[0002] Aluminum alloy casting molds play an indispensable role in modern manufacturing, and are widely used in many fields such as automotive, aerospace, and machinery manufacturing. These molds are usually made of high-strength alloy materials to ensure they can withstand the high temperature and high pressure environment during the casting process.

[0003] When finishing cylindrical aluminum alloy casting molds, removing burrs and residual material is a crucial step in ensuring finished product quality. However, due to the continuity and curvature of the cylindrical surface, the finishing requirements for cylindrical molds vary at different positions and angles. Most existing finishing equipment lacks the flexibility to adjust angles, making it unable to adapt to these changing needs. Micro-dust and debris generated during the finishing process easily scatter on the worktable and in the surrounding environment, resulting in a cluttered work area, increasing the difficulty for operators, and potentially affecting finishing accuracy.

[0004] The purpose of this invention is to solve the problems of inconvenient angle adjustment and inconvenient cleaning of dust and debris generated during the trimming process of cylindrical aluminum alloy casting molds. Utility Model Content

[0028] 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.

[0029] like Figures 1 to 5As shown, this utility model proposes a grinding table, including a workbench 1. A limiting mechanism 2 is installed on the workbench 1. The limiting mechanism 2 includes a rotating mechanism 21, which includes a base 212. A bottom frame 211 is rotatably connected to the base 212. A support mechanism 22 is installed inside the bottom frame 211, with both sides of the support mechanism 22 rotatably connected to the side walls of the bottom frame 211. The workbench 1 has a dust suction port 11, and a dust suction mechanism 3 is installed inside the workbench 1 to suck up dust from the surface of the workbench 1 through the dust suction port 11. The limiting mechanism 2 installed on the workbench 1 is mainly used to fix the cylindrical mold to be repaired. Specifically, the rotating mechanism 21 serves as the basic part of the entire limiting mechanism 2, and the base 212 is fixedly connected to the workbench 1, providing stable support. The base frame 211 is mounted on the base 212 via a rotatable connection, allowing it to rotate 360 ​​degrees around the central axis of the base. This enables the operator to adjust the mold angle as needed to accommodate different finishing requirements. The support mechanism 22, installed within the base frame 211, is rotatably connected to the side walls of the base frame on both sides. This means the support mechanism can rotate not only horizontally but also tilt within a certain range vertically. This multi-dimensional adjustment capability provides more flexible operating space for the finishing tool, ensuring that the operator can treat the mold surface at the optimal angle. The dust collection mechanism 3 sucks in and collects debris and dust through the suction port 11. This design not only maintains a clean and safe working environment but also extends the equipment's lifespan and improves finishing quality and efficiency.

[0030] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a bearing 213 is provided between the base 212 and the bottom frame 211. The inner ring of the bearing 213 is fixedly connected to the bottom frame 211, and the outer ring of the bearing 213 is fixedly connected to the base 212. A connecting block 214 is installed on the top surface of the base 212, and a sleeve 215 is fitted over the connecting block 214. The sleeve 215 is threadedly connected to the connecting block 214, and a rod 216 is installed on one side of the sleeve 215. By rotating the sleeve 215 to push it upward and press against the bottom frame 211, a locking function can be provided during the trimming process to prevent unnecessary movement of the bottom frame 211 during the trimming process, thereby ensuring the stability of the mold throughout the trimming process and improving the trimming accuracy. The threaded connection design allows the operator to simply rotate the sleeve 215 to complete the height adjustment and limit locking without complicated tools or steps. The presence of the bearing 213 allows the bottom frame 211 to rotate smoothly on the base 212, reducing direct friction between the two.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the bottom frame 211 includes a bottom plate 2111, a first side plate 2112 is installed on one side of the top surface of the bottom plate 2111, and a second side plate 2113 is installed on the other side of the top surface of the bottom plate 2111. The first side plate 2112 has a first through hole 2115, and the second side plate 2113 has a second through hole 2116. The support mechanism 22 includes a frame 221. A connecting shaft 218 is sleeved in the first through hole 2115. The connecting shaft 218 is rotatably connected to the first through hole 2115 and is fixedly connected to the first side plate 2112. A rotating shaft 223 is sleeved in the second through hole 2116. The rotating shaft 223 is rotatably connected to the second through hole 2116 and is fixedly connected to the second side plate 2113. A worm gear 217 is mounted on one side of the first side plate 2112, and a gear is mounted on one side of the connecting shaft 218. The worm gear 217 meshes with the gear. The frame 221 supports the cylindrical mold to be trimmed, ensuring its stability during the trimming process. By rotating the worm gear 217, the gear is driven to rotate, which in turn causes the connecting shaft 218 to rotate. Since the connecting shaft 218 is fixedly connected to the frame 221, the frame 221 will tilt as the connecting shaft 218 rotates. The meshing of the worm gear 217 and the gear not only achieves precise angle adjustment but also has a self-locking characteristic, preventing angle changes caused by external forces.

