Description
Technical field
The utility model belongs to the technical field of notebook annex, is specifically related to a kind of notebook fan of injection molding
Blade.
Background technology
The quality of radiating fan for computer quality is not only in that radiating effect, quality and service life, and another
Main factor is the size of decibel when radiator fan uses, and is compared by two 14 inches of notebooks to same brand
Compared with the manufacture production base is different, and the performance of this two 14 inches of notebooks is then uneven, a from produced in USA
Only 48.7 decibels, another money from domestic product then be up to 66.3 decibels, it is seen that we when choosing notebook, should not light see
Outward appearance and configuration, preferably move close to again and heard its fan noise and control whether ideal, in the case of manufacturing line identical,
Difference mostlys come from injection molding blade fan piece respectively for it, produces with blade fan die machining accuracy and directly contacts.
Most of fan blade of existing injection molding is used in sharf and blade combining structure, passes through blade shape
Upper change makes it meet the requirement of active computer work, and also some uses reinforcing rib structure in blade tip, although the structure
The intensity of blade can be increased, in the case where meeting rotating speed, increase air quantity and radiating effect, but be increased centrifugal force, increased
Add the friction between sharf inwall and motor shaft, cause noise bigger.
The content of the invention
In view of this, the purpose of this utility model is the notebook fan blade for providing a kind of injection molding, the one kind
The notebook fan blade of injection molding is arranged in the middle part of fan blade, the reinforcement by being provided with reinforcement using reinforcement
Muscle side wall is arranged to arcuate structure, and the structure can not only improve blade strength, and conveniently form air-flow, improves fan effect
Rate, and facilitate the lower reinforcement bottom of thimble effect, it is convenient by formed blades from mold ejection.
In order to achieve the above object, the notebook fan blade of a kind of injection molding of the utility model, including sharf and
It is uniformly arranged and is wound on fan blade horizontal direction in the axial fan blade of blade, in addition to reinforcement, the reinforcing rib ring
Medium position and fan blade is connected, centre bore, the reinforcement bottom and wind are provided with the sharf axial direction
Fan leaf vertical direction bottom connects, and top is arranged on fan blade vertical direction medium position, and upper width from bottom to
Top to air outlet side becomes larger, and the reinforcement upper portion side wall is provided for the arcwall face of wind-guiding.
Further, the reinforcement bottom is arranged on fan blade and extends fan blade bottom, and it extends height and set
It is set to 0.5~2mm.
Further, it is arranged on the opening position of fan blade 1/2~2/3 at the top of the reinforcement.
Further, the tolerance grade of the centre bore is arranged to 0.002mm.
The beneficial effects of the utility model are：
A kind of notebook fan blade of injection molding of the utility model is set by being provided with reinforcement using reinforcement
In the middle part of fan blade, the reinforcement side wall is arranged to arcuate structure, and the structure can not only improve blade strength, and conveniently
Air-flow is formed, improves fan efficiency, and facilitates the lower reinforcement bottom of thimble effect, it is convenient to push up formed blades from mould
Go out.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the notebook fan blade of injection molding of the utility model；
Fig. 2 is the partial enlarged drawing of reinforcement in Fig. 1.
Reference：1- sharfs；2- fan blade；3- reinforcements；4- centre bores；The upper moulds of 5-；Mould under 6-.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
It is a kind of structural representation of the notebook fan blade of injection molding of the utility model as shown in Figure 1；Such as Fig. 2 institutes
It is shown as the partial enlarged drawing of reinforcement in Fig. 1；A kind of notebook fan blade of injection molding of the utility model, including sharf
1 and the fan blade 2 that is uniformly arranged around sharf 1, in addition to reinforcement 3, the reinforcement 3 be looped around fan blade 2
Horizontal direction medium position and fan blade 2 is connected, centre bore 4, the reinforcement are provided with the axial direction of sharf 1
The bottom of muscle 3 is connected with fan blade vertical direction bottom 2, and top is arranged on fan blade vertical direction medium position, and top
Width becomes larger from bottom to top to air outlet side, and the upper portion side wall of reinforcement 3 is provided for the arcwall face of wind-guiding.
In injection molding, the bottom of reinforcement 3 is molded in the groove of mould 5 the present embodiment, to reinforcement at the top of fan blade
For drape forming in the lower groove of mould 6, the bottom both sides of reinforcement 3 are arranged to relatively parallel plane, convenient to strengthen between the top of muscle 3
Muscle 3 and blade come off from upper mould, and thimble acts on the top of reinforcement 3, is conveniently ejecting formed blades from mold ejection
Cheng Zhong, fan blade will not be damaged, improve fan blade quality.
The present embodiment is arranged on the middle part of fan blade 2 using reinforcement 3, and the reinforcement side wall is arranged to arcuate structure, should
Structure can not only improve blade strength, and conveniently form air-flow, improve fan efficiency, and facilitate thimble effect is lower to strengthen
Muscle bottom, it is convenient by formed blades from mold ejection.
Further, the preferable bottom of reinforcement 3 is arranged on fan blade and extends fan blade bottom, and it extends
0.5~2mm is highly arranged to, the structure is advantageous to improve the intensity of fan blade, improves wind-guiding efficiency.
Further, the preferable top of reinforcement 3 is arranged on the opening position of fan blade 1/2~2/3, and the structure is being molded
During shaping, reinforcement 3 is molded in mould groove, recessed in lower mould to shaping structures between the top of reinforcement 3 at the top of fan blade
In groove, facilitate the lower reinforcement bottom of thimble effect, it is convenient by formed blades from mold ejection.
Further, the tolerance grade of the preferable centre bore 4 is arranged to 0.002mm, and the structure advantageously reduces fan
Friction between blade and motor reel, reduce the decibel of fan blade.
Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model has been described in detail by above preferred embodiment for pipe, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The scope of restriction.
