Description
Technical field
The present invention relates to notebook computer manufacturing technology field, more particularly to a kind of aluminium film in-mold decoration forming all-in-one and
Forming method.
Background technology
Electronic product updates epoch for growing in intensity, consumer to notebook computer outward appearance technique, ergonomic
It is required that also more and more higher, such as portable light and thin type, outward appearance have metal-like etc..Traditional aluminum component punching press adds plastic cement fulcra to bond
Technique, step is as follows：
1. aluminium film punch forming；
2. plastic cement fulcra injection molding；
3. aluminium stamping parts and plastic cement fulcra are bonded together using glue or gum.
There are problems in this technique：Aluminium film and plastics fulcra are molded respectively, always be there is small error and are led
Cause laminating imperfect, bring product appearance bad.Making technology is complicated, and manufacturing cost is high, and duty cycle is long.Laminating is easily damaged
Bad, material subtracts thick limited.Therefore prior art can not meet client to product lightweight and have concurrently metal-like and sense of touch it
It is required that.
Therefore, it is necessary to provide a kind of new manufacturing technology to solve the above problems.
The content of the invention
It is a primary object of the present invention to provide a kind of aluminium film in-mold decoration forming all-in-one and forming method.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of aluminium film in-mold decoration forming all-in-one, including it is mutual
The male model and master mold of phase split, the male model include the first cavity surface and the injecting glue in the first cavity surface upper shed of projection
Runner, the master mold includes the second cavity surface and some suction holes in the second cavity surface upper shed of depression, described the
One cavity surface and the second cavity surface folder force to form die cavity.
Specifically, the suction hole is gone into battle in second cavity surface arranges arrangement.
Specifically, the aperture of the suction hole is 1.2mm.
Specifically, the both sides of the master mold are provided with feed roller and discharge roller, the feed roller and discharge roller make aluminium film be close to
The master mold conveying.
Further, being provided with the master mold can be by the cutter of product trimming.
A kind of aluminium film in-mold decoration forming method, comprises the following steps：
1. convey：Under die opening state, make aluminium film that the second cavity surface is completely covered；
2. absorption positioning：Suction hole air-breathing, makes aluminium film be drawn onto on master mold and be close to the second cavity surface；
3. matched moulds injecting glue：Male model is toward master mold direction matched moulds, by injecting glue runner toward injection in die cavity, directly in aluminium film side
It is shaped to plastic cement；
4. trimming：Cut off in the surrounding of the aluminium film by injecting glue is completed, de- material forms notebook computer casing.
Using above-mentioned technical proposal, the beneficial effect of technical solution of the present invention is：
1st, the present invention not only saves processing step, improves production efficiency, and product appearance is finer, carries significantly
High yields.Because having skipped the number of assembling steps of thin part, product can be made more frivolous, with more preferable city
Field competitiveness.
2nd, feed roller and discharge roller are used for realizing the continuous conveying of aluminium film, improve the automatization level of all-in-one.
3rd, the aperture very little of suction hole, this is prevented from, and suction is excessive to suction out convex closure in aluminium film, it is ensured that product appearance.
4th, directly set cutter just to complete trimming before die sinking in master mold, save processing step, improve
Production efficiency.

Embodiment
The specific implementation present invention is described in further detail below.
Embodiment：
As shown in Figures 1 to 5, a kind of aluminium film in-mold decoration forming all-in-one of the invention, includes the male model 1 of mutual split
With master mold 2, male model 1 includes the first cavity surface 11 and the injecting glue runner 12 in the upper shed of the first cavity surface 11 of projection, and master mold 2 is wrapped
Include the second cavity surface 21 and some suction holes 22 in the upper shed of the second cavity surface 21 of depression, the first cavity surface 11 and Second-Type
The folder of Cavity surface 21 forces to form die cavity.The side of master mold 2 can make it be close to the second cavity surface using suction hole 22 come air-breathing positioning aluminium film 6
21, after matched moulds, male model 1 and the formation of master mold 2 house the die cavity of plastic cement 7, and such plastic cement 7 directly can be just molded in the side of aluminium film 6,
The notebook computer casing of gained is with regard to that can reach matching for perfect aluminium film 6 and plastic cement 7.
As shown in Figures 1 to 5, the both sides of master mold 2 are provided with feed roller 3 and discharge roller 4, and feed roller 3 and discharge roller 4 make aluminium film
6, which are close to master mold 2, conveys.The aluminium film 6 of this side uses the band of web-like, and feed roller 3 and discharge roller 4 are used for realizing aluminium film 6
Continuous conveying, improves the automatization level of all-in-one.
As shown in fig. 6, the array arrangement in the second cavity surface 21 of suction hole 22, the aperture of suction hole 22 is 1.2mm.Aluminium film
6 are originally the banding of no fluctuating, become the shape of peplos on product and need by deformation.Aluminium film 6 after deformation also has one
The more flat face of block, so needing to suck aluminium film 6 using the suction hole 22 of array arrangement.The aperture of suction hole 22 is very
Small, this is prevented from, and suction is excessive to suction out convex closure in aluminium film 6, it is ensured that product appearance.
As shown in Figures 1 to 5, being provided with master mold 2 can be by the cutter 5 of product trimming.Complete product mould in into
After type, product remain be connected on the original sheet material of aluminium film 6 or band, it is necessary to carry out trimming.Cutting knife is directly set in master mold 2
Device 5 can just complete trimming before die sinking, save processing step, improve production efficiency.
As shown in Figures 1 to 5, the job step of aluminium film in-mold decoration forming all-in-one is as follows：
1. convey：Under die opening state, aluminium film 6 is pasted master mold 1 and moved by feed roller 3 and discharge roller 4, makes aluminium film 6 cover completely
The second cavity surface of lid 21；
2. absorption positioning：The air-breathing of suction hole 22, makes aluminium film 6 be drawn onto on master mold 1 and be close to the second cavity surface 21；
3. matched moulds injecting glue：Male model 1 is toward the direction matched moulds of master mold 2, by injecting glue runner 11 toward injection in die cavity, directly in aluminium film
6 sides are shaped to plastic cement 7；
4. trimming：The surrounding that the aluminium film 6 of injecting glue will be completed using cutter 5 is cut off, and de- material forms notebook shell
Body.
This aluminium film in-mold decoration forming one function disposable plastic cement 7 that completes within a matched moulds cycle is molded, 6 pairs of aluminium film
The cladding of plastic cement 7, in addition product trimming.Processing step is not only saved, production efficiency is improved, and product appearance is more
Finely, yields is substantially increased.Because having skipped the number of assembling steps of thin part, product can be made more frivolous,
With the more preferable market competitiveness.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
