Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump technology, and in particular to a high-efficiency hydraulic drive structure for mold sealing. Background Technology

[0002] Against the backdrop of rapid development in industrial automation and intelligent manufacturing, molds, as core production equipment in fields such as automobile manufacturing, engineering machinery, and aerospace, directly determine product precision, production efficiency, and equipment lifespan through their sealing performance. Hydraulic drive structures, with their advantages of smooth power transmission, strong load capacity, and high control precision, have become the mainstream technical solution for achieving efficient mold sealing and are widely used in key processes such as mold closing sealing and cavity pressure holding.

[0003] In traditional mold sealing, the sealing effect of the mold is achieved by manually turning the nut. This is time-consuming, labor-intensive, and slow in producing workpieces. Moreover, when the hydraulic system malfunctions, such as a broken connecting pipe or worn internal parts of the hydraulic pump, disassembly is inconvenient, making it difficult for maintenance personnel to quickly inspect and replace the faulty parts. This may require a lot of time to disassemble, resulting in prolonged equipment downtime and affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency hydraulic drive structure for mold sealing. By pulling the pull rod, the slider moves, which in turn drives the rotating block to rotate. The rotating block then moves the insert plate out of the fixed hole. At this point, the mating head is pulled out of the connector head, allowing maintenance personnel to quickly remove and replace faulty components when the hydraulic system malfunctions, reducing equipment downtime and minimizing the impact on production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency hydraulic drive structure for mold sealing includes: a manual hydraulic pump connected to a main body; a connector fixedly connected to the left end of the manual hydraulic pump; fixed boxes fixedly connected to both sides of the outer wall of the connector; a pull rod slidably connected to the inner wall of each fixed box; a slider fixedly connected to the opposite end of each pull rod; rotating blocks rotatably connected to both sides of the outer wall of each slider; insert plates rotatably connected to the outer wall of each rotating block; a first spring provided between the fixed box and the inner wall of the slider; a mating head slidably connected to the inner wall of the connector; connecting plates fixedly connected to both sides of the outer wall of the mating head; and a limit component provided at the top of the manual hydraulic pump.

[0006] Furthermore, one end of each of the first springs is connected to the slider, and the other end of each of the first springs is connected to the inner wall of the fixed box.

[0007] Furthermore, the outer walls of the sliders are all slidably connected to the inner walls of the fixed box, and the outer walls of the inserts are all slidably connected to the inner walls of the fixed box.

[0008] Furthermore, a sealing ring is fixedly connected to the inner wall of the connector, and a connecting pipe is fixedly connected to the left end of the mating head.

[0009] Furthermore, the inner wall of the connecting plate is provided with multiple fixing holes corresponding to the insert plate.

[0010] Furthermore, the limiting component includes a connecting column fixedly connected to the top of the manual hydraulic pump, a lower mating plate fixedly connected to the top of the connecting column, an upper mating plate rotatably connected to the top of the lower mating plate, a fixing plate fixedly connected to the top of the upper mating plate, a connecting frame fixedly connected to the front end of the lower mating plate, a sliding rod slidably connected to the inner wall of the connecting frame, a sliding plate fixedly connected to the outer wall of the sliding rod, and a second spring provided between the inner wall of the connecting frame and the sliding plate.

[0011] Furthermore, the inner wall of the fixing plate is provided with a connecting hole corresponding to the slide rod, and the outer wall of the slide plate is slidably connected to the inner wall of the connecting frame.

[0012] Furthermore, one end of the second spring is connected to the slide plate, and the other end of the second spring is connected to the inner wall of the connecting frame.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by pulling the pull rod, the slider is moved, the slider drives the rotating block to rotate, and the rotating block drives the insert plate to move out of the fixed hole. At this time, the mating head is pulled to disengage it from the connector head. This allows maintenance personnel to quickly remove and inspect and replace faulty parts when the hydraulic system malfunctions, reducing equipment downtime and minimizing the impact on production.

[0014] 2. In this utility model, by pulling the slide rod and then rotating the upper mating plate to mate with the lower mating plate, when the mating is complete, the fixing plate will insert into the lower mating plate. Then, the slide rod is released. When the slide rod is released, the second spring will bounce the slide plate. When the slide plate bounces, it will drive the slide rod to insert into the connecting hole and fix it. This can prevent the handle from moving accidentally when not in operation, avoid the sudden start of the hydraulic system or pressure change caused by misoperation of the handle, prevent the mold from opening and closing accidentally or other dangerous situations, and ensure the safety of operators and equipment.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-efficiency hydraulic drive structure for mold sealing, comprising: a manual hydraulic pump 1 connected to a main body; a connector 2 fixedly connected to the left end of the manual hydraulic pump 1; fixed boxes 3 fixedly connected to both sides of the outer wall of the connector 2; pull rods 4 slidably connected to the inner walls of the fixed boxes 3; sliders 5 fixedly connected to opposite ends of the pull rods 4; rotating blocks 6 rotatably connected to both sides of the outer wall of the sliders 5; insert plates 7 rotatably connected to the outer walls of the rotating blocks 6; and a first spring 8 provided between the inner walls of the fixed boxes 3 and the sliders 5. A mating head 10 is connected, and connecting plates 11 are fixedly connected to both sides of the outer wall of the mating head 10. A limit component is provided at the top of the manual hydraulic pump 1. One end of the first spring 8 is connected to the slider 5, and the other end of the first spring 8 is connected to the inner wall of the fixed box 3. The outer wall of the slider 5 is slidably connected to the inner wall of the fixed box 3. The outer wall of the insert plate 7 is slidably connected to the inner wall of the fixed box 3. A sealing ring 9 is fixedly connected to the inner wall of the connecting head 2. A connecting pipe 22 is fixedly connected to the left end of the mating head 10. Multiple fixing holes 12 are provided on the inner wall of the connecting plate 11 corresponding to the insert plate 7.

