发明名称 DEVICE FOR FORMING GLASS OPTICAL ELEMENT
摘要 PROBLEM TO BE SOLVED: To provide a device for molding a glass optical element, in which a glass optical element stuck to a mold can be peeled off and taken out with ease and reliability. SOLUTION: In the device for forming a glass optical element, a glass blank is pressed by an upper convex molding surface 1a of an upper mold 1 and a lower concave molding surface 2a of a lower mold 2, to form a glass optical element, that is, a glass lens 19. Immediately after forming, the upper optical surface of the glass lens 19 is stuck to the convex surface. A slight space is formed between the convex surface 1a of the upper mold 1 and the glass lens 19 being present in the holding ring 18 by sliding an upper axis 3 and an upper molder 1 in an inclined direction toward P1 against a lower molder 2 through a supporting portion of the upper molder arranged on a upper side of an upper axis 3, in order to release the glass lens 19 from sticking. The lens is released with reliability by the above procedure. COPYRIGHT: (C)2007,JPO&INPIT
