Abstract
The utility model discloses a mold for achieving an ideal product density by formation using air kinetic energy. The mold comprises a mold body, on which a plurality of absorption holes are distributed irregularly. Under the action of the air kinetic energy, floe fibers are absorbed by the absorption holes on the mold body; and due to different mesh distribution densities, the flow fibers have different grouped thicknesses, and the finished product has different whole thicknesses but has the same whole density, so that the same whole sound insulation effect is achieved.
Description
Technical field
The utility model relates to mould applications, is meant that specifically raw material is fibroflocculent, has the mould of the automotive upholstery of soundproof effect in order to moulding.
Background technology
Conventional sound insulation is carried out mold pressing with automotive upholstery through the certain material plate of thickness and is realized; In mold process; The material plate of equal thickness is pressed into the product that different-thickness has definite shape, and the place of the different-thickness of shaped article has different density at this moment, and the difference of density can cause the difference of soundproof effect; Can't reach desirable sound insulation density, low density place has been exactly the soundproof effect difference.
The utility model content
The purpose of the utility model is to provide a kind of aerodynamic energy that utilizes to carry out moulding to reach the mould of ideal product density, utilizes wadding fibrous raw material, reaches the structure that shaped article has the different-thickness equal densities, with the soundproof effect of realizing.
Above-mentioned purpose realizes through following technical scheme:
Utilize aerodynamic energy to carry out moulding to reach the mould of ideal product density, include die ontology, it is characterized in that: die ontology is provided with a plurality of adsorption holes, and a plurality of adsorption holes are irregular distribution.
Adopt the mould of said structure; Enter in the mould when wadding fibrous, when vacuumizing state, under the effect of aerodynamic energy; Wadding fibrously held by the adsorption hole on the die ontology, the density difference that mesh distributes makes that the wadding fibrous thickness that gathers is different.In general, mesh distributes and dredges wadding fibrous held few of some, and product thickness is thinner; Wadding fibrous held more that the mesh distribution is closeer, product thickness is thicker, and the different but whole density of the integral thickness of last shaped article is the same, reaches identical whole soundproof effect.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in 2, utilize aerodynamic energy to carry out moulding to reach the mould of ideal product density, include die ontology 1, die ontology 1 is provided with a plurality of adsorption holes 2 that have, a plurality of adsorption hole 2 irregular being distributed on the die ontology 1.
Adopt the mould of said structure; Enter in the mould when wadding fibrous, when vacuumizing state, under the effect of aerodynamic energy; Wadding fibrously held by the adsorption hole on the die ontology 12, the density difference that mesh distributes makes that the wadding fibrous number that gathers is different.In general, mesh distributes and dredges wadding fibrous held few of some, and product thickness is thinner; Wadding fibrous held more that the mesh distribution is closeer, product thickness is thicker, and the different but whole density of the integral thickness of last shaped article is the same, reaches identical whole soundproof effect.
The above; It only is the preferred embodiments of the utility model; Be not that the utility model is done any pro forma restriction; Every know-why according to the utility model still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations or modification that above embodiment did.
