[0002] As we all know, injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is mainly divided into vertical, horizontal and all-electric types. Modified plastics refer to plastic products that are processed on the basis of general plastics and engineering plastics through filling, blending and reinforcement to improve the flame retardancy, strength, impact resistance and toughness of the plastic products.

[0003] At present, in the related technology, after searching, the utility model with patent publication number CN214820270U discloses an injection molding machine for modified plastic processing; it includes a workbench, a first fixed plate is fixedly connected to the top of one side of the workbench, a second fixed plate is fixedly connected to the top of the workbench on the side away from the first fixed plate, a plurality of cylinders are evenly fixedly connected to the side wall of the first fixed plate close to the second fixed plate, an outer mold is commonly fixedly connected to the side of the plurality of cylinders close to the second fixed plate, a third fixed plate is fixedly connected to the top of the workbench on the side away from the second fixed plate, an injection barrel is provided on the side wall of the third fixed plate close to the second fixed plate, and a first fixed ring is fixedly connected to the outer wall of the injection barrel.
