Into the bottom surface of first mould, to form the word or symbol 12, and the word or symbol 12 are
Continuously, not with a kerf or opening, to avoid ejection formation after the word or symbol 12 occur
A kerf or opening.
In the step 6, second mould is taken out, that is, forms a cap 20 of the second color of tool,
The word or symbol of first color is formed on the surface of cap 20 of second color, and the cap
One side of lid 20 has a salient point 21；Wherein, in the step 4, by the second colored plastic Jing
When being injected in the groove of second mould by the second material filling hole, second colored plastic will along this
Gap above the word or symbol of one colored plastic is injected in the groove, and the second colored plastic is filled out
The periphery and the groove of the full word or symbol 12, to form a cap 20 of the second color of tool, and
The word or symbol 12 of first color is formed on the surface of cap 20 of second color, and should
One side of cap 20 has a salient point 21, and the salient point 21 is the fill orifice of second colored plastic.
Additionally, the manufacture method of the double-colored keycap of the light-permeable of the present invention further has：There is provided one the 3rd
Mould, and the 3rd mould is placed in into first die inside, and second colored plastic is injected
In 3rd mould, the step of to form a cap post 30.
Therefore, by the present invention the double-colored keycap of light-permeable manufacture method manufactured by double-colored keycap its
With following advantages：1st, its second colored plastic is injected by side, and second colored plastic is by edge
The gap above the word or symbol of first colored plastic to inject in the groove, by the second color
Plastics fill up the periphery and the groove of the word or symbol 12, to form a cap of the second color of tool
20；2nd, there are multiple thin ribs 11 on its sheet frame 10, and the front of the plurality of thin rib 11 has
At least one continuous word or symbol 12, the thin rib 11 will not be kept off to a backlight (not shown),
Make the light source of word on the surface of keycap 20 or symbol 12 evenly and clearer and more definite；And 3, its cap
Word or symbol 12 on lid 20 does not have otch, and word or symbol more attractive in appearance can be presented during printing opacity.
Therefore, the double-colored keycap manufactured by the manufacture method of the double-colored keycap of light-permeable of the invention really compared with
The double-colored keycap of light-permeable of known technology has progressive.
Additionally, the present invention also provides a kind of light-permeable double-colored keycap.Please with reference to Fig. 6 and Fig. 7,
Wherein Fig. 6 illustrates the decomposing schematic representation of the double-colored keycap of light-permeable of another preferred embodiment of the invention；Figure
The combination of the 7 double-colored keycaps of light-permeable for illustrating another preferred embodiment of the invention and a switch base is illustrated
Figure.
As illustrated, the double-colored keycap of light-permeable of another preferred embodiment of the invention includes：One sheet frame 10；
One cap 20；And one cap post 30 combined form.
Wherein, the sheet frame 10 has one first color, and thereon with multiple thin ribs 11, and this is more
The front of individual thin rib 11 has an at least word or a symbol 12, and the word or symbol are for continuous
And do not have a kerf.Wherein, first color is light-permeable color, such as but not limited to red,
Pink, green or blue, the quantity of the plurality of thin rib 11 is such as, but not limited at least three,
And the word or symbol 12 are continuous, to avoid ejection formation after the word or symbol 12 occur one
Otch or opening.
The cap 20 has one second color, and the word or symbol 12 are formed at the cap 20
Surface, to form a pair of chroma key cap.Wherein, second color is such as, but not limited to black or white,
And its side has a salient point 21, the salient point 21 is plastics fill orifice.
The cap post 30 also has second color, the lower section of sheet frame 10 is placed in, to switch with one
Seat 40 is combined, and has a backlight 41 on the switch base 40, and the backlight 41 for example but is not limited
In for a light emitting diode.
As shown in fig. 7, after combination, when the double-colored keycap is pressed, on the switch base 40
Backlight 41 can be enabled and send a light source, and the light source can penetrate word or symbol of the first color
Numbers 12 and be presented in the surface of the cap 20.And because having multiple thin ribs 11 on its sheet frame 10,
The thin rib 11 will not keep off the light source that the backlight 41 is sent, and make the text on the surface of keycap 20
The light source of word or symbol 12 is evenly and clearer and more definite；And the word or symbol 12 on its cap 20
There is no otch, word or symbol more attractive in appearance can be presented during printing opacity.Therefore, it is of the invention can
The double-colored keycap of printing opacity has progressive compared with the double-colored keycap of the light-permeable of known technology really.
It is disclosed, it is one kind of preferred embodiment, the change or modification of every local and source
It is that the people for being familiar with the technology is easy to what is deduced in the technological thought of the present invention, does not all take off the present invention
Claim categories.
