Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5As shown in the embodiment of the present invention, an internal high-pressure forming mold changing and conveying device includes a conveying device body 1; an outer shell 11 is fixedly connected to the side wall of the conveying device body 1; a rotating roller 12 is provided on the inner side wall of the outer shell 11; the rotating roller 12 penetrates the wall of the outer shell 11 and is rotatably connected to it; a plurality of brush bristles 13 are uniformly fixedly connected to the side wall of the rotating roller 12; a pair of rotating rollers 14 are provided on the inner side wall of the outer shell 11; the rotating rollers 14 are symmetrically arranged on both sides of the outer shell 11 and The structures are identical; the second rotating roller 14 penetrates the wall of the outer shell 11 and is rotatably connected to it; multiple bristles 15 are evenly fixed to the side wall of the second rotating roller 14; a driving wheel 16 is fixed to the end of the first rotating roller 12; a driven wheel 17 is fixed to the end of the second rotating roller 14; a drive motor 18 is provided on the side wall of the outer shell 11; the output end of the drive motor 18 is fixedly connected to the driving wheel 16; a transmission belt 19 is rotatably connected between the driving wheel 16 and the driven wheel 17; in use, it is conveyed... When the device body 1 is conveying and changing the internal high-pressure forming mold, the drive motor 18 is started. The output end of the drive motor 18 drives the fixed drive wheel 16 to rotate. The drive wheel 16 drives the driven wheels 17 symmetrically arranged on both sides to rotate synchronously through the transmission belt 19. This, in turn, drives the rotating roller 14 fixed to the driven wheel 17 and the rotating roller 12 fixed to the drive wheel 16 to rotate in the same direction. The brush 13 on the side wall of the rotating roller 12 and the brush 15 on the side wall of the rotating roller 14 rotate at high speed with the rotating roller. When the mold is in the conveying device body When moving on body 1, brush bristles 13 and 15 clean the top of the mold, removing oil, metal debris and impurities from the mold surface. During this process, the synchronous operation of roller 12 and roller 214 is achieved through the linkage design of drive wheel 16 and driven wheel 17. Bristles 13 and 15 work together to form a large-area cleaning, ensuring that there are no dead corners in the top of the mold. A single drive motor 18 drives multiple sets of rollers, reducing equipment energy consumption, improving cleaning efficiency, and adapting to the cleaning needs during mold changing.

[0023] like Figures 1-5As shown, an electric push rod 2 is fixedly connected to the side wall of the outer casing 11; the electric push rod 2 is fixedly connected to the drive motor 18; multiple guide holes 21 are evenly distributed on the side wall of the outer casing 11; the first rotating roller 12 and the second rotating roller 14 are slidably fitted with the guide holes 21; multiple guide rails 22 are fixedly connected to the inner side wall of the outer casing 11; the guide rails 22 are evenly distributed on the inner side wall of the outer casing 11 and have the same structure; sliders 23 are slidably connected to the inner side wall of the guide rails 22; connecting plates 24 are fixedly connected between the sliders 23; the first rotating roller 12, the second rotating roller 14 and the connecting plate 24 are rotatably connected; in use, according to the size and specifications of the mold to be cleaned, the electric push rod 2 fixedly connected to the side wall of the outer casing 11 is activated, and the electric push rod 2 extends and retracts, driving the fixed drive motor 18 to move horizontally. Since both roller 12 and roller 24 are rotatably connected to the connecting plate 24, and the connecting plate 24 is slidably engaged with the guide rail 22 on the inner side wall of the outer shell 11 via the slider 23, roller 12 and roller 24 slide synchronously along the guide hole 21 with the drive motor 18, thereby adjusting the height of roller 12 and roller 24 so that brush bristles 13 and brush bristles 25 can accurately fit the surface of molds of different heights. In this process, the height adjustment structure driven by the electric push rod 12 achieves adaptive adjustment of cleaning, adapting to the cleaning needs of high-pressure forming molds of different specifications, avoiding the problem of incomplete cleaning caused by differences in mold size. The cooperation between the guide rail 22 and the slider 23 ensures the stability of roller 12 and roller 24 during movement, and the guide hole 21 plays a limiting role, improving the adjustment accuracy.

