Description

Technical Field

[0001] This application relates to the field of core casting technology, and more particularly to an automatic brushing device for core casting. Background Technology

[0002] In the casting process, a core (also known as a sand core) is a core made of molding sand (or other refractory materials) used to form internal cavities or complex structures in a casting. Its function is to occupy the space that the molten metal cannot fill during casting. After the casting cools, it is removed, thus forming complex structures such as internal cavities, channels, and grooves in the casting. After the core is formed, its surface needs to be coated to improve its smoothness and prevent sand from sticking to the casting.

[0003] The published patent document CN221336532U discloses a tooling device for brushing mud cores, relating to the field of mud core processing technology. This utility model includes a processing table with a brushing mechanism on one side, comprising a fixing box. In use, the mud core is placed on a rotating seat, and the mud core is fixed by a fitting block. Then, a brush block coated with paint is moved towards the mud core until one side of the brush block is in contact with the surface of the mud core. After contact, a lifting rod is moved downwards to allow a connecting block to enter the connecting fixing groove, thereby fixing the pull-out plate and the brush block. Finally, the rotating motor is started, and its output drives the rotating seat to rotate, causing the mud core to rotate on one side of the brush block, thus brushing the surface of the mud core. This brushing method not only has a fast brushing speed but also ensures the uniformity of the paint on the mud core after brushing.

[0004] When using the above devices, only the sides of the core can be brushed, making it difficult to evenly brush the bottom and top of the core. The brushing effect is not comprehensive enough, and there are dead corners after brushing, which may affect the subsequent casting production. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides an automatic brushing device for core casting, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: an automatic brushing device for core casting, comprising two sets of bases, each set of bases having a column at its top, a support platform and a horizontal plate between the two sets of bases, and a top brushing mechanism between the two sets of columns. The top brushing mechanism includes a fixed frame, a brushing motor above the fixed frame, and a rotating block fixedly connected to the bottom output end of the brushing motor through the fixed frame. The rotating block has an internal mounting groove, and a top brush is slidably connected inside the mounting groove. Both sides of the top coating plate are provided with side coating mechanisms. The directions of the two sets of side coating mechanisms are perpendicular to each other with the top coating. A mounting groove is opened in the middle of the support platform. Three sets of clamping mechanisms are provided on the top of the support platform. The three sets of clamping mechanisms are radially distributed around the mounting groove. A bottom coating mechanism is provided inside the mounting groove. The bottom coating mechanism includes a support plate. A drive motor is provided at the bottom of the support plate. The output end of the drive motor passes through the support plate and is fixedly installed on a rotating plate. A bottom coating is provided on the top of the rotating plate.

[0007] By adopting the above technical solution and setting a base, during use, the clay core to be coated is placed on top of the rotating disk, and its exterior is clamped and fixed using three sets of clamping mechanisms. Then, the top brushing mechanism is activated, and the brushing motor drives the rotating block to rotate. The top brush located below the rotating block brushes the top of the clay core, while the side brushing mechanisms on both sides move circumferentially around the outside of the clay core, brushing the side walls of the clay core. The drive motor at the bottom drives the rotating disk to move slowly at an angle inside the support plate, at which time the bottom brush brushes the bottom of the clay core. In this way, during use, the top brushing mechanism, the side brushing mechanism, and the bottom brushing mechanism work together to quickly and thoroughly brush the outer wall of the clay core, reduce brushing dead corners, realize the full automation of the clay core brushing process, significantly reduce manual operation, and effectively reduce the labor intensity of operators.

[0008] As a preferred technical solution of this application, the side coating mechanism includes a connecting frame, an adjustment groove is provided inside the connecting frame, a side coating brush is slidably connected inside the adjustment groove, and an adjustment screw is rotatably connected inside the adjustment groove. The adjustment screw is threadedly connected to one end of the side coating brush.

[0009] By adopting the above technical solution and setting a side brushing mechanism, the distance between the side brush and the core can be adjusted by rotating the adjusting screw before brushing the core. This ensures the adhesion between the side brush and the outer wall of the core, reduces gaps, and improves the brushing effect.

