The specific embodiment

Be illustrated in figure 1 as the utility model mould vertical view, Fig. 2 a is depicted as the structural representation of the utility model mould.

Shown in Fig. 2 a, air chamber rubber barrier film mould in the utility model comprises infrabasal plate 1, middle substrate 2, upper substrate 3, counterdie 11 is installed on the infrabasal plate 1, pressure ring 21 is installed on the middle substrate 2, patrix comprises partial vulcanization core rod 33 and whole sulfuration core rod 34, and upper substrate 3 is made of the two

boards

31,32 that interfixes by screw 36.Partial vulcanization core rod 33 is installed on the plate 31, and whole sulfuration core rod 34 is installed on the plate 32, and the back-to-back setting of two core rods also is provided with two jointed shafts 35 on the upper substrate 3.Be provided with the guider that quadruplet is made of guide pillar 4 and fairlead between middle substrate 2 and the infrabasal plate 1.Wherein guide pillar 4 fixes with infrabasal plate.Be provided with anti-canvas fold structure between described pressure ring 21 and the counterdie 11.
