Abstract
The utility model discloses the injection molding wind framves of fan assembly, including use the molding plastics frame body of a Shooting Technique, and the centre of plastics frame body is equipped with fan mounting holes, it is characterised in that：Elastomer is arranged in the surrounding of plastics frame body, and elastomer is molded on plastics frame body using two-shot process；The back side of fan mounting holes is equipped in lower half blocks cover, the outer rim setting peripheral board for blocking cover is trapped among the protrusion edge of fan mounting holes, the outer rim for blocking cover also sets up cutting, the bottom of cutting is equipped with front and back coupler body, the plastics frame body back side and cutting corresponding position are equipped with slot, and the lower half in slot slot has wider groove width in front-rear direction to adapt to coupler body before and after elasticity is opened.The utility model can solve the problems, such as that wind frame is bonded when automobile radiator framework surface is installed with the reliable of radiator frame surface, improve heat dissipation effect, and damping effect is played, while preventing foreign matter from entering fan mounting holes from lower part equipped with cover is blocked, the replacement for blocking cover is easy for installation.
Description
Technical field
The utility model relates to a kind of automobile fan assemblies, and in particular to a kind of injection molding wind frame of fan assembly.
Background technique
Cooling device for automobile engine with water it is cooling based on, with the circulating water in cylinder water channel, heated in water channel
Water introduce radiator, by being again returned in water channel after air cooling.In order to improve the cooling capacity of radiator, need radiating
Automobile fan forced ventilation is installed behind device.Automobile fan be fixedly mounted on radiator frame by wind frame, currently,
The wind frame and radiator frame of automobile fan are all made of hard material, and the two, which is fitted together, belongs to hard contact, and due to
How much contraction of the wind frame in injection molding process, have a deformation, therefore wind frame and radiator frame surface are bonded with regard to bad,
It is easy to cause when fan work and laterally leaks out, influence heat dissipation effect, while connection vibration between the two also can be larger, is easy
It now loosens and influences service life.In addition, some larger foreign matters of the bodily form are made by the air draught of fan when automobile fan works
With, it is easy to enter fan mounting holes from the lower half of fan mounting holes, influence fan safe operation.
Summary of the invention
In view of the deficiencies in the prior art, the utility model, which provides one kind, can solve wind frame on automobile radiator framework surface
It is bonded problem with the reliable of radiator frame surface when installation, improves heat dissipation effect, and play damping effect, while being equipped with and blocking
The fan assembly that cover prevents foreign matter from entering fan mounting holes from lower part is molded wind frame.
The utility model adopts the following technical scheme that complete：
The injection molding wind frame of fan assembly, including use the molding plastics frame body of a Shooting Technique, the centre of plastics frame body
Equipped with fan mounting holes, it is characterised in that：The surrounding of plastics frame body is arranged elastomer, elastomer using two-shot process at
Type is on plastics frame body.
The surrounding of plastics frame body be equipped with injecting hole by quadric injection mould elastomer partial stowage wherein.
The back side of fan mounting holes is equipped in lower half blocks cover, and the outer rim setting peripheral board for blocking cover is trapped among fan installation
The protrusion edge in hole, the outer rim for blocking cover also set up cutting, and the bottom of cutting is equipped with front and back coupler body, and elasticity is set between the coupler body of front and back
It sets, the plastics frame body back side and cutting corresponding position are equipped with slot, and the lower half in slot slot has wider slot in front-rear direction
Width is to adapt to the front and back coupler body that elasticity is opened, slot and plastics frame body integrated injection molding.
After adopting the above technical scheme, the surrounding two-shot process of wind frame plastics frame body forms elastomer, installation
When be in contact by elastomer with radiator frame surface, so, not only solve wind frame on automobile radiator framework surface
It is bonded problem with the reliable of radiator frame surface when installation, guarantee is not leaked out laterally, improves heat dissipation effect, and play good
Damping effect.Meanwhile the back side of fan mounting holes is equipped in lower half and blocks cover, can prevent foreign matter from entering fan mounting holes,
Ensure that fan is safely operated.
Detailed description of the invention
The utility model has following attached drawing：
Fig. 1 is the structural schematic diagram for being molded wind frame；
Fig. 2 is the structural schematic diagram of plastics frame body；
Fig. 3 is the structural schematic diagram for blocking cover.
Specific embodiment
As shown, the injection molding wind frame of the fan assembly of the utility model, including use a molding modeling of Shooting Technique
Expect frame body 1, the centre of plastics frame body 1 is equipped with fan mounting holes 3, and elastomer 2 is arranged in the surrounding of plastics frame body 1, and elastomer 2 is adopted
It is molded on plastics frame body 1 with two-shot process, the surrounding of plastics frame body 1 is equipped with injecting hole 8 and allows the elasticity of quadric injection mould
2 partial stowage of body wherein, to improve the connection reliability between elastomer 2 and plastics frame body 1.The back side of fan mounting holes 3 exists
Lower half, which is equipped with, blocks cover 5, blocks cover 5 by plastic material single injection-molded, the outer rim setting peripheral board 10 for blocking cover 5 is trapped among
Outside the protrusion edge 4 of fan mounting holes 3, the outer rim for blocking cover 5 also sets up cutting 6, and the bottom of cutting 6 is equipped with front and back coupler body 9, preceding
Elasticity setting between coupler body 9 afterwards, 1 back side of plastics frame body and 6 corresponding position of cutting are equipped with slot 7, and the lower half in 7 slot of slot exists
Front-rear direction has wider groove width to adapt to the front and back coupler body 9 of elasticity opening, slot 7 and 1 integrated injection molding of plastics frame body.
