Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold fixing devices, and in particular to a cross-flow fan mold fixing device for preventing displacement. Background Technology
[0002] The anti-displacement cross-flow fan mold fixing device is a high-precision mechanical system that can precisely constrain the cross-flow fan injection mold, eliminating or suppressing the slight displacement caused by changes in injection pressure and temperature during production. It achieves stable fixing through positioning reference components and clamping mechanisms. It is used because the cross-flow fan structure has high precision requirements, and mold displacement can lead to product defects. During the injection molding process, the mold faces multiple displacement risks, and traditional fixing devices cannot meet the precision requirements. It can ensure product precision, reduce noise, improve production stability, and reduce costs and losses.
[0003] The existing anti-displacement cross-flow fan mold fixing device works by using a synergistic mechanism of precise positioning, stable constraint, and dynamic compensation. First, it uses precision guide pillars and positioning pins to achieve initial precise alignment of the mold. Then, it uses hydraulic or pneumatic clamps to apply continuous and uniform constraint force for static clamping. At the same time, it dynamically suppresses or cancels out the slight displacement caused by injection pressure impact and temperature changes during the injection process through elastic pre-tightening components, thermal compensation shims, or sensor feedback driven fine-tuning mechanisms. This ensures that the mold cavity and core are always precisely aligned, achieving the anti-displacement effect.
[0004] However, existing cross-flow fan mold fixing devices for preventing displacement still have significant limitations in practical applications. When the equipment performs mold opening and closing actions, the instantaneous start and stop of the mechanical transmission components will generate high-frequency vibrations. These vibrations are transmitted to the mold through the base, which can easily cause slight slippage on the contact surface between the mold and the fixing device. Although the device has initial positioning and static clamping capabilities, traditional rigid clamping structures are prone to stress rebound when faced with the periodic impact during mold opening and closing, causing the mold to shift laterally or axially. Although such displacements are minor, they can accumulate and affect the dimensional accuracy of the cross-flow fan blades, resulting in uneven blade thickness and center of gravity shift. This not only reduces the product qualification rate but also increases the cost of subsequent dynamic balancing correction, seriously restricting the efficient and stable operation of the device.

[0027] Reference Figure 1 - Figure 4This utility model provides an embodiment of a cross-flow fan mold fixing device to prevent displacement, including a base 1. A storage box 4 is fixedly connected to the outer wall of the base 1 for placing other items for easy access by the operator. A control component is provided on one side of the base 1 to control the data inside the device and control the internal mechanical movement. Multiple positioning rods 5 are fixedly connected inside the base 1 to provide positioning for the mold 7 to be fastened, preventing large displacement during the fastening process that would cause it to not be properly fastened. Multiple fixing plates 6 are fixedly connected to the inner wall of the base 1 to connect the mold 7 and fix it inside the device. The supply point has a mold 7 slidably connected to one side of each fixed plate 6, which is the main body for producing cross-flow fans. Each fixed plate 6 has multiple support components inside, which cooperate with the fixed plate 6 to support the mold 7 on one side of the fixed plate 6. Each mold 7 has connecting strips 11 fixedly connected to both sides to connect the mold 7 to the fixed plate 6 to prevent it from shaking. Each connecting strip 11 has multiple fixing grooves 12 inside to accommodate fixing columns 16 to connect the extrusion plate 15 to the mold 7. Each fixed plate 6 has multiple fixing components on its outer wall, which cooperate with the fixed plate 6 to fix the mold 7 on one side of the fixed plate 6. Each fixing component includes a connecting plate 13, a threaded post 14, a pressing plate 15, and a pressing nut 17. One side of the connecting plate 13 is slidably connected to the outer wall of the fixing plate 6, raising the pressing plate 15 to fit against the surface of the connecting strip 11. One end of the threaded post 14 is fixedly connected to one side of the connecting plate 13, and the pressing nut 17 is connected to clamp the pressing plate 15 to the connecting plate 13. The inner wall of the pressing plate 15 is slidably connected to the outer wall of the threaded post 14, cooperating with the fixing post 16 to press the connecting strip 11 and fix the mold 7 to the surface of the fixing plate 6. A fixing post 16 is fixedly connected to one side of the pressing plate 15, cooperating with the pressing plate 15 to restrict the movement of the connecting strip 11. The inner wall of the pressing nut 17 is threadedly connected to the outer wall of the threaded post 14, pressing the connecting strip 11 and the connecting plate 6 by the pressing plate 15. 13. The surface is pressed to fix the mold 7 on the fixed plate 6. Each support component includes a connecting block 8, a lifting plate 9 and a support plate 10. The outer wall of the connecting block 8 is slidably connected to the inside of the fixed plate 6. The lifting plate 9 and the support plate 10 are connected to one side of the fixed plate 6. One side of the lifting plate 9 and the support plate 10 are fixedly connected to one side of the connecting block 8. They cooperate with the support plate 10 to support the mold 7 and prevent it from shifting during the fastening process. The top of the support plate 10 is fixedly connected to the bottom of the lifting plate 9. The operation component includes a display screen 2 and multiple buttons 3. One side of the display screen 2 is electrically connected to the outer wall of the base 1. One end of each button 3 is electrically connected to the outer wall of the base 1. The control component consists of the display screen 2 and the buttons 3, which achieves the effect of operating the internal data of the equipment. Specifically, during the installation of mold 7, the mold 7 is first lifted using hoisting equipment and moved to the installation position inside the base 1. Then, mold 7 is lowered until its bottom is in contact with the surface of the lifting plate 9. Next, the operator holds the compression nut 17 with both hands and rotates it clockwise. As the threads are gradually tightened, the compression plates 15 on both sides begin to apply pressure to the connecting plates 13 and connecting strips 11 on both sides of mold 7. Under the action of pressure, the fixing post 16 on the inner side of the compression plate 15 slides into the fixing groove 12 inside the connecting strip 11. Through this installation operation, mold 7 is fixed on the fixing plate 6. It can remain stable even when the equipment vibrates during operation or is subjected to high pressure impact during injection molding, effectively preventing displacement problems caused by vibration and providing a solid guarantee for the high-quality molding of the cross-flow fan.
