DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of glass forming apparatuses, and more particularly to a precision-formed bi-concave or plano-concave type (plano) -concave) The mold of the lens molding glass. [Prior Art]
按’習知用以成形光學玻璃之模具，其結構大體 上包含相對之一模仁套筒，一下模仁，固定於模仁套 筒内而可供玻璃素材置放，一上模仁，可上下移動地 對應下模仁。操作時，上模仁在高溫模造過程中可下 移而促使玻璃素材受上、下模仁之塑形面壓制進而成 形為玻璃鏡片，當上模仁上移後，再利用工具（如吸嘴） 將玻璃鏡片取出，以進行後續之加工處理。由於玻璃 素材在下模仁之塑形面上並未固定，因此受壓過程中 易發生偏移下模仁中心軸線而成為不良品之情形。盆 次’下模仁之塑形面係呈凸面狀，即使係使用一平二 凹或其他型式之玻璃素材亦無法改善易滑移或偏移之 現象，此即雙凹面型玻璃鏡片製造上遠較一般雙凸或 一凹一凸面型玻璃鏡片困難之原因。According to the conventional mold for forming optical glass, the structure generally comprises a relatively one-piece mold sleeve, and the lower mold core is fixed in the mold core sleeve for the glass material to be placed, and the upper mold core can be Move up and down to correspond to the lower mold core. During operation, the upper mold core can be moved down during the high temperature molding process, and the glass material is pressed by the molding surface of the upper and lower mold cores to form a glass lens. When the upper mold core is moved up, the tool (such as a suction nozzle) is used. The glass lens is removed for subsequent processing. Since the glass material is not fixed on the molding surface of the lower mold core, it is liable to cause the center axis of the lower mold core to become a defective product during the pressing process. The shape of the basin's lower mold is convex, even if it uses a flat or concave glass or other type of glass material, it can not improve the slip or offset. This is the production of double concave glass lens. The reason why the double convex or concave concave convex glass lens is difficult.

Although the disclosure of the patent publication can solve the phenomenon that the glass material is easy to slip or shift, the angle of the conical section of the inner wall of the sleeve of the 931151〇7 patent publication must be very sharp. The effect of positioning the glass material on the central axis of the lower mold core, on the contrary, increases the difficulty in the mold making process, and the addition of the sleeve in the patent publication No. 93132915 also causes the disadvantage of making the mold making difficulty. SUMMARY OF THE INVENTION The main object of the present invention is to provide a mold for solving the previously lost mold glass, which is not only compact in structure, but also easy to mold, and at the same time can position the glass coffin without forming. The phenomenon of slipping time. Therefore, in order to achieve the foregoing object, the present invention provides a mold for molding glass, which can accurately position a circular glass material, and includes a mold group including an upper mold core and a lower mold core; a sleeve group, The upper mold core sleeve and the lower mold core sleeve are respectively sleeved on the outer side of the upper mold core and the lower mold core for forming a chamber between the upper and lower mold core sleeves and the upper and lower mold cores The inner diameter of the chamber is similar to the outer diameter of the circular glass material, and the corresponding end of the upper mold sleeve and the lower mold sleeve is provided with a flashing area corresponding to one of the chambers. 6 1328567 [Embodiment] Hereinafter, two preferred embodiments of the present invention will be described in detail with reference to the drawings. First, referring to the first embodiment, a molded glass according to a preferred embodiment of the present invention is shown. The mold 1 can be used for forming a circular glass material, which is composed of a mold group 12 and a sleeve group 14. The mold core group 12 has a corresponding upper mold core 22 and a lower mold core 24'. The corresponding ends of the upper mold core 22 and the lower mold core 24 are respectively provided with a molding surface 23, 25. The sleeve set 14 has an inner diameter sleeve (9) and a lower mold sleeve 28 having the same inner diameter. The upper mold sleeve 26 is sleeved on the outer side of the upper mold core U. The lower mold core (four) 28 series The sleeve is placed on the lower mold core (4), and the side, and the upper and lower mold sleeves 26 and 28 are formed to form a chamber 30. In addition, the mold core 22, 24 further includes a sleeve positioning member 16, a mold core sleeve 28 top material edge, and (4) a strong sleeve 2 of the lower corresponding sleeve positioning member 16 socket 32, two bottom jaws N 9R nr ^ ^ is provided for the upper mold sleeve 26 to be moved downward and the socket 32 is abutted against the sleeve positioning member "when the sleeve sleeves 26, 28 can be gapped together" 34. The operation method of the 溢 一 溢 溢 溢 · · · · · · · · 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一 一Therefore, it is possible to accurately position without significant tilting or offset, and when the upper mold core sleeve 26 and the upper mold core 22 are moved downward to press the circular glass material 20, the force applied and the glass deformation are uniform. And the portion of the extruded circular glass material 20 enters the flashing zone 34, as shown in the second figure, after the forming is completed, the upper mold core sleeve 26 and the upper mold core 22 are separated and the circular glass is separated. The material 20 is deformed into a lens body 4 〇, and the flange of the lens body 4 可供 can be taken out for clamping, and the lens can be prevented from touching the lens embryo during clamping. The body 4 〇 optical surface and facilitates the mechanical automatic clamping action for subsequent processing into a lens. It can be seen from the above that the mold 1 〇 can not only accurately position the circular glass material without glass offset The disadvantage of producing a defective product is 'and' by the design of the flashing zone, the edge of the formed lens body body can be easily clamped, and the optical surface can be prevented from being touched when the lens body is clamped. In view of the above, the present invention not only can greatly reduce the manufacturing cost of the glass material, but also meets the requirements of the high-precision glass molded lens, and has great commercial value. As shown in the third figure, it is another preferred embodiment of the present invention. The mold 5 of the embodiment has a structure substantially the same as that of the mold 1 , except that the inner diameter of the inner sleeve 52 is larger than the lower mold sleeve 54 , and the sleeve positioning member 56 is fixed and fixed. The top end of the lower mold sleeve 54 is configured to form an overflow region 6G between the inner wall of the upper mold sleeve 52, the upper mold core (four) end and the lower mold core (four) 54. Thereby, the mold 50 is also bean 1328567 Before the release of the effect of the person. The mold for molding glass provided by the invention not only has a simple structure, but also can accurately position the glass material without slipping during forming, and can avoid the occurrence of the optical surface being touched when the mirror body is clamped. In the case of contact, there is a quotient (four) value; the reason is that the invention does meet the requirements of the invention patent, and the application is filed according to law.
