Abstract
The utility model discloses a kind of devices for eliminating the black line of tube surfaces, belong to tubular object extruding technical field, it is intended to provide a kind of new equipment for improving tube surfaces quality, technical points include tube forming die head, the feed side of its tube forming die head is provided with water conservancy diversion orifice plate, the water conservancy diversion orifice plate is equipped with middle through-hole, and the first deflector hole of water conservancy diversion from inside to outside and the second deflector hole of ecto-entad water conservancy diversion are distributed in middle through-hole periphery；The utility model is processed for plastic pipe.
Description
Technical field
The utility model is related to plastic pipe processing technology, more specifically to a kind of elimination black line of tube surfaces
Device.
Background technology
At present, in process of production, the particularly colourless or light tube surfaces such as PE are often present with plastic pipe product
The phenomenon that black line, since specific Producing reason is not fully aware of, it is difficult to be improved from principle.Tube surfaces it is black
Line although not having big influence to the performance of tubing, to more demanding use occasion, is extremely difficult to presentation quality
Requirement；Moreover, in product testing, as the black line of outer surface reduces the grade of product, cause the drop of value of the product
It is low, influence product quality.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency for the prior art, provide it is a kind of it is simple in structure,
Processing unit (plant) easy for installation, that the black line of tube surfaces can be eliminated.
To achieve the above object, the utility model provides a kind of device for eliminating the black line of tube surfaces, the device bag
The molding die of tubing is included, the feed side of the molding die is provided with water conservancy diversion orifice plate, which is equipped with middle through-hole,
The first deflector hole of water conservancy diversion from inside to outside and the second deflector hole of ecto-entad water conservancy diversion are distributed in middle through-hole periphery.
Further, first deflector hole and the second deflector hole are arranged alternately.
Further, first deflector hole and the second deflector hole are staggeredly uniformly arranged along middle through-hole periphery.
Further, the conicity angles alpha of first deflector hole is 35 °~45 °；The taper angle β of second deflector hole for 35 °~
45°。
Further, the end face of first deflector hole and the second deflector hole is equipped with chamfering.
Advantageous effect
Compared with prior art, the utility model has the characteristics that：
1st, by adding water conservancy diversion orifice plate, the black line of outer pipe wall can be effectively eliminated, promotes the qualification rate of product quality；
2nd, water conservancy diversion orifice plate intermediate symmetry to flow among tubing and the material of outside is uniform, is further ensured that tubing appearance
Face is without black line；
3rd, the deflector hole of water conservancy diversion orifice plate both ends of the surface is uniformly distributed and quantity is consistent so that the material of tubing being capable of held stationary stream
It is dynamic, ensure that tubing thickness is uniform；
4th, the reasonable of water conservancy diversion orifice angle is set so that Flow of Goods and Materials is uniform；
5th, the chamfering in deflector hole passes through the material of tubing and is not detained on water conservancy diversion orifice plate, being capable of smooth flow.
Description of the drawings
Fig. 1 is the schematic diagram of water conservancy diversion orifice plate in the utility model；
Fig. 2 is the left view of water conservancy diversion orifice plate in the utility model；
Fig. 3 is the installation diagram in the utility model.
In figure：1st, molding die；2nd, water conservancy diversion orifice plate；3rd, middle through-hole；4th, the first deflector hole；5th, the second deflector hole；6th, it is solid
Determine portion；11st, injection moulding mould head.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not restricted by specific implementation.
The embodiment of the utility model is such：As shown in Figures 1 to 3, it is a kind of eliminate the black line of tube surfaces method, be
During tube forming, the inside material and outside material that make flowable materials swap.It is the molding die in tubing
In by set a water conservancy diversion orifice plate realize inside material and outside material exchange.
In the present embodiment, the device of the black line of elimination tube surfaces of the above method is realized, including molding die 1, shaping
Die head 1 is connected with injection moulding mould head 11, and the feed side of the molding die 1 is provided with water conservancy diversion orifice plate 2, which sets
Have middle through-hole 3, be distributed in 3 periphery of middle through-hole water conservancy diversion from inside to outside the first deflector hole 4 and ecto-entad water conservancy diversion
Two deflector holes 5, along 3 periphery setting of middle through-hole, interlaced and not intercommunication, described first leads this 8 deflector holes of both ends of the surface
The conicity angles alpha of discharge orifice 4 is 40 °, and the taper angle β of the second deflector hole 5 is 40 °.Then, water conservancy diversion orifice plate 2 is arranged on molding die 1
Runner on, the fixed part 6 of water conservancy diversion orifice plate 2 and 1 clearance fit of molding die are locked by bolt.
It then,, will not when the material of tubing is flowed through on deflector hole plate 2 due to the end face chamfered of deflector hole
There is the phenomenon that stagnant material, it, will when the material of tubing is by this 16 deflector holes, while by outside intermediate flow direction of material tubing
Outside has among the flow direction of material tubing of black line, and then black line is prevented to appear on the surface of tubing, enables the appearance of product
Reach qualified standard, improve the surface quality of tubing.
It the above is only the preferred embodiment of the utility model, it should be pointed out that for those skilled in the art,
On the premise of not departing from the utility model structure, several modifications and improvements can also be made, it is new that these all do not interfere with this practicality
The effect and practical applicability of type.
