Specific embodiment
In conjunction with the preferred embodiment and its attached drawing is further non-limitingly described in detail technical solution of the present invention.
As shown in Figure 1 to Figure 3, the present embodiment introduces this secondary demolding mechanism, IGBT module by taking IGBT module side frame as an example
Side frame two sides are provided with elasticity arm 102, and elasticity arm 102 includes cylinder 103 and the buckle 104 being set on cylinder 103.Fig. 4
The mold 200 for forming the IGBT module side frame is shown, secondary demolding mechanism 100 is set to 200 two sides of mold.When demoulding, two
The buckle 104 that secondary demoulding mechanism 100 is capable of effective protection product is not pulled deformation.Cylinder 103 includes side 1031, buckle
104 are arranged in side 1031, and slide block insert 13 includes the mating surface to fit with the side 1031.
Specifically, as shown in Figures 5 to 9, secondary demolding mechanism includes sliding block 10, and sliding block 10 includes being used for IGBT module bullet
The fixed slot 101 of 102 injection molding of the arm of force, sliding block 10 are equipped with inclined guide pillar 11, the spring eye for accommodating spring are provided in sliding block 10,
Sliding block 10 is provided with the first spring 12 to offset with mold, and secondary demolding mechanism 100 further includes slide block insert 13, sliding block 10 and cunning
13 face paste of block mold insert is closed and the two sliding mating.The second spring 14 abutted against with slide block insert 13 is also equipped in sliding block 10, the
Two springs, 14 stroke is shorter than the first spring 12.Slide block insert 13 includes the block button hole 131 for 102 forming shape of elasticity arm, card
Button hole 131 cooperates the card for being molded elasticity arm cylinder 103 and being connected with elasticity arm cylinder 103 with sliding block fixed slot 101 jointly
Button 104.Shape is buckled according to actual module, block button hole may be configured as different shape.When die sinking, sliding block 10 is moved first, later
Slide block insert 13 is moved again.Preferably, 13 rear end of slide block insert is provided with the first convex edge 132, and sliding block 10 is provided with corresponding
Two convex edges 105, sliding block 10 and slide block insert 13 can be carried out mating by the convex edge being mutually clamped and realize synchronizing moving.It is preferred that
, there are a fixed spacings for the first convex edge 132 and the second convex edge 105, it is ensured that slide block insert 13 is in quiet when sliding block 10 starts mobile
Only state.Since the buckle 104 of elasticity arm is embedded in block button hole 131, pull demoulding cannot be directly carried out, therefore, it is necessary to
First sliding block 10 is detached from, then buckle 104 is demoulded from slide block insert 13.
100 side of secondary demolding mechanism of 200 two sides of mold is set to folding for convenience, passes through the oblique of setting side core-pulling
Upper and lower power can be converted to side-to-side movement by guide post 11, inclined guide pillar 11.When initial, the first, second spring 12,14 is in compression
State, when die sinking, in 10 break away from moulds 200 of inclined guide pillar 11 and 12 collective effect sliding block of the first spring, after sliding block 10 starts
It moves back, second spring 14 with slide block insert 13 due to offseting, and slide block insert 13 is stationary at this time, three outsides of elasticity arm 102
Face starts to demould, when sliding block 10 backs to certain distance, it is preferred that when sliding block 10, which retreats, removes block button hole 131, sliding block 10 the
Two convex edges 105 and the first convex edge 132 of slide block insert 13 are matched, under the drive of the second convex edge 105 of sliding block 10, sliding block edge
Part 13 also starts synchronous retrogressing.When fixed slot 101 recesses block button hole 131, elasticity arm cylinder 103 slightly deforms outer, sliding block
Mold insert 13 retreats under the drive of sliding block 10 at this time, and buckle 104 can be demoulded smoothly from slide block insert 13, after sliding block 10 continues
Move back completion demoulding overall process.
The invention has the advantages that sliding block cooperates jointly with slide block insert, and sliding block is first by setting secondary demolding mechanism
Mobile to carry out first time demoulding, after moving a certain distance, slide block insert and sliding block synchronizing moving carry out second and demould, due to the
Primary demoulding and second of demoulding are simultaneously asynchronous, avoid demoulding mechanism from deforming buckle, improve yields.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
