[0014] Beneficial effects of the utility model:

[0015] When the utility model produces plastic bowls, the downward movement of the die drives the extrusion rod together. During this process, the extrusion plate at the bottom end of the extrusion rod applies pressure to the airbag body inside the protective box, so that the reset tension spring is stretched and the airbag body is compressed. The gas in the airbag body enters the adjustable nozzle through the exhaust pipe and the air supply hose and is sprayed out, so that the plastic residue remaining in the die can be effectively cleaned to prevent the residue from affecting subsequent production and improve the quality of the product. The reset tension spring forms an elastic support for the extrusion rod to prevent the extrusion rod from excessively squeezing the airbag body when descending, causing damage to the device, and further extending the service life of the device.
