Abstract
The utility model relates to the field of automotive interior parts, and provides a non-woven felt sound insulation pad and a mold for manufacturing the non-woven felt sound insulation pad. The non-woven felt sound insulation pad comprises a base plate, a plurality of adsorption holes formed in the base plate, and fibers adsorbed in the adsorption holes, wherein the diameters of the adsorption holes are different, the distances between every two adjacent adsorption holes are different, and therefore different portions of the non-woven felt sound insulation pad have different natural frequencies. The non-woven felt sound insulation pad has a simple and reasonable structure, the different portions with the different thicknesses and the same density, and outstanding sound insulation, vibration isolation and anti-impact performance. In addition, the utility model further provides the mold for manufacturing the non-woven felt sound insulation pad.
Description
Technical field
The utility model relates to the automotive trim field, the die apparatus that relates in particular to a kind of automobile internal sound insulation pad and make this sound insulating pad.
Background technology
Vehicle noise insulation pad encloses positions such as driving cabin, main carpet before being installed in automobile, plays heat insulation and deadening.Being used for wrapping the vehicle drive cabin, reaching under the shockproof effect of sound-absorbing, also is the crucial interior trim that improves the comfort level in the car.Existing vehicle noise insulation pad is because the shortcoming of design, and soundproof effect not to be obviously catching up with people's requirement, and produces the complex process of preparation, the cost height, and product is important also big, is unfavorable for the developing direction of light energy-conservationization of car.
The utility model content
The purpose of this utility model provides that a kind of automobile of reasonable in design is non-to be spun the felt sound insulating pad and produce the non-mould that spins the felt sound insulating pad of above-mentioned automobile, solves one or more in the prior art problem.
According to an aspect of the present utility model, a kind of non-felt sound insulating pad of spinning is provided, comprise the substrate and the fiber that are provided with a plurality of adsorption holes, fiber is adsorbed in adsorption hole.
The utility model provides non-ly spins that felt sound insulating pad structure is simplified and rationally, be conducive to the energy-conservation developing direction of light car, and speed of production is fast, good in economic efficiency.
In some embodiments, the adsorption hole aperture is 2 to 8 millimeters, and the aperture of a plurality of adsorption holes is inconsistent.The inconsistent design in aperture can improve the non-soundproof effect that spins the felt sound insulating pad that the utility model provides greatly so that the non-felt sound insulating pad different parts that spins that the utility model provides possesses different natural frequencys.
In some embodiments, the pitch-row of adsorption hole is 4 to 10 millimeters, the inhomogeneous setting of the pitch-row of a plurality of adsorption holes.The inconsistent setting of pitch-row makes the non-felt sound insulating pad different parts that spins possess different natural frequencys equally, further improves the non-soundproof effect that spins the felt sound insulating pad.
According to another aspect of the present utility model, provide and made transfer mould and the corresponding forming die that shifts the mould setting that the above-mentioned non-mould that spins the felt sound insulating pad comprises that counterpart substrate arranges, shift mould and be provided with gas port.Transfer mould, forming die can be combined to form a cavity, and substrate card is combined in the cavity, and the gas port of forming die provides suction airflow, and pre-mixed fiber firmly is pumped to the adsorption hole surface, form the non-felt sound insulating pad of spinning.
In some embodiments, gas port is circular, and number is two.Make suction airflow have uniform suction force to adsorption hole on the substrate on the smooth and easy basis of assurance suction airflow passage.
Description of drawings
Fig. 1 is the non-structural representation that spins the felt sound insulating pad in the utility model one embodiment;
Fig. 2 is the structural representation of the utility model one embodiment transfer shifting formwork;
Fig. 3 is the structural representation of forming die in the utility model one embodiment.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
Fig. 1 has schematically shown the non-cross sectional drawing that spins the felt sound insulating pad according to a kind of embodiment of the present utility model.Comprise the substrate 1 that is provided with a plurality of adsorption holes 2 and the fiber 3 that is adsorbed in adsorption hole 2.Adsorption hole 2 apertures are 2 to 8 millimeters, the inconsistent setting in the aperture of a plurality of adsorption holes 2.The pitch-row of adsorption hole 2 is 4 to 10 millimeters, and a plurality of adsorption holes 2 are inhomogeneous layout.The utility model provides non-ly spins that felt sound insulating pad structure is simplified and rationally, meet the energy-conservation developing direction of light car, and speed of production is fast, good in economic efficiency.In addition, the aperture of adsorption hole 2, the inhomogeneous setting of pitch-row can make the non-felt sound insulating pad different parts that spins possess different natural frequencys, further improve the non-sound insulation of spinning the felt sound insulating pad, vibration damping, effect such as attractive in appearance.
Shown in Fig. 2 to 3, another aspect of the present utility model provides makes the above-mentioned non-mould that spins the felt sound insulating pad.Comprise transfer mould 10 and the corresponding forming die 11 that shifts mould 10 settings that counterpart substrate 1 arranges, shift mould 10 and be provided with gas port 12.Gas port 12 is circular, and number is two.Transfer mould, forming die can be combined to form a cavity, and substrate 1 can be fastened in the cavity.
The gas port 12 of general transfer membrane 10 is circular, and number is two.Make suction airflow have uniform suction force to adsorption hole on the substrate on the smooth and easy basis of assurance suction airflow passage.
The general mesh plate that has different apertures after the panel beating processing that adopts is as substrate 1, and through being cold worked into the shape that needs, the mould that re-uses supporting manufacturing utilizes the suction force of air-flow, and fiber is pumped on the substrate firmly, forms the non-felt sound insulating pad of spinning again.
More than statement only is optimal way of the present utility model; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these also should be considered as within the protection domain of the present utility model.
