If the entire set of barrel specifications for a firework is changed, the base plate 101 may be replaced. By providing the lower tapered nozzle 1016 on the bottom surface corresponding to the measuring cup die 1012, the liquid industrial paraffin can be prevented from flowing along the bottom surface. The action cylinder 5 drives a group of plunger rods 13 to synchronously draw and insert in the vertical direction, so that the synchronous plugging and opening of the runner holes 1015 of the whole group are realized.
