8. A method of using a blow moulding machine to facilitate ejection of moulds as claimed in any one of claims 1 to 7, characterised by: the method comprises the following steps:

firstly, connecting the whole device with an external power supply, after the blow molding machine is finished, firstly, starting a hydraulic cylinder (12), enabling an output end of the hydraulic cylinder (12) to drive two blow molding dies (4) to slide towards one side away from each other, so as to drive a lower connecting block (54) to slide in a lower sliding groove (53), enable a lower gear plate (55) to slide in a lower gear plate groove (56), and finally drive a linkage gear (514) to rotate, so as to enable the linkage gear (514) to drive an upper gear plate groove (510) and an upper connecting block (58) to slide, and finally drive a cutting blade (511) to slide in a limiting frame (52), so as to enable the two cutting blades (511) to slide towards one side and enable the two cutting blades (511) to cut off the upper end of a raw material;

secondly, when the two blow molding dies (4) slide towards the far side, the side wall of the finished product is separated from the inner wall of the mold cavity (9), meanwhile, the finished product can be positioned at the middle position of the two blow molding dies (4) by clamping the two push plates (65), when the blow molding dies (4) move to be contacted with the limiting plate (610), when the limiting plate (610) is extruded, the limiting plate (610) can slide towards the side far away from the limiting plate, and finally the push plate (65) is driven to slide towards the side far away from the limiting plate, in the process, the piston plate (62) slides in the air inflation frame (61) to compress the air in the air inflation frame (61), so that the high-pressure gas in the inflating frame (61) flows out through the connecting gas pipe (67) and the high-pressure exhaust head (68), and finally under the pushing of the high-pressure gas flow, the side wall of the finished product can be easily separated from the push plate (65), and the damage of the finished product in demoulding is avoided;

thirdly, when the two blow molds (4) slide towards the side far away from each other, the connecting rotating rod (74) can be driven to rotate, the blow molds (4) can be driven to pull the connecting rotating rod (74) to be positioned in the rotating groove (72) to slide, finally, one ends of the connecting rotating rod (74) far away from the blow molds (4) are driven to rotate and slide towards the side near the blow molds (4), the connecting push rods (76) can push the connecting side plates (712) to slide towards the side near the blow molds (4), so that the telescopic rods (710) are driven to stretch the return springs (78), the telescopic rods (710) are positioned in the fixed sleeves (77) to slide, finally, the pushing blocks (711) slide towards the two blow molds (4), and the finished products between the blow molds (4) are pushed out from the blow molds (4);

and fourthly, finally pulling the pull handle (83), driving the protective cover plate (82) to slide on the slide rail (81) to the side away from the slide rail, finally opening the front side of the protective frame (2), and taking out the pushed finished product from the protective frame (2) to finish the demoulding of the blow molding machine.
