Problems solved by technology

[0008] Although the forming method uses the above-mentioned device to directly shape the molten glass into a glass lens, however, when this forming device transfers the glass preform 9, the The glass preform 9 will also drop quickly onto the lower mold core 801 due to gravity, therefore, the glass preform 9 will also be damaged due to impacting the lower mold core 801

Abstract

The invention relates to a molding device of optical glass pre-form that can be connected with a pressure source, thereby forming the optical glass pre-form. The molding device comprises a die holder. The die holder is provided with a temporary hole surface surrounding an axis and a temporary hole determined by the temporary hole surface. The invention also comprises gas supply space surrounding the axis and communicated with the temporary hole and the pressure source. The gas supply space is provided with a gas outlet part surrounding the axis and formed over the temporary hole surface; the gas outlet part can output the gas of the pressure source from the side of the temporary hole surface to the temporary hole, thus the glass pre-form can float over the gas outlet part.

Description

technical field [0001] The invention relates to a forming device, in particular to an optical glass preform forming device capable of preventing the impact damage of the glass preform during the forming process. Background technique [0002] like figure 1 As shown, there is an existing floating forming device for forming a glass preform 2, which includes a forming seat 1, which can be connected with an air pressure source (not shown) for supplying gas, and the forming seat 1 It has a forming surface 101 , a forming hole 102 with a V-shaped cross section, and an air inlet 103 communicating with the forming hole 102 and the air pressure source and having a diameter smaller than the outer diameter of the glass preform 2 . Thereby, when a platinum outflow tube (not shown) drops a molten glass (not shown) into the forming hole 102, the gas supplied by the air pressure source can be transported from the air inlet 103 to the forming hole 102. The hole 102 is formed so that the mo...