[0032] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first side plate 2112 has a first arc groove 2114, and a first positioning rod 219 is fitted inside the first arc groove 2114. The first positioning rod 219 is slidably connected to the first arc groove 2114. A second threaded hole 224 is formed on one side of the frame 221, and the second threaded hole 224 is threadedly connected to the first positioning rod 219. The second side plate 2113 has a second arc groove 2117, and a second positioning rod 2110 is fitted inside the second arc groove 2117. The second positioning rod 2110 is slidably connected to the second arc groove 2117. A first threaded hole 222 is formed on one side of the frame 221, and the first threaded hole 222 is threadedly connected to the second positioning rod 2110. After the tilt angle of the frame 221 is adjusted to the correct position, the first positioning rod 219 and the second positioning rod 2110 are threadedly connected to the frame 221, so that the first positioning rod 219 and the second positioning rod 2110 press against the first side plate 2112 and the second side plate 2113 respectively, thereby fixing the tilt angle of the frame 221, ensuring the stability and accuracy of the tilt angle, and preventing accidental movement during the adjustment process.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a plurality of support rollers 2210 are installed inside the frame 221. Each support roller 2210 has a locking block 2211 rotatably connected to both ends. The frame 221 has locking slots 2212 on both sides, which engage with the locking blocks 2211. The mold is supported by the two support rollers 2210. The engaging structure of the locking blocks 2211 and the locking slots 2212 allows for quick installation and removal of the support rollers 2210. The support rollers 2210 can rotate, thereby providing stable support while reducing friction between the mold and the support rollers 2210. The mold can rotate freely between the two support rollers 2210, enhancing operational flexibility and adaptability.

[0034] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a screw 225 is installed inside the frame 221, the screw 225 being rotatably connected to the frame 221. A clamping plate 226 is sleeved on the screw 225, and the clamping plate 226 is threadedly connected to the screw 225. At least one positioning rod 228 is sleeved inside the clamping plate 226, the positioning rod 228 being slidably connected to the clamping plate 226, and both ends of the positioning rod 228 being fixedly connected to the frame 221. Rotating the screw 225 allows the clamping plate 226 to move axially, thereby precisely positioning the mold; simultaneously, the positioning rod 228 ensures that the clamping plate 226 remains stable during movement, preventing deflection. This improves the finishing accuracy and efficiency, and also enhances the ease of operation and reliability of the equipment.

[0035] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a handwheel 229 is fixedly connected to one end of the screw 225. By fixing the handwheel 229 to one end of the screw 225, this design makes the position adjustment of the clamping plate 226 more convenient and precise. Specifically, the operator can easily control the rotation of the screw 225 by simply rotating the handwheel 229, thereby causing the clamping plate 226 to move axially for precise positioning of the mold. The handwheel 229 also facilitates the operator's rotation of the screw 225.

[0036] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, anti-slip textures 227 are provided on one side of the inner cavity of both the clamping plate 226 and the frame 221. The anti-slip textures 227 increase the friction between the inner cavity of the clamping plate 226 and the frame 221 and the mold, effectively preventing the mold from sliding or shifting during the trimming process and improving the accuracy of mold trimming.

