In the alternative of the present embodiment,

Die head also includes the positioning component 500 for axially position and radial positioning for being arranged at the outer wall of mold cup 200.

More specifically,

Fig. 2 is refer to, positioning component 500 includes radial direction being arranged at the outer peripheral face of mold cup 200, being abutted against with mold cup 200 Location division 510；And be sheathed on the outer peripheral face of mold cup 200, the axially position portion 520 that is connected with mould room 100.

Wherein, radial positioning portion 510 is set to be uniformly distributed in multiple centering screws of the outer peripheral face of mold cup 200.It refer to Fig. 8, in order to install centering screw, the outer wall of mould room 100 is provided with mounting groove 110, and multiple centering screws are arranged at mounting groove 110 It is interior.Specifically, mounting groove 110 is set to multiple screwed holes of multiple axis direction annular arrays along die head, aligning Screw includes mounting bracket and bolt.Preferably, mounting bracket spiral is connected in screwed hole, and is had in the middle part of mounting bracket There is through hole, bolt stretches into through hole and is connected to the outer peripheral face of mold cup 200, it is further preferable that bolt and the inner surface of mounting bracket Interference fit is threadedly coupled.

Positioning principle on radial positioning portion 510 describes in detail as follows：

The centering screw in radial positioning portion 510 radially applies the active force for pointing to the center of circle in regulation process, multiple Centering screw can be adjusted individually, it is to avoid mold cup 200 is eccentric, to ensure the axle of mould room 100, mold cup 200 and shunt assembly 400 Line is located at same straight line, after the axis for ensuring mould room 100, mold cup 200 and shunt assembly 400 is located at same straight line, Lock multiple centering screws, to complete radial positioning.

Wherein, Fig. 3 is refer to, axially position portion 520 sets and is sheathed on the outer wall of mold cup 200.On the right side of centering screw, mould There is gap, axially position portion 520 stretches into the gap and is bolted in the inner surface of mould room 100 between room 100 and mold cup 200, and And, the gap location between mould room 100 and mold cup 200, mould room 100 and mold cup 200 are respectively provided with L-shaped corner, axially position portion 520 The end face in left side is connected to mould room 100 and mold cup 200.

Positioning principle on axially position portion 520 describes in detail as follows：

The gap that axially position portion 520 is stretched between mould room 100 and mold cup 200, the outer surface in axially position portion 520 and mould The inner surface threaded connection of room 100, thus, in the axial direction, axially position portion 520 is relatively fixed with mould room 100.Also, Gap location between mould room 100 and mold cup 200, mould room 100 and mold cup 200 are respectively provided with L-shaped corner, and axially position portion 520 is left The end face of side is connected to mould room 100 and mold cup 200.Thus, on the premise of being relatively fixed in axially position portion 520 and mould room 100, Axially position portion 520 carries out spacing to mold cup 200 in the axial direction, and to sum up, axially position portion 520 can be in the axial direction Positioning mould room 100 and mold cup 200.

It should be noted that " left side " and " right side " mentioned above, is that, using Fig. 3 as reference, the side of material inlet 101 is a left side, The side of material outlet 301 is the right side.

On the shape and structure of shunt assembly 400, describe in detail as follows：

Shunt assembly 400 includes extruding flow divider 410 and core rod 420 that direction is set gradually along material；

Fig. 5 and Fig. 6 are refer to, flow divider 410 has conical first paragraph 411 and the mould room close to material inlet 101 100 inwalls abut annular second segment 412 and to the direction of material outlet 301 extend the 3rd section 413；Extrude the edge of passage 803 The axis direction annular array of die head is in the second segment 412 of flow divider 410.

The reason for first paragraph 411 of flow divider 410 is set to taper is：

Material enters after extruding cavity 801, is uniformly spread under the active force of the first paragraph 411 of taper to surrounding, makes thing Expect to move to extrusion passage 803, on the one hand avoid material in the invalid accumulation in middle part of first paragraph 411, on the other hand can also add The flowing of fast material.

Fig. 7 is refer to, core rod 420 has with the 3rd section of 413 connector 421 being connected and extended to material outlet 301 Extrusion bar 422, the inwall for extruding outer wall and the mouth mold 300 of bar 422 forms the material outlet 301 of annular.

You need to add is that, the 3rd section 413 of flow divider 410 is connected to form isolation strip with the extrusion bar 422 of core rod 420, The forming cavity 802 of annular surrounds isolation strip.

In the alternative of the present embodiment, water pipe head 930 is provided with the perisporium of base 900, die head component 1000 has There is the circulating cooling system 600 connected with water pipe head 930；

The reason for setting circulating cooling system 600 is：

Need tentatively to cool down the material of high-temperature molten-state during formation of tubes, to increase the viscous of molten state material Degree, reduces mobility, to facilitate the shaping of plastic pipe.

Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly The scope of each embodiment technical scheme of type.