[0024] like Figures 1-5As shown, a sleeve 3 is fixedly connected to the top of the outer casing 11; a pair of connecting pipes 31 are fixedly connected to the side wall of the sleeve 3 and penetrate its wall; the connecting pipes 31 are symmetrically arranged on both sides of the sleeve 3 and have the same structure; an air guide pipe 32 is fixedly connected to the end of the connecting pipe 31; the air guide pipe 32 penetrates the wall of the outer casing 11 and is fixedly connected to it; a drive motor 33 is fixedly connected to the inner side wall of the sleeve 3; a fan blade 34 is fixedly connected to the output end of the drive motor 33; a filter screen plate 35 is provided on the side wall of the sleeve 3; during use, while the first bristle 13 and the second bristle 15 are cleaning, the drive motor 33 on the inner side wall of the sleeve 3 is started, and the output end of the drive motor 33 drives the fan blade 34 to rotate at high speed. A negative pressure is created inside the sleeve 3. Outside air enters the sleeve 3 after being filtered by the filter screen 35 to remove dust and impurities. It is then introduced into the air guide pipe 32 through the symmetrical connecting pipes 31 on both sides of the sleeve 3. The air guide pipe 32 blows clean airflow into the cleaning area, blowing away the debris and dust washed off the mold surface. At the same time, it accelerates the evaporation of residual oil on the mold surface. In this process, air washing and brush washing work together. The airflow can quickly remove loose impurities, preventing the impurities from re-attaching after cleaning and improving the cleaning effect. The filter screen 35 can filter impurities in the incoming air and prevent external dust from contaminating the mold surface. The symmetrically arranged connecting pipes 31 and air guide pipe 32 ensure that the airflow evenly covers the cleaning area, enhancing the comprehensiveness of auxiliary cleaning.

[0025] like Figures 1-5 As shown, a magnetic block 4 is fixedly connected to the output end of the drive motor 33; a rotating rod 41 is rotatably connected to the top of the filter plate 35; a pair of cleaning brush plates 42 are fixedly connected to the side wall of the rotating rod 41; the cleaning brush plates 42 are symmetrically arranged on both sides of the rotating rod 41 and have the same structure; a magnetic block 43 is fixedly connected to the side wall of the cleaning brush plate 42; the magnetic block 4 and the magnetic block 43 are magnetically connected; in use, when the drive motor 33 starts, the magnetic block 4 fixedly connected to its output end rotates synchronously with the output shaft. Since the magnetic block 4 and the magnetic block 43 on the side wall of the cleaning brush plate 42 are magnetically connected, the magnetic field force generated by the rotation of the magnetic block 4 drives the magnetic block 43 and the cleaning brush plate 42. The brush plate 42 rotates around the rotating rod 41, which is rotatably connected to the top of the filter screen plate 35. This allows the cleaning brush plate 42 to make close contact with the surface of the filter screen plate 35 during rotation, brushing away dust and impurities adhering to the filter screen plate 35 and preventing clogging. During this process, the rotational power of the drive motor 33 is used to achieve synchronous operation of the cleaning brush plate 42, eliminating the need for an additional power source and simplifying the equipment structure. The magnetic connection design ensures the linkage stability between the cleaning brush plate 42 and the magnetic block 4. The rotational brushing of the cleaning brush plate 42 can promptly remove impurities from the surface of the filter screen plate 35, ensuring unobstructed airflow and maintaining the continuous cleaning operation of the air washing mechanism.

