Description
Technical field
The present invention relates to a kind of LED, the radiating piece and processing method of particularly a kind of LED.
Background technology
LEDbulb lamp radiating piece of the prior art includes metalwork and working of plastics, and metalwork is typically thicker gold
Category material is integrally formed by rolling tension-thining, does not have opening, the processing of metalwork on the face that metalwork is contacted with working of plastics
Difficulty is big, and processing efficiency and yield rate are low, cause high cost.There is two ways at present for the combination of metalwork and working of plastics,
A kind of is that the metalwork without open slot that will be processed first is put into injection mold and then injection, due to metalwork during injection
Harder, in injection, metalwork easily pierces through working of plastics, makes metalwork partial denudation outside, easily causes defective products.In addition
A kind of mode is injection molded plastic parts first, and the metalwork that then will be processed is put into working of plastics, this mode processing efficiency compared with
It is low, and metalwork can not possibly be fully mated with the surface of working of plastics, and heat transfer efficiency is not high.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of low production cost, manufacture efficiency is high, and heat transfer efficiency is high
LED radiating piece and its processing method.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of LED radiating piece, including metalwork and working of plastics, the metalwork by sheet metal brake forming, on metalwork
Axially there is an open slot along moulding inner chamber, there is injected plastics material to fill in the open slot of the metalwork.
The open slot is linear on metalwork or shaped form.
The injected plastics material filled in the metalwork open slot spills into metalwork inner surface.
There is no gap between the metalwork outer surface and the injected plastics material of working of plastics, combine closely.
The open slot axially penetrates through metalwork along moulding inner chamber.
The lower end of the metalwork is provided with the flange towards working of plastics side.
Flange of the open slot through metalwork.
The edge of the flange sets jagged, and the working of plastics is provided with the positioning convex in the breach, institute
State surface of the positioning convex higher than the flange.
The flange is provided with through hole, and the working of plastics has the pilot hole alignd with the through hole.
The processing method of above-mentioned LED radiating piece is that sheet metal bending is made to sense along into moulding inner chamber axial direction first
With a metalwork for open slot, metalwork is put into injection mold, is subsequently adding injected plastics material and forms working of plastics, in note
Injected plastics material is filled with while modeling in the open slot.
The beneficial effects of the invention are as follows：Metalwork of the invention is by the way of sheet metal brake forming, it is possible to use
Thinner sheet metal is shaped than calendering mode, the utilization rate of metal material improves more than 8% than current calendering mode, the gold for using
Category material thickness reduces 8% than calendering mode, and corresponding production cost is substantially reduced, and processing efficiency is greatly improved, due to metalwork
With injected plastics material in in-mold molding, contact of the sheet metal with working of plastics is even closer, therebetween without gap, with reference to tight
Close, heat transfer efficiency is higher.Further, since there is open slot on metalwork, metalwork is set to form an elastomer, metal during injection
Part can have unnecessary injected plastics material to be oozed out from fluting with self-adaptative adjustment mould and the position of injected plastics material, and yield rate compares mesh
The preceding product without open slot improves more than 5%.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is exploded view of the invention；
Fig. 2 is upward view of the invention.
Specific embodiment
Reference picture 1, Fig. 2, a kind of LED radiating piece, including metalwork 1 and working of plastics 2, the metalwork 1 are thick by 0.5mm
Sheet metal brake forming, on the periphery of the metalwork 1 along moulding inner chamber axially have a linear for running through
Open slot 3, the cavity that moulding inner chamber surrounds for the inner surface of metalwork 1 in LED radiating piece, it is axially two from top to bottom
Direction between opening, through the periphery of metalwork, the gap of the opening of open slot 3 is filling part 4 to open slot 3.Metalwork 1
Material can be the good metals of heat conductivility such as aluminium or copper, and the present embodiment selection aluminium flake is processed into metalwork 1.The open slot 3
Or arc line shaped.
The lower end of metalwork 1 is provided with flange 5, and flange 5 can make LED lamp panel big with the area of heat sink contact, be conducive to
Radiating and installation are fixed.Flange 5 is provided with through hole 8, and working of plastics 2 is provided with the pilot hole 9 alignd with the through hole 8, pilot hole 9
Interior loading screw, LED lamp panel is fixed in radiating piece.
The edge of flange 5 sets jagged 6, and the working of plastics 2 is provided with the positioning convex 7 in breach 6, convex
7 surfaces for being higher than the flange 5 are played, the edge of LED lamp panel is provided with locating notch, after assembling, the insertion positioning of positioning convex 7
In breach, the fixing hole in LED lamp panel is set to be alignd naturally with pilot hole 9.
The processing method of above-mentioned LED radiating piece is that sheet metal bending is fabricated on periphery along moulding first
Inner chamber axially has a metalwork 1 for the linear open slot 3 for running through, and then metalwork 1 is put into injection mold, will note
Moulding material injection mold injection forms working of plastics 2.The injected plastics material for having certain fluidity during injection is filled into open slot 3,
If after the filling part of injected plastics material filling open slot 3, injected plastics material can overflow into the inner surface of metalwork 1.Convex
7 are played, pilot hole 9 is formed in injection.
By the way of sheet metal brake forming, the utilization rate of metal material is improved metalwork 1 than current calendering mode
More than 8%, meanwhile, the metal material thickness for using reduces 8% than calendering mode, and corresponding production cost is substantially reduced, processing effect
Rate is greatly improved, very close to each other therebetween due to metal and injected plastics material injection molding in a mold simultaneously, is combined closely,
Heat transfer efficiency is higher.
The metalwork without open slot that existing processing mode will be processed first is put into injection mold and then injection,
Do not possess open slot, easily cause defective products；Another mode is injection molded plastic parts, the metalwork that then will be processed first
Be put into working of plastics, though after adhesive connection, the radiating that this mode is processed are added between the metalwork that is put into and moulding
Part yield rate is low, and high cost, processing efficiency is relatively low, and heat transfer efficiency is not high.
Technical scheme makes metalwork form an elastomer due to there is open slot on metalwork, gold during injection
Category part can have unnecessary injected plastics material to be filled into open slot, yield rate with self-adaptative adjustment mould and the position of injected plastics material
More than 5% is improved than the product currently without open slot.