[0019] Specifically, when disassembling the connecting pipe 22 from the manual hydraulic pump 1, the pull rod 4 must be pulled first. The force of the pull rod 4 drives the slider 5 to move along a preset trajectory. As the slider 5 moves, it synchronously drives the rotating block 6 to rotate. The rotation of the rotating block 6 further drives the insert plate 7 to move. When the insert plate 7 moves completely out of the fixed hole 12, the fixed constraint between the connecting pipe 22 and the manual hydraulic pump 1 is released. The operator can then directly pull the mating head 10 to smoothly detach it from the inside of the connector 2. This disassembly structure design allows maintenance personnel to quickly remove the faulty components in the event of a sudden hydraulic system failure, and promptly carry out inspection and replacement work, effectively shortening equipment downtime and minimizing interference with normal production processes. In the subsequent installation stage, simply insert the mating head 10 precisely into the inside of the connector 2, and then release the previously pulled pull rod 4. When the pull rod 4 is released, the first spring 8 will spring back against the slider 5. The hydraulic force pushes the slider 5 to reset. During the reset process, the slider 5 will move the insert plate 7 again until the insert plate 7 is fully inserted into the fixing hole 12, thereby achieving a stable connection between the connecting pipe 22 and the manual hydraulic pump 1 and completing the installation operation. In addition, the sealing ring 9 in this connection structure is made of nitrile rubber. This material has excellent oil resistance and can be used not only with petroleum-based hydraulic oil but also with non-flammable hydraulic oil and other common hydraulic media, effectively avoiding hydraulic oil leakage. At the same time, nitrile rubber also has good wear resistance and elasticity, which can maintain a stable sealing effect during long-term use, extend the service life of the sealing ring, and ensure the reliable operation of the hydraulic system. During sealing, the manual hydraulic pump 1 replaces the traditional manual turning of the nut. The hydraulic driving force output by the manual hydraulic pump 1 is precisely applied to the mold sealing actuator. This driving force can be smoothly transmitted to the contact surface of the mold and the workpiece, so that the two can quickly form a tight seal. Compared with the tedious operation of manually turning the nut, the hydraulic drive mode significantly reduces the intensity of manual operation, shortens the sealing operation time, and ultimately doubles the mold sealing efficiency.

[0020] Reference Figure 1 , Figure 4 and Figure 5The limiting assembly includes a connecting column 13 fixedly connected to the top of the manual hydraulic pump 1. A lower mating plate 14 is fixedly connected to the top of the connecting column 13. An upper mating plate 15 is rotatably connected to the top of the lower mating plate 14. A fixing plate 16 is fixedly connected to the top of the upper mating plate 15. A connecting frame 17 is fixedly connected to the front end of the lower mating plate 14. A slide rod 18 is slidably connected to the inner wall of the connecting frame 17. A slide plate 19 is fixedly connected to the outer wall of the slide rod 18. A second spring 20 is provided between the inner walls of the connecting frame 17 and the slide plate 19. A connecting hole 21 is provided on the inner wall of the fixing plate 16 corresponding to the slide rod 18. The outer wall of the slide plate 19 is slidably connected to the inner wall of the connecting frame 17. One end of the second spring 20 is connected to the slide plate 19, and the other end of the second spring 20 is connected to the inner wall of the connecting frame 17.

[0021] Working principle: When it is necessary to disassemble the connecting pipe 22 and the manual hydraulic pump 1, pull the lever 4 to move the slider 5. As the slider 5 moves, it drives the rotating block 6 to rotate, which in turn moves the insert plate 7. When the insert plate 7 moves, it disengages from the fixing hole 12. At this point, pull the mating head 10 to disengage from the connecting head 2. This allows maintenance personnel to quickly remove and inspect or replace faulty components when a hydraulic system malfunction occurs, reducing equipment downtime and minimizing production impact. During installation, insert the mating head 10 into the connecting head 2, then release the lever 4. When the lever 4 is released, the first spring 8 will spring the slider 5. As the slider 5 springs, it drives the insert plate 7 to insert into the fixing hole 12 for fixation. The sealing ring 9 is made of nitrile rubber, which has good... It has good oil resistance and can adapt to various hydraulic media such as petroleum-based hydraulic oil and non-flammable hydraulic oil. It also has a certain degree of wear resistance and elasticity. When the manual hydraulic pump 1 is finished using, place the handle on the manual hydraulic pump 1 on the lower mating plate 14. At this time, pull the slide rod 18 and rotate the upper mating plate 15 to make it engage with the lower mating plate 14. When engaged, the fixing plate 16 will be inserted into the interior of the lower mating plate 14. Then release the slide rod 18. When the slide rod 18 is released, the second spring 20 will bounce the slide plate 19. When the slide plate 19 is bounced, it will drive the slide rod 18 to be inserted into the connecting hole 21 for fixation. This can prevent the handle from moving accidentally when not in operation, avoid sudden start-up of the hydraulic system or pressure change due to misoperation of the handle, prevent accidental opening and closing of the mold or other dangerous situations, and ensure the safety of operators and equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
