After the liquid plastic is sprayed out, the wind blown out by the machine is used to blow the plastic body to a certain shape of the mold cavity to make a product. This machine is called a blow molding machine. The plastic is melted and quantitatively extruded in the screw extruder, then formed through the mouth film, and then cooled by the air ring, and then pulled by a traction machine at a certain speed, and the winder winds it into a roll.

[0004] The existing blow molding machine needs to wait for the mold to cool down before unloading the material and then continue blow molding, which has a very low production efficiency. Summary of the invention
