Abstract

The utility model relates to a die -casting formula aluminum alloy cell -phone frame, this cell -phone frame include aluminum alloy frame and the aluminum alloy mounting panel of injection molding inside the aluminum alloy frame that is located the outside, wherein, the inner wall surface of aluminum alloy frame is equipped with several recesses, corresponds ground, the edge shaping of the lateral part of aluminum alloy mounting panel have with the outward flange that the recess corresponds, the both sides of aluminum alloy mounting panel edge still the shaping have the several interval arrangement, along the aluminum alloy mounting panel thickness orientation prominent sand grip that makes progress, the up end salient of sand grip in the up end of aluminum alloy frame, and the sand grip have roll over to turning up with the aluminum alloy frame on end face contaction's kink. The utility model discloses not only process, packaging technology is more simple, has left out loaded down with trivial details aluminum alloy mounting panel lock screw assembly process, is guaranteeing the outside feel of product, protection power in addition and is wear -resistanting, on the basis of durability, is greatly reducing the overall cost of product.

Description

Pressure-casting type aluminium alloy mobile phone framework
Technical field:
The utility model relates to mobile phone parts product technical field, refers in particular to a kind of pressure-casting type aluminium alloy mobile phone framework.
Background technology:
At present, the style of mobile phone framework is varied, but appearance requirement mainly has more the market competitiveness with the mobile phone framework of metal edges frame-type, and more by consumers, one to carry out metal edge frame texture strong, two come more solid, not easy to wear, better to the protected effect of mobile phone.For this reason, the producer, when producing, usually adopts Al alloy block by the aluminum alloy frame of the explained hereafter such as hollow out, cutting integrally formula, then is mounted in aluminum alloy frame with screw by mounting panel, with the various electronic device of connection.Obviously, this mode technique is comparatively complicated, and production material cost is higher, and the assembling of mounting panel is also comparatively loaded down with trivial details.
Utility model content:
The purpose of this utility model is the weak point overcoming existing equipment, provides a kind of pressure-casting type aluminium alloy mobile phone framework.
The technical solution adopted in the utility model is: a kind of pressure-casting type aluminium alloy mobile phone framework, this mobile phone framework comprises the aluminum alloy frame and the aluminium alloy mounting panel of die cast in aluminum alloy frame inside that are positioned at outside, wherein, the inner wall surface of described aluminum alloy frame is provided with several grooves, accordingly, the side margins of described aluminium alloy mounting panel forms the outward flange corresponding with described groove; Also form in the both sides of the edge of aluminium alloy mounting panel several spaced, along aluminium alloy mounting panel thickness direction raised line upwardly, the upper surface of described raised line protrudes from the upper surface of described aluminum alloy frame, and raised line has the kink outwards turning down and contact with aluminum alloy frame upper surface.
The groove of the inwall of described aluminum alloy frame is discontinuous, point two rows are arranged in parallel.
The utility model is not only processed, packaging technology is more simple, eliminates loaded down with trivial details aluminium alloy mounting panel lock screw assembling process, and on the basis ensureing the outside texture of product, protection and wear-resistant, durability, significantly reduces the holistic cost of product.
Accompanying drawing illustrates:
Fig. 1 is the decomposition texture schematic diagram of the utility model mobile phone framework;
Fig. 2 is the overall structure schematic diagram of the utility model mobile phone framework;
Fig. 3 is the partial enlarged drawing at A place in Fig. 1.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1-Figure 3, described in the utility model is a kind of pressure-casting type aluminium alloy mobile phone framework, this mobile phone framework comprises the aluminum alloy frame 1 and the aluminium alloy mounting panel 2 of die cast in aluminum alloy frame 1 inside that are positioned at outside, wherein, the inner wall surface of described aluminum alloy frame 1 is provided with several grooves 11, accordingly, the side margins of described aluminium alloy mounting panel 2 forms the outward flange 21 corresponding with described groove 11; Also form in the both sides of the edge of aluminium alloy mounting panel 2 several spaced, along aluminium alloy mounting panel 2 thickness direction raised line 22 upwardly, the upper surface of described raised line 22 protrudes from the upper surface of described aluminum alloy frame 1, and raised line 22 has the kink 221 outwards turning down and contact with aluminum alloy frame 1 upper surface.
During making, first make aluminum alloy frame 1, and in aluminum alloy frame 1 shaping groove 11, then aluminum alloy frame 1 is put into die casting, liquid aluminium alloy liquation is expelled in die casting, in press casting procedure, mold aluminium alloy mounting panel 2, the surface of aluminium alloy mounting panel 2 forms the male and fomale(M&F) of applicable installing electronic elements, and its edge is then solidified by the molten aluminium alloy be injected in the groove 11 flowing into aluminum alloy frame 1 and forms outward flange 21, thus forms positioning combination; Simultaneously, also mold the raised line 22 with outward flanging, raised line 22 place is as exhaust outlet in mould in injection molten aluminium alloy process on the one hand, guarantee the mobility of molten aluminium alloy, make aluminium alloy mounting panel 2 evenly shaping, on the other hand, raised line 22 also increases aluminium alloy mounting panel 2 and the bonded area of aluminum alloy frame 1 as being conducive to, and increases combination stability; By the groove 11 of aluminum alloy frame 1 inwall and the outward flange 21 of aluminium alloy mounting panel 2 sidepiece cooperatively interact and screens etc. between the kink 221 of raised line 22 and aluminum alloy frame 1 upper surface realizes the location of aluminum alloy frame 1 and aluminium alloy mounting panel 2, the two process combined completes while the die cast of aluminium alloy mounting panel 2, without the need to extra assembling process, therefore production efficiency is high; In addition; that aluminum alloy frame 1 can adopt comparative good-quality, that cost is higher aluminum alloy materials is by making such as cutting, hollow outs; product outside can be made to have good metal-like and the protective effect to inner member; and the aluminium alloy mounting panel 2 of inside can adopt relatively inexpensive, to be applicable to die casting aluminum alloy materials; significantly can reduce the cost of manufacture of whole product like this, improve product competitiveness.
The groove 11 of the inwall of described aluminum alloy frame 1 is discontinuous, point two rows are arranged in parallel, and makes its locating effect better, assembles more stable.
The utility model is not only processed, packaging technology is more simple, eliminates loaded down with trivial details aluminium alloy mounting panel lock screw assembling process, and on the basis ensureing the outside texture of product, protection and wear-resistant, durability, significantly reduces the holistic cost of product.
