Description

Technical Field

[0001] The utility model relates to the technical field of film pressing, in particular to an upper and lower structure for a film pressing structure. Background Art

[0002] After the product is produced, a layer of film will be attached to the surface of the product to prevent it from being contaminated by dust. To ensure that the film is completely attached, most current manufacturers use a film pressing device to press the film onto the workpiece. The corresponding structure of the film pressing device mainly includes a lower mold structure for fixing the workpiece and an upper mold structure for pressing down.

[0003] For example, Chinese patent CN108971941B discloses a membrane cover pressing structure for an industrial watch, which includes a lower mold adapted to the shape of a workpiece and an upper mold structure fixedly mounted on a cylinder; during use, the upper mold is driven downward by the cylinder to press the film tightly onto the workpiece.