[0037] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the top of the workbench 1 is provided with an exhaust vent 12, and the dust collection mechanism 3 includes a first partition 31 and a second partition 33. The first partition 31 has at least one through groove 32, and a dust filter 35 is installed at one end of the through groove 32. The second partition 33 is equipped with a fan 34, and the exhaust port of the fan 34 is located between the first partition 31 and the second partition 33. When it is necessary to collect the dust and debris on the workbench 1, the fan 34 is started, and the dust and debris are sucked into the workbench 1 through the suction port 11. The dust floats with the airflow inside the workbench and is blocked by the dust filter 35 at one end of the through groove 32 on the first partition 31. Clean air is then drawn into the fan 34 through the dust filter 35 and finally discharged from the workbench 1 through the exhaust vent 12 after being processed by the fan, ensuring the cleanliness of the working area and the long-term stable operation of the equipment.

[0038] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a dust collection box 13 is provided below the dust filter 35, and the dust collection box 13 is slidably connected to the workbench 1. With the dust collection box 13 located below the dust filter 35, the micro-dust and debris blocked by the dust filter 35 can be effectively collected in the dust collection box 13. Operators can easily remove the dust collection box for cleaning, simplifying the maintenance process, reducing dust pollution of the working environment, extending the service life of the equipment, and ensuring cleanliness and safety during maintenance. This design not only improves work efficiency but also greatly facilitates daily maintenance and cleaning.

[0039] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, an air jet pipe 4 is provided inside the dust filter 35. One end of the air jet pipe 4 is connected to an air source. The periodic air jet from the air jet pipe 4 can effectively remove micro-dust from the surface of the dust filter 35, preventing it from clogging the mesh and ensuring that the dust filter always maintains high-efficiency filtration performance. By automatically removing micro-dust from the dust filter 35, the frequency of manual cleaning is reduced, the maintenance cycle of the equipment is extended, and maintenance costs and workload are reduced. A clean dust filter 35 ensures smooth airflow, improves the working efficiency of the fan 34, and reduces the increase in energy consumption caused by airflow obstruction.

The worktable 1 has a dust suction port 11, and a dust suction mechanism 3 is installed inside the worktable 1. The dust suction mechanism 3 sucks up dust from the surface of the worktable 1 through the dust suction port 11. The limiting mechanism 2 installed on the worktable 1 is mainly used to fix the cylindrical mold to be ground. Specifically, the rotating mechanism 21 serves as the basic part of the entire limiting mechanism 2, and the base 212 is fixedly connected to the worktable 1, providing stable support. The base frame 211 is mounted on the base 212 by a rotatable connection and can rotate 360 ​​degrees around the central axis of the base, allowing the operator to adjust the angle of the mold as needed to adapt to different grinding requirements. The support mechanism 22, installed within the base frame 211, is rotatably connected to the side walls of the base frame on both sides. This means the support mechanism can rotate not only horizontally but also tilt within a certain range vertically.

The dust collection mechanism 3 sucks in and collects debris and dust through the suction port 11. This design not only maintains a clean and safe working environment but also extends the service life of the equipment and improves finishing quality and efficiency.

[0042] A bearing 213 is installed between the base 212 and the base frame 211. The inner ring of the bearing 213 is fixedly connected to the base frame 211, and the outer ring of the bearing 213 is fixedly connected to the base 212. A connecting block 214 is installed on the top surface of the base 212. A sleeve 215 is fitted over the connecting block 214 and threadedly connected to the sleeve 214. A rod 216 is installed on one side of the sleeve 215. By rotating the sleeve 215 to push it upward and hold the base frame 211, a locking function can be provided during the trimming process to prevent unnecessary movement of the base frame 211, thereby ensuring the stability of the mold throughout the trimming process and improving trimming accuracy. The threaded connection design allows the operator to simply rotate the sleeve 215 to complete the height adjustment and limit locking without complicated tools or steps. The presence of the bearing 213 allows the base frame 211 to rotate smoothly on the base 212, reducing direct friction between the two.

