Description
Technical field
The invention belongs to extruder technology field more particularly to a kind of plastic extrusion forming devices.
Background technique
In recent years, it is obtaining wideling popularize development and make in China with the thermoplastic material of the synthetic materials such as polyvinyl chloride resin
With process equipment and processing technology just improve and improve gradually, and especially in terms of plastic conduit production, PE, PVC, PPR etc. are new
Plastic just substitutes rapidly virgin metal pipeline with its brilliant advantage.Raising and product with plastic extruder power
Regenerated plastics micelle is added in composition of raw materials, in process of production to the extruding pipe material surface smoothness of extruder, stability is mentioned
Higher requirement is gone out, production product qualified rate is also required to improve.
In the prior art, the internal model of plastic extruder extrusion die outlet end and external mold are all metal material, any surface finish
It is poor to spend, and coefficient of friction is also larger, will directly influence surface and the interior finish of plastic conduit in this way.Further, since PE
Material viscosity is higher, is easy and mold adhesion, poor fluidity, it is easier to cause plastic pipe rough surface, cause product qualified
Rate is low, and service life is short.
Summary of the invention
The present invention provides a kind of plastic extrusion forming device, is squeezed with solving current plastic extruder in above-mentioned background technique
Mold outlet end out, it is low that there are product qualification rates, the short problem of service life.
Technical problem solved by the invention is realized using following technical scheme: the present invention provides a kind of plastic extruder
Molding machine, it is characterised in that: including extruder body, extruder shell, molding machine, set on the outside of the extruder body
There is extruder shell, one side outlet end is connected with forming device, and the molding machine includes internal model adjustment bar, import department, delays
Portion, forming part, internal model, attachment device, plug, mouth mold, fixing piece, screw, regulating device, external mold adjusting block, external mold are rushed, it is described
Internal model is located at molding machine and extruder body junction, is internally provided with internal model adjustment bar, and its exterior is equipped with import departments, described
External mold is located at the outside of import department, and the mouth mold is located at the other side of internal model, and its exterior is equipped with forming part, the plug is located at mouth
In the junction of mould and internal model, and run through mouth mold, buffer part connection import department and forming part, the attachment device be located at
The outside in type portion, the fixing piece are located at the outside of attachment device, are fixed by screws on molding machine, set between external mold
There is external mold adjusting block, the low side of the external mold adjusting block is equipped with regulating device.
The internal model adjustment bar is equipped with 4.
The external mold adjusting block is equipped with 4.
The mouth mold is made of the material of polytetrafluoroethylene (PTFE).
The plug is made of the material of polytetrafluoroethylene (PTFE).
The invention has the benefit that
Mouth mold and plug is made using polytetrafluoroethylene (PTFE) in 1 this patent, keeps surface inside and outside it smooth, effectively reduces processing
The flow resistance of plastics, mobility is high, effectively extends the service life of molding machine, traditional molding machine is solved, because of flowing
Property is poor, easily causes plastic pipe rough surface, causes product qualification rate low, the short problem of service life.
It is equipped with internal model adjustment bar in the internal model of 2 this patents, the size of import department can be adjusted by adjusting internal model adjustment bar,
And then the size of molding machine shaped article is adjusted, the time of disassembly molding machine replacement internal model is saved, the work of product is greatly improved
Make efficiency.
It is equipped with external mold adjusting block in the external mold of 3 this patents, the ruler of buffer part can be adjusted by adjusting external mold adjusting block
It is very little, replacing construction is saved, the working efficiency of product is further increased.
4 this patents are integrally fixed the part in molding machine using fixing piece, can be effectively prevented due to machine operation
Influence of the vibration of generation to processing plastic pipe, further prolongs the service life.
The structure of 5 this patents is simple, and all parts, which are all made of, to be detachably connected, and keeps its installing and dismounting simple, easy to repair,
Greatly reduce mechanical maintenance cost.
6 this patents are equipped with buffer part between import department and forming part, flow into after so that processing plastics is come in from import department
During type portion, due to the effect of buffer part, so that processing plastics flowing is more steady, while also making to process plastics stream
Speed is accelerated gradually, improves its Forming Quality.
