Abstract
The invention discloses a kind of soft mold and its manufacture method for composite product, including plasticity material sandwich layer and top layer, top layer is brought into close contact with sandwich layer, top layer envelopes sandwich layer, and the surface material is polypropylene film, simultaneously bright and clean, another side has viscosity, and adhesive faces are contacted with sandwich layer.It is softer before soft mold sizing of the present invention, with plasticity, there is certain deformability in the presence of external force, and plasticity declines after shaping, elasticity rises, therefore various shapes can be fabricated to, can be widely applied to the pressure transmission in the place such as R angles, V angles, U angles during composite product vacuum solidification.
Description
Technical field
The present invention relates to a kind of soft mold and its manufacture method.
Background technology
During current composite product vacuum assisted resin infusion, because former R angles are easily built bridge, it is impossible to be stressed, product R
The easy loose or rich resin in angle, and formpiston R angles unbalance stress（It is excessive）, the problems such as cause product R angles thickness excessively thin, influence product matter
Amount.
The content of the invention
Composite product vacuum aided is solved it is an object of the invention to provide a kind of soft mold and its manufacture method
Present in forming process the problems such as bridge formation or stress are excessive causes loose R angles, rich resin or excessively thin thickness.
The present invention solve its technical problem concrete scheme be：
A kind of soft mold for composite product, including plasticity material sandwich layer and top layer, top layer is closely pasted with sandwich layer
Close, top layer envelopes sandwich layer, and the surface material is polypropylene film, simultaneously bright and clean, and another side has viscosity, adhesive faces and core
Layer contact.
The sandwich layer material is synthetic rubber.
A kind of manufacture method of the soft mold for composite product,（1）Appropriate sandwich layer is taken according to demand：Sandwich layer width
For R angles girth+（0~4）Mm, core layer length be composite product length+（0~4）Mm, if soft mode is used cooperatively with equal pressing plate
When, core layer thickness is approximately equal to equal thickness of compressive plate, and sandwich layer is fabricated to the blank of required shape；（2）Blank is coated with top layer, is wrapped
The sticking one side in top layer is contacted with blank when covering, and is brought into close contact with blank, should not there is bubble, and top layer should not after being covered to complete
Have a fold, and top layer overlap joint place not with product into contact；（3）The blank that will have been coated is placed on mould, and blank both sides are placed
Postive stop baffle, in order to avoid pellet deformation is excessive in type-approval process, shapes under 120 DEG C ~ 150 DEG C and an atmospheric pressure；（4）After cooling
The demoulding, then soft mold making is finished.
The beneficial effects of the invention are as follows：
First, it is softer before soft mold sizing, with plasticity, there is certain deformability in the presence of external force, and shape
Plasticity declines afterwards, and elasticity rises, therefore can be fabricated to various shapes, can be widely applied to composite product vacuum solidification process
The pressure transmission in the place such as middle R angles, V angles, U angles；
2nd, the skin surface of the soft mold is bright and clean, stable chemical performance, chemistry does not occur instead with sandwich layer, fiber, fabric, resin
Should；
3rd, the soft mold sandwich layer and top layer thermal coefficient of expansion are all smaller, sandwich layer have it is more small, therefore in composite product
Smaller is influenceed on product size in heat curing process, can be used for the moulding process of some multi-cavity structures；
4th, the soft mold can be made by hand, can be shaped under uniform temperature and pressure.

Specific embodiment
It is described in further detail to of the invention below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
The embodiment.
Such as Fig. 1, sandwich layer 1 and the top layer 2 of a kind of soft mold for composite product, including plasticity material, top layer
It is brought into close contact with sandwich layer, top layer envelopes sandwich layer.The surface material is polypropylene film, simultaneously bright and clean, and another side has viscous
Property, adhesive faces are contacted with sandwich layer.
The manufacture method of soft mold includes（1）Appropriate sandwich layer is taken according to demand：Sandwich layer width be R angles girth+（0~4）Mm,
Core layer length be composite product length+（0~4）Mm, if soft mode is used cooperatively with equal pressing plate, core layer thickness is approximately equal to
Thickness of compressive plate, sandwich layer is fabricated to the blank of required shape；（2）Blank is coated with top layer, top layer sticking one during cladding
Face contacts with blank, and is brought into close contact with blank, should not there is bubble, and top layer should not have fold after being covered to complete, and top layer overlaps
Place not with product into contact；（3）The blank that will have been coated is placed on mould, and postive stop baffle is placed in blank both sides, in order to avoid sizing
During pellet deformation it is excessive,（120~150）DEG C and an atmospheric pressure under shape；（4）The demoulding after cooling, then the soft mold system
Finish, can come into operation.
Such as Fig. 3, during use, the R angular contacts of soft mold and composite product 3 can uniformly transfer pressure, and can keep away
Exempt from arch formation.
Such as Fig. 4, during use, the R angular contacts of soft mold and composite product 3, respectively there are equal pressing plate 4, soft mode in left and right
Tool can uniformly transfer pressure, and be avoided that arch formation.
The above, for the person of ordinary skill of the art, can be with technology according to the present invention scheme and technology
Other various corresponding changes and deformation are made in design, and all these changes and deformation should all belong to appended right of the invention
It is required that protection domain.
