Description

Technical Field

[0001] This utility model relates to the field of graphite mold processing technology, specifically a graphite mold surface processing device. Background Technology

[0002] The significance of surface finishing for graphite molds lies in improving their overall performance and service life. Precision machining (such as grinding, polishing, or coating) can significantly improve mold surface finish, reduce friction and wear, thereby lowering resistance during product demolding and improving molding accuracy and surface quality. Simultaneously, machining can eliminate surface defects (such as cracks and porosity), enhancing the mold's compressive strength and thermal shock resistance, preventing cracking or deformation at high temperatures. Furthermore, optimized surfaces reduce material adhesion, facilitating cleaning and maintenance, and lowering production costs. Ultimately, high-quality surface finishing is crucial for ensuring efficient and stable mold operation and improving product yield.

[0003] Utility model announcement CN211136644U discloses a surface finish treatment device for graphite molds, including a base. The base is a hollow cuboid structure. A first motor is installed on the side of the base. The output shaft of the first motor is inserted into the interior of the base and connected to a rotating shaft. A first bevel gear is fixedly sleeved on the rotating shaft. A support column is fixed at one end of the top of the base. A first sliding groove is opened on the side of the support column. A lead screw is rotatably connected to the interior of the first sliding groove through a bearing. The bottom of the lead screw passes through the first sliding groove and is inserted into the interior of the base. A second bevel gear is fixedly sleeved on the bottom of the lead screw. A sliding plate is threaded onto the lead screw. This utility model improves the grinding accuracy of the device and the polishing accuracy of the product by repeatedly adjusting the distance between the polishing roller and the mold. It also facilitates the collection and cleaning of waste during polishing, resulting in high cleaning efficiency.

[0004] Although the above-mentioned device is equipped with a dust collection hood to absorb waste, the dust collection hood is only located on one side of the grinding structure, resulting in a small coverage area during operation. The adsorption effect on the side away from the dust collection hood is limited, making it difficult to ensure that as much dust as possible is absorbed and treated during the grinding process. Therefore, it cannot play a good cleaning role. Furthermore, since there is no filtration and blocking measures for dust and debris in the collection box, dust and debris will directly enter the exhaust equipment, which can easily cause damage to the equipment. Therefore, in order to address the above problems, a graphite mold surface processing device is proposed. Utility Model Content

[0005] To address the technical problems of poor dust and debris absorption during the processing of graphite mold processing devices in comparative technologies, which easily lead to dust and debris contaminating the processing environment and causing dust and debris to directly enter the exhaust equipment and damage the equipment, this utility model provides a graphite mold surface processing device.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A graphite mold surface processing device includes a movable clamp for loading and fixing the graphite mold to be processed; a hydraulic lifting frame disposed on one side of the movable clamp, and a mounting frame mounted on it directly above the movable clamp; a grinding mechanism mounted on the mounting frame for grinding the graphite mold; and an absorption hood mounted on the upper side of the grinding mechanism, with a sealed elastic air pipe connected to its top. The top of the elastic air pipe is mounted on the hydraulic lifting frame via a pipe support. A liquid adsorption tank and an air extraction device are disposed on one side of the hydraulic lifting frame, and the elastic air pipe, liquid adsorption tank, and air extraction device are sequentially connected by pipes.

[0007] In one possible implementation, the absorption cover includes a shell with an inner liner having several ventilation holes installed inside. The inner liner and the shell enclose a negative pressure cavity, and the top of the shell has an exhaust hole communicating with the negative pressure cavity.

[0008] In one possible implementation, the grinding mechanism includes a grinding roller rotatably mounted on the bottom of the mounting frame, and a protective cover mounted on the side of the mounting frame. A grinding motor is mounted on the protective cover, which drives the grinding roller to rotate via a belt drive assembly located inside the protective cover.

[0009] In one possible implementation, the wheel drive assembly includes two drive wheels connected by a transmission belt, wherein one drive wheel is fixedly connected to the shaft end of the grinding roller, and the other drive wheel is fixedly connected to the shaft end of the grinding motor.

[0010] In one possible implementation, the movable clamp includes a base plate, on the upper surface of which a symmetrically arranged guide rod frame is fixedly mounted, and a drive motor is fixedly mounted at the end of the guide rod frame. A transmission screw is fixedly connected to the shaft end of the drive motor. A movable platform is slidably mounted on the guide rod frame, and a sliding seat and a transmission platform are fixedly mounted on the lower surface of the movable platform. The sliding seat is slidably connected to the guide rod frame, and the transmission platform is threadedly connected to the transmission screw.

