The magnetic adsorption pressing assembly 30 and the magnetic adsorption lifting assembly 40 are arranged oppositely. There are two groups of magnetic adsorption pressing assemblies 30, and the two groups of magnetic adsorption pressing assemblies 30 are symmetrically distributed with reference to the midline of the upper die assembly 60.

When taking out the felt, the lifting cylinder 41 drives the lifting buckle plate 43 to descend, so that the lifting buckle plate 43 is clamped into the lifting buckle seat 63. At the same time, the lifting electromagnet 42 is started, so that the lifting electromagnet 42 adsorbs the upper die assembly 60, and then the upper die assembly � is driven by the lifting cylinder 41 to rise, separating the upper template 65 from the lower die holder 50, taking out the felt.

After the pressing is completed, the pressing of the felt can be continuously carried out.

[0067] Refer to Figures 1-4 , during the pressing operation, the pressing slide table assembly 10 drives the lower die base 50 to move below the magnetic adsorption pressing assembly 30, and then by combining the pressing buckle plate 33 on the pressing electromagnet 32 with the pressing buckle seat 62, the pressing hydraulic cylinder 31 drives the upper template 65 on the upper die carrier 61 to descend, so that the upper template 65 is combined with the lower die base 50 to press the felt. After the pressing is completed, the pressing electromagnet 32 is powered off, so that the magnetic adsorption pressing assembly 30 is separated from the upper die assembly 60, completing the combination of the lower die base 50 and the upper die assembly 60. At the same time, when the lower die base 50 and the upper die assembly 60 are combined, the plugging column 72 is inserted into the plugging socket 74, so that the template fixing assembly 70 fixes the lower die base 50 and the upper die assembly 60, enabling the upper die assembly 60 and the lower die base 50 to be combined together. After the pressing is completed, the pressing of the felt can be continuously carried out. When taking out the felt, the pressing slide table assembly 10 drives the lower die base 50 to move below the magnetic adsorption lifting assembly 40, and the lifting cylinder 41 drives the lifting buckle plate 43 to descend, so that the lifting buckle plate 43 is clamped into the lifting buckle seat 63. At the same time, the lifting electromagnet 42 is started, so that the lifting electromagnet 42 adsorbs the upper die assembly 60, and then the lifting cylinder 41 drives the upper die assembly 60 to rise, separating the upper template 65 from the lower die base 50 to take out the felt. Finally, the magnetic adsorption lifting assembly 40 clamps the upper die assembly 60 into the lower die base 50 for next use.
