Enough guarantee the Structure explosion diagram under lock sheet opening state；
Fig. 2 be in embodiment 1 a kind of knock-pin fast assembling disassembling structure of injection molding machine in the case where poke rod is in -90 degree states,
It can guarantee the Structure explosion diagram under lock sheet closed state.
In attached drawing: ejection cylinder piston rod 1, liftout plate 2, knock-pin 3, the first hex bolts 4, fixing seat 5, axis hole 6, rotation
Shaft 7, the first inner groovy 8, connecting shaft 9, the second hex bolts 10, lock banking stop 11, convex block 12, lock sheet gland 13, third spiral shell
Bolt 14, arc-shaped through-hole 15, poke rod 16.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1:
As shown in Figure 1 and Figure 2, the knock-pin fast assembling disassembling structure of a kind of injection molding machine provided in this embodiment, including ejection oil
Cylinder piston rod 1, the liftout plate 2 being mounted on ejection cylinder piston rod 1 and knock-pin 3 pass through the first hexagonal on liftout plate 2
Bolt 4 is fixed with fixing seat 5, and the axis hole 6 for fixing knock-pin 3 is equipped in the fixing seat 5, energy is equipped on knock-pin 3
The two sides of enough rotary shafts 7 rotated in axis hole 6, the rotary shaft 7 are equipped with the first inner groovy 8, the rotary shaft 7 and knock-pin
It is equipped with the connecting shaft 9 that diameter is less than rotary shaft 7 between 3, is equipped with one in the two sides of fixing seat 5 and extend into fixing seat 5
And cooperate the second hex bolts 10 of limitation knock-pin rotation with the first inner groovy 8, it is equipped with above fixing seat 5 and is placed on connecting shaft
It can be equipped with outside 9 and in lock sheet when knock-pin 3 pulls out around the lock banking stop 11 of 9 axle center of connecting shaft rotation, be located at first
Convex block 12 in inner groovy 8 is externally provided with lock sheet gland 13 in lock banking stop 11, and the lock sheet gland 13 passes through third bolt 14
It is fixed in fixing seat 5, is equipped with arc-shaped through-hole 15 in the side of lock sheet gland 13, being equipped on the outside of lock banking stop 11 can be in arc
Movement changes nyctitropic poke rod 16 in shape through-hole 15.
Further, the lock sheet is can to lock the knot of knock-pin 3 when stirring 16 90 ° of rotations of poke rod counterclockwise
Structure.
Working principle: when installation, fixing seat 5 is fixed on liftout plate 2 first by the first hex bolts 4, then will
Lock banking stop 11 is put in fixing seat 5, and then lock sheet gland 13 is pressed together on lock banking stop 11, and solid by third bolt 14
It is fixed, guarantee by the limit of lock banking stop 11 in fixing seat 5, and the poke rod 1 on lock banking stop 11 can move in arc-shaped through-hole 15
It is final that poke rod 16 is driven to rotate, and guarantee during installation, poke rod 16 is in the direction position of attached drawing 1, guarantees locking at this time
The convex block 12 of two sides is parallel with the second hex bolts 10 of 5 two sides of fixing seat in piece 11, then will be in the first of 3 two sides of knock-pin
Two convex blocks 12 under groove 8 and original state are in same level, and knock-pin 3 slowly first runs through lock sheet gland 13, so
Run through lock banking stop 11 afterwards, finally extend into axis hole 6, finally screwed using the second hex bolts 10 of two sides and extend into ejection
In 3 corresponding two the first inner groovies 8 of bar, finally knock-pin 3 is limited, lock banking stop 11 is stuck in outside connecting shaft 9 at this time, so
16 90 ° of poke rod rotations (as shown in Figure 2) are stirred counterclockwise afterwards, so that the convex block 12 of 11 two sides of lock banking stop is from original level
Setting, becomes and is vertically arranged, and is at this time to be vertically arranged with the first inner groovy 8 of two sides, finally locks knock-pin 3, then
When needing to dismantle knock-pin 3, first the second hex bolts 10 of two sides is unclamped, and rotary dial poke rod 16 arrives the position of Fig. 1
It sets, the operation for directly tearing topping rod 3 open can be realized, therefore installation and the disassembly in later period are facilitated by said structure design,
And it is stronger after installing.
