Problems solved by technology
Therefore, mixed waste plastics have the characteristics of poor fluidity, many impurities, poor uniformity, easy to block injection holes, and poor molding performance. It is difficult to carry out extrusion and injection molding. Effective utilization of waste plastics, a large part of waste plastics can only be landfilled or incinerated in the end, causing environmental burden and secondary pollution

Abstract
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, realizes effective utilization of the mixed waste plastics, and is simple in structure, convenient to install and use, high in production efficiency, low in manufacturing and usecost, suitable for production and forming of various plastic products, high in practicability, wide in application prospect and suitable for large-scale popularization and application, and actual application requirements are met.
Description
technical field [0001] The application belongs to the technical field of recycling waste plastics, and in particular relates to a molding device for mixed waste plastics and a method for using the same. Background technique [0002] With the continuous strengthening of people's awareness of environmental protection, more and more attention has been paid to the recycling and reuse of discarded waste plastics. However, the composition of recycled waste plastics (domestic waste plastics, paper waste plastics, mixed waste plastics) is complex and may contain PE (Polyethylene, polyethylene), PET (Polyethylene Terephthalate, polyethylene terephthalate), PP (Polypropylene, polypropylene), ABS (Acrylonitrile-Butadiene-Styrene Copolymers, acrylonitrile-butadiene-styrene copolymer), PVC (Polyvinyl chloride, polyvinyl chloride), PA (Polyamide, polyamide), PS (Polystyrene, polystyrene) and other plastic components, the melt index of different plastic components is different, for exampl...
