[0002] Sound-absorbing cotton is an artificial inorganic fiber. Using natural ores such as quartz sand, limestone, and dolomite as the main raw materials, and mixing some chemical raw materials such as soda ash and borax to melt into glass. In the molten state, it is blown or spun into flocculent fine fibers by external force. The fibers are three-dimensional and cross each other, winding together, presenting many small gaps.

[0003] According to a sound-absorbing cotton pressing die provided by the patent application number CN202222539306.7, compared with the prior art, this device can prevent the cut and hot-pressed sound-absorbing cotton from adhering to the cutter ring frame or the hot-pressing ring frame, so that there is no need for staff to separate the two subsequently, which ensures the safety of this device to a certain extent.

[0004] The disadvantages of the above device are as follows: during the use of the device, the material positioning of the entire device is not precise.
