Detailed Implementation

[0087] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0088] Example 1

[0089] A lathe for machining the preform of a graphite mold, such as Figures 1-6As shown, the assembly includes a base 1, a first support 2, a rotary cylinder 3, a first gear 4, a guide rail 5, a first rack 6, a telescopic frame 7, a grinding machine 8, a first spring 9, a first protective cover 10, a transmission mechanism 11, a demagnetizing and polishing device 12, and a clamping assembly 13. The base 1 has a first support 2 located in the lower middle of both its front and rear sides. A rotary cylinder 3 is located between the upper inner sides of the first support 2. A first gear 4 is mounted on the output shaft of the rotary cylinder 3. Guide rails 5 are symmetrically arranged between the upper inner sides of the first support 2. On the lower side of the rotary cylinder 3, a first rack 6 is slidably provided on the guide rail 5. The first rack 6 meshes with the first gear 4. A telescopic frame 7 is provided on the outer side of the first rack 6. A grinding machine 8 is provided at the bottom of the telescopic frame 7. A first spring 9 is provided inside the telescopic frame 7. A first protective cover 10 is provided in the middle of the upper side of the base 1. A transmission mechanism 11 is provided on the upper part of the base 1. A demagnetizing polishing device 12 is provided on the upper right side of the base 1. A pressing assembly 13 is provided on the upper right side of the base 1. The pressing assembly 13 is located outside the demagnetizing polishing device 12.

[0090] The transmission mechanism 11 includes a motor 1101, a lead screw 1102, a mold placement table 1103, pulleys 1104, and a flat belt 1105. The lead screw 1102 is symmetrically rotated on the upper part of the base 1. The motor 1101 is located on the upper left front side of the base 1. The left side of the lead screw 1102 is connected to the output shaft of the motor 1101. The mold placement table 1103 is threaded between the lead screws 1102. The pulleys 1104 are located on the left side of the lead screws 1102. A flat belt 1105 is wound between the pulleys 1104.

[0091] The demagnetizing and polishing device 12 includes a heating tube 1201, a first rotating block 1202, a second rotating block 1203, a second protective cover 1204, a polishing machine 1205, a grinding wheel 1206, and a tightening nut 1207. The heating tube 1201 is located on the upper right side of the base 1. The first rotating block 1202 is symmetrically rotated on the upper right side of the base 1. The first rotating block 1202 is located to the right of the heating tube 1201. The second rotating block 1203 is rotatably mounted on the upper part of the first rotating block 1202. The second protective cover 1204 is rotatably mounted on the upper part of the second rotating block 1203. The polishing machine 1205 is located in front of the second protective cover 1204. The grinding wheel 1206 is mounted on the output shaft of the polishing machine 1205. The grinding wheel 1206 is rotatably connected to the second protective cover 1204. The tightening nut 1207 is threaded between the first rotating block 1202 and the second rotating block 1203 on the same side.

[0092] The clamping assembly 13 includes a first guide rod 1301, a second spring 1302, and a fixing block 1303. The fixing block 1303 is rotatably provided on the outer center of the first rotating block 1202. The first guide rod 1301 is slidably provided on the fixing block 1303. The upper part of the first guide rod 1301 is connected to the second rotating block 1203 on the same side. The second spring 1302 is wound around the first guide rod 1301. The two ends of the second spring 1302 are respectively connected to the fixing block 1303 and the second rotating block 1203.

