Background technology
Extrusion bar production is that pellet is added into hopper, and plastic pellet is melted and moulded by the heated and shear action of screw rod
Change, be in bar-shaped by extrusion die, into cooler-shaper, from outward appearance to inner essence solidification is cooled down and is molded.In head and cooling and shaping
Thermal baffle, also referred to as heat insulating washer are placed between mould, it, which is acted on, mainly makes to be formed substantially between head and cooler-shaper
Cold and hot interface.If cooler-shaper is joined directly together with head, head temperature on the one hand can be reduced, plastics is blocked in head
Exit, bar are squeezed and not come out；On the other hand, the temperature of cooler-shaper can be raised, makes bar cooling deficiency, produces flash and show
As making bar not produce.Generally, in the prior art, typically head and cooler-shaper are completely cut off with insulating collar, every
Heat pad circle selects fluoroplastics, such as PTFE.The characteristics of PTFE is energy high temperature resistant, and thermal conductivity factor is small, has non-stick, self lubricity
And elasticity, the surface quality of bar is not interfered with, but it also has the shortcomings that obvious, i.e. and PTFE hardness is not high, there is creep, when
Clamp bar volatile circle when screw pressure adjusts uneven.Temperature be higher than 250 DEG C when again easily deformed damaged, and price is very
It is expensive, it is impossible to reuse, the mould that particularly a mould has more, because insulating collar loss is big, it is necessary to frequently change heat insulating washer and right
Mould safeguarded, thus caused by equipment stop work and had a strong impact on production efficiency, on the other hand, the cost depletions of heat insulating washer
It is very big, production cost is added, also has some moulds, is fixed, subtracted by structures such as bolts between head and cooler-shaper
The method contacted less is thermally shielded, although with certain effect, complicated, installation inconvenience, and work as bolt and produce
During stress variation, the bar quality of production can be destroyed.
Utility model content
The purpose of this utility model is to provide plastic rod extrusion die, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：Plastic rod extrusion die, including extruder

Middle part is provided with radiating groove, and the inner chamber of the plate-like adapter cavity is provided with vacuum heat-insulation cavity, the plate-like adapter cavity and head
Junction and the outside of canalis spinalis be installed with heat pad, the inner chamber of the cooler-shaper is provided with splitter box, institute
The both sides for stating splitter box are provided with discharge pipe, and the discharge pipe is interconnected with canalis spinalis, the cooler-shaper and disk
Circulating cooling chamber is provided with the inwall of shape adapter cavity, delivery port and water inlet are provided with the circulating cooling chamber.
Preferably, the plate-like adapter cavity is up and down installed with fastening bolt on two end faces.
Preferably, heat emission hole is offered on the outer wall of the heat pad.
Preferably, the discharge pipe is provided with four.
Compared with prior art, the beneficial effects of the utility model are：The plastic rod extrusion die is simple in construction, passes through
Transitional cavity is set, and vacuum heat-insulation chamber and heat pad are set, so greatly reduces extruder head to cooler-shaper
Heat transfer, equally serve heat-insulated effect.Meanwhile the installation maintenance of cooler-shaper is very convenient, it is not necessary to regulation folder
Screw is held, the bar caused by the creep of heat insulating washer is not concerned about and loses circle, eliminates the worry for frequently changing heat insulating washer, it is ensured that
Bar Forming Quality, reduces production cost, and production efficiency is also largely increased.
