In the production process of new energy vehicles, it is necessary to inject the battery case. The injection mold of the battery case is generally suitable for the thermoforming of thermoplastics. Using the hot-melt principle of thermoplastics, the molten plastic is injected into the mold through an injection molding machine. In the cavity, it is then cooled and shaped, and the new energy battery shell mold is opened to take out the plastic product. The injection molding needs to use a fixed mold and a movable mold. The two mold cores are connected to form a group, and then one or more groups are put into the fixed mold by the robot, and the mold is closed and then injected. At present, 3D printing technology is also used for the production of new energy vehicle battery shell molds.
A new model discloses a new energy vehicle battery shell mold based on 3D printing technology. It includes an injection port, a movable mold is arranged at the bottom of the injection port, and an injection channel is arranged through the inner of the movable mold. The bottom of the movable mold is provided with a fixed mold, and the top of the fixed mold is fixedly connected with an intermediate block.
An injection molding part is arranged between the movable die and the fixed die, and movable blocks are respectively arranged on both sides of the middle block. The top of the movable block is fixedly connected with a first limit rod, and the bottom of the movable block is fixedly connected with a second limit rod. A threaded rod is inserted into the internal thread of the movable block, and one end of the threaded rod is provided with a turning handle. This kind of new energy vehicle battery shell mold based on 3D printing technology can closely fit the movable mold and the fixed mold during injection molding, and the shock-absorbing spring is arranged at the bottom of the positioning rod to improve the injection molding stability. By arranging heat conduction holes, heat sinks, and heat sinks, during the injection molding process, heat can be quickly evacuated to the outside, speeding up injection molding cooling, and reducing injection molding waiting time.
