Abstract
The utility model provides a demoulding buffering device of resin lens mould maker, which includes a lower suck head cover mounted at the upper of the main axes, the lower sunk plate mounted in the cover is communicated with an air-path; the axes support-seat is provided with blind holes and the helix spring is mounted in the blind holes, the upper end of the helix spring impenetrates the top-out plate and peaks the bottom surface of the upper cover plate. A certain range of relative activity space is provided between the upper cover plate and the top-out plate because of the buffer spring mounted on the axes support-seat; when the upper suck head cover touches the lower suck head cover through the aluminium mould, the rigidity clash-force caused is absorbed by the spring, and the lower mould plate in the lower suck head cover and the lower suck head cover are accordingly drops, which avoids the phenomenon that the mould plate or the aluminium mould are damaged.
Description
Technical field:
The utility model relates to the eyeglass maker, particularly to the improvement of resin lens moulding machine counterdie.
Background technology:
Existing resin lens needs to make earlier the embryo sheet when making, polishing is shaped according to diopter then.When making the embryo sheet, move down by last suction nozzle cover of stepper motor drive and last sucker, when moving to the aluminum dipping form thickness that sets, step motor stop, program controller memory area data, sucker holds matrix up and down respectively up and down, the stepper motor counter-rotating drives to go up on the sucker and moves, and takes out aluminum dipping form; Stepper motor drives sucker once more and is displaced downwardly in advance the memory height then, by adhesive tape strip winding mechanism matrix periphery up and down around on adhesive tape, constitute die cavity up and down between the matrix, in the chamber, inject resin and promptly form the embryo sheet.But descend when touching the top at the pre-for the first time note altitude information of last suction nozzle cover, produce rigid impact power sometimes and damage matrix or aluminum dipping form, need make matrix or aluminum dipping form again, embryo sheet make efficiency is reduced with aluminum dipping form.
Summary of the invention:
The purpose of this utility model provides a kind of buffer gear that can prevent the resin lens moulding machine counterdie that matrix or aluminum dipping form damage.
The utility model comprises the following suction nozzle cover that is installed on the lower main axis, and the following sucker of installing in the cover communicates with air flue, it is characterized in that bearing spider has blind hole, and helical spring is installed in the hole, and liftout plate and upper cover plate bottom surface Xiang Ding are run through in the helical spring upper end.Four helical springs that are installed in the bearing spider are the diagonal distribution.
The utility model is owing to installed buffer spring in bearing spider, and this spring is in free state at ordinary times, be upper cover plate with liftout plate between certain relative movable stroke is arranged, when last suction nozzle cover contacts with aluminum dipping form, the rigid impact power of its generation is absorbed by spring, following matrix in following suction nozzle cover and the cover descends thereupon, has avoided the impaired phenomenon of matrix or aluminum dipping form to take place.
Description of drawings:
Accompanying drawing has been represented the structure chart of the utility model embodiment.
The specific embodiment:
With reference to accompanying drawing.
Following mold mechanism comprises lower main axis 4, and its axle center is an aspirating unit 10, overlaps 2 with following suction nozzle on it and fixedlys connected; In the last suction nozzle cover 2 sucker 3 under the rubber that communicates with aspirating unit 10 is housed, is used to hold down matrix.Upper cover plate 1 is fixedlyed connected with bearing holder (housing, cover) 7, the bearing holder (housing, cover) 7 outer bearing spiders 8 that are provided with, and its upper end has 4 symmetrical blind holes, respectively places helical spring 6 in the hole; One liftout plate 11 is installed above the bearing spider 8, and helical spring 6 upper ends are run through liftout plate and are pushed up mutually with upper cover plate 1 lower surface.When last suction nozzle cover 2 presses down suction nozzle and overlaps 2 by aluminum dipping form (not drawing among the figure); its impact is absorbed by helical spring 6 by upper cover plate 1; following suction nozzle cover 2 has a downward buffering course by upper cover plate 1 compression spring 6, thereby has protected time matrix or aluminum dipping form not to be damaged.
Claims (2)
