4, and both ends of the movable plate 4 are fixedly connected to first sliders 5 arranged opposite to each other, and first sliding grooves 6 for slidingly connecting the first slider 5 are provided inside the two ends of the bracket 2;

[0033] A first cavity 10 is provided inside both sides of the support base 1, and a fixing mechanism 7 is provided inside the first cavity 10. An upper mold 8 is clamped in the support base 1 through the fixing mechanism 7. A driving motor 9 is provided on the outside of both sides of the support base 1 at positions corresponding to the fixing mechanism 7. The fixing mechanism 7 includes a sliding support plate 11, a screw rod 13 is rotatably connected to the middle part of one side of the support plate 11, and a support plate 14 is rotatably connected to the outer side of the screw rod 13. A plurality of groups of second magnets 15 are provided on the side of the support plate 14 close to the support plate 11, and a first magnet 12 corresponding to the second magnet 15 is provided on one side of the support plate 11, and the first magnet 12 and the second magnet 15 repel each other with the same polarity. A plurality of springs 18 are provided between the inner wall of the support plate 11 and one side of the movable plate 4, and a plurality of connecting rods 19 are provided on the side of the support plate 11 away from the spring 18, and one end of the connecting rod 19 is fixedly connected to the limiting plate 20;

[0034] A lower mold 22 is provided at the top of the support base 1 , a slide rail 23 is fixedly connected to the middle position of the outer wall of the bottom end of the lower mold 22 , and a vibration motor 24 is slidably connected to the bottom of the slide rail 23 .

[0035] When in use, the electric cylinder 3 is started, and the output end of the electric cylinder 3 pushes the movable plate 4 to move downward. The first sliders 5 at both ends of the movable plate 4 slide along the first slide grooves 6 inside the two ends of the bracket 2, ensuring that the movable plate 4 can move smoothly in the vertical direction. The entire process is powered by the electric cylinder 3, and the cooperation between the first sliders 5 and the first slide grooves 6 ensures the accuracy and stability of the movement.

[0036] When it is necessary to fix the upper mold 8, the drive motor 9 is started, and the drive motor 9 drives the screw 13 to rotate, thereby pushing the push plate 11 to slide in the first cavity 10. During the sliding process of the push plate 11, due to the repulsive force generated by the first magnet 12 and the second magnet 15, and the elastic effect of the spring 18, the push plate 11 can move inward more stably and be fixed to the upper mold 8 through the connecting rod 19 and the limit plate 20. When it is necessary to remove the upper mold 8, the drive motor 9 is operated in the reverse direction to move the push plate 11 in the reverse direction to release the clamping connection with the upper mold 8;

[0037] When the lower mold 22 is unloading, the vibration motor 24 can slide along the slide rail 23. The vibration motor 24 generates vibration when running, and this vibration can be transmitted to the lower mold 22 through the slide rail 23, thereby playing an auxiliary role in the unloading process.

[0038] For example, Figure 2 、 Figure 3 As shown, the present invention further includes that the top and bottom ends of the abutment plate 11 are fixedly connected to a second slider 16 , and the top and bottom ends of the first cavity 10 are also provided with a second sliding groove 17 for slidingly connecting the second slider 16 .

[0039] During use, during the movement of the support plate 11, the second sliders 16 at the top and bottom ends of the support plate 11 slide along the second slide grooves 17 at the top and bottom ends of the first cavity 10. This design makes the movement of the support plate 11 more stable and smooth, and can ensure that it can accurately perform telescopic movements in the horizontal direction, thereby better realizing the fixing and loosening operations with the upper mold 8, and ensuring the stability and reliability of the entire mold device during the mold fixing and related operations.

[0040] For example, Figure 4 As shown, the present invention further includes a handle 25 connected to one side of the bottom of the vibration motor 24 via bolts.

[0041] During use, the vibration motor 24 can be conveniently manually operated through the handle 25 connected by bolts. When the position of the vibration motor 24 needs to be adjusted or other operations need to be performed, the handle 25 can be held to move or control the vibration motor 24 so that it slides along the slide rail 23 to the desired position.

[0042] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the utility model also includes that the driving motor 9 is provided with four groups, and the output end of one end of the driving motor 9 passes through the movable plate 4 and is fixedly connected to the screw rod 13.

[0043] During use, four groups of drive motors 9 provide power. When the drive motors 9 are working, their output ends drive the screw rod 13 to rotate. Since the screw rod 13 is connected to the abutment plate 11, the rotation of the screw rod 13 will be converted into a linear motion of the abutment plate 11. Through the synchronous operation of the four groups of drive motors 9, the movement of the abutment plate 11 in the first cavity 10 can be controlled more accurately and stably, thereby achieving a firm fixation or release operation of the upper mold 8, ensuring the reliability and safety of the mold during operation; at the same time, the design of the output end running through the movable plate 4 makes the entire structural layout more compact and the transmission more direct and efficient.

[0044] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes that a second cavity 21 is provided inside the support base 1 , and the slide rail 23 , the vibration motor 24 and the handle 25 are all located inside the second cavity 21 .

[0045] When in use, the second cavity 21 provides a space for accommodating the slide rail 23, the vibration motor 24 and the handle 25. At the same time, the second cavity 21 protects them to a certain extent, preventing them from being interfered with or damaged by external factors.

[0046] For example, Figure 1 As shown, the present invention further includes that a door panel 28 is rotatably connected to the lower portion of one side of the support base 1 at the position of the second cavity 21 , and a handle 29 is welded to one side of the door panel 28 .

[0047] During use, when it is necessary to inspect, maintain or adjust components such as the vibration motor 24 inside the second cavity 21, the door panel 28 can be easily opened through the handle 29, so that the relevant components inside the second cavity 21 can be directly operated. After completing the corresponding work, the door panel 28 can be closed by rotating it, thereby protecting and sealing the internal components of the second cavity 21.

[0048] It should be noted that the present invention is a mold for processing automobile bumpers. The edges of both ends of the top of the support base 1 are fixedly connected to the bracket 2. An electric cylinder 3 is installed in the middle of the top of the bracket 2. The output end of the electric cylinder passes through the bracket 2 and is connected to the movable plate 4. The movable plate 4 cooperates with the first slide groove 6 on the bracket 2 through the first slider 5 to achieve smooth vertical movement.

[0049] The support base 1 has first cavities 10 on both sides, within which a fixing mechanism 7 is used to engage the upper mold 8. The fixing mechanism 7 includes a stop plate 11, a screw 13, a support plate 14, a first magnet 12, a second magnet 15, a spring 18, a connecting rod 19, and a limit plate 20. The drive motor 9 drives the screw 13 to rotate and push the stop plate 11 to move, thereby securing and releasing the upper mold 8.

[0050] A lower mold 22 is provided at the top of the support base 1, and a slide rail 23 and a vibration motor 24 are provided at the bottom of the lower mold 22 to assist in blanking;

[0051] The second slider 16 and the corresponding second slide groove 17 on the support plate 11 ensure that the support plate 11 moves smoothly. The four sets of drive motors 9 can accurately control the movement of the support plate 11. The second cavity 21 in the support base 1 is used to accommodate the slide rail 23, the vibration motor 24, etc., and has a corresponding door panel 28 for easy inspection and maintenance.
