Abstract
The invention relates to a once-forming device of a screw type double-wall corrugated pipe. The once-forming device is characterized in that an internal mold and an external mold are sequentially sleeved and connected outside a core mould; an inner-wall solvent material channel is arranged between the core mould and the internal mold; an outer-wall solvent material channel is arranged between the internal mold and the external mold; an inner-wall stock mold is fixed at one end of the core mould; the inner-wall stock mold is sleeved inside a rotary inner-wall screw type stock mold; a screw type groove is formed on the inner wall of the inner-wall screw type stock mold; an air inlet is formed between the inner-wall solvent material channel and the outer-wall solvent material channel, or a suction hole is formed on the groove of the inner-wall screw type stock mold; and double walls are formed by utilizing the blowing action of the air inlet or the suction-gas action of the suction hole. The external mold, the internal mold and the core mould form and extrude a two-double flow passage, the inner-wall stock mold is connected outside the core mould, and the screw type double-wall corrugated pipe can be produced by one time. The once-forming device has the advantages that the structure is simple, the cost is low, the screw type double-wall corrugated pipe can be produced by one time, and the equipment investment is reduced to lower the manufacturing cost and save the resources.
Description
Technical field
The present invention relates to a kind of extrusion molding apparatus of plastic pipe, particularly relates to a kind of one-shot forming apparatus for spiral type double-wall corrugated pipe.
Background technology
At present, in various structural tubes, the double-walled plastic film capicitor is owing to have the ring stiffness height, and is easy to connect, low cost and other advantages, more and more by urban construction, fields such as field irrigation bury the ground draining, blow-off line adopts.But the existing make-up machine of producing the double-walled plastic film capicitor all is that the double-wall pipe of every kind of specification all needs a large amount of forming modules by synchronous circulation mobile module former, complex structure not only, and equipment investment is huge.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, and cost is low, can disposablely produce spiral double-wall corrugated pipe, reduces production costs the one-shot forming apparatus for spiral type double-wall corrugated pipe that economizes on resources to reach thereby reduce equipment investment.
Solution of the present invention is such: the outer end at core is socketed with internal mold and external mold successively, and the molten material passage of inwall is arranged between core and internal mold, and the molten material passage of outer wall is arranged between internal mold and external mold; End at core is fixed with the inwall stock mould, and the inwall stock mould is to be enclosed within the spiral inner wall formula stock mould of rotation, has spiral groove at the inwall of spiral inner wall formula stock mould; Air admission hole is arranged between molten material passage of inwall and the molten material passage of outer wall or suction hole is arranged, utilize the air blowing of air admission hole or the air-breathing effect of suction hole to form double-walled at the groove of spiral inner wall formula stock mould.Extrude two-double flow passage by external mold, internal mold, core formation, the core outer end is connected with the inwall stock mould, on the typing cooler bin rotary spiral inner wall formula stock mould is installed, and once can produce spiral double-wall corrugated pipe.
Advantage of the present invention is simple in structure, and cost is low, can disposablely produce spiral double-wall corrugated pipe, reduces production costs to reach thereby reduce equipment investment, economizes on resources.
Description of drawings
Accompanying drawing is embodiments of the invention.
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment
The present invention is socketed with internal mold 4 and external mold 1 successively in the outer end of core 3, and the molten material passage of inwall is arranged between core 3 and internal mold 4, and the molten material passage of outer wall is arranged between internal mold 4 and external mold 1; End at core 3 is fixed with inwall stock mould 8, inwall stock mould 8 is to be enclosed within the spiral inner wall formula stock mould 10 of rotation, inwall at spiral inner wall formula stock mould 10 has spiral groove, air admission hole 2 is arranged between molten material passage of inwall and the molten material passage of outer wall or at the groove of spiral inner wall formula stock mould 10 suction hole 9 is arranged.
If only adopt the structure that air admission hole 2 is arranged between molten material passage of inwall and outer wall channel, the mode that adopts air admission hole to blow exactly makes inwall be attached to internal mold typing moulding.
If only adopt the structure that suction hole 9 is arranged at the groove of spiral inner wall formula stock mould 10, adopt air-breathing mode exactly, make inwall be attached to internal mold typing moulding.
Between molten material passage of inwall and the molten material passage of outer wall air admission hole 2 is arranged if adopt, the structure of suction hole 9 is arranged at the groove of spiral inner wall formula stock mould 10 again, adopting exactly blows adds air-breathing mode, makes inwall be attached to the internal mold typing.
Described groove can be circular groove or square groove or trapezoidal groove or triangular groove or their combination etc.
In the present embodiment, at the outer wall of interior wall type stock mould 10 sprocket wheel is arranged, the sprocket wheel of interior wall type stock mould 10 outer walls is arranged on the termination, and this gear is connected with power drive mechanism 6, also can adopt gear drive or belt transmission to drive by transmission mechanism and rotate
Using when of the present invention, form the melt of inner and outer wall, can be extruded by the mould shunting by an extruder, also can be extruded respectively by two extruders, can also be that many extruders are extruded jointly.
The melt of extruding by extruder, melt is extruded through outer wall channel and inwall channel, transmission mechanism 6 drives spiral inner wall formula stock mould 10 and rotates, and outer wall melt 7 is sent in the mould with inwall melt 5 simultaneously, produce pressure differential in air admission hole air blowing or the air-breathing mode of suction hole, make outer wall melt 7 in pressure differential is attached to spiral inner wall formula stock mould 10, inwall melt 5 is attached to 8 moulding of internal mold stock mould.
