[0025] The working principles and beneficial effects of the above embodiments.
[0026] When in use, after the button shell between the first mold 10 and the second mold 11 is cooled and formed, the first driving device 2 drives the connecting plate 7 to move to the left, so that the second mold 11 leaves the first mold 10, until the protrusion 15 hits the push rod 902, so that the push rod 902 is forced to push the moving block 901, and the moving block 901 moves along the guide column 8 and approaches the second mold 11, the spring 909 is deformed, and the push rod 903 moves outward along the inner groove 16, so that the annular push plate 906 pushes the button shell outward, and then the first driving device 2 is used to make the annular push plate 906 return to the corresponding position in the inner groove 16, and the outer ring and inner ring of the annular push plate 906 are respectively provided with an outer layer spacer 907 and an inner layer spacer 908.
