Embodiment
Shown in Fig. 1, Fig. 2, it is related to a kind of LED lamp cover, its concrete structure includes：The lamp shade body 11 of long tubular, lampshade sheet
On the inner wall of body 11 by two lateral middle parts, by it is close to thin formed with zigzag light refractive structures 15；Shape on the outer wall of lamp shade body 11
Into there is the wavy light refractive structures 12 that are made of a plurality of semicircle fin.In this way, when the light in lampshade is spread to both sides, energy
Enough realize batswing tab light distribution, and the wavy light refractive structures 12 that outer wall is formed, emergent light spot can be made more uniform, no blackening.
Using zigzag light refractive structures, it can allow the light into side that refraction or full transmitting occurs, change radiation direction；When sawtooth by
Two lateral middle parts, by it is close formed to what is dredged after, lamp luminescence angle is more than 180 ° so that light extraction covering lamp body periphery, realization
The effect of three-dimensional.Furthermore it is also possible to dust cover 13 made of plastic tab are provided at both ends with lamp shade body 11, thus
It can ensure the cleaning in LED lamp cover, reduce pollution.
The preferable choice of technology is that the zigzag light refractive structures 15 and wavy light refractive structures 12 in the present invention can all use
Makrolon or polymethyl methacrylate materials are made.
In addition, for cause light that LED light is sent can make after being projected by LED lamp cover emergent light spot distribution more uniformly,
Exquisiteness, can be designed as 0.6mm, its bottom by the tooth pitch of the top sawtooth of the above-mentioned sawtooth zigzag light refractive structures 15 in the present invention
The tooth pitch of sawtooth is designed as 1.2mm.More preferred technical solution is that the spacing of top sawtooth and bottom sawtooth is arranged on 5-
Between 8mm；More preferable refraction effect can so be reached.
Shown in Fig. 3 to Fig. 4, for make the present invention LED lamp cover extrusion molding apparatus, its mainly include rack 1, according to
The secondary servomotor 2 being installed in rack 1, gear reducer 3 and screw device 6, screw device 6 are encapsulated in the collecting in machine barrel 7
In groove 5；Machine barrel 7 includes feeding section and melt zone, and the top of feeding section is equipped with feed inlet 4, and the port of export 9 of melt zone connects tangible
Into the mouth mold 8 of LED lamp cover.
Wherein, the concrete structure of the mouth mold 8 further includes the cavity 81 with shaping tubulose lampshade, and matches with cavity 81
The module 82 of conjunction；The feed side of cavity 81 passes through the outlet of first material runner 85 and second material runner 87 and melt zone respectively
The connection of end 9；A plurality of semicircular groove structure 83 is also formed with the side wall of cavity 81；On the outer wall of module 82 by both sides into
Portion, by it is close to dredge formed zigzag bulge-structure 84.
The preferable choice of technology is to be designed to be interconnected by first material runner 85 and second material runner 87, and the
The internal diameter of feed inlet to the discharge port of one material flow path 85 and second material runner 87 tapers into, and is so squeezed easy to liquid material
Go out shaping.In addition, the outside of the module 82 is additionally provided with sealing baffle 86 matched with the external port of mouth mold 8, and seal gear
Draw ring 88 is additionally provided with plate 86.
The operation principle of the equipment is：Servomotor 2 drives gear reducer 3 to drive screw device 6 to work, by plastics from charging
Mouth 4 is poured into machine barrel 7, and at this time, plastics travel forward under the progradation of screw device 5.In the process, material constantly quilt
It is fed forward and is compacted, plastics is gradually reaching the temperature of viscous state, and start to melt due to the effect of frictional heat in melt zone
Change, last level pressure, constant temperature, the mouth mold 8 of the quantitative port of export from melt zone carry out extrusion molding, due to having in the mouth mold 8
The cavity 81 of tubulose lampshade, and module matched with cavity 81 82 are molded, a plurality of half is also formed with the side wall of cavity 81
Circular groove structure 83；On the outer wall of module 82 zigzag bulge-structure 84 has been formed to what is dredged by both sides to middle part, by close；
As it can be seen that the internal structure of above-mentioned mouth mold 8 can have the LED lamp cover of structure of the present invention with straight forming.Therefore, when the viscosity flow of thawing
After state plastics are pressed into cavity 81 by first material runner 85 and second material runner 87 respectively, then through supercooling, fixed
Type, can finally be pulled out the module 82 with draw ring 88 by dragger, finally obtain the LED lamp cover main body knot of the present invention
Structure, subsequently can carry out corresponding processing and fabricating according to being actually needed.
It should be noted that herein, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
