The invention discloses an automobile interior trim part with concave-convex wood grains and a forming method thereof, which relates to the technical field of automobile part production. The automobile interior trim part comprises a foamed layer, an upper surface layer is adhered to the upper surface of the foaming layer; a lower surface layer is adhered to the lower surface of the foaming layer;meanwhile, a wood grain layer is adhered to the upper surface of the upper surface layer; grooves which are distributed at equal intervals in the horizontal direction are formed in the top end and thebottom end of the foaming layer; extending blocks matched with the grooves are integrally formed at the bottom ends and the top ends of the upper surface layer and the lower surface layer respectively; according to the automobile interior trim part provided by the invention, the extension blocks are integrally formed on the lap joint surfaces of the upper surface layer, the lower surface layer and the foaming layer; the extension blocks are embedded into the foaming layer, so that lap joint between the upper surface layer, the lower surface layer and the foaming layer is firmer, the problem that dislocation occurs when the upper surface layer, the lower surface layer and the foaming layer are in lap joint is effectively avoided, the structure of the automobile interior trim part is more stable, and use of the interior trim part is facilitated.
本发明公开了一种带有凹凸木纹的汽车内饰件及其成型方法,涉及汽车零部件生产技术领域,该带有凹凸木纹的汽车内饰件,包括发泡层,所述发泡层的上表面粘接有上表层,且发泡层的下表面粘接有下表层,同时所述上表层的上表面还粘接有木纹层,所述发泡层的顶端和底端均开设有沿水平方向等距离分布的凹槽,所述上表层与下表层的底端和顶端分别一体成型有与凹槽相匹配的延伸块,本发明提供的汽车内饰件通过在上下表层与发泡层的搭接面上一体成型的延伸块,延伸块嵌入发泡层,从而实现上下表层与发泡层之间搭接更加牢固,有效的避免了上下表层与发泡层搭接时发生错位的问题,实现汽车内饰件的结构更加稳定,以便于内饰件的使用。
