Utility model content
For the deficiencies in the prior art, this utility model provides the elastomeric bladder of a kind of note cooling water to cool down in tubing
The extruder in portion is with uniform cooling and shaping device.
For achieving the above object, this utility model provides following technical scheme: a kind of uniform cooling and shaping of extruder
Device, including water-cooled casing, spray head and elastomeric bladder, also includes water pump, and described water pump one end connects cooling water source, the other end
Connecting and have sealed tube, described sealed tube is connected through the die head of extruder with described elastomeric bladder, and described elastomeric bladder is positioned at water cooling box
The die head of internal and close extruder, described elastomeric bladder is additionally provided with the first return duct, described first backflow at the homonymy of sealed tube
Pipe is provided with overflow valve.
By using technique scheme, the cooling water pump in cooling water source is entered elastomeric bladder by water pump, and tubing is being extruded
After the die head extrusion of machine, it is enclosed within elastomeric bladder, thus can realize cooling purpose within tubing so that tubing is cooled
Cheng Zhong, is cooled down, and uniformly, tubing does not haves ununiform shrinkage, thereby may be ensured that tubing in cooling
Well-formed；Overflow valve on first return duct is time in elastomeric bladder, water is enough, and pressure makes overflow valve open overflow, unnecessary water
Enter the first return duct from elastomeric bladder, so can ensure that elastomeric bladder is in all the time and completely rise by state but do not rupture；Thus may be used
To ensure tubing sizing uniformly.
Further, described first return duct is led to cooling water source by elastomeric bladder.
By using technique scheme, after overflow valve is opened, water flows into the first return duct and is then return to cooling water source,
Thus can be with recycle-water resource, it is to avoid waste.
Further, described first return duct is provided with precooling device, and described first return duct screw arrangement is in pre-cooling
On radiator cooler.
By using technique scheme, because the cooling water in elastomeric bladder can carry out heat exchange with tubing, so cooling

Minimizing equipment, it is also possible to reduce its energy expended, energy-conserving and environment-protective；What the setting of water-cooled casing bottom angled and lowest part were arranged returns
Discharge orifice is the most used cooling water in can collecting and discharge water cooling box body；Similarly, return port connects the second return duct, and second
Return duct is led to cooling water source by the return port in water cooling box body, and such water flows into the second return duct and is then return to cooling water source,
Thus can be with recycle-water resource, it is to avoid waste.
Further, described second return duct screw arrangement is in precooling on device.
By using technique scheme, because the cooling water in water cooling box body can carry out heat exchange with tubing, thus cold
But coolant-temperature gage can raise, and uses precooling device again to be cooled down by the cooling water in the second return duct and returns cooling water source, this
Sample will not change the temperature of cooling water source because of the coolant-temperature gage of backflow than the high of cooling water source, and the water yield in the second return duct
Seldom, it is not required to the cooling through long-time cooling or very low temperature, so separately first precools, it is possible to the saving energy, with energy-conservation
The theory of environmental protection is consistent.
Further, described cooling water source is coated with heat-insulation layer.
By using technique scheme, the outer sheathed heat-insulation layer of cooling water source can freeze to certain journey at chiller
After degree, chiller is closed, and utilizes the heat-insulating property that heat-insulation layer is good to carry out constant temperature insulation, is so greatly saved the energy, with
Energy-conserving and environment-protective theory is consistent.
Further, it is provided with, on the downside of corresponding elastomeric bladder, the bracing frame supporting tubing in described water cooling box body.
By using technique scheme, tubing is through elastomeric bladder, and bracing frame supports tubing makes it be unlikely to deform, this
Sample can ensure that when cooling, also will not deform outside tubing, thus ensures that tubing cools down quality.
In sum, the cooling water pump in cooling water source is entered elastomeric bladder by water pump, and tubing is extruded at the die head being extruded machine
After, be enclosed within elastomeric bladder, thus can realize cooling purpose tubing within so that tubing in cooling procedure, outside with
Inside is all cooled down, and uniformly, tubing does not haves ununiform shrinkage, thereby may be ensured that the well-formed of tubing in cooling；The
Overflow valve on one return duct is time in elastomeric bladder, water is enough, and pressure makes overflow valve open overflow, and unnecessary water enters from elastomeric bladder
Enter the first return duct, so can ensure that elastomeric bladder is in all the time and completely rise by state but do not rupture；Thus can ensure that tubing
Sizing is uniformly；The reflux that many places are arranged is all based on the theory of energy-conserving and environment-protective and designs, and entirety reaches uniformly to shape and energy-conservation
The purpose of environmental protection.
