[0025] Embodiment one, a double-layer composite film inner composite die convenient for upper and lower die opening and closing, comprising: side baffle 1.

[0026] Specifically, the side baffle 1 is provided with two, and the upper die body 2, the middle die body 3 and the lower die body 4 are sequentially stacked from top to bottom between the two side baffles 1. The side surfaces of the upper die body 2, the middle die body 3 and the lower die body 4 are fixedly connected by bolts with the side baffles 1. The side baffles 1 can position the edges of the upper die body 2, the middle die body 3 and the lower die body 4, and at the same time avoid leakage of internal medium from the side edges. The adjacent two of the upper die body 2, the middle die body 3 and the lower die body 4 are fixedly connected by die body fastening bolts 5. The die body fastening bolts 5 are mainly used for clamping the upper die body 2, the middle die body 3 and the lower die body 4. When installing, the bolts between the upper die body 2, the middle die body 3 and the lower die body 4 need to be tightened and fixed first, and then the side baffles 1 are installed on the side surfaces of the upper die body 2, the middle die body 3 and the lower die body 4. In this way, the bolts on the side baffles 1 can be avoided from being bent and deformed. When opening the mold, the bolts on the side baffles 1 need to be loosened first, and then the bolts between the upper die body 2, the middle die body 3 and the lower die body 4 are loosened. In addition, a die mouth adjusting plate 22 is arranged at the die mouth of the upper die body 2. The lower end of the die mouth adjusting plate 22 is bent and inclined.
