Abstract
A lens mold comprises a first pressing portion, a second pressing portion, and a shaping portion disposed between the two, which comprises an upper slide and a lower slide. The upper slide and the lower slide are connected to the second pressing portion, and can slide along each other. A mold cavity in fluidic communication with a flow path and the inlet such that the lens material flows from the inlet to the mold cavity along the flow path to form a shaped lens. After the lens is formed, the upper slide and the lower slide away from each other separately, where a part of the shaped lens is remains in a recess defined in the second pressing portion, to help release the shaped lens from the mold.
Claims6
A lens mold, comprising:
- a first pressing portion defining an inlet to receive material to make a lens;
- a second pressing portion;
- a shaping portion disposed between the first pressing portion and the second pressing portion, the shaping portion comprising an upper slide and a lower slide connected to the second pressing portion, the upper and lower slides configured for sliding along each other;
- a mold cavity in fluidic communication with a flow path and the inlet such that the lens material flows from the inlet to the mold cavity along the flow path, the mold cavity and the flow path contoured to define at least one surface of the lens, wherein contours of the mold cavity and the flow path are defined when the upper slide and lower slide close;
- and
- a recess defined on a surface of the second pressing portion that is adjacent to the shaping portion, the recess in fluidic communication with the flow path when the upper slide and the lower slide close so as to receive a portion of the lens material.
