Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to a small grinding equipment for mold repair. Background Technology

[0002] Mold repair refers to the process of inspecting, repairing, and adjusting worn, deformed, or damaged molds to restore their precision, function, and lifespan. This includes cleaning residues, assessing damage (such as cracks, chipped corners, dimensional deviations, etc.), and repairing them using methods such as welding, grinding, polishing, and insert replacement. The repair effect is then verified through trial molding. Small grinding equipment for mold repair mainly refers to portable or benchtop precision grinding tools, such as pneumatic / electric grinding pens, small mold EDM machines, precision engraving machines, and micro milling machines. These tools are suitable for local fine finishing, corner clearing, polishing, and complex surface repair. They are characterized by flexible operation and high precision, which can improve mold repair efficiency and reduce manual grinding errors.

[0003] When using an electric grinding pen to grind molds, a large amount of fine metal dust is generated. This metal dust can easily spread into the working environment, which not only endangers the health of operators (such as respiratory diseases caused by inhaling dust), but may also affect the accuracy of the equipment or contaminate the surface of the mold. Therefore, a small grinding device for mold repair is needed to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a small grinding device for mold repair, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A small grinding device for mold repair includes a handheld electric grinding pen. A ring magnet is fixedly fitted onto the handheld electric grinding pen. A protective component is installed on the ring magnet. The protective component consists of a first arc-shaped shell, an arc-shaped magnet, a connecting support rod, a second arc-shaped shell, a threaded connecting pipe, an arc-shaped protective net, and T-shaped guide rails. The arc-shaped magnet is fixedly installed inside the first arc-shaped shell. The second arc-shaped shell and the first arc-shaped shell are connected by the connecting support rod. The threaded connecting pipe is fixedly installed on the outer wall of the second arc-shaped shell. The arc-shaped protective net is fixedly installed on the inner wall of the second arc-shaped shell. Two T-shaped guide rails are symmetrically fixedly installed on the outer wall of the second arc-shaped shell. An arc-shaped baffle is fitted onto the T-shaped guide rails.

[0006] Preferably, the handheld electric polishing pen is equipped with a polishing head.

[0007] Preferably, the first arc-shaped housing on the protective component is sleeved on the annular magnet, the arc-shaped magnet and the annular magnet are attracted together, and the connecting support rod is fixedly connected to the first arc-shaped housing and the second arc-shaped housing.

[0008] Preferably, the second arc-shaped housing on the protective assembly is located on one side of the grinding head, and the threaded connecting pipe is located between the two T-shaped guide plates.

