Description

The vacuum shade assembly of Polymer Processing machinery

Technical field

The utility model is relevant with Polymer Processing technology, especially with regard to a kind of Polymer Processing machinery Vacuum 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 pouring, being noted in the mould room space of mould by macromolecule raw material, need to ensure that mould room is empty In air properly detached, be project to reach, in then having in the prior art in mould matched moulds and form complete mould Behind the space of room, air in the space of mould room is detached by default aspirating hole on mould, also has footpath mould is located at vacuum environment In, because being short of the presence of air when making mould matched moulds, make the anxiety of noresidue air in formed mould room space, these technologies in The technology contents typically commonly used are belonged in Polymer Processing technical field.

Wherein, the vacuum pumping technology outside the known mould for making mould be located in vacuum environment, its specific example is then just like China Taken off before M316793 new patents in case, it completely cuts off outside air with cover body, form independent space and it is available compared with The low energy is detached interior volume air, forms vacuum environment, meanwhile, further provided in case before the new patent Under the vacuum state in space where ensuring mould, enable the crowded barrier part being located in air that macromolecule raw material is injected into mould It is interior, with this, topping is either carried out under mould die opening state or material feeding is carried out under mould matched moulds state, sky is avoided Gas is mixed into the space of mould room, to ensure the quality of products formed.

But because the species of polymer shaping product is various, it is moulded, and required mould form, composition or size etc. also more change Change, and the combined structure that case is taken off before the new patent is only capable of allowing that squeeze barrier part stretches into cover body from the single ad-hoc location of cover body In portion space so that the material hole position of mould must be consistent with the ad-hoc location, squeeze barrier part and begin to be able to macromolecule original Expect to inject via material hole in the mould room space of mould inside, do not attain ideal yet using upper in industry.

Utility model content

Therefore, main purpose of the present utility model is to provide a kind of vacuum shade assembly of Polymer Processing machinery, It can be able to enter material space exactly with mould in response to different moulds using to export the crowded barrier part of macromolecule fused raw material Connection, makes topping or material feeding operation smooth.

To reach above-mentioned purpose, the utility model uses following technical scheme：

A kind of vacuum shade assembly of Polymer Processing machinery, in one to provide the separate internal sky with atmospheric isolation Between hood, between the outlet to export macromolecule raw material, by the hood first perforation, positioned at intermediary member The formed passage of the common factor connection of the second perforation on part and the 3rd perforation on extremity piece to each other, is used to for outside 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 passage and outside atmosphere by increasing this The biperforate hole scopes of Kong Yu, enable the 3rd perforation in the range of the hole of increases such as being select communicating position, with response to The pan feeding change in location of mould in the hood inner space, is allowed to meet the demand in industry implementation.

For technology contents, the vacuum shade assembly of Polymer Processing machinery, including：

One hood, with a ringwall, an inner space is located in the ringwall, and one first perforation is provided in the side of the ringwall With wall, and connected with the inner space；One medium element, with a body, is airtightly amplexiformed in the ring with a first side On wall, one second perforation is provided on the body from the first side, and is connected with first perforation；One extremity piece, by external force band It is dynamic and can amplexiform and be moved between position and a separation point position in one, with one end body, with a side end face it is opposite with the body in this One second side of one side is corresponded in opposite directions, one the 3rd perforation, is provided with the end, when the extremity piece is amplexiformed on position positioned at this When, the end body is airtightly amplexiformed with the second side with a side end face, and make the 3rd perforation be connected with second perforation, but When the extremity piece is located on the separation point position, then make the 3rd perforation with the end body away from the medium element.

Wherein, first perforation is able to the aperture of the respectively greater than the 3rd perforation most with biperforate pore size maxima Big value.

Further, first perforation and biperforate larger interior diameter, must expand outside macromolecule raw material supply Outlet be able to stretch into the position range of the hood inner space, it simultaneously can further change the body with the ringwall each other The relative position amplexiformed, to change the common factor connected state between first perforation and second perforation, so that the medium element Less volume is able to the extremity piece, communicating position changes between allowing large range of hole, composition is more simplified.

Specifically, first perforation, to provide larger adjusting range, is somebody's turn to do with biperforate hole shape respectively in elongated 3rd perforation be then able to it is rounded or other be suitable to the hole shape that is concatenated with the outlet of outside macromolecule raw material supply technology.

And for ease of amplexiforming between the medium element, the extremity piece and the hood and volume is reduced, the body 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 also includes one with for the engaging member combined with outside crowded barrier part；The engaging member has most support bars, respectively with Bar axle one end is fixed on the end main body element, a body, the shaft for being slidedly arranged on most support bars, the first most elastomers, respectively Between this body and the end body.

Further, the engaging member also includes two ennations, symmetrically extends outward from the both sides of this body, two second Elastomer is respectively interposed between the elongated end of two ennations end and the extremity piece, and two pilot pins are divided into the elongated end of those ennations End simultaneously positions two second elastomers respectively.
