[0015] 1. In the present invention, a plurality of fixed frames are equidistantly arranged below the upper mold, and a pressure head is arranged in each fixed frame. During the production process, the material to be molded is placed between the upper mold and the lower mold, and the upper mold is pressed downward, driving the pressure head in each fixed frame to act on the lower mold, so that a plurality of mask air cushions can be generated by a single downward pressure, thereby improving the production efficiency of the mask air cushion;

The pressure head can continue to move upward in the fixed frame, so that the wedge-shaped extrusion block squeezes the wedge-shaped push rod, exposing the tearing device from the fixed frame, making it fit around the pressure head, and then the upper mold continues to press down, so that the tearing device acts downward on the material to be pressed. The pressure head and the tearing device are used in combination, and the mask air cushion can be torn during molding, thereby improving the production efficiency of the mask air cushion.

[0017] 3. In the present invention, a plurality of through grooves are provided on the lower mold directly below the pressure head. After the molding and the edge tearing process, the finished product can fall onto the slope in the base through the through grooves, and then be flushed and cleaned through the water inlet pipe provided on the top of the slope. During the flushing and cleaning process, the finished product falls into the collection device along the slope for collection, which can flush away the dust and other impurities attached to the finished product, thereby reducing the secondary picking of the finished product.

[0047] Working principle of this embodiment: When the device is working, the hydraulic cylinder 32 is started, and the hydraulic cylinder 32 drives the hydraulic rod 32 to extend and retract, which is used to drive the upper mold 4 to move up and down. When the upper mold 4 is pressed down, the pressure head 42 below the upper mold 4 is driven to move down, and the pressure head 42 acts on the material to be pressed on the lower mold 5. Due to the action of the material to be pressed and the lower mold 5, the pressure head 42 moves upward in the fixed frame 41, and the pressure head 42 squeezes the compression spring 43. The pressure head 42 can continue to move upward in the fixed frame 41, so that the wedge-shaped squeezing block 45 squeezes the wedge-shaped push rod 46, and the tearing device 4 4 is exposed from the fixing frame 41 and fits around the pressing head 42. The movable rods 47 and 48 are used to support and fix the tearing device 44. Then the upper mold 4 continues to press down, so that the tearing device 44 acts downward on the material to be pressed. The pressing head 42 and the tearing device 44 are used in conjunction with each other to tear the edge of the mask air cushion during the molding process. Then the finished mask air cushion falls onto the slope 13 in the base 1 through the through groove 51, and then the finished product is washed and cleaned through the water inlet pipe 17 set on the top of the slope 13 to wash away the dust and other impurities attached to the finished product.

[0048] The waste water enters the water storage tank 12 through the filter hole 15, and the finished product passes through the tail end of the slope 13, and the blower 15 dries and dehumidifies it.