[0093] When processing a graphite mold, the mold is first placed on the mold-laying table 1103. Then, according to the height of the mold, the tightening nut 1207 is rotated to loosen the first rotating block 1202 and the second rotating block 1203. Next, the second protective cover 1204 is moved up and down, causing the polishing machine 1205 and the grinding wheel 1206 to move up and down. The second spring 1302 deforms adaptively. After the position of the grinding wheel 1206 is adjusted, the tightening nut 1207 is reversed to fix it in place. Position the grinding wheel 1206, then start the motor 1101, heating element 1201, rotary cylinder 3, grinding machine 8, and polishing machine 1205. The polishing machine 1205 drives the grinding wheel 1206 to rotate, controlling the motor 1101 to rotate forward. The motor 1101 drives the lead screw 1102, pulley 1104, and flat belt 1105 to rotate forward, thereby driving the mold placement table 1103 to move to the right. The mold placement table 1103 drives the mold to move to the right. At the same time, the output shaft of the rotary cylinder 3 drives the first gear 4 intermittently. The forward and reverse rotation of the grinding wheel causes the first rack 6, telescopic frame 7, and grinding machine 8 to reciprocate. When the grinding machine 8 contacts the mold, it grinds the mold. The first spring 9 is compressed adaptively according to the height of the mold, ensuring that the grinding machine 8 remains in contact with the mold. When the grinding machine 8 separates from the mold, the first spring 9 returns to its original state, causing the grinding machine 8 to reset. When the mold approaches the heating tube 1201, the heating tube 1201 heats and demagnetizes the mold. When the grinding wheel 120... When the grinding wheel 1206 comes into contact with the mold, it polishes the mold. When the grinding wheel 1206 separates from the mold, the polished mold is removed manually. Then the heating tube 1201, rotary cylinder 3, grinding machine 8 and polishing machine 1205 are turned off. Then the motor 1101 is controlled to reverse, which drives the lead screw 1102, pulley 1104 and flat belt 1105 to reverse, which in turn drives the mold release table 1103 to move to the left to reset. When people need to process other molds, the above operation can be repeated.

[0094] Example 2

[0095] Based on Example 1, such as Figure 1 , Figure 7 and Figure 8As shown, it also includes a mold clamping mechanism 14, which includes a pulling frame 1401, a mounting block 1402, a clamping block 1403, a guide rail 1404, and a connecting rod 1405. The guide rail 1404 is provided in the middle of the upper part of the base 1. The pulling frame 1401 is slidably provided on the left side of the guide rail 1404. The pulling frame 1401 is slidably connected to the middle of the mold placement table 1103. The bottom left and right sides of the mold placement table 1103 are symmetrically provided with mounting blocks 1402, and the number of mounting blocks 1402 is 8. A clamping block 1403 is rotatably provided between two mounting blocks 1402 on the same side. Two connecting rods 1405 are rotatably provided on the front and rear sides of the upper part of the pulling frame 1401. The outer ends of the connecting rods 1405 are slidably engaged with the clamping blocks 1403 on the same side.

[0096] When the mold placement table 1103 moves to the right, it drives all its components to move to the right, causing the pulling frame 1401 to slide to the right within the guide rail 1404. Under the guidance of the guide rail 1404, the pulling frame 1401 first moves downward. The pulling frame 1401 drives the locking block 1403 to rotate inward through the connecting rod 1405, causing the locking block 1403 to clamp the mold. After the mold polishing is completed, the guide rail 1404 drives the pulling frame 1401 to move upward and reset. The pulling frame 1401 drives the locking block 1403 to move outward and reset through the connecting rod 1405, causing the locking block 1403 to release the mold. The polished mold can then be removed manually.

[0097] Example 3

[0098] Based on Example 2, such as Figure 1 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, it also includes a dust removal mechanism 15, which includes a water tank 1501, a third protective cover 1502, rollers 1503, a second bracket 1504, a water pump 1505, a water pipe 1506, a filter frame 1507, a collection frame 1508, and a nozzle 1509. The water tank 1501 is located in the middle of the lower part of the base 1. The third protective cover 1502 is provided on the inner side of the grinding machine 8. Rollers 1503 are rotatably provided on the upper outer side of the first bracket 2. The second bracket is located in the middle of the rear side of the bottom of the water tank 1501. 1504, a water pump 1505 is provided on the second bracket 1504, and water pipes 1506 are provided on both the front and rear sides of the water pump 1505. The upper ends of the water pipes 1506 are connected to the third protective cover 1502 on the same side. The water pipes 1506 all pass around the rollers 1503 on the same side. A filter frame 1507 is provided in the middle of the top of the water tank 1501. The top of the filter frame 1507 is connected to the bottom of the first protective cover 10. A collection frame 1508 is provided on the upper front side of the water tank 1501. Sprayers 1509 are provided at the bottom of the third protective cover 1502.

