Abstract
The utility model discloses a compound casting of ultra-thin wall light metal alloy cases or frames. The compound casting comprises at least two ultra-thin wall light metal alloy case or frame single bodies, and the single bodies are connected with one another through connecting blocks. Due to the fact that the compound casting comprises at least two ultra-thin wall light metal alloy case or frame single bodies, namely, two or more ultra-thin wall light metal alloy cases or frames are combined to form a thick casting, the hardness of the casting is increased, the defects that the casting is easy to deform out of heat or easy to crack due to the fact that the wall of the single ultra-thin wall light metal alloy case or frame is too thin are overcome, and the cast form percent of pass of the compound casting is improved greatly. Due to the fact that the compound casting is formed through pressure casting, namely, two or more ultra-thin wall light metal alloy cases or frames are cast for one time, the production efficiency of the ultra-thin wall light metal alloy cases or frames is improved.
Description
Technical field
The utility model relates to the metal framework processing technique field, is specifically related to the compound casting of a kind of ultra-thin-wall light metal alloy shell or framework.
Background technology
Shell or the employed material of framework of products such as notebook computer on the market, mobile phone generally have two big classes: a class is light metal alloy, and another kind of is plastics.Because the plastics radiating effect is poor, be eliminated gradually, and the coefficient of heat conduction is the light metal alloys of plastics more than 150 times, becoming the main flow material of product casing such as notebook computer, mobile phone, digital camera or framework rapidly.Light metal alloy has following characteristics: quality is light, density is low, thermal diffusivity is better, hardness and shock resistance dynamics are strong, can satisfy the 3C Product Highgrade integration, lightening, microminiaturized, anti-falling hits electromagnetic shielding and the good requirement of thermal diffusivity, so the advantage of light metal alloy shell or framework is more and more obvious.
At present, the ultra-thin-wall light metal alloy shell of product such as notebook computer, mobile phone or the manufacture method of framework mainly contain following several: a kind of is to adopt fashion of extrusion that section bar is processed into certain thickness earlier, being machined to wall thickness by CNC again is 0.8～1.2mm, the light metal case surface is sprayed with incrustation at last again and handles; Another kind of then be method shaping shell by punching press, carry out mold-in injection (i.e. bonding) or welding again, plastic structural part is attached to the good light metal inner surface of outer cover that is shaped, at last it is carried out surface treatment; Also having a kind of is to adopt the manufacturing of the liquid shape casting method of traditional single products.The complex process of preceding two kinds of processing methods, production a slice light metal notebook computer casing needs 20～30 minutes at least, and its processing cost is high, and the qualification rate of processing is low, generally has only 50～60%.
Adopt the liquid shape casting method of traditional single products to make ultra-thin-wall light metal alloy shell or framework, wall thickness owing to shell when casting is too little, easily produce defectives such as misrun, cold shut in the forming process, and the back that is shaped is because radiating condition is inhomogeneous; the thin-walled place is connected the thermal stress that crossover position produces with other different; be easy to generate thermal deformation or cracking when cooling; often need follow-up correction processing; increase complex process degree; make that the qualification rate of product is lower, and the efficient of cast in one piece is low, cost is high.
The utility model content
The technical problem that the utility model solves provides the compound casting of a kind of ultra-thin-wall light metal alloy shell or framework, this compound casting is more difficult generation thermal deformation or cracking in the cast form process, is conducive to improve manufacturing qualification rate and the production efficiency of ultra-thin-wall light metal alloy shell or framework.
The technical scheme that the utility model adopts is: the compound casting of a kind of ultra-thin-wall light metal alloy shell or framework, it is characterized in that, described compound casting comprises the monomer that is no less than 2 ultra-thin-wall light metal alloy shells or framework, is connected by contiguous block between the monomer.
Described compound casting forms by semi-solid-state shaping die casting.
Described ultra-thin-wall light metal alloy shell or framework are ultra-thin-wall aluminum alloy casing or framework.
Described ultra-thin-wall light metal alloy shell or framework are ultra-thin-wall magnesium alloy case or framework.
The beneficial effects of the utility model are: 1, because the utility model comprises the monomer that is no less than 2 ultra-thin-wall light metal alloy shells or framework, namely be combined into a thicker body of casting by two or more ultra-thin-wall light metal alloy shells or framework, increased the rigidity of product, it is too little because of wall thickness to have overcome single ultra-thin-wall light metal alloy shell or framework, when casting, be easy to generate the shortcoming of thermal deformation or cracking, thereby make the manufacturing qualification rate of ultra-thin-wall light metal alloy shell or framework obtain bigger raising; 2, because the utility model is made by pressure and formed, namely disposablely cast out two or more ultra-thin-wall light metal alloy shells or framework, thereby improved the production efficiency of ultra-thin-wall light metal alloy shell or framework.