[0043] The base frame 211 includes a base plate 2111.

A worm gear 217 is installed on one side of the first side plate 2112, and a gear is installed on one side of the connecting shaft 218. The worm gear 217 meshes with the gear. The frame 221 supports the cylindrical mold to be trimmed, ensuring its stability during the trimming process. Rotating the worm gear 217 drives the gear to rotate, which in turn rotates the connecting shaft 218. Since the connecting shaft 218 is fixedly connected to the frame 221, the frame 221 tilts as the connecting shaft 218 rotates. The meshing of the worm gear 217 and the gear not only achieves precise angle adjustment but also has a self-locking characteristic, preventing angle changes caused by external forces. The first side plate 2112 has a first arc groove 2114, within which a first positioning rod 219 is fitted. The first positioning rod 219 is slidably connected to the first arc groove 2114.

A first threaded hole 222 is opened on one side of the frame 221, and the first threaded hole 222 is threadedly connected to the second positioning rod 2110. After the tilt angle of the frame 221 is adjusted to the correct position, the first positioning rod 219 and the second positioning rod 2110 are threadedly connected to the frame 221, which further presses the first side plate 2112 and the second side plate 2113 respectively, thereby fixing the tilt angle of the frame 221, ensuring the stability and accuracy of the tilt angle, and preventing accidental movement during the adjustment process.

[0044] Several support rollers 2210 are installed inside the frame 221. Each support roller 2210 has a locking block 2211 rotatably connected to its two ends. The frame 221 has locking slots 2212 on both sides, which engage with the locking blocks 2211. The two support rollers 2210 support the mold. The engaging structure of the locking blocks 2211 and the locking slots 2212 allows for quick installation and removal of the support rollers 2210. The support rollers 2210 can rotate, thus providing stable support while reducing friction between the mold and the support rollers 2210. The mold can rotate freely between the two support rollers 2210, enhancing operational flexibility and adaptability. A screw 225 is installed inside the frame 221, rotatably connected to the frame 221. A clamping plate 226 is fitted over the screw 225, threadedly connected to the screw 225. At least one positioning rod 228 is fitted inside the clamping plate 226, slidably connected to the clamping plate 226, with both ends fixedly connected to the frame 221. Rotating the screw 225 allows the clamping plate 226 to move axially, thereby precisely positioning the mold. Simultaneously, the positioning rod 228 ensures the clamping plate 226 remains stable during movement, preventing deflection. This improves dressing accuracy and efficiency, and enhances the ease of operation and reliability of the equipment. A handwheel 229 is fixedly connected to one end of the screw 225. This design makes adjusting the position of the clamping plate 226 more convenient and precise. Specifically, the operator can easily control the rotation of the screw 225 by simply rotating the handwheel 229, thereby moving the clamping plate 226 axially for precise positioning of the mold. The handwheel 229 also facilitates the operator's rotation of the screw 225. Anti-slip textures 227 are provided on one side of the inner cavity of both the clamping plate 226 and the frame 221. The anti-slip textures 227 increase the friction between the inner cavity of the clamping plate 226 and the frame 221 and the mold, effectively preventing the mold from sliding or shifting during the finishing process and improving the accuracy of mold finishing.

[0045] The top of the workbench 1 is equipped with an exhaust vent 12. The dust collection mechanism 3 includes a first partition 31 and a second partition 33. The first partition 31 has at least one through groove 32, and a dust filter 35 is installed at one end of the through groove 32. The second partition 33 is equipped with a fan 34, and the exhaust port of the fan 34 is located between the first partition 31 and the second partition 33. When it is necessary to collect dust and debris from the workbench 1, the fan 34 is activated, and the dust and debris are sucked into the workbench 1 through the suction port 11. The dust floats with the airflow inside the workbench and is blocked by the dust filter 35 at one end of the through groove 32 on the first partition 31. Clean air is then drawn into the fan 34 through the dust filter 35 and finally discharged from the workbench 1 through the exhaust vent 12 after being processed by the fan, ensuring the cleanliness of the work area and the long-term stable operation of the equipment.

