Description

Technical Field

[0001] This utility model belongs to the field of mold design technology, and in particular relates to a mold for manufacturing automotive sealing strips. Background Technology

[0002] Automotive sealing strip manufacturing molds are tools and equipment specifically used to produce automotive sealing strips. Sealing strips are key components in automobiles used to prevent water, air, dust, and noise from entering the vehicle interior. They are typically installed in locations such as car doors, windows, and roofs. To ensure the quality and functionality of these sealing strips, they must be manufactured using precision molds.

[0003] When automotive sealing strips are removed from the mold, they still need to undergo a series of processing steps, which is quite cumbersome. If the sealing strips can be polished at the same time as they are removed, the burrs or irregular edges on the surface of the sealing strips can be removed, which will facilitate the subsequent processing of the sealing strips. Therefore, we have proposed an automotive sealing strip manufacturing mold. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for manufacturing automotive sealing strips. The sealing strip is pushed by a pusher plate that can slide inside the connecting plate, and then a grinding wheel grinds the sealing strip. After grinding, a cleaning wheel cleans the surface of the sealing strip, thus solving the problem of grinding the sealing strip when it is pushed out of the mold.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a mold for manufacturing automotive sealing strips, including a support frame, a connecting plate fixedly connected to the top of the support frame, a grinding mechanism provided on the outer surface of the support frame, and a fixing mechanism provided on the top of the connecting plate;

[0007] The grinding mechanism includes a motor frame one, with a first motor fixedly connected to the inner wall of the motor frame one. The output shaft of the first motor is fixedly connected to a rotating shaft via a coupling. A gear is fixedly connected to the outer surface of the rotating shaft, and a rack meshes with the outer surface of the gear. A push plate is fixedly connected to the top of the rack, and a connecting strip is fixedly connected to the top of the connecting plate. A motor frame two is fixedly connected to the top of the connecting strip, and a second motor is fixedly connected to the inner wall of the motor frame two. A grinding wheel is fixedly connected to the output shaft of the second motor via a coupling. A pulley one is fixedly connected to the outer surface of the grinding wheel, and a belt is driven to the outer surface of the pulley one. By using a grinding wheel that can rotate within the connecting strip, the sealing strip can be ground when it is pushed out of the connecting strip, making the edge of the sealing strip more rounded and smooth, thereby reducing problems in subsequent processing.

[0008] Furthermore, the end of the belt away from the first pulley is connected to the second pulley, the inner wall of the connecting strip is rotatably connected to the cleaning wheel, the outer surface of the motor frame is fixedly connected to the outer surface of the support frame, and the outer surface of the rack is slidably connected to the outer surface of the connecting plate.

[0009] Furthermore, the outer surface of the push plate is slidably connected to the inner wall of the connecting plate, there are two connecting strips, there are two grinding wheels, the outer surface of the grinding wheel is rotatably connected to the inner wall of the connecting strip, the inner wall of the second pulley is fixedly connected to the outer surface of the grinding wheel, and there are two cleaning wheels.

[0010] Furthermore, the fixing mechanism includes a connecting ring fixedly connected to the top of the connecting plate, and a plurality of connecting rings are provided, with a fixing rod fixedly connected to the top of the connecting ring.

[0011] Furthermore, a spring is fixedly connected to the top of the connecting ring, the inner side of the spring is sleeved with the outer surface of the fixing rod, and a pressure plate is fixedly connected to the end of the spring away from the connecting ring, and the inner wall of the pressure plate is slidably connected to the outer surface of the fixing rod.

[0012] Furthermore, a mold is slidably connected to the bottom of the pressure plate, the bottom of the mold is slidably connected to the top of the connecting plate, and a clamping block is slidably connected to the bottom of the pressure plate. There are two clamping blocks in total, and the outer surface of the clamping block is in contact with the outer surface of the mold.

[0013] Furthermore, a connecting block is fixedly connected to the top of the clamping block, the outer surface of the connecting block is slidably connected to the inner wall of the pressure plate, a moving plate is rotatably connected to the inner wall of the connecting block, and a threaded cylinder is rotatably connected to the end of the moving plate away from the connecting block. By using the clamping block that can clamp the mold, the mold can be fixed when the sealing strip is pushed out, which can ensure that the forming process of the sealing strip is more stable and accurate, and avoid the effect of slight displacement or deviation of the mold, which would lead to inaccurate dimensions of the sealing strip.

