    • The invention relates to a method and a device for producing a toothbrush (50) or part thereof by the two-component or multi-component injection-molding process. To produce in the brush body segments (20) that are isolated from the rest of the brush body, a mold (10) which comprises three hollow regions (12, 14, 16) is used. Two of these hollow regions (12, 14) that are separate from one another serve for producing the segments (12) and the other regions (18) of the toothbrush (50) from a first component (38). A third hollow region (16) serves for distributing material to the segments (20) that are isolated from one another and from the other regions (18), or the corresponding hollow region (14). The material (22) remaining behind there is removed and sent for disposal. In a further step, connecting elements (42) between the segments (20) and/or the other regions (18) are injection-molded from a second component (39).
    • 本发明涉及通过双组分或多组分注射成型方法生产牙刷(50)或其一部分的方法和装置。 为了在与刷体的其余部分分离的刷体段(20)中产生包括三个中空区域(12,14,16)的模具(10)。 这些彼此分开的中空区域(12,14)中的两个用于从第一部件(38)制造牙刷(50)的段(12)和其它区域(18)。 第三中空区域(16)用于将材料分配到彼此隔离并且与其它区域(18)或相应的中空区域(14)隔离的段(20)。 剩下的物料(22)被取出并送出处置。 在另一步骤中,段(20)和/或其他区域(18)之间的连接元件(42)由第二部件(39)注模。
