Description

Sound-absorbing cotton knife mold (5)

This creation is about a sound-absorbing cotton knife mold (5), especially a kind of mold with ventilation holes on the template and the positioning template. So that the sound-absorbing cotton will not stick to the template and positioning template.

Press, general sound-absorbing cotton can be widely used in vehicle interiors (such as door panels, dashboards, etc.), home appliances, office electronic equipment, ships and construction and other industries. The sound-absorbing cotton mainly has the effect of sound absorption and noise reduction. , and if the sound-absorbing cotton is to be cut into a specific shape, a metal die to be cut and shaped must be installed on the metal die base, and the metal die is heated and directly pressed on the sound-absorbing cotton. The knife mold forms electric heat to cut the sound-absorbing cotton into the same shape as the knife mold, and the pressing part of the inner edge of the knife mold tightly presses the periphery 10 of the sound-absorbing cotton 1 into one (as shown in the first picture) , in this way, the shape of the sound-absorbing cotton 1 can be cut; however, the conventional sound-absorbing cotton 1 after cutting and pressing, because the periphery 10 is only pressed together at a high temperature, it is easy to produce poor pressing, and its surrounding 10 can not be fully and effectively adhered tightly, so in the case of use or vibration, the surrounding 10 that is pressed is prone to separation and cracking (as shown in the second picture), resulting in a reduction in the effect of sound absorption and noise reduction. In addition, when the conventional metal die cuts the sound-absorbing cotton 1, the sound-absorbing cotton 1 is in close contact with the sound-absorbing cotton after the sound-absorbing cotton 1 is cut, so the sound-absorbing cotton 1 will stick to the metal die. The sound-absorbing cotton 1 needs to be removed from the metal knife mold with tools or hands, and the sound-absorbing cotton is easily scalded by the metal knife mold when removing the sound-absorbing cotton, which is extremely dangerous in use.

The main purpose of this creation is to provide a knife mold for cutting the periphery of sound-absorbing cotton, which can effectively solve the defects caused by the conventional metal knife mold for cutting sound-absorbing cotton.

It is made of metal material, the blade is set in the same shape as the sound-absorbing cotton after cutting, the outer side of the blade is provided with a blade, the blade is protruding from the front of the template, and the die It is installed in the chamber of the template and on the inner side of the cutter. The compression mold is formed by stacking several metal sheets. The compression mold is also set in the same shape as the cut sound-absorbing cotton. The outer side of the die also protrudes from the front of the template, and is lower than the height of the blade of the cutter. On the inner side of the stamper, the positioning template is also set in the same shape as the cut sound-absorbing cotton, the thickness of the positioning template is the same as the thickness of the template, the positioning template and the stamping mold and the knife are tightly positioned The positioning template is provided with at least one ventilation hole in the chamber of the template.

The sound-absorbing cotton knife mold (5) of this creation has the advantages that: through the ventilation holes set on the template and the positioning template, the sound-absorbing cotton after cutting by the knife can be separated from the template and the positioning template, so that the sound-absorbing cotton can be separated from the template and the positioning template.
