2 are provided to form a traction state with respect to the lower peeling seat 8.

The reason why the lower peeling seat 8 and the hydraulic cylinder 82 are separately provided below the male die 4 will be described below. The plastic residue formed during the production process of the injection bottle 3
As shown in FIG. 2, the lower part of the injection bottle 3 is pressed and flattened by the merge of the female die 5 and the male die 4. Therefore, if the lower peeling seat 8 and the hydraulic cylinder 82 are independently provided only below the male die 4 and the inner surface of the lower peeling seat 8 is pulled down while being held in close contact with one surface of the female die 5, The plastic residue at the bottom of the injection bottle can be peeled off.
On the other hand, the plastic residue at the top of the injection bottle has a trumpet-shaped wide mouth because it is necessary to blow air to form a hollow, and the wide mouth portion is separated from the male die 4 and the female die 5 by peeling. If it is sandwiched between two opposing surfaces of the seat 6 and peeled upward, it can be peeled with a uniform application force.

The combination of the present invention is shown in FIG. The hydraulic cylinder 71 and the hydraulic cylinder 82 are both connected and fixed to the machine base 9 shown in FIG. 7, and apply a force by hydraulic power supplied by a hydraulic pipe.

As shown in FIG. 7, when the electrolyte injection bottle 3 is manufactured according to the present invention, the male die 4 and the female die 5 are combined and mounted on a machine base 9 shown in FIG. Further, the material is pushed in and air is blown into the semi-molded product of the injection bottle 3 shown in FIG. 2 (this manufacturing process is not the point of the present invention, so further description is omitted).

Next, please refer to FIGS. When the injection bottle 3 is dried and solidified, the hydraulic cylinder 71 of the push-up seat 7 is operated upward, the push-up arm 73 pushes up the push-up column 73, and the push-up column 73 holds the male die 4 and the female die 5. The inside of the hollow pillar 42 is raised, and the upper peeling seat 6 connected to the top end of the push-up pillar 73 and integrated is raised at the same time. As the two symmetrical upper release seats 6 rise with the pinching surfaces 64 of their inner end faces pressed against each other, the plastic residue is removed and a peeling effect is achieved.

When the hydraulic cylinder 82 below the male die 4 is operated, the inner end face of the lower peeling seat 8 is pulled downward while being in close contact with the wall of each forming tank 41 of the female die 5, whereby the injection is performed. The plastic residue at the bottom of the bottle is peeled off. Thus, when the injection bottle is manufactured according to the present invention, all the plastic residue is peeled off, and the completed injection bottle 3 shown in FIG. 3 can be obtained.
