In a method for producing a component (500) from translucent plastic (50), which component has a front face containing n profiles (51), in particular n protruding profiles, and a rear face covered with a colored film (40), first, an injection mold (100) is provided, which comprises a first mold part (10) and a second mold part (20), which together enclose a cavity (30) having a profile of the component (500) to be produced when the mold is closed. The surface of the first mould part (10) is a die for the front face of the component (500) and has n structures (11), in particular n recesses, corresponding to n contours (51) of the component. And the surface of the second die part (20) is a concave die on the back surface of the component (500). The film (40) is positioned on a surface of the second mold part (20). The injection mold (100) is closed, and a plasticized plastic material (50) is injected into the cavity (30) formed. After the plasticized plastic (50) has cured, the component (500) provided with the film (40) is demoulded. In the method, a surface of the second tool part (20) is provided with n projections (21), and the film (40) is provided with n recesses (43) prior to positioning in such a way that the n projections (21) on the surface of the second tool part (20) snap into the n recesses (43) of the film when positioning the film (40).
在用半透明塑料(50)制造部件(500)的方法中,所述部件具有包含n个轮廓(51),特别是n个突出轮廓的正面,和用有色薄膜(40)覆盖的背面,首先,提供注模(100),其包括第一模具部(10)和第二模具部(20),当模具闭合时,所述模具部共同围成具有所述待制造部件(500)的轮廓的空腔(30)。所述第一模具部(10)的表面为所述部件(500)的正面的凹模,且具有对应于所述部件的n个轮廓(51)的n个结构(11),特别是n个凹部。所述第二模具部(20)的表面为所述部件(500)的背面的凹模。将所述薄膜(40)定位在所述第二模具部(20)的表面上。将所述注模(100)闭合,并且将塑化的塑料(50)注入所形成的所述空腔(30)。在所述塑化塑料(50)固化后,将配设有所述薄膜(40)的部件(500)脱模。在所述方法中,为所述第二工具部(20)的表面提供n个突起(21),且在定位之前以某种方式为所述薄膜(40)配设n个凹口(43),使得在定位所述薄膜(40)时,所述第二工具部(20)的表面上的n个突起(21)卡入所述薄膜的n个凹口(43)。
