Description
Technical field
The present invention relates to a kind of monolayer plastic tube extrusions to finely tune mold, for the extrusion of monolayer plastic tubing.
Background technology
Conventional monolayer plastic tubing is in normal extrusion, it is necessary to the tune of concentricity is manually carried out to tubing plastic layer
Section；And concentricity adjusting often consumes a longer time and generates more tune machine waste material, causes the waste of raw material.And existing rank
Although the extrusion of section is exempted to solve the problems, such as this very well to mold, mold machining technology requirement and processing cost are all very high, in addition
Use environment requirement is harsh so that is unable to popularity use.
Invention content
The technical problem to be solved in the present invention is：Existing monolayer plastic tube extrusion die is overcome in normal extrusion
In the problem of can not quickly adjusting plastic layer concentricity, causing waste of raw materials more, individual layer extrusion is overcome to exempt to process skill to mold
The problem of art requirement is high and of high cost provides a kind of monolayer plastic tube extrusion fine tuning mold, reduces adjusting machine time and raw material
Waste.
In order to solve the above-mentioned technical problem, the present invention proposes following technical scheme：A kind of monolayer plastic tube extrusion fine tuning
Mold, including external mold, core model, tuningout module, several adjusting screws, locked mode plate；
External mold is a revolving body, and center offers the holding tank of a toroidal, the diameter of the holding tank from front end to
Rear end becomes larger；
The front end of external mold is opened up there are one tubular mounting groove, which connects with holding tank；
Several bolt apertures are offered on the antetheca of mounting groove, several bolt apertures are with equal angle and distance compartment of terrain
It is looped around around the center of circle of mounting groove；
The rear end of core model is set there are one mounting disc, and mounting disc is fixed on the rear end of external mold；
Project the molding die body there are one toroidal forwards from mounting disc, the diameter of the molding die body from front end to the back-end by
Gradual change is big；
Molding die body is plugged in holding tank；
Tuningout module is tubular, is mounted in mounting groove；
Several screw through-holes are offered in tuningout module, several screw through-holes are with equal angle and distance compartment of terrain ring
It is wound on around the center of circle of tuningout module；
The inside of tuningout module opens up the container there are one bell shape, and tuningout module is mounted on container when in mounting groove
It is connected with holding tank；
Molding die body is plugged in container；
It is formed between the internal face of the container of internal face, tuningout module in the holding tank of external mold and the outside wall surface of molding die body
One shaping channel；
Several adjusting screw corresponding inserteds are in several screw through-holes and are locked into the bolt apertures of external mold；
Locked mode plate is fixed on the front end of external mold, and tuningout module pressing is fixed in mounting groove；
The center of locked mode plate opens up the feed inlet there are one bell shape, and feed inlet is connected with shaping channel.
Further limit of above-mentioned technical proposal is that the appearance and size of tuningout module is less than mounting groove, tuningout module peace
Certain gap is formed when in mounting groove between mounting groove and tuningout module.
Compared with prior art, the present invention has following advantageous effect：It is squeezed installing and using monolayer plastic tubing of the present invention
Go out before finely tuning mold, mold concentricity can be pre-adjusted by adjusting tuningout module.After installation is complete, basis is only needed
Actual product squeeze out concentricity be finely adjusted again, it is larger reduce adjusting machine time and caused by wastage of material.
The external mold and core model of monolayer plastic tube extrusion fine tuning mold of the present invention are integral structures, during usually use not
Need to split, after for the first time using the concentricity for regulating mold and extruded product, next time is when installing and using again, then without again into
Row adjusts the purpose that just can reach concentricity qualification.

Fig. 1 is the stereogram of monolayer plastic tube extrusion fine tuning mold of the present invention.
Fig. 2 is the front view of monolayer plastic tube extrusion fine tuning mold of the present invention.
Fig. 3 is A-A sectional views in Fig. 2.
Specific embodiment
It please refers to Fig.1 to Fig.3, a kind of monolayer plastic tube extrusion finely tunes mold, including external mold 1, core model 2, tuningout mould
3, six adjusting screws of block（It is not shown）, locked mode plate 5.
External mold 1 is a revolving body, and center offers the holding tank 12 of a toroidal, the diameter of the holding tank 12
It is become larger to the back-end from front end.
The front end of external mold 1 is opened up there are one tubular mounting groove 14.The mounting groove 14 is connected with holding tank 12.
Bolt apertures there are six being opened up on the antetheca of mounting groove 14（It is not shown）.Six bolt apertures（It is not shown）With equal
Angle and distance compartment of terrain be looped around around the center of circle of mounting groove 14.
The rear end of core model 2 is set there are one mounting disc 22, and mounting disc 22 passes through die body lock screw（It is not shown）Installation is fixed
In the rear end of external mold 1.
The molding die body 24 there are one toroidal is projected forwards from mounting disc 22, and the diameter of the molding die body 24 is in the past
End becomes larger to the back-end.
Molding die body 24 is plugged in holding tank 12.
Tuningout module 3 is tubular, is mounted in mounting groove 14.
The appearance and size of tuningout module 3 is slightly less than mounting groove 14, in mounting groove when tuningout module 3 is mounted in mounting groove 14
Certain gap is formed between 14 and tuningout module 3.
Screw through-hole there are six being opened up in tuningout module 3（It is not shown）.Six screw through-holes（It is not shown）With equal
