Automotive interior trim basting stitch process

Abstract

The invention discloses an automotive interior trim basting stitch process, and relates to automotive interior trim piece processing process mainly in order to solve the problems of high cost and lowspeed of an existing basting stitch process. Firstly, a flame robot is used to extract the oil of a framework, after the degreasing treatment is completed, the surface of the framework is sprayed withtwo parts of glue by using glue spraying equipment, an electric cast die is installed on a hot pressing molding machine, the glue-sprayed interior trim plate framework is placed on a convex die of the hot pressing molding machine, the skin of the framework is placed on a heating plate of the hot pressing molding machine to be heated, the heating temperature is 190-210 DEG C, the heated skin is moved into a concave die, leather pattern and stitch pattern are formed in the concave die, the heated skin is pre-molded through the vacuum force effect of upper and lower die fitting, the pattern andstitch pattern are printed on the skin, and the skin meets the shape; and then the skin and the interior trim plate framework are compounded together, a product is obtained after molding is completed,the excess process edge of the skin after molding is cut off, and the automotive interior trim basting stitch process has the advantages of being low in cost and high in processing speed.

Description

Technical field: [0001] The invention relates to a processing technology for automobile interior parts, in particular to a process in which the skin of the right decorative panel of an automobile instrument panel is formed in a mold and then directly laminated on a base material without subsequent processing of the skin. Background technique: [0002] Originally, the interior false suture is to first vacuum-form the skin (without back foam), and then bond the skin and the base material together through a foaming process. The disadvantage is that the processing cost is high, the speed is slow, and the quality is poor. Invention content: [0003] The technical problem to be solved by the present invention is to provide a false stitching process for automobile interior decoration with low processing cost and high speed. [0004] The above purpose is achieved as follows: first, the flame robot is used to extract the grease of the skeleton, and after the degreasing treatment is...

AI Technical Summary

Problems solved by technology

[0002] It turns out that the false stitching of the interior is to vacuum form the skin (without back foam) first, and then bond the skin and the base material together through a foaming process. The disadvantages are high processing cost, slow speed, and poor quality.
