Description
Technical field
The present invention relates to a kind of extrusion dies.
Background technique
Extrusion molding (Extrusion Molding) is also known as extrusion molding or extrusion moulding, mainly makes melted by heat
High molecular material under the promotion of pressure, be forced through extrusion die and be shaped to have constant cross-section continuous section bar it is a kind of at
Type method.Extrusion forming process mainly includes the processes such as charging, fusion plastification, extrusion forming, sizing and cooling.
Extrusion molding is a kind of method for processing forming efficiently, continuous, inexpensive, adaptive surface is wide, is that high molecular material adds
Occurs a special kind of skill earlier in work, by development in more than 100 years, extrusion molding was to produce kind most in polymer processing field
Method for processing forming more, variation is most, productivity is high, adaptable, widely used, yield accounts for the largest percentage.It is extruded into
Type is that plastic material processes one of most important form, it is suitable for most of plastic materials in addition to certain thermosetting plasticses,
About 50% thermoplastic articles be completed by extrusion molding, meanwhile, be also largely used to chemical fibre and thermoplastic elastomehc
The molding of property body and rubber product；Extrusion process can produce tubing, bar, plate sheet material, profile shapes, wire and cable shield
The continuous type product of the various forms such as layer, monofilament can also be used to mixing, plasticizing, be granulated, the blending of coloring and high molecular material
It is modified etc..Also, based on extrusion molding, cooperation inflation, stretch the methods of extrusion --- blow molding technique and squeeze
Out --- tentering forming technique is the important method for manufacturing film and hollow product etc..
Key equipment in extrusion molding is extrusion die, but existing extrusion die flow uniformity is poor, and resistance to pressure is also less
It is good, cause the product density produced uneven.
Summary of the invention
An object of the present invention, which is that, provides a kind of extrusion die, the extrusion die make melt more evenly and effectively from
Die body receives heat.
Technical solution is: a kind of extrusion die, including mould main body, and mould main body is made of symmetrical Unit two, and symmetrical two is single
Member is connected as one, and melt operation channel is provided in the mould main body inner wall, and melt operation channel includes that melt inlet is logical
Road, first order homogenizer, second level homogenizer, third level homogenizer and extruding groove, access road and first order homogenizer, entrance
Channel, first order homogenizer, second level homogenizer, third level homogenizer and extruding groove arrange from top to bottom, first order homogenizer
It is one, second level homogenizer is 4, and third level homogenizer is 8, and 4 second level homogenizers are evenly arranged in same level
Position, 8 third level homogenizers are arranged in the same horizontal position, and first order homogenizer is by 4 first melt canals respectively with 4
A second level homogenizer is connected, and each second level homogenizer passes through two second melt canals and two third level homogenizers respectively
It is connected, each third level homogenizer is connected by two third melt canals with extruding groove.
Preferably, the first order homogenizer is first order cylindrical can, second level homogenizer is second level cylindrical can, the
Three-level homogenizer is third level cylindrical can.
Preferably, the first order cylindrical can is greater than second level cylindrical can, it is round that second level cylindrical can is greater than the third level
Tank.
Preferably, the length of 4 first melt canals and section are all the same, the length of 8 second melt canals
And section is all the same, the length of 16 third melt canals and section are all the same.
Preferably, described be connected as connecting by equally distributed fastener.
Compared with prior art, the principle of the present invention and beneficial effect are:
The extrusion die flow uniformity protected using the present invention is good, so that melt more evenly and effectively receives heat from die body
Amount, so that the unit of the product bulk density produced is uniform, the homogeneity of product is good and high pressure resistant.
Detailed description of the invention
Fig. 1 is overall structure cross-sectional view schematic diagram of the present invention；
Fig. 2 is Figure 1A-A structural schematic diagram.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
A kind of extrusion die as shown in Figs. 1-2, including mould main body, mould main body are made of symmetrical Unit two, and symmetrical two
Unit is connected by equally distributed fastener 9, and melt operation channel is provided in mould main body inner wall, which runs channel packet
Include melt inlet channel 1, first order homogenizer 2, second level homogenizer 3, third level homogenizer 4 and extruding groove 8, access road 1
With first order homogenizer 2, access road 1, first order homogenizer 2, second level homogenizer 3, third level homogenizer 4 and extruding groove 8
It arranging from top to bottom, first order homogenizer 2 is one, and second level homogenizer 3 is 4, and third level homogenizer 4 is 8,4 the
Two-stage homogenizer 3 is evenly arranged in the same horizontal position, and 8 third level homogenizers 4 are arranged in the same horizontal position, and the first order is equal
Change device 2 to be connected with 4 second level homogenizers 3 respectively by 4 first melt canals 5, each second level homogenizer 3 passes through respectively
Two second melt canals 6 are connected with two third level homogenizers 4, and each third level homogenizer 4 is logical by two third melts
Road 7 is connected with extruding groove 8.
Symmetrical Unit two is the prior art.First order homogenizer 2 is first order cylindrical can, and second level homogenizer 3 is the
Second level cylindrical can, third level homogenizer 4 are third level cylindrical can, and first order cylindrical can is greater than second level cylindrical can, second level circle
Shape tank is greater than third level cylindrical can.
The length of 4 first melt canals 5 and section are all the same, and the length of 8 second melt canals 6 and section are homogeneous
Together, the length of 16 third melt canals 7 and section are all the same, so that melt is had no chance, transverse shifting is to influence adjacent stream
Line.
The use of first order homogenizer 2, second level homogenizer 3, third level homogenizer 4 helps to eliminate the dynamic of melt inflow
Amount, while melt is redistributed, make melt more evenly.
By the setting of three-level homogenizer and three-level melt canal, so that melt more evenly and effectively receives heat from die body
Amount, to ensure that the product quality produced.
Setting of the invention minimizes the collective's cavity area for being exposed to melt pressure, therefore mold also has high voltage
And production capacity, equally distributed fastener enhance the intensity of extrusion die.
