Description

Technical Field

[0001] This utility model relates to the field of valve manufacturing technology, and in particular to a pneumatic gate valve forming mold. Background Technology

[0002] Pneumatic gate valve forming molds are key process equipment used in the valve manufacturing industry for processing and producing pneumatic gate valves. In the conventional production process, the mold parts in the forming mold need to be precisely and securely mounted on the worktable or machining platform. The positioning accuracy and fixing firmness of the mold directly affect the quality of subsequent forming processes and the pass rate of the final product.

[0003] Currently, the methods used to fix such mold parts in related technologies generally suffer from cumbersome operation procedures and low positioning accuracy. When installing mold parts, operators often need to use external tools for repeated manual centering and calibration. This process is not only time-consuming and labor-intensive, but also prone to positioning deviations due to human error, resulting in inaccurate positioning and difficulty in centering.

[0004] After initial positioning, the subsequent fixing operations are often quite complex. For example, using traditional bolt tightening methods requires operators to tighten multiple bolts distributed around the mold part one by one. This not only makes the fixing operation cumbersome and time-consuming, but also makes it difficult to ensure uniform stress on all fixing points. During the mold's operation, vibration or impact may cause individual bolts to loosen, leading to unreliable locking of the entire mold part and affecting processing stability. Similarly, when it is necessary to replace or maintain the mold part, the disassembly process is also time-consuming and laborious, severely restricting overall production efficiency. Therefore, this utility model proposes a pneumatic gate valve forming mold to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pneumatic gate valve forming mold, which aims to improve the problems of inaccurate positioning, difficulty in centering, and cumbersome and time-consuming fixing operations in some existing pneumatic gate valve forming molds.

[0006] Part Two: Core Technology Solutions This utility model provides a pneumatic gate valve forming mold, comprising: a worktable with a groove; and a mold component detachably placed on the worktable. The mold also includes a positioning mechanism and a fixing mechanism. The positioning mechanism is disposed on the worktable and includes multiple clamping blocks, two sliding blocks fixed to the bottom of each clamping block, and a second spring for driving the sliding blocks. The second spring pushes the sliding blocks to move towards each other, causing the clamping blocks to clamp the mold component. The fixing mechanism includes an operable rotating rod, a fixing block linked to the rotating rod, and a first spring as part of the clamping assembly. The second spring pushes the clamping blocks to move towards each other to clamp the mold component; the fixing block is used to insert into the groove of the worktable, the rotating rod is used to drive the fixing block to rotate after insertion, and the first spring is used to push the fixing block upwards after rotation, causing it to engage with the groove.

[0007] Part Three: Preferred Technical Solutions Preferably, the positioning mechanism further includes a sliding block and a guide rod, the clamping block is fixedly connected to the sliding block, and the sliding block is slidably connected to the guide rod.

[0008] Preferably, the spring is sleeved on the guide rod and is used to abut against the sliding block to provide thrust; and the worktable is provided with a groove, and the sliding block is slidably engaged in the groove.

[0009] Preferably, the fixing mechanism further includes a fixing frame and a protective shell; multiple fixing frames are fixedly connected to the mold part, the protective shell covers the fixing frame, and the rotating rod is rotatably connected to the protective shell.

[0010] Preferably, the fixing mechanism further includes a sliding column, which is vertically slidably connected inside the protective shell. A rotating rod is fixedly connected to the upper end of the sliding column, and the fixing block is fixedly connected to the lower end of the sliding column.

[0011] Preferably, the fixing mechanism further includes a support block, which is fixedly connected to the inner wall of the protective shell.

[0012] Preferably, the clamping assembly further includes a retaining ring, which is fixedly connected to the sliding column, and the spring is disposed between the retaining ring and the bearing surface of the protective shell.

[0013] Preferably, the support block is used to abut against the fixing frame from top to bottom when the fixing block is locked with the groove, so as to form a lock in conjunction with the upward clamping force of the fixing block.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a positioning mechanism, uses spring-driven clamping blocks and sliding blocks to automatically clamp the mold parts, solving the problems of inaccurate positioning and difficulty in centering during mold part installation in the prior art, achieving the technical effect of rapid and accurate positioning, and laying the foundation for subsequent stable fixing.

