Abstract
It the utility model is related to polyurethane decompression foaming technical field, concretely it is a kind of V-type hard sealing structure for polyurethane decompression foaming, cabinet foam by left plate, right plate, top plate, bottom plate, front and rear panels form, left plate below right plate with being equipped with recessed module, recessed module is positioned at a left side, between right plate and bottom plate, the lower section of foreboard and back plate is provided with protrusion module, bossing and the recess of recessed module for protruding module are mutually chimeric, the back of protrusion module then fits with bottom plate, the utility model seals using relatively hard material, in order to reduce leakage rate, so it is not that plane directly contacts in sealing, but use v-shaped structure, so effectively reduce the flow velocity of gas, realize subnormal ambient.
Description
Technical field
Polyurethane decompression foaming technical field is the utility model is related to, is concretely that one kind is used for polyurethane decompression foaming
V-type hard sealing structure.
Background technology
Polyurethane foam is that polyalcohol and isocyanates course of reaction middle-molecular-weihydroxyethyl continue to increase, in simultaneous reactions liquid phase not
The angry bubble of stopping pregnancy, forms foam.Continue to increase, bubble is constantly produced in simultaneous reactions liquid phase, form foam.Foaming agent is to prepare
The essential raw material of hard polyurethane foams, it is typically a kind of lower boiling liquid compound.Caused by foaming process
Heat vaporizes foaming agent, produces gas core and increases, bubble is wrapped to form by polyurethane reaction thing.
Decompression foaming is：Casing an equipment controlled less than being foamed in normal pressure certain value.Foam environment
Air pressure it is relatively low when, foaming agent be easier from reaction liquid phase in escape, formed gas core.When air pressure is lower, gas karyogenesis it is faster,
Expanding foam solution expansion is rapider, and the mobility for showing as foam is higher, distributivity is better.When reacting quickly, gas core, which increases, to be exceedingly fast,
Abscess is minimum.Foam aperture and structure can so be greatly improved.
So decompression foaming technology is to create a closed space at all, and produces one with vavuum pump and bear
The environment of pressure, then casing foamed inside it.Foaming terminates, and opens this closed space, takes out product.
The good Novel hard-seal structure for designing a kind of sealing property in polyurethane decompression foaming device for this is very
Important.
The content of the invention
The utility model breaks through the problem of prior art, devises a kind of good Novel hard-seal structure of sealing property.
In order to achieve the above object, the utility model devises a kind of V-type for polyurethane decompression foaming and seals knot firmly
Structure, including foaming cabinet, it is characterised in that：Foaming cabinet is made up of left plate, right plate, top plate, bottom plate, front and rear panels,
Be equipped with recessed module below left plate and right plate, recessed module between left and right side plate and bottom plate, foreboard and back plate
Lower section is provided with protrusion module, and it is mutually chimeric to protrude bossing and the recess of recessed module of module, protrudes the back of the body of module
Portion then fits with bottom plate.
The recess of the recessed module is shaped as " V " type.
The utility model compared with prior art, seals using relatively hard material, in order to reduce leakage rate,
So not being that plane directly contacts in sealing, but v-shaped structure is used, so effectively reduce the flow velocity of gas, realized negative
Pressure ring border.
Brief description of the drawings
Fig. 1 is the structural representation of cabinet in the utility model.
Fig. 2 is the sectional view of cabinet in the utility model.
Fig. 3 is enlarged drawing of the present utility model.
Referring to Fig. 1,1 is top plate, and 2 be left plate, and 3 be foreboard, and 4 be back plate, and 5 be right plate, and 6 be bottom plate, and 7 be recessed mould
Block, 8 be protrusion module.
Embodiment
The utility model is described further with reference to accompanying drawing.
Referring to Fig. 1, the utility model devises a kind of V-type hard sealing structure for polyurethane decompression foaming, including hair
Cabinet is steeped, foaming cabinet is made up of left plate 2, right plate 5, top plate 1, bottom plate 6, foreboard 3 and back plate 4, left plate 2 and right plate
5 lower sections are equipped with recessed module 7, and between left and right side plate and bottom plate 6, foreboard 3 and the lower section of back plate 4 are provided with recessed module 7
Module 8 is protruded, the bossing and the recess of recessed module 7 of protrusion module 8 are mutually chimeric, protrude the back of module 8 then
Fitted with bottom plate 6.
What the utility model concave entered the recess of module 7 is shaped as " V " type.
In specific implementation, the utility model seals using relatively hard material, in order to reduce leakage rate, institute
Not to be that plane directly contacts in sealing, but v-shaped structure is used, so effectively reduce the flow velocity of gas, realize negative pressure
Environment.
Claims (2)
