Description
Technical field
The present invention relates to a kind of mould, especially the mould of special-shaped high-power LED metal electronic circuit board (PCB).
Background technology
Traditional electronic circuit board generally is plating one deck copper film on the substrate of being made by epoxy resin, and its cost is low, and technology is simple, generally is used for the less demanding electronic product of common heat radiation.Along with the technology of electronic product is maked rapid progress, LED is because its optical efficiency height, energy-saving and environmental protection, obtains more and more widely application at each lighting field.As in automobile lamp, LED is long because of its luminous efficiency height, life-span, is applied to auto lamp and is more and more paid attention to by each auto vendor.But will be used as automotive lighting, this LED need use and powerfully just can meet the automotive lighting requirement.So traditional film-type electronic circuit board just is not suitable for installing great power LED, because of its radiating effect relatively poor, the heat that great power LED sends can not distribute preferably, will reduce greatly the result of use and the service life of automobile lamp, even causes security incident.Thereby the automobile-used LED electronic circuit board all adopts metallic plate at present, is called PCB in the industry.Present PCB is flat, and its processing technology is simple, only needs promptly to can be made into by punch die of line construction, and the precision of the installing hole of LED also can guarantee after the punching out.But many automobile lamps are arranged as adopting LED, its electronic circuit board 1 is abnormally-structured (as shown in Figure 1), its irregular, big drop, not contour, trapezoidal step structure, complex structure, adopt traditional impact forming method, because metal can extend (percentage elongation of copper is higher) in metal, then after punching out, be difficult to guarantee the precision of locating hole 2, LED installing hole 3, influence the installation of LED in the postorder operation.So just influenced the popularization and application of LED in automobile lamp greatly.
Summary of the invention
The objective of the invention is at afore-mentioned, a kind of mould that is widely used in the special-shaped high-power LED metal electronic circuit board of automobile lamp is provided.
The technical scheme that realizes above-mentioned purpose is as follows:
Special-shaped high-power LED metal electronic circuit board forming die, has a base plate, its both sides, top are provided with the mould support plate, mould support plate inboard is provided with guiding die plate, the base plate of guiding die plate inboard is provided with the movable matrix that has some special-shaped dies, one camshaft passes and is coupling on two side mold support plates, be connected with cam set on the camshaft of mould support plate inboard, cam set is made up of the some cams that are coupling vertically successively on camshaft, the center of gravity line of each cam of cam set is all not parallel at synchronization, the below of corresponding each cam is provided with a slip core rod that can be subjected to this cam extruding on guiding die plate, the lower end of each core rod that slides for the corresponding special-shaped punch of the special-shaped die over against the position of the movable matrix of its below.
The stepped arrangement of special-shaped die on the movable matrix.The main shape of special-shaped PCB of using LED on the automobile lamp is stepped.
Described camshaft is by the power wheel transmission.A lot of in the power resources prior art of power wheel, adopted cylinder comparatively suitable in actual production process drives.
Advantage of the present invention has provided a kind of special-shaped metal electron circuit board that is used for great power LED, provides guarantee for great power LED uses in the automotive lighting light fixture widely.And the advantage of comparing with traditional lighting because of well-known LED illumination, the present invention has higher society and economy benefit.

The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
Special-shaped high-power LED metal electronic circuit board forming die, has a base plate 4, its both sides, top are provided with mould support plate 5, mould support plate 5 inboards are provided with guiding die plate 7, the base plate 4 of guiding die plate 7 inboards is provided with the movable matrix 6 that has 11 special-shaped dies 61, one camshaft 8 by power wheel 81 transmissions passes and is coupling on two side mold support plates 5, be connected with cam set 9 on the camshaft 8 of mould support plate 5 inboards, cam set 9 is made up of 11 cams 91 that are coupling vertically successively on camshaft 8, the center of gravity line of each cam 91 of cam set 9 is all not parallel at synchronization, the below of corresponding each cam 91 is provided with a slip core rod 10 that can be subjected to these cam 91 extruding on guiding die plate 7, the lower end of each core rod 10 that slides is the special-shaped punch 101 corresponding with the special-shaped die 61 over against the position of the movable matrix 6 of its below.
Special-shaped die 61 stepped arrangements on the movable matrix 6.
Below sketch operation principle: PCB (is treated punching out, plane) be as the criterion with locating hole 2 and put into movable matrix, power wheel drives camshaft and rotates, camshaft drives cam set and rotates, extruding slip core rod when the nose of a certain cam goes on the slip core rod of its correspondence, the special-shaped punch punching press of lower end that makes the slip core rod is to the special-shaped die of its correspondence, and PCB that then should the place is by punch forming.
For guaranteeing that PCB does not influence precision because of the pressurized extension makes locating hole, LED installing hole also be out of shape displacement thereupon, in cam set in the layout of adjacent cams according to following rule: when guaranteeing to suppress the back one-level ladder of PCB, the not loose pressure of slip core rod on the previous stage ladder, have only when the slip core rod is pressed onto back one-level ladder again, slip core rod on the previous stage ladder could be pressed by pine, so circulation.
