[0003] Reference publication number CN213198961U is a paper cup forming mold of a paper cup machine, which drives the ejector rod to move axially along the ejector guide sleeve through a power source, thereby driving the cup mold head to move outward to eject the paper cup. After the paper cup is ejected, the ejector rod is reset under the action of the reset mechanism to wait for the next ejection operation. In order to facilitate the paper cup to smoothly separate from the cup mold body, an external air source is used to assist the ejection and demoulding, generally by introducing compressed air. Specifically, the compressed air can enter the air channel of the ejector rod from the vent hole. When demoulding, the compressed air is introduced into the ejector rod. The compressed air acts on the connection between the cup mold body, the cup mold head and the inner wall of the paper cup to cooperate with the ejector rod to eject the cup mold head to realize the smooth demoulding of the paper cup. In this way, the deformation and damage of the paper cup can be effectively avoided, and the quality of the paper cup can be improved. However, the following problems still exist:
