It features high strength, high hardness, high wear resistance, sufficient toughness, and good thermal fatigue performance. According to its application, it can be divided into cold work die steel, hot work die steel, and plastic mold steel. Cold work die steel is used to manufacture molds that deform metal in a cold state, hot work die steel is used to manufacture molds subjected to thermal cycling loads, and plastic mold steel is used to manufacture plastic molding dies. Die steel has wide applications in many industries such as machinery manufacturing, automobiles, and electronics. It is a key material to ensure mold quality and lifespan, and to improve production efficiency and product quality.

[0003] Currently, when processing mold steel, it is necessary to quickly and stably introduce nitrogen into the equipment. This requires the use of nitrogen cylinders to input nitrogen into the equipment. At present, when connecting nitrogen to the equipment, bolts are usually used for a relatively stable connection. By rotating the nut or connector, the two are quickly tightened together. However, the connection and disassembly speed is relatively slow, which affects the connection speed between the nitrogen cylinder and the processing equipment. Utility Model Content

A mounting plate 7 is welded to the upper surface of the first connector 3. A mounting groove 8 is provided on the lower surface of the mounting plate 7. The gear 5 is rotatably mounted inside the mounting groove 8. The gear ring 6 is fixedly mounted on the outer surface of the connecting nut 4. The gear 5 and the gear ring 6 are meshed and connected. A first circular groove 9 is provided on both the left and right inner walls of the mounting groove 8. A rotating rod 10 is rotatably mounted inside the first circular groove 9. The rotating rod 10 is fixedly connected to the gear 5.

[0025] Furthermore, the auxiliary docking mechanism also includes a rotating plate 11. A second circular groove 12 is provided on the left surface of the mounting plate 7. The second circular groove 12 communicates with the interior of the first circular groove 9 on the left side. The rotating plate 11 is rotatably installed inside the second circular groove 12. The rotating plate 11 is fixedly connected to the rotating rod 10. A hexagonal groove 13 is provided on the left surface of the rotating plate 11.

[0026] Furthermore, by using an electric wrench to rotate the rotating plate 11, the rotational force is transmitted to the connecting nut 4 through the meshing transmission of gear 5 and gear ring 6, enabling rapid tightening and loosening. Compared with the traditional manual direct tightening of the connecting nut, the operation is easier, shortening the docking and disassembly time between the nitrogen cylinder and the processing equipment, thereby improving the processing efficiency of mold steel.

[0027] Furthermore, a second connector 14 is threaded onto the left end of the inner wall of the connecting nut 4.