[0047] The difference between Embodiment 2 and Embodiment 1 is that a dust collection box 13 is provided below the dust filter 35, and the dust collection box 13 is slidably connected to the workbench 1. With the dust collection box 13 located below the dust filter 35, the fine dust and debris blocked by the dust filter 35 can be effectively collected in the dust collection box 13. Operators can easily pull out the dust collection box for cleaning, simplifying the maintenance process, reducing dust pollution to the working environment, extending the service life of the equipment, and ensuring cleanliness and safety during the repair process. This design not only improves work efficiency but also greatly facilitates daily maintenance and cleaning.

[0048] The implementation method of Example 3 is as follows:

[0049] The difference between Embodiment 3 and Embodiment 1 is that an air jet pipe 4 is installed inside the dust filter 35. One end of the air jet pipe 4 is connected to an air source. The periodic air jet from the air jet pipe 4 effectively removes micro-dust from the surface of the dust filter 35, preventing it from clogging the mesh and ensuring that the dust filter maintains its high-efficiency filtration performance. By automatically removing micro-dust from the dust filter 35, the frequency of manual cleaning is reduced, the maintenance cycle of the equipment is extended, and maintenance costs and workload are lowered. A clean dust filter 35 ensures smooth airflow, improves the working efficiency of the fan 34, and reduces the increase in energy consumption caused by airflow obstruction.

[0050] Specifically, the working principle of this invention is as follows:

[0051] The grinding table uses a limiting mechanism 2 mounted on the worktable 1 to fix the cylindrical mold to be ground. The limiting mechanism 2 includes a rotating mechanism 21 and a supporting mechanism 22. A bearing 213 is provided between the base 212 and the base frame 211, allowing the base frame 211 to rotate smoothly 360 degrees around the central axis of the base, providing flexible angle adjustment. The supporting mechanism 22 is rotatably connected to the side walls of the base frame 211 on both sides, allowing it to rotate horizontally and tilt vertically, providing multi-dimensional operating space for the grinding tools and ensuring that the operator can process the mold surface at the optimal angle.

[0052] The tilt adjustment of the support mechanism 22 is achieved through the meshing of the worm gear 217 and the gear. The operator can precisely control the tilt angle of the frame 221 by rotating the worm gear 217. After the tilt angle is adjusted to the correct position, the first positioning rod 219 and the second positioning rod 2110 are threadedly connected to the frame 221 to further fix the tilt angle of the frame 221, ensuring its stability and accuracy. In addition, the sleeve 215 on the top surface of the base 212 is threadedly connected to the connecting block 214. By rotating the sleeve 215, it is pushed upward and pressed against the bottom frame 211, providing an additional locking function to prevent unnecessary rotation of the bottom frame 211 during the trimming process, thereby improving the trimming accuracy.

[0053] Several support rollers 2210 are installed inside the frame 221. These support rollers 2210 can rotate freely, reducing friction and providing stable support. The mold can rotate freely between two support rollers, enhancing operational flexibility. The clamping plate 226 achieves precise axial positioning through a combination of screw 225 and handwheel 229. The positioning rod 228 ensures that the clamping plate 226 remains stable during movement. Anti-slip grooves 227 are provided on one side of the inner cavity of both the clamping plate 226 and the frame 221, increasing the friction between the clamping plate and the mold and effectively preventing the mold from sliding or shifting during the dressing process, further improving the dressing accuracy and reliability.

[0054] When it is necessary to remove dust and debris from workbench 1, the fan 34 is activated, and the dust and debris are sucked into workbench 1 through the suction port 11. The dust floats with the airflow inside the workbench and is blocked by the dust filter 35, while clean air is drawn into the fan 34 through the dust filter 35. Finally, after being processed by the fan, the air is discharged outside workbench 1 through the exhaust port 12, ensuring the cleanliness of the work area and the long-term stable operation of the equipment.

[0055] In summary, this utility model solves the problems of inconvenient angle adjustment and inconvenient cleaning of dust and debris generated during the trimming process of cylindrical aluminum alloy casting molds.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0057] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
