Abstract
The utility model discloses section injection moldings in a kind of axial-flow fan to exempt from abridged edition body in stereotyped structure, including fan blade, and abridged edition body includes the blade on middle section end plate and middle section end plate in the fan blade, and the blade tip is provided with cyclic annular muscle at outer body towards saving in fan blade；Section structure in fan blade after improvement, cyclic annular muscle reinforces the structural strength of axial-flow fan, improve blade Hot Deformation Performance simultaneously, especially cyclic annular muscle, which is located in fan blade, saves fan blade end position at outer body, can not influence to demould in injection phase while play and can play a supporting role.
Description
Technical field
The utility model relates to axial-flow fan technical field, stereotyped structure is exempted from section injection molding in especially a kind of axial-flow fan.
Background technique
The axial-flow fan of air-conditioning indoor hanging unit is welded by saving in a section fan.Section structure form is in fan
The middle section end plate connection fan blade of one end, integrated injection molding.In actually injection molding production, section is infused from mold cavity in fan
The uncolled stage is moulded out, since aspect ratio is big, thickness is thin, only there is end plate support in one end, and the other end is freely without constraint
State is easy outwardly or inwardly to deform.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides section injection molding in a kind of axial-flow fan and exempts from stereotyped structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Abridged edition body in stereotyped structure, including fan blade is exempted from section injection molding in a kind of axial-flow fan, and abridged edition body includes in the fan blade
Blade on middle section end plate and middle section end plate, the blade tip are provided with cyclic annular muscle at outer body towards saving in fan blade.
As a preference, the vane tip face and cyclic annular muscle end face.
As a preference, convex block is provided at the vane tip, the ring-type muscle end face is than convex block upper end position
It is low.
The beneficial effects of the utility model are: section structure, the structure that cyclic annular muscle reinforces axial-flow fan are strong in fan blade after improvement
Degree, while improving blade Hot Deformation Performance, especially cyclic annular muscle, which is located in fan blade, saves fan blade end position at outer body, can
It does not influence to demould in injection phase while playing and can play a supporting role.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the partial enlarged view of the utility model；
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The utility model is further elaborated.For the thorough explanation present invention, some spies can be related in following description
Determine details.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses this
These of place describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, Fig. 2, abridged edition body in stereotyped structure, including fan blade, the fan blade are exempted from section injection molding in a kind of axial-flow fan
Middle abridged edition body includes the blade 2 on middle section end plate 1 and middle section end plate 1, and 2 end of blade is saved at outer body towards in fan blade
It is provided with cyclic annular muscle 3.It can play a supporting role towards the cyclic annular muscle 3 in outside in injection phase, to prevent blade 2 in cooling
It deforms in the process, ring-type muscle 3 is corresponding with the middle section end plate 1 of abridged edition body in another fan blade when middle section bottle connects.Additionally due to
Cyclic annular muscle 3 is to be located at 2 end of blade to save at outer body towards in fan blade, without on 2 end end face of blade, in axial-flow fan
Demoulding is not influenced in middle section injection moulding process can save shaper shaping process simultaneously, the saving production time, human cost and
Fixture cost, increases economic efficiency.
As an implementation, 3 end face of 2 tip surface of blade and cyclic annular muscle, convenient for precisely processing.
As another embodiment, convex block 4 is provided at 2 tip of blade, 3 end face of the ring-type muscle is than convex block 4
Upper end position is low, and convex block 4 is corresponding with the 1 grafting position of middle section end plate of abridged edition body in another fan blade, convenient for assembling.
According to above-mentioned principle, the utility model can also be made appropriate changes and modifications to the above embodiments.Therefore,
The utility model is not limited to specific embodiment disclosed and described above, to some modifications and changes of the utility model
It should also be as falling into the protection scope of the claims of the present utility model.