[0011] In one possible implementation, one end of the movable platform is threadedly connected to a pressing screw, and the other end is rotatably connected to a pressing plate, with the bottom end of the pressing plate slidingly attached to the upper surface of the movable platform.

[0012] In one possible implementation, the hydraulic lifting frame includes a cantilever frame with a hydraulic cylinder fixedly mounted on its top. The mounting frame is fixedly connected to the shaft end of the hydraulic cylinder, and guide rods that are slidably connected to the cantilever frame are fixedly provided on both sides of the upper end face of the mounting frame.

[0013] In one possible implementation, the liquid adsorption tank includes a main body containing clean water, and an air inlet pipe and an air outlet pipe installed on its top plate, wherein the bottom end of the air inlet pipe is below the liquid surface and the bottom end of the air outlet pipe is above the liquid surface.

[0014] In summary, this utility model has the following beneficial technical effects: By installing an absorption hood that can completely cover the grinding mechanism on the upper side, when the grinding mechanism is working, the suction equipment can work simultaneously to create negative pressure in the negative pressure chamber formed by the inner liner and the shell inside the absorption hood, thereby absorbing the dust and debris generated during the processing. Furthermore, since the entire absorption hood can move synchronously with the grinding mechanism, it can ensure that its absorption range can always cover the entire working area, preventing dust and debris from escaping and polluting the processing environment. In addition, air carrying dust and debris will pass through a liquid adsorption box before entering the extraction equipment. Since the box contains cleaning water, when the air is injected into the water, the dust and debris contained in the air will be adsorbed by the water and deposited in the liquid adsorption box, thereby improving the cleanliness of the gas sent out from the liquid adsorption box and avoiding damage to the extraction equipment due to a high content of large particles.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2 As shown, this embodiment provides a graphite mold surface processing device, including a movable clamping seat 1 for loading and fixing the graphite mold to be processed; a hydraulic lifting frame 2, which is disposed on one side of the movable clamping seat 1, and a mounting frame 3 is installed on it directly above the movable clamping seat 1; a grinding mechanism 4, which is installed on the mounting frame 3 for grinding the graphite mold; an absorption cover 5, which is installed on the upper side of the grinding mechanism 4, and its top is connected to a sealed elastic air pipe 6, the top of which is mounted on the hydraulic lifting frame 2 through a pipe bracket 61; wherein, a liquid adsorption box 7 and an air extraction device 8 are disposed on one side of the hydraulic lifting frame 2, and the elastic air pipe 6, the liquid adsorption box 7 and the air extraction device 8 are connected in sequence by pipes.

[0018] Based on the above structural design, when the grinding mechanism 4 is working, the suction device 8 can simultaneously create negative pressure inside the absorption hood 5 to absorb the dust and debris generated during the processing. Since the absorption hood 5 can move synchronously with the grinding mechanism 4, it can ensure that its absorption range always covers the entire working area, preventing dust and debris from escaping and polluting the processing environment. In addition, the air carrying dust and debris will pass through the liquid adsorption box 7 before entering the suction device 8. Since the liquid adsorption box contains cleaning water, when the air is injected with water, the dust and debris contained inside will be adsorbed by the water and deposited in the liquid adsorption box 7, improving the cleanliness of the gas sent out from the liquid adsorption box 7 and preventing damage to the suction device 8 due to the high content of large-sized particles.

[0019] like Figure 3As shown, the absorption hood 5 includes a cover 51, inside which is installed an inner liner 52 with several ventilation holes. The inner liner 52 and the cover 51 enclose a negative pressure cavity, and the top of the cover 51 is provided with an exhaust port 53 that communicates with the negative pressure cavity. Based on the above structural scheme, when the exhaust device 8 is working, it can form a negative pressure in the negative pressure cavity formed by the inner liner 52 and the cover 51 through the elastic air pipe 6, thereby absorbing the dust and debris generated during the processing into the negative pressure cavity through the ventilation holes, and then transporting it to the liquid adsorption box 7 through the exhaust port 53 and the elastic air pipe 6.

