Production process of automobile headrest

Abstract

The invention relates to production processes of automobile parts, in particular to a production process of an automobile headrest. The production process of the automobile headrest includes the following steps that firstly, a decorative outer cover of the automobile headrest is made of leather through turning according to the outline of a headrest core; secondly, the turned decorative outer cover is placed into a shaping cavity of an installation shaping mold, bent sections of headrest supporting rods are placed into the decorative outer cover, and the headrest supporting rods are positioned in the installation shaping mold; thirdly, an inflation device is used for inflating an inner cavity of the decorative outer cover, so that the decorative outer cover is bulged; fourthly, a spraying gun head of a foaming machine is connected with a material nozzle of the installation shaping mold, and the foaming machine fills foaming materials into the inner cavity of the decorative outer cover through the material nozzle until the decorative outer cover is full of the foaming material; fifthly, the whole decorative outer cover full of the foaming materials is shaped in the installation shaping mold for ten to thirty minutes; and sixthly, the installation shaping mold is opened, and the molded automobile headrest product is taken out. The production process of the automobile headrest has the advantages that the production process is simple, the production cost is low and product quality is easy to guarantee.

Description

technical field [0001] The invention relates to a production process of auto parts, in particular to a production process of an automobile headrest. Background technique [0002] The car headrest includes a decorative cover, a headrest strut and a foam headrest core. The usual production process is to position the headrest strut in the foam molding mold, fill the foam molding mold with foam material, and bring the foam into the foam molding mold. The foam headrest core with headrest struts is taken out of the shaping mold, the decorative cover is finished on the car, and then the decorative cover is put on the foam headrest core by the assembly jig to complete the production of the automotive headrest. The above-mentioned production process has the following defects: 1. Before filling the foam forming mold with foam material, it is necessary to apply wax to the inner wall of the foam forming mold and then fill it with foam material.

Problems solved by technology

The above-mentioned production process has the following defects: 1. Before filling the foam forming mold with foam material, it is necessary to apply wax to the inner wall of the foam forming mold and then fill it with foam material. The production process is complicated, the production efficiency is low, and the production cost is high; 2. The decorative outer cover needs to be designed and assembled outside the foam headrest core, which increases the production cost. The inner cavity of the decorative outer cover needs to be exactly the same as the shape of the foam headrest core to ensure that the decorative outer cover does not wrinkle, and the product quality is not easy to guarantee
