Abstract
The utility model discloses a kind of branch pipe type flow passage structures of angle change, include upper and lower die body and mold the manifold flow passage to be formed, the angle of the cross section of drop shaped part angle of the manifold flow passage tapers into, while the area of section of manifold flow passage tapers into from intermediate toward both ends.By the design of modified runner, the flow field end end face section after optimizing is designed using the water droplet cross section of fluid channel of low-angle, and the area of section of entire runner is also gradually reduced, hence it is evident that shortens material in the residence time at runner both ends, extension quantity-produced period.
Description
Technical field
The present invention relates to the runner design of branch pipe in extrusion die, the branch pipe type runner knot of specially a kind of angle change
Structure.
Background technology
In general, in the in-between section of sprue of the branch pipe of extrusion die and end face section in drop shape, water droplet at two
Lower part angle is angularly to design, and is illustrated as shown in Figure 1 and Figure 2, conventional extrusion die, intermediate shape after being molded by upper and lower die body
Into manifold flow passage, melt is from feed inlet into air stream enter runner, and the intermediate cross-section of location A and the end face section of B location are in drop shape, and two
It is angularly to design to locate water droplet lower part angle.Such design residence time of material for runner both ends is long, right
This runner for the raw material that burnt material easily occurs is grown in some residence times and there is defect, can not long-time continuous production,
Cleaning need to be shut down to put into production again, loss is big, and waste is serious.
Invention content
For defect in the prior art, the purpose of the present invention is to provide a kind of branch pipe type runners of angle change
Structure can be obviously shortened residence time of the material at runner both ends, extend the quantity-produced period.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of branch pipe type flow passage structure of angle change includes upper and lower die body and molds the manifold flow passage to be formed, feature
It is：The angle of the cross section of drop shaped part angle of the manifold flow passage tapers into, while branch pipe from intermediate toward both ends
The area of section of runner tapers into.
Preferably, the intermediate cross-section maximum height L0 of the manifold flow passage is between 70mm ~ 140mm, the branch pipe
The end face section minimum altitude of runner is between L1 is 50mm-120mm.
Preferably, the intermediate cross-section runner gap H0 of the manifold flow passage is between 18mm-36mm, the branch pipe stream
The end face section runner gap H1 in road is among 18mm-36mm.
By the design of modified runner, the flow field end end face section after optimizing is cut using the water droplet runner of low-angle
Face is designed, and the drop shape angle of entire manifold flow passage is gradually reduced from intermediate toward both ends, the area of section of entire runner also by
It is decrescence small, hence it is evident that shorten material in the residence time at runner both ends, extension quantity-produced period.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 3-6, a kind of branch pipe type flow passage structure of angle change includes upper die body 1, lower mold body 2 molds shape
Into manifold flow passage 3, material entered from feed inlet 4 in manifold flow passage 3, and manifold flow passage 3 is turned left the right side two in rack-style from centre
Side is unfolded, the intermediate cross-section such as C pointed locations shown in Fig. 3, end face sectional drawing such as D pointed locations.As shown in figure 5, C meanings are
Manifold flow passage intermediate cross-section, intermediate cross-section maximum height L0 is between 70mm ~ 140mm, and intermediate cross-section runner gap H0 is in 18mm-
Between 36mm.The end face section minimum altitude of the manifold flow passage of D meanings is between L1 is 50mm-120mm, between the runner of end face section
Gap H1 is among 18mm-36mm.The angle of the cross section of drop shaped part angle of manifold flow passage 3 is from intermediate location of C toward both ends D
It puts and tapers into, while the area of section of manifold flow passage tapers into.As the angle in the present embodiment is gradually decreased to from 60 degree
36 degree.
By the design of modified runner, the flow field end end face section after optimizing is cut using the water droplet runner of low-angle
Face is designed, and the drop shape angle of entire manifold flow passage is gradually reduced from intermediate toward both ends, the area of section of entire runner also by
It is decrescence small, hence it is evident that shorten material in the residence time at runner both ends, extension quantity-produced period.
The above is only the better embodiment of the present invention, not makees limitation in any form to the present invention, every
Technical principle any simple modification made to the above embodiment, equivalent variations or modification according to the present invention, still fall within this hair
In the range of bright technical solution.
