Field of the Invention This invention relates to a device and method for fabricating a molded glass lens, and more particularly to a device and method for fabricating a molded aspherical glass lens suitable for use in a digital camera lens. [Prior Art]
[〇〇〇2] 目前，數位相機及帶數位相機之行動電話越來越普及， 對相機之圖像效果及外形輕薄、短小之要求越來越高， 因此對模造非球面玻璃鏡片之需求越來越大，然而，習 知製造模造玻璃鏡片之模具僅包括上模仁及下模仁，因 而一次只能成型一片模造玻璃鏡片。[〇〇〇2] At present, digital cameras and mobile phones with digital cameras are becoming more and more popular. The requirements for the image effect and thinness and shortness of the camera are getting higher and higher, so the demand for molded aspherical glass lenses is increasing. The larger the volume, however, the mold for manufacturing the molded glass lens only includes the upper mold core and the lower mold core, so that only one molded glass lens can be formed at a time.

Referring to the second figure, the molded glass lens device comprises a mold 1, a sleeve 2, a heating device 9 and a fixing ring 4. The mold 1 comprises an upper mold 11, an intermediate mold 13 and a lower mold 15. . The intermediate mold core 13 is located between the upper mold 11 and the lower mold 15, and has a cavity between the upper mold 11 and the lower mold 15, and the fixing ring 4 is located above the intermediate mold 13 for fixing the intermediate mold core. 13 , the sleeve 2 is sleeved outside the mold 1 , and the heating device 9 is sleeved outside the sleeve 2 for heating the glass preform 3 . 1013066313-0 Page 4 / Total 11 pages 1363043 101. February 21st Press the replacement page [0012] The upper die includes an upper base 111, an upper support 113 and an upper mold 115 _ 'the three parts The fixed connection is integral. The upper base 1Π, the upper support U3 and the upper mold core 115 are all cylindrical, and the cross-sectional diameter is larger than the base ill maximum 'upper mold 11 5 minimum' and the upper support 11 3 is located on the upper base 111 and the upper mold core 115 A first curved surface 116 is disposed on the bottom surface of the upper mold core 115 away from the upper support 113. The shape of the first curved surface 116 corresponds to the shape of the molded glass lens required. [0013] The intermediate mold body 13 is a cylinder, and a second curved surface 131 and a third curved surface 133 are respectively disposed on the two bottom surfaces, and the shape thereof corresponds to the shape of the molded glass lens required. [0014] The lower mold 15 includes a lower support 151 and a lower mold core 153, and a fourth curved surface 155 is disposed on a bottom surface of the lower mold core 153 away from the lower support 151. The lower support 151 and the lower mold core 153 are both cylindrical, and the cross-sectional diameter of the lower support 151 is larger than that of the lower mold core 153, and the shape of the fourth curved surface 155 corresponds to the shape of the molded glass lens. [0015] The sleeve 2 is cylindrically shaped to include a first hole 21 and a second hole 26 which are mutually penetrated, and the diameter of the first hole 21 is larger than the diameter of the second hole 26, thereby forming a Step 2 7 to accommodate the intermediate mold 1 3 . [0016] The retaining ring 4 is a cylinder placed in the sleeve 2, and has an outer diameter corresponding to the diameter of the first hole 21 of the sleeve 2 for fixing the intermediate mold core 3. [0017] The upper support 113 and the upper mold 115 are located in the first hole 21, and the outer cylindrical surface of the upper support 113 is matched with the inner cylindrical surface of the first hole 21, and the upper mold is first. The hole 21 moves in the axial direction between a first position and a second position; the intermediate mold 13 is placed on the step 27; the fixing ring 4 is placed in the intermediate mold 09312757#单号Α〇101 Page 5 / A total of 11 pages 1013066313-0 1363043 101. On February 21, the front of the page 13 is replaced by a positive intermediate mold 13; the lower mold 15 of the lower mold 15 is engaged with the second hole 26, and the lower mold 15 is available in the second hole. 26 moves in the axial direction between a first position and a second position. [0018] When manufacturing the molded glass lens, first, the upper mold 11 and the lower mold 15 are each in their first positions, and the two glass preforms 3 are placed on the intermediate mold core 13 and the lower mold 15, respectively, and then the upper mold 11 is placed. And the lower die 15 is biased to move toward the second position, whereby a cavity (not labeled) is formed between the intermediate die 13 and the upper die 11 and the lower die 15, and the two glass preforms 3 are located In the cavity, the heating device 9 works at the same time, heat is transferred to the glass preform 3, and the temperature thereof is raised. The two glass preforms 3 are formed under the action of high temperature and high pressure, and the two-molded glass lens is simultaneously formed. . [0019] It can be understood that the fixing ring 4 of the molded glass lens manufacturing device of the present invention can be omitted, and the intermediate mold core 13 can be fixed by other means, such as by screws or welding, or in the middle of the upper mold core 115. A plurality of mold cavities are respectively formed on the mold core 113 and the lower mold core 153, so that the number of the molded glass lenses in one molding is not limited to two; the upper base 111, the upper support 113, the upper mold core 115, and the intermediate mold core 13. The lower hole 151, the lower mold core 153, the fixing ring 4, and the first hole 21 and the second hole 26 of the sleeve 2 are not limited to a circular shape, and may have other shapes such as a square shape or the like.
