Abstract
The utility model discloses a kind of extrusion die with two-sided die lip runner, include upper die body, wherein protrude on front side of upper die body and form upper die lip, extrusion die also includes lower mold body and lower die lip, described lower die lip embeds the fore-end being arranged on lower mold body, described lower die lip upper and lower surface is die lip runner, wherein one side is smooth planar structure, another side is concavo-convex rib flow passage structure, install corresponding with upper die lip upward by needing the die lip flow passage structure producing product, gap between this die lip flow passage structure and upper die lip upward forms the discharging opening of melt.This utility model just can be used for producing the product of two kinds of different sizes by the simple handling of a die lip, need not look for supporting die lip again, save the time, also save mould material data simultaneously, also save parking space.
Description
Technical field
This utility model relates to a kind of extrusion die, particularly relates to a kind of extrusion die with two-sided die lip runner.
Background technology
The die lip of one side typically it is provided that on conventional extrusion die, the such as die head disclosed in publication number CN,
Runner on its die lip is for carrying straight guide barrel construction.When changing the die lip of other structure runners, need to disassemble whole die lip
After, replace with the die lip of another structure.Existing die lip is all one side flow passage structure, changes inconvenience, economical not,
Also parking space is occupied.
Utility model content
The purpose of this utility model is to provide a kind of extrusion die with two-sided die lip runner, die lip is provided with two-sided
Flow passage structure, may be used for producing the product of different size with a die lip, and operation is changed convenient, simple and practical.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of extrusion die with two-sided die lip runner, includes upper die body, wherein protrudes on front side of upper die body and forms upper mold
Lip, extrusion die also includes lower mold body and lower die lip, it is characterised in that: described lower die lip embeds before being arranged on lower mold body
End portion, described lower die lip upper and lower surface is die lip runner, and wherein one side is smooth planar structure, and another side is recessed
Convex tendon bar flow passage structure, it would be desirable to the die lip flow passage structure producing product is installed corresponding with upper die lip upward, this die lip upward
Gap between flow passage structure and upper die lip forms the discharging opening of melt.
Preferably, described die lip front end has avoiding hollow groove, and it is interior by lower mold that installation bolt stretches into the installing hole on avoiding hollow groove
Lip and lower mold body connect fixing.
Use the extrusion die of said structure, the upper and lower surface of die lip is set to the flow passage structure of different size, the most just
It is that a die lip has double-sided runner structure.The when of needing to change, it is only necessary to disassemble die lip, by the runner of die lip another side
Structure is corresponding with upper die lip, forms new melt tapping channel after installation.This utility model is simple by a die lip
Handling just can be used for producing the product of two kinds of different sizes, need not look for supporting die lip again, save the time, also save simultaneously
Mould material data, also saves parking space.
Accompanying drawing explanation
Fig. 1 is that structure of the present utility model is intended to；
Fig. 2 is side structure schematic diagram of the present utility model；
Fig. 3 is lower mold body STRUCTURE DECOMPOSITION figure of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ 3, a kind of extrusion die with two-sided die lip runner, include on front side of upper die body 1, upper die body 1 convex
Go out and form upper die lip 11.Also include lower mold body 2 and lower die lip 3, embed at described lower mold body 2 fore-end and be provided with lower mold
Lip 3, described lower die lip 3 upper and lower surface is die lip runner, and wherein one side is smooth planar structure 31, and another side is recessed
Convex tendon bar flow passage structure 32, it would be desirable to the die lip flow passage structure producing product is installed corresponding with upper die lip 11 upward, and this is upward
Gap between die lip flow passage structure 31 or 32 and upper die lip 11 forms the discharging opening 10 of melt.
In the present embodiment, charging aperture 30 is arranged in lower mold body 2, and the charging aperture of lower mold body 2 connects between upper and lower die body
Runner 20, then from discharging opening 10 out.
In the present embodiment, described lower die lip 3 front end has avoiding hollow groove 33, installs bolt 34 and stretches on avoiding hollow groove 33
In installing hole, lower die lip 3 and lower mold body 2 are connected fixing.
The when of needing to change, it is only necessary to disassemble lower die lip 3, by the flow passage structure of lower die lip 3 another side and upper die lip
Correspondence, forms new melt discharging opening after installation.
Claims (2)
1. the extrusion die with two-sided die lip runner, includes upper die body, wherein protrudes on front side of upper die body and forms upper die lip,
Extrusion die also includes lower mold body and lower die lip, it is characterised in that: described lower die lip embeds the front end being arranged on lower mold body
Part, described lower die lip upper and lower surface is die lip runner, and wherein one side is smooth planar structure, and another side is concavo-convex
Rib flow passage structure, it would be desirable to the die lip flow passage structure producing product is installed corresponding with upper die lip upward, this die lip stream upward
