Abstract
The utility model discloses a kind of modified extrusion die heads of PE tubing, including extrusion die head ontology, the extrusion die head ontology includes metal mouth mold and metal core die, it is provided with heat conduction layer at the internal voids of the metal mouth mold, side is connected to air inlet communicating pipe at the internal voids of the metal mouth mold, and the other side is connected to right angle escape pipe.In the utility model; the gap of metal mouth mold is provided with heat conduction layer first; and it is communicated with air inlet communicating pipe and right angle escape pipe at gap both ends; the metal mouth mold can be made when being squeezed out for PE tubing; itself carries out air-cooled processing; metal mouth mold is avoided to be in the condition of high temperature for a long time; so that the self-protection effect of metal mouth mold is more preferable; secondly convex block is provided on heat conduction layer; and it is opened up on heat conduction layer fluted; the area of heat conduction layer can be increased so that heat exchange it is more efficient.
Description
Technical field
The utility model is related to PE tubular object extrudings equipment technical field more particularly to a kind of modified extrusion dies of PE tubing
Has head.
Background technology
Mold, in industrial production to be molded, be blow molded, squeeze out, die casting or the methods of forging forming, smelting, punching press obtain
The various moulds and tool of required product, in brief, mold are the tools for making formed article, and this tool is by various
Part is constituted, and different molds is made of different parts, it is mainly realized by the change of physical state of the formed material
The processing of article shape.Blank is set to become the tool for the product for having specific shape and size under external force.It is widely used in punching
The compression moulding of the products such as sanction, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting and engineering plastics, rubber, ceramics
Or in the forming of injection molding, mold has specific profile or cavity shape, can make using the contour shape with cutting edge
By profile wire shaped separation (punching) occurs for blank, blank can be made to obtain corresponding three-dimensional shape using cavity shape
However there is some shortcomingss in use for the extrusion die head of existing PE tubing, die head is in length
Time is under high temperature, be easy to cause itself and is damaged so that the PE tubing effects of extrusion are bad.
Utility model content
Purpose of the utility model is to solve disadvantage existing in the prior art, and a kind of PE tubing for proposing changes
Into type extrusion die head.
To achieve the goals above, the utility model uses following technical solution：A kind of modified extrusion of PE tubing
Die head, including extrusion die head ontology, the extrusion die head ontology include metal mouth mold and metal core die, the metal mouth
Heat conduction layer is provided at the internal voids of mould, side is connected to air inlet communicating pipe at the internal voids of the metal mouth mold,
The other side is connected to right angle escape pipe, and circular arc-shaped metal baffle is welded at the port of the metal mouth mold.
As further describing for above-mentioned technical proposal：
It is equidistantly welded with multiple convex blocks on the heat conduction layer, and is offered between two convex blocks on heat conduction layer recessed
Slot.
As further describing for above-mentioned technical proposal：
It is supported by support plate at the internal voids of the metal mouth mold.
As further describing for above-mentioned technical proposal：
There are three the support plate is arranged altogether, and spacing is equal between any two for three support plates.
As further describing for above-mentioned technical proposal：
The cross section of the metal mouth mold is ring-shaped hollow structure.
In the utility model, the gap of metal mouth mold is provided with heat conduction layer first, and connect at gap both ends
It is connected with air inlet communicating pipe and right angle escape pipe, the metal mouth mold can be made when being squeezed out for PE tubing, itself is carried out
Air-cooled processing avoids metal mouth mold from being in the condition of high temperature for a long time so that the self-protection effect of metal mouth mold is more preferable, secondly exists
It is provided with convex block on heat conduction layer, and opens up fluted on heat conduction layer, can increase the area of heat conduction layer so that heat is handed over
That changes is more efficient.
Description of the drawings
Fig. 1 be the utility model proposes a kind of PE tubing modified extrusion die head structural schematic diagram；
Fig. 2 is the side view of the utility model metal mouth mold；
Fig. 3 is the structural schematic diagram of the utility model heat conduction layer.
Marginal data：
1- circular arc-shaped metals baffle, 2- heat conduction layers, 3- metals mouth mold, 4- convex blocks, 5- air inlet communicating pipes, 6- extrusion dies
Head ontology, 7- metal core dies, the right angles 8- escape pipe, 9- grooves, 10- support plates.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, the modified extrusion die head of a kind of PE tubing, including extrusion die head ontology 6, extrusion die head
Ontology 6 includes metal mouth mold 3 and metal core die 7, at the internal voids of metal mouth mold 3 in be provided with heat conduction layer 2, metal mouth mold
Side is connected to air inlet communicating pipe 5 at 3 internal voids, and the other side is connected to right angle escape pipe 8, at the port of metal mouth mold 3
It is welded with circular arc-shaped metal baffle 1, metal baffle 1 can make the outgassing direction of escape pipe 8 lead to the both sides of metal mouth mold 3,
It avoids blowing to the mold processed.
It is equidistantly welded with multiple convex blocks 4 on heat conduction layer 2, and is opened up between two convex blocks 4 on heat conduction layer 2 fluted
9, it is supported by support plate 10 at the internal voids of metal mouth mold 3, support plate 10 is altogether there are three settings, and three support plates
10 between any two spacing it is equal, the cross section of metal mouth mold 3 is ring-shaped hollow structure.
Circular arc-shaped metal baffle 1 is so that the wind that right angle escape pipe 8 is discharged arranges the both sides to extrusion die head ontology 6.
Operation principle：In use, using on extrusion die head ontology 6 metal mouth mold 3 and metal core die 7 for PE tubing
Extrusion process is carried out, during extrusion, extraneous cold wind was passed through in air inlet communicating pipe 5 so that the heat on heat conduction layer 2
Amount is timely discharged from right angle escape pipe 8, ensures that 6 temperature of extrusion die head ontology is unlikely to too high.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