[0014] Furthermore, a threaded rod is threadedly connected to the inner wall of the threaded cylinder, and an L-shaped block is fixedly connected to the top of the pressure plate. A bolt is threadedly connected to the inner wall of the L-shaped block, and the outer surface of the bolt contacts the outer surface of the threaded rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a grinding wheel. A second motor causes the grinding wheel to rotate within the connecting strip. The grinding wheel then drives pulley one to rotate, which in turn drives pulley two to rotate via a belt. This pulley two then drives the grinding wheel on the other side to rotate. The sealing strip first passes through the grinding wheel. By utilizing the grinding wheel, which can rotate within the connecting strip, the sealing strip is ground as it is pushed out of the connecting strip. This results in a smoother and more rounded edge to the sealing strip, reducing the likelihood of problems during subsequent processing.

[0017] 2. This utility model incorporates a clamping block that rotates the threaded rod. This rotation causes the threaded cylinder to move upwards, which in turn moves the moving plate upwards. The moving plate then pulls the connecting block, causing the connecting blocks to move closer together. This allows the connecting block to move the clamping block and clamp the mold. By using the clamping block to clamp the mold, the mold can be fixed when the sealing strip is pushed out, ensuring a more stable and precise forming process for the sealing strip. This prevents minor displacement or deviation of the mold, which could lead to inaccurate dimensions of the sealing strip.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a mold for manufacturing automotive sealing strips, including a support frame 101, a connecting plate 102 fixedly connected to the top of the support frame 101, a grinding mechanism 2 provided on the outer surface of the support frame 101, and a fixing mechanism 3 provided on the top of the connecting plate 102.

[0030] The grinding mechanism 2 includes a motor frame 201. This device first pushes the sealing strip out of the fixing mechanism 3, and then, at the same time, grinds the sealing strip through the grinding mechanism 2 to facilitate subsequent processing of the sealing strip. A first motor 202 is fixedly connected to the inner wall of the motor frame 201. The output shaft of the first motor 202 is fixedly connected to a rotating shaft 203 through a coupling. A gear 204 is fixedly connected to the outer surface of the rotating shaft 203, and a rack 205 meshes with the outer surface of the gear 204. The motor frame 201 fixes the position of the first motor 202 to prevent the first motor 202 from rotating during operation. Then, the first motor 202 causes the rotating shaft 203 to rotate, and then the rotating shaft 203 drives the gear 204. The rotation of gear 204 causes rack 205 to move. A push plate 206 is fixedly connected to the top of rack 205, and a connecting strip 207 is fixedly connected to the top of connecting plate 102. A motor frame 208 is fixedly connected to the top of connecting strip 207, and a second motor 209 is fixedly connected to the inner wall of motor frame 208. Rack 205 drives push plate 206 to move together, causing push plate 206 to push out the sealing strip. Motor frame 208 then fixes the second motor 209 to prevent it from rotating during operation and affecting the device's operation. The output shaft of the second motor 209 is fixedly connected to a grinding wheel 210 via a coupling, and a pulley is fixedly connected to the outer surface of grinding wheel 210. 211, a belt 212 is driven to the outer surface of pulley 211, and a second pulley 213 is driven to the end of belt 212 away from pulley 211. The second motor 209 drives the grinding wheel 210 to rotate inside the connecting strip 207, thereby grinding the pushed-out sealing strip. At the same time, the grinding wheel 210 drives pulley 211 to rotate, and then pulley 211 drives pulley 213 to rotate through belt 212, thereby driving the grinding wheel 210 on the other side to rotate and grind. A cleaning wheel 214 is rotatably connected to the inner wall of the connecting strip 207. The outer surface of motor frame 201 is fixedly connected to the outer surface of support frame 101, and the outer surface of rack 205 is connected to the outer surface of connecting plate 102. The sliding connection is used, with the outer surface of the push plate 206 slidingly connected to the inner wall of the connecting plate 102. After the sealing strip is polished by the grinding wheel 210, it will pass through the cleaning wheel 214. At this time, the movement of the sealing strip will cause the cleaning wheel 214 to rotate, and then the cleaning wheel 214 will clean the surface of the sealing strip. There are two connecting bars 207 and two grinding wheels 210. The outer surface of the grinding wheel 210 is rotatably connected to the inner wall of the connecting bar 207. The inner wall of the pulley 213 is fixedly connected to the outer surface of the grinding wheel 210. There are two cleaning wheels 214. The connecting bar 207 fixes the position of the grinding wheel 210 to prevent the grinding wheel 210 from disengaging from the device during rotation, thereby affecting the normal operation of the device.

