Description

Technical Field

[0001] The utility model belongs to the technical field of mold grinding, and in particular relates to a mold grinding device with an anti-blocking function. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. With the increasing application of molds, the appearance quality of products produced by molds is becoming higher and higher, so the quality of the surface roughness of the mold cavity must also be improved accordingly, especially for products with mirror and high-gloss surfaces, which have higher requirements for the surface roughness of the mold.

[0003] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Therefore, grinding is a very important process in the mold making process. It not only increases the beauty of the workpiece, but also improves the corrosion resistance and wear resistance of the material surface. It can also facilitate subsequent injection molding processing, such as making plastic products easier to demold and reducing the production injection molding cycle.

[0004] In the prior art, manual polishing is required for polishing molds, especially for special-shaped surfaces and small areas such as small grooves, and manual polishing requires a polishing pen. The polishing pen will produce a large amount of debris during the polishing process, and the generated debris will splash during operation, which not only pollutes the environment, but also the staff will inhale a certain amount of debris into the nasal cavity during the polishing process, affecting their health, so the debris needs to be cleaned. The prior art discloses that a debris suction device is set in the polishing pen, such as the authorization announcement number CN 218874941U, which specifically discloses an automatic dust suction polishing pen, including a polishing pen body, a fixed component, and a dust suction pipe. The fixed component fixes the dust suction pipe at the upper end of the polishing pen body, and the dust suction pipe is externally connected to a vacuum pump; this utility model provides an automatic dust suction polishing pen that is easy to use and low in cost. Because the manual polishing pen is relatively small, the diameter of the dust suction pipe that matches the polishing pen is relatively small. After long-term polishing, the dust suction device often has a blockage problem. Utility Model Content

The power input interface is electrically connected to an external power source, the power device is connected to the power input interface, the power button 12 is installed on the outside of the polishing pen body 1, and the polishing head 11 is installed at the output end of the power device. When in use, the power input interface is plugged into the power source, the power button 12 is pressed, the power device is electrically connected to the external power source, the power device drives the polishing head 11 to rotate, and the polishing head 11 contacts the surface of the mold to be polished to perform the polishing operation.

[0033] In one embodiment, a large amount of debris is generated during the grinding process when the mold surface is polished, so a dust suction component 2 is provided on the polishing pen body 1 to remove the debris. The dust suction component 2 is detachably mounted on the outer side of the polishing pen body 1.

[0034] Specifically, the dust suction assembly 2 includes a shell 21, and an external thread is provided on the outer surface of the middle part of the grinding pen body 1. The shell 21 is provided with a working chamber 210 for accommodating the grinding pen body 1, and the inner wall of the working chamber 210 is provided with an internal thread matching the external thread. Through the thread matching, not only the shell 21 is fixedly installed on the grinding pen body 1, but also the distance between the tail end of the shell 21 and the end of the grinding head 11 can be adjusted, so as to be suitable for grinding heads 11 of different specifications.

[0035] The side wall of the shell 21 is provided with a cavity 211 in the circumferential direction. The end of the cavity 211 close to the grinding head 11 is provided with a chip suction port 212. The outer side of the upper part of the shell 21 is provided with a chip discharge port 213. The chip suction port 212, the chip discharge port 213 and the cavity 211 form a chip discharge channel 214. The chip discharge port 213 is exposed outside the shell 21 and connected to an external dust collection device. In order to prevent the grinding head 11 from being affected by the shell 21 during the grinding process, the lower end of the grinding head 11 is exposed at the rear end of the shell 21.

[0036] On the basis of the above embodiment, the outer wall of the housing 21 near the chip suction port 212 is provided with a plurality of auxiliary chip suction holes 215 at intervals, and the auxiliary chip suction holes 215 are connected with the cavity 211. During the operation and grinding process of the dust suction component 2, light dust will fly. With this structure, the flying dust is sucked away by the auxiliary chip suction holes 215, thereby protecting the health of the operator.

[0037] On the basis of the above embodiment, during the grinding process, the grinding head 11 grinds out powder and sometimes there will be debris. In order to prevent the operator from being splashed by the debris and control the flying dust in a limited space, the dust collection assembly 2 is provided with a dust collection hood 22. The dust collection hood 22 is trumpet-shaped as a whole and is made of elastic transparent plastic material. The diameter of one end installed on the outside of the shell 21 is smaller than the outer diameter of the shell 21. Depending on the working conditions, the dust collection hood 22 can be selectively slidably mounted on the outside of the shell 21 near the chip suction port 212.

[0038] In one embodiment, the driving component 3 is a motor 31, and the housing 21 is provided with a motor cavity 216 for installing the motor. The motor 31 is fixedly installed in the motor cavity 216. A hole 217 is provided in the housing 21. The output end of the motor 31 extends out of the hole 217 and enters the chip removal channel 214.

[0039] In one embodiment, the clearing assembly 4 is rotatably mounted on the output end of the driving assembly 3 , and in the chip removal channel 214 , the driving assembly 3 drives the clearing assembly 4 to stir in the chip removal channel 214 to break up the chips in the chip removal channel 214 .

[0040] Specifically, the clearing assembly 4 includes a ring plate 41 and a plurality of scrapers 42. The ring plate 41 is mounted at the output end of the motor 31, and the plurality of scrapers 42 are installed at intervals on the end surface of the ring plate 41 away from the motor 31, and the scrapers 42 are installed in the cavity 211. The motor 31 drives the scrapers 42 to rotate in the cavity 211. When rotating, the scrapers 42 will crush the accumulated debris when encountering the accumulated debris, and the debris will be sucked away by the dust suction assembly 2, so that the chip removal channel 214 remains unobstructed, and the chip removal channel 214 is prevented from being blocked.

[0041] On the basis of the above embodiment, in order to facilitate the crushing of the debris, the scraper 42 is provided with sharp edges along the circumference. Preferably, in order to enhance the stirring strength of the scraper 42 on the debris, the scraper 42 is made of metal material, such as stainless steel.

[0042] On the basis of the above embodiment, in order to facilitate observation of the grinding operation process of the grinding head 11 on the mold and the working state of the clearing assembly 4, the housing 21 is made of a transparent plastic material.

[0043] During use, the mold polishing device with anti-blocking function is regularly maintained or when the shell 21 is found to be blocked, the external dust collection equipment is started, the motor 31 is started, and the motor 31 can rotate in forward and reverse directions, thereby driving the scraper 42 to rotate back and forth in the cavity 211. The scraper 42 will crush the chips in the shell 21. After the chips are crushed, they can be easily sucked away by the dust collection equipment, so that the chip removal channel 214 remains unobstructed and the chip removal channel 214 is prevented from being blocked.