[0015] 2. This utility model, by setting a fixing mechanism, uses a rotating rod to control the fixing block to perform a "downward rotation" action, and relies on the upward counter-pushing force released by the spring to make the fixing block clamp in the groove of the worktable in the opposite direction. At the same time, the support block presses down to tighten the fixing frame to form a lock, which solves the problems of cumbersome, time-consuming and unreliable locking of the mold fixing operation in the prior art, and achieves the technical effect of fast locking and stable clamping.

[0016] 3. This utility model can quickly unlock the mold by pressing the rotating rod again during disassembly to counteract the clamping force of the spring and rotating the rotating rod to return the fixed block to its original alignment. This solves the problem of difficult and laborious mold disassembly in the prior art, achieves the technical effect of convenient disassembly, significantly reduces the difficulty of operation, and improves the efficiency of mold replacement.

Detailed Implementation

[0019] 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.

[0020] Example: Reference Figures 1 to 5 This utility model provides a pneumatic gate valve forming mold, which aims to solve the problems of inaccurate clamping and positioning, cumbersome fixing operation, unreliable locking and difficult disassembly of the existing pneumatic gate valve forming mold.

[0021] like Figure 1 As shown, it includes a workbench 1 and a mold component 4 that is detachably placed on the workbench 1. The workbench 1 serves as the mounting base for the entire device and has grooves 282 and slides 35. The mold component 4 is used for the forming and processing of the pneumatic gate valve.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The mold also includes a positioning mechanism 3, which is set on the worktable 1. The positioning mechanism 3 includes multiple clamping blocks 32, sliding blocks 31, guide rods 33, and springs 34. The bottom end of each clamping block 32 is fixedly connected to two sliding blocks 31. The sliding blocks 31 are slidably connected to the guide rods 33 and are also slidably fitted in the grooves 35 of the worktable 1. The springs 34 are sleeved on the guide rods 33 and are used to abut against the sliding blocks 31. The springs 34 push the sliding blocks 31 to drive the clamping blocks 32 to move towards each other to clamp the mold part 4.

[0023] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The grinding tool also includes a fixing mechanism 2, which includes an operable rotating rod 24, a fixing block 26 linked to the rotating rod 24, and a clamping assembly 28. The clamping assembly 28 includes a spring 281. The fixing block 26 is used to insert into the groove 282 of the worktable 1. The rotating rod 24 is used to drive the fixing block 26 to rotate after it inserts into the groove 282. The spring 281 is used to push the fixing block 26 upward after it rotates, so that it is clamped with the groove 282.

[0024] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5The structure of the fixing mechanism 2 is described in detail below: The fixing mechanism 2 includes a fixing frame 21 and a protective shell 22. Multiple fixing frames 21 are fixedly connected to the mold part 4. The protective shell 22 covers the fixing frames 21. The fixing mechanism 2 also includes a rotating rod 24, which is rotatably connected to the protective shell 22. The fixing mechanism 2 also includes a sliding column 23, which is vertically slidably connected inside the protective shell 22. The upper end of the sliding column 23 is fixedly connected to the rotating rod 24. The fixing mechanism 2 also includes a fixing block 26, which is fixedly connected to the sliding column 23. At the lower end of 3, the fixing mechanism 2 also includes a support block 25, which is fixedly connected to the inner wall of the protective shell 22. The fixing mechanism 2 also includes a clamping assembly 28, which includes a fixing ring 27 and a spring 281. The fixing ring 27 is fixedly connected to the sliding column 23, and the spring 281 is disposed between the fixing ring 27 and the bearing surface of the protective shell 22 for pushing the fixing ring 27 upward. In the fixed state, the support block 25 is used to abut against the fixing frame 21 from top to bottom to cooperate with the upward clamping force of the fixing block 26 on the groove 282 to form a lock.

[0025] Reference Figure 1 and Figure 2 The positioning mechanism 3 also includes a sliding block 31 and a guide rod 33. A clamping block 32 is fixedly connected to the sliding block 31, and the sliding block 31 is slidably connected to the guide rod 33. A spring 34 is sleeved on the guide rod 33 and is used to abut against the sliding block 31 to provide thrust. Furthermore, a groove 35 is provided on the worktable 1, and the sliding block 31 is slidably fitted into the groove 35. Reference Figure 1 , Figure 3 and Figure 4 The support block 25 abuts against the fixed frame 21 from top to bottom, and the fixed block 26 is locked in the groove 282 from bottom to top. The support block 25 and the fixed block 26 cooperate to form an upper and lower locking between the fixed frame 21 and the worktable 1.

