[0025] The specific implementation process of this utility model is as follows: In use, the output end of the hydraulic cylinder 5 drives the heating plate 6 and the upper mold to move down, so that the upper mold and the lower mold 2 are closed.

[0026] When filtering dust and impurities through the filter plate 13, the rotating motor 91 works simultaneously, driving the rotating shaft 92 and the top block 93 to rotate. The rotation of the top block 93 will squeeze the protrusion 94, which will cause the filter plate 13 to move downward. The filter plate 13 slides along the fixed rod 95, stretching the first spring 97. At the same time, the filter plate 13 will press down the second spring 98. When the top block 93 rotates and separates from the protrusion 94, the elasticity of the spring will give the filter plate 13 a reaction force, realizing the vertical vibration of the filter plate 13, which can shake off the blockage impurities to avoid affecting the air passage.
