Abstract
Hot runner system is squeezed out, the present invention relates to hot flow path processing technique fields, refer in particular to one kind in machining process is squeezed out, are aided with the extrusion hot runner system of hot flow path.It is achieved by the following technical solution：Squeeze out hot runner system, it is made of extruder, machine head port mould, shaping equipment, bosh, draft gear and cutter device, extruder, machine head port mould, shaping equipment, bosh, draft gear and the cutter device sequentially connects, and hot runner system is provided on the shaping equipment.The present invention breaches traditional extrusion die feature, and using the combination of hot runner system and extrusion die mold, this structure solves the phenomenon that plastic cement freezes off inside extrusion die, maintains that plastic cement temperature is properly uniform, ensure that the quality of product quality.
Description
Technical field
The present invention relates to hot flow path processing technique fields, refer in particular to one kind in machining process is squeezed out, are aided with heat
The extrusion hot runner system of runner.
Background technology
Hot flow path processing technology be by injection molding machine by after processing plastic grain heat method come ensure runner and
The plastics of cast gate are kept molten by being molded.However, in machining process is squeezed out, in the front end of extruder, it is equipped with
Extrusion die, extruder are got a lot of applications, in plastic pipe by extrusion die extruding pipe material, section bar etc. in terms of aluminium
Also there is a large amount of application in terms of material processing.It mainly by the change of molding Material Physics state realize article shape
Processing.But it during processing is squeezed out, is frequently encountered due to the difference of the heat conductivity of machined material, is squeezing out
The port of export of mold will appear moulding material hardened beforehand, squeeze out difficulty so as to cause extruder, shaped article quality is unstable
The problems such as presence.To find out its cause, it is then because the machined material temperature in extrusion die declines so that extrusion die goes out
Moulding material near mouthful has begun to harden, and extruded velocity reduces, and then subsequent moulding material is made to be difficult to normal pass, makes
Near exit moulding material into extrusion die is accumulated.
Invention content
It is an object of the invention to overcome above-mentioned shortcoming of the prior art, and provide a kind of in extrusion processing technology
In the process, it is aided with the extrusion hot runner system of hot flow path.
The present invention is achieved through the following technical solutions：Hot runner system is squeezed out, by extruder, machine head port mould, sizing
Device, bosh, draft gear and cutter device composition, the extruder, machine head port mould, shaping equipment, bosh,
Draft gear and cutter device sequentially connect, and hot runner system is provided on the shaping equipment.
The shaping equipment is made of extrusion model cavity and extrusion die core, extrusion die core be placed in squeeze out model cavity it
It is interior, and squeezing out the molding channel B of product A are stayed between model cavity and extrusion die core；The hot runner system by temperature controller,
Fire-bar and heating rod composition, fire-bar, which is distributed in, squeezes out model cavity surrounding, and heating rod is arranged on extrusion around extrusion die core
On model cavity, fire-bar and heating rod are electrically connected with temperature controller.
The present invention breaches traditional extrusion die feature, utilizes the combination of hot runner system and extrusion die mold, this structure
It solves the phenomenon that plastic cement freezes off inside extrusion die, maintains that plastic cement temperature is properly uniform, ensure that the excellent of product quality
Matter.
Description of the drawings：
Attached drawing 1 is flow sheet of the present invention；
Attached drawing 2 is schematic structural view of the invention.
Specific embodiment：
See attached drawing 1~2, squeeze out hot runner system, filled by extruder 1, machine head port mould 11, shaping equipment 2, bosh 3, traction
Put 4 and cutter device 6 form, the extruder 1, machine head port mould 11, shaping equipment 2, bosh 3, draft gear 4 and cut
It cuts device 5 sequentially to connect, hot runner system 20 is provided on the shaping equipment 2.
The shaping equipment 2 is placed in extrusion model by extrusion model cavity 21 and extrusion die core 22, extrusion die core 22
Within chamber 21, and the molding channel B of product A are stayed between model cavity 21 and extrusion die core 22 squeezing out；The hot flow path system
System 20 is made of temperature controller 201, fire-bar 202 and heating rod 203, and fire-bar 202, which is distributed in, squeezes out 21 surrounding of model cavity, heating
Stick 203 is arranged on around extrusion die core 22 and squeezes out on model cavity 21, and fire-bar 202 and heating rod 203 are electrically connected with temperature controller 201
It connects.
When applying the invention, extruder 1 by the machine head port mould 11 of its front end by the plastic cement of molten condition in extruder 1
It squeezes into the channel B between the model cavity 21 of shaping equipment 2 and extrusion die core 22, due to being installed in 22 surrounding of extrusion die core
There is heating rod 203, heated by heating rod 203 and the inside plastic cement of extrusion die is kept to be always maintained at molten when squeezing out
State, the curing of plastic cement when preventing from squeezing out.Fire-bar 202 is installed on model cavity 202 is squeezed out, is made for the constant temperature of mold exterior
With plastic cement in mold being kept to be constantly in molten condition, and pass through bosh 3, draft gear 4 and cutter device 6, most
Product A is formed afterwards.
