Description
Technical field
The utility model relates to technical field of plastic production more particularly to a kind of extrusion heads.
Background technique
Extruding machine is the necessaries for producing plastic pipe, and plastics are plasticized by extrusion system into uniform melt, and
It under the established pressure of this process, is continuously squeezed out by screw rod, then by discharging mold and cooling equipment, determines product
Type.Existing extruding machine temperature when by product by squeezing out head extrusion is still higher, and product is easily-deformable before cooling and shaping,
Reduce product quality.
Utility model content
It in order to overcome the defects of the prior art described above, can be with the technical problem to be solved by the utility model is to provide one kind
Guarantee that product squeezes out the extrusion head of quality.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of extrusion head, including head
Main body, the crosshead body are the cylindrical tube that inner hollow and both ends have opening, the inner wall of the crosshead body with
There is circulation chamber for retaining refrigerant, axis twist cloth of the circulation chamber along the crosshead body between outer wall
It sets, the helical angle of the circulation chamber is gradually reduced along plastic extrusion direction.
In an alternative embodiment, the material of the crosshead body is graphene Heat Conduction Material.
In an alternative embodiment, the refrigerant of perforation to the circulation chamber is offered on the outer wall of the crosshead body respectively
Entrance and refrigerant outlet.
In an alternative embodiment, the section of the circulation chamber is circle, and the diameter of the circulation chamber is along plastic extrusion direction
It is gradually increased.
In an alternative embodiment, annular groove is offered on the outer wall of the crosshead body, the annular groove is in crosshead body
Upper arranged for interval.
The utility model has the beneficial effects that: a kind of extrusion head is provided, by opening up on the inner wall of crosshead body
There is the circulation chamber for retaining refrigerant, so that temperature when plastic extrusion is lower, is not susceptible to deform, improves product matter
Amount.
Detailed description of the invention
Fig. 1 show the cross-sectional view of the extrusion head of the utility model embodiment；
Fig. 2 show the structural schematic diagram of the extrusion head of the utility model embodiment；
Label declaration:
1- crosshead body；
2- circulation chamber；
3- annular groove.
Specific embodiment
For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match
Attached drawing is closed to be explained.
The design of the utility model most critical is: by offering on the inner wall of crosshead body for retaining refrigerant
Circulation chamber be not susceptible to deform, improve product quality so that temperature when plastic extrusion is lower.
It please refers to shown in Fig. 1 to Fig. 2, a kind of extrusion head of the utility model, including crosshead body, the crosshead body
For inner hollow and both ends have the cylindrical tube of opening, have between the inner wall and outer wall of the crosshead body for depositing
The circulation chamber of refrigerant is stayed, the circulation chamber is twist arranged along the axis of the crosshead body, the spiral of the circulation chamber
Angle is gradually reduced along plastic extrusion direction.
As can be seen from the above description, the utility model has the beneficial effects that: in use, be passed through refrigerant to circulation is intracavitary,
Plastics are squeezed out from crosshead body, since the helical angle of circulation chamber is gradually reduced along plastic extrusion direction, closer to crosshead body
The plastics cooling efficiency of extrusion is higher, and molding effect is better.
In an alternative embodiment, the material of the crosshead body is graphene Heat Conduction Material.
As can be seen from the above description, the thermal coefficient of graphene Heat Conduction Material less than 1.2, has good capacity of heat transmission,
Further improve cooling efficiency.
In an alternative embodiment, the refrigerant of perforation to the circulation chamber is offered on the outer wall of the crosshead body respectively
Entrance and refrigerant outlet.
As can be seen from the above description, refrigerant inlet is used for the intracavitary input refrigerant liquid of circulation, refrigerant outlet is for defeated
Refrigerant liquid out.
In an alternative embodiment, the section of the circulation chamber is circle, and the diameter of the circulation chamber is along plastic extrusion direction
It is gradually increased.
As can be seen from the above description, designing the plastics cooling efficiency further such that the extrusion closer to crosshead body in this way
Higher, molding effect is better.
In an alternative embodiment, annular groove is offered on the outer wall of the crosshead body, the annular groove is in crosshead body
Upper arranged for interval.
As can be seen from the above description, annular groove reduces wall thickness, improves heat-exchange capacity while saving and use material.

The crosshead body 1 is the cylindrical tube that inner hollow and both ends have opening, the inner wall and outer wall of the crosshead body 1
Between there is circulation chamber 2 for retaining refrigerant, the circulation chamber 2 is twist arranged along the axis of the crosshead body 1,
The helical angle of the circulation chamber 2 is gradually reduced along plastic extrusion direction.
It please refers to shown in Fig. 1 to Fig. 2, the embodiments of the present invention two are as follows: a kind of extrusion head, including crosshead body 1,
The crosshead body 1 is the cylindrical tube that inner hollow and both ends have opening, the inner wall and outer wall of the crosshead body 1
Between there is circulation chamber 2 for retaining refrigerant, the circulation chamber 2 is twist arranged along the axis of the crosshead body 1,
The helical angle of the circulation chamber 2 is gradually reduced along plastic extrusion direction.
The material of the crosshead body 1 is graphene Heat Conduction Material.It offers and passes through respectively on the outer wall of the crosshead body 1
Pass to the refrigerant inlet and refrigerant outlet of the circulation chamber 2.The section of the circulation chamber 2 is circle, the circulation chamber 2
Diameter is gradually increased along plastic extrusion direction.Offer annular groove 3 on the outer wall of the crosshead body 1, the annular groove 3 is in machine
Arranged for interval in head main body 1.
In conclusion the utility model provides a kind of extrusion head, it is used for by being offered on the inner wall of crosshead body
