| 摘要 |
The present invention relates to a magnetic articulated sliding undercut mechanism for use with an apparatus for forming a plastic article from a sheet of plastic material heated to a predetermined forming temperature. The magnets are situated below the sliding undercut and, along with the stripper plate mechanism, help return the sliding undercut mechanism to its starting position after the thermoforming process has been completed. The use of the magnets also allows the sliding undercut mechanism to set itself in the same position every time it returns back to its molding or relaxed position.
