Description

Technical Field

[0001] The utility model relates to the technical field of iron cores, in particular to a hub motor iron core forming tool. Background Art

[0002] As we all know, hub motor core forming tooling is usually used to manufacture hub motor cores. In the production of hub motor cores, a common method is to use die-casting technology, that is, heating the metal material (usually aluminum alloy or magnetic material) to a liquid state, and then injecting it into a mold of a specific shape, so that it cools and solidifies under high pressure.

[0003] However, after the existing hub motor core forming tooling is completed, when the workpiece needs to be demolded, the staff generally need to find an external vacuum adsorption device to adsorb the workpiece and demold the workpiece. When looking for the vacuum adsorption device again, a lot of time will be wasted. In addition, the vacuum adsorption device is prone to mismatch with the workpiece, which can easily lead to the inability to remove the workpiece and reduce work efficiency. Utility Model Content