[0010] As a preferred technical solution of this application, the clamping mechanism includes a fixing plate, and a fixed electric push rod is provided on the side of the fixing plate near the mounting groove. The telescopic end of the fixed electric push rod is provided with a clamping block.

[0011] By adopting the above technical solution and setting a fixed plate, the fixed electric push rod can drive the clamping block to move to one side of the core during use. The three sets of clamping blocks can better clamp the outer wall of the core and prevent shaking and displacement during brushing.

[0012] As a preferred technical solution of this application, both sets of columns are provided with a movable groove inside, and both sets of movable grooves are provided with an adjusting hydraulic rod inside. The top of the adjusting hydraulic rod is provided with a movable plate that is slidably connected to the movable groove, and one side of the movable plate is fixedly connected to the fixed frame.

[0013] By adopting the above technical solution, by setting up a moving groove, the hydraulic rod can be adjusted to drive the moving plate to move inside the moving groove, thereby adjusting the height of the top brushing mechanism, ensuring the gap between the top brush and the top of the core, and applying a certain force to the top of the core, which cooperates with the clamping mechanism set at the bottom, further ensuring the stability of the core during brushing and enhancing the brushing effect.

[0014] As a preferred technical solution of this application, the top of the top coating brush is provided with a slider, the inner sides of the mounting groove are provided with connecting grooves, and the slider is provided with connecting blocks that are slidably connected to the inside of the connecting grooves on both sides.

[0015] By adopting the above technical solution and setting the mounting groove, the top coating brush can move up and down inside the mounting groove, which improves the contact effect between the top coating brush and the top of the core. At the same time, it can provide a certain buffer space between the top coating brush and the core, ensuring that the top coating brush remains stable when brushing the core.

[0016] As a preferred technical solution of this application, the top of the slider is provided with multiple sets of springs, and the top of the springs abuts against the rotating block.

[0017] By adopting the above technical solution and setting a spring, downward pressure can be applied to the top coating brush to ensure the stability of the connection between the top coating brush and the top of the core, and improve the uniformity of the coating.

[0018] As a preferred technical solution of this application, a stabilizing block is fixedly connected to the top of both sets of side coatings, and the stabilizing block is slidably connected to the top of the connecting frame.

[0019] By adopting the above technical solution and setting a stabilizing block, stability can be improved when adjusting the position of the side coating during use. At the same time, the side coating is limited to ensure stability during brushing and prevent tilting of the side coating.

[0020] As a preferred technical solution of this application, the side of each of the three sets of clamping blocks near the mounting groove is set as an arc surface.

[0021] By adopting the above technical solution, and by setting one side of the clamping block to be an arc surface, the clamping block can be effectively fixed to the outer wall of the core, and can also be fixed when the outer wall of the core has an irregular shape, thus improving the stability during brushing.

[0022] The beneficial effects of this application are: 1. By setting a base, during use, the clay core to be coated is placed on top of the rotating disk, and its exterior is clamped and fixed using three sets of clamping mechanisms. Then, the top brushing mechanism is activated, and the brushing motor drives the rotating block to rotate. The top brush located below the rotating block brushes the top of the clay core. At the same time, the side brushing mechanisms move circumferentially around the outside of the clay core with the rotating block, brushing the side walls of the clay core. The drive motor at the bottom drives the rotating disk to move slowly at an angle inside the support plate. At this time, the bottom brush brushes the bottom of the clay core. In this way, during use, the top brushing mechanism, the side brushing mechanism, and the bottom brushing mechanism work together to quickly and thoroughly brush the outer wall of the clay core, reduce brushing dead corners, realize the full automation of the clay core brushing process, significantly reduce manual operation, and effectively reduce the labor intensity of operators.

