[0026] Specifically, the punching column 5 can punch out a circular hole on the surface of the conical lower hopper, which is used for positioning the punching step 3 and the punching and shearing step 4 during operation. The punching and shearing step 4 is used to punch out an observation window on the outer surface of the conical lower hopper, and the punching step 3 is used to stamp out the glass lens mounting groove at the observation window.

[0027] The outer mold includes a second mounting plate 11, an outer side surface of the second mounting plate 11 is provided with an outer positioning plate 9, a stamping groove 10 is provided on the outer positioning plate 9, a shearing groove 7 is provided inside the stamping groove 10, and two positioning through holes 8 are provided inside the shearing groove 7.