[0026] like Figures 1-5As shown, multiple casters 5 are evenly fixed to the side wall of the conveyor body 1; a pair of electric push rods 51 are fixed to the side wall of the conveyor body 1; the electric push rods 51 are symmetrically arranged on both sides of the conveyor body 1 and have the same structure; a fixing plate 52 is fixed to the end of the electric push rod 51; multiple anti-slip pads 53 are evenly fixed to the bottom of the fixing plate 52; in use, when the device needs to be moved, the electric push rods 51 are activated to retract, which drives the fixing plate 52 to rise, so that the anti-slip pads 53 at the bottom of the fixing plate 52 are lifted off the ground. At this time, the casters 5 on the side wall of the conveyor body 1 contact the ground, and the conveyor body 1 can be pushed to move through the ground. The caster wheel 5 allows for flexible movement, adapting to the mold-changing needs of different workstations. When the conveyor body 1 moves to the target position, the electric actuator 51 is activated to extend it, causing the fixed plate 52 to descend until the anti-slip pad 53 is tightly attached to the ground. The friction of the anti-slip pad 53 is used to fix the equipment. During this process, the caster wheel 5 is designed to facilitate the movement of the equipment and reduce the difficulty of equipment transfer during mold changing. The fixed plate 52 driven by the electric actuator 51 cooperates with the anti-slip pad 53 to quickly fix and unlock the equipment. The anti-slip pad 53 enhances the friction between the equipment and the ground, improves the stability of the equipment during the cleaning process, and avoids the decrease in cleaning accuracy caused by vibration.

[0027] like Figures 1-5 As shown, the bottom of the fixing plate 52 has a groove 6; a spring rod 61 is fixedly connected to the side wall of the groove 6; a pair of telescopic rods 62 are fixedly connected to the side wall of the fixing plate 52; the telescopic rods 62 are symmetrically arranged on both sides of the fixing plate 52 and have the same structure; a support plate 63 is fixedly connected to the end of the telescopic rod 62; a top rod 64 is hinged between the support plate 63 and the spring rod 61; in use, when the fixing plate 52 descends and contacts the ground, the support plate 63 contacts the ground first and receives the reaction force from the ground, and the reaction force is transmitted to the spring rod 61 through the top rod 64. The spring rod 61 retracts within the groove 6, acting as a buffer to reduce the impact on the ground when the fixed plate 52 descends. Simultaneously, the top rod 64 pushes the support plate 63 to expand to both sides along the telescopic rod 62, increasing the support area of ​​the support plate 63 and further enhancing the stability of the equipment. During this process, the buffer design of the spring rod 61 prevents damage to the ground when the equipment is fixed. The telescopic rod 62 and the top rod 64 work together to make the support area of ​​the support plate 63 adjustable, enhancing the stability of the equipment under different ground conditions, preventing the equipment from tilting, and ensuring the safety of the cleaning process.

[0028] like Figures 1-5As shown, the sleeve 3 has multiple locking blocks 7 hinged to its side wall; the locking blocks 7 are evenly distributed on the inner side wall of the sleeve 3 and have the same structure; the filter screen plate 35 has multiple slots 71 evenly opened on its side wall; in use, when it is necessary to replace or clean the filter screen plate 35, the locking blocks 7 are pulled outward to disengage the locking blocks 7 from the slots 71 on the side wall of the filter screen plate 35. At this time, the filter screen plate 35 loses its fixed constraint and can be quickly removed from the sleeve 3. During installation, the filter screen plate 35 is aligned with the installation position of the sleeve 3, the locking blocks 7 are released, and the locking blocks 7 are reset under the elastic action of their own internal torsion springs and locked into the slots 71, realizing the quick fixation of the filter screen plate 35. In this process, the snap-fit ​​design of the locking blocks 7 and the slots 71 simplifies the disassembly and assembly process of the filter screen plate 35, and the operation can be completed without tools, improving the equipment maintenance efficiency. The multiple evenly distributed locking blocks 7 ensure the firmness of the filter screen plate 35 after installation and prevent the filter screen plate 35 from loosening and shifting during air washing.