[0031] The fixing mechanism 3 includes a connecting ring 301 fixedly connected to the top of the connecting plate 102. Several connecting rings 301 are provided. A fixing rod 302 is fixedly connected to the top of each connecting ring 301. A spring 303 is fixedly connected to the top of each connecting ring 301, fixing the position of the spring 303 so that the spring 303 can be stretched, thus enabling the spring 303 to quickly return to its original position. The inner side of the spring 303 is sleeved with the outer surface of the fixing rod 302. A pressure plate 304 is fixedly connected to the end of the spring 303 away from the connecting ring 301. The inner wall of the pressure plate 304 is slidably connected to the outer surface of the fixing rod 302. A mold 30 is slidably connected to the bottom of the pressure plate 304. 7. The fixed rod 302 restricts the movement trajectory of the spring 303, preventing the spring 303 from deviating during movement. The pressure plate 304, which can slide on the fixed rod 302, stretches the spring 303, allowing it to reset. The bottom of the mold 307 is slidably connected to the top of the connecting plate 102. Two clamping blocks 308 are slidably connected to the bottom of the pressure plate 304. The outer surface of the clamping blocks 308 contacts the outer surface of the mold 307. The clamping blocks 308 can slide at the bottom of the pressure plate 304, allowing them to clamp molds 307 of different sizes, thus enabling the device to handle sealing strips of different sizes.

[0032] A connecting block 309 is fixedly connected to the top of the clamping block 308. The outer surface of the connecting block 309 is slidably connected to the inner wall of the pressure plate 304. A moving plate 310 is rotatably connected to the inner wall of the connecting block 309. A threaded cylinder 311 is rotatably connected to the end of the moving plate 310 away from the connecting block 309. When the threaded cylinder 311 moves upward, it pulls the moving plate 310. Then, the moving plate 310 drives the connecting block 309 to slide within the pressure plate 304, thereby causing the connecting block 309 to drive the clamping block 308 to move and clamp the mold 307. The inner wall of the threaded cylinder 311 is threaded with a threaded rod 312. The top of the pressure plate 304 is fixedly connected with an L-shaped block 305. The inner wall of the L-shaped block 305 is threaded with a bolt 306. The outer surface of the bolt 306 contacts the outer surface of the threaded rod 312. When the threaded rod 312 is rotated, the threaded cylinder 311 will move upward along the threaded rod 312. The bolt 306, which can be tightened inside the L-shaped block 305, will fix the threaded rod 312 and prevent the clamping block 308 from loosening during the process of pushing out the sealing strip.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, first lift the pressure plate 304 upwards. The pressure plate 304 will then slide on the fixed rod 302, allowing it to stretch the spring 303. Next, place the mold 307 on the connecting plate 102, below the pressure plate 304. Then release the pressure plate 304. The spring 303 will quickly return to its original position, causing the pressure plate 304 to press down on the mold 307. Then, rotate the threaded rod 312. This rotation will cause the threaded cylinder 311 to move upwards, which in turn will drive the moving plate 310 towards... The moving plate 310 pulls the connecting block 309, causing them to move closer together. This allows the connecting block 309 to move the clamping block 308 to clamp the mold 307, thus fixing the mold 307 when the sealing strip is ejected. This ensures a more stable and precise forming process for the sealing strip, preventing minor displacement or deviation of the mold 307 that could lead to inaccurate dimensions of the sealing strip. Then, the bolt 306 is tightened inside the L-shaped block 305, fixing the position of the threaded rod 312. Then, the first motor 202 and the second motor 209 can be started. At this time, the first motor 202 will drive the rotating shaft 203 to rotate, which in turn drives the gear 204 to rotate. The rotation of the gear 204 will cause the rack 205 to move towards the mold 307, which will cause the rack 205 to drive the push plate 206 to move. Then the push plate 206 will push out the sealing strip inside the mold 307. At the same time, the second motor 209 will cause the grinding wheel 210 to rotate inside the connecting strip 207. Then the grinding wheel 210 will drive the pulley 211 to rotate. 211 will drive the pulley 213 to rotate via belt 212, which will drive the grinding wheel 210 on the other side to rotate. The sealing strip will first pass through the grinding wheel 210, where it will grind the surface of the sealing strip. This allows the sealing strip to be ground as it is pushed out of the connecting strip 207, making the edge of the sealing strip more rounded and smooth, thus reducing problems in subsequent processing. Then the sealing strip will pass through the cleaning wheel 214, which will clean the surface of the ground sealing strip.
