[0005] Further, several separate moving knives are installed on the moving knife bracket, and the several moving knives are installed side by side.

[0006] Further, the number of the guide columns is not less than two.

[0007] Further, the several guide columns are symmetrically distributed on both sides of the moving knife bracket.

[0008] After adopting the above structure, the beneficial effects produced by the utility model are: for the closing cutter device for a hollow blow molding machine of the utility model, as long as the screws connecting the limit block and the sliding plate are removed, the cutter device body together with the sliding plate can be pulled outwards, which is convenient for maintenance; through the guide rods and guide columns, the stability of the movement of the cutter device body can be improved, and the wear can be greatly reduced; for the split moving knives, when one of the moving knives is damaged, it is convenient to replace it separately without replacing the whole, and the number of moving knives to be installed can also be selected according to needs.
