[0002] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds. During the plastic preparation process of the injection molding machine, it is necessary to load plastic raw materials. Most of the plastic raw materials are stored above the injection molding machine to provide materials for the injection molding machine.

[0003] At present, in order to prevent the injection molding raw materials from solidifying in the storage device, a stirring mechanism is usually installed in the storage box of the injection molding machine. The stirring mechanism is composed of a driving rod rotatably connected to the bottom wall of the storage box and a stirring rod fixedly connected to the outer wall of the driving rod. That is, the driving device drives the driving rod and the stirring rod to rotate to stir the injection molding raw materials.

[0004] In order to adapt to the stirring of injection molding materials of different specifications and qualities, it is necessary to change the inclination angle of the stirring rod. However, the driving rod and the stirring rod are fixedly connected, which is not convenient for angle adjustment, which will affect the full stirring of the materials and result in incomplete and insufficient elimination of material adhesion and agglomeration. Therefore, an anti-condensation mechanism of a material storage device of an injection molding machine is proposed to address the above problems. Utility Model Content
