[0046] like Figure 2 and Figure 3 as well as Fig. 9 and Fig.10As shown, the cooling device 14 also includes two clamping plates 1406, which are fixedly connected to the two sides of the movable mold core 2, and the two clamping plates 1406 are slidably connected to the inner wall of the mounting plate 1401. By setting the clamping plates 1406, the positioning effect can be achieved when the mounting plate 1401 is connected to the movable mold core 2, and the position of the mounting plate 1401 can be conveniently fixed.

By providing the second spring 1410, the position of the limiting rod 1408 can be limited.

[0047] Working principle: when the collision pin 7 pushes the movable block 8 to move close to the first slider 5, the movable block 8 pushes the airbag 1205 to shrink through the push rod 1203, and the shrinking airbag 1205 pushes the lubricating oil in the oil box 1207 into the oil outlet pipe 1210 through the vent pipe 1206. The lubricating oil in the oil outlet pipe 1210 enters the oil distribution pipe 1212 through the ring pipe 1211, and soaks the second sponge ring 1204. When the movable block 8 drives the connecting ring 1201 and the first sponge ring 1202 to approach the second sponge ring 1204, the first sponge ring 1202 is soaked with the lubricating oil. When the first spring 9 pushes the movable block 8 to move away from the first slider 5, the first sponge ring 1202 coats the inner wall of the needle 6 with the lubricating oil, so that when the movable block 8 moves again, the surface of the movable block 8 can be coated with the lubricating oil, so as to achieve As for the lubricating effect of the movable block 8, when it is necessary to add lubricating oil to the oil box 1207, unscrew the threaded cover 1209, inject the lubricating oil into the oil box 1207 through the oil inlet pipe 1208, and then tighten the threaded cover 1209. By setting the collar 1213, the second sponge ring 1204 can be installed. By setting the lubricating device 12, when the mold with the break protection mechanism is used, when the fine needle head 4 of the fine needle body 3 contacts the collision needle 7, the collision needle 7 can be collected into the sleeve needle 6 and returned to the original position through the movable block 8 and the first spring 9, and the lubrication of the movable block 8 can be completed at the same time, thereby ensuring that the movable block 8 can run smoothly during long-term use, thereby avoiding damage during the processing and production of ultra-fine needles as much as possible.

[0048] When it is necessary to use a mold with a break protection mechanism, first move the fixed mold core 1 close to the movable mold core 2, at which time the positioning block 1301 contacts the movable mold core 2, and then rotate the threaded rod 1307 to make it rotate on the inner wall of the fixed plate 1306 and the surface of the first push plate 1305, so that the first push plate 1305 drives the second push plate 1312 to move through the connecting plate 1308. The movement of the first push plate 1305 and the second push plate 1312 respectively drives the second slider 1304 and the third slider 1311 to slide on the surface of the first slide groove on the first "L"-shaped plate 1303 and the second slide groove on the second "L"-shaped plate 1310, and the first push plate 1305 and the second push plate 1312 respectively drive the second slider 1304 and the third slider 1311 to slide on the surface of the first slide groove on the first "L"-shaped plate 1303 and the second slide groove on the second "L"-shaped plate 1310. The movement of the first push plate 1305 and the second push plate 1312 pushes the fixed mold core 1 to move close to the first positioning plate 1302 and the second positioning plate 1309, completing the positioning work of the connection between the fixed mold core 1 and the movable mold core 2, and then the two are fixed by the first fixing rod 10 and the second fixing rod 11. By setting the positioning device 13, the positioning effect can be achieved during the assembly of the fixed mold core 1 and the movable mold core 2, thereby facilitating the adjustment of the position of the fixed mold core 1 after moving the fixed mold core 1 close to the movable mold core 2 and improving the accuracy of the position adjustment, thereby improving the efficiency of the staff in connecting the fixed mold core 1 and the movable mold core 2.

[0049] When it is necessary to use a mold with a break protection mechanism, first pull the pull plate 1409 to drive the limit rod 1408 to slide on the inner wall of the curved plate 1407, so that the pull plate 1409 moves away from the curved plate 1407, and then move the mounting plate 1401 close to the movable mold core 2, so that the clamping plate 1406 is clamped into the inner wall of the mounting plate 1401, release the pull plate 1409, and under the action of the elastic force of the second spring 1410, the limit rod 1408 moves close to the clamping plate 1406 to complete the installation of the mounting plate 1401, and then start the water pump 1404, which passes the coolant in the cooling water tank 1402 through the cooling water tank 1402. The coolant is drawn into the cooling pipe 1405 through the outlet pipe 1403, and then enters the cooling water tank 1402 through the cooling pipe 1405 to complete its circulation process. In this process, the cooling pipe 1405 can achieve the heat dissipation effect for the mold with a break protection mechanism. By setting up the cooling device 14, the heat dissipation efficiency of the fixed mold core 1 and the movable mold core 2 can be improved after the production process is completed using the fixed mold core 1 and the movable mold core 2, thereby accelerating the heat dissipation speed of the product as much as possible and improving the production efficiency. At the same time, it can avoid the temperature of the fixed mold core 1 and the movable mold core 2 from affecting the dimensional accuracy of the product as much as possible, and ensure the product quality as much as possible.
