Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0023] See also Figure 3 A pressure rod 403 is fixedly embedded in the upper end of the piston 402, and the pressure rod 403 passes through the sleeve 401. A cushion block 404 is fixedly sleeved on the upper end of the pressure rod 403, and a spring 405 is movably sleeved on the outer side of the pressure rod 403. The cushion block 404 can increase the contact area between the spring 405 and the pressure rod 403, and the two ends of the spring 405 are movably abutted against the sleeve 401 and the cushion block 404 respectively.

[0024] See also Figure 3 A conduit 1 406 is installed on the lower side of the sleeve 401, a conduit 2 407 is installed on the outer side of the sleeve 401, and a one-way valve 408 is fixedly installed between the conduit 1 406, the conduit 2 407 and the sleeve 401. The one-way valve 408 can limit the flow direction of the liquid in the conduit 1 406 and the conduit 2 407.

[0025] See also Figure 3An annular tube 409 is fixedly installed at one end of the conduit 406 away from the sleeve 401 and is interconnected with the conduit 1. A plurality of oil nozzles 410 equidistantly distributed in a circle are fixedly installed on the inner side of the annular tube 409. The oil nozzles 410 are embedded in the interior of the mold body 1, and the oil nozzles 410 and the annular tube 409 are interconnected.

[0026] The working principle of convenient and automatic replenishment of lubricating oil: when replenishing lubricating oil into the mold body 1, the punch head 2 drives the pressing block 501 to move downward, and the pressing block 501 moves downward to drive the piston 402 to move downward inside the sleeve 401 through the pressure rod 403. During the downward movement, the piston 402 can squeeze the lubricating oil inside the sleeve 401 into the mold body 1 through the conduit 1 406 and the annular tube 409, and can automatically replenish the lubricating oil into the mold body 1 to avoid affecting the processing progress of the washers. During the process of the punch head 2 driving the pressing block 501 to move upward, the piston 402 moves upward driven by the compression force of the spring 405. At this time, the conduit 2 407 inserted into the oil tank will suck the lubricating oil in the oil tank into the sleeve 401 for storage.

[0027] Embodiment 2

[0028] See also Figure 4 This embodiment further explains Example 1. The pressing assembly 5 includes a pressing block 501 that is in active contact with the punch head 2. The punch head 2 can drive the pressing assembly 5 to move up and down. The outer side of the pressing block 501 is movably sleeved with a guide rail 502, and the connection between the guide rail 502 and the punch head 2 is a fixed connection. The pressing block 501 can move on the inner side of the guide rail 502.

[0029] See also Figure 4 Two symmetrically distributed magnetic blocks 503 are movably embedded on the outer side of the pressing block 501, and the connection method between the magnetic blocks 503 and the guide rail 502 is active magnetic attraction. The magnetic blocks 503 can position the pressing block 501. A dial button 504 is fixedly installed on the outer side of the pressing block 501, and the connection method between the pressing block 501 and the cushion block 404 is active abutment.

[0030] In this embodiment: when it is necessary to add lubricating oil to the mold body 1, the personnel moves the pressing block 501 backward through the dial button 504, so that the magnetic block 503 at the rear end of the pressing block 501 adsorbs the rear end of the guide rail 502. After adding lubricating oil to the mold body 1, the personnel moves the pressing block 501 forward through the dial button 504, so that the magnetic block 503 at the front end of the pressing block 501 adsorbs the front end of the guide rail 502. At this time, when the punch head 2 moves down to punch the washer, the injection structure 4 will not contact the pressing component 5, thereby avoiding the waste of lubricating oil.

[0031] Embodiment 3

[0032] See also Figure 3This embodiment further illustrates other embodiments, that a plurality of rubber valves 6 equidistantly distributed around a circumference are fixedly embedded inside the oil nozzle 410, and the connection between two connected rubber valves 6 is a movable abutment, and the multiple rubber valves 6 can seal the oil nozzle 410 by movably abutting against each other.

[0033] In this embodiment: when the piston 402 moves downward to squeeze the lubricating oil inside the sleeve 401 into the annular tube 409, since the inside of the annular tube 409 is full of oil, when the piston 402 moves downward, the multiple rubber valves 6 in the multiple oil nozzles 410 will open under the action of liquid pressure, and the lubricating oil will enter the interior of the mold body 1 through the oil nozzles 410, which is conducive to making the lubricating oil evenly distributed in the mold body 1. After the piston 402 moves upward, the rubber valve 6 will recover under its own elastic performance to seal the oil nozzle 410.
