[0002] Electric control valves are key actuators in industrial automation process control, offering advantages such as energy saving, environmental friendliness, and quick and easy installation. As a crucial component of industrial automation control systems, their role and advantages cannot be ignored. From energy saving and environmental protection to precise control, the multiple advantages of electric control valves have led to their widespread application in various industrial production fields. To ensure their normal operation and extend their service life, proper selection, installation, and maintenance are particularly important.

[0003] Most existing electric control valves use nuts to fix the actuator and valve body during installation. This makes the installation and disassembly process too complicated. Furthermore, when installing the locking block, the bolts need to be rotated frequently, which increases the workload of workers. Utility Model Content

[0004] To address the problem of overly complex operation of the actuator, valve body, and mounting block, this utility model aims to provide an electrically adjustable valve for die-casting machines.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an electrically adjustable valve for a die-casting machine, comprising a valve body, a top plate fixedly provided on the top of the valve body, a base plate fixedly provided on the bottom of the valve body, a bracket movably mounted on the upper surface of the top plate, an installation assembly provided inside the bracket, an actuator fixedly provided at the top of the bracket, symmetrically distributed X-shaped plates movably arranged inside the top plate and the bracket, a cylinder rotatably provided inside the X-shaped plate, a first spring fixedly provided on the opposite side of the X-shaped plate, symmetrically distributed limiting blocks fixedly provided at the top of the X-shaped plate, and the lower surface of the limiting blocks... The X-shaped plate is fitted to the inside of the bracket. Symmetrically distributed fixing blocks are fixed on the outer side of the X-shaped plate. The upper surface of the fixing blocks is fitted to the lower surface of the top plate. Symmetrically distributed third through holes are opened inside the X-shaped plate. Symmetrically distributed circular blocks are fixed on the upper surface of the top plate. Symmetrically distributed first grooves are opened at the bottom of the bracket. The circular blocks are movably locked inside the first grooves. Symmetrically distributed first through holes are opened at the bottom of the bracket. Symmetrically distributed second through holes are opened inside the top plate. The first through holes and the second through holes are connected. The X-shaped plate is movably locked inside the first through holes and the second through holes.

[0006] Preferably, the mounting assembly includes a first locking block, on the outer side of which are symmetrically distributed rectangular blocks. A second spring is disposed inside each rectangular block, and a movable block is fixed to one end of the second spring. The outer side of the first locking block is engaged with the second locking block. The inner side of the second locking block has symmetrically distributed third grooves, and the outer side of the rectangular blocks is movably connected to the inner side of the third grooves. The inner side of the second locking block has a fourth groove, and the movable block is movably engaged within the fourth groove. The inner side of the rectangular block has a second groove, and one end of the second spring is fixedly connected to the inner side of the second groove. The outer side of the movable block is movably connected to the inner side of the second groove. The inner side of the second locking block has symmetrically distributed fifth grooves, and a movable plate is slidably disposed within the fifth groove. One end of the movable block is an inclined surface.

[0007] Preferably, the actuator has a first circular shaft inside, the valve body has a second circular shaft at the top, the bottom of the first circular shaft has a first fixing plate fixedly installed, the outer side of the second circular shaft has a second fixing plate fixedly installed, and the second locking block has symmetrically distributed movable columns inside, one end of the movable column movably passing through the first fixing plate, the second fixing plate and the first locking block.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. By setting up an X-shaped plate, a first spring, a limiting block, and a fixing block, the X-shaped plate is squeezed. The squeezing force causes the first spring to contract, which causes the limiting block and the fixing block to move in opposite directions, allowing the X-shaped plate to be removed from the first and second through holes. This facilitates the disassembly and installation of the bracket and the top plate, thereby enabling the installation and disassembly of the valve body and the actuator. The operation is convenient and reduces the workload of workers.

