What Is a Mold Rotator?
A mold rotator is a device used to invert heavy objects such as molds and large parts. It is often required because inverting heavy objects with a crane poses significant risks, making a dedicated mold rotator essential. Mold rotators are widely used in mold making, processing, transportation, and maintenance. In addition to heavy items, some mold rotators can handle lightweight boxes.
Uses of Mold Rotators
Mold rotators are industrial machines designed for inverting molds and other heavy objects. Their applications span various industries, including automotive manufacturing, plastic molding, material production, and logistics.
1. Molds
Mold rotators are frequently used in industries involving mold machining, inversion, assembly, insert changeovers, and maintenance. Typical applications include automotive parts, motor parts, plastic molding, and telecommunications equipment manufacturing.
2. Coiled Material
These devices are used to invert heavy coiled materials such as steel plate coils, electrical materials, and wire coils. They are suitable for a wide range of rolled materials used in manufacturing and processing industries.
3. Concrete Products and Product Materials
Mold rotators are applied to invert heavy concrete products, such as building materials and segments. They are also used in metalworking, steelmaking, and logistics for handling materials like metal rolls and other product components. For example, they may reverse paper agents in bookbinding or manage other industrial materials.
4. Machine Parts and Other Heavy Objects
These machines are widely utilized for inverting machine parts, such as components for industrial robots, machine tools, and injection molding machines. Additional applications include machining and assembling diesel engines, machine frames, steel products, safes, transformers, and control panels.
Principle of Mold Rotators
Mold rotators operate using hydraulic cylinders, electric motors, or other drive systems. Common designs include the flat type which is a flat structure that rises with bellows to invert objects. When not in use, it lies completely flat, allowing it to be embedded in the ground or mounted on vehicles.
Other types include the rolling type, which utilizes a rotating cylindrical structure, often maintenance-free with roller gears, and the crane-suspended type which rotates objects using a belt sling and can sometimes perform free rotation.
Typical rotation angles are 90° or 180°, with 180° often achieved by two 90° rotations. The choice of rotation method depends on the product and application.
Types of Mold Rotators
Mold rotators are available in various configurations to suit specific needs:
- Flat Type: Easy to use and can be embedded in the ground or mounted on vehicles.
- Rolling Type: Maintenance-free designs with roller gears.
- Crane-Suspended Type: Allows for flexible rotation, ideal for specific industrial needs.
Load capacities vary, including options for 10t, 15t, 20t, and 30t. The appropriate type should be selected based on the weight and application requirements.
