Field of the Invention The present invention relates to a forming apparatus, and more particularly to an optical glass preform forming apparatus which can prevent a glass preform from colliding damage during a forming process. [Prior Art] As shown in Fig. 1, there is a conventional juice forming apparatus for forming a glass preform 2, which comprises a forming seat which is a gas pressure source compatible with a supply gas (Fig. Not shown), the forming seat has a forming surface 101, a forming hole 102 having a V-shaped cross section, and a communicating hole with the forming hole 1 〇 2 and the air pressure source and having a smaller diameter than the outer diameter of the glass preform 2 Air intake hole 103. Thereby, when a platinum outflow pipe (not shown) drops a molten glass (not shown) into the forming hole 102, the gas supplied from the air pressure source can be sent to the forming air through the air inlet hole 103. The hole 1 〇2 floats the molten glass above the forming surface 101, and further rotates the molten glass into a spherical glass preform 2. Although the '5 hai forming I can be used to form the glass preform 2 by ejecting gas through the air inlet 1 〇 3, in actual use, the forming apparatus has the following defects: When the glass preform 2 is taken and placed, the forming device needs to close the air pressure source. Thus, since the sprayed gas no longer supports the glass preform 2, the glass preform 2 will be affected by gravity. And quickly falling onto the forming surface 101. At this time, since the glass preform 2 is still in a high temperature state and the hardness is insufficient, the glass preform 2 tends to be damaged by the impact 5 1302524, and thus becomes no. Good product, which affects production yield. As shown in Fig. 2, there is a floating upper forming device for forming a glass preform 4, which comprises a forming seat 3 which is a pneumatic source for supplying a gas to the disk (not shown). The forming seat 3 has a forming surface 301, a forming hole 3〇2 of a cross-section iu-shape, and a plurality of air inlets communicating with the forming source 302 and the red g source and having a smaller diameter than the outer diameter of the glass preform 4. When the hole-by-field-white gold outflow pipe (not shown) drops a molten glass (not shown) into the 5-shaped forming hole 3〇2, the gas supplied by the air source can also be supplied from the air. The hole 3G3 is conveyed to the forming hole, and the smelting glass is floated over the forming surface 301, and the smelting glass is rotationally formed into the glass preform 4. However, when such a forming apparatus picks up and discharges the glass preform 4, the ink source is also required to be closed. Therefore, the glass preform It 4 also suffers from damage due to impact on the forming surface 301. In addition, it has saved a number of lens pre-treatment processes such as glass preform polishing and cleaning. A method for directly forming a glazed glass into a glass lens has also been proposed (U.S. Patent No. 5,762,673), as shown in Fig. 3. *This method is to use a robot arm 6 to drive a receiving mold 7 to rotate in four processing positions of the forming chamber 5, the robot arm 6 having a left arm 2 6 〇 1 ' and a right arm portion 602 The left and right arm portions 〇1, 602 are mutually slidable or separable in a horizontal direction, and the receiving mold 7 has a left core body 7〇1' mounted on the left #601. The right phantom 702' of the right arm and the shaped vent 703 defined by the left and right phantoms 7〇1, 7〇2. Thus, when the robot arm 6 drives the receiving mold 7 to rotate 6 1302524 to a first processing position (glass preform forming region), a platinum exiting official (not shown) can be used to melt a glass (not shown). Draws into the forming air hole 703, and the molten glass is floated into the glass preform in the forming air hole 7〇3 to form a glass preform 9, after which the robot arm 6 can drive the receiving mold 7 and the glass preform 9 is rotated to a second processing position, and then rotated to a third processing position (forming region), in the third processing position, the left and right arms 601, 6 〇 2 will The left and right mold bodies 7〇1, 702 are separated from each other in the horizontal direction, so that the glass preform 9 is quickly dropped by gravity to the lower mold core 8〇1 of a forming mold 8. An upper mold 802 of the forming mold 8 can be moved downward, and the glass preform 9 is press-formed into a glass lens 9〇1. Although the forming method can directly form the molten glass into a glass lens by the above apparatus, the forming apparatus is transferred to the glass preform 9 and the glass preform 9 is also fast due to gravity. It is dropped onto the lower coix seed 801. Therefore, the glass preform 9 also has a problem of being damaged by the impact of the lower mold core 801. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an optical glass preform forming apparatus capable of preventing impact damage of a glass preform during forming, and an optical glass preform forming apparatus of the present invention An air pressure source is coupled to form a glass preform, the forming apparatus comprising a mold base having a working hole surface surrounding an axial direction, a working hole defined by the working hole surface, and An air supply space surrounding the axial direction and communicating with the working hole and the pressure source of the gas 7 1302524, the air supply space has an air outlet portion surrounding the vehicle direction and formed on the surface of the working hole, the air outlet portion is An annular opening surrounding the axial direction, the working hole surface is bounded by the gas outlet portion, and defines an upper hole surface portion above the f rolling portion and a lower hole surface portion opposite to the upper hole surface portion, 2 The working hole is bounded by the gas outlet portion, and defines an upper hole segment defined by the upper hole surface portion and a lower hole segment defined by the lower hole surface portion, and the The side of the working hole surface is the gas of the air pressure source The job is output to the hole, so that the glass preform is floated on the upper portion of the air outlet.

