Description
Technical field
It the utility model is related to pipeline manufacturing field, and in particular to the cooling dress cooled down during process pipeline to plastic tube
Put.
Background technology
Having many uses for pipeline is general, is used primarily in feedwater, draining, heat supply, gives gas, long distance delivery oil and natural
In gas, agricultural irrigation, hydraulic engineering and various commercial plants.The species of pipeline is a lot, including laminated plastics pipeline, multilayer
The side wall of plastic conduit is made up of different materials, so the advantages of having multiple material concurrently simultaneously.
At present, laminated plastics pipeline is manufactured by complicated, high processing costs dedicated extruder head and mould,
Ensure the complex operation of the thickness of uniform internal layer and outer layer in production process, it is high to finally result in low production efficiency, production cost.
Application No. 201510004135.X Chinese patent discloses a kind of Double-layer plastic pipe extrusion neck ring mold, solves
Above mentioned problem.This extrusion neck ring mold includes：Mouth mold main body, mouth mold edge body；Mouth mold main body what mouth mold edge body is revolving body, mouth mold master
Body is provided with pressure channel, the first shaping channel, mounting groove and hole for injecting glue；First shaping channel be opened in pressure channel most before
End, and connected with pressure channel；Installation is just located at mouth mold body front end, is connected with the first shaping channel；Mounting groove has one
Mounting groove rear surface, mounting groove rear surface are provided with the first injecting glue runner；Wall between first injecting glue runner and the first shaping channel
At face the first glue injection channel is provided with to rear side；Hole for injecting glue is located in mouth mold main body, hole for injecting glue and the first injecting glue flow passage；Mouth mold
Body is inlayed to be arranged in mounting groove；Mouth mold edge body is provided with the second injecting glue runner；Between second injecting glue runner and the second shaping channel
Provided with the second glue injection channel；First injecting glue runner and the second injecting glue runner formed annular injecting glue runner, the first glue injection channel and
Second glue injection channel forms glue injection channel.When producing double-layer plastic pipeline, internal layer melt enters from pressure channel, subsequently into the
One shaping channel and the second shaping channel, while outer layer melt enters from hole for injecting glue, subsequently into injecting glue runner and glue injection channel,
Finally enter the second shaping channel to pinch, outer layer melt is covered on internal layer melt and is molded.
Although this extrusion neck ring mold can make outer layer melt be attached to internal layer by outer layer melt coated on the outside of inner layer pipe
On pipeline, production efficiency is improved, but this extrusion neck ring mold does not set cooling body, and outer layer melt is molten condition, so
Outer layer melt has higher temperature, when outer layer melt contacts with inner layer pipe, can soften inner layer pipe simultaneously, make inner layer pipe
Deformation, the laminated plastics pipeline finally produced can not keep straight.Secondly, outer layer melt is attached on inner layer pipe, is being drawn
When going out plastic conduit, the outer layer melt not cooled down completely can be scratched, and there are cut, nothing in the laminated plastics pipeline surface eventually formed
Method keeps smooth, influences attractive in appearance.So need a kind of device that can be cooled down at once to the pipeline coated with outer layer melt.
Utility model content
The purpose of this utility model is to provide a kind of plastic tube for cooling down pipeline when coating outer layer melt cold
But device.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of plastic tube cooling device, including frame；Machine
