Description
Technical field
The utility model relates to a kind of contact lenses building mortion, and particularly a kind of mode with the pivot shaping dies is produced the plane formula contact lenses building mortion of eyeglass.
Background technology
Wearing of contact lenses can bring the user appearance attractive in appearance, and is convenient to the user and is engaged in activities such as various motions, therefore gains great popularity.The eyeglass production of contact lenses is earlier a liquid material to be inserted in the shaping dies, again this liquid material is formed processing with dry solidification, to obtain required the eyeglass external form and the number of degrees.For example, this shaping dies is driven by a motor and pivots, and makes this liquid material form an eyeglass external form, and the curing that further is dried, thereby forms a solid-state eyeglass.
See also illustrated in figures 1 and 2ly, known contact lenses building mortion comprises a board 71, a rotating shaft 70, a vertical type sleeve 72, a driving mechanism 73 and a plurality of quartz burner 74.This rotating shaft 70 is articulated in this board 71 and is provided with an axial passage 701.An axial passage 721 made and is provided with by this sleeve 72 by light transmissive material.This sleeve 72 is fixed in the top of this rotating shaft 70, and the passage 721 of this sleeve 72 is communicated in the passage 701 of this rotating shaft 70.This driving mechanism is connected in the bottom of this rotating shaft and drives this rotating shaft 70 and pivots.Described quartz burner 74 be located on this board 71 and be positioned at this sleeve 72 around.The passage 721 of this sleeve 72 is in order to a plurality of shaping dies 78 of fixing within it.Each shaping dies 78 is made by light transmissive material and it is provided with a plurality of clamping pieces 781 on every side.
The production of contact lenses is to insert a liquid material earlier in each shaping dies 78.Then, described shaping dies 78 is overlapped mutually, and utilize a lower push rod with described shaping dies 78 pushing tows to the passage 721 of this sleeve 72.The clamping piece 781 of each shaping dies 78 is closely tied in the inner face of this sleeve 72, makes described shaping dies 78 be immobilizated in this sleeve 72.Then, this driving mechanism 73 drives this rotating shaft 70 and pivots, and described shaping dies 78 pivots of these sleeve 72 drives, makes that the liquid materials in each shaping dies 78 form an eyeglass external form.At this moment, the light of described quartz burner 74 passes this sleeve 72 and described shaping dies 78 and shines described liquid material, makes each liquid material be accelerated dry solidification, thereby forms a solid-state eyeglass.At last, by a upper ejector pin described shaping dies 78 pushing tows are gone out the passage 721 of this sleeve 72.
In the above-mentioned known contact lenses building mortion, the light of described quartz burner 74 is via the refraction of this sleeve 72 and described shaping dies 78 and reflection and shine described liquid material, causes the intensity of described quartz burner 74 light to be weakened and inhomogeneous.Therefore, this contact lenses building mortion can't shorten the required time that eyeglass is shaped effectively, and can reduce the accuracy of the eyeglass number of degrees, and the disqualification rate that makes eyeglass be shaped increases.
