Embodiment 1
[0062] Embodiment 1: as Figure 1-12 As shown, in the centrifugal rotary pouring machine, the forming mold 2 has a multi-lobe structure, which is convenient for demoulding the formed glass rod. Forming mold 2 is designed with two stations: vertical station and horizontal station. The forming mold 2 realizes station switching through the mold turning mechanism 3 . The mold turning mechanism 3 is located above the frame 1, and the center of rotation intersects and is perpendicular to the center of the horizontal station of the forming mold 2. The mold rotation mechanism 4 is used to realize the spin of the molding mold 2, so that the components of the glass rod are fully diffused and homogenized during the cooling process of the glass rod. The holding furnace 6 is used to form a certain heating and cooling environment, so that the components of the glass rod can be fully diffused and homogenized, and defects such as cracks caused by internal stress during molding will not be c...

The invention 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 casting 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 heat preservation furnace coincides with the center of the forming die in a horizontal state; the heat preservation furnace moving mechanism is installed below the rack, and station switching of the heat preservation furnace is achieved through a heat preservation furnace moving motor, a ball screw, a guide rail and a moving platform.
Description
technical field [0001] The invention relates to a centrifugal rotary pouring machine for manufacturing multi-component glass optical fiber preforms, which relates to a production equipment for glass optical fiber preforms, especially for fluoride glass rods, silicate glass rods, tellurate glass rods , phosphate glass rods and other multi-component glass optical fiber preforms. Background technique [0002] In recent years, the optical properties of various glass optical fibers have been continuously discovered and recognized, and have shown value in optical devices, communications, and laser transmission. Traditional mold forming is difficult to control the forming temperature gradient, diffusion homogenization, etc., and the formed preform has poor consistency. In view of the wide variety of glass optical fiber materials and the different doping ratios of each component, in order to adapt to the research and industrialization acceleration, a fast, stable and reliable equip...
