    • An injection moulding process for making a toothbrush involving a stack mould assembly of at least three mould blocks (1, 2, 3, 4) arranged for use along a longitudinal stack axis (A—A), with two end mould blocks (3, 4), and an intermediate mould block (1, 2), with part mould cavities (11A, 21, 31, 41, 51) in the blocks. Plastic toothbrush skeletons are made in a cavity (11A, 21, 31) between the intermediate block (1, 2) and one end block (3), then elastomer parts are made in a cavity (41, 51) between the intermediate block (1, 2) and the other end block (4). Preferably the intermediate block (1) rotates so its part cavity (11A) faces the other end block (4). Stack mould assemblies (1, 2, 3, 4) for this process are provided. The assembly (1, 2, 3, 4) provides a compact mould with high output.
    • 一种用于制造牙刷的注射成型方法,所述牙刷包括布置成沿纵向堆叠轴线(AA)使用的至少三个模块(1,2,3)的堆叠模具组件,其具有两个端部模块(3,4) ,以及在块中具有部分模腔(11A,21,31,41,51)的中间模块(1,2)。 在中间块(1,2)和一个端块(3)之间的空腔(11A,21,31)中制造塑料牙刷骨架,然后将弹性体部分制成在中间块 (1,2)和另一端块(4)。 优选地,中间块(1)旋转,使其部分空腔(11A)面向另一端块(4)。 提供了此过程的堆叠模具组件(1,2,3,4)。 组件(1,2,3,4)提供了高输出的紧凑型模具。
