Description

Technical Field

[0001] The invention relates to the field of automobile interior trim panels, and in particular to a center console trim panel assembly and a production process thereof. Background Art

[0002] Most car center consoles will have a decorative panel located at the passenger seat. Some comfortable luxury cars will use wood materials, while some sports luxury models will use carbon fiber materials. Some inferior ones will use a plastic core with carbon fiber wrapped on the outside. Therefore, the interior design here is highly representative in car interiors. Ordinary family cars also often use the design style of luxury cars as a guide for interior design. However, due to cost constraints, the decorative panel usually uses a plastic shell plus a carbon fiber texture sticker, plastic water transfer printing, or directly embossing simulated carbon fiber texture on the plastic shell. The interior panels processed by these processes have very limited effects in imitating carbon fiber materials and have a strong sense of cheapness.

[0003] In summary, we propose a center console trim assembly with a plastic inner core and a dyed twill woven glass cloth outer layer and its production process to solve the above problems. Summary of the invention

[0022] S6. Conduct quality inspection on demoulding decorative panels and spray varnish on the surface of qualified decorative panels to further improve the surface brightness of the decorative panels.

[0023] The beneficial effects of the present invention are:

[0024] 1. The car center console decorative panel assembly uses cheap twill glass fiber cloth to replace carbon fiber cloth to decorate the decorative panel injection molded parts, so as to obtain a texture closer to the real carbon fiber decorative panel than the carbon fiber texture sticker and the carbon fiber texture embossed on the plastic shell, thereby improving the interior quality of the car center console under the condition of controllable cost.

[0025] 2. The car center console decorative panel uses a mold to press the twill glass cloth pre-impregnated with photosensitive glue with the injection molded part, and cuts off the excess part of the twill glass cloth during the pressing process. After the mold is opened, the finished product is obtained by light curing, which greatly improves the production efficiency compared to the manual pasting process.

[0026] 3. The process equipment for the car center console decorative panel has adjustable mold closing and mold opening damping. By adjusting the damping adjustment screw to control the intake and exhaust flow during the movement between the guide rod and the sleeve, the mold closing and mold opening speed can be controlled, making the mold closing and mold opening actions smooth, which is conducive to reducing product defects.

[0027] In summary, the automobile central control interior panel and production process effectively solve the problem of large differences in decorative effects between existing automobile central control imitation carbon fiber interior panels and carbon fiber decorative panels.
