Background

Blow molding refers to a method commonly used for manufacturing hollow articles, and is also the most commonly used method for processing plastic articles, and comprises the steps of firstly obtaining a semi-molten tubular parison by extrusion or injection molding of a thermoplastic resin, then placing the parison into molds of various shapes in a blow molding machine while the parison is hot or heated to a softened state, immediately introducing compressed air into the parison after the molds are closed, and blowing up the parison closed in a rubber-like state in a mold cavity by means of gas pressure so as to enable the parison to be tightly attached to the inner wall of the mold cavity to form a hollow article, such as a hollow barrel made of plastic. When the mold is opened, the hollow articles in the mold cavity fall and are discharged from the discharge port of the blow molding machine.

In the prior art, after a hollow product is led out from a discharge port of a blow molding machine, workers are required to cut the flash of the hollow product.
