Description
Technical field
Plastic extruder component assembly manufacturing field is the utility model is related to, especially a kind of coaxial-type extruder shunting disk
Assembling structure.
Background technology
The common connection of shunting disk in existing plastic extruder, because the screw rod at this is rotating, to smoothly connect
Refute melting charge, just must separately plus transition apparatus just can, this prolongs after allowing for the connection of the function, will certainly increase various costs simultaneously
Therefore unfavorable factor is produced.
Utility model content
The utility model aims to solve the problem that the above problem, there is provided a kind of coaxial-type extruder shunting disk assembling structure, its nothing
Transition apparatus need to separately be added, can realize and be assembled between rectifying disc and mould, core and fiaring cone, first, shortening the stream of melting charge
Journey and directly it is connected with mould；Second, directly it is connected to form the bending resistance torsional strength that fixed supporting point improves screw rod with inner screw
And assembly precision, the technical solution that it is used are as follows：
A kind of coaxial-type extruder shunting disk assembling structure, it is characterised in that including：It is mould, shunting disk, main barrel, whole
Flow cone, core and inner screw, the shunting disk are mainly integrally formed by cylindrical portion, inner circular part and shunting muscle, and the shunting muscle is extremely
It is uniformly distributed in less for two between cylindrical portion and inner circular part, the mould and main barrel pass through bolt Joint, the shunting
The cylindrical portion of disk is clamped between the first concave mouth of mould and the second concave mouth of main barrel, the inner circular part of the shunting disk
It is threadedly coupled with core, the inner screw and fiaring cone Joint, the inner circular part Joint of the fiaring cone and shunting disk.
On the basis of above-mentioned technical proposal, the fiaring cone is threadedly coupled with the inner circular part of shunting disk, and the spiral shell of fiaring cone
Line rotation direction is consistent with the thread rotary orientation of inner screw.
On the basis of above-mentioned technical proposal, the shunting muscle is four or six.
On the basis of above-mentioned technical proposal, the thread rotary orientation of the fiaring cone and the thread rotary orientation of inner screw are left-handed.
The utility model has the following advantages that：Without that separately plus transition apparatus, can realize rectifying disc and mould, core and whole
Assembled between flow cone, first, shortening the flow of melting charge and being directly connected with mould；Second, directly it is connected to be formed with inner screw
Fixed supporting point improves the bending resistance torsional strength and assembly precision of screw rod.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.It should be evident that drawings in the following description are only
It is a kind of embodiment of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the acquisition that can also be extended according to the attached drawing of offer is other to implement attached drawing.
Fig. 1：The cross-sectional view of the utility model；
Fig. 2：The side structure schematic diagram of shunting disk described in the utility model；
Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that to the utility model
Limitation.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；It can be directly connected, can also be indirectly connected by intermediary.For the ordinary skill in the art,
Concrete meaning of the above-mentioned term in the utility model can be understood with concrete condition.
In the description of the utility model, it is to be understood that the orientation or position relationship of the instruction such as term "left", "right"
It is based on the orientation or position relationship shown in attached drawing 1, is for only for ease of description the utility model and simplifies description, rather than
Indicate or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot
It is interpreted as the limitation to the utility model.
As depicted in figs. 1 and 2, a kind of coaxial-type extruder shunting disk assembling structure of the present embodiment, it is characterised in that bag
Include：Mould 1, shunting disk 2, main barrel 7, fiaring cone 5, core 4 and inner screw 3, the shunting disk 2 is mainly by cylindrical portion 20, interior
Circle portion 21 and shunting muscle 22 are integrally formed, and the shunting muscle 22 is at least two and is uniformly distributed in cylindrical portion 20 and inner circular part 21
Between, by 6 Joint of bolt, the cylindrical portion 20 of the shunting disk 2 is clamped to the of mould 1 for the mould 1 and main barrel 7
It is that shunting disk 2 is closely as one with mould 1 and main barrel 7 between one concave mouth 10 and the second concave mouth 70 of main barrel 7,
The inner circular part 21 of the shunting disk 2 is threadedly coupled with core 4, the inner screw 3 and 5 Joint of fiaring cone, the fiaring cone 5 with
21 Joint of inner circular part of shunting disk 2.
Preferably, the fiaring cone 5 is threadedly coupled with the inner circular part 21 of shunting disk 2, and the thread rotary orientation of fiaring cone 5 with it is interior
The thread rotary orientation of screw rod 3 is consistent.
Preferably, the shunting muscle 22 is four or six.
Further, the thread rotary orientation of the fiaring cone 5 and the thread rotary orientation of inner screw 3 are left-handed.So using left spiral shell
Line, is because inner screw is fixed pole at this time, is passive, and the melting charge from external screw rod is active, is looked from right to left,
Melting charge is rotating counterclockwise, must be just left-hand thread in order to which screw thread does not loosen.By this shunting disk connect as a result, making
Mould, shunting disk, inner screw, main barrel become be fixed as one.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all scopes that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
