[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5The utility model provides a technical solution: a rotary demolding injection mold, including a mold body 1, a molding cavity 3 for injection molding a workpiece 4 is opened on the mold body 1, a bearing seat 2 is installed on the mold body 1, a molding rod 5 is arranged on the bearing seat 2, and the molding rod 5 extends into the molding cavity 3 to complete the injection molding of the workpiece 4; a driving member is arranged on the mold body 1, and the driving member drives the bearing seat 2 to move on the mold body 1 so that the molding rod 5 is pulled out from the molded workpiece 4.

[0019] Specifically, the rotary demolding injection mold includes a mold body 1. At the same time, it is known that the mold body 1 is also provided with a movable mold that is compatible with the mold body 1. When injection molding is required, the movable mold is molded with the mold body 1. After the injection molding is completed, the movable mold is separated from the mold body 1 to facilitate the demolding operation. A molding cavity 3 for injection molding a workpiece 4 is provided on the mold body 1. Specifically, the molding cavity 3 is provided between the movable mold and the mold body 1 to facilitate the injection molding operation. A bearing seat 2 is installed on the mold body 1, and a molding rod 5 is provided on the bearing seat 2. The molding rod 5 extends into the molding cavity 3 to complete the injection molding of the workpiece 4; specifically, the molding rod 5 is arc-shaped and is used to inject a specific workpiece 4. The mold body 1 is provided with a driving member, which drives the bearing seat 2 to move on the mold body 1. Specifically, the bearing seat 2 is rotatably connected to the mold body 1, and the driving member drives the bearing seat 2 to rotate on the mold body 1, so that the forming rod 5 is pulled out from the formed workpiece 4, and the forming rod 5 is separated from the workpiece 4. Then, the workpiece 4 can be ejected or clamped out by a manipulator, so as to facilitate the demolding of the workpiece 4 from the molding cavity 3. Specifically, the injection mold will be used in conjunction with a mold frame, such as a movable mold adapted to the mold body 1, which is installed on the mold frame, and the driving member is also installed on the mold frame to facilitate driving the bearing seat 2 to rotate. Therefore, when the injection mold needs to be used, the injection molding operation is completed by closing the movable mold with the mold body 1. When the workpiece 4 after injection molding needs to be demolded, the supporting seat 2 is driven to rotate on the mold body 1 by the driving member. During the rotation of the supporting seat 2, the molding rod 5 is driven to rotate inside the molding cavity 3, so that the molding rod 5 is separated from the workpiece 4. After that, the workpiece 4 can be ejected or clamped out using a robot to facilitate the demolding operation of the workpiece 4, meet work needs, and have a good use effect.
