[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. It is 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. For example, the movable unloading mechanism of the injection molding machine recorded in the patent announcement number CN215203153U uses a gear transmission component to make the two sets of stirring blades move in opposite directions. It can ensure that the raw materials will not block the feed port during feeding, and no manual supervision is required, which greatly increases the production efficiency and the stability of unloading. However, this method cannot clean the inner wall of the feed bin, and the stirring blades and conveying auger cannot be disassembled for cleaning after use.