[0009] Preferably, a T-shaped guide groove is provided on the inner wall of the arc-shaped baffle, and the arc-shaped baffle is sleeved on the T-shaped guide plate through the T-shaped guide groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By incorporating a ring magnet, a protective component, and an arc-shaped baffle on the handheld electric polishing pen, a flexible hose can be used to connect the protective component to a dust collection device when grinding molds with the pen's polishing head. This allows for the timely collection of generated metal dust, reducing the probability of dust dispersion, improving the working environment, and ultimately benefiting the operator's health. It also reduces the likelihood of mold surface contamination by metal dust, improving mold repair quality. Simultaneously, the ring magnet and arc-shaped magnet facilitate the disassembly and assembly of the protective component, simplifying equipment maintenance and cleaning without affecting the normal use of the handheld electric polishing pen. The arc-shaped baffle, through the cooperation of a T-shaped guide groove and a T-shaped guide plate, can be flexibly adjusted in position according to actual grinding needs, effectively blocking dust splashes and further improving dust collection efficiency.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a small grinding device for mold repair includes a handheld electric grinding pen 1. A ring magnet 2 is fixedly mounted on the handheld electric grinding pen 1. A protective component 3 is installed on the ring magnet 2. The protective component 3 consists of a first arc-shaped housing 6, an arc-shaped magnet 7, a connecting support rod 8, a second arc-shaped housing 9, a threaded connecting pipe 10, an arc-shaped protective net 11, and T-shaped guide plates 12. The arc-shaped magnet 7 is fixedly installed inside the first arc-shaped housing 6. The second arc-shaped housing 9 and the first arc-shaped housing 6 are connected by the connecting support rod 8. The threaded connecting pipe 10 is fixedly installed on the outer wall of the second arc-shaped housing 9. The arc-shaped protective net 11 is fixedly installed on the inner wall of the second arc-shaped housing 9. Two T-shaped guide plates 12 are symmetrically fixedly installed on the outer wall of the second arc-shaped housing 9. An arc-shaped baffle 4 is mounted on the T-shaped guide plate 12. A grinding head 5 is installed on the head of the handheld electric grinding pen 1. When using this small grinding device for mold repair, the protective component 3 is first... The ring magnet 2 and the arc magnet 7 are fixed to the handheld electric polishing pen 1 by adsorption, ensuring that the second arc housing 9 is located on one side of the polishing head 5. Then, the hose is connected to the vacuum cleaner through the threaded connecting pipe 10. At the same time, the position of the arc baffle 4 is adjusted to cover the polishing area. After starting the handheld electric polishing pen 1 and the vacuum cleaner, the polishing operation can be carried out. At this time, the handheld electric polishing pen 1 will drive the polishing head 5 to rotate at high speed. When the handheld electric polishing pen 1 drives the polishing head 5 to polish the mold, the generated metal powder will be blocked by the protective component 3 and the arc baffle 4. Then, the negative pressure generated by the operation of the vacuum cleaner will suck the metal dust into the vacuum cleaner through the second arc housing 9 and the threaded connecting pipe 10 on the protective component 3, thereby effectively reducing the dust diffusion. When the protective component 3 and the arc baffle 4 are not needed, the protective component 3 can be removed from the ring magnet 2. The method is to simply detach the arc magnet 7 from the ring magnet 2.

[0015] Specifically, the first arc-shaped housing 6 on the protective component 3 is fitted onto the ring magnet 2, and the arc-shaped magnet 7 and the ring magnet 2 are attracted together. The connecting support rod 8 is fixedly connected to the first arc-shaped housing 6 and the second arc-shaped housing 9. The second arc-shaped housing 9 on the protective component 3 is located on one side of the grinding head 5. The threaded connecting pipe 10 is located between the two T-shaped guide plates 12. When the dust collection equipment connected to the threaded connecting pipe 10 on the protective component 3 through the hose is working, it will suck the metal dust generated by grinding into the second arc-shaped housing 9. Then the metal dust will enter the dust collection equipment through the threaded connecting pipe 10 and the hose.

[0016] Specifically, a T-shaped guide groove 13 is provided on the inner wall of the arc-shaped baffle 4. The arc-shaped baffle 4 is fitted onto the T-shaped guide plate 12 through the T-shaped guide groove 13. In use, the position of the arc-shaped baffle 4 on the T-shaped guide plate 12 is slid according to the size and shape of the grinding area so that it completely covers the dust splash range and ensures that the dust collection efficiency is maximized.

[0017] Finally, by setting a ring magnet 2 on the handheld electric polishing pen 1, a protective component 3 on the ring magnet 2, and an arc-shaped baffle 4 on the protective component 3, when using the polishing head 5 on the handheld electric polishing pen 1 to grind the mold, a flexible hose can be used to connect the protective component 3 to a dust collection device. This allows for timely collection of generated metal dust, reducing the probability of metal dust diffusion, improving the working environment, and ultimately benefiting the operator's health. It also reduces the probability of the mold surface being contaminated by metal dust, improving the quality of mold repair. At the same time, the ring magnet 2 and the arc-shaped magnet 7 work together to facilitate the disassembly and assembly of the protective component 3, making equipment maintenance and cleaning easier without affecting the normal use of the handheld electric polishing pen 1. The arc-shaped baffle 4, through the cooperation of the T-shaped guide groove 13 and the T-shaped guide plate 12, can be flexibly adjusted in position according to actual grinding needs, effectively blocking dust splashes and further improving dust collection efficiency.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
