Abstract

The invention relates to a preparation method of a snap-carrying fiber decoration part. The preparation method contains mold design and manufacture, fiber cloth laying and demolding, and is characterized in that an elastomer is additionally arranged at a snap position of a mold during the mold design and manufacture, or the mold is broken down into a product body mold block and a snap mold block; during molding, the product body mold block and the snap mold block are tightly locked on a same upper mold; and during demolding, unlocking is carried out, and the product body mold block and the snap mold block respectively undergo demolding so as to obtain the product. According to preparation of the snap-carrying fiber decoration part, the elastomer is additionally arranged at the snap or groove position during mold design and manufacture, or the mold is broken down. Thus, the snap is prevented from being broken. In addition, demolding is easy and simple to operate and will not influence apparent quality of the product. By the above preparation method, one-time forming of the snap-carrying decoration part is realized, production technology is simplified, costs are reduced, and precision and efficiency of the product are raised.

Description

A kind of preparation method with buckle fiber decoration
Technical field
The present invention relates to a kind of preparation method of carbon fiber product, particularly relate to a kind of preparation method with buckle fiber decoration.
Background technology
The manufacture craft of existing carbon fiber product, be usually difficult to realize integrated molding, the decoration of particularly small buckle, is mainly reflected in: 1, in Design of Dies, and it is shaping that difficulty realizes click-on design, can only make the decoration of some simple shapes; 2, the difficult demoulding after shaping, or after the demoulding, product buckle is broken.Therefore, the decoration of existing band buckle is all adopt separately shaping mode usually, and then is bonded on decoration by buckle.This mode easily occurs that bonding site misplaces, bonding insecure, and the phenomenon such as easily come off, and precision is low, and length consuming time, efficiency is low.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, provide one to realize one-body molded, simplify production technology, reduce costs, improve the preparation method of the band buckle fiber decoration of precision and efficiency.
The technical scheme taked for realizing object of the present invention is:
With a preparation method for buckle fiber decoration, comprise Design of Dies processing, the laying of fiber cloth and stripping forming, is characterized in that described Design of Dies adds man-hour, adds elastomer in the buckle site of mould.
Described elastomer adopts plastics, rubber, silica gel or polyurethane material to make.
A kind of preparation method with buckle fiber decoration, comprise Design of Dies processing, the laying of fiber cloth and stripping forming, it is characterized in that described Design of Dies adds man-hour, mould is split into product ontology mold block and buckle mold block, time shaping, product ontology mold block and buckle mold block are lock onto on same mold, unlock during the demoulding, by product ontology mold block and the demoulding respectively of buckle mold block, obtain product.
Adopt the fiber cloth of several unlike material to carry out mixing laying at the privileged sites of product, the privileged sites of described product are Signal reception point or signal launch point.
Described fiber cloth is carbon cloth, boron fibre cloth, basalt fiber cloth or glass fabric.
The overlay thickness of described fiber cloth is 1-5 layer.
Described stripping forming adopts VA RTM shaping.
The preparation of band buckle fiber decoration of the present invention, elastomer is added in its buckle site by adding man-hour at Design of Dies, or mould is split, thus prevents buckle to rupture, and the demoulding is easy, simple to operate, the apparent mass of product can not be had influence on, achieve the one-shot forming of band buckle decoration, simplify production technology, reduce cost, improve precision and the efficiency of product.
Accompanying drawing explanation
Fig. 1 is the processing simplified schematic diagram of mobile phone shell.
Detailed description of the invention
Below in conjunction with example, the specific embodiment of the present invention is elaborated.It should be understood that example is for illustration of the present invention instead of limitation of the present invention.Scope of the present invention and core content are determined according to claims.
The preparation method of band buckle fiber decoration of the present invention is:
1, the design processing of mould: 3D design data, CNC processes with regard to mould.On mould, design has the die cavity of buckle and product ontology, realizes integrated molding.Simultaneously, during in order to prevent shaping and demoulding, small, complex structure buckle is easily broken, form removal difficulty, misoperation affects the defect of product apparent mass, solution of the present invention is: add elastomer to buckle site on mould, and this elastomer adopts plastics, rubber, silica gel or polyurethane material to make.Generally, because mould is hard material, the external force during demoulding is easy to broken by small buckle disconnected or produce damage, and the present invention adds elastomer in buckle site, and the phenomenon utilizing elastomeric elastic force effect that buckle just can be avoided to rupture occurs.
The present invention is in order to solve the problem of buckle fracture, also take mould to be split into product ontology mold block and buckle mold block, then when shaping, product ontology mold block and buckle mold block are lock onto on same mold, unlock during the demoulding, product ontology mold block and buckle mold block are distinguished the method for the demoulding, the method not only can avoid buckle to rupture, and achieves disposal molding again simultaneously.Mobile phone shell as shown in Figure 1, counterdie is divided into lower module 2, sub-module I 4 and sub-module II 3, upper module 1 is provided with dowel hole position 5, sub-module I 4 has pin-and-hole, mobile phone shell 6 is provided with chamfering (in figure, 7 is buckle), time shaping, the cooperation of the pin-and-hole on the cooperation of each sub-unit and dowel hole position 5 and sub-module I 4 is utilized to be locked on upper module 1 by each several part, and matched moulds.
2, the laying of fiber cloth and stripping forming, comprise according to the position matched moulds shown in Fig. 1,
1) reduce the fiber cloth of required present situation size and weigh good required component resin-based;
2) fiber cloth superposition is laid in the die cavity of bed die, by upper and lower mould matched moulds, locking;
3) then preforming tool is vacuumized, then toward resin by injection base in die cavity, wetting fibre cloth;
4) last normal temperature cure or at the 40-50 DEG C of 2h(that is heating and curing in order to raise the efficiency), stripping forming after completion of cure.
Fiber cloth is one or more in carbon fiber, boron fibre, basalt fibre or glass fibre.During laying, at the privileged sites of product, Signal reception point, signal launch point etc. as mobile phone shell, television cabin etc. adopt the fiber cloth of several unlike material to carry out mixing laying, and overlay thickness is 1-5 layer, is that product not only meets requirement of strength but also can realize " thin " light-weight requirements attractive in appearance.
5) stripping forming adopts VA RTM shaping, and vacuum is 1 vacuum.