[0099] It also includes a separation mechanism 16, which includes a discharge plate 1601, a rotating plate 1602, a connecting rod 1603, a torsion spring 1604, and a contact plate 1605. The discharge plate 1601 is provided on the lower front side of the filter frame 1507, and the rotating plate 1602 is rotatably provided on the upper rear side of the filter frame 1507. The connecting rod 1603 is rotatably provided on both the left and right sides of the rotating plate 1602. The torsion spring 1604 is provided between the left and right sides of the rotating plate 1602 and the filter frame 1507. The contact plate 1605 is slidably provided on the lower inner side of the first protective cover 10. The contact plate 1605 cooperates with the pulling frame 1401. The upper part of the connecting rod 1603 is rotatably connected to the contact plate 1605.

[0100] Water can be added to the water tank 1501. When the grinding machine 8 grinds the mold, the water pipe 1506 moves according to the movement of the grinding machine 8. The roller 1503 plays an auxiliary role. At the same time, the water pump 1505 is started, which draws water from the water tank 1501 and then transmits the water through the water pipe 1506 to the third protective cover 1502, so that the water can be sprayed onto the mold through the nozzle 1509, thereby achieving the purpose of dust removal. Wastewater and waste chips will fall down onto the rotating plate 1602. At the same time, the pulling frame 1401 contacts the contact plate 1605, and the torsion spring 1604 acts as a trigger. The contact plate 1605 moves up and down repeatedly. The contact plate 1605 drives the rotating plate 1602 to rotate up and down through the connecting rod 1603. This causes the wastewater to fall into the water tank 1501 through the rotating plate 1602 and the filter frame 1507, where it can be recycled. The waste chips fall into the collection frame 1508 through the rotating plate 1602. When the grinding machine 8 separates from the mold, the water pump 1505 is turned off, the nozzle 1509 stops spraying water, and at the same time, the pull frame 1401 separates from the contact plate 1605, and the contact plate 1605 stops moving. Then, the waste chips in the collection frame 1508 can be manually removed.

[0101] It also includes a scraping mechanism 17, which includes a second rack 1701, a sliding block 1702, a second gear 1703, a guide frame 1704, a third spring 1705, a second guide rod 1706, a third rack 1707, a scraper 1708, and a fourth spring 1709. The lower outer side of the grinding machine 8 is provided with a second rack 1701, and the upper inner side of the first support 2 is provided with a guide frame 1704. A sliding block 1702 is slidably mounted on each guide frame 1704, and a second gear 1703 is rotatably mounted inside each sliding block 1702. The second gear 1703 interacts with the second rack 1701. 701 engagement, two third springs 1705 are provided between the sliding block 1702 and the guide frame 1704 on the same side, two second guide rods 1706 are provided on the lower part of the front and rear sides of the first protective cover 10, and a third rack 1707 is slidably provided between the lower parts of the second guide rods 1706 on the same side. The third rack 1707 meshes with the second gear 1703, and a scraper 1708 is slidably provided on the lower part of the third rack 1707. The scraper 1708 is in contact with the inner wall of the first protective cover 10, and two fourth springs 1709 are provided between the outer side of the scraper 1708 and the third rack 1707 on the same side.

[0102] Initially, the third spring 1705 is in a stretched state. When the grinding machine 8 reciprocates, it drives the second rack 1701 to reciprocate, thereby driving the second gear 1703 to rotate in both directions. This, in turn, drives the third rack 1707 and the scraper 1708 to move up and down. The fourth spring 1709 can adapt to the shape of the first protective cover 10, so that the scraper 1708 is always in contact with the inner wall of the first protective cover 10, thereby scraping away the waste stuck to the inner wall of the first protective cover 10. When the first spring 9 is adapted to the height of the mold, the third spring 1705 can adapt to return to its original shape, so that the second gear 1703 can always mesh with the second rack 1701. When the grinding machine 8 stops moving, the scraper 1708 also stops moving.