[0023] 2. By setting up a side brushing mechanism, the distance between the side brush and the core can be adjusted by rotating the adjusting screw before brushing the core. This ensures the adhesion between the side brush and the outer wall of the core, reduces gaps, and improves the brushing effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figure 1-3 An automatic coating device for core casting includes two sets of bases 1, each with a column 102 on its top. A support platform 101 and a horizontal plate 104 are provided between the two sets of bases 1. A top coating mechanism 2 is provided between the two sets of columns 102. The top coating mechanism 2 includes a fixed frame 201, a coating motor 202 is provided above the fixed frame 201, and a rotating block 203 is fixedly connected to the bottom output end of the coating motor 202 through the fixed frame 201. A mounting groove 204 is provided inside the rotating block 203, and a top coating brush 205 is slidably connected inside the mounting groove 204. Side coating mechanisms 3 are provided on both sides of the rotating block 203, and the directions of the two sets of side coating mechanisms 3 are perpendicular to the top coating brush 205. The support platform 101 has a mounting groove 105 in the middle. The top of the support platform 101 is provided with three sets of clamping mechanisms 5, which are radially distributed around the mounting groove 105. The mounting groove 105 is provided with a bottom brushing mechanism 4. The bottom brushing mechanism 4 includes a support plate 401. The bottom of the support plate 401 is provided with a drive motor 403. The output end of the drive motor 403 passes through the support plate 401 and is fixedly installed with a rotating plate 402. The top of the rotating plate 402 is provided with a bottom brush 404. The clamping mechanism 5 includes a fixing plate 501. The side of the fixing plate 501 near the mounting groove 105 is provided with a fixed electric push rod 502. The telescopic end of the fixed electric push rod 502 is provided with a clamping block 503.

[0028] By setting the base 1, during use, the clay core to be coated is placed on top of the rotating disk 402, and its exterior is clamped and fixed using three sets of clamping mechanisms 5. Then, the top brushing mechanism 2 is activated, and the brushing motor 202 drives the rotating block 203 to rotate. The top brush 205 located below the rotating block 203 brushes the top of the clay core. At the same time, the side brushing mechanisms 3 on both sides move circumferentially around the outside of the clay core, following the rotating block 203, and brush the side walls of the clay core. The drive motor 403 at the bottom drives the rotating disk 402 to move slowly at an angle inside the support disk 401. The bottom coating 404 will coat the bottom of the core. In use, the top coating mechanism 2, the side coating mechanism 3, and the bottom coating mechanism 4 work together to quickly and thoroughly coat the outer wall of the core, reducing blind spots and automating the entire core coating process. This significantly reduces manual operation and effectively lowers the labor intensity of operators. By setting a fixing plate 501, the fixed electric push rod 502 can drive the clamping block 503 to move to one side of the core during use. The three sets of clamping blocks 503 can better hold the outer wall of the core and prevent shaking or displacement during coating.

[0029] Reference Figure 3-5 The side coating mechanism 3 includes a connecting frame 301, an adjusting groove 303 inside the connecting frame 301, a side coating brush 302 slidably connected inside the adjusting groove 303, and an adjusting screw 304 rotatably connected inside the adjusting groove 303. The adjusting screw 304 is threadedly connected to one end of the side coating brush 302. Each of the two sets of columns 102 has a moving groove 103 inside, and each of the two sets of moving grooves 103 has an adjusting hydraulic rod 6 inside. The top of the adjusting hydraulic rod 6 has a moving plate 602 slidably connected inside the moving groove 103, and one side of the moving plate 602 is fixedly connected to the fixed frame 201. The top of the slider 206 has multiple sets of springs 207, and the top of the springs 207 abuts against the rotating block 203. By setting the side coating mechanism 3, the side coating can be applied to the core before... The distance between the side coating 302 and the core is adjusted by rotating the adjusting screw 304, which ensures the fit between the side coating 302 and the outer wall of the core, reduces gaps, and improves the coating effect. By setting the moving groove 103, the adjusting hydraulic rod 601 can drive the moving plate 602 to move inside the moving groove 103, thereby adjusting the height of the top coating mechanism 2, ensuring the gap between the top coating 205 and the top of the core, and applying a certain force to the top of the core, which cooperates with the clamping mechanism 5 set at the bottom to further ensure the stability of the core during coating and enhance the coating effect. By setting the spring 207, downward pressure can be applied to the top coating 205 to ensure the stability of the connection between the top coating 205 and the top of the core and improve the uniformity of the coating.

