The vibration rod 23 is arranged, the vibration rod 23 enables the first magnetic attraction piece 13 to synchronously act with the third magnetic attraction piece 24 when in motion by arranging the third magnetic attraction piece 24, the third magnetic attraction piece 24 is subjected to magnetic attraction force to move outwards, the tail end of the vibration rod 23 is pulled, the vibration rod 23 is bent under the action of magnetic force due to the fact that the tail end of the vibration rod 23 is bent, when the third magnetic attraction piece 24 is not subjected to the action of magnetic attraction, the vibration rod 23 is reset suddenly under the elastic force of the vibration rod 23, the whole vibration rod 23 can vibrate under the action of inertia, larger liquid drops in steam entering from the outer port of the movable barrel 8 are contacted with the surface of the vibration rod 23, and the liquid drops are further scattered by the vibration rod 23 subjected to the vibration of the high frequency vibration, so that the large liquid drops are scattered into small liquid drops.

By providing the vibrating wire 25, the contact probability of the liquid in the steam with the surface of the vibrating rod 23 can be further improved, so that the vibrating rod 23 can better capture large liquid drops in the steam entering from the outer end of the movable barrel 8.
The overall workflow of the invention is as follows:
installing the welding mould 1 at a position between two cable conductor joints; putting a copper sheet into a combustion chamber 2 in a welding mould 1, pouring combustion medicine into the copper sheet, igniting the combustion medicine, and covering a steam generating device on the top end of the welding mould 1; the high temperature generated during the combustion of the combustion medicine melts the copper sheet to generate high temperature metal liquid, the high temperature metal liquid flows into the forming cavity 4 through the communicating cavity 3, in the process, part of the heat generated by the combustion of the combustion medicine is absorbed by the steam generating device, and a large amount of steam is stored in the heat exchanging barrel 20 due to the absorption of heat by water in the water storage cavity in the heat exchanging barrel 20 of the steam generating device;
when the generated high-temperature metal liquid fully enters the forming cavity 4 but is not completely solidified and formed, an operator opens a steam discharge pipe 22 control valve of the steam generating device, high-temperature steam in the steam generating device enters a gas transmission pipeline 17, and part of the steam enters the gas storage cavity 6 through the gas transmission pipeline 17, the auxiliary pipe 16 and the gas injection pipe 15, so that the pressure in the gas storage cavity 6 is increased; part of steam is directly discharged through a gas transmission pipeline 17 to drive an impeller 18 to rotate, so that the impeller 18 drives a rotating shaft 12 to rotate, the rotating shaft 12 drives a first magnetic attraction piece 13 to do circular motion, the first magnetic attraction piece 13 intermittently generates magnetic attraction on a second magnetic attraction piece 14 in a gas storage cavity 6, a movable cylinder 8 continuously stretches and contracts in an exhaust pipe 7 under the action of magnetic force received by the second magnetic attraction piece 14, and when a second ventilation hole 10 on the movable cylinder 8 is aligned with a first ventilation hole 9 on the exhaust pipe 7, high-pressure steam in the gas storage cavity 6 can be discharged into incompletely solidified metal liquid in a communication cavity 3, bubbles are generated in the metal liquid, the bubbles can be blocked by the metal liquid in the floating process, and in the process of gradually solidifying the metal liquid, the bubbles remained in the metal liquid can enable a large number of air holes to be generated in solidified metal;
after the welding mould 1 is taken off like this, because of the existence of a large amount of air holes in the convex metal column above the cable joint, the structural strength is low, the welding mould can be knocked down very easily, operators only need to cut off the convex metal column below the cable joint by using a tool, and the welding workload of the joint is greatly reduced. The bottom cavity 5 below the forming cavity 4 is not provided with an air hole generating device in order to avoid a great amount of air holes generated by the metal in the forming cavity 4 in the air bubble floating process.
