Description

Technical Field

[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 is equipped with a hopper. The existing feeding method is mostly to manually add plastic raw materials into the hopper. Since there is a certain height difference between the hopper and the ground, especially for vertical injection molding machines, it is more laborious to manually lift the barrel when adding materials. Therefore, in the prior art, a feeding mechanism is often set to automatically lift the barrel and move the barrel to the top of the injection molding machine hopper. However, since the discharge end of the barrel is at a certain height from the injection molding machine, the plastic raw materials are easy to splash out when adding materials, resulting in waste. For this reason, a feeding mechanism for an injection molding machine is proposed. Utility Model Content
