DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a CNC engraving and milling machine for mold production, comprising a hollow base 1, a workbench 11 and a blocking frame 12 are fixedly installed on the top of the hollow base 1, a water leakage hole 13 is opened on the top of the hollow base 1, and the water leakage hole 13 is opened between the workbench 11 and the blocking frame 12, so that the coolant can be recovered, an engraving and milling mechanism 2 is installed on the upper side of the hollow base 1, a cooling component 3 is installed on one side of the hollow base 1, and the cooling component 3 includes a water pump 31, and the water pump 31 is installed on one side of the top of the hollow base 1, one end of the water pump 31 is connected to a water suction pipe 32, and the bottom end of the water suction pipe 32 extends to the inner lower side of the hollow base 1, the other end of the water suction pipe 32 is connected to a water outlet pipe 33, and a nozzle 34 is installed on the upper opening of the water outlet pipe 33, this structure makes it possible to spray coolant when engraving and milling the mold to cool it down, so that the engraving and milling can be better performed.

[0023] As an implementation method in this embodiment, Figure 4 As shown, a filter assembly 4 is installed on the lower side of the hollow base 1, and the filter assembly 4 includes a mounting frame 41, a through hole 43 and a guide groove 45. A filter screen 42 is embedded and installed on the surface of the mounting frame 41. The through hole 43 is opened at one end of the hollow base 1. The mounting frame 41 is inserted into the hollow base 1 through the through hole 43. Guide rods 44 are connected to both sides of the outer wall of the filter screen 42. The guide groove 45 is opened on both sides of the inner wall of the hollow base 1. The guide rod 44 is inserted into the guide groove 45. This structure makes it possible to recover the coolant. Filtering is performed so that the filtered coolant can be reused. A handle 46 is installed at the outer end of the installation frame 41, which makes it more convenient to push the installation frame 41. The inner wall of the hollow base 1 is connected to the side close to the water suction pipe 32. The bottom end of the water suction pipe 32 extends to the bottom of the hollow base 1 through the inclined plate 14. The inner end of the installation frame 41 is abutted against the inclined plate 14, so that the gap between the installation frame 41 and the inner wall can be blocked, and the recovered coolant can be directed to the filter screen 42 for filtration.

[0024] It should be noted that a connecting pipe is installed on the lower side of the outer wall of the hollow base 1, and the connecting pipe is equipped with a valve, so that coolant can be input into the hollow base 1 through the connecting pipe, and coolant that can no longer be used in the hollow base 1 can also be discharged.

[0025] As an implementation method in this embodiment, Figure 3 and Figure 5As shown, a cleaning mechanism for preventing the leakage hole 13 from being blocked is installed on the lower side of the blocking frame 12. The cleaning mechanism includes a cleaning component 5 for cleaning the leakage hole 13 and a driving component 6 for driving the cleaning component 5 to rotate. The cleaning component 5 includes a fixed plate 51, and the fixed plate 51 is rotatably installed in the blocking frame 12 through the driving component 6. A slide groove 52 is provided at the bottom end of the fixed plate 51, and a spring 53 is installed on the upper side of the slide groove 52. A scraper 54 is slidably installed on the lower side of the slide groove 52. The two ends of the spring 53 are respectively fixedly connected to the top of the inner wall of the slide groove 52 and the top of the scraper 54. This structure makes it possible to clean the leakage hole 13 in time, reduce the possibility of the leakage hole 13 being blocked, and make the recovery of the coolant smoother. In addition, the spring 53 can push the scraper 54 downward, so that after the scraper 54 is worn, it can also be adjusted in time, so as to better keep the bottom end of the scraper 54 in contact with the top of the hollow base 1, thereby greatly increasing the cleaning effect. The driving assembly 6 includes a connecting block 61, and the connecting block 61 is connected to the lower side of the outer wall of the blocking frame 12. A mounting groove 62 is provided in the connecting block 61. A motor 63 is installed at the top of the connecting block 61, and the output end of the motor 63 extends to the mounting groove 62 and is connected to a gear 64. A movable groove 65 is provided on the inner wall of the blocking frame 12, and a gear ring 66 is rotatably installed in the movable groove 65. The movable groove 65 is communicated with the mounting groove 62, and the gear ring 66 is meshed with the gear 64. One end of the fixed plate 51 is fixedly connected to the inner wall of the gear ring 66. This structure makes it possible to drive the scraper 54 to rotate by driving the fixed plate 51, thereby realizing the cleaning of the water leakage hole 13, which greatly increases the practicality of the device. The fixed plate 51 is rotatably installed between the workbench 11 and the blocking frame 12. A limiting ring 15 is rotatably provided on the lower side of the workbench 11. The end of the fixed plate 51 away from the gear ring 66 is fixedly connected to the outer wall of the limiting ring 15. This structure makes the rotation of the fixed plate 51 more stable.

[0026] It should be noted that the top of the workbench 11 is higher than the top of the fixed plate 51, so that the fixed plate 51 will not affect the engraving and milling of the mold placed on the workbench 11 when rotating, so that cleaning can be performed while engraving and milling.

[0027] Working principle: If the mold needs to be engraved and milled, just place the mold on the workbench 11 in the blocking frame 12, and then use the engraving and milling mechanism 2 to engrave and mill the mold. At this time, the water pump 31 can be started to input the coolant of the hollow base 1 into the water inlet and outlet pipes 33 through the water suction pipe 32, and finally spray it out from the nozzle 34. In this way, the temperature can be reduced while engraving and milling, and the sprayed coolant will return to the hollow base 1 through the leakage hole 13. At the same time, the motor 63 is started, and the motor 63 drives the gear 64 to rotate. Through meshing, the gear 64 drives the gear ring 66 to rotate. At this time, the gear ring 66 can drive the fixed plate 51 to rotate, and the fixed plate 51 will The scraper 54 is driven to rotate to clean the water leakage hole 13, and the water leakage hole 13 is better prevented from being blocked by metal scraps. At this time, the fixed plate 51 will also drive the limit ring 15 to rotate, so that the coolant and some metal scraps can more easily enter the hollow base 1 through the water leakage hole 13, which greatly increases the practicality of the device. If the scraper 54 is rotated for a long time for cleaning, the scraper 54 will be worn. At this time, the scraper 54 will be pushed downward by the restoring force of the spring 53, so that the scraper 54 slides in the slide groove 52 until the bottom end of the scraper 54 is again in contact with the top of the hollow base 1, which greatly increases the cleaning effect of the device;

[0028] In addition, when the coolant and some metal scraps enter the hollow base 1 through the leakage hole 13, they will first fall on the filter screen 42 for filtration. The filtered coolant is cleaner and easier to reuse. If the suction pipe 32 needs to be cleaned, just hold the handle 46 and pull it outward, so that the handle 46 drives the installation frame 41, and the installation frame 41 drives the filter screen 42. At the same time, the installation frame 41 drives the guide rod 44 to slide in the guide groove 45 until the installation frame 41 is completely removed from the through hole 43. In this way, the filter screen 42 can be disassembled, which makes it easier to clean the filter screen 42, greatly increasing the convenience of the device.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
