Abstract
Include the flashlight idiosome being made by PC materials the utility model discloses a kind of flashlight housing, on the flashlight idiosome hot pressing have the film sheet of one layer of PP material；The inner surface of the film sheet is printed with decorative pattern and word；The thickness of the film sheet is between 0.1 0.8mm；Hot pressing workpiece is consistent with the dimensional fits of injection-molded work, and film sheet and flashlight idiosome will not occur the corrugated ill effect of product surface in injection molding, improves the qualification rate and presentation quality of product.Also, two kinds of materials can be welded together completely in injection molding, it is ensured that product not delamination after injection molding.
Description
Technical field
The utility model is related to a kind of flashlight, especially a kind of flashlight housing.
Background technology
Flashlight housing on the market is typically to be produced using PC materials at present, and people preferably decorate in order to obtain
Effect usually covers a kind of decorating film sheet material in flashlight housing, but because of piece in process " injection molding " process
Material is different from the Material texture of base material, leans on adhesive bonding between the two, the coefficient of expansion of two kinds of materials when being heated or being cooled
Difference causes film sheet to may possibly be separated with workpiece, to which the use to product brings risk；In addition when sheet material and base material material not
When identical, during " hot-forming ", hot-die and injection mould shrinking percentage are inconsistent, to cause hot pressing workpiece and injection molding work
The dimensional fits of part can not stable and consistent, for example, the tolerance issues up and down or film sheet and workpiece that often occur are being molded into
The phenomenon that will appear product surface corrugation when type, the qualification rate of injection molding is caused to substantially reduce, overall cost is sharply increased.Add
On, traditional film sheet, need to also be in pattern ink in process first by the graphic-print being pre-designed after film surface is to be dried
A kind of transparent adhesive of layer surface brushing, it is therefore an objective to ink layer and moulding resin are subjected to glue company, but the product after glue company is simultaneously
It cannot be guaranteed its not delamination, such adhesive is completely dependent on import and expensive, and increases its manufacturing cost.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of flashlight housing, effectively prevent film sheet
The phenomenon that being detached with workpiece reduces the fraction defective of product after injection molding, improves production efficiency.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of flashlight housing, includes the flashlight idiosome being made by PC materials, hot pressing on the flashlight idiosome
There is the film sheet of one layer of PP material；
As a modification of the embodiment above, the inner surface of the film sheet is printed with decorative pattern and word；
It is further improved as to the above embodiment, the thickness of the film sheet and flourescent sheet is 0.1-0.8mm
Between.
The lever position of the flashlight idiosome, which is reserved with, inlays position, inlays and is inlaid with flourescent sheet on position, flourescent sheet and film
Sheet surface is concordant.
The hot pressing temperature is controlled at 90~120 DEG C；The hot pressing is controlled with pressure in 2.5~4.5MPa/cm2；
The hot pressing continues 5~10 minutes.
The utility model has the beneficial effects that：This product since flashlight idiosome and film sheet use similar material,
When being heated or being cooled, the coefficient of expansion of two kinds of materials is also identical, therefore is not in that film sheet shows with what flashlight idiosome detached
As greatly reducing the fraction defective of product after injection molding in this way, improving production efficiency, in addition, also so that in production process
The shrinking percentage of hot-die and injection mould is completely the same, can be fully solved in this way hot-die and injection mould up and down tolerance the problem of,
Hot pressing workpiece is consistent with the dimensional fits of injection-molded work, and film sheet and flashlight idiosome will not occur in injection molding
The corrugated ill effect of product surface improves the qualification rate and presentation quality of product.Also, two kinds of materials in injection molding
Material can be welded together completely, it is ensured that product not delamination after injection molding.Moreover, scheming well in film sheet surface printing
After case, without transparent adhesive is brushed, directly it can not only lack one of manufacturing procedure in this way with injection molding, improved life
Produce efficiency.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Referring to Fig.1, a kind of flashlight housing includes the flashlight idiosome 1 being made by PC materials, the flashlight embryo
Hot pressing has the film sheet 2 of one layer of PP material on body；The thickness of the film sheet and flourescent sheet is this production between 0.1-0.8mm
Better decorative effect, the inner surface of the film sheet are printed with decorative pattern and word to product in order to obtain.
The lever position of the flashlight idiosome, which is reserved with, inlays position, inlays and is inlaid with flourescent sheet 3, flourescent sheet and film on position
Sheet surface is concordant, and the user easy to use of flourescent sheet 3 operates at night.
The hot pressing temperature is controlled at 90~120 DEG C；The hot pressing is controlled with pressure in 2.5~4.5MPa/cm2；
The hot pressing continues 5~10 minutes.
This product is since flashlight idiosome and film sheet use similar material, when heated or two kinds of materials when being cooled
The coefficient of expansion is also identical, therefore is not in the phenomenon that film sheet is detached with flashlight idiosome, greatly reduces be molded into this way
The fraction defective of product, improves production efficiency after type, in addition, also so that the shrinking percentage of hot-die and injection mould is complete in production process
Entirely unanimously, the problem of hot-die and injection mould or more tolerance can be fully solved in this way, the size of hot pressing workpiece and injection-molded work
Cooperation is consistent, and film sheet and flashlight idiosome will not occur the corrugated ill effect of product surface in injection molding,
Improve the qualification rate and presentation quality of product.Also, in injection molding, two kinds of materials can be welded together completely, can
To ensure product not delamination after injection molding.Moreover, after film sheet surface printing good pattern, without the bonding that brushing is transparent
Agent directly can not only have been lacked one of manufacturing procedure, improved production efficiency in this way with injection molding.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
