Background technology
Because HDPE enhancing winding structure pipes (Type B) (hereinafter referred to as carat pipe) use hot Wrapping formed, welded seam matter
Amount is high, and ring stiffness is high, and tubing bell and spigot is using same material electric smelting connection, it is ensured that the ne-leakage of joint 100%, will not be because of running
Fluid leaks and causes road surface to collapse in journey.Carat pipe can effectively overcome the bad geology of condition, be built suitable for sponge city
If therefore it is widely used in recent years.The high rigidity performance of carat pipe is mainly formed by compound ribbed pipe and seamless inwall
Pipe shaft structure provided.First hot PE sheet materials are wound on particular manufacturing craft, form seamless carat pipe PE internal layers, while by PP
Single-wall corrugated pipe is sent into cladding extrusion die, and coating mould extrudes certain thickness PE and is coated on PP single-wall corrugated pipe appearances
Face, compound ribbed pipe is formed, synchronous transport is simultaneously wound on the hot PE internal layers for being wrapped in particular manufacturing craft surface, waits to melt cold
But a carat pipe pipe shaft structure is formd afterwards.But when carat pipe ribbed pipe is wound on particular manufacturing craft, PE material are coated on PP single wall ripples
There is certain gap in line tube outer surface, easily sent pipe position-limited wheel to squeeze by for adjusting carat pipe ribbed pipe pitch and direction
Pressure, cause external sheath PE thickness to differ or gauffer, make PP single-wall corrugated pipes eccentric, and ribbed pipe produces gas after being wound in mould
Bubble, the outward appearance of carat pipe is not only influenceed, the ring stiffness of tubing is had an effect on, certain hidden danger to pipe performance be present.
Utility model content
The utility model provides a kind of HDPE ribbed pipes coating mould, using the formed in mould HDPE ribbed pipes ring stiffness height not
The flat situation about collapsing of bubble, ribbed pipe occurs.
In order to reach above-mentioned technique effect, the technical solution of the utility model is as follows：
A kind of HDPE ribbed pipes coating mould, including PP single-wall corrugated pipes enter tube chamber, PE clads extrusion road, PP single wall ripples
Pipe enters tube chamber both ends and offers PP single-wall corrugated pipes inlet and outlet, and PP single-wall corrugated pipes pass through under the drive of the Wound Dies of outside
Both ends PP single-wall corrugated pipes inlet and outlet move in PP single-wall corrugated pipe inlet pipes intracavitary, and PP single-wall corrugated pipes enter in PP single-wall corrugated pipes
Both ends PP single-wall corrugated pipes are sealed when moving in tube chamber to import and export so that PP single-wall corrugated pipes enter tube chamber and form a sealing structure；PE
The discharging opening in clad extrusion road is close to the outer wall of the certain PP single-wall corrugated pipes of PP single-wall corrugated pipe inlet pipe intracavitary, PE claddings
An inlet and outlet of the discharging opening in layer extrusion road in PP single-wall corrugated pipes inlet and outlet, another PP single-wall corrugated pipes import and export institute
Coating mould side wall outside be provided with sealing mechanism, be additionally provided with for being connected with the external equipment vacuumized outside the side side wall
Vacuum adapter.
Further, the sealing mechanism is one layer of vaccum pressing plate, offers PP single-wall corrugated pipes inlet and outlet, vacuum thereon
Pressing plate is fixed by screws on coating mould.
Further, the vaccum pressing plate is additionally provided with one layer of silica gel piece, and vaccum pressing plate and silica gel piece are stacked and passed through
Screw is fixed on coating mould.
Preferably, the screw is hexagon socket cap head screw.
Further, be provided with control valve on the vacuum adapter, and by vacuum pipe with it is external vacuumize set
Standby connection.
Further, the PP single-wall corrugated pipes enter tube chamber both ends PP single-wall corrugated pipes inlet and outlet be centrally located at same water
On flat axis.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：
During using the utility model mould, when PP single-wall corrugated pipes pass through ribbed pipe coating mould through vaccum pressing plate, silica gel piece
When, extrusion PE is coated on PP single-wall corrugated pipes outer surface, while opens external vaccum-pumping equipment, by ribbed pipe coating mould intracavitary
Air taken away through vacuum pipe, take the partial air in cladding PE and PP single-wall corrugated pipes gap away, so that outer layer PE is tight
Patch is coated on PP single-wall corrugated pipes outer surface, forms clad；It is the pipe ribbed pipe roundness that makes to produce, ring stiffness performance, outer
It is better than traditional mode of production to see, and solve ribbed pipe it is flat collapse, ribbed pipe bubble, the problems such as ring stiffness is low, performance is unstable.
