Casting abrasive tools can be designed and manufactured according to different shapes and sizes of castings to ensure the accuracy and quality of castings. Casting abrasive tools are widely used in fields such as automobiles, aerospace, and mechanical manufacturing.

[0003] During the grinding process of casting abrasive tools, in order to ensure the safety of operators and prevent the flying of debris generated by grinding from affecting the surrounding environment, a protection mechanism is usually set up. The existing grinding protection mechanisms for casting abrasive tools mainly adopt structures such as transparent baffles or protective covers, which can block the flying of debris generated during the grinding process to a certain extent. However, these existing protection mechanisms only play a protective role and cannot collect a large amount of debris generated during the grinding process. This results in the need to spend a lot of time and manpower to clean up the debris scattered everywhere in the work area after the grinding work is completed, which not only increases the cleaning cost but also reduces the work efficiency. Summary of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a grinding protection mechanism for a casting mold, including a grinding assembly and a cover 5. The grinding assembly includes a mounting seat 1, and the mounting seat 1 is installed at the working end of an external driving assembly. The mounting seat 1 is driven to rotate by the external driving assembly. The driving assembly is a necessary structure for the grinding mechanism of the casting mold and belongs to the prior art, so no more details will be described here. A rotating shaft 2 is fixedly connected to the bottom of the mounting seat 1, and a grinding head 3 is fixedly connected to the bottom of the rotating shaft 2. By driving the mounting seat 1 and the rotating shaft 2 to rotate through the driving assembly, the grinding head 3 can be rotated, thereby grinding the surface of the workpiece. The grinding assembly is rotatably connected inside the cover 5, and the cover 5 is used to protect the grinding assembly to prevent debris from splashing.

[0033] Refer to Figures 2 - 4, a positioning ring 4 is fixedly connected to the outside of the rotating shaft 2. The rotating shaft 2 is rotatably connected to the middle of the cover 5 through the positioning ring 4. After adding the positioning ring 4, the stability of the installation of the cover 5 can be ensured, and the smooth rotation of the grinding head 3 can be ensured. The bottom of the cover 5 is provided with a connecting ring 8 through an elastic component. After adding the elastic component, the position of the connecting ring 8 can be adjusted according to the distance that the grinding head 3 is pressed down to ensure the protection effect on the debris. The elastic component includes a spring rod 7. The spring rod 7 is fixedly connected to the bottom of the cover 5, and the connecting ring 8 is fixedly connected to the bottom of the spring rod 7 for adjusting the position of the connecting ring 8. The spring rod 7 contracts when stressed and pops out when released, thereby adjusting the position of the connecting ring 8.

[0034] Refer to Figures 4 - 5 , a magnet 12 is fixedly connected to the bottom of the connecting ring 8, and an aggregate drawer 9 is installed at the bottom of the magnet 12. The aggregate drawer 9 is made of materials such as iron, cobalt, and nickel that can be attracted by the magnet 12, or such materials are installed at the connection with the connecting ring 8. These are all common means to achieve this purpose and will not be elaborated here. The aggregate drawer 9 is used to collect the debris generated by grinding. At the same time, because the aggregate drawer 9 and the connecting ring 8 are connected by the magnet 12, after the aggregate drawer 9 collects the debris, the aggregate drawer 9 can be directly removed from the bottom of the connecting ring 8 for cleaning the debris. An inclined angle is provided at the inner edge of the aggregate drawer 9 for the debris to enter. The debris generated during the grinding process can move deeper into the aggregate drawer 9 along the inclined angle, thereby improving the collection efficiency of the debris. A convex block 11 is provided at the bottom of the connecting ring 8, and the magnet 12 is fixedly connected to the outside of the convex block 11. A groove 13 is fixedly connected to the inside of the aggregate drawer 9. The sizes of the convex block 11 and the groove 13 are adapted to each other. When connecting the aggregate drawer 9 and the connecting ring 8, first align the groove 13 inside the aggregate drawer 9 with the convex block 11 outside the connecting ring 8, and then complete the clamping of the aggregate drawer 9 and the connecting ring 8 through the convex block 11 and the groove 13. After adsorbing the aggregate drawer 9 by the magnet 12, the connection strength and the stability after connection can be further ensured.

[0035] Refer to Figure 4, a cleaning component is also fixedly connected to the middle of the cover 5 for cleaning the debris at the grinding position. The cleaning component can be connected to an external water source or gas source, and the debris can be cleaned by injecting gas or water into the interior of the cover 5. The cleaning component includes a shunt pipe 14, which is fixedly connected inside the cover 5. A connecting pipe 15 is fixedly connected to the top of the shunt pipe 14, and a plurality of nozzles 16 are fixedly connected to the bottom of the shunt pipe 14. After connecting the connecting pipe 15 to an external water source or gas source, the injected water or gas is conveyed into the interior of the shunt pipe 14, dispersed by the shunt pipe 14 to each nozzle 16, and then discharged from the nozzles 16 to clean the debris on the surface of the workpiece, thereby avoiding overheating during the grinding of the workpiece and also avoiding the impact on grinding caused by the accumulation of debris. A plurality of groups of through holes 10 are formed on the outer side of the aggregate drawer 9, and the injected water body or gas can be discharged from the through holes 10.

[0036] Referring to Figure 1 and Figure 4 , a transparent observation window 6 is fixedly connected to the middle of the cover 5, and the interior of the cover 5 can be observed through the transparent observation window 6. A plurality of mounting posts 17 are fixedly connected to the outer side of the cover 5, and the cover 5 can be connected to the mounting frame of the grinding component through the mounting posts 17.

[0037] Working principle: Mount the cover 5 on the mounting bracket of the grinding component through the mounting posts 17, then connect the mounting seat 1 to the driving structure of the grinding component, and drive the mounting seat 1 to rotate through the driving structure, which can drive the grinding head 3 to rotate. Then move the grinding head 3 closer to the workpiece to grind the workpiece. When the grinding head 3 contacts the workpiece, the aggregate drawer 9 will first contact the surface of the workpiece. Under the continuous downward movement of the grinding head 3, the spring rod 7 contracts, which can ensure that the aggregate drawer 9 fully contacts the workpiece. Then connect an external water source or gas source to the connecting pipe 15, and the water or gas is conveyed from the shunt pipe 14 to the nozzles 16, and then sprayed out from the nozzles 16 to cool the contact position between the workpiece and the grinding head 3. Then when the grinding head 3 contacts the workpiece, the surface of the workpiece is ground. At this time, the debris generated by grinding splashes outwards and is blocked by the aggregate drawer 9, while the waste gas or waste water flows out from the through holes 10, and the debris is blocked by the aggregate drawer 9 and accumulates on the upper part of the aggregate drawer 9. After grinding is completed, just pull the aggregate drawer 9 downward to separate the aggregate drawer 9 from the connecting ring 8, which facilitates the cleaning of the debris collected on the upper part of the aggregate drawer 9, thereby avoiding the problems of increased cleaning cost and reduced work efficiency caused by the scattering of debris on the workbench after grinding.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
