8. The molding method of a pressure-compensated drip irrigation tape extrusion molding device as claimed in claim 1, comprising the steps of:

a: adding a material into the device through a feeding device, then starting a motor to drive a screw rod to enable the material to move forwards, heating and melting the material, and extruding the material to form;

b: when the extrusion pressure is smaller, the pressure in the device is reduced, so that gas outside the device can enter the device along the flow channel to push the material to move forwards, meanwhile, the broken material in the air inlet pressurizing structure can be attracted, the gap in the material is reduced, the extrusion pressure of the material is increased, then the gas can be discharged from the exhaust port, and the gas flow and the broken content can be monitored by the exhaust port;

and C, when the extrusion pressure is high, the pressure in the device is increased, so that the gas outside the device can move reversely along the flow channel to inhibit the forward pushing of the material, and then the gas can be discharged from the exhaust port.
