The utility model discloses a kind of PPR pipe co-extruder head, comprise die body, die holder, plug, detachable core rod and head connector, the inside of described head connector is provided with intermediate layer mould, runner is provided with between described plug and detachable core rod, the both sides of described runner are provided with release district, Huan Tu center, the bottom in release district, described Huan Tu center is provided with outlet release district, described detachable core rod is connected with core rod screw thread, release district, described Huan Tu center is arranged between detachable core rod and cylinder manifold, a mouthful mould is provided with before described detachable core rod and cylinder manifold, this PPR pipe co-extruder head, by changing production equipment into two squeezing by single squeezing, making Inner tubing layers be grey skin is white, improve the service life of PPR pipe, use same machine simultaneously, improve production efficiency high, the tube material and tube wall thickness produced is even, double-deck matched moulds is effective, without die parting line.

Description

A kind of PPR pipe co-extruder head
Technical field
The utility model relates to PPR pipe preparing technical field, is specially a kind of PPR pipe co-extruder head.
Background technology
The double-layer coextrusion PPR pipe of producing in prior art, the inside and outside layer material of most of tubing uses same plastic material, thus uses two extruders just can complete extrusion task completely.And the outward appearance of producing white pipe is at present better than gray colored pipe, and on opaqueness, be inferior to grey tubing, sunlight long-term irradiation easily causes white pipe material inner wall to produce moss, therefore same plastics are used will to reduce the service life of PPR pipe in producing, and two layer coextruded plastic tube wave character of the prior art, it mainly adopts two extruders, wherein one is arranged on the center line of unit, molten plastic is clamp-oned the ectonexine of head, and another and central axis, the molten plastic extruded is clamp-oned intermediate layer by the aperture in shunting support ribs.This mode mainly contains following shortcoming: (1) production efficiency is low, and head intermediate layer runner will by the aperture in shunting support ribs, and sectional area can not be excessive, and this will make pressure increase, forms larynx footpath.(2) two extruders layout in 90 °, extruder entrance melt flows direction, intermediate layer and pipe forming direction differ 90 ° of angles, interlayer melted fluid not easily arrives mouth mould on circumference 360 ° of directions simultaneously, easily squeezes flat by mouth mould, make tube wall thickness uneven when particularly just driving.
Summary of the invention
The purpose of this utility model is to provide a kind of PPR pipe co-extruder head, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of PPR pipe co-extruder head, comprise die body, die holder, plug, detachable core rod and head connector, the inside of described head connector is provided with intermediate layer mould, runner is provided with between described plug and detachable core rod, the both sides of described runner are provided with release district, Huan Tu center, the bottom in release district, described Huan Tu center is provided with outlet release district, described detachable core rod is connected with core rod screw thread, release district, described Huan Tu center is arranged between detachable core rod and cylinder manifold, a mouthful mould is provided with before described detachable core rod and cylinder manifold, described shunting body to be arranged on inside described die body and to form die body cavity with described die body.
Preferably, the center line of described intermediate layer mould and the center line of die body are that 30 degree to 60 degree angles are arranged.
Compared with prior art, the beneficial effects of the utility model are: this PPR pipe co-extruder head, by changing production equipment into two squeezing by single squeezing, making Inner tubing layers be grey skin is white, improve the service life of PPR pipe, use same machine simultaneously, improve production efficiency high, the tube material and tube wall thickness produced is even, double-deck matched moulds is effective, without die parting line, the utility model mould is due to core rod, be all thread connection between mouth mould and cylinder manifold, can be for convenience detach, greatly reduce the time of remodeling, save manpower and the energy, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 die body, 2 runners, 3 outlet release districts, 4 mouthfuls of moulds, 5 cylinder manifolds, 6 release districts, Huan Tu center, 7 die holders, 8 head connectors, 9 intermediate layer moulds, 10 detachable core rods, 11 plugs.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, utility model provides a kind of technical scheme: a kind of PPR pipe co-extruder head, comprise die body 1, die holder 7, plug 11, detachable core rod 10 and head connector 8, the inside of described head connector 8 is provided with intermediate layer mould 9, the center line of described intermediate layer mould 9 and the center line of die body 1 are that 30 degree to 60 degree angles are arranged, runner 2 is provided with between described plug 11 and detachable core rod 10, the both sides of described runner 2 are provided with release district, Huan Tu center 6, the bottom in release district, described Huan Tu center 6 is provided with outlet release district 3, described detachable core rod 10 is threaded with plug 11, release district, described Huan Tu center 6 is arranged between detachable core rod 10 and cylinder manifold 5, mouthful mould 4 is provided with before described detachable core rod 10 and cylinder manifold 5, release district, described Huan Tu center 6 to be arranged on inside described die body 1 and to form die holder 7 with described die body 1.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
