Background technology
Extrusion die is for completing extruding-out process, mainly using pressure by by the treated modeling such as hot melt
Material is squeezed between plug and mouth mold by tripper to be molded.In process of production, in order to ensure product quality, it is necessary to carry out aspiration and
Water cooling is operated, but conventional extrusion die is compared rearward due to aspiration point and water cooling point, specifically, at die cavity feed end 12mm
Water inlet, 22mm have air drain, and section bar needs to first pass through cooling, is then bonded cavity surface again, and surface smoothness is poor, and in order to
Ensure water cooling and aspiration effect, it is necessary to increase by a section mould, and this can undoubtedly increase cost, waste of materials.
The content of the invention
In view of the above-mentioned problems, being necessary to provide a kind of production product surface light, quality height, and save squeezing for cost of manufacture
Go out mould.
The technical solution adopted in the utility model：A kind of extrusion die, including a die ontology, a cover plate and a bottom plate,
The cover plate is arranged above the die ontology, and the bottom plate is arranged at below the die ontology, in the die ontology
Between offer a die cavity, offer multiple water channels, multiple water channels along the die cavity bearing of trend inside the die ontology
Set around the die cavity, and multiple described water channel one end, from being 7mm with a distance from the die cavity feed end, multiple water channels are equal
It is interconnected, the die ontology side and the cover plate side are provided with multiple water nozzles connected with the water channel, the mould
Tool body interior is additionally provided with multiple air drains, and multiple air drains set around the die cavity and connected with the die cavity, described
Air drain is 4mm from the minimum range of the die cavity feed end, and multiple air drains are interconnected via air flue, above the cover plate
The bottom panel side is provided with multiple valves connected with the air flue.
The beneficial effects of the utility model are：By increasing air drain at die cavity feed end 4mm, increase water inlet at 7mm,
Section bar can be caused to be bonded die cavity face as early as possible, cooled down as early as possible, so as to lift brightness；Meanwhile the elder generation of cooling and aspiration is exchanged
Order afterwards, first make section bar fitting die cavity face, then cooled down again, can be with further such that Surface of profile be bright；Finally, due to
Aspiration and cooling down operation in advance, enough aspirations and cool time can be ensured in existing die cavity, without being further added by addition
One section mould, has saved cost of manufacture.

Embodiment
The utility model is further described below in conjunction with accompanying drawing, illustrated embodiment is served only for explaining the utility model,
It is not intended to limit the scope of the utility model.
As Figure 1-Figure 5, it is a kind of extrusion die provided by the utility model, including a die ontology 1, a cover plate 2
With a bottom plate 3, the cover plate 2 is arranged at the top of die ontology 1, and the bottom plate 3 is arranged at the lower section of die ontology 1,
A die cavity 4 is offered among the die ontology 1, the cross sectional shape of the die cavity 4 can be decided according to the actual requirements.The mould
Multiple water channels 5 are offered along the bearing of trend of die cavity 4 inside body 1, multiple water channels 5 are set around the die cavity 4, with
The section bar for ensureing to enter in the die cavity 4 can by uniform water cooling, multiple described one end of water channel 5 from the feed end of die cavity 4 away from
From for 7mm, to cause section bar to cool down as early as possible, multiple water channels 5 are interconnected, the side of die ontology 1 and the cover plate 2
Side is provided with multiple water nozzles 6 connected with the water channel 5, and in the case where multiple water channels 5 are interconnected, cooling water can
Flowed out via the water nozzle 6 into the water channel 5 in the internal flow of die ontology 1, then via the other water nozzle 6,
So as to complete cooling water the water cooling to section bar is realized in the circulation of mould inside.It is additionally provided with inside the die ontology 1 multiple
Air drain 7, multiple air drains 7 set and connected with the die cavity 4 around the die cavity 4, and the air drain 7 enters from the die cavity 4
The minimum range for expecting end is 4mm so that the section bar for entering the die cavity 4 can be as early as possible by aspiration, so that it is bonded die cavity as early as possible
Face, multiple air drains 7 are interconnected via air flue 8, are achieved in insertion of the gas inside the die ontology 1, described
The top of cover plate 2 and the side of the bottom plate 3 are provided with multiple valves 9 connected with the air flue 8, the gas in the die cavity 4 according to
It is secondary to be pumped down to via the air drain 7, the air flue 8 and the valve 9 on the outside of mould, certain gas can be produced in the process
Stream, under the induced effect of the air-flow, can cause section bar to be faster bonded die cavity face.
In order to reduce the quantity of the valve 9 on the top of the cover plate 2 and the side of bottom plate 3, the cover plate 2 and described
Bottom plate 3 offers air chamber 10 respectively close to the side of the die ontology 1, and the air chamber 10 connects the valve 9 and the gas
Road 8, the gas come out from the air flue 8 uniformly enter in the air chamber 10, then via the valve 9 by the air chamber 10
Gas is taken away.
In order to improve the overall stability of mould, the lower section of bottom plate 3 is additionally provided with a pony sill 11.
The cover plate 2 is fixed on the upper surface of die ontology 1, and both are tightly connected, and the bottom plate 3 is fixed on described
The lower surface of die ontology 1, and both are tightly connected.The water nozzle 6 connects with the water channel 5 forms a circulating water channel, cooling
Water carries out recirculated water cooling through this passage.The valve 9, the air chamber 10, the air flue 8 and the air drain 7 are sequentially communicated to be formed
One bleed-off passage, the gas in the die cavity 4 are extracted out through this bleed-off passage.When using the extrusion die, section bar is via institute
The feed end for stating die cavity 4 enters, and advanced promoting the circulation of qi suction, i.e., be evacuated via the bleed-off passage at from the feed end 4mm
Processing so that section bar is bonded die cavity face as early as possible, and then, proceeds by water cooling at from the feed end 7mm, i.e., by described
Circulating water channel carries out recirculated water cooling, accelerates section bar to be cooled and shaped so that product surface is more bright.
The beneficial effects of the utility model are：By increasing air drain at die cavity feed end 4mm, increase water inlet at 7mm,