The first bottom surface U2 has a first horizontal surface portion m' extending inwardly from the first outer circumferential surface 113 and a first inclined surface portion extending inwardly from the first horizontal surface portion 114 to the working hole surface 13 115. The second top surface (2) has a second horizontal surface portion 125' parallel to the first horizontal surface portion 114 and a second inclined surface portion (3) substantially parallel to the first inclined surface portion u5. The surrounding surface 122 There are a plurality of air supply holes 127 connected between the air supply air (five) 15 and the air supply pipes 100. The working hole surface U can define an upper hole surface portion 131 connected between the first top surface and the bottom surface 1U and 112 and extending outward from the bottom, and a second top surface and a bottom surface 123 and 124 connected to the second top surface and the bottom surface 123 and 124. Between the lower hole surface portion 132, the working hole U defines an upper hole portion (4)' defined by the upper hole surface portion 131 and a lower hole portion 142 defined by the lower hole surface portion 132. The bore has a jet opening 143 formed in the first bottom from 112, the lower bore 142 having a transfer opening 144 formed in the second top surface 123, which in the present embodiment has a jet opening (4) A jet aperture m greater than the outer diameter D of the glass preform', the transfer opening (4) having a transfer aperture substantially equal to the jet aperture D1. The air supply space 15 is a boundary between the bottom surface 112 and the second top surface 123. The air supply space 15 has a horizontal section 151 defined between the first and second horizontal planes 9 1302524. The inclination _ 2 between the two and the second and second sides of the working hole surface 13 is around the axial direction x and the gas-shaped portion 153 is - ring: ° 153 'in this In the embodiment, the clothing, the θ χ χ χ χ 介于 介于 介于 介于 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当 当The gap height t is adjusted from: the axial direction X, and when the air outlet is: the surface: the object: the body ... the inclined section 152 is output to the working hole 14 and the glass preform 220 floats on the air outlet Above section 153.吏〜玻璃可二Π 2〇 is sleeved with the lower hole section 142 of the working hole 14, and the disk 2 is V: away from the first position of the air outlet 153 (see Fig. 4): the second position of the air portion 153 Moving between (see Fig. 9), the carrying surface hi has a bearing surface 21 facing the air outlet portion 153, an outer peripheral surface 22 extending downward along the bearing ==, and a substantially equal to the air jet aperture D1 The outer circumferential diameter D3. This as shown in FIG. W, when the platinum outflow pipe _ the molten enthalpy is dripped in the upper hole section 141 of the working hole, the gas supplied by the gas pressure source (10) can be along The U, b inclined section 152 of the air supply space 15 is outputted from the air outlet portion 153 to the upper hole, the cymbal, and the upper portion, and is sprayed upward, so that the dropped molten glass 210 can be floated at the outlet. Above the portion 153, the glass preform is further formed into a spherical shape. Then, as shown in Figs. 7, 8, and 9, when the glass preform 220 is less moved from the glass, the temperature is lowered to the glass.

In the lower hole section 142, and moving from the first position (see FIG. 7) to the second position (see FIG. 9), in the process, since the outer peripheral surface 22 can gradually block the air outlet portion 153, The amount of gas ejected from the gas outlet portion 153 is gradually reduced. Therefore, the glass preform 220 can be gradually lowered onto the bearing surface 21 as the amount of gas ejected decreases, and thereafter, as shown in the figure. As shown in FIG. 1 , the manufacturer can release the carrier 2 〇 from the die holder 1 after closing the air pressure source, and carry the glass preform 220 by the carrier 2 , for subsequent operations. Through the above description, the advantages of the present invention can be further summarized as follows: In the process of receiving the glass preform 220 by the carrier 20, the outer peripheral surface 22 of the carrier 20 can gradually gradually extract the outlet portion. The 153 block is closed, and the amount of gas ejected from the gas outlet 153 is gradually reduced. Therefore, the present invention allows the glass preform 22 to gradually decrease in the amount of gas ejected. On the bearing surface 21, the present invention can effectively prevent the glass The glass preform 220 is damaged by the impact, so that the production yield of the glass preform 220 can be effectively increased. As shown in FIG. 11, a second preferred embodiment of the present invention, the second rut ^ The embodiment of the present invention is similar to the first preferred embodiment in that the cross section of the upper hole section 141 of the working hole 14 is substantially U-shaped, and the glass preform 23 of different shapes can be formed.
