Description
Technical field
The utility model is related to input equipment field, more particularly to a kind of keycap, and the mould for preparing the keycap.
Background technology
The keycap of existing keyboard is divided into five kinds：1st, double-shot moulding keycap, with Colour selection is abundant, character can transparent
The characteristics of light, never wornout super wear-resisting, character, low cost, one technique productions of double coloured plastic injection machine；2nd, radium-shine material is molded, then
Laser carving character, this kind of keycap feature：Low cost, color are limited by laser carving technique, color is single, wearability is general, can not do word
Symbol is luminous, and existing not illuminated keyboard is commonly used；3rd, injection moulded clear material, laser carving hollow character again after spray painting, this kind of keycap feature：Cost
It is high, color is limited by laser carving technique, color is single, not environmentally, old-fashioned illuminated keyboard use is gradually substituted；4th, keycap is molded, then
Silk-screen character, this kind of keycap feature：High cost, rich color, not environmentally, character luminous can not be done, worn no resistance, it is old-fashioned not send out
Light keyboard is used, and is gradually substituted；5th, heat sublimation（Contaminate）Character keycap, this kind of keycap feature：Injection keycap after contaminate again, cost
Very high, rich color, gloss is gorgeous, not environmentally, can not to do character luminous, wearability good, few to commemorate that version keyboard is used.
With computer and the development of network game, computer game players all pursue a super abrasive, character luminous, rich color
Keyboard.Double-shot moulding keycap reaches such requirement, so now double-shot moulding keycap gamepad is computer game player
First-selected keyboard.But existing double-shot moulding closes character keycap, transparent confinement character（Such as capital B, D, O, numeral 6,8,
9th, 0 etc.）The second middle color isolated island glue position need have the second color filling channel with the second color main gel position, and the second color can just entered
Glue main body is packed into the second color isolated island glue position by the second color filling channel.So close the luminous of character and be left with the second color
The shade of filling channel.It is illustrated in figure 1 the structure of existing double-shot moulding keycap, a therein is the second color isolated island glue position, b
For the second color main gel position, c is the first color light emitting host, and d is to connect filling out for the second color isolated island glue position and the second color main gel position
The the second coloring agent material filled after the solidification retained in passage, e is the optical waveguide layer being connected with the first color light emitting host c.The institute in figure
In the structure shown, the second coloring agent material d is located at the lower section of the first color light emitting host c, when the light source luminescent in keycap, second
Coloring agent material d will produce obstruct to the opticpath of light source, and the first color light emitting host c above the second coloring agent material d will not
On the opticpath of light source, this will cause the first color light emitting host c being located above the second coloring agent material d to produce shade.
Can be on the downside of keycap for if the character that capital B and numeral 8 so have two the second color isolated island glue positions
Two the second color filling channels are left, the shade observed from above keycap will be apparent from.This have a strong impact on illumination effect and
The integrality of character and attractive in appearance.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, there is provided one kind closing character is complete
The unblanketed double-shot moulding keycap in whole, attractive in appearance, luminous zone.
Second purpose of the present utility model is to provide a kind of simple structure, easy to operate, low cost and can realize that keycap is sent out
The unblanketed keycap in light area prepares mould.
The technical scheme that keycap described in the utility model is adopted is：It includes the second color isolated island master in closing character
Body, the periphery of the second color isolated island main body surrounds the first color printing opacity main body for constituting closing character, the first color printing opacity
Main body periphery is provided with the second color profile main body, and on the downside of the second color isolated island main body the first color light conductor is provided with,
The first color printing opacity main body is with the first color light conductor integrated injection molding and is formed without intercepting guide-lighting light path, described second
