Description
Technical field
It the utility model is related to a kind of extrusion molding pipe shaping mould, more particularly to a kind of HDPE double-layer composite pipes extruded mould；
Belong to extrusion molding pipe shaping mould.
Background technology
HDPE (high density polyethylene (HDPE)) two-layer compound extruded pipe is a kind of widely used plastic tube, each by two extruderses
Extrusion cladding in two-layer compound pipe mold is squeezed into respectively from after by two kinds of different plastic molten melts to form.
Two-layer compound pipe mold is generally mainly by external mold, the internal model in the external mold, the shunting being fixed in the internal model
Device is formed.At present, the runner of traditional moulds is all shorter, causes that the moisture in raw material can not be removed fully, raw materials melt is not filled
Point, influence pipe workpiece quality；Although although lengthen runner, improve temperature can eliminate the defect, but can cause die size it is larger,
Energy resource consumption raises.In addition, traditional moulds, which also exist, is forced through the defects of small, raw materials melt is uneven.
The content of the invention
In order to overcome defect present in prior art, the utility model, which aims to provide one kind, can effectively improve pipe workpiece quality
HDPE double-layer composite pipe extruded moulds.
To achieve these goals, the utility model uses following technical scheme：It includes the internal model being located in external mold；Institute
State external mold by be docked and connected with forming die sleeve shaper, the right end cap that the shaper compresses formed, the internal model by
The sizing core rod being docked and connected with formation die core is formed；Runner is formed between forming die sleeve and formation die core, shaper is with determining
Sizing runner is formed between pattern core；Current divider is fixed with the left end of formation die core, the conical surface of the current divider is distributed with and flowed
The helicla flute of road connection, current divider are compressed by the shunt cover for being fixed on forming die sleeve left end；Injection nozzle connects with helicla flute, into
Pattern puts the outer layer material inlet with flow passage, there is the colorant inlet with sizing flow passage on shaper；Point
There is heater the inside of stream device and formation die core.
The inwall of forming die sleeve is wavelike structure, and the outer surface of formation die core is wavelike structure；Runner is dumbbell shaped
Structure.
Compared with the prior art, the utility model is by adopting the above-described technical solution, the conical surface in current divider adds
Groove helicla flute, therefore both added flow channel length, extended raw material heated time, the moisture in raw material can be allow fully to arrange
Remove, raw materials melt it is more uniform, will not cause again die size increase, energy consumption rise.Further, since groove helicla flute is distributed in point
The conical surface of device is flowed, therefore the back pressure of mould can be increased, improve product surface more finish, the composite pressure of increase material.
The utility model has many advantages, such as simple in construction, easy to use, cost is low, good product quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Shunt cover 1, forming die sleeve 2, outer layer material inlet 3, road 4, colorant inlet 5, shaper 6, right-hand member
Lid 7, sizing core rod 8, heater 9, sizing runner 10, inwall 11, formation die core 12, outer surface 13, current divider 14, helicla flute
15th, transition runner 16, injection nozzle 17, left end cap 18.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1：There is internal model in external mold.The external mold by be docked and connected with forming die sleeve 2 shaper 6, should
The right end cap 7 that shaper compresses is formed, and the internal model is made up of the sizing core rod 8 being docked and connected with formation die core 12；Shaping
Formed between die sleeve 2 and formation die core 12 between runner 4, shaper 6 and sizing core rod 8 and form sizing runner 10, the sizing
Runner connects with runner 4.Current divider 14 is fixed with the left end of formation die core 12, the conical surface of the current divider is distributed with and runner 4
The helicla flute 15 of connection, current divider 14 are compressed by the shunt cover 1 for being fixed on the left end of forming die sleeve 2；The shunt cover and shunting
Gap between device 14 forms the transition runner 16 connected with helicla flute 15.Injection nozzle 17 is fixed on current divider by left end cap 18
Connected on lid 1 and by transition runner 16 with helicla flute 15.There is the outer layer material inlet 3 connected with runner 4 on forming die sleeve 2,
There is the colorant inlet 5 connected with sizing runner 10 on shaper 6；The inside of current divider 14 and formation die core 12 has heating to fill
Put 9.
In order to ensure that two kinds of raw materials possess certain fusion space, raising composite effect, the inwall 11 of forming die sleeve 2 uses
Wavelike structure, the outer surface 13 of formation die core 12 use wavelike structure；Inwall 11 cooperatively forms dumbbell shaped with outer surface 13
The runner 4 of structure.
