Method for producing automobile front-wall sound-insulating pad

Abstract

The invention relates to a method for producing an automobile front-wall sound-insulating pad, belonging to the technical field of automobile inner ornament processing. The method comprises the following production steps of: piling up a raw material on a loading worktable, and placing the raw material on a baking box network chain by using a material sucking mechanism; conveying the raw material into a baking box by using a rotary network chain conveyer, and performing baking softening on the raw material; paving the raw material subjected to the baking softening on a mould by using the rotary network chain conveyer, pressing the raw material by using an upper pressing frame of the mould, performing vacuumizing adsorption and cooling molding to obtain a semi-finished product; positioning the semi-finished product, and cutting the semi-finished product by using a water knife to obtain the needed front-wall sound-insulating pad; and boxing up and warehousing the front-wall sound-insulating pad after inspection. By using the method provided by the invention, the requirements on performance indexes such as sound insulation, environmental protection, lightweight and the like of a front-wall sound-insulating pad assembly are met, the weight of the front-wall sound-insulating pad is greatly reduced, and the requirement on an entire automobile lightweight design is met.

Description

technical field

[0001] The invention relates to a production method of an automobile front wall sound insulation pad, in particular to an automobile front wall sound insulation pad which is installed in the car front wall cockpit and has heat insulation and sound insulation functions, and belongs to the technical field of automobile interior trim processing . Background technique

[0002] The car front wall sound insulation pad is installed in the car front wall cockpit to play the role of heat insulation and sound insulation. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound insulation, low weight, strong heat insulation, and environmenta...
