Detailed description of the invention
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
Injection blow molding machine capstan head as shown in Figure 1, including triangle rotating disk 1 be separately positioned in 1 three flank side surface 2 of rotating disk
Some plugs 3, three flank side surface 2 of described rotating disk 1 are respectively arranged with at least two groove 4, are additionally provided with one and connect each
First elongated slot 16 of groove 4, is coaxially arranged with cylinder sleeve 5 in described groove 4, being provided with in cylinder sleeve 5 can along cylinder sleeve 5 in axial sliding
Piston 6, is provided with the first push pedal 7 in described first elongated slot 16, this first push pedal 7 and each piston 6 phase in same flank side surface 2
Supporting, described rotating disk 1 bottom surface is provided with some air vents 8, rotating disk 1 is internally provided with the gas communicated with air vent 8 one_to_one corresponding
Road 9, gas circuit 9 extends to groove 4 bottom surface, communicates with cylinder sleeve 5 inside, in three flank side surface 2 of described rotating disk 1 the most removably
Being provided with mandrel holder 10, mandrel holder 10 is provided with the plug installing hole 11 relative with the first elongated slot 16, described plug 3 is fixing to be set
Putting in plug installing hole 11, plug 3 tail end and the first push pedal 7 offset.
Plug 3 is fixedly installed on mandrel holder 10, and mandrel holder 10 is detachably connected in the flank side surface of rotating disk 1.When
The when of needing to change plug 3, it is only necessary to being pulled down by mandrel holder 10, the plug 3 the most more renewed and mandrel holder 10, by new core
Rod seat 10 is installed in the flank side surface of rotating disk 1 the most permissible.
One piece of core rod installing plate also it is detachably provided with between described any side side 2 and corresponding mandrel holder 10
12, this core rod installing plate 12 is connected in flank side surface 2, is provided with at least two relative with the first elongated slot 16 in core rod installing plate 12
Push rod slideway 13, be respectively arranged with push rod 14 in each push rod slideway 13, push rod 14 offsets with the first push pedal 7, described core rod pacify
Second elongated slot 17 connecting each push rod slideway 13 it is provided with, in the second elongated slot 17 on the face that dress plate 12 is relative with mandrel holder 7
Being provided with the second push pedal 15, the second push pedal 15 offsets with each push rod 14.
Core rod installing plate 12 is arranged between mandrel holder 10 and rotating disk 1, expands the periphery of rotating disk 1, makes shorter plug 3
Close to mould, and match with mould, thus realize the function regulating plug 3 with the spacing of mould.
Being respectively arranged with four grooves 4 and two gas circuits 9 in the described each flank side surface of rotating disk 12, every gas circuit 9 connects two
Individual groove 4 and an air vent 8.So can reduce the quantity of air vent 8, make bottom rotating disk 1 more succinct.
Further, described air vent 8 is connected to the midpoint of gas circuit 9, so gases at high pressure to be made to arrive at biphase simultaneously
In logical groove 4.Improve the synchronicity of corresponding two-piston 6.
Described piston the 6, first push pedal 7, push rod the 14, second push pedal 15 and plug 3 are located in the same horizontal plane, and improve and pass
Dynamic precision.
The operation principle of the present invention is: injection blow molding machine capstan head as shown in Figures 1 to 3, the plug 3 points in its three flank side surface 2
Not corresponding injection molding station, blow molding station and unloading station, once, capstan head can drive plug 3 to turn by equidirectional to every folding mould
A dynamic station, the plug 3 being positioned at injection molding station is without air supply, after the plug 3 being positioned at injection molding station has been molded, plug
The type embryo that can overlap tubular on 3 turns to blow molding station, after the blow mold matched moulds of blow molding station, and plug 3 and/or blow molding die
Having and heat type embryo, then air vent 8 can be supplied by the feeder of injection blow molding machine, and gases at high pressure enter groove 4 through gas circuit 9, push away
Piston 6 in dynamic cylinder sleeve 5 moves forward, and piston 6 is by proposing that push pedal 7 promotes the valve stem 18 of plug 3 rear end (such as Fig. 2 institute
Show), or piston 6 promotes the valve stem 18 of plug 3 rear end (such as Fig. 3 by the first push pedal 7, push rod 14 and the second push pedal 15
Shown in), thus open the gas circuit of plug 3, gas just can enter type embryo, is blow molded into the shape of blow mold die cavity.
When plug 3 changed by needs, directly mandrel holder 10 is removed, the plug 3 the most more renewed and mandrel holder 10, when
The new plug 3 changed is too short, it is impossible to when coordinating with shape mould, increases and install core rod installing plate 12 between mandrel holder 10 and rotating disk 1,
To extend the length of plug 3.Enable to match with corresponding mould.
