Description
Technical field
The present invention is related with Polymer Processing technology, especially with regard to a kind of vacuum of Polymer Processing machinery
Shade assembly.
Background technology
In Polymer Processing technical field, to avoid mould inside residual air at high temperature for mould inside
Macromolecule raw material impact, therefore, when macromolecule raw material is poured, is noted in the mould room space of mold, need to ensure mould room sky
In air properly detached, be project to reach, in then having in the prior art in mold clamping and form complete mould
Behind the space of room, air in the space of mould room is detached by preset aspirating hole on mold, also has diameter that mold is made to be located at vacuum environment
In, because being short of the presence of air when making mold clamping, make the anxiety for being formed by noresidue air in the space of mould room, these technologies in
General common technology contents are belonged in Polymer Processing technical field.
Wherein, the vacuum pumping technology outside the known mould for making mold be located in vacuum environment, specific example is then just like China
Taken off in case before M316793 new patents, with the external air of cover body isolation, form independent space and it is available compared with
The low energy is detached space interior air, forms vacuum environment, meanwhile, it is further provided in case before the new patent
Under the vacuum state in space where ensuring mold, enable the crowded cylinder part being located in air that macromolecule raw material is injected mold
It is interior, with this, topping is carried out either under mold die opening state or carries out material feeding under mold clamping state, is avoided sky
Gas is mixed into the space of mould room, to ensure the quality of molded product.
But because the type of polymer shaping product is various, mold form, composition or size needed for molding etc. also more change
Change, and the combined structure that case is taken off before the new patent is only capable of that crowded cylinder part is allowed to stretch into cover body from the single specific position of cover body
In portion space so that the material hole position of mold must be consistent with the specific position, squeeze cylinder part and begin to be able to macromolecule original
Material is injected via material hole in the mould room space of mould inside, does not attain ideal yet using upper in industry.
Invention content
Therefore, the main object of the present invention is providing a kind of vacuum shade assembly of Polymer Processing machinery, can
In response to different molds, it is able to accurately connect with the material space that enters of mold using to export the crowded cylinder part of macromolecule fused raw material
It is logical, enable topping or material feeding operation smooth.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of vacuum shade assembly of Polymer Processing machinery, in one providing and the separate internal of atmospheric isolation is empty
Between hood, between the outlet to export macromolecule raw material, by the hood first perforation, be located at intermediary member
On part second perforation and on extremity piece third perforation to each other intersection connection is formed by channel, for outside to
The outlet of output molten state macromolecule raw material stretches through into the hood inner space, to carry out the processing journey of topping or material feeding
Sequence, accordingly, the medium element first can be worn in addition to being able to ensure the air-tightness between the channel and outside atmosphere by increasing this
The biperforate hole ranges of Kong Yu, it is being etc. that communicating position is selected within the scope of increased hole so that third perforation is able to, in response to
The feeding position of mold in the hood inner space changes, and is allowed to meet the demand in industry implementation.
For technology contents, the vacuum shade assembly of Polymer Processing machinery, including：
There is one hood a ringwall, an inner space to be located in the ringwall, and one first perforation is provided in the side of the ringwall
With wall, and it is connected to the inner space；One medium element is had an ontology, is airtightly amplexiformed in the ring with a first side
On wall, one second perforation is provided from the first side on the ontology, and is connected to first perforation；One extremity piece, by external force band
It is dynamic and can amplexiform in one and be moved between position and a disengaged position, there is one end body, with a side end face it is opposite with the ontology in this
One second side of one side corresponds in opposite directions, and third perforation is provided with the end, amplexiformed on position when the extremity piece is located at this
When, so that the end body is airtightly amplexiformed with a side end face and the second side, and third perforation is enabled to be connected to second perforation, but
When the extremity piece is located on the disengaged position, then make third perforation with the end body far from the medium element.
Wherein, which is able to the aperture of respectively greater than third perforation most with biperforate pore size maxima
Big value.
Further, first perforation and biperforate larger interior diameter must expand external macromolecule raw material supply
Outlet be able to stretch into the position range of the hood inner space, and the ontology and the ringwall can be further changed each other
The relative position amplexiformed, to change the intersection connected state between first perforation and second perforation, to make the medium element
It is able to smaller volume with the extremity piece, communicating position changes between allowing large range of hole, and composition is made more to simplify.
Specifically, which is in respectively elongated with biperforate hole shape, should to provide larger adjusting range
Third perforation is then able to that rounded or other are suitable for the hole shape that is concatenated with the outlet of external macromolecule raw material supply technology.
And for ease of amplexiforming and reducing volume between the medium element, the extremity piece and the hood, the ontology and the end can be made
Status is not plate-like, amplexiforms in opposite directions to each other and with side plate face.
In addition, amplexiforming tightness degree for ensure the extremity piece and the adjustment part, make the true of Polymer Processing machinery
Empty shade assembly further includes one with the engaging member for being combined with external crowded cylinder part；The engaging member has most supporting rods, respectively with
Bar axis one end is fixed in the end main body element, and a body is slidedly arranged on the shaft of most supporting rods, the first most elastomers, respectively
Between this body and the end body.
Further, which also includes two ennations, is symmetrically extended outward from the both sides of this body, two second
Elastomer is respectively interposed between the elongated end end of two ennations and the extremity piece, and two pilot pins are divided into the elongated end of those ennations
End simultaneously positions two second elastomers respectively.
