Problems solved by technology

In the existing production process of sound insulation pads, the phenomenon of delamination at the edge of the product often occurs, which not only affects the appearance, but also has a certain impact on the functionality, which increases the repair time, and will directly cause the product to be scrapped and increase the production man-hour. and cost
At present, the above-mentioned delamination problem is improved by extending the holding time, which does not solve the fundamental problem and affects production efficiency

Embodiment Construction

[0019] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0020] see figure 1 As shown, this preferred embodiment provides a method for improving the edge delamination of a sound insulation pad, comprising the following steps:

[0021] (1) Design the mold and set the working parameters. The mold in step (1) is in the form of a hot mold and a cold material. The upper and lower molds of the mold are respectively set to a target temperature of 180 ° C, and a plurality of temperature measurement areas are set in the upper and lower molds, generally 4 or 6, and according to the actual measured temperature. The temperature of each temperature measurement area is regulated. After the temperature test is completed, the mold gap is measured, and the aluminum foil paper of about 100mm×100mm is used to roll it into a ball with a diameter of 10-15mm and place it at the mark of t...

Abstract

The invention discloses a method for improving edge layering of a sound insulation pad, which comprises the following steps: (1) designing a mold, and setting working parameters; (2) selecting a sound insulation pad material, and combining and laying the sound insulation pad material; (3) putting the laid material into a mold for compression molding; and (4) pressing the edge of the sound insulation pad to realize stepped closing. According to the method, an existing edge pressing process is optimized, different edge pressing forms are designed, and the edge of the sound insulation pad forms the stepped closing-up, so that the problem that the edge is prone to layering is effectively solved, the forming quality is high, the pressure maintaining time can be properly shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile sound insulation pad manufacturing, in particular to a method for improving the edge delamination of the sound insulation pad. Background technique [0002] With the rapid development of the world economy, the continuous improvement of people's living standards, and the rapid development of the automobile industry, people's requirements for automobiles are not only beautiful in appearance, but also in the comfort, functionality and noise resistance of interior decoration. high demands. In the existing production process of sound insulation pads, the phenomenon of product edge delamination often occurs, which not only affects the appearance, but also has a certain impact on the functionality, and increases the repair time. and cost. At present, the above-mentioned delamination problem is improved by prolonging the holding time, which does not solve the fundamental problem and affects the produ...
