Description
Technical field
The technical field of tubing production application is the utility model is related to, more particularly, to a kind of new PE Seven-hole plums
Pipe mold.
Background technology
PE plum blossoms pipe mold at present, shunting guiding, melt are all carried out in mold residence time by die holder and shunting tip
Too short, shunt pressure is unbalanced, and each forming core rod hydraulic pressure is unbalanced, and cooling velocity differs, and is also easy to produce plasticizing deficiency, each sub-aperture
Discharging speed differs phenomenon, often among endoporus discharging it is very fast, properties of product and less stable, be unfavorable for producing.
Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of new PE Seven-hole plums
Pipe mold, design will increase conveyor screw increase melt plasticizing intensity in die holder, and be advantageous to the stabilization of pressure, meanwhile, it will divide
The tapered distribution of cusp design is flowed, ensures the harmony of raw material discharging, and increase divides water body in forming core rod, ensures plug water
Cold harmony.
The technical solution of the utility model is：A kind of new PE Seven-hole plums pipe mold, wherein, including die body and die body
The conveyor screw external mold of connection, the porous plate being connected with conveyor screw external mold, the changeover portion that is connected with porous plate, it is connected with changeover portion
Set is shunk, shrinks set and preceding flow distribution plate, central peak, the shunting die cavity of shunting tip composition；Central peak and shunting tip group
Tapered structure；
Also include rear flow distribution plate, the runner formed by plug connector, center pitman and location-plate；Also include by core
Rod heat insulating mattress, mouth mold, plug and central core rod into sizing section runner；
Also include outer ring sparger, water cooling is sprayed by outer ring sparger and center plug divides water body and center plug, Fen Shui
The sizing cooling section of rod and plug composition；Center plug divides water body and center plug, divided inside water rod and plug by tapping into outside
Outlet pipe.
Further, the end of described die body is fixed with die body adpting flange.
Plug sealing ring is provided with described plug.
Center bar sealing ring is provided with described center plug.
PE Seven-hole plum pipe molds bottom is additionally provided with thermal insulation board, location-plate, and location-plate is located at mouth mold side, and thermal insulation board is located at
Between location-plate and mouth mold.
The heat-insulated film of water jacket is provided between described mouth mold and outer ring sparger.
Compared with prior art, beneficial effect is：Strengthen plastifying using conveyor screw, strengthen melt plasticizing, lift product
Energy.Loading sharing, avoid middle discharging fast, the slow problem of both ends discharging.Divide water body built in forming core rod, cooling is uniform, lifting production
Product speed of production.Same type plum tube production is suitable for, and production stability can be lifted.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
As shown in figure 1,
1st, the mould mainly forms shown in Fig. 1 structures.
2nd, melt enters mould by the feeding mouth of die body 2, by the shunting die cavity formed by die body 2 and conveyor screw external mold 3,
Shunted, melt will be divided into three stock material streams from one stream, and lateral flow melt is become into screw, realize that melt increases
Strong plasticizing effect.
3rd, stream is rebooted and reached for lateral flow, melt after helical shunt by melt by porous plate 4
Section 5 is crossed, the shunting die cavity formed by shrinking set 6 with the preceding central peak 24 of flow distribution plate 7, shunting tip 23.Central peak 24 with
Shunt tip 23 and form pyramidal structure, bootable melt is balanced to be diverted in the preceding discharge opening of flow distribution plate 7, ensures each discharge opening
Speed it is consistent.
4th, melt flow distribution plate 8 after the arrival of preceding flow distribution plate 7, passes through plug connector 9, center pitman 10 and positioning
Plate shape into runner, carry out stream compression, guiding melt is split into Seven-hole plum dress, then by by plug heat insulating mattress 11, mouth mold
20th, the sizing section runner that plug 14 and center plug 16 are formed, preliminary sizing.
5th, melt, by outer ring sparger 18, plug 14 and center plug 16, is sprayed by preliminary sizing by outer ring sparger 18
Water drenching cooling and center plug divide water body 17 and center plug 16, the sizing cooling section for dividing water rod 15 to be formed with plug 14, center
Plug divides water body 17 and center plug 16, divides water rod 15 with passing through central core by external water inlet pipe and water outlet pipe, current inside plug 14
Rod divides water body 17 and divides 15 special bifurcation structure of water rod to design so that and current first reach central core rod 16 and the caudal end of plug 14,
Then pass through the delivery port close to die body end again, realize that internal balance cools down.Melt by completely cooling, final products completely into
Type, realize the production of PE Seven-hole plum tube products.