[0029] like Figures 1-5 As shown, a pull plate 8 is fixedly connected to the side wall of the locking block 7; the pull plate 8 is arc-shaped; multiple rubber pads 81 are evenly fixed to the side wall of the pull plate 8; during use, when disassembling or installing the filter screen 35, the operator can more easily apply force to turn the locking block 7 by holding the arc-shaped pull plate 8 fixed to the side wall of the locking block 7. The arc-shaped design fits the curvature of the hand, improving the ease of operation. The multiple rubber pads 81 on the side wall of the pull plate 8 increase the friction between the hand and the pull plate 8, preventing slippage during operation, and also playing a cushioning role to avoid hand injury from pressure. In this process, the arc-shaped pull plate 8 provides the operator with a convenient point of force application, reducing the difficulty of turning the locking block 7. The anti-slip and cushioning design of the rubber pads 81 improves the safety of operation and further optimizes the disassembly and assembly experience of the filter screen 35.

[0030] like Figures 1-5 As shown, the support plate 63 has multiple toothed blocks 9 evenly fixed to its bottom. In use, when the support plate 63 is unfolded and contacts the ground, the toothed blocks 9 evenly fixed to the bottom of the support plate 63 embed into the ground. Through the mechanical interlocking action of the toothed blocks 9 and the ground, the friction between the support plate 63 and the ground is enhanced, further preventing the equipment from sliding or shifting during the cleaning process. In this process, the mechanical interlocking design of the toothed blocks 9 has a more significant anti-slip effect than the anti-slip pad 53, adapting to complex ground environments. The multiple evenly distributed toothed blocks 9 ensure balanced support force, improve the stability of the equipment during high-frequency vibration cleaning, and ensure the continuity of cleaning operations.

[0031] like Figures 1-5As shown, a connecting rod 10 is fixedly connected to the side wall of the cleaning brush plate 42. In use, the connecting rod 10 fixedly connected to the side wall of the cleaning brush plate 42 can fix and connect the cleaning brushes on the side wall of the cleaning brush plate 42, and concentrate them together to prevent the cleaning brush plate 42 from deforming or breaking due to uneven force during high-speed rotation and brushing. At the same time, the connecting rod 10 can increase the cleaning effect of the cleaning brushes. In this process, the connecting rod 10 improves the concentration of the cleaning brushes on the side wall of the cleaning brush plate 42, increases the cleaning effect, and extends the service life.

