Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to an injection molding equipment for PCR plastics. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines are generally divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics to make them ejected and fill the mold cavity. PCR plastic literally means post-consumer recycled plastics. This type of plastic can be used as an injection molding machine as an injection molding equipment for injection molding of various products.

[0003] PCR plastic is a kind of recycled plastic. When it enters the barrel of the injection molding equipment for injection molding after recycling, some of the recycled plastics are mixed with some impurities and dust. These impurities and dust often affect the injection molding quality of PCR plastic at the injection molding equipment after entering the barrel with the PCR plastic. Therefore, it is necessary to make corresponding improvements to the injection molding processing of the recycled PCR plastic. To this end, we propose an injection molding equipment for PCR plastic.