[0020] like Figure 3 As shown, the grinding mechanism 4 includes a grinding roller 41 rotatably mounted at the bottom of the mounting frame 3 and a protective cover 42 mounted on the side of the mounting frame 3. A grinding motor 43 is mounted on the protective cover 42, which drives the grinding roller 41 to rotate through a wheel belt drive assembly 44 located inside the protective cover 42. The wheel belt drive assembly 44 includes two drive wheels connected by a transmission belt. One drive wheel is fixedly connected to the shaft end of the grinding roller 41, and the other drive wheel is fixedly connected to the shaft end of the grinding motor 43. Based on the above structural scheme, when processing is required, the grinding motor 43 drives the drive wheel fixedly connected to it to rotate, and drives the other drive wheel to rotate under the transmission action of the transmission belt, thereby driving the grinding roller 41 to rotate, and thus grinding and polishing the surface of the graphite mold.

[0021] like Figure 4 - Figure 5 As shown, the movable clamp 1 includes a base plate 11, on which a symmetrically arranged guide rod frame 12 is fixedly mounted, and a drive motor 14 is fixedly mounted at its end. A transmission screw 15 is fixedly connected to the shaft end of the drive motor 14. A movable platform 13 is slidably mounted on the guide rod frame 12. A sliding seat 131 and a transmission table 132 are fixedly mounted on the lower end surface of the movable platform 13. The sliding seat 131 is slidably connected to the guide rod frame 12, and the transmission table 132 is threadedly connected to the transmission screw 15. Based on the above structural scheme, when the drive motor 14 is working, it can drive the transmission table 132 to move through the transmission screw 15, thereby driving the movable platform 13 to move as a whole to drive the graphite mold placed on it, so that the grinding roller 41 can perform grinding and polishing treatment on different positions of the mold.

[0022] In addition, one end of the movable platform 13 is threadedly connected to an extrusion screw 17, and an extrusion plate 16 is rotatably connected to its end. The bottom end of the extrusion plate 16 slides against the upper surface of the movable platform 13. When the extrusion screw 17 is turned, it can drive the extrusion plate 16 connected to its end to move toward the placed graphite mold, thereby cooperating with the movable platform 13 to clamp and fix the graphite mold, preventing it from shifting during processing and affecting the processing effect.

[0023] like Figure 2As shown, the hydraulic lifting frame 2 includes a cantilever frame 21, on the top of which a hydraulic cylinder 22 is fixedly installed. The mounting frame 3 is fixedly connected to the shaft end of the hydraulic cylinder 22, and guide rods 23 that are slidably connected to the cantilever frame 21 are fixedly installed on both sides of the upper end face of the mounting frame 3. When the hydraulic cylinder 22 is working, it can drive the mounting frame 3 to move up and down, thereby driving the grinding roller 41 to move up and down, ensuring that the grinding roller 41 can always be in contact with the surface of the graphite mold when working. The setting of the guide rods 23 can ensure that the mounting frame 3 is more stable during the up and down movement and is less prone to deviation.

[0024] like Figure 6 As shown, the liquid adsorption box 7 includes a box body 71, which contains cleaning water. An air inlet pipe 72 and an air outlet pipe 73 are installed on its top plate. The bottom end of the air inlet pipe 72 is below the liquid surface, and the bottom end of the air outlet pipe 73 is above the liquid surface. The above structure can ensure that the gas entering the box body 71 can fully contact the cleaning water to remove large particles of dust and debris. At the same time, it can also prevent the cleaning water from overflowing from the air outlet pipe 73 under air pressure.

[0025] The working principle and usage process of this utility model: When the hydraulic cylinder 22 is working, it can drive the mounting frame 3 to move up and down, thereby driving the grinding roller 41 to move up and down, ensuring that the grinding roller 41 can always be in contact with the surface of the graphite mold during operation. When the grinding and polishing process is being performed, the drive motor 14 can drive the transmission table 132 to move through the transmission screw 15, thereby driving the movable platform 13 to move as a whole to drive the graphite mold placed on it, so that the grinding roller 41 can perform grinding and polishing processes on different positions of the mold.

[0026] During the processing, the extraction device 8 works synchronously to create negative pressure in the negative pressure chamber formed by the inner liner 52 and the cover 51 through the elastic air pipe 6. This allows the dust and debris generated during the processing to be absorbed into the negative pressure chamber through the vent holes and transported to the liquid adsorption box 7 through the extraction hole 53 and the elastic air pipe 6. Since the liquid adsorption box 7 contains cleaning water, when air is injected into the water, the dust and debris contained inside will be adsorbed by the water and deposited in the liquid adsorption box 7, improving the cleanliness of the gas sent out from the liquid adsorption box 7 and avoiding damage to the extraction device 8 due to the high content of large-sized particles.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
