Along with the development of smithcraft technology and human consumer are to the demand of innovative product, need badly and design and develop the trendy product that production cost is low, intensity is high, to satisfy the demands of consumers.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of metallic mobile phone housing.
The purpose of this utility model is achieved through the following technical solutions: a kind of metallic mobile phone housing, comprise left metal edge frame, right metal edge frame, and connect the upper injection moulding plastic frame of left metal edge frame and right metal edge frame, injection moulding plastic backboard and under mould plastic frame, upper injection moulding plastic frame, injection moulding plastic backboard and under mould the integral piece that plastic frame is injection moulding, the face, right side of left metal edge frame is provided with for connecting upper injection moulding plastic frame, injection moulding plastic backboard and under mould the injecting hole of plastic frame, the face, left side of right metal edge frame is provided with for connecting upper injection moulding plastic frame, injection moulding plastic backboard and under mould the injecting hole of plastic frame, upper injection moulding plastic frame, injection moulding plastic backboard and under mould plastic frame two ends be all filled in the injecting hole of respective side by injection moulding machine, namely injection moulding plastic frame is gone up, injection moulding plastic backboard and under mould plastic frame left end be filled in by injection moulding machine in the injecting hole of left metal edge frame, upper injection moulding plastic frame, injection moulding plastic backboard and under mould plastic frame right-hand member be filled in the injecting hole of right metal edge frame by injection moulding machine.
The rear side of described injection moulding plastic backboard is coated with electromagnetism layer of fibers, silicate thermal baffle layer, small hollow sphere powder bed and ceramic fiberboard successively along direction from front to back. Described small hollow sphere powder bed is that the silicon oxide hollow powder that particle diameter is less than 100 ��m is coated on silicate thermal baffle layer surface and is formed.
Described electromagnetism layer of fibers is the clathrum with multiple parallelogram that many function solenoid fibers are interlaced with each other formed.
Left metal edge frame and right metal edge frame are placed in plastic injection mold, the injecting hole of left metal edge frame and right metal edge frame all connects the plastic cement runner of injection mold, adopt injection moulding machine in plastic injection mold, inject melt plastic cement material, through pressurize cool after obtain upper injection moulding plastic frame, injection moulding plastic backboard and under mould plastic frame.
The utility model has the following advantages:
Injection moulding plastic frame on the utility model, injection moulding plastic backboard and under mould plastic frame and be provided with the injecting hole for connecting injection moulding plastic portion, obtain handset shell entirety by injection moulding; Good product consistency, good rate is improved, and can improve working (machining) efficiency, and parts bonding force is good, adopts integrative-structure processing compared to existing middle frame, greatly reduces cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of right metal edge frame.
In figure, the left metal edge frame of 1-, the right metal edge frame of 2-, the upper injection moulding plastic frame of 3-, 4-injection moulding plastic backboard, moulds plastic frame under 5-, 6-injecting hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of metallic mobile phone housing, comprise left metal edge frame 1, right metal edge frame 2, and connect the upper injection moulding plastic frame 3 of left metal edge frame 1 with right metal edge frame 2, injection moulding plastic backboard 4 and under mould plastic frame 5, upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould the integral piece that plastic frame 5 is injection moulding, the face, right side of left metal edge frame 1 is provided with for connecting upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould the injecting hole 6 of plastic frame 5, the face, left side of right metal edge frame 2 is provided with for connecting upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould the injecting hole 6 of plastic frame 5, upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould plastic frame 5 two ends be all filled in the injecting hole 6 of respective side by injection moulding machine, upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould plastic frame 5 left end be filled in by injection moulding machine in the injecting hole 6 of left metal edge frame 1, upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould plastic frame 5 right-hand member be filled in the injecting hole 6 of right metal edge frame 2 by injection moulding machine.
The rear side of described injection moulding plastic backboard 4 is coated with electromagnetism layer of fibers, silicate thermal baffle layer, small hollow sphere powder bed and ceramic fiberboard successively along direction from front to back. Described small hollow sphere powder bed is that the silicon oxide hollow powder that particle diameter is less than 100 ��m is coated on silicate thermal baffle layer surface and is formed.
Described electromagnetism layer of fibers is the clathrum with multiple parallelogram that many function solenoid fibers are interlaced with each other formed.
Left metal edge frame 1 and right metal edge frame 2 are placed in plastic injection mold, the injecting hole 6 of left metal edge frame 1 and right metal edge frame 2 all connects the plastic cement runner of injection mold, adopt injection moulding machine in plastic injection mold, inject melt plastic cement material, through pressurize cool after obtain upper injection moulding plastic frame 3, injection moulding plastic backboard 4 and under mould plastic frame 5.
Injection moulding plastic frame 3 on the utility model, injection moulding plastic backboard 4 and under mould plastic frame 5 and be provided with the injecting hole 6 for connecting injection moulding plastic portion, obtain handset shell entirety by injection moulding; Good product consistency, good rate is improved, and can improve working (machining) efficiency, and parts bonding force is good, adopts integrative-structure processing compared to existing middle frame, greatly reduces cost.