[0028] Reference Figure 4 - Figure 6 Each fixed plate 6 has multiple sliding grooves 18 on its outer wall to accommodate limiting blocks 19 for easy left and right movement. Each connecting plate 13 has a limiting block 19 fixedly connected to one side, which cooperates with the sliding grooves 18 to limit the movement range of the connecting plate 13. The outer wall of each limiting block 19 is slidably connected inside the sliding groove 18. Each fixed plate 6 has multiple storage slots 20 and multiple limiting slots 21 on one side. Each storage slot 20 is located at the bottom of the sliding groove 18 to accommodate fixing pins 22 for easy up and down movement to control the unlocking and fixing of the connecting block 8. Each limiting slot 21 is located inside the storage slot 20 to accommodate limiting posts 23. The movement range of the fixing pin 22 is limited. Each fixing plate 6 has a fixing pin 22 slidably connected inside. The connecting block 8 is fixed inside the fixing plate 6 by its own weight. Each fixing pin 22 has a limit post 23 fixedly connected on both sides. It works with the limit groove 21 to limit the movement range of the fixing pin 22. Each fixing pin 22 has a lever 24 fixedly connected on one side. It drives the fixing pin 22 to move up and down to control the unlocking and fixing of the connecting block 8. The outer wall of each limit post 23 is slidably connected inside the limit groove 21. The outer wall of each fixing pin 22 is slidably connected inside the storage groove 20. The bottom end of each fixing pin 22 is slidably connected inside the connecting block 8.
[0029] Specifically, when it is necessary to replace the lifting plate 9, first remove the mold 7 and place it aside. Then, the operator holds the lever 24 and pulls it upward with a little force. At this time, the fixing pin 22 connected to it rises simultaneously and disengages from the inside of the connecting block 8, so that the lifting plate 9 is released and can be easily removed. Next, take out the new lifting plate 9, align it with the installation position of the fixing plate 6, and insert the limiting strip 25 at the bottom of the lifting plate 9 into the corresponding groove inside the fixing plate 6, so that the limiting strip 25 fits tightly with the groove wall. Finally, release the lever 24 so that the fixing pin 22 falls vertically under the action of gravity and locks into the inside of the connecting block 8, thus laying a solid foundation for the subsequent installation of the mold 7.
[0030] Working principle: In the process of using the anti-displacement cross-flow fan mold fixing device, first lift the mold 7 and move it into the base 1. Then, align its bottom with the surface of the lifting plate 9. Next, hold the compression nut 17 and rotate it to make the compression plate 15 compress the connecting plate 13 and the connecting strip 11, so that the fixing post 16 is inserted into the fixing groove 12 inside the connecting strip 11, thereby fixing the mold 7 on the fixing plate 6. This prevents the mold 7 from shifting due to vibration during use. When it is necessary to replace the mold 7, first hold the compression nut 17 and turn it out from the outer wall of the threaded post 14 to make the compression plate 15 and the connecting plate 13 and connecting strip 11 fit together. 1. Release the lever to unlock the fixing post 16, then grasp the extrusion plate 15 and pull it outward to disengage the fixing post 16 from the inside of the connecting bar 11. At the same time, disengage the extrusion plate 15 from the outside of the threaded post 14, thereby unlocking the mold 7 and lifting it out of the base 1. Then, reinstall the new mold 7 into the base 1. When it is necessary to replace the lifting plate 9, first grasp the lever 24 and pull it upward to disengage the fixing pin 22 from the inside of the connecting block 8, unlocking the lifting plate 9. Then, take out the new lifting plate 9 and insert the limiting strip 25 at its bottom end into the fixing plate 6. Then, release the lever 24 to make the fixing pin 22 fall and get stuck inside the connecting block 8.
