[0013] The mold steel production is used to the large batch nitrogen cylinder cooling device, through the need to use nitrogen cylinder from top to bottom into the annular box and support ring, so as to drive the circular plate to move down, so as to drive the corresponding lifting rod to move down, so as to drive the corresponding lifting plate to move down, so as to drive the baffle to move down to expose the corresponding water pipe, so that when all the nitrogen cylinder is installed, the water pump can be started to inject the water in the water tank into the square box, and the water injected into the square box will enter the corresponding water outlet through the exposed water pipe, and then the water will enter the annular box, so that the water can be sprayed to the surface of the nitrogen cylinder through the nozzle on the annular box, so as to cool the nitrogen cylinder, and the position without nitrogen cylinder will not be sprayed out due to the blocking of the baffle, so as to avoid the evaporation speed of the water spray too fast, so as to reduce the consumption of water resources, and the water flowing down along the nitrogen cylinder will enter the square pipe through the water bucket, and then the water will flow back to the water tank through the small pipe.

[0014] The mold steel production is used to the large batch nitrogen cylinder cooling device, through the sealing ring can avoid the water in the square box through the lifting pipe and the bottom pipe into the lifting pipe and the bottom pipe, and the lifting pipe is blocked by the lifting plate, and the bottom pipe is fixedly connected with the long pipe, so as to avoid the water entering the lifting pipe and the bottom pipe, so as to avoid the contact between the pressure spring and the water, so as to avoid the decrease of service life, and the through slot can keep the flow of air inside the lifting pipe when the lifting pipe moves up and down, so as to keep the smoothness of the lifting pipe moving up and down.

[0015] The mold steel production is used to the large batch nitrogen cylinder cooling device, through placing all the nitrogen cylinders needed, the top plate can be pressed down, so as to drive the nitrogen cylinder to move down, and then the top plate is fixed, so as to fix the nitrogen cylinder by the pressure of the pressure spring upward pressing the top plate.
