Description
Technical field
This utility model relates to extrusion molding mould field, concretely relate to a kind of have umbellate form flow dividing structure squeeze
Go out mould.
Background technology
Plastic extruding forming is to make plastics become flow regime by the method for heating, then makes it under certain pressure effect
By mold, through pipe molding, dilate transition, radially expansion shaped insertion-type after prepare continuous print tubing.At thermoplastic pipes
During material extrusion molding, the fused raw material from extruder enters mould, then at the beginning of the circular passage of spreader is allowed to
Step forms the tubular flow of hollow and then enters pipe shaping area extrusion moulding product.The shunting that tradition extrusion molding mould is arranged
Cone, outer surface is smooth, makes the plastic liquid by spreader become the tubular flow of thin ring-type formation hollow, it is simple to add further
Work and plasticizing.Spreader smooth outer surface, when plastic liquid discharges continuously in advance, due to action of gravity, causes spreader bottom
Plastic liquid is piled up, and causes mobility to be deteriorated, serious appearance plastics, reduces the mechanical performance of material, affects molding system
The intensity of product and toughness.
Utility model content
The purpose of this utility model is for above-mentioned deficiency, it is provided that a kind of extrusion die with umbellate form flow dividing structure
Tool, solves spreader bottom plastic liquid in existing extrusion molding mould with expectation and piles up, cause mobility to be deteriorated, reduce goods
The technical problem of mechanical performance.
For solve above-mentioned technical problem, this utility model by the following technical solutions:
A kind of extrusion molding mould with umbellate form flow dividing structure provided by the utility model, including die holder body, shunting
Structure, plug, mouth die, described flow dividing structure includes spreader, spreader support, and spreader support includes inner support, support arm,
Described die holder body is fixedly installed on support arm, and described spreader is arranged on inner support, and spreader is positioned at die holder intracoelomic cavity,
Projection, convex outer surface and die holder intracoelomic cavity surface close-fitting are set on described spreader, between adjacent protrusion, constitute split channel.
Described inner support is connected by shunting muscle with described support arm, and described projection is mated with shunting muscle.
Described projection is equal with described shunting muscle quantity, is uniformly distributed in the form of a ring, and quantity is 4～24.
Described convex surfaces is smooth.
Compared with prior art, the beneficial effects of the utility model are: spreader outer peripheral face arranges projection, adjacent protrusion it
Between form split channel, the plastic liquid entering spreader can be played drainage, simultaneously because of protruding stop, reduce plastics
The phenomenon that fluid is piled up to spreader bottom because of gravity impact；And then improve the plastic liquid mobility by spreader, prevent
Decompose and reduce products machinery performance.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further elaborated.
With reference to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 7, an embodiment of the present utility model is a kind of band umbellate form shunting knot
The extrusion molding mould of structure, including umbellate form flow dividing structure, die holder body 8, plug 9, mouth die 10.Umbellate form flow dividing structure bag therein
Including spreader 1 and spreader support 2, spreader support 2 includes inner support 3 and support arm 4；Shunting 2 is fixedly installed in inner support 3
On, or be overall structure with inner support 3；Outer surface at spreader 1 is disposed radially ganoid protruding 5, quantity
It it is 8；Split channel 6 is formed between adjacent protrusion.Spreader 1 is arranged in the die cavity of die holder body 8, and raw material melt flows into mould
Chamber, is split boring the projection 5 arranged on 1 and imports split channel 6, then flow into the forming cavity between plug 9 and mouth die 10, at its end
End dilates 11 extruding pipe material.
With reference to shown in Fig. 3, Fig. 5 and Fig. 7, in an embodiment of the present utility model, inner support 3 He of umbellate form flow dividing structure
Support arm 4 relies on shunting muscle 7 to connect, and quantity is 8；Protruding 5 arrange position mates with shunting muscle 7, and both the most uniformly set
Put.
In other specific embodiments, the described quantity of protruding 5 may be configured as 4.
In other specific embodiments, the described quantity of protruding 5 may be configured as 24.
Comparison diagram 5 and Fig. 6, spreader 1 outer peripheral face of the umbellate form flow dividing structure in this utility model arranges projection 5, adjacent
Form split channel 6 between projection, the plastic liquid entering flow dividing structure can be played drainage, simultaneously because of protruding resistance
Gear, reduces the phenomenon that plastic liquid is piled up to spreader bottom because of gravity impact；And then improve plastic liquid and pass through flow dividing structure
Mobility, prevent decompose and reduce products machinery performance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
