Disclosure of Invention
The utility model aims at: in order to overcome the defects of the prior art, the utility model provides a die holder for lens cutting, it can fix a position lens group well, and the position can not squint when guaranteeing the cutting.
The technical scheme of the utility model: a die holder for lens cutting, characterized in that: the lens positioning device comprises a base body, wherein a regular polygonal containing cavity is formed in the base body, each side wall of the containing cavity forms a rear pressing edge used for pressing the rear side wall of a lens, bosses are respectively arranged in the containing cavity corresponding to the positions of each side wall of the containing cavity, a front pressing edge used for pressing the front side wall of the lens is arranged on each boss, a lens positioning groove is formed between each front pressing edge and the corresponding rear pressing edge, and at least one pair of positioning blocks used for abutting against the left side wall and the right side wall of the lens is arranged in each lens positioning groove.
By adopting the technical scheme, the number of the sides of the accommodating cavity is matched with the number of the lenses, and if ten lenses are formed by injection molding of an injection molding machine at the same time, the accommodating cavity is in a regular decagon shape; when the lens group is placed in the accommodating cavity, each lens is placed in each lens positioning groove, the front pressing edge and the rear pressing edge are respectively pressed on the front side wall and the rear side wall of the lens in a pressing mode, the positioning blocks are used for abutting against the left side edge and the right side edge of the lens to well position the lens, and the position cannot deviate during cutting.
The utility model discloses a further setting: each locating piece sets up in two adjacent lens constant head tank intercommunication positions, and the both sides of locating piece all are equipped with the arc locating surface.
By adopting the further arrangement, the same positioning block can be used for respectively positioning the lenses in the two adjacent lens positioning grooves, so that the number of the positioning blocks can be saved, the whole structure is simple and compact, and materials are saved; the arc locating surface can be matched with the left side wall and the right side wall of the lens, and the locating effect is better.
The utility model discloses a further setting again: the boss is correspondingly arranged at the intersection position of two adjacent side walls of the accommodating cavity, and two front pressing edges for respectively pressing the front side walls of two adjacent lenses are arranged on the boss.
Adopt above-mentioned further setting again, two preceding pressing edges of same boss can be contradicted the location to the preceding lateral wall of the lens in two adjacent lens constant head tanks simultaneously, can make the location of lens more stable like this.
The utility model discloses a still further set up: the bottom of lens constant head tank is equipped with the recess, and the locating piece setting is in the bottom of recess.
By adopting the further arrangement, the groove can greatly save materials, reduce the weight of the die holder and save the cost; moreover, the lens can be clamped conveniently after the lens is cut, and the lens can be clamped in a certain space of the clamping jaw.
