Technical field
The utility model belongs to plastic pipe technical field of processing equipment, and in particular to a kind of plastic tube cooling water ring.
Background technology
The extrusion equipment of the tubing such as existing PE, PVC, PE, PVC pipe dispensing are plasticized, after mouth mold shaping by high temperature, soon
Fast moment carries out appearance cooling, into vacuum shaping box cooling and shaping, due to from extrusion neck ring mold to vacuum shaping box have one section away from
From can not cool down, the shaping pipe temperature that mouth mold comes out in addition is high, shaping is soft, often makes product surface finish poor, spends
Line, ovality is big, and wall thickness deviation is big, and waste product is more.In the plastic pipe process of the prior art, tentatively molding tubing
Blank is come out by squeezing mouth of pipe mould, use the installation cooling water ring between mouth mold and vacuum shaping box to be cooled down more, cooling water ring
General to be cooled down using the cooling water pipe with chuck, cooling water tube wall is equipped with inlet opening, osculum and 1-2 roads and pipe
The vertical annular water tank of wall, but this sink can not axially flow, so that uniform moisture film, Er Qieyou can not be formed on tube wall
In inlet opening, water intake velocity is uneven, makes coolant-temperature gage, flow velocity into cooling water pipe uneven, easily leads on plastic pipe and occur
Water wave, cut, the big phenomenon of uneven thickness, ovality.
The content of the invention
The purpose of this utility model is to solve the above-mentioned problems, there is provided one kind is of simple structure and low cost, makes cooling water
Cooling water temperature, flow velocity on inside pipe wall is balanced, effectively improves plastic pipe finish and elliptical cooling water ring.
The purpose of this utility model is realized by following technical solution：A kind of plastic tube cooling water ring, including ring set
With water ring body, the ring set sealing is linked in water ring body and leans on into one end of mouth mold, the inner wall and water ring body of the ring set
The cavity for accommodating cooling water is circumferentially formed between outer wall, is provided with cooling water inlet and cooling water outlet on the ring set, institute
The inlet opening for being equipped with circular gap arrangement on water ring body with the cooling water cavity correspondence position is stated, the water ring body is surround
Inner wall is provided with multiple thread groove, and the water ring body is equipped with the osculum of circular gap arrangement away from mouth mold side.
Further, the groove depth of the multiple thread groove is 1~2mm, and groove width is 1~2mm, the flight pitch of multiple thread groove
For 8~15mm, helical pitch is 40~80mm, and multiple thread groove circumferential direction uniform gap is covered with water ring inner body wall, this scheme can be accelerated
Circulation rate of the cooling water in cooling water ring, improves cooling effect.
Further, the water temperature of cooling water is 20 DEG C~25 DEG C in the cooling water cavity.
Further, the ring set is welded as a whole with the water ring body.
Further, the ring set removable seal is linked in the water ring body and leans on into one end of mouth mold.
Further, the water ring body outer wall is equipped with flange, one end cap of ring set and in water ring body close to mouth mold
One end, the other end is connected with flange bolt, and the osculum is on the outside of the flange.
Further, the water ring body is made with ring set of 40 chromium, copper or aluminium.
In use, cooling water enters from the cooling water intake of ring set, cavity is flowed through, is discharged from cooling water outlet, with this
Cooling water circulation is carried out, to ensure that the temperature of cooling water in chuck is in 20 DEG C~25 DEG C, at this time, a part of cooling water is from cooling
Inlet opening on water ring body enters inner wall, flows through multiple thread groove and plastic tube is cooled down, multiple thread groove can rise at this time
To water storage and the effect of guiding current, cooling water is uniformly distributed on inner wall and at the uniform velocity flow, the water by heat exchange can be by
Osculum is discharged, therefore avoids cooling water flow velocity or non-uniform temperature from causing occur water wave on plastic pipe, uneven thickness, ellipse
Spend big phenomenon.
Beneficial effect：The utility model has the advantages of simple structure, it is of low cost, temperature, flow velocity can be formed on cooling water tube wall
Balanced moisture film, quickly cools down, effectively raises plastic pipe finish and ovality.
