Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment is being front with technical solutions of the utility model
Put and implement, give detailed embodiment and concrete operating process, but protection domain of the present utility model does not limits
In following embodiment.
A kind of secondary ejection mold with fork ejecting structure, including fixed half and moving half, it is characterised in that: also include pendulum
Bar ejecting mechanism, swing rod ejection mechanism includes c-type fork 9, liftout plate 14, ejector sleeve 61 and curved pin 82, and c-type fork 9 includes swing arm
92, prize arm 93 and moving arm 91, prize arm 93 and be connected with the cushion block 13 on dynamic model by pin with the junction of swing arm 92, sled
The free end of swing arm 93 is connected with the liftout plate 14 arranged on dynamic model, and liftout plate 14 is provided with ejector sleeve 61, and curved pin 82 is by cover half
Substrate 21 stretches to dynamic model, and the vertical section 821 including base portion of curved pin 82 and the tilting section 822 at top, the end of tilting section 822 is stretched
Enter the lower section of the moving arm 91 of c-type fork 9；It is provided with punch core rod 72 on solid plate 22, moving platen 12 is provided with die mould
Core 71, ejector sleeve 61 stretches in die core rod 71 from liftout plate 14, is additionally provided with master slider 4 and secondary slide block 3 on moving platen 12, main
The head of slide block 4 and secondary slide block 3 stretches between punch core rod 72 and die core rod 71, master slider 4 towards punch core rod 72 or
Being provided with protruding 441 on the side of die core rod 71, secondary slide block 3 is close to the opposite side of master slider 4 and is arranged, the afterbody of master slider 4
Being provided with curved pin through hole 41, curved pin 82 passes in curved pin through hole 41, and the afterbody at secondary slide block 3 is provided with guide pillar hole 33, guide pillar
Hole 33 coordinates with the Angle Pin 81 arranged on solid plate 22.
In this programme, master slider 4 and secondary slide block 3 extend between die core rod 71 and punch core rod 72, are i.e. capable of
Injecting products forms the groove-like structure of indent, by arranging protruding 441 on master slider 4, on the sidewall of groove-like structure
Define secondary groove.Under normal circumstances, due to the most vertical pass not parallel with the direction of motion of slide block, indent direction of secondary groove
System, it is impossible to realize the demoulding by conventional method.In this programme, the knockout course of product is as follows: the die sinking first stage, the most tiltedly
Guide pillar 81 is deviate from by guide pillar hole 33, promotes secondary slide block 3, is had in die core rod 71 and punch core rod 72 by the head of secondary slide block 3
Between extract out；Die sinking second stage, the tilting section 822 of curved pin 82 promotes moving arm 91, makes swing arm 92 rotate around pin, prizes arm 93
Free end tilt under the drive of swing arm 92 and prize liftout plate 14, thus drive ejector sleeve 61 that product is released die core rod 71,
Now the secondary groove on product is deviate from by the projection 441 arranged on master slider 4；The tilting section 822 of die sinking phase III curved pin 82
Push the sidewall of curved pin through hole 41 on master slider 4, master slider 4 is extracted out by between die core rod 71 and punch core rod 72, now
The die cavity of mould fully opens, and product realizes the demoulding.By coordinating of swing rod ejection mechanism and master slider 4 and secondary slide block 3 action,
First being deviate from protruding 441 by product, then extract out from side by slide block, solving this series products cannot the situation of the demoulding.
Being provided with thimble 62 in ejector sleeve 61, the afterbody of thimble 62 is connected with the top board arranged on dynamic model substrate 11.Thimble 62
Be designed to realize again ejecting product by the ejecting mechanism of injection machine, after die sinking, again product is ejected mould
Chamber, it is achieved the demoulding completely.
Master slider 4 includes the hyoplastron 44 of head and the drive block 43 of afterbody, by location between hyoplastron 44 and drive block 43
Pin 42 connects, and hyoplastron 44 stretches in the middle of die core rod 71 and punch core rod 72, and protruding 441 are arranged on the side of hyoplastron 44, curved
Pin through hole 41 is arranged on drive block 43.Owing to the groove on product under normal circumstances is less, the size of respective slide must be fitted
Should, but slider designs is too small, is on the one hand unfavorable for controlling its action, on the other hand requires the most complicated to manufacturing process,
For convenience of the manufacture of mould, by master slider 4 separately design, it is simple to the maintenance of mould and maintenance, can also take into account its action simultaneously
Accurate control.
Secondary slide block 3 includes the tongue piece 31 of head and the driving plate 32 of afterbody, and tongue piece 31 stretches into die core rod 71 and punch mould
In the middle of core 72, drive and be provided with guide pillar hole 33 on plate 32, the thickness of tongue piece 31 height not less than protruding 441.By pair slide block 3 points
It also is able to equally for designing two portions to play and is easy to the maintenance of mould and maintenance takes into account the effect accurately controlled to its action, tongue
The thickness of sheet 31 height not less than protruding 441, the space that such tongue piece 31 is conceded after extracting out in die cavity just may be used for
Product is deviate from protruding 441, such that it is able to allow master slider 4 smooth opening.
Being additionally provided with latch segment 5 on solid plate 22, latch segment 5 is for buckling master slider 4 and secondary slide block 3 after matched moulds.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment, equivalent and the improvement etc. made within novel spirit and principle, should be included in guarantor of the present utility model
Within the scope of protecting.