[0010] 2. By setting the installation components, the first locking block is pushed, which drives the rectangular block and the movable block to move. The movable block is pressed against the outside of the second locking block. The pressing force causes the second spring to compress and drive the movable block to move along the second groove. When the rectangular block moves into the third groove, the second spring restores its deformation, causing the movable block to lock into the fourth groove. This can quickly fix the first and second locking blocks, making the operation convenient. Attached Figure Description

[0022] 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.

[0023] Example: Figure 1-9As shown, this utility model provides an electrically adjustable valve for a die-casting machine, including a valve body 1. A top plate 6 is fixedly mounted on the top of the valve body 1, and a base plate 2 is fixedly mounted on the bottom of the valve body 1. A bracket 4 is movably mounted on the upper surface of the top plate 6. An installation assembly 5 is provided inside the bracket 4. An actuator 3 is fixedly mounted on the top of the bracket 4. Symmetrically distributed X-shaped plates 11 are movably arranged inside the top plate 6 and the bracket 4. A cylinder 13 is rotatably mounted inside the X-shaped plate 11. A first spring 14 is fixedly mounted on the opposite side of the X-shaped plate 11. Symmetrically distributed... The limiting block 16 has its lower surface fitted to the interior of the bracket 4. Symmetrically distributed fixing blocks 15 are fixed to the outer side of the X-shaped plate 11, with the upper surface of the fixing blocks 15 fitted to the lower surface of the top plate 6. Symmetrically distributed third through holes 12 are opened inside the X-shaped plate 11. By setting up the X-shaped plate 11, the first spring 14, the limiting block 16, and the fixing blocks 15, the X-shaped plate 11 is compressed. The compression force causes the first spring 14 to contract, causing the limiting block 16 and the fixing block 15 to move in opposite directions, allowing the X-shaped plate 11 to be removed from the first through hole 7 and the second through hole 8, facilitating... The bracket 4 and top plate 6 are disassembled and installed, thereby enabling the installation and disassembly of the valve body 1 and actuator 3. This convenient operation reduces the workload for workers. When the X-shaped plate 11 is pressed, the width of the limiting block 16 and the fixing block 15 is smaller than the width of the first through hole 7 and the second through hole 8. Symmetrically distributed circular blocks 9 are fixed on the upper surface of the top plate 6. Symmetrically distributed first grooves 10 are opened at the bottom end of the bracket 4. The circular blocks 9 are movably engaged inside the first grooves 10. By setting the circular blocks 9 and the first grooves 10, workers can engage the circular blocks 9 by inserting them into the first grooves 10. The first through hole 7 and the second through hole 8 are connected inside the bracket 4, which facilitates the subsequent installation of the valve body 1 and the actuator 3. The bottom of the bracket 4 has symmetrically distributed first through holes 7, and the top plate 6 has symmetrically distributed second through holes 8. The first through holes 7 and the second through holes 8 are connected. The X-shaped plate 11 is movably locked inside the first through holes 7 and the second through holes 8. By setting the first through holes 7 and the second through holes 8, the X-shaped plate 11 is locked into the first through holes 7 and the second through holes 8, thereby fixing the bracket 4 and the top plate 6, and thus fixing the valve body 1 and the actuator 3.

