Centrifugal rotary casting machine for manufacturing multi-component glass optical fiber preform

The utility model discloses a centrifugal rotary casting machine for manufacturing a multi-component glass optical fiber preform, and relates to glass optical fiber preform production equipment, in particular to manufacturing of various multi-component glass optical fiber preforms such as fluoride glass rods, silicate glass rods, tellurate glass rods and phosphate glass rods. The forming machine is composed of a rack, a forming mold, a mold overturning mechanism, a mold rotating mechanism, a heat preservation furnace moving mechanism and a heat preservation furnace. The forming mold is arranged to be of a multi-petal structure, demolding of the formed glass rod is facilitated, and station switching of the forming mold is achieved through the mold overturning mechanism; the mold overturning mechanism is located above the rack, and the mold rotating mechanism is used for achieving spinning of a forming mold; a hearth of the heat preservation furnace is hollow and closed on one side, and the center height of the
