Description

[0002] With the development of industrial manufacturing, molds are playing an increasingly important role in the production of precision parts. However, existing mold grinding equipment has some technical bottlenecks, which restrict the improvement of mold processing accuracy and efficiency, and also bring environmental and safety hazards.

[0003] First, existing mold grinding equipment generates a large amount of chips during the processing. These chips often float in the air, posing a threat to the health of workers and can also enter the equipment, accumulating and causing a decrease in equipment precision, or even leading to equipment failure.

[0004] Secondly, the grinding disc generates a lot of heat during the grinding process, causing the temperature of the grinding disc to rise rapidly.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0037] like Figures 1 to 9As shown, a mold grinding device according to one embodiment of the present invention includes a body 1, a moving mechanism 2 installed inside the body 1, the moving mechanism 2 including multiple guide rails 21, and sliders 22 slidably connected to the guide rails 21. The mold grinding device also includes a clamping mechanism 4, a grinding mechanism 5, a cooling mechanism 6, a slag collection mechanism 7, and a central control mechanism 3. The clamping mechanism 4 includes multiple first hydraulic pumps 41 and second hydraulic pumps 42, the second hydraulic pumps 42 being welded to the telescopic rods of the first hydraulic pumps 41, and the multiple second hydraulic pumps 42 being used to clamp the mold to be ground. The grinding mechanism 5 is provided with a rotating tube 54, a grinding disc 55 detachably connected to the rotating tube 54, mounting holes 552 matching the rotating tube 54 on the grinding disc 55, a slag guide groove 554 on the grinding surface of the grinding disc 55, and a cooling chamber 551 inside the grinding disc 55. The cooling mechanism 6 includes a cooling tank 61, which is connected to the cooling chamber 551. The cooling gas generated by the cooling tank 61 is used to reduce the temperature of the grinding disc 55. The slag collection mechanism 7 includes an air extractor 71, which is used to extract chips from the grinding equipment. The central control mechanism 3 contains multiple control modules, which can control the moving mechanism 2, the clamping mechanism 4, the grinding mechanism 5, the cooling mechanism 6, and the slag collection mechanism 7, respectively.

[0038] Specifically, the slag guide groove 554 is an arc-shaped groove, and the arc direction of the slag guide groove 554 is the same as the rotation direction of the grinding disc 55. When grinding the mold, the chips generated by the mold will enter the slag guide groove 554 and then be sucked away by the slag collection mechanism 7.

[0039] In addition, when grinding the mold, the cooling mechanism 6 generates cooling gas and introduces the cooling gas into the cooling chamber 551 to cool the grinding disc 55, preventing the grinding disc 55 from getting too hot. This ensures that the grinding disc 55 can maintain a low temperature when it rubs against the mold being ground, preventing the mold from deforming or being damaged.

[0040] like Figures 1 to 4 As shown, the grinding mechanism 5 includes a movable block 51, which is welded to the slider 22. A connecting post 52 is integrally formed on the movable block 51, and a fixed block 53 is welded to the end of the connecting post 52 away from the movable block 51. A second bearing 532 is embedded in the fixed block 53, and a rotating tube 54 is interference-fitted onto the inner ring of the second bearing 532. A second motor 531 is mounted on the fixed block 53, and a first gear 5311 is welded to the rotating rod of the second motor 531. A second gear 541 that matches the first gear 5311 is welded to the rotating tube 54.

[0041] Specifically, when grinding the mold, the second motor 531 starts, and the rotating tube 54 rotates through the meshing of the first gear 5311 and the second gear 541.

[0042] like Figure 6 and Figure 7 As shown, to facilitate the installation and removal of the grinding disc 55, a locking groove 553 is provided on the grinding disc 55. A limit block 542 is integrally formed on the rotating tube 54, and a locking nut 56 is threaded onto the rotating tube 54. Specifically, the grinding disc 55 is installed between the locking nut 56 and the limit block 542 and is clamped by the locking nut 56 and the limit block 542. It is worth noting that the thickness of the locking nut 56 is less than the depth of the locking groove 553 to prevent the locking nut 56 from contacting the mold and to ensure the grinding effect of the grinding disc 55.

[0043] like Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, in order to cool the grinding disc 55 while grinding the mold, a first air supply pipe 62 is installed on the cooling tank 61. A first quick connector 63 is installed at the end of the first air supply pipe 62 away from the cooling tank 61. A first mounting groove 511 matching the first quick connector 63 is opened on the moving block 51, and the first quick connector 63 is threaded into the first mounting groove 511. The cooling mechanism 6 also includes a second air supply pipe 64, which is rotatably connected to the moving block 51 and communicates with the first mounting groove 511. The end of the second air supply pipe 64 away from the moving block 51 extends into the rotating tube 54 and is sealed to the rotating tube 54. A vent 641 is opened at the end of the second air supply pipe 64 that extends into the rotating tube 54. The vent 641 passes through the rotating tube 54 and the grinding disc 55, and communicates with the cooling chamber 551.

