As a further improvement of the utility model, when the male die and the die are matched, the gap between them is 0.01-0.03 mm.

As a further improvement of the utility model, a guide sleeve is provided on the upper base plate, and a guide post that cooperates with the guide sleeve is provided on the lower base plate.

As a further improvement of the utility model, the upper base plate and the lower base plate are correspondingly provided with limiting columns.

As a further improvement of the utility model, a spring is provided between the die fixing plate and the lower base plate, and a spring is provided between the punch fixing plate and the upper base plate.

As a further improvement of the utility model, the upper pressing member is connected to the upper bottom plate through a limit screw.

As a further improvement of the utility model, the punch is connected to the punch fixing plate through an upper backing plate.

Compared with the prior art, the beneficial effects of the utility model are:

By adopting the technical solution of the utility model, the face mask made of composite material of foam and cloth can be molded in one step of punching, which improves production efficiency and product pass rate, and greatly reduces labor intensity and cost.

Detailed ways

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.

As shown in Figures 1 to 3, a face mask die-cutting die of a composite material includes an upper base plate 1, a lower base plate 2, an upper pressing member 3, a lower pressing member 4, a punch 5 and a die 6. The convex mold 5 is arranged below the upper bottom plate 1, the concave mold 6 is arranged above the lower bottom plate 2, the shape of the protruding part of the upper pressing member 3 matches the shape of the concave part of the concave mold 6, and the lower mold 6 The shape of the concave part of the pressing member 4 and the shape of the punch 5 are the same as the shape of the finished product to be prepared, and the punch 5 is matched with the inside of the die 6; the die 6 is sleeved on the lower pressing member 4, the die 6 and the lower pressing member 4 are elastically connected to the lower base plate 2 through the die fixing plate 7; the upper pressing member 3 is sleeved outside the punch 5, and the punch 5, upper pressing The material member 3 is elastically connected with the upper bottom plate 1 through the punch fixing plate 8 . When the inside of the male die 5 and the female die 6 cooperate, the gap between the two is 0.01-0.03mm.

As shown in FIGS. 1 to 3 , the upper base plate 1 is provided with a guide sleeve 9 , and the lower base plate 2 is provided with a guide post 10 cooperating with the guide sleeve 9 . The upper bottom plate 1 and the lower bottom plate 2 are correspondingly provided with limiting columns 11 .
