Abstract
A kind of manufacturing method of material shell includes a material preparation step and a molding and demoulding step.It is that multilayer is stacked with into a base material, and mould release is added in the resin containing the carbon fibre initial rinse material for being soaked with resin in the material preparation step.It is that the base material is placed in a mold in the molding and demoulding step, and a material shell is made after hot-forming and demoulding.Being added to the resin of mould release can make the material shell be easy to demould.It is added in resin when refining glue by by mould release, is easy to demould after molding can be made, and be not required in addition in spraying mould release on mold, also be not required to carry out blasting treatment to the surface of material shell, product yield can be promoted so as to reduce abrasion.
Description
Technical field
The present invention relates to a kind of manufacturing method of shell, more particularly to a kind of system for the material shell for being easy to demoulding
Make method.
Background technology
At present industry production material shell normal method be：By multiple carbon fibre initial rinse material phases added with resin
A base material mutually is stacked into, then mould release is sprayed on a mold, then places the substrate in the mold, makes mould release
Between mold and base material.Finally to the mold carry out it is hot-forming and by the substrate forming be a material shell.Though
Right mould release helps to demould, but during hot pressing is hardened, by the resin that is overflowed in the base material often with mould release
It attaches to jointly on mold and the material shell surface, it is therefore desirable to be additionally carried out lift-off processing.When the residue sticked is difficult
During with by removing on the material shell, just need to carry out blasting treatment to the material shell, in favor of residual by what is sticked
Slag is removed, and not only process is more for such manufacture, and blasting treatment easily causes to grind to the slight part of the material shell
Damage reduces yield and influences product appearance.
Invention content
Material shell is made to be easy to demould the purpose of the present invention is to provide one kind and be not required in addition to spray mould release and
The manufacturing method of sandblasting.
The manufacturing method of material shell of the present invention includes a material preparation step and a molding and demoulding step；Its
It is characterized in that：In the material preparation step, multilayer is stacked with into a base material, and should containing the carbon fibre initial rinse material for being soaked with resin
Added with mould release in resin, in the molding and demoulding step, which is placed in a mold, and through hot-forming and
A material shell is made after demoulding.
Preferably, the manufacturing method of aforementioned material shell, wherein in the material preparation step, which is thermosetting property tree
Fat.
Preferably, the manufacturing method of aforementioned material shell, wherein in the material preparation step, resin is to be added to
The mould release of 1wt%.
Preferably, the manufacturing method of aforementioned material shell, wherein in the molding and demoulding step, which includes
One mold for surrounding out die cavity and a lower mold formed there are one module, the base material are placed in the lower mold
Module on, and when the lower mold and the mold pairing, which can be squeezed into the die cavity by the module.
Preferably, the manufacturing method of aforementioned material shell, wherein in the molding and demoulding step, it is hot-forming
Temperature is Celsius 140 to 160 degree.
The beneficial effect of the present invention is：By the way that mould release is added in when refining glue in resin, it is easy to after molding can be made
Demoulding, and be not required in addition in spraying mould release on mold, also be not required to carry out blasting treatment to the surface of material shell, so as to
It reduces abrasion and product yield can be promoted.
Description of the drawings
Fig. 1 is a flow chart, illustrates one embodiment of the manufacturing method of material shell of the present invention；
Fig. 2 is a schematic diagram, illustrates a material preparation step of the present embodiment；And
Fig. 3 is a schematic diagram, illustrates a molding and demoulding step of the present embodiment.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Refering to Fig. 1, one embodiment of the manufacturing method of material shell of the present invention, comprising a material preparation step 11,
And one molding and demoulding step 12.
It is by the mutual heap as illustrated in fig. 2 of multilayer carbon fibre initial rinse material 2 in the material preparation step 11 refering to Fig. 1 and Fig. 2
Build up a base material 3.Each layer of carbon fibre initial rinse material 2 is to contain to be soaked with thermosetting resin, and resin is just added with when refining glue
Mould release.In the present embodiment, which is epoxy resin, and is added with the mould release of 1wt%.Certainly, mould release can also
It is just to be added in resin after refining glue, is not limited.
It is to prepare a mold 4, which encloses including one in the molding and demoulding step 12 refering to Fig. 1 and Fig. 3
Lay out the mold 41 and a lower mold 42 formed there are one module 420 of a die cavity 410.The base material 3 is placed under this
It is then that the mold 41 and lower 42 pairing of mold is hot-forming to carry out in the module 420 of mold 42, in hot-forming mistake
Cheng Zhong, the base material 3 are squeezed into the die cavity 410 by the module 420 and form mold state, and a composite wood can be made after demoulding
Expect shell 5.In the present embodiment, which is 140 degree Celsius to 160 degree Celsius, and by designing the mold
4, required feature 51 can be processed on the material shell 5, the feature 51 of the present embodiment is with to the folding of the recessed folding in both sides
For side, but not limited to this.
Although when the base material 3 is squeezed, has part resin and overflow, due to containing mould release in resin, no
It can be built-up on mold 4, conducive to demoulding, and be not required in addition spray mould release or sandblasting, process can be reduced and product is avoided to wear.
In conclusion being added in resin when refining glue by by mould release, material shell 5 can be made to be easy to after shaping
Demoulding, and be not required in addition in spraying mould release on mold 4, also be not required to carry out blasting treatment to the surface of material shell 5, it can
It avoids wearing and being promoted product yield, therefore the purpose of the present invention can be reached really.
