优选的,所述木纹层是通过花纹辊在上表层上辊压出一道道凹凸槽纹路而形成的。
优选的,所述上表层为ABS/PVC或PVC膜中的一种,且上表层的厚度为0.5mm-2mm,加热温度为250℃-300℃。

优选的,所述发泡层含有质量百分比为5%-30%的玻璃纤维。
2、基于上述汽车内饰件,本发明还提供一种带有凹凸木纹的汽车内饰件的成型方法,所述该方法具体步骤如下:
S1、先将平整的上下表皮加热到软化点,并通过花纹辊在上表皮的表面辊压出一道道凹凸槽纹路,使得上表皮的上表面形成木纹层;
S2、再通过真空吸塑机将S1制得的上下表皮进行吸塑成型,以形成上表层和下表层;
S3、将S2制得的上表层和下表层进行裁切,修剪掉多余的边料;
S4、将S3中裁切后的上表层和下表层分别铺设于发泡模具的凹模内,并贴紧模具,同时在上表层搭接的背面和下表层搭接的正面粘贴表面密封层,以保证上表层和下表层搭接处的密封;
S5、将质量百分比为5%-30%的玻璃纤维和70%-95%的聚氨酯溶液加入搅拌机中进行混合,混合均匀后制得混合液;
S6、将S5制得的混合液浇注进凹模内部,而后进行合模保压,以进行发泡,制得发泡件;

与现有技术相比,本发明的有益效果是:
(1)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,有利于提高内饰件的生产效率,同时实现汽车内饰件的结构更加稳定,以便于内饰件的使用。
(2)基于本发明提供的成型方法能够实现汽车内饰件的双面用作外观面,使得汽车内饰件更加美观、实用。

1.一种带有凹凸木纹的汽车内饰件,其特征在于:包括发泡层(1),所述发泡层(1)的上表面粘接有上表层(3),且发泡层(1)的下表面粘接有下表层(2),同时所述上表层(3)的上表面还粘接有木纹层(4),所述发泡层(1)的顶端和底端均开设有沿水平方向等距离分布的凹槽(6),所述上表层(3)与下表层(2)的底端和顶端分别一体成型有与凹槽(6)相匹配的延伸块(5),且延伸块(5)插入凹槽(6)的内部。
2.根据权利要求1所述的一种带有凹凸木纹的汽车内饰件,其特征在于:所述木纹层(4)是通过花纹辊在上表层(3)上辊压出一道道凹凸槽纹路而形成的。
3.根据权利要求1所述的一种带有凹凸木纹的汽车内饰件,其特征在于:所述上表层(3)为ABS/PVC或PVC膜中的一种,且上表层(3)的厚度为0.5mm-2mm,加热温度为250℃-300℃。
4.根据权利要求1所述的一种带有凹凸木纹的汽车内饰件,其特征在于:所述下表层(2)为ABS/PVC或PVC膜中的一种,且下表层(2)的厚度为0.5mm-2mm,加热温度为150℃-200℃。
5.根据权利要求1所述的一种带有凹凸木纹的汽车内饰件,其特征在于:所述发泡层(1)含有质量百分比为5%-30%的玻璃纤维。
6.一种带有凹凸木纹的汽车内饰件的成型方法,适用于生产上述的汽车内饰件,其特征在于:所述该方法具体步骤如下:
S1、先将平整的上下表皮加热到软化点,并通过花纹辊在上表皮的表面辊压出一道道凹凸槽纹路,使得上表皮的上表面形成木纹层(4);
S2、再通过真空吸塑机将S1制得的上下表皮进行吸塑成型,以形成上表层(3)和下表层(2);
S3、将S2制得的上表层(3)和下表层(2)进行裁切,修剪掉多余的边料;
S4、将S3中裁切后的上表层(3)和下表层(2)分别铺设于发泡模具的凹模内,并贴紧模具,同时在上表层(3)搭接的背面和下表层(2)搭接的正面粘贴表面密封层,以保证上表层(3)和下表层(2)搭接处的密封;
S5、将质量百分比为5%-30%的玻璃纤维和70%-95%的聚氨酯溶液加入搅拌机中进行混合,混合均匀后制得混合液;
S6、将S5制得的混合液浇注进凹模内部,而后进行合模保压,以进行发泡,制得发泡件;
S7、将S6中发泡固化后的发泡件取出,并进行裁切,去除多余的边料,以得到带有凹凸槽纹路的汽车内饰件。
7.根据权利要求6所述的一种带有凹凸木纹的汽车内饰件的成型方法,其特征在于:所述S5中搅拌时间为20-60min,搅拌速度为1200-2000r/min。
8.根据权利要求6所述的一种带有凹凸木纹的汽车内饰件的成型方法,其特征在于:所述S6中保压时间为10-20分钟,且保压压力为2500-4000MPa。
