Detailed description of the invention
For making those skilled in the art be better understood from the technical solution of the utility model, with detailed description of the invention, this utility model is elaborated below in conjunction with the accompanying drawings.
Embodiment of the present utility model discloses a kind of method of injection mo(u)lding on metal shell, the plastic deformation after utilizing this manufacture method can reduce plastic cement 5 injection, and then increases the binding ability of plastic cement 5 and metal shell 1.This manufacture method comprises the following steps:
S1: as depicted in figs. 1 and 2, the outer surface inner surface at metal shell 1 is processed to form a deep gouge 2, and makes formation one between bottom and the inner surface of deep gouge 2 reserve thin-walled 3.
Owing to metal shell 1 has signal shielding effect to the antenna of notebook computer, it is therefore desirable to arrange plastic cement 5 in the position with the metal shell 1 corresponding to antenna to reduce the shielding action of the signal to antenna.And plastic cement 5 and the form connecting through employing integrated injection molding of metal shell 1, thus, the deep gouge 2 for accommodating plastic cement 5 can be offered by Milling Process.
S2: as it is shown on figure 3, inject plastic cement 5 in deep gouge 2, and make plastic cement 5 plastic forming.
S3: abolish reserved thin-walled 3.
For avoiding the reserved thin-walled 3 shielding to the signal of antenna, it is beneficial to instrument of abolishing and reserved thin-walled 3 is abolished.
Embodiment of the present utility model also discloses the manufacture method of the metal shell of a kind of notebook computer, comprises the following steps:
S10: metal shell 1 die cast.
Metal material (such as magnalium) good for ductility is put in injection mold, utilizes die casting machine to carry out the die casting base substrate with formation metal shell 1, base substrate cools down and goes de-stress with pending subsequent handling.
S20: the cooperation face of processing metal shell 1 and mating holes.
Utilize milling machine that the metal shell 1 being in green state is carried out Milling Process, so that its size coordinating face and surface quality meet coordinates requirement；Drilling machine is utilized to be holed in the surface needing boring, such as screwed hole needed for assembling.
S30: implement the above-mentioned method of injection mo(u)lding on metal shell.
S40: polishing metal shell 1.
Metal shell 1 after milling and drilling are processed would generally produce the defective workmanship such as overlap and burr; need polishing to reject these overlaps and burr; in addition; the surface quality of the metal shell 1 of die cast is bad, improves its surface quality by grinding (a kind of form of polishing) and thinks that subsequent handling lays the first stone.
S50, carries out surface process to metal shell 1.
Surface process to metal shell 1 would generally be through two procedures:
S51: the surface of metal shell 1 is carried out chemical treatment (such as predrainage, wash and have children outside the state plan ripple process etc.) to remove greasy dirt and the impurity on metal shell 1 surface, and make the surface of metal shell 1 form one layer of oxygen-proof film.
S52: spray treatment.
The effect of spray treatment has two: one to be to prevent metal shell 1 surface oxidized further；Two is the requirement (color such as metal shell 1 can be realized by the paint of spraying different colours) meeting user to metal shell 1 sense organ.
The manufacture method of metal shell 1 of the present utility model is different from it is critical only that of the manufacture method of metal shell 1 of the prior art: prior art is to be infused in the through hole that metal shell 1 is offered by plastic cement 5, and this utility model is plastic cement 5 to be injected into bottom be formed in the deep gouge 2 of reserved thin-walled 3.This utility model uses said structure injection plastic cement 5 to be advantageous in that: reserved thin-walled 3 has holding effect to reduce the plastic deformation of plastic cement 5 to the full extent to the plastic cement 5 injected, thus improve the surface quality after plastic forming, and increase the reliability being connected with metal shell 1 simultaneously.
The reliability that plastic cement 5 is connected with metal shell 1 is improved further for the structure by changing deep gouge 2, to prevent plastic cement 5 from separating in subsequent use with metal shell 1, or injecting before plastic cement 5 to deep gouge 2 after offering deep gouge 2, the side along deep gouge 2 processes multiple wedge-shaped slots 4 being evenly arranged.So, plastic cement 5 injects and after plastic forming, plastic cement 5 be positioned at deep gouge 2 main part form card with metallic profiles and set by being positioned at the marginal portion of wedge-shaped slot 4 and be connected, and then the reliability that the plastic cement 5 of increase is connected with metal shell 1.
Wedge-shaped slot 4 can pass through punching press or drilling molding, in a preferred embodiment of the present utility model, and the wedge-shaped slot 4 milling molding by milling cutter 6.
As further preferably, above-mentioned deep gouge 2 is by milling molding.
After injecting plastic cement 5 and making its plastic forming, for preventing reserved thin-walled 3 from continuing the signal of screened shielded antanna, reserved thin-walled 3 abolished by needs, the mode abolishing reserved thin-walled 3 can have multiple, drill bit is utilized to be cut by reserved thin-walled 3 along the edge of reserved thin-walled 3, but the impulsive force of drilling is bigger, the plastic cement 5 easily making plastic forming loosens, in a preferred embodiment of the present utility model, utilize milling cutter 6 to abolish reserved thin-walled 3, specifically make milling cutter 6 travelling with the thickness gradually reducing reserved thin-walled 3 on reserved thin-walled 3 whole plate face.This is abolished mode and is advantageous in that, the impact to plastic cement 5 is less.
The invention also discloses a kind of metal shell 1, this metal shell 1 is will intermediate products integrated with plastic cement 5, metal shell 1 is formed for the deep gouge 2 that plastic cement 5 injects in the position corresponding with notebook computer antenna, deep gouge 2 is not through with metal shell 1 so that the bottom of deep gouge 2 forms one reserves thin-walled 3, and reserved thin-walled 3 is for abolishing after plastic cement 5 plastic forming.
Of the present utility model it is different from it is critical only that for metal shell 1 integrated with plastic cement 5 of the prior art for metal shell 1 integrated with plastic cement 5: prior art is to be infused in the through hole that metal shell 1 is offered by plastic cement 5, and this utility model is plastic cement 5 to be injected into bottom be formed in the deep gouge 2 of reserved thin-walled 3.This utility model uses said structure injection plastic cement 5 to be advantageous in that: reserved thin-walled 3 has holding effect to reduce the plastic deformation of plastic cement 5 to the full extent to the plastic cement 5 injected, thus improve the surface quality after plastic forming, and increase the reliability being connected with metal shell 1 simultaneously.
As further preferably, the side of deep gouge 2 has the wedge-shaped slot 4 being evenly arranged.This wedge-shaped slot 4 is for providing the reliability being connected with plastic cement 5.
As further preferably, reserved thin-walled 3 is 0.2-1.0 with the ratio of the thickness of metal shell 1, and the even thickness 2mm of metal shell 1, metal is reserved thickness and can be chosen between 1mm-0.4mm.
Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model, and protection domain of the present utility model is defined by the claims.This utility model can be made various amendment or equivalent in essence of the present utility model and protection domain by those skilled in the art, and this amendment or equivalent also should be regarded as in protection domain of the present utility model.