[0030] Reference Figure 3-5 The top of the top coating brush 205 is equipped with a slider 206. Connecting grooves 209 are provided on both sides of the mounting groove 204. Connecting blocks 208 are slidably connected to the connecting grooves 209 on both sides of the slider 206. By providing the mounting grooves 204, the top coating brush 205 can move up and down within the mounting grooves 204, improving the contact effect between the top coating brush 205 and the top of the core. It also provides a certain buffer space between the top coating brush 205 and the core, ensuring that the top coating brush 205 remains stable when brushing the core. Stabilizing blocks 306 are fixedly connected to the tops of both sets of side coating brushes 302. The stabilizing block 306 is slidably connected to the top of the connecting frame 301. By setting the stabilizing block 306, stability can be improved when adjusting the position of the side coating 302 during use. At the same time, the side coating 302 is limited to ensure stability during brushing and prevent the side coating 302 from tilting. The three sets of clamping blocks 503 are all set with curved surfaces on the side near the mounting groove 105. By setting one side of the clamping block 503 to be curved, the fixing effect of the clamping block 503 on the outer wall of the core can be ensured. Even when the outer wall of the core has an irregular shape, it can be fixed, improving the stability during brushing.

[0031] Working principle: By setting the base 1, during use, the clay core to be coated is placed on top of the rotating disk 402, and its exterior is clamped and fixed using three sets of clamping mechanisms 5. Then, the top brushing mechanism 2 is activated, and the brushing motor 202 drives the rotating block 203 to rotate. The top brush 205 located below the rotating block 203 brushes the top of the clay core. At the same time, the side brushing mechanisms 3 follow the rotating block 203 and move circumferentially around the outside of the clay core to brush the side walls of the clay core. The drive motor 403 at the bottom drives the rotating disk 402 to move slowly at an angle inside the support disk 401. At this time, the bottom coating... The 404 brush will coat the bottom of the clay core. In use, the top brushing mechanism 2, the side brushing mechanism 3, and the bottom brushing mechanism 4 work together to quickly and thoroughly coat the outer wall of the clay core, reducing brushing dead corners and automating the entire clay core brushing process. This significantly reduces manual operation and effectively lowers the labor intensity of operators. By setting up the side brushing mechanism 3, the distance between the side brush 302 and the clay core can be adjusted by rotating the adjusting screw 304 before brushing the clay core. This ensures the fit between the side brush 302 and the outer wall of the clay core, reduces gaps, and improves the brushing effect. In this system, by setting a fixed plate 501, the fixed electric push rod 502 can drive the clamping block 503 to move to one side of the core during use. The three sets of clamping blocks 503 can better clamp the outer wall of the core, preventing shaking and displacement during brushing. By setting a moving groove 103, the hydraulic rod 601 can drive the moving plate 602 to move inside the moving groove 103, thereby adjusting the height of the top brushing mechanism 2, ensuring the gap between the top brush 205 and the top of the core, and applying a certain force to the top of the core, which cooperates with the clamping mechanism 5 set at the bottom to further ensure the stability of the core during brushing and enhance the brushing effect. Meanwhile, by setting the mounting groove 204, the top coating brush 205 can move up and down inside the mounting groove 204, improving the contact effect between the top coating brush 205 and the top of the core, and providing a certain buffer space between the top coating brush 205 and the core, ensuring that the top coating brush 205 remains stable when brushing the core. In addition, by setting the spring 207, downward pressure can be applied to the top coating brush 205 to ensure the stability of the connection between the top coating brush 205 and the top of the core, and improve the uniformity of brushing. By setting the stabilizing block 306, stability can be improved when adjusting the position of the side coating brush 302 during use, and the side coating brush 302 can be limited to ensure stability during brushing and prevent the side coating brush 302 from tilting. By setting one side of the clamping block 503 to be curved, the clamping block 503 can be fixed to the outer wall of the core, and can be fixed even when the outer wall of the core has an irregular shape, thus improving the stability during brushing.
