Description
Technical field
The present invention relates to a kind of impressing mould, relate in particular to a kind of impressing mould that is applicable to impression micron order element.
Background technology
When manufacturing dimension is the element of micron order (common several microns to the hundreds of micron), if on the impression face of impressing mould, offer steam vent, then the precision of impressing mould reduces, and, also on product, stay the vestige of steam vent easily, make impression transcription rate reduce, therefore, the impression face of this kind impressing mould generally is not provided with steam vent.But,, be easier to take place gas explosion, operational hazards if non air exit hole can make the gas in the die cavity in time to discharge.
Summary of the invention
In view of this, be necessary to provide a kind of impressing mould that can exhaust influence the transcription rate again.
A kind of impressing mould, this impressing mould is used for impression and makes the micron order element, it comprises forming surface, this impressing mould has an exhaust duct and a ventilated element, this exhaust duct has an opening that is positioned at this forming surface, and this exhaust duct leads to the outside of this impressing mould, and this ventilated element seals the opening of this exhaust duct so that this forming surface is complete, this ventilated element is a nano-cloth, so that gas is discharged through this exhaust duct.
With respect to prior art, impressing mould provided by the invention has exhaust duct, this exhaust duct is communicated with inside and outside the impressing mould, ventilated element seals the opening that this exhaust duct is positioned at forming surface, gas in the mould is discharged through exhaust duct, on the one hand fill up this opening and makes the forming surface surface more complete, thereby alleviate even eliminate exhaust duct and stay vestige on the product because of ventilated element.

The specific embodiment
See also Fig. 1 and Fig. 2, the impressing mould 10 that the embodiment of the invention provides is used to make the micron order eyeglass, promptly lens dimension at several microns between the hundreds of micron.
Impressing mould 10 has a land area 100, and this land area 100 is formed with a plurality of forming areas 20, and each forming area 20 is used for eyeglass of moulding.In the present embodiment, each shaped region 20 has the forming surface 201 of die face 100 depressions that are involutory, and is used to form a convex eyeglass opposite with these forming surface 201 shapes.Each forming surface 201 limits a molding space.
Each forming surface 201 offers an exhaust duct 30.This exhaust duct 30 has one first opening 31 and one second opening 32, and this first opening 31 is positioned at this forming surface 201.In the present embodiment, this exhaust duct 30 runs through this impressing mould 10, and this second opening 32 is positioned at the opposite bottom surface of this impressing mould 10 and forming surface 201.This second opening 32 can also be positioned at other surface of this impressing mould 10, and for example the side only needs the outside that this exhaust duct 30 leads to this impressing mould 10 to get final product.Preferably, the aperture of this exhaust duct 30 is generally 1 micron and gets final product between 0.5 micron to 1.5 microns.
This exhaust duct 30 is positioned at the central authorities of each forming surface 201 of impressing mould 10, certainly, also can be positioned at the position away from central authorities of each forming surface 201.
This impressing mould 10 also comprises a ventilated element 40, these ventilated element 40 these first openings 31 of sealing.Preferably, the shape of this ventilated element 40 is identical with the shape of this first opening 31, makes this forming surface 201 smoothly complete, further alleviates the impression vestige that first opening 31 may stay when shaped article on the product, improves mould and die accuracy and transcription efficient.
Ventilated element 40 is a nano-cloth, promptly scribbles nano material or is inlaid with the textile of nano material, for example is inlaid with the polyester fiber of nano silicon.The size of nano material usually in several nanometers between the hundreds of nanometer.Because textile itself has hole, after nano silicon adheres to or is embedded in this textile, make the hole of textile dwindle and to guarantee that gas passes through, also can stop moulding material (figure do not show) to flow into exhaust duct 30 simultaneously, and this ventilated element 40 is suitable to be difficult for being deformed into.Therefore, moulding material can be limited in the molding space fully, does not influence the effect of imprinting moulding, and the gas in the molding space can be discharged, and guarantees production safety.
Depend on the shape of this ventilated element 40 and the matching degree of forming surface 201 on the high lower part degree of impression transcription rate.Ventilated element 40 makes the shape of forming surface 201 level and smooth more, and then transcription efficient is more high.
See also Fig. 3, the method for imprinting moulding eyeglass may further comprise the steps: a substrate 50 is provided, and these substrate 50 surfacings also can adopt the mould with another forming surface to cooperate this impressing mould 10; In these substrate 50 surface coating impression materials, impression materials can be covered on this substrate 50 equably, also can be Zone coated according to the impression position; Impressing mould 10 is aimed at this substrate 50, and especially, a forming surface 201 is aimed at a predetermined shaping position; Then, impressing mould 10 is pressed on this substrate 50, thereby forming surface 201 and substrate 50 form a molding space 70, impression materials is full of this molding space 70; Solidify this moulding material, because this impressing mould 10 has exhaust duct 30, therefore this molding space 70 be ventilated mutually with the impressing mould 10 outer ventilated elements 40 that can pass through, and the shape of ventilated element 40 is identical with the shape of this first opening 301, so can not influence the shape of product; After curing is finished, remove this impressing mould 10, obtain the planoconvex eyeglass.
The shape of the forming surface of impressing mould 10 is not limited to shown in the present embodiment, but no matter the shape of forming surface why, exhaust duct 30 is with 10 inside and outside connections of impressing mould, and the opening 31 that exhaust duct 30 is positioned on the forming surface 201 is sealed by ventilated element 40, therefore, not only can alleviate even eliminate the influence of 31 pairs of products of opening but also can reach exhaust effect.
The structure of impressing mould is not limited to shown in the embodiment of the invention, can also be the impressing mould of the concavees lens of making micron order even smaller szie, optical filter etc.
Be understandable that those skilled in the art also can do other variation in spirit of the present invention, all should be included within the present invention's scope required for protection.
