[0036] Please refer to the appendix carefully. Figure 1 , 2As shown in Figures 3 and 6, in a preferred embodiment of the present invention, a vertical injection molding machine with a self-lubricating mechanism includes a base housing 10. The top of the base housing 10 is provided with an annular outer cover box 11. The inner wall of the annular outer cover box 11 is rotatably connected to a disc 12. The bottom of the disc 12 is provided with an extension tube 13. The bottom end of the extension tube 13 is provided with a toothed wall ring 14. The inner wall of the base housing 10 is provided with a stepper motor 15. The actuating end of the stepper motor 15 is provided with a drive gear 16 that meshes with the toothed wall ring 14. The bottom of the inner wall of the base housing 10 is provided with a first hydraulic cylinder 17 whose actuating end passes through the disc 12 and extends above the disc 12. The outer wall of the base housing 10 is provided with a second hydraulic cylinder 18. The actuating ends of both the first hydraulic cylinder 17 and the second hydraulic cylinder 18 are connected to the bottom of the frame 19.

[0037] It should be noted that in this embodiment, during mold injection, two lower molds are fixed on the disc 12 and the upper mold is fixed on the frame 19. When one of the lower molds is directly below the upper mold, the actuators of the first hydraulic cylinder 17 and the second hydraulic cylinder 18 drive the frame 19 to move downward for mold closing, injection, and cooling. After completion, the actuators of the first hydraulic cylinder 17 and the second hydraulic cylinder 18 drive the frame 19 to move upward to open the mold. At this time, the disc 12 rotates 180 degrees so that the positions of the lower mold that has been injected and the lower mold that has not been injected are swapped, so that injection can be performed again. At this time, the mold lubrication device 30 can lubricate the guide sleeve of the lower mold that has been injected.

[0038] Furthermore, when the disc 12 rotates, the stepper motor 15 drives the drive gear 16 to rotate, and the drive gear 16 drives the extension tube 13 and the disc 12 to rotate through the toothed ring 14.

[0039] Please refer to the appendix carefully. Figure 2 , 3As shown in Figures 5, 6, and 7, in another preferred embodiment of the present invention, the upper and lower surfaces of the disc 12 are respectively provided with a first outer cover tube 20 and a second outer cover tube 21 sleeved on the outer wall of the actuating end of the first hydraulic cylinder 17. The upper surface of the disc 12 is provided with an oil spraying component 22 for conveying lubricating oil into the first outer cover tube 20. The side wall of the extension tube 13 is provided with an oil spraying component 23 for drawing oil from the second outer cover tube 21 and discharging it to the toothed ring 14. The top of the annular outer cover box 11 is provided with an actuating end connected to the top of the annular outer cover box 11. The oil spraying component 24 has an inner wall of the base housing 10 for recovering the oil from the spraying component 23 and the oil discharged from the oil spraying component 24. The oil spraying component 22 includes a first oil storage tank 221 disposed on the upper surface of the disc 12, a transmission oil pipe 222 with one end connected to the outer wall of the first oil storage tank 221 and the other end connected to the outer wall of the first outer cover pipe 20, a shaft pipe 223 passing through the disc 12 and sleeved on the outer wall of the actuating end of the first hydraulic cylinder 17, and a plurality of oil holes 224 passing through the shaft pipe 223. The oiling component 23 includes a miniature oil pump 231 located at the bottom of the disc 12 and connected to the second outer casing pipe 21 via a pipe; an oil box 232 located on the outer wall of the extension pipe 13 and connected to the miniature oil pump 231 via a pipe; an oil spray pipe 233 connected to the bottom of the oil box 232; and an electrically controlled valve 234 located on the outer wall of the oil spray pipe 233. The oil spraying component 24 includes an arc-shaped box 241 located at the top of the annular outer casing 11, and multiple leaks passing through the top of the annular outer casing 11 and located inside the arc-shaped box 241. The second oil storage tank 243 is symmetrically arranged on the outer wall of the annular outer casing 11 and connected to the arc-shaped box 241 through a pipe. The bottom of the second oil storage tank 243 is provided with a pressure pump 244. The recovery component 25 includes a first recovery ring 251 located on the inner wall of the base housing 10 and below the disc 12, a second recovery ring 252 located on the inner wall of the base housing 10 and below the toothed ring 14, and a recovery pipe 253 connecting the bottom of the first recovery ring 251 and the second recovery ring 252.