[0032] During operation, when conveying and changing the inner high-pressure forming mold via the conveyor body 1, the drive motor 18 is started. The output end of the drive motor 18 drives the fixed drive wheel 16 to rotate. The drive wheel 16 drives the symmetrically arranged driven wheels 17 on both sides to rotate synchronously via the transmission belt 19. This, in turn, drives the rotating roller 14 fixed to the driven wheel 17 and the rotating roller 12 fixed to the drive wheel 16 to rotate in the same direction. The bristles 13 on the side wall of the rotating roller 12 and the bristles 15 on the side wall of the rotating roller 14 rotate at high speed with the rotating roller. When the mold moves on the conveyor body 1, the bristles 13 and 15 clean the top of the mold, removing oil stains, metal debris and impurities from the mold surface. In use, according to the size and specifications of the mold to be cleaned, the electric actuator fixed to the side wall of the outer shell 11 is started. Rod 12, the electric actuator 12, extends and retracts, driving the fixed drive motor 18 to move horizontally. Since both roller 12 and roller 24 are rotatably connected to the connecting plate 24, and the connecting plate 24 slides with the guide rail 22 on the inner wall of the outer casing 11 via the slider 23, roller 12 and roller 24 slide synchronously along the guide hole 21 with the drive motor 18, thereby adjusting the height of roller 12 and roller 214 so that brush bristles 13 and brush bristles 25 can accurately fit the surface of molds of different heights. During use, while brush bristles 13 and brush bristles 215 are cleaning, the drive motor 33 on the inner wall of the sleeve 3 is started. The output end of the drive motor 33 drives the fan blade 34 to rotate at high speed. The fan blade 34 forms a negative pressure inside the sleeve 3, and the outside air is filtered out by the filter screen 35. Dust and impurities enter the sleeve 3 and are then guided into the air guide pipe 32 through the symmetrical connecting pipes 31 on both sides of the sleeve 3. The air guide pipe 32 blows clean airflow into the cleaning area, blowing away the debris and dust washed off the mold surface, while accelerating the evaporation of residual oil on the mold surface. During use, when the drive motor 33 starts, the magnetic block 4 fixed to its output end rotates synchronously with the output shaft. Since the magnetic block 4 is magnetically connected to the magnetic block 43 on the side wall of the cleaning brush plate 42, the magnetic field force generated by the rotation of the magnetic block 4 drives the magnetic block 43 and the cleaning brush plate 42 to rotate around the rotating rod 41. The rotating rod 41 is rotatably connected to the top of the filter screen plate 35, so that the cleaning brush plate 42 is in close contact with the surface of the filter screen plate 35 during rotation, brushing away the dust and impurities attached to the filter screen plate 35 and preventing the filter screen from being damaged. When plate 35 is blocked, during use, when the equipment needs to be moved, the electric actuator 51 is activated to retract it, causing the fixed plate 52 to rise. This lifts the anti-slip pad 53 at the bottom of the fixed plate 52 off the ground. At this time, the casters 5 on the side wall of the conveyor body 1 contact the ground, allowing the conveyor body 1 to move flexibly via the casters 5, adapting to the mold changing needs of different workstations. After the conveyor body 1 moves to the target position, the electric actuator 51 is activated to extend it, causing the fixed plate 52 to descend until the anti-slip pad 53 is tightly attached to the ground. The friction of the anti-slip pad 53 is used to fix the equipment. During use, when the fixed plate 52 descends and contacts the ground, the support plate 63 first contacts the ground and receives the reaction force from the ground. The reaction force is transmitted to the spring rod 61 through the push rod 64.Spring rod 61 retracts within groove 6, acting as a buffer to reduce the impact on the ground when fixed plate 52 descends. Simultaneously, top rod 64 pushes support plate 63 to expand laterally along telescopic rod 62, increasing the support area of ​​support plate 63 and further enhancing the stability of the equipment. During use, when the filter screen 35 needs replacement or cleaning, the locking block 7 is pulled outwards to disengage from the slot 71 on the side wall of the filter screen 35. At this point, the filter screen 35 loses its fixed constraint and can be quickly removed from sleeve 3. During installation, align the filter screen 35 with the installation position on sleeve 3, release the locking block 7, and the locking block 7 resets under the elastic action of its internal torsion spring and engages with the slot 71, achieving rapid fixation of the filter screen 35. During use, when disassembling or installing the filter screen 35, the operator can more easily remove it by holding the arc-shaped pull plate 8 fixed to the side wall of the locking block 7. The lever 7 is easily operated with its curved design conforming to the hand's grip, enhancing ease of operation. Multiple rubber pads 81 on the side wall of the pull plate 8 increase friction between the hand and the plate, preventing slippage and providing cushioning to avoid hand injuries. During use, when the support plate 63 unfolds and contacts the ground, the evenly fixed teeth 9 at the bottom of the support plate 63 embed into the ground. The mechanical engagement of the teeth 9 with the ground enhances friction between the support plate 63 and the ground, further preventing slippage or displacement of the equipment during cleaning. During use, the connecting rod 10 fixed to the side wall of the cleaning brush plate 42 securely connects the cleaning brushes on the side wall of the cleaning brush plate 42, concentrating them together to prevent deformation or breakage due to uneven force during high-speed rotation. Simultaneously, the connecting rod 10 enhances the cleaning effect of the cleaning brushes.
