Manufacturing process of automotive interiors

Abstract

The invention provides a manufacturing process of automotive interiors. The manufacturing process comprises the following steps: adsorbing diaphragms which are designed with different patterns in advance onto the surface of a mold cavity of an injection mold before mold closing, and then mixing and injecting plastics in a molten state, which are mainly PC+ABS materials, into a mold to ensure that the diaphragms and the plastics are fused into a whole; after the diaphragms are manufactured and molded, cutting the diaphragms, molding the diaphragms, trimming the diaphragms, preparing finished products, performing injection molding, and positioning the diaphragms; and then spraying a mold releasing agent onto the surface of a skin forming mold, then spraying in-mold paint, spraying the in-mold paint with different colors according to the product needs, then spraying a liquid-state PU raw material, controlling the thickness of the skin by virtue of a spraying mechanical arm, and finally cooling and stripping the mold, wherein based on different raw material formulas, the curing time is 40-180s. According to the manufacturing process of the automotive interiors, provided by the invention, uniform rigidity of a cover plate can be achieved, and early damages cannot be easily caused.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile interior decoration, belonging to the technical field of automobile parts manufacturing. Background technique [0002] The requirements for automotive interiors are generally relatively high, the surface quality requirements are high, the rigidity requirements are high, and the shape process is relatively complicated. When the top cover is stretched, due to the unevenness of its plastic deformation, the rigidity of a certain part will often be poor. When the poor cover plate vibrates, it is easy to produce a hollow sound. After the car has run a certain amount of distance, it is easy to produce a clanging sound, causing early damage to the cover plate and making the passengers very uncomfortable. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing process for automobile interior decoration, which can make the rigidity of the cover plate...