[0040] It should be noted that in this embodiment, the oil spraying component 22 facilitates the spraying of lubricating oil into the first outer cover tube 20, so as to reduce the wear between the actuator end of the first hydraulic cylinder 17 and the disc 12. When the oil spraying component 22 is working, the valve of the first oil storage tank 221 is opened, and the oil enters the first outer cover tube 20 through the transmission oil pipe 222, and enters the inner wall of the shaft tube 223 through the oil hole 224. The lubricating oil finally falls into the second outer cover tube 21.

[0041] Furthermore, the oil-spraying component 23 facilitates the extraction of oil from the second outer casing tube 21 and discharges it to the toothed wall ring 14. When the oil-spraying component 23 is working, the micro oil pump 231 draws in the lubricating oil from the second outer casing tube 21 and discharges it into the oil box 232. When the disc 12 rotates, the electric control valve 234 opens, and the oil drips onto the toothed wall ring 14.

[0042] Furthermore, the oil spraying component 24 facilitates the spraying of oil into the annular outer casing 11 to ensure the stable rotation of the disc 12. When the oil spraying component 24 is working, the valve of the second oil storage tank 243 is opened, and the pressure pump 244 pressurizes the second oil storage tank 243. The lubricating oil enters the arc-shaped box 241 through the pipeline and enters the annular outer casing 11 through the leakage hole 242.

[0043] Furthermore, when the recovery component 25 is working, the lubricating oil dripping from the gap between the disc 12 and the annular outer casing 11 enters the first recovery ring 251, and the lubricating oil dripping from the toothed wall ring 14 enters the second recovery ring 252. The recovery pipe 253 can be connected to a negative pressure source, and the recovery pipe 253 performs negative suction recovery of the lubricating oil in the first recovery ring 251 and the second recovery ring 252.

[0044] Please refer to the appendix carefully. Figure 2 , 4As shown in Figures 7 and 8, in another preferred embodiment of the present invention, a mold lubrication device 30 is provided on the upper surface of the annular outer cover box 11 and on the side away from the frame 19. The mold lubrication device 30 includes a lifting component 31 on the top of the annular outer cover box 11, a lifting plate 32 on the actuating end of the lifting component 31, a plurality of storage boxes 33 on the top of the lifting plate 32, a positioning component 34 on the bottom, an oil component 35 on the actuating end of the positioning component 34, and an oil rope lubrication component 36 on the bottom of the oil component 35. The lifting component 31 includes a drive cylinder 311 on the upper surface of the annular outer cover box 11, and the actuating end of the drive cylinder 311 is connected to the bottom of the lifting plate 32. The positioning component 34 includes two first bidirectional linear guide rails 341 symmetrically arranged on the bottom of the lifting plate 32, and two ends respectively connected to the two first bidirectional linear guide rails. The two second bidirectional linear guides 342 at the execution end of the 341 are provided. The oil component 35 includes a positioning oil pipe 351 located at the execution end of the second bidirectional linear guide 342, and a third oil storage tank 352 located on the upper surface of the lifting plate 32 and connected to multiple positioning oil pipes 351 through a pipe. The oil rope lubrication component 36 includes a connecting pipe 361 with its top end located on the inner wall of the positioning oil pipe 351, an oil guide column 362 connected to the inner wall of the connecting pipe 361 by multiple support columns on the top of the side wall, an oil guide rope 363 located on the outer wall of the oil guide column 362 and in a spiral shape, and a sponge pad 364 located on the top of the oil guide column 362 and located in the connecting pipe 361. One of the storage boxes 33 is provided with multiple guide sleeve cleaning components 37. The guide sleeve cleaning component 37 includes a threaded pipe 371 located in the storage box 33 and a cleaning column 372 located at the bottom end of the threaded pipe 371.

[0045] It should be noted that in this embodiment, when the guide sleeve needs to be lubricated, the connecting pipe 361 is threaded to the inner wall of the positioning oil pipe 351, and the oil rope lubrication component 36 is positioned to the location of the guide sleeve by the positioning component 34. The third oil storage tank 352 delivers lubricating fluid to the positioning oil pipe 351 through the pipeline. The lubricating fluid wets the sponge pad 364 and the oil guide rope 363. At this time, the drive cylinder 311 drives the lifting plate 32 to descend so that the oil guide column 362 is inserted into the guide sleeve to lubricate the inner wall of the guide sleeve.

