when the cleaning step is executed, the first material level sensor 111 detects that no old raw material exists in the material cylinder 110, the controller controls the second valve 331 to open and start the air pump 312, the air pump 312 enables the material cylinder 110 to be in a negative pressure device, the cleaning material is sucked into the material cylinder 110 until the cleaning material in the material cylinder 110 reaches a set material level height, then the second valve 331 is closed, the air pump 312 stops running, the cleaning material enters the extrusion device 100 from the discharge port of the material cylinder 110 and stays in the extrusion device 100 until the cleaning material is homogenized and then is sprayed out until the cleaning time reaches a cleaning time threshold value, and the old raw material is cleaned through the cleaning material. After cleaning of the old raw material is completed, the first material level sensor 111 detects that no cleaning material exists in the material cylinder 110, the controller controls the first valve 321 to open and start the air pump 312, new raw material is sucked into the material cylinder 110 until the raw material in the material cylinder 110 reaches a set material level height, then the first valve 321 is closed, the air pump 312 stops running, the new raw material enters the extrusion device 100 from the discharge port of the material cylinder 110 and is sprayed out after being homogenized in the extrusion device 100 until the cleaning time reaches the cleaning time threshold again, and cleaning of the cleaning material through the effect of the new raw material is achieved. Before the scraps are ejected, the first lifting mechanism 630 is controlled to drive the movable baffle 620 to ascend relative to the fixed baffle 610 to stop the molten material from entering the mold device 200, the conveying motor is controlled to drive the conveying belt 940 to move, the scraps generated by the cleaning machine are ejected to be in contact with the movable baffle 620, fall to the conveying belt 940 along the movable baffle 620 and the fixed baffle 610, and are conveyed to a scrap collecting position by the conveying belt 940.

After the cleaning is finished, the movable baffle 620 is controlled to descend, the conveyer belt 940 stops moving, and the plastic injection molding step is started. When the plastic injection molding step is performed, the first level sensor 111 determines whether the material is in the material barrel 110 by detecting the material residue of the material barrel 110, and when no material is detected, the controller opens the first valve 321 corresponding to the material storage barrel 320 and starts the air suction pump 312, so as to realize the automatic supply of the raw material.
