Glass aspheric-surface optical lens die-casting die structure

The utility model relates to a glass aspheric-surface optical lens die-casting die structure which comprises a lower die core, an upper die core and a die sleeve. A die sleeve hole is formed in the die sleeve. The lower die core and the upper die core are arranged in the die sleeve hole. A conic surface matching locating structure is arranged on the matched end face of the lower die core and the upper die core. According to the die structure, glass aspheric-surface eccentric accuracy can be improved and it can be guaranteed that eccentric stability in production is good.