[0046] When it is necessary to clean the inner wall of the guide sleeve, the threaded pipe 371 is threaded to the inner wall of the positioning oil pipe 351, and the guide sleeve cleaning component 37 is positioned to the guide sleeve position by the positioning component 34. At this time, the drive cylinder 311 drives the lifting plate 32 to descend so that the cleaning column 372 is inserted into the guide sleeve to clean the inner wall of the guide sleeve.

[0047] Furthermore, when the positioning component 34 is working, the actuator of the first bidirectional linear guide 341 drives the two second bidirectional linear guides 342 to move away from each other, and the actuator of the second bidirectional linear guides 342 drives the two oil rope lubrication components 36 to move away from each other.

[0048] The specific process of this invention is as follows:

[0049] During mold injection, two lower molds are fixed on the disc 12 and the upper mold is fixed on the frame 19. When one of the lower molds is directly below the upper mold, the actuators of the first hydraulic cylinder 17 and the second hydraulic cylinder 18 drive the frame 19 to move downward for mold closing, injection, and cooling. After completion, the actuators of the first hydraulic cylinder 17 and the second hydraulic cylinder 18 drive the frame 19 to move upward to open the mold. At this time, the disc 12 rotates 180 degrees so that the position of the lower mold that has been injected and the lower mold that has not been injected are swapped, and injection can be performed again. At this time, the mold lubrication device 30 can lubricate the guide sleeve of the lower mold that has been injected.

[0050] When the disc 12 rotates, the stepper motor 15 drives the drive gear 16 to rotate, and the drive gear 16 drives the extension tube 13 and the disc 12 to rotate through the toothed ring 14.

[0051] The oil spraying component 22 facilitates the spraying of lubricating oil into the first outer cover tube 20, so as to reduce the wear between the actuator end of the first hydraulic cylinder 17 and the disc 12. When the oil spraying component 22 is working, the valve of the first oil storage tank 221 is opened, and the oil enters the first outer cover tube 20 through the transmission oil pipe 222, and enters the inner wall of the shaft tube 223 through the oil hole 224. The lubricating oil finally falls into the second outer cover tube 21.

[0052] The oil spraying component 23 facilitates the extraction of oil from the second outer casing tube 21 and discharges it to the toothed wall ring 14. When the oil spraying component 23 is working, the micro oil pump 231 draws in the lubricating oil from the second outer casing tube 21 and discharges it into the oil box 232. When the disc 12 rotates, the electric control valve 234 opens and the oil drips onto the toothed wall ring 14.

[0053] The oil spraying component 24 facilitates the spraying of oil into the annular outer cover box 11 to ensure the stable rotation of the disc 12. When the oil spraying component 24 is working, the valve of the second oil storage tank 243 is opened, and the pressure pump 244 pressurizes the second oil storage tank 243. The lubricating oil enters the arc-shaped box 241 through the pipeline and enters the annular outer cover box 11 through the leakage hole 242.

[0054] When the recovery component 25 is working, the lubricating oil dripping from the gap between the disc 12 and the annular outer cover box 11 enters the first recovery ring 251, and the lubricating oil dripping from the toothed wall ring 14 enters the second recovery ring 252. The recovery pipe 253 can be connected to a negative pressure source, and the recovery pipe 253 performs negative suction recovery of the lubricating oil in the first recovery ring 251 and the second recovery ring 252.

[0055] When the guide sleeve needs to be lubricated, the connecting pipe 361 is threaded to the inner wall of the positioning oil pipe 351. The oil rope lubrication component 36 is positioned to the guide sleeve position by the positioning component 34. The third oil storage tank 352 delivers lubricating fluid to the positioning oil pipe 351 through the pipeline. The lubricating fluid wets the sponge pad 364 and the oil guide rope 363. At this time, the drive cylinder 311 drives the lifting plate 32 to descend so that the oil guide column 362 is inserted into the guide sleeve to lubricate the inner wall of the guide sleeve.

[0056] When it is necessary to clean the inner wall of the guide sleeve, the threaded pipe 371 is threaded to the inner wall of the positioning oil pipe 351, and the guide sleeve cleaning component 37 is positioned to the guide sleeve position by the positioning component 34. At this time, the drive cylinder 311 drives the lifting plate 32 to descend so that the cleaning column 372 is inserted into the guide sleeve to clean the inner wall of the guide sleeve.

[0057] When the positioning component 34 is working, the actuator of the first bidirectional linear guide 341 drives the two second bidirectional linear guides 342 to move away from each other, and the actuator of the second bidirectional linear guides 342 drives the two oil rope lubrication components 36 to move away from each other.
