Description
Technical field
Section bar field is the utility model is related to, more particularly to a kind of former of arc plastic material.
Background technology
At present, plastic material is usually straight that its production method is：First, plastic raw materials are by extruder heating melting；
Then, in the case where the pressure of extruder promotes, plastic melt is connected to by getting into the mould (being referred to as head) of extrusion machine head, machine
The entrance point section of head is usually round, and the port of export of head is commonly referred to as die lip, and its shape is consistent with final plastic material, but
Size has difference, and head is provided with electric heater unit, is to make the plastic melt in head to keep head certain temperature mesh
It can be flowed in the case where the pressure of extruder promotes；Then, plastics flow out from head, enter back into stock mould and are fixed to section bar, head
Heating is needed to ensure that plastics can flow, and stock mould is then needed to cool down, and while cooling, some is also needed to in stock mould
Section bar imposes vacuum, so as to improve sizing precision；Because moving resistance of the plastics in stock mould is very big, so fixed in order to overcome
The resistance of type, section bar finally can be also pulled at draw-gear, another purposes of draw-gear is, by adjusting traction speed
Degree, to control the size of section bar.
Aforementioned production method is widely used for plastics industry, to produce various plastic materials.This production method production is straight
Section bar has no problem, but if for producing curved section bars, then it is impossible.Specifically, to produce curved section bars, will can typically determine
Pattern is designed to arcuate structure, but by after sizing system design camber structure, plastics draw plastics when by arc stock mould
Power it is bigger, the frictional force between plastics and stock mould also can be bigger, will eventually produce traction self-locking.Therefore, it is general at present
Arc plastic material is produced using Shooting Technique, but Shooting Technique is by the manufacturing cost, machine-shaping efficiency and product of mould
Quality requirement etc. influence, can not widely be used always.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of arc plastic material into
Type equipment.
In order to realize the above object a kind of former of arc plastic material provided by the utility model, including extrusion
Machine, head and stock mould, the entrance point of the head are arranged on the head of the extruder, and the entrance point of the stock mould is straight
Connect on the port of export of the head, the guiding arc of arcuate structure is arranged at intervals with the port of export of the stock mould
Mould, the guiding arc mould include one piece of curved plate and two pieces of guiding arc moulds for being separately positioned on the curved plate both sides
Plate, during production, the one side for the section bar extruded from the port of export of the stock mould and the guiding arc formwork of respective side
Inwall is tangent, from the guiding arc formwork of the another side of the section bar of the port of export extrusion of the stock mould and respective side
Inwall is also tangent.
By the way that stock mould is directly installed on head, and leading for arcuate structure is arranged at intervals at the port of export of stock mould
To arc mould, so, by the straight line plastic material for mold forming of shaping, the guiding arc mould of arcuate structure is forced through, directly
Line plastic material completes bending in the case where being oriented to the guiding of arc mould and extruding, arc plastic material is shaped to, because stock mould is straight
Connect on head, so the frictional force between plastics and stock mould is sufficiently small, therefore need not can draw, will not produce
The problem of drawing self-locking and efficiency high.
In such scheme, the length L of the stock mould is 10~90mm.By by sizing system design enough to short, this
Sample can further reduce the frictional force between plastics and stock mould, be more beneficial for the shaping of arc plastic material, production efficiency
Higher, sizing system design with is traditionally obtained longer correlation by this, and anti-(traditional stock mould is to obtain the high product of precision, general meeting
Sizing system design is obtained longer).
In such scheme, one end of the port of export of the stock mould and the direction stock mould of the guiding arc mould
Between space D be 10~50mm.By by the port of export of stock mould be oriented to arc mould the direction stock mould one end
Between space D be designed to suitably sized, can so reduce the frictional force between plastics and stock mould, and can ensures straight line
Plastic material is being oriented to the more preferable brake forming of energy in arc mould.
In such scheme, the arc chord angle for being oriented to arc mould is θ, 0 ° of 180 ° of ＜ θ ＜.
In such scheme, the height for being oriented to arc formwork is more than the height of the section bar.
In such scheme, the guiding arc mould is externally provided with cooling water tank.
In such scheme, the both ends of the cooling water tank are respectively equipped with water fender.The water fender added can effectively be prevented
Only cooling water flow out of in cooling water tank, meanwhile, stock mould can play a part of preventing cooling water from blowing back into head, moreover it is possible to rise
The heat on head is prevented to isolation, in order to avoid influence to be oriented to brake forming of the arc mould to straight line plastic material.
The beneficial effect that technical scheme provided by the utility model is brought is：
1st, by the way that stock mould is directly installed on head, and arcuate structure is arranged at intervals at the port of export of stock mould
Arc mould is oriented to, so, by the straight line plastic material for mold forming of shaping, is forced through the guiding arc mould of arcuate structure,
Straight line plastic material completes bending in the case where being oriented to the guiding of arc mould and extruding, arc plastic material is shaped to, due to stock mould
It is directly installed on head, so the frictional force between plastics and stock mould is sufficiently small, therefore need not can draw, will not produces
The problem of raw traction self-locking and efficiency high；
2nd, by the way that enough to short, sizing system design so can further be reduced into the friction between plastics and stock mould
Power, the shaping of arc plastic material is more beneficial for, production efficiency is higher, and it is anti-that sizing system design with is traditionally obtained longer correlation by this；
3rd, by the way that the space D between the port of export of stock mould and the one end for the direction stock mould for being oriented to arc mould is set
Count into suitably sized, can so reduce the frictional force between plastics and stock mould, and can ensures that straight line plastic material is being led
To the more preferable brake forming of arc mould interior energy；
4th, the water fender added can effectively prevent cooling water flow out of in cooling water tank；
5th, stock mould can play a part of preventing cooling water from blowing back into head, moreover it is possible to play the heat isolated and prevented on head
Amount, in order to avoid influence to be oriented to brake forming of the arc mould to straight line plastic material.