[0044] Specifically, the moving block 51 is embedded with a first bearing 514, and the outer wall of the second air supply pipe 64 is interference-fitted onto the rotating inner ring of the first bearing 514. During mold grinding, the rotating pipe 54 drives the grinding disc 55 and the second air supply pipe 64 to rotate together. The cooling tank 61 supplies cold air to the second air supply pipe 64 through the first air supply pipe 62, the first quick connector 63, and the first mounting groove 511. The cold air in the second air supply pipe 64 then enters the grinding disc 55 through the vent 641, cooling the grinding disc 55. The low temperature of the grinding disc 55 when in contact with the mold prevents overheating and deformation, ensuring grinding accuracy.

[0045] In addition, the grinding disc 55 is provided with an exhaust hole 555, which is connected to the cooling chamber 551. This prevents the grinding disc 55 from being damaged due to increased air pressure inside the grinding disc 55. At the same time, the grinding surface of the grinding disc 55 is also provided with multiple small holes, through which cooling gas can be sprayed onto the mold, further reducing the temperature of the mold and protecting it.

[0046] like Figures 2 to 9As shown, in order to remove chips while grinding the mold, a first suction pipe 72 is installed on the suction machine 71. A second quick connector 73 is installed at the end of the first suction pipe 72 away from the suction machine 71. A second mounting groove 512 matching the second quick connector 73 is opened on the moving block 51, and the second quick connector 73 is threaded into the second mounting groove 512. A connecting groove 513 is opened on the groove wall of the second mounting groove 512, which connects the second mounting groove 512 and the first mounting groove 511. The slag collection mechanism 7 also includes a second suction pipe 74, which is threaded into the connecting groove 513. The end of the second suction pipe 74 away from the moving block 51 passes through the second air supply pipe 64 and the rotating pipe 54, and the end of the second suction pipe 74 away from the connecting groove 513 is connected to the locking groove 553.

[0047] Specifically, the slag guide groove 554 and the locking groove 553 are connected. The outer diameter of the second suction pipe 74 is smaller than the inner diameter of the second air supply pipe 64, and the second suction pipe 74 is located inside the second air supply pipe 64. When grinding the mold, the air extractor 71 starts to generate suction. Because one end of the second suction pipe 74 is located inside the locking groove 553, the air in the slag guide groove 554 and the air in the locking groove 553 will enter the second suction pipe 74 and be sucked away by the air extractor 71. The airflow can also suck away the chips generated during grinding, preventing the chips from floating in the air. This not only protects the health of the workers but also prevents the chips from entering the grinding equipment.

[0048] It is worth noting that, in order to ensure the suction capacity of the vacuum pump 71, the end of the second vacuum pipe 74 away from the connecting groove 513 is recessed into the grinding surface of the grinding disc 55. During grinding, the second vacuum pipe 74 will not be blocked by the mold.

[0049] like Figure 1 and Figure 2 As shown, a working platform 11 is integrally formed inside the machine body 1. A through groove matching the second hydraulic pump 42 is opened on the working platform 11. A fixing column 43 matching the second hydraulic pump 42 is welded on the telescopic rod of the first hydraulic pump 41. Both the fixing column 43 and the second hydraulic pump 42 include elastic sleeves.

[0050] Specifically, when clamping the mold, the first hydraulic pump 41 starts and pushes the second hydraulic pump 42 upward. When the fixing column 43 blocks the through groove on the working platform 11, the first hydraulic pump 41 stops moving, and the second hydraulic pump 42 starts clamping the mold. Because of the blocking effect of the fixing column 43, the chips are further protected, preventing them from entering the clamping mechanism 4 and protecting the equipment.

[0051] Furthermore, the clamping mechanism 4 also includes a first motor 44, on which a placement plate 45 is welded. When the grinding position needs to be adjusted, the first motor 44 can control the rotation of the placement plate 45, which is convenient for adjusting the mold.

[0052] A mold polishing method, comprising the following steps, using mold polishing equipment to polish the mold:

[0053] S1. Place the mold to be polished in the mold polishing equipment;

[0054] S2. Start the central control mechanism 3. The central control mechanism 3 controls the clamping mechanism 4 to clamp the mold. The moving mechanism 2 drives the grinding mechanism 5 to move inside the machine body 1 to grind the mold. When the grinding mechanism 5 grinds the mold, the cooling mechanism 6 and the slag collection mechanism 7 execute the instructions issued by the central control mechanism 3. The slag collection mechanism 7 removes the production line chips during the mold grinding. The cooling mechanism 6 cools down the grinding disc 55 on the grinding mechanism 5.

[0055] In use, the mold grinding equipment is started, and the clamping mechanism 4 clamps the mold to be ground. At this time, the grinding disc 55 rotates to grind the mold. While the grinding disc 55 is grinding the mold, the cooling mechanism 6 introduces cooling gas into the cooling chamber 551 to cool the grinding disc 55 and prevent thermal deformation of the mold. At the same time, the slag collection mechanism 7 starts to extract air and discharge the chips generated during grinding into the collection device to protect the personnel and equipment.

[0056] Compared with the prior art, the mold grinding equipment and grinding method of the present invention can remove chips in real time, which not only protects the health of the workers, but also avoids the impact of chips on the grinding equipment and ensures the normal operation of the equipment. In addition, the grinding disc can be cooled during grinding, which effectively prevents molds with low melting points from deforming or softening during the grinding process, thereby ensuring the quality of the mold.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
