In view of the deficiencies in the prior art, the utility model discloses a car cavity is with sealed exemplar of manual sound insulation, at new car trial-manufacturing stage, the car cavity that adopts this design is with sealed exemplar of manual sound insulation and is trying to fit, and the mould is being opened according to the exemplar after trying to fit is qualified, can effectively reduce the improper loss that causes of mould.
The utility model discloses a realize above-mentioned purpose, the technical scheme who adopts is: the utility model provides a car cavity is with sealed exemplar of manual sound insulation, includes foamed sheet and metal spike, its characterized in that: the bending metal plate is composed of an integrated vertical plate and an arc-surface flat plate, and a plurality of through holes I are formed in the surface of the arc-surface flat plate;
The shapes of the plane metal plate and the foaming sheet are the same as that of the cambered surface flat plate of the bent metal plate, a plurality of through holes II are formed in the plane metal plate surface, and a plurality of through holes III are formed in the foaming sheet surface;
The cambered surface flat plate of plane panel beating and curved panel beating corresponds the setting, is equipped with the foaming sheet between face panel beating and cambered surface flat plate, and several metal willow nail one end passes cambered surface flat plate through-hole I, foaming sheet through-hole III and II tight fits of plane panel beating through-hole respectively in proper order, and it is even as an organic whole with curved panel beating, plane panel beating and foaming sheet.
The utility model has the advantages that, in the new car trial-manufacturing stage, need not to open the mould, adopt the utility model relates to a sealed sample spare that gives sound insulation manually for the car cavity tries on clothes, and convenient adjustment is trying on clothes and is opening the mould according to the sample spare after qualified, has avoided prior art to open the mould earlier, in case the improper loss that causes of mould.
Adopt the utility model discloses can practice thrift the cost, can verify the sealed effect of sound insulation of product rapidly, use safe and reliable.

Detailed Description
the structure of the present invention will be further explained with reference to the accompanying drawings.
As shown in figures 1 to 4 of the drawings,
A manual sound insulation sealing sample piece for an automobile cavity comprises a foaming sheet 3, a metal rivet 4, a bent metal plate 1 and a plane metal plate 2.
The bent metal plate 1 is composed of an integrated vertical plate 1-1 and an arc-surface flat plate 1-2, and a plurality of through holes I1-3 are formed in the surface of the arc-surface flat plate 1-2.
The shape of the plane metal plate 2 and the shape of the foaming sheet 3 are the same as that of the cambered surface flat plate 1-2 of the bent metal plate 1, a plurality of through holes II 2-1 are arranged on the plane metal plate 2, and a plurality of through holes III 3-1 are arranged on the foaming sheet 3.
The plane metal plate 2 is arranged corresponding to the cambered surface flat plate 1-2 of the bent metal plate 1, a piece of foaming sheet 3 is filled between the plane metal plate 2 and the cambered surface flat plate 1-2, one end of a plurality of metal nails 4 respectively and sequentially penetrate through the through holes I1-3 of the cambered surface flat plate 1-2, the through holes III 3-1 of the foaming sheet 3 to be tightly matched with the through holes II 2-1 of the plane metal plate 2, and the bent metal plate 1, the plane metal plate 2 and the foaming sheet 3 are connected into a whole.
The bending metal plate 1 and the plane metal plate 2 are both steel plates or aluminum plates.
The foaming sheet 3 is a high-temperature expandable material formed by mixing a vinyl polymer or a copolymer with a foaming agent, a cross-linking agent, a filling agent and the like, can be formed into a sheet by die pressing, extrusion and other modes during processing, is cut into a required shape, and is provided with a plurality of through holes III 3-1, and the positions of the through holes III 3-1 are superposed with the through holes I1-3 of the bending metal plate 1 and the through holes II 2-1 of the plane metal plate 2.
the hole diameters of the through holes I1-3 of the cambered surface flat plate 1-2 and the through holes III 3-1 of the foaming sheet 3 are slightly larger than the diameter of the main body part of the metal spike 4, so that the metal spike 4 can conveniently penetrate through the through holes I1-3, and the hole diameters of the through holes II 2-1 of the plane metal plate 2 are slightly smaller than the diameter of the head part of the metal spike 4, so that the head part of the metal spike 4 can conveniently penetrate into the through holes II 2-1 to realize tight fit without falling off.
The overall appearance of the manual sound insulation sealing sample piece of the automobile cavity can be flexibly designed according to the shape and the size of the automobile cavity.
The use method comprises the steps of welding the sound insulation sealing sample piece and the automobile cavity metal plate into a whole through the bent metal plate 1 vertical plate 1-1, and then baking at high temperature in the automobile production process, wherein the foaming sheet 3 expands and foams to fully fill a certain cross section of the automobile cavity, so that the purposes of sound insulation and noise reduction are achieved by blocking the flow of high-speed airflow.