[0026] The implementation principle of this embodiment is as follows: During the mold installation process, the operator first needs to align the fixing frame 21 fixed on the mold part 4 with the groove 282 on the worktable 1, and then place the fixing frame 21 stably on the upper surface of the worktable 1; after the positioning calibration is completed by the positioning mechanism 3, the protective shell 22 is then placed on the upper surface of the fixing frame 21. At this time, the fixing block 26 of the protective shell 22 will be inserted into the preset slot of the fixing frame 21. Next, the operator presses down the rotating rod 24, and the rotating rod 24 will push the sliding column 23 to slide down along the inner wall of the fixing ring 27, wherein the support block 25 is pre-fixed on the inner wall of the protective shell 22; during the downward movement of the sliding column 23, the sliding column 23 will drive the fixing block 26 and the fixing ring 27 to move downward synchronously. During the movement, the fixing ring 27 will squeeze the spring 281 downward. After the spring 281 included in the clamping assembly 28 is compressed, it will generate an upward thrust. When the fixing block 26 passes through the fixing frame 21 from top to bottom and is fully inserted into the groove 282 of the worktable 1, the upper surface of the fixing block 26 will be in close contact with the outer wall of the groove 282. At this time, the lower surface of the support block 25 is in contact with the upper surface of the fixing frame 21. The operator then rotates the rotating rod 24 to a preset angle, so that the outer wall of the fixing block 26 is misaligned with the slot on the fixing frame 21, and then releases the pressure on the rotating rod 24. The spring 281 then releases the accumulated elastic force, pushing the fixing ring 27 upward. The fixing ring 27 drives the fixing block 26 and the support block 25 to move upward through the sliding column 23, so that the fixing block 26 is continuously clamped upward in the groove 282, and finally the fixing operation of the mold part 4 is completed. During mold disassembly, the operator first needs to press down on the rotating rod 24, pushing the sliding column 23 to move downwards. Simultaneously, this causes the fixing block 26 and the fixing ring 27 to move downwards as well. At this time, the fixing ring 27 will press down on the spring 281 to counteract its upward thrust, thus releasing the clamping state of the fixing block 26 in the groove 282. Next, the rotating rod 24 is rotated back to its initial angle, realigning the outer wall of the fixing block 26 with the slot on the fixing frame 21. Then, the pressure on the rotating rod 24 is released. When the spring 281 is pressed, it releases its elastic force to push the fixing ring 27, the sliding column 23 and the fixing block 26 upward, so that the fixing block 26 is dislodged from the groove 282 of the workbench 1 and the slot of the fixing frame 21. Then, the protective shell 22 covering the fixing frame 21 is removed, and finally the fixing frame 21 on the mold part 4 is removed from the upper surface of the workbench 1, completing the disassembly operation of the entire mold. By operating the fixing mechanism 2, the operator can quickly fix and easily disassemble the mold part 4, which significantly improves the efficiency of mold assembly and disassembly and reduces the difficulty of replacement operation.

[0027] During the operation of the positioning mechanism 3, multiple clamping blocks 32 are first moved away from the center of the worktable 1. The clamping blocks 32 drive the sliding block 31 to move in the same direction as the outer wall of the guide rod 33. At the same time, the sliding block 31 compresses the second spring 34 in the direction of movement. The second spring 34 provides a thrust in the opposite direction of movement for the sliding block 31, leaving space for the mold part 4 to be placed stably on the upper surface of the worktable 1. After the force on the clamping block 32 is released, the second spring 34 begins to release its elasticity. The second spring 34 pushes the sliding block 31 to slide closer to the mold part 4. The sliding block 31 drives the clamping block 32 to gradually fit against the outer wall of the mold part 4 until it is clamped. During this process, the sliding block 31 moves synchronously along the inner wall of the groove 35. As a key limiting structure, the groove 35 can accurately constrain the movement path of the sliding block 31. Finally, under the continuous release of the elastic force of the spring 34, the clamping block 32 fits tightly against the outer wall of the mold part 4, thereby stably limiting the mold part 4 to the preset position on the worktable 1. By operating the positioning mechanism 3, the operator achieves stable limiting of the mold part 4 at the preset position on the worktable 1, ensuring the accuracy of the installation and positioning of the mold part 4, thereby reducing the positioning deviation and laying the foundation for the subsequent stable fixing of the mold part 4 by the fixing mechanism 2 and the subsequent pneumatic gate valve forming processing accuracy.
