Pressing mold

The present invention relates to a pressing mold, in particular to a venting hole provided on the stencil, which can separate the sound absorbing cotton after the cutting of the stencil from the stencil, so that the sound absorbing cotton does not adhere to the stencil.

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 through hole is to be cut in the sound absorbing cotton, the metal mold die having the shape of the through hole to be cut is provided on the metal mold base, and the metal cutter mold is heated and directly pressed onto the sound absorbing cotton. The through hole is cut in the sound absorbing cotton by forming the electric heat by the metal cutter mold, and the pressing portion of the outer edge of the cutter mold is further tightly pressed into the outer periphery 11 of the through hole 10 of the sound absorbing cotton 1 (as shown in the first figure). In this way, the through hole 10 of the sound absorbing cotton 1 can be cut; however, the conventional method for cutting the through hole 10 of the sound absorbing cotton 1 is to provide a metal die on a metal mold base. Therefore, the through hole 10 of the sound absorbing cotton 1 of different shapes is required to be made into a metal mold base and a die, and the metal mold base and the die are expensive to manufacture, and the overall weight is extremely heavy. Knowing that the sound absorbing cotton 1 after cutting through the hole 10, because the periphery 11 of the through hole 10 is only pressed at a high temperature, is easy The pressure of the raw hole 11 is not true, and the periphery 11 of the through hole 10 cannot be effectively and completely adhered tightly, so that the periphery 11 of the through hole 10 which is pressed and pressed is liable to be separated and cracked when used or subjected to vibration ( As shown in the second figure, the effect of sound absorption and noise reduction is reduced. In addition, the conventional metal cutter mold cuts the sound absorbing cotton 1 into the through hole 10, and the sound absorbing cotton 1 is cut due to the front side of the metal cutter mold. The sound absorbing cotton 1 adheres to the metal cutter mold, and the sound absorbing cotton 1 needs to be removed from the metal cutter mold by a tool or a hand, and is easily metal when the sound absorbing cotton is removed. The knife is burnt and is extremely dangerous to use.

The main purpose of the present invention is to provide a pressing mold for cutting through holes of sound absorbing cotton, which can effectively solve the defects caused by the metal cutting mold for cutting through holes of the sound absorbing cotton.

The pressing mold of the present invention comprises a template, at least one stamper, at least one die and at least one positioning module, wherein the template is made of wood, and the template is provided with at least one through hole, the through hole The hole is threaded through the template, the template is provided with at least one venting hole, and the stamper is disposed in the through hole of the template, and the stamper is composed of a plurality of metal sheets, and the side of the stamper is The die is protruded from the front surface of the template, and the die is disposed in the through hole of the template, and is disposed on the inner side of the die. The die is made of a metal material, and the outer side of the die The edge is provided with a blade edge protruding from the outer side of the die. The positioning module is also disposed in the through hole of the template and is disposed on the inner side of the die. The positioning module is made of wood. The positioning module has the same thickness as the template, and the positioning module and the die are positioned in the through hole of the template.

The pressing mold of the present invention, wherein the through hole of the template is formed in the same shape as the through hole of the cut sound absorbing cotton, and the shape of the die, the stamper and the positioning module disposed in the through hole are also The through hole of the cut sound absorbing cotton is set to be the same shape.

The advantage of the press mold of the present invention is that the sound absorbing cotton cut by the die can be separated from the template by the vent hole provided on the template, so that the sound absorbing cotton does not adhere to the template, and the template and the template The positioning module is made of wood, and it will not be burned when it is used, and its die can be pressed tightly around the through hole of the sound absorbing cotton to prevent separation of the perforation around the sound absorbing cotton. In the case of opening, it is more convenient and quick to cut the through hole of the sound absorbing cotton.

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 the details are as follows:
