Embodiment two:
As shown in Figs. 8 to 11, compared with embodiment one, except that: the present embodiment have employed two groups of injection die cavities
Mould and two groups of blowing cavity moulds, often group injection swaging die and one group of blowing cavity mould pairing, realize note by corresponding gyroaxis
The revolution of blow-molded neck finish Hough mold insert 5；Further, two groups of injection swaging dies are adjacently positioned, and two groups of blowing cavity moulds are positioned at described
The outside of two groups of injection swaging dies, the injection entrance 61 of described injection molding channel 6 is placed in the middle, and all of injection outlet 62 is arranged symmetrically in
The both sides of its injection entrance 61.
The work process of the present invention is: matched moulds, injection die cavity cover half 3 and corresponding note blow-molded neck finish Hough mold insert 5 and note
Plastotype core 9 composition closes injection mould, the inside and outside mould of blowing cavity 41 and 42 and corresponding note blow-molded neck finish Hough mold insert and blown type
Core 10 forms blow molding die, and the plastic warp injection molding channel 6 plastified injects injection mould, and temperature control is shaped then die sinking, after moving clamping plate 2
Moving back, injection core 9 and note blow-molded neck finish Hough mold insert 5 are deviate from from injection die cavity cover half 3 with bottle embryo 27, then, and rotating disk top
The piston rod going out piston cylinder 19 is protruding, is driven the note blow-molded neck finish Hough mold insert being positioned on injection-moulding position by rotary disk basement 20
Bottle embryo 27 is deviate from from injection core 9 by 5, and then, under the effect of external force, gyroaxis 7 turns round, and rotating disk 8 turns round 180 °, will band
The note blow-molded neck finish Hough mold insert 5 having bottle embryo 27 forwards corresponding blow molding position to from corresponding injection-moulding position, meanwhile, is blowing
The note blow-molded neck finish Hough mold insert 5 moulded on position forwards corresponding injection-moulding position to from blow molding position, and then, rotating disk ejects piston cylinder
19 drive the rotating disk 8 on rotary disk basement 20 and rotary disk basement 20 to retreat puts in place, matched moulds again, and injection mould injection temperature control sizing is blown simultaneously
Moulding swaging die matched moulds, then, bottle embryo 27 is stretched to the bottom of blowing cavity model cavity, then, compression sky by stretching knock-pin 12
Gas is blown out from blowing core 10 by gas circuit, by bottle embryo 27 inflation molding, obtains mold bottles 28, blows after terminating, blowing
Mould is opened, and after injection end and blowing action all terminate, die sinking, moving clamping plate 2 retreats, injection core 9 and note blow-molded neck finish
Hough mold insert 5 is deviate from from injection die cavity cover half 3 with bottle embryo 27, and blowing core 10 and the note blow-molded neck finish at blow molding position are breathed out
Husband's mold insert 5 is deviate from from blowing cavity mould with mold bottles 28, and then, bottleneck backs down piston cylinder 24 action, and bottleneck backs down work
The piston rod of plug cylinder 24 backs down wedge 11 with bottleneck and stretches into the oblique guide groove of the note blow-molded neck finish Hough mold insert 5 on blow molding position
In until note blow-molded neck finish Hough mold insert 5 is opened, then, stretching knock-pin 12 head on the bottom of mold bottles 28 by molding
Bottle 28 is deviate from from blowing core 10, then, allows bottleneck back down wedge 11 and stretching knock-pin 12 retreats, it follows that rotating disk
Eject piston cylinder 19 to eject, drive the note blow-molded neck finish Hough mold insert 5 being positioned on injection-moulding position by bottle embryo 27 by rotary disk basement 20
Deviating from from injection core 9, mold bottles 28 is taken off from stretching knock-pin 12 by the note blow-molded neck finish Hough mold insert 5 of blow molding position
Under, then, gyroaxis 7 turns round, and rotating disk 8 turns round 180 °, by the note blow-molded neck finish Hough mold insert 5 with bottle embryo 27 from corresponding note
Moulding position and forward corresponding blow molding position to, meanwhile, the note blow-molded neck finish Hough mold insert 5 on blow molding position is from blow molding position
Forwarding corresponding injection-moulding position to, then, rotating disk ejects the piston rod of piston cylinder 19 and puts in place with rotary disk basement 20 and rotating disk 8 retrogressing,
Matched moulds again, carries out next circulation.
In sum, only presently preferred embodiments of the present invention, not it is used for limiting the scope that the present invention implements, all depends on
Equalization change and the modification that shape, structure, feature and spirit described in scope of the invention as claimed is made, all should be included in this
In the right of invention.