[0024] Mounting assembly 5 includes a first locking block 17. Symmetrically distributed rectangular blocks 19 are fixed to the outer side of the first locking block 17. A second spring 20 is disposed inside the rectangular blocks 19. A movable block 22 is fixed to one end of the second spring 20. A second locking block 18 is locked to the outer side of the first locking block 17. A symmetrically distributed third groove 23 is formed inside the second locking block 18. The outer side of the rectangular blocks 19 is movably connected to the interior of the third groove 23. A fourth groove 24 is formed inside the second locking block 18. The movable block 22 is movably locked inside the fourth groove 24. By setting up mounting assembly 5, pushing the first locking block 17 causes the rectangular blocks 19 and the movable block 22 to move. The movable block 22 presses against the outer side of the second locking block 18. The pressing force compresses the second spring 20 and causes the movable block 22 to move inward along the second groove 21. When the rectangular block 19 moves into the third groove 23, the second spring 20 is engaged with the second locking block 17. The second spring 20 recovers its deformation, causing the movable block 22 to engage in the fourth groove 24, allowing for quick and easy fixation of the first locking block 17 and the second locking block 18. The rectangular block 19 has a second groove 21 inside, with one end of the second spring 20 fixedly connected to the inside of the second groove 21. The outer side of the movable block 22 is movably connected to the inside of the second groove 21. The second groove 21 allows the movable block 22 to move stably. The second locking block 18 has symmetrically distributed fifth grooves 25 inside, with a movable plate 26 slidingly mounted inside. By using the fifth groove 25 and the movable plate 26, moving the movable plate 26 causes the second spring 20 to compress the movable block 22, moving it into the second groove 21, facilitating the disassembly of the first locking block 17 and the second locking block 18. One end of the movable block 22 is a slope, facilitating its engagement in the fifth groove 25.

[0025] The actuator 3 has a first circular shaft 28 inside, and the valve body 1 has a second circular shaft 29 at the top. The bottom of the first circular shaft 28 is fixedly provided with a first fixing plate 30, and the outside of the second circular shaft 29 is fixedly provided with a second fixing plate 31. The second locking block 18 has symmetrically distributed movable columns 27 inside. One end of the movable column 27 can be moved through the first fixing plate 30, the second fixing plate 31 and the first locking block 17. By setting the movable column 27, the first fixing plate 30 and the second fixing plate 31, and cooperating with the mounting component 5, the fixation between the first circular shaft 28 and the second circular shaft 29 can be better realized, and the operation is convenient.

[0026] Working principle: First, push the first locking block 17, which moves the rectangular block 19 and the movable block 22. The movable block 22 presses against the outer side of the second locking block 18. The pressing force compresses the second spring 20 and moves the movable block 22 along the second groove 21. When the rectangular block 19 moves into the third groove 23, the second spring 20 returns to its original shape, causing the movable block 22 to engage in the fourth groove 24. This allows for quick installation and removal of the first locking block 17 and the second locking block 18, making operation convenient. Next, install the movable column 27 on the second locking block 18, cooperating with the mounting component 5 to better achieve the connection between the first round shaft 28 and the second round shaft 29. Finally, align the round block 9 with the first groove 10, and move the bracket 4 downward so that the round block 9 is inserted into the first groove 10. At this time, the first through hole 7 is aligned with the second through hole 8. Use a tool to press the outer side of the X-shaped plate 11. The pressing force causes the first spring 14 to compress and generate elastic force, which drives the limiting block 16 and the fixing block 15 to move in opposite directions, inserting the X-shaped plate 11 into the first through hole 7 and the second through hole 8. Slowly remove the tool. Under the elastic force of the first spring 14, the limiting block 16 and the fixing block 15 move in opposite directions, thereby fixing the top plate 6 to the bracket 4, and thus fixing the valve body 1 to the actuator 3. The operation is convenient and reduces the workload of workers.

[0027] When disassembly is required, remove the movable column 27 from the second locking block 18. Then, push the two movable plates 26 by hand to move them opposite each other along the fifth groove 25. The movable plates 26 drive the movable block 22 to move, so that the movable block 22 moves out of the fourth groove 24 and moves along the second groove 21. The movable block 22 squeezes the second spring 20, so that the second spring 20 generates elastic force, moves the first locking block 17, and the first locking block 17 drives the rectangular block 19 and the movable block 22 to move along the third groove 23. The second spring 20 drives the movable block 22 to reset through elastic force. Finally, use a tool to squeeze the X-shaped plate 11 and repeat the above operation to remove the X-shaped plate 11 from the first through hole 7 and the second through hole 8.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
