The extrusion molding of cable and abnormal-shaped section bar, its is simple in construction, and manufacturing cost is low, and small investment is pollution-free, can continuously give birth to
Production, many advantages, such as product quality is relatively stable and production efficiency is high.For the production of tubing, due to tubing tube wall compared with
It is thin, generally require to set screen pack in the head body of mould, screen pack changes direction and the speed of stream, and plastics are melted
The screw of body is changed into linear motion, and can effective impurity screening, form certain pressure, be advantageous to the shaping of tubing.
However, during the use of reality, due to the material containing larger particles shape in plastic melt, prolonged accumulation is easily led
The blocking of screen pack is caused to further result in low production efficiency, it is necessary to periodic cleaning, working service cost is higher, human input is big,
It is inconvenient for use.
【Utility model content】
In view of this, it is overcome the deficiencies in the prior art, the utility model provides a kind of extrusion with double-layer filtering net
Mould, by the setting of double-layer filtering net, the frequency of cleaning screen pack is effectively reduced, production efficiency is improved, reduces life
Production and maintenance cost, product quality is stable, easy to use.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of extrusion die with double-layer filtering net, including be sequentially connected head body, current divider supporting plate and
Mouth mold, the first screen pack is provided with the middle part of described head body one end, the mouth mold is internally provided with plug, the plug
One end of the head body is provided with spreader, the outside of described head body one end is cased with rebound, the transition
The outer end end face of plate is provided with the second screen pack, and the inner homogeneous of the rebound is provided with multiple first heating tubes, the mistake
Paracentral side also ring-wound is provided with electrical heating wire, first heating tube and the electrical heating wire inside cab apron
For the further heating of plastic melt, ensure that plastic melt normally flows in head, improve extrusion molding quality.
Preferably, the mesh diameter of second screen pack is more than the mesh diameter of first screen pack, pass through layering
Filtering, further ensures the exquisiteness of plastic melt, improves the density of plastic, be advantageous to the shaping of product, improve
Product quality.
Further, the inside of the head body is vertically provided with temperature sensor, the measurement end of the temperature sensor
Close to the die cavity of mould, for measuring the temperature of plastic melt, and by measurement feedback to control system, realize to described the
The control of one heating tube and the electrical heating wire, so as to effectively control plastic melt temperature, further improve product into
Type quality.
Further, the inside of the head body is also laterally homogeneous is provided with the second heating tube, ensures plastic melt in mould
Has proper flow in die cavity.
The beneficial effects of the utility model are：(1) by the setting of first screen pack and the second screen pack, realize
Layered filtration, the frequency of cleaning screen pack is effectively reduced, improves production efficiency, reduce production and maintenance cost；(2) lead to
The setting of first heating tube and electrical heating wire is crossed, ensure that the mobility of plastic melt, and can further plastify stream material
Interior bulky grain plastic melt, the blocking of screen pack is reduced, product quality is stable, easy to use, reliable.
