The both ends of wind deflector.
Preferably, it is provided with the insert 12 in the present embodiment for being positioned to the second moulding 50 and core pulling
The second sliding block 60, the 3rd sliding block 70 and the Four-slider 80 of the demoulding.
Preferably, be additionally provided with cover half component 20 for the second moulding 50 is positioned and core_pulling demoulding the 5th slide
The sliding block 100 of block 90 and the 6th, the 5th sliding block 90 are two pieces, and two piece of the 5th sliding block 90 is located at the both sides of the first injection molding cavity respectively, the
Six sliding blocks 100 are located at the side away from the second injection molding cavity of the first injection molding cavity.
The bottom of dynamic model component 10 in the present embodiment sets the (not shown) that has elastic component, the both ends of flexible member
Support respectively on dynamic model component 10 and diving board, it is first when needing to carry out the assembling of the first moulding 40 and the second moulding 50
First the 5th sliding block 90 and the 6th sliding block 100 is controlled to move so that the first moulding realizes core_pulling demoulding, and diving board then is moved into dynamic model
Disassembled on plate 11, now, in the presence of flexible member, the moving die insert 13 and dynamic model being fixed on diving board can make it that
Mold insert 12 separates, and the assembling for the first moulding 40 and the second moulding 50 provides necessary space.Preferably, in the present embodiment
Flexible member be nitrogen spring.
Preferably, the injection mold in the present embodiment also includes thimble (not shown), and the thimble is arranged on dynamic model group
,, can be by the first note by the effect of thimble after the first moulding 40 and the second moulding 50 are completed on part 10
The integrative-structure that the assembling of the moulding 50 of plastic 40 and second is formed jacks up, and is easy to take the integrative-structure using structures such as manipulators
Walk.
According to above-mentioned structure it is recognised that the injection mold in the present embodiment includes solid plate 21, cover half mold insert 22, moved
Mould mold insert 12, the diving board of moving die insert 13, core-pulling mechanism and oil cylinder 321 etc..Wherein, wind deflector is mainly by the second sliding block 60,
Three sliding blocks 70, the demoulding of the inner core pulling of Four-slider 80；Both ends support is mainly taken off by the 5th sliding block 90 and the side core-pulling of the 6th sliding block 100
Mould.
According to another aspect of the present invention, there is provided a kind of in-mould assembly method, the in-mould assembly method utilize above-mentioned reality
The injection mold applied in example realizes that detailed process is as follows：
First stage：After first moulding 40 and the injection of the second moulding 50 are completed, the when pressurize, the cooling scheduled time
After one moulding 40 and the sizing of the second moulding 50, make the core_pulling demoulding of the first moulding 40；During die sinking, solid plate 21 with
Moving platen 11 separates first, now due to injection mold Angle Pin (not shown) drive, the 5th sliding block 90 and the 6th
Sliding block 100 to both sides and axial movement, completes core pulling action respectively.
Second stage：Moving die insert 13 is set to be separated with insert 12.In the presence of nitrogen spring, moving platen 11 and bullet
Plate is separated, and drives moving die insert 13 to be separated with insert 12, and space is provided for follow-up support and wind deflector assembling.
Phase III：Drive the first sliding block 311 to be moved to the direction close to insert 12 using oil cylinder 321, and then push away
Dynamic first moulding 40 is moved with so that the first moulding 40 and the second moulding 50 connect to the direction close to the second moulding 50
It is connected in one.Under the promotion of oil cylinder 321, the first lateral movement forward of sliding block 311, promote support mutually chimeric with wind deflector, complete
It is completed in product mould.
Fourth stage：Resetted using the drive cylinder 321 of control valve 323, and then drive the first sliding block 311 to reset.Product is complete
Be after assembling in Cheng Mo can not ejection device because the rotating shaft of wind deflector both sides be in the first sliding block 311 with support
Corresponding to axis hole 41 within axis hole.In order to smoothly be stripped, after being completed in product mould, and then the first sliding block 311 needs
Original position is returned to, that is, oil cylinder 321 must return to original position before product ejection, rather than as traditional moulds
Original position is returned to again after ejection is completed like that.
5th stage：The integrative-structure that first moulding 40 and the second moulding 50 are connected to formation using thimble jacks up it
After take away.Complete to assemble in wind deflector and both ends supports, and the first sliding block 311 is returned to group after original position by thimble
The product ejection installed, then by manipulator pickup.
6th stage：Matched moulds.After the completion of pickup, matched moulds order is with molding just on the contrary, moving platen 11 is first bonded with diving board
5th sliding block 90 and the 6th sliding block 100 return to original position with moving die insert 13；Now the first sliding block 311 is in original position；
Last solid plate 21 is bonded with moving platen 11, completes matched moulds.
With reference to shown in Fig. 6 to Figure 11, the integrative-structure of injection mold of the invention assembling is by the support and branch positioned at both ends
The mutually chimeric composition of wind deflector between frame.
Axis hole 41 is designed with support, rotating shaft 51 is designed with wind deflector.After support and wind-guiding plate injection moulding, pass through
Mold actions provide active force so that wind deflector rotating shaft 51 is fitted together into rack shaft hole 41, is finally assembling to complete product.
The wind deflector of the present invention is with support in same mold injection.According to the requirement of air conditioner structure, wind deflector, branch can be changed
The quantity and structure of frame.Save original management of product being injected separately, cost of transportation.
The assembling of the multiple wind deflectors and support of the present invention influences packaging efficiency very much.By taking certain split air conditioner as an example：Need
Six wind deflectors are engaged with two supports, and man-made assembly is lost time.Substituted with this structure, achievable wind deflector and support
Assembled in mould, production efficiency is greatly improved.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
(1) acted by adjusting slider position, combination and die sinking, realize and completed with traditional straight panel mould structure
Assembled in moulding mould；
(2) single oil cylinder connects two groups of oil circuits, by adjusting feedback signal, realizes in once molding and is continuously finished forward and back
Two actions；
(3) product is made up of support and wind deflector two parts, and axis hole is designed with support, rotating shaft is designed with wind deflector.
Wind deflector rotating shaft is fitted together among rack shaft hole, is assembled into complete product.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
