Description of the Invention: The present invention relates to a forming apparatus, and more particularly to an optical glass lens forming apparatus which can directly form a molten glass into a glass lens. [Prior Art] In the past, when forming a glass lens, the molten glass was first formed into a glass preform, and the glass preform was generally produced in two ways. One of them was to cut the cooled molten glass into a block shape. Then, the embryo is or pressed into a glass preform or glass ball of a desired shape, and the other is to directly form the molten glass into a glass preform of a desired shape, after which the glass preform is washed and The glass preform can be formed into a glass lens by heating and pressurizing. In order to eliminate the multi-lens pre-molding process of glass preform polishing, washing, etc., a method for directly forming molten glass into a glass lens has been proposed (U.S. Patent No. 5,762,673), as shown in Figs. In this way, the S-manipulator arm 2 drives the receiving mold 3 to rotate in the four processing positions of the forming chamber i. The robot arm 2 has a left arm portion 201, and a right #4 202 '5 left and right arm. The parts 2〇i, 2〇2 are mutually merging or separating in a horizontal direction. The receiving mold 3 has a left core body 3 0 1 , a ^ / ρ» mounted on the left arm part 2〇ι λ loaded. Further, the right mold body 302 of the far right arm portion 202, and the formed air holes 3〇3 defined by the left and right mold bodies 3〇1 and the ground are combined. When 'the machine' 2 rotates the receiving mold 3 to a first filling position (glass preform forming area), - platinum flows out f (not shown, the molten glass (not shown) Dropping into the forming air hole is 5 l3 〇 i 475 ', and the molten glass is placed in the forming air hole 303

The preform 220 is press-formed into the glass lens 230 between the upper and lower molding faces 31, 21, and thereafter, as shown in FIG. 10, when the glass lens 230 is lowered, the dish to the glass transition temperature (Giass) Transition Point, Tg) below, the upper mold core 30 can be slowly removed from the upper hole segment i41, so that the manufacturer can use the suction nozzle to pick up and move the glass lens 23〇, or after closing the air pressure source, use The lower mold core 20 carries the glass lens 23 搬运 for subsequent work flow. Through the above description, the advantages of the present invention can be further summarized as follows: 1. The present invention can consistently operate the molten glass 21 〇 directly into the glass lens 230. Therefore, the present invention can greatly reduce the glass preform grinding, Washing and other conventional lens molding pre-treatment processes can effectively increase the production efficiency of glass lenses. In the process of using the side mold core 20 to receive the glass preform 220, the outer peripheral surface 22 of the lower mold core 20 can gradually block the gas outlet portion 153, and gradually reduce the discharge from the gas outlet portion 153. The gas ejection amount, therefore, the glass preform 22 can be gradually lowered on the lower molding surface 21 as the gas ejection amount decreases, so that the present invention can effectively prevent The glass preform 220 is damaged by impact, and the production yield of the glass lens 230 can be effectively increased. It is to be noted that, of course, the upper and lower phantoms u, 12 of the mold base 10 can also be integrally formed. The air supply space 15 can also be surrounded by a plurality of air passages that surround the axial direction X and point toward the working hole 14. The air outlet portion 153 11 1301475 can also be constituted by a plurality of openings formed on the working hole surface 13 by the air passages, so that the same purpose and effect as the above-described preferred embodiment can be achieved. I invented the optical glass lens "shape i, not only can work directly to make the molten glass directly into a glass lens, but also prevent the glass preform from colliding damage during the forming process, so it can indeed achieve the purpose of the invention. However, the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the embodiments of the present invention, i.e., simple equivalent changes made in accordance with the scope of the invention and the description of the invention. And modifications are still within the scope of the invention patent.
