Abstract

The invention discloses a hot press molding process for automobile sound insulation foam. The hot press molding for the automobile sound insulation foam process comprises the following steps of designing the size of the foam based on purposes; preparing a foaming pore plate; processing and forming raw materials; cutting the formed foam according to design requirements to form finished foam; and collecting waste materials formed by cutting, and retreating the collected waste materials. The foaming pore plate is adopted for attraction, a polyester fiber plate is used for sound insulation, then cutting is conducted according to the specified shape after plate machining is completed, meanwhile, the size of the foam is designed in advance based on the product size, the generation of the waste materials is reduced, and finally the waste materials are recycled and re-machined, so that the utilization rate of the materials can be increased, and the problem that the production cost is increaseddue to the fact that an existing process generates more waste materials is solved.

Description

technical field

[0001] The invention relates to the technical field of foam processing, in particular to a heat-pressing forming process of sound-insulating foam for automobiles. Background technique

[0002] With the rapid development of social economy, the sound-absorbing device is also called sound-absorbing material or sound-absorbing sponge. High-quality auxiliary materials, sound-absorbing device materials made by high-temperature mixing and foaming.

[0003] Because the shape of the sound insulation foam of the car needs to be consistent with the parts that need to be bonded, it needs to be cut, and the cut waste will not be used in the vehicle factory, which will cause material waste and transportation waste, thereby increasing production costs. Contents of the invention

[0004] The object of the present invention is to provide a heat-pressing forming process of sound-insulating foam for automobiles, which aims to solve the problem that the existing process will ...
