Embodiment Construction

[0021] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0022] Such as figure 1 with 2 As shown, a cutting mold for sound-absorbing cotton includes a fixed plate 2, a knife 1 fixed on the fixed plate 2, and an upper plate surface 3 that is located above the knife and can move up and down. The knife 1 surrounds the fixed plate 2 Become the shape that sound-absorbing cotton 4 needs to be processed into.

[0023] One end of the cutter 1 has a blade 11, so the end of the cutter 1 away from the blade 11 is fixed on the fixed plate 2, the slant angle of the blade 11 exceeds 45°, the larger the slant angle, the sharper the cutter 1, and the cut out The smaller the probability of sound-absorbing cotton bursting, the better the edge sealing effect.

Abstract

Disclosed is a cutting die for sound absorption cotton. The cutting die comprises a fixing plate, a cutter and an upper plate surface, wherein the cutter is fixed to the fixing plate, and the upper plate surface is located above the cutter and can move up and down. The shape, needing to be processed, of the sound absorption cotton is defined by the cutter on the fixing plate. The cutting die has the advantages that the number of bursting edges is small, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of sound-absorbing cotton cutting, and in particular relates to a cutting mold and a cutting method for sound-absorbing cotton. Background technique [0002] The production and forming of sound-absorbing cotton is currently on the market mainly by laser cutting to achieve the desired shape. The advantage of laser cutting is that the sample production speed is fast and the technical difficulty is low. The disadvantage is that the efficiency is low during mass production, and the cut surface of the product cannot be cracked to achieve the edge banding effect, and the internal materials of the product will be scattered. Contents of the invention [0003] The main purpose of the present invention is to provide a cutting mold and cutting method for sound-absorbing cotton, which are used to solve the above problems, so as to improve the cutting efficiency of sound-absorbing cotton and improve the cutting effect. [0004...
