INJECTION MOLD FOR MANUFACTURING LENS

摘要

PROBLEM TO BE SOLVED: To provide an injection mold for manufacturing a lens, which can displaceably arrange a moving core in a movable mold so that an eccentric phenomenon of the movable core may be prevented with respect to a fixed core when molding the lens.SOLUTION: An injection mold 1 for manufacturing a lens is constituted of: a fixed core 100 having a lens transfer face 101 and one or more pin holes 102; a fixed mold plate 10 having a core attachment part 110 for containing the fixed core 100; a movable core 200 having a lens transfer face 201, one or more guide pins 202 arranged at positions corresponding to the pin holes 102, and one or more bolt holes 240; a movable mold plate 20 having a core attachment part 210 capable of displaceably containing the movable core 200 in a horizontal direction, and bolt-fastened to the movable core 200 by inserting the bolts 220 into the bolt holes 240 penetrating the movable core 200; and one or more elastic members 500 arranged between the movable core 200 and the core attachment part 210.
