Description

Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, specifically to a quick mold replacement device for filter manufacturing. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. It generally refers to automotive filters, which are engine accessories. According to different filtration functions, they are divided into: oil filters, fuel filters, gasoline filters, diesel filters, oil-water separators, hydraulic filters, air filters, and cabin air filters, etc. Engines have three types of filters: air, oil, and fuel, which are generally called "three filters". With the addition of the cabin air filter, it is commonly known as the four filters. They are responsible for filtering the media in the lubrication system, combustion system, engine intake system, and passenger air circulation system, respectively. Filter molds are required in the production and processing of filters.

[0003] However, some existing filter molds are inconvenient to disassemble and assemble during use. The disassembly and assembly process of filter molds is often cumbersome, which increases the molding time and reduces the working efficiency, making them inconvenient for people to use. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a quick mold replacement device for filter production, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick mold replacement device for filter production, comprising a work box, a mold block, and a first motor. A fixed platform is fixedly installed at one end of the work box, and a second pulley shaft is movably installed at one end of the fixed platform. A threaded bushing is movably installed at one end of the second pulley shaft, and guide blocks are fixedly installed at both ends of the threaded bushing. A limiting groove that mates with the guide blocks is opened on the inner side of the second pulley shaft. A limiting ring is movably installed at one end of the threaded bushing, and a threaded connecting shaft is movably installed at one end of the limiting ring. A limiting block that mates with the threaded connecting shaft is fixedly installed on the inner side of the limiting ring. An insert block is movably installed at one end of the threaded connecting shaft, and a guide groove that mates with the insert block is opened at one end of the threaded connecting shaft. A limiting disc is movably installed at one end of the threaded connecting shaft.

[0006] By adopting the above technical solution, when the insert block reaches the position of the limiting hole, the insert block is released from the limiting position. At this time, the threaded connecting shaft continues to be limited by the limiting block. The threaded connecting shaft will stop lifting and start rotating at the same time, so that the insert block moves along the guide groove and is inserted into the limiting hole. With the help of the pneumatic clamp, the mold can be quickly positioned and locked, thereby simplifying the operation steps, shortening the time for changing and fixing, making it easier for workers to use, and improving work efficiency.

[0007] The present invention is further configured such that mounting plates are movably mounted at both ends of the fixed platform, and a roller assembly is movably mounted at one end of the mounting plate. A threaded rod is movably mounted in the middle of the mounting plate, and the threaded rod is connected to the second pulley shaft by a belt. A threaded hole that mates with the threaded bushing is provided at one end of the fixed platform.

[0008] By adopting the above technical solution, the mounting plate provides guidance and support for the roller assembly, and one end of the mounting plate can also be used for quick positioning of the mold.

[0009] The present invention is further configured such that a mold block is movably installed at one end of the fixed platform, and an insert rod is fixedly installed at one end of the mold block. A limiting hole that cooperates with the insert rod is opened at one end of the mold block, and a support leg is fixedly installed at one end of the work box, and the support leg is configured in four sets.

[0010] By adopting the above technical solution and installing support legs, the device can obtain better support and be more stable during operation.

[0011] The present invention is further configured such that a second motor is fixedly installed at one end of the fixed platform, and rotating plates are movably installed at both ends of the fixed platform. A first pulley shaft is fixedly installed at one end of the rotating plate. The second motor and the first pulley shaft are connected by a belt. The first motor and the second pulley shaft are connected by a belt. A through hole is provided at one end of the fixed platform.

[0012] By adopting the above technical solution, the belt connecting the first motor and the second pulley shaft enables better linkage between the various parts of the device, thus improving the structural composition of the device.

[0013] The present invention is further configured such that one end of the limiting plate has an insertion hole that cooperates with the insertion rod, one end of the threaded connecting shaft has a groove that is opposite in direction to the guide groove, and pneumatic clamps are movably installed at both ends of the fixed platform.

[0014] By adopting the above technical solution, the insertion hole is locked by the insertion rod. At the same time, the insertion block reaches the position of the limiting hole, so that the insertion block is released from the limit. At this time, the threaded connecting shaft continues to be limited by the limiting block. The threaded connecting shaft will stop lifting and start rotating, so that the insertion block moves along the guide groove and is inserted into the limiting hole. It works in conjunction with the pneumatic clamp to achieve a quick positioning and locking operation of the mold.

