The outer ring of fagging coats EVA foaming layer.
Moreover, each uniform intervals in support plate two sides in EVA foaming layer cladding are formed with a circle salient point, the salient point is penetrated
EVA foaming layer.
Moreover, the width of EVA foaming layer is 10~15mm, with a thickness of 5~8mm.
Moreover, bump height >=1mm, radius >=1mm.
Moreover, symmetrically making at four angles of the support plate of EVA foaming layer cladding, there are four location holes, in EVA foaming layer
Also there are four location holes for coaxial system.
Moreover, in support plate location hole aperture >=1mm, aperture >=2mm of location hole in EVA foaming layer.
Moreover, being respectively formed with a circle reinforcing rib on the inner edge of EVA foaming layer, the two sides of support plate.
Moreover, reinforcement height >=5mm, reinforcing rib width >=1.8mm.
Such L shape shape skeleton and high fillibility EVA foamed material are used in combination by injection molding, this filling material be applied to compared with
Big cavity structure and low cost, expansion ratio height.Cavity cross section leakproofness is high after expanding and can be with cavity steel for packing material
Plate is combined closely.Meanwhile such new shape can with steel plate brought close, be not easy in foaming process generate filler material displacement or
Person's obscission；And the existing vacancy of white vehicle can be used, installation is fixed, do not have to modify existing vehicle body sheet metal mold, greatly
Amplitude uses manpower and material resources sparingly, and conveniently solves bodywork cavity packing material in the case where not changing existing sheet metal mould
Also can achieve the purpose that install and use, the preparation of high filling-foam material by the way that resin and other raw mixtures are kneaded,
It squeezes out and is granulated, obtain the foamed material for body of a motor car cavity.Then pass through injection molding machine and framework material organic glass
(PMMA) injection molding is carried out.
The advantages of the utility model and the utility model has the advantages that
1, cavity filling member provided by the utility model carries out riveting using the existing hole location of vehicle body using riveting mounting structure
Installation is connect, without modifying to large-scale sheet metal mould, can significantly use manpower and material resources sparingly resource, have biggish market latent
Power.
2, the utility model skeleton structure is with fixed round salient point, salient point can make EVA foamed material preferably with bone
Frame, which is wanted to combine, increases that grab relay not easily to fall off.
3, the utility model skeleton and EVA have fixed circular shape concentric location hole, and concentric locating hole can be in quadric injection mould
In the process, make part is fixed not generate displacement in a mold, improve quadric injection mould qualification rate.
4, the utility model skeleton has a ring stiffener, and the reinforcing rib contraction that generates after skeleton injection molding that can contend with is answered
Power makes skeleton keep smooth and does not tilt；Another reinforcing rib is divided to customer segmentation to inside and outside two circle, and the subsidiary EVA material in outer ring has been enough
To the effect of filling cavity, therefore the purpose for saving foamed material is played without adding EVA foamed material in inner ring.
5, compound upper new construction in the utility model EVA foaming layer, easy for installation not easily to fall off, automobile cavity is passing through
After 20-30min, 150-210 DEG C of high-temperature bakings, EVA foaming layer is sticked on the inside of cavity on steel plate after being foamed, and is closely combined
Integrally, cavity passage barrier is effectively reached hermetically sealed, so as to improve the purpose of interior sound insulation vibration and noise reducing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the usage state diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, the embodiment
Only the utility model preferred embodiment, is not all of embodiment.
A kind of cavity filling member installed using the existing hole location of white body, including skeleton, EVA foaming layer 5, reinforcing rib
2, salient point 4 and location hole 1, the skeleton are made of support plate 3 and connecting plate 6, and support plate is vertically arranged, at the bottom of support plate
Portion integrally produces connecting plate, and support plate and connecting plate group are at L-shaped, and two connecting holes 7 are symmetrically formed on connecting plate, two connecting hole
Riveted with the existing hole location of white body, the support plate be it is rectangular, coat EVA foaming layer in the outer ring of support plate, EVA foaming layer
Width is 10mm, with a thickness of 6mm.It is formed with a circle salient point in each uniform intervals in support plate two sides of EVA cladding, the salient point penetrates
EVA foaming layer, salient point can make EVA foamed material preferably want to combine with skeleton, and relay is grabbed in increase, not easily to fall off.In EVA packet
Four angles of the support plate covered symmetrically are made there are four location hole, and also there are four location holes for coaxial system in EVA foaming layer, described fixed
Position hole can make part is fixed not generate displacement in a mold during quadric injection mould, improve quadric injection mould qualification rate.In EVA
The two sides of the inner rim supports plate of foaming layer is respectively formed with a circle reinforcing rib, and reinforcing rib can contend with the contraction generated after support plate injection molding
Stress makes support plate keep smooth and does not tilt, and in addition support plate is divided into inside and outside two circle, the EVA of outer ring cladding by the reinforcing rib
Material is enough to play the role of filling cavity, therefore plays the mesh for saving foamed material without coating EVA foamed material in inner ring
's.
For automobile cavity after 20-30min150-210 DEG C of high-temperature baking, EVA foaming layer is sticked to cavity after being foamed
On the steel plate of inside, be closely combined into one, cavity passage barrier effectively reached hermetically sealed, so as to improve it is interior every
The purpose of sound vibration and noise reducing.
The manufacturing method of the utility model are as follows: by being kneaded, being squeezed out by EVA resin and other raw mixtures, made
