The end of the liquid guide pipe 18 away from the liquid storage tank 13 extends to the inner cavity of the mounting ring 11.

[0030] In this design, the lower die holder 1 can be fixedly installed on the punch press with screws. The user can use the punch press to directly act on the top of the upper die holder 2, pushing the upper die holder 2 downward. When the upper die holder 2 moves downward, a pair of outer guide pillars 6 will pass through the outer guide sleeve 7 and slide inside the outer guide sleeve 7. The setting of a pair of outer guide pillars 6 and outer guide sleeve 7 can limit the movement trajectory of the upper die holder 2, ensuring that the upper die holder 2 moves downward smoothly, so that the lower module 3 and the upper module 4 can be correctly connected and the mold closing can be completed smoothly. During the downward movement of the upper die holder 2, a pair of support pillars 8 will also drive through the lower die holder 1 and compress the first spring 9. The main function of the first spring 9 is to help the upper die holder 2 reset. When the workpiece is finished, the punch press moves upward and disengages from the upper die holder 2. At this time, the first spring 9 will push the upper die holder 2 upward to reset.

A baffle 15 is slidably connected to the top of the mounting ring 11. The bottom end of the baffle 15 extends into the inner cavity of the mounting ring 11. The baffle 15 abuts against one end of the liquid guide tube 18. A through hole 16 matching the liquid guide tube 18 is opened on the upper part of the baffle 15. A second spring 17 is provided on the lower side of the baffle 15. The two ends of the second spring 17 are fixedly connected to the inner wall of the baffle 15 and the liquid storage tank 13, respectively. A squeezing block 10 is fixedly connected to the outer end of the outer guide post 6.

[0034] In each time of the mold, the outer guide column 6 will be through the outer guide sleeve 7, and when the lower module 3 and the upper module 4 are closed, the extrusion block 10 at the outer end of the outer guide column 6 will also extrude to the baffle 15, the liquid tank 13 is filled with lubricant, under the action of gravity, the lubricant should flow into the inner cavity of the mounting ring 11 through the liquid guide pipe 18, but it is blocked by the baffle 15, the lubricant cannot flow in, once the extrusion block 10 extrudes the baffle 15 downward, it will force the baffle 15 to slide downward and extrude the second spring 17, when the through hole 16 coincides with the liquid guide pipe 18, the lubricant in the liquid guide pipe 18 will flow into the inner cavity of the liquid tank 13 through the through hole 16, and fill the inner cavity of the liquid tank 13 during the closing of the lower module 3 and the upper module 4, so the setting, when the lower module 3 and the upper module 4 are opened, the outer guide column 6 moves upward, the extrusion block 10 is separated from the baffle 15, the baffle 15 will reset under the elastic force of the second spring 17, and reseal the liquid guide pipe 18, and when the outer guide column 6 moves upward, it will drive the plurality of balls 14 to roll at the outer end thereof, the balls 14 will take out the lubricant in the liquid tank 13 when rolling, and smear on the surface of the outer guide column 6, so as to achieve the purpose of reducing the friction between the outer guide column 6 and the outer guide sleeve 7 during the next closing and opening.
