Multilayer eyeglass is prepared referring to the method and step of embodiment 1.
Analysis detection:
1, comparative example 1
The mold of comparative example 1 has the following problems during preparing eyeglass:
(1) when the first layer of replaceable second half module 21 of separation first and multilayer eyeglass, the traction force of generation will lead to half
The first layer of solid multilayer eyeglass is disconnected with third half module 50, and then subsequent operation is caused to be not easy to carry out.Therefore, to keep away
Exempt from above situation appearance, need when separation greatly patient with careful operation, wastes time and energy.Experiment discovery, 20
It is secondary to repeat in experiment, comparative example 1 can be separately separated the success rate of the first layer of the multilayer eyeglass of the second half module and semisolid compared with
It is low, about 5%.
Volume contraction, such as average shrinkage ratio about 10% are had after the solidification of (2) first curable liquids.Above-mentioned contraction can be led
The first layer and 510 edge of third die cavity face for causing the multilayer eyeglass of semisolid generate gap.Then, when the multilayer to semisolid
When first layer surface of eyeglass applies the second curable liquid, the second curable liquid cognition passes through above-mentioned gap penetration to mould
Between the first layer and third half module of product processed, such as the front surface of the first layer of molding product is penetrated into, causes to mould product
The surface of first layer towards third half module be destroyed.
Experiment discovery, in 20 repetition experiments, the second curable liquid can penetrate into the first of molding product every time
The front surface of layer, leading to the yields of product is zero.

Sealed connection is generated with the first layer of multilayer eyeglass.Before making the impermeable first layer to multilayer eyeglass of the second curable liquid
Surface.
The volume contraction of the first layer of multilayer eyeglass after shaping makes to generate compression between the first half module 10 and multilayer eyeglass
Connection.The leakproofness that the compression link enhancement is tightly connected.
The setting of third groove 113 makes to generate clamping connection, the card between the first half module 10 and the first layer of multilayer eyeglass
The first layer of multilayer eyeglass when on the one hand the first replaceable second half module 21 being avoided to separate with the first layer for moulding product is connect in succession
It keeps connecting with the first half module, on the other hand clamping connection also enhances the leakproofness of sealed connection.
Experiment discovery:
(1) in 20 repetition experiments, embodiment 1 can be separately separated the of the multilayer eyeglass of the second half module and semisolid
One layer of success rate is 100%.
(2) in 20 repetition experiments, the second curable liquid will not penetrate into the front surface of the first layer of molding product,
The yields of product is 100%.
The above comparative illustration, the mold and index method of embodiment 1 have the advantages that following one or more:
