Description

Sound absorbing cotton die structure

The present invention relates to a knife mold structure of sound absorbing cotton, in particular to a template made of wood material, wherein a metal stamper and a cutter are arranged on the template, and the stamper is provided with an auxiliary frame portion and a pressure. Hold the film, which can more closely press the material of the sound-absorbing cotton.

According to the general sound-absorbing cotton, it can be widely used in various interiors of vehicles (such as door panels, dashboards, etc.), home appliances, office electronic equipment, ships and buildings. The sound-absorbing cotton mainly has the function of sound absorption and noise reduction. If the sound absorbing cotton is to be cut into a specific shape, it is required to have a metal cutter die to be cut and formed on the metal mold base, and the metal cutter mold is heated and directly pressed onto the sound absorbing cotton by means of metal. The cutter mold forms electric heating to cut the sound absorbing cotton into the shape of the same shape as the cutter mold, and the pressing portion of the inner edge of the cutter mold further presses the periphery of the sound absorbing cotton into a compact body, so that the sound absorbing cotton 1 can be completed. Shape cutting; However, it is customary to cut and press the sound-absorbing cotton, because the periphery is only pressed with high temperature, it is easy to produce false presses, and the periphery can not be effectively and completely fully bonded, so it is used or In the case of vibration, the periphery of the press-fit is prone to separation and cracking, and the effect of sound absorption and noise reduction is reduced.

The purpose of this creation is to provide a mold structure for sound absorbing cotton, which can effectively solve the lack of the metal cutter mold of the conventional cut 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 through hole having the same shape as the cut sound absorbing cotton, and the through hole is provided with wood. a positioning module made of a material, a stamping system is sleeved on the positioning module and disposed in the through hole of the template, and all the cutters are sleeved on the outside of the stamper and disposed in the through hole of the template. The cutting blade is made of a metal material, and one side of the cutting blade is set as a flat surface, and the other side of the cutting blade is provided with a blade edge, and the blade edge is convexly disposed on the front surface of the template. One side of the mold and the cutter is flush with the back surface of the template, and the other side is convexly disposed on the front surface of the template, and the height of the mold is lower than the blade position of the cutter The stamper is composed of a plurality of laminated sheets made of a metal material, and the stamper is provided with a plurality of auxiliary frame portions, and the auxiliary frame portion is stacked with a plurality of metal materials. Hold the piece.

The utility model has the advantages that the mold structure of the sound absorbing cotton can greatly reduce the manufacturing cost of the die, and the auxiliary die part and the pressure holding piece are additionally provided on the stamper, which can surely achieve the cutting and more compact pressing. Sound-absorbing cotton makes it difficult to separate and achieve better sound absorption.

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, and the template 1 is made of a wooden material, and the template 1 is provided with the same shape as the cut sound-absorbing cotton. The through hole 10 is provided with a positioning module 11 made of a wooden material, and a stamper 2 is sleeved on the positioning module 11 and disposed in the through hole 10 of the template 1. The stamper 2 The embossing sheet 20 is made up of a plurality of metal sheets. The dies 2 are provided with a plurality of auxiliary frame portions 21, and a accommodating groove 22 is formed in the auxiliary frame portion 21, and the accommodating groove 22 is formed therein. The stacking is filled with a plurality of pressing pieces 23 made of a metal material, and all the knives 3 are sleeved on the outside of the stamper 2 and disposed in the through hole 10 of the template 1. The cutter 3 is made of metal material. One side of the cutter 3 is set as a flat surface, and the other side of the cutter 3 is provided with a blade edge 30, and one side of the stamper 2 and the cutter 3 is flat with the back surface of the template 1. The other side of the stamper 2 and the blade 30 of the cutter 3 are protruded from the front surface of the template 1 , and the height of the stamper 2 is lower than the blade edge 30 of the cutter 3 . Location, so Die is the structure of a sound-absorbing cotton.

When assembling, please refer to the first to fifth figures. First, the pressing pieces 20 of each piece of the stamper 2 are sleeved and stacked on each other, and the pressing pieces 23 of each piece are pushed and packed in each auxiliary frame. In the accommodating groove 22 of the portion 21, the stamper 2 is set on the positioning module 11, and the cutter 3 is sleeved on the outer peripheral surface of the stamper 2, so that the stamper 2 and One side of the cutter 3 is flush with the back surface of the positioning module 11 , and the other side of the stamper 2 and the blade 30 of the cutter 3 are protruded from the front surface of the positioning module 11 . The height of the stamper 2 is lower than the blade edge 30 of the cutter 3, and the set positioning module 11, the stamper 2 and the cutter 3 are forced into the through hole 10 of the template 1 at the same time. One end surface of the stamper 2 and the cutter 3 is flush with the back surface of the template 1, and the other end surface (the end surface having the blade edge 30) protrudes from the front surface of the template 1, so that the whole can be completed. Assembly.

When using, please refer to the fourth to sixth figures. When you want to cut and press the sound-absorbing cotton A, you only need to set the back of the template 1 on the electric machine table (not shown). The metal stamper 2 and the cutter 3 can be electrically transferred to the stamper 2 and the cutter 3 from the back end thereof, and the stamper 2 and the cutter 3 are electrically heated to form a high temperature, and then the stamper 2 is used. And the protruding end of the cutter 3 is pressed against the sound absorbing cotton A to be cut, and the sound absorbing cotton A is cut into a desired shape by the blade 30 of the cutter 3, and is set by the inner side of the cutter 3. The stamper 2 is pressed against the peripheral edge A1 of the sound absorbing cotton A, so that the periphery A1 of the sound absorbing cotton A is pressed by the plurality of pressing pieces 20 of the stamper 2 at a high temperature, and is pressed by the stamper 2 The auxiliary frame portion 21 and the pressing piece 23 are press-fitted into a molded bead, so that the peripheral portion A1 of the sound absorbing cotton A and the portion of the auxiliary frame portion 21 form an uneven indentation A2 (as shown in the sixth figure). By these tight indentations, the portion of the peripheral A1 that has been cut by the sound absorbing cotton A is firmly bonded without causing separation and cracking, thereby achieving a better sound absorbing effect; The template 1 is made of wood material, which can greatly reduce the manufacturing cost of the template 1, and the overall weight is light. The sound-absorbing cotton A is cut while being tightly pressed against the surrounding A1 material of the sound-absorbing cotton A, so that the sound-absorbing cotton A After cutting, the surrounding A1 is more flat and beautiful, which can greatly enhance the product value.

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.
