Abstract

The utility model relates to a knife mold which is used for trimming through holes in sound absorption cotton. The knife mold is composed of a knife mold base, a cutting knife and a press mold, wherein the knife mold base is made of wood materials, and a containing groove which has the same shape with a through hole to be trimmed is arranged in the knife mold base; a convex rib is arranged in the containing groove, and the cutting knife is arranged in the containing groove of the knife mold base and is made of metal materials; a cutting groove is arranged in one side edge of the cutting knife, and the other side edge of the cutting knife is provided with a knife point; the knife point is convexly arranged on the front of the knife mold base, and the press mold is arranged in the containing groove of the knife mold base and is arranged at the outer side face of the cutting knife; the press mold is composed of a plurality of metal sheets; a cutting groove is also arranged in the one side edge of the press mold, and the other side edge of the press mold is convexly arranged on the front of the knife mold base; and the convex height of the press mold is lower than the knife point position of the cutting knife. Thus, the metal cutting knife and the press mold formed by stacking the metal sheets are arranged on the wooden knife mold base, the manufacture cost of the knife mold can be greatly reduced, and the peripheral material of the through hole in the sound absorption cotton can be really tightly pressed.

Description

Cutting die

Technical field

This creation is relevant for a kind of cutting die, refer in particular to a kind of knife-die seat made from wooden material, in this knife-die seat be provided with metal cutting knife and several pieces sheet metals the stacked pressing mold that forms, can significantly reduce the manufacturing cost of cutting die, can be convenient to cut on the acoustical cotton open-work, and can be really the tight open-work periphery material of pressing acoustical cotton.

Background technology

General with the made acoustical cotton of high performance sound-absorbing material, it is in-built (in door-plate that this acoustical cotton can be widely used in vehicle, in the instrument board etc.), household electrical appliances, office electronic apparatus, the different industries such as boats and ships and building, this acoustical cotton mainly has the effect of absorbing sound and lowering noise, if and want with acoustical cotton on cut when establishing open-work, be provided with the metal cutting die of the open-work shape of wanting to cut in the metal die holder, to directly be pressed on the acoustical cotton after the heating of metal cutting die, form electric heating and be able on acoustical cotton, cut by the metal cutting die and establish open-work, and can giving tight pressing with the periphery 11 of the open-work 10 of acoustical cotton 1, the press keeping section of cutting die outer rim is integrated (as shown in Figure 1), so, can finish the cutting of open-work 10 of acoustical cotton 1; So, the existing mode that is used for cutting the open-work 10 of acoustical cotton 1, must be provided with the metal cutting die with a metal die holder, must make metal die holder and a cutting die so want to cut the open-work 10 of difform acoustical cotton 1, and the manufacturing cost of its metal die holder and cutting die is high, and overall weight is extremely heavy, present the acoustical cotton 1 that cuts behind the open-work 10 again, because the periphery 11 of its open-work 10 only is integrated with high-temperature laminating, it is unreal easily to produce pressing, the periphery 11 of its open-work 10 can't be really effective complete close adhesion, so using or meeting in the situation of vibrations, its periphery 11 by pressing easily produces and separates the situation (as shown in Figure 2) of splitting, and causes the effect of absorbing sound and lowering noise to reduce; Edge this, this creator concentrates on studies, improves because the existing mode that cuts the silencing cotton open-work has disappearance described above, is initiated out this creation then.

Summary of the invention

The main purpose of this creation is to provide a kind of manufacturing cost that can significantly reduce knife-die seat, and can be really the tight cutting die of the material of the open-work periphery of pressing acoustical cotton.

The cutting die of this creation, be used for cutting the open-work on the acoustical cotton, it is established by knife-die seat, cutting knife and pressing mold form, wherein, this knife-die seat is made by wooden material, this knife-die seat is provided with the tank with the open-work shape similar shape of acoustical cotton, in this tank, be provided with fin, and this cutting knife is located in the tank of this knife-die seat, this cutting knife is made by metal material, one side of this cutting knife is provided with grooving corresponding to the fin position on this knife-die seat, another side of this cutting knife is provided with the knife edge, this knife edge is convexly set on the front of this knife-die seat, and this pressing mold is located in the tank of this knife-die seat, and is located at the lateral surface of this cutting knife, this pressing mold is comprised of several pieces sheet metals, one side of this pressing mold also is provided with grooving corresponding to the fin position on this knife-die seat, and another side of this pressing mold is convexly set on the front of this knife-die seat, and the height that this pressing mold is convexly equipped with is lower than the knife edge position of this cutting knife.

The cutting die of this creation, wherein, the back side that this cutting knife and this pressing mold are located at this knife-die seat is burnishing surface.

The cutting die of this creation, wherein, in the piecemeal stacked tank that is placed in this knife-die seat of the sheet metal of this pressing mold.

The knife-die seat 2 of this creation is made with wood materials, can significantly reduce the manufacturing cost of cutting die, and overall weight is light, can be carried out at simultaneously again and cut open-work 50 on the acoustical cotton 5 and heat and closely pressing in the periphery 51 of its open-work 50, the open-work 50 of acoustical cotton 5 is cut and pressing more convenient, fast, and open-work 50 peripheries 51 of acoustical cotton 5 give high-temperature laminating by the pressing mold 4 that several pieces sheet metals 40 form, its surface can form concavo-convex impression 52, can make open-work 50 peripheries 51 of acoustical cotton 5 be able to close adhesion, can be because not using or meet the anxiety that has separation to split in the situation of vibrations, edge after the open-work 50 of acoustical cotton 5 is cut is more smooth, attractive in appearance, but improving product is worth.
