Description

Sound-absorbing structure of sound-absorbing cotton

The present invention relates to a compression mold structure of a sound absorbing cotton, in particular to a template made of a wooden material, and a stamper composed of a metal ring-shaped stamper and a sheet-shaped stamper is provided on the template. The manufacturing cost of the stamper is reduced, and the material of the sound absorbing cotton can be firmly pressed.

According to the sound-absorbing cotton generally made of high-performance sound absorbing material, the sound-absorbing cotton can be widely used in vehicle interiors (such as in door panels, in dashboards, etc.), home appliances, office electronic equipment, ships and buildings, etc. In the industry, the sound-absorbing cotton mainly has the function of sound absorption and noise reduction. Because the sound-absorbing cotton is a multi-layered fluffy material, if it is not pressed and positioned at the appropriate part, the sound-absorbing cotton of each layer is easily separated, resulting in the effect of sound absorption and noise reduction. However, the conventional method for pressing the sound-absorbing cotton is to provide a metal stamper on a metal template, and the metal stamper is a block-shaped body, so that the pressure of the different shapes is pressed on the sound-absorbing cotton. In the joint part, a metal template and a block metal die of a desired shape are required, and the metal formwork is extremely expensive to manufacture, and the overall weight is extremely heavy, and the metal stamper is a block body. The pressed surface is formed into a flat surface, which is easy to produce a false press. Therefore, in the case of using or encountering vibration, the pressed portion is likely to be separated, and the effect of sound absorption and noise reduction is reduced.

The purpose of this creation is to provide a compression mold structure for sound absorbing cotton, which can effectively solve the shortcomings of the conventional sound absorbing cotton.

The die structure of the sound-absorbing cotton of the present invention is mainly provided with a template, which is made of a wooden material, and the template is provided with a plurality of through holes, and the through holes are provided with a plurality of annular stampers which are sleeved with each other. The ring-shaped stamper is made of a metal material, and the ring-shaped stamper is provided with a pair of joint grooves, and the mating grooves of the ring-shaped stampers are alternately arranged, and the innermost type of the ring-shaped stamper is provided with a plurality of a sheet-shaped stamper stacked on each other, the sheet-shaped stamper is stacked to form a columnar shape, and the sheet-shaped stamper is also made of a metal material, and the ring-shaped stamper and one end face of the sheet-shaped stamper are The back side of the template is flat and the other end face protrudes from the front side of the template.

The die structure of the sound-absorbing cotton of the present invention has the advantages that the manufacturing cost of the stamper can be greatly reduced, and the material of the sound-absorbing cotton can be tightly pressed, so that it is difficult to separate and achieve a better sound absorbing effect.

For the purpose of achieving the above-mentioned purpose and effect of the above-mentioned use, a preferred and feasible embodiment will be described, and as shown in the drawings, the details are as follows:

For the embodiment of the present invention, as shown in the first and second figures, a template 1 is mainly provided. The template 1 is made of a wooden material. The template 1 is provided with a plurality of through holes 10, and the through holes 10 are provided. The annular stamper 2 is sleeved by a metal material, and the ring stamper 2 is provided with a pair of joint grooves 20, and the mating grooves 20 of each of the ring-shaped stampers 2 are provided. In the innermost annular die 2, a plurality of sheet-like stampers 3 stacked one on another are disposed, and the sheet-shaped stampers 3 are stacked to form a columnar shape, and the sheet-shaped stamper 3 is also Made of metal material, it is a compression mold structure of sound-absorbing cotton.

When assembling, please refer to the first to third figures, firstly, the respective ring-shaped stampers 2 are sleeved together, and the mating grooves 20 of the respective ring-shaped stampers 2 are alternately arranged, and the docking groove 20 can make the The ring-shaped stamper 2 is in an elastically expanded or compressed state, and a plurality of sheet-like stampers 3 stacked one on another are placed in the innermost ring-shaped stamper 2, and the above-mentioned set of ring-shaped stampers 2 and The sheet-shaped stamper 3 is forced into the through-hole 10 of the template 1 so that one end surface of the ring-shaped stamper 2 and the sheet-shaped stamper 3 is flush with the back surface of the template 1, and the other end surface is convex. On the front surface of the template 1, the butt groove 20 provided by the ring-shaped stamper 2 is elastically expanded and supported in the through-hole 10 of the template 1, and the ring-shaped stamper 2 is resisted by the sheet-shaped stamper 3. The restriction allows the ring-shaped stamper 2 to be tightly placed in the through-hole 10 of the template 1 without detachment, so that the overall assembly can be completed.

When using, please refer to the fourth figure. When you want to press the sound-absorbing cotton A, you only need to set the back side of the template 1 on the electric machine table (not shown). The metal on the template 1 The ring-shaped stamper 2 and the sheet-shaped stamper 3 can be electrically conducted to the ring-shaped stamper 2 and the sheet-shaped stamper 3 by the back end thereof, and the ring-shaped stamper 2 and the sheet-shaped stamper 3 are electrically conductive. After the heating is formed to a high temperature, the convex ends of the ring-shaped stamper 2 and the sheet-shaped stamper 3 are pressed against the sound-absorbing cotton A to be pressed, and the sound-absorbing cotton A is subjected to the ring-shaped stamper 2 and the sheet-shaped stamper. 3 The high temperature is tightly pressed, so that the ring-shaped indentation and the strip-shaped indentation are formed on the sound absorbing cotton A, and by pressing the indentation, the pressed sound A is firmly bonded to the pressed portion without Separation and splitting will occur; the template 1 of this creation is made of wood material, which can greatly reduce the manufacturing cost of the template 1, and the overall weight is light, and the material of the sound-absorbing cotton A can be tightly pressed, making it difficult to separate. Better sound absorption.

In summary, the present invention has achieved the intended use and effect, and is more desirable and practical than the prior art. However, the above embodiments are only specifically described for the preferred embodiment of the present invention. This embodiment is not intended to limit the scope of the present invention, and all other equivalents and modifications may be included in the scope of the invention covered by the present invention.
