Mixed waste plastic forming device and using method thereof

The invention discloses a mixed waste plastic forming device and a using method thereof.The mixed waste plastic forming device comprises a fixed die, a movable die and an intercepting mechanism, wherein a containing cavity with an opening in one side is formed in the fixed die, the containing cavity is provided with a bottom face opposite to the opening, and a feeding port communicated with the containing cavity is formed in the geometric center of the bottom face; the movable mold can be inserted into the containing cavity from the opening, the shape of the end face of the movable mold is matched with the shape of the section of the containing cavity, and a mold cavity for mixing waste plastic regenerated products is formed between the movable mold and the fixed mold. The intercepting mechanism can cut off or conduct the feed port. According to the invention, one-step molding of a hybrid waste plastic regenerated product can be realized; the device solves the problem of recycling of mixed waste plastics, rea
