[0001] The present disclosure relates to the technical field of injection molding machines, and in particular to an injection molding device that is convenient for fixed injection molding. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment for thermoplastic plastics or thermosetting plastics using plastic molding molds to make plastic products of various shapes. It is mainly divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity;
