Abstract
The invention provides an internal-heating-type extruding device, comprising a flange disc, a machine head connecting body, a pressing cover, an opening module, a core rod and a sprue spreader, wherein the flange disc is sleeved on the outer side of the machine head connecting body, and the opening module is sleeved inside the machine head connecting body and is tightly buckled by virtue of the pressing cover; the sprue spreader is fixed inside the machine head connecting piece through a flat key; the core rod is connected with the sprue spreader through a bolt, is sleeved in the opening module and is fixedly connected with the machine head connecting body by a fastening bolt; a mounting hole is formed in the middle of the core rod; and a heating device is distributed inside the mounting hole. The internal-heating-type extruding device has the beneficial effects that grain materials are heated from outside to inside in a heating cavity before extrusion molding, and the heating device in the core rod also can be used for heating the grain materials from inside to outside in an extrusion process, so that the heating and fusing degree of the grain materials inside are more uniform, raw materials are sufficiently fused, the quality of a tubular product produced by the extrusion molding process is good, and the performance of the tubular product is stable; and the heating equipment is convenient to maintain, is easy to operate and has high yield.
Description
Technical field
The invention belongs to the plastic pipe manufacture field, especially relate to a kind of plastic pipe extruder internal heating type extrusion device.
Background technology
In recent years, be that master's thermoplastic occupies more and more important position with the resin synthetic material in people's life, its process equipment and processing technology are also progressively promoting.Especially aspect the preparation of plastic pipe, novel plastics such as PVC, PE, PPR have progressively replaced metallic conduit with its superiority.So just the quality of production, yield rate, the stability of plastic pipe are had higher requirement.
Feed particles need be carried out dehumidifying, heating earlier in the general plastic tube process, and processes such as extrusion modling, setting wherein will heat in heater before extruding, and the heating of this process is owing to be in the heating chamber of certain volume, to accomplish.Because the outer wall that is heating chamber heats granular materials, inner particle is heated the degree of melting maybe be inhomogeneous, causes small number of materials fully not melt, and uneven particle may appear in the tubing inside of output when extrusion modling.Particulate fraction on these tubing brings hidden danger possibly become blow-up point in the future to use.Therefore how will be that major issue to be solved is arranged more fully with uniformly granular materials being heated.
Summary of the invention
The problem that the present invention will solve provides a kind of internal heating type extrusion device, especially is fit to plastic pipe extruder more fully, equably granular materials is heated.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of internal heating type extrusion device, comprise ring flange, head connector, gland, mouthful mould, plug, branch flow cone, and said ring flange is socketed in the said head connector outside; Said mouthful of die sleeve is connected in the said head connector and with said gland fastening; Flow cone was fixed in the said head connector with flat key in said minute, and said plug is connected with bolt with said minute flow cone, and said plug is socketed in the said mouthful of mould and fixes with fastening bolt and said head connector; Be provided with installing hole in the middle of the said plug, arrange heater in the said installing hole.
Further, said gland and said head connector are fixed with bolt.
Further, in said mouthful of mould, be provided with temperature sensor.
Further, said heater is heating chip or heater coil.
Further, the heating-up temperature of said heater is 135～185 ℃.
Advantage and good effect that the present invention has are: owing to adopt technique scheme; Before the extrusion molding not only in heating chamber ecto-entad granular materials is heated; Heater in the extrusion in plug is also from inside to outside to particle heating, and the degree that inner particle is heated melt is more even, and raw material fully melts; The pipe workpiece quality of output is good when extrusion modling, stable performance; Firing equipment is easy to maintenance, and is easy to operate, and yield rate is high.

The specific embodiment
As shown in Figure 1; The present invention relates to a kind of internal heating type extrusion device, comprise ring flange 1, head connector 3, gland 6, mouthful mould 7, plug 8, divide flow cone 2, said ring flange 1 is socketed in said head connector 3 outsides; Said mouthful of mould 7 is socketed in the said head connector 3 and with said gland 6 fastenings; Flow cone 2 usefulness flat keys 4 were fixed in the said head connector 3 in said minute, and said plug 8 is connected with said minute flow cone 2 usefulness bolts, and said plug 8 is socketed in the said mouthful of mould 7 and with fastening bolt 5 and said head connector and fixes; Be provided with installing hole in the middle of the said plug, arrange heater 10 in the said installing hole.
Said gland 6 can use bolt 9 fixing with said head connector 3, also can select other setting elements such as alignment pin, positioning key.
In said mouthful of mould 7, be provided with temperature sensor, forming temperature is monitored.Simultaneously temperature sensor also has been installed, has been convenient to whole heating-up temperature monitoring at other heating regions.The monitoring control of the temperature tactility apparatus in the whole work flow concentrates on the control platform, and the realization multistation is controlled simultaneously.
Said heater 10 is heating chip or heater coil.The advantage of heating chip is a rapid heat dissipation, and area of dissipation is big; The advantage of heater coil is that the thermal efficiency is high.The two all needs external power supply so that the energy of heating to be provided.Lead-in wire is drawn the back through the junction between each parts and is connected with external power supply.
The heating-up temperature of said heater 10 is for being controlled at 135～185 ℃; Heating-up temperature before this temperature range also is applicable to and extrudes in the heating chamber; For reaching better molding effect; Temperature is too high when preventing to extrude makes the tubing fusion be difficult to moulding, and the temperature range of heater is preferably 145～155 ℃.
Owing to added inner heating device; Plastic pipe before extrusion molding not only in heating chamber ecto-entad granular materials is heated, the heater in the extrusion in plug is also from inside to outside to particle heating, the degree that inner particle is heated melt is more even; Raw material fully melts; The pipe workpiece quality of output is good when extrusion modling, stable performance, and yield rate is high.
The course of work of this instance: with PE-RT tube forming process is example, and its processing and forming step is following:
Step 2. starts extruder, and each section of extruder and each zone of mould are heated to design temperature stage by stage, and heating chip (or heater coil) temperature will be a little less than other thermals treatment zone in the plug, and are incubated a period of time;
The tubing that step 5. is extruded directly gets into vacuum sizing device, and inject water in the process of sizing and lower the temperature, and with after the cooling of vacuum cooled chamber shower water.
(cutting, coil pipe or measured length cutting) handled in the shaping of step 7. finished product.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