[0015] In summary, the present invention has the following main advantages:

[0016] 1. This utility model, by setting up a limiting plate, insert block, threaded connecting shaft, etc., uses the rotation of the second pulley shaft to cause the limiting groove on the inner side of the second pulley shaft to limit and guide the threaded bushing, so that the threaded bushing moves vertically upward in conjunction with the threaded hole in the middle of the fixed platform. At the same time, the threaded bushing will synchronously lift the limiting ring, so that the threaded connecting shaft is lifted along the bottom of the mold block under the limiting action of the limiting block. When the threaded connecting shaft is lifted a certain distance, the insert hole of the limiting plate will be limited and locked by the insert rod. At the same time, the insert block reaches the position of the limiting hole, so that the insert block is released from the limiting action. At this time, the threaded connecting shaft continues to be limited by the limiting block, and the threaded connecting shaft will stop lifting and start rotating, so that the insert block moves along the guide groove and inserts into the limiting hole. With the help of the pneumatic clamp, the mold can be quickly positioned and locked, thereby simplifying the operation steps, shortening the time for changing and fixing, making it easier for workers to use, and improving work efficiency.

[0017] 2. This utility model, equipped with an installation plate, roller assembly, and threaded rods, allows for mold replacement. First, the pneumatic clamping plate lifts to release the mold's restriction. Simultaneously, the second pulley shaft, through reverse drive, retracts and descends via the threaded connection shaft and other positioning and locking structures, further releasing the mold's restriction. During this process, the second pulley shaft rotates via the threaded rods at both ends of the belt-driven fixed platform, causing the installation plate to move horizontally and rise to a certain height in conjunction with the threaded rods. This allows the roller assembly to lift the mold to be replaced, and the rolling action of the roller assembly enables the mold to be quickly removed and taken away. This achieves the advantage of convenient assembly and disassembly, solving the problem of existing filter molds being inconvenient to assemble and disassemble, often involving cumbersome operations that increase mold forming time and thus hinder user convenience.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A quick-change device for molds used in filter production, such as Figure 1-5 As shown, the assembly includes a work box 1, a mold block 4, and a first motor 5. A fixed platform 3 is fixedly installed at one end of the work box 1, and a second pulley shaft 8 is movably installed at one end of the fixed platform 3. A threaded bushing 20 is movably installed at one end of the second pulley shaft 8, and guide blocks 21 are fixedly installed at both ends of the threaded bushing 20. A limiting groove 19 that mates with the guide block 21 is provided on the inner side of the second pulley shaft 8. A limiting ring 22 is movably installed at one end of the threaded bushing 20, and a threaded connecting shaft 24 is movably installed at one end of the limiting ring 22. A limiting block 23 that mates with the threaded connecting shaft 24 is fixedly installed on the inner side of the limiting ring 22. An insert block 13 is movably installed at one end of the threaded connecting shaft 24, and a notch is provided at one end of the threaded connecting shaft 24. The guide groove 25, which cooperates with the insert block 13, has a limit plate 11 movably installed at one end of the threaded connecting shaft 24. First, the device is started, and then the pneumatic clamping plate 14 is raised to release the limit on the mold. At the same time, the first motor 5 drives the second pulley shaft 8 by belt, so that the second pulley shaft 8 reverses and drives the threaded connecting shaft 24 and other related positioning and locking structures to retract and descend, releasing the limit on the mold. During this process, the second pulley shaft 8 will rotate through the threaded rods 17 at both ends of the belt-driven fixed table 3, so that the mounting plate 16 moves horizontally and is raised to a certain height in cooperation with the threaded rods 17. This allows the roller group 15 to lift the replacement mold, and the rolling transmission of the roller group 15 will quickly remove and take away the mold that needs to be replaced.

[0027] Please see Figure 3Mounting plates 16 are movably mounted at both ends of the fixed platform 3, and a roller assembly 15 is movably mounted at one end of the mounting plate 16. A threaded rod 17 is movably mounted in the middle of the mounting plate 16, and the threaded rod 17 is connected to the second pulley shaft 8 by a belt. A threaded hole 18 that mates with the threaded bushing 20 is opened at one end of the fixed platform 3. By mounting the mounting plate 16, the mounting plate 16 provides guidance and support for the roller assembly 15. At the same time, one end of the mounting plate 16 can also be used for quick positioning of the mold.

[0028] Please see Figure 1 A mold block 4 is movably installed at one end of the fixed platform 3, and an insertion rod 27 is fixedly installed at one end of the mold block 4. A limiting hole 26 that cooperates with the insertion block 13 is opened at one end of the mold block 4. A support leg 2 is fixedly installed at one end of the work box 1, and the support leg 2 is set in four sets. By installing the support leg 2, the device can obtain better support force and be more stable when the device is in operation.

[0029] Please see Figure 1 A second motor 6 is fixedly installed at one end of the fixed platform 3, and rotating plates 9 are movably installed at both ends of the fixed platform 3. A first pulley shaft 7 is fixedly installed at one end of the rotating plate 9. The second motor 6 and the first pulley shaft 7 are connected by a belt. The first motor 5 and the second pulley shaft 8 are connected by a belt. A through hole 10 is opened at one end of the fixed platform 3. The first motor 5 and the second pulley shaft 8 are connected by a belt, thereby realizing better linkage of the various parts of the device and improving the structural composition of the device.

[0030] Please refer to the figure. One end of the limiting plate 11 has an insertion hole 12 that mates with the insertion rod 27. One end of the threaded connecting shaft 24 has a groove in the opposite direction to the guide groove 25. Pneumatic clamping plates 14 are movably installed at both ends of the fixed platform 3. By installing the insertion hole 12, the insertion hole 12 is limited and locked by the insertion rod 27. At the same time, the insertion block 13 reaches the position of the limiting hole 26, so that the insertion block 13 is released from the limit. At this time, the threaded connecting shaft 24 continues to be limited by the limiting block 23. The threaded connecting shaft 24 will stop lifting and start rotating, so that the insertion block 13 moves along the guide groove 25 and is inserted into the limiting hole 26. Together with the pneumatic clamping plate 14, the mold can be quickly positioned and locked.

[0031] The working principle of this utility model is as follows: In use, the device is first started, then the pneumatic clamp 14 is raised to release the mold's restriction. Simultaneously, the first motor 5 drives the second pulley shaft 8 via belt, causing the second pulley shaft 8 to reverse and drive the threaded connection shaft 24 and other related positioning and locking structures to retract and descend, releasing the mold's restriction. During this process, the second pulley shaft 8 rotates via the threaded rods 17 at both ends of the belt-driven fixed platform 3, causing the mounting plate 16 to move horizontally and rise to a certain height in conjunction with the threaded rods 17. This allows the roller assembly 15 to lift the replacement mold, and the roller assembly 15, through its rolling transmission, quickly removes and takes away the mold to be replaced. Then, the required mold is placed on the fixed platform 3 under the same operation and positioned at one end of the mounting plate 16. The first motor 5 drives the second pulley shaft 8 to rotate via belt, causing the limiting groove 19 on the inner side of the second pulley shaft 8 to limit and guide the threaded bushing 20, thus releasing the threaded connection shaft 24. The bushing 20 moves vertically upwards in conjunction with the threaded hole 18 in the middle of the fixed platform 3. At the same time, the threaded bushing 20 will simultaneously lift the limiting ring 22, causing the threaded connecting shaft 24 to rise along the bottom of the mold block 4 under the limiting action of the limiting block 23. When the threaded connecting shaft 24 rises a certain distance, the insertion hole 12 of the limiting plate 11 will be limited and locked by the insertion rod 27. At the same time, the insertion block 13 reaches the position of the limiting hole 26, causing the insertion block 13 to be released from the limiting action. At this time, the threaded connecting shaft 24 continues to be limited by the limiting block 23. The threaded connecting shaft 24 will stop rising and start to rotate, causing the insertion block 13 to move along the guide groove 25 and insert into the limiting hole 26. With the help of the pneumatic clamping plate 14, the mold can be quickly positioned and locked. At the same time, the mold's operating angle can be quickly adjusted by the second motor 6 driving the first pulley shaft 7 to drive the rotating plate 9, which is convenient for the operator.
