Abstract: A pair of form keys and a method for forming reverse drafts in foam parts are disclosed. A male form key is reciprocally mounted in a first mold half in a retracted position. A female form key is rotatably mounted in a second mold half in a neutral position. The first mold half includes a first drive pin that when engaged, moves the male form key into engagement with a foam sheet to form an undercut as the first and second mold halves are closed. The first mold half also includes a second drive pin that engages the female form key as the first and second mold halves close rotating the female form key into engagement with the foam sheet and the male form key. After closure of the mold and the product is formed, the mold is opened. As this occurs, the drive pins are disengaged and the male form key retracts and the female form key rotates to their neutral positions. The formed product may then be stripped from the mold while maintaining the reverse draft or undercut.

Abstract: Apparatus for molding plastic caps having inclined tabs integral with the lower edge of the cap skirt and radially inwardly extending ribs integral with the inner surface of the cap skirt. The tabs and ribs are formed by a plurality of blades having recesses on the ends thereof corresponding to the configurations of the tabs and ribs. The blades are mounted on a core and extend into a female mold having a cup-shaped cavity. A linear drive member is mounted on a fixed plate assembly and connected to a ratchet sleeve rotatably mounted on a movable plate assembly. The end of the ratchet sleeve is provided with circumferentially spaced teeth engaging the lower peripheral edge of the cap skirt. Movement of the movable plate assembly relative to the fixed plate assembly causes the ratchet sleeve to rotate to move the molded tabs and ribs away from the recesses of the blades so that the finished cap can be stripped from the apparatus.

Abstract: A mold assembly for a container closure includes a mold portion with a stripper ring adapted for engaging a shoulder of the closure, and a threaded core having an external, asymmetrical helical thread defining an internal, asymmetrical helical thread of the closure. The external, asymmetrical helical thread has a ramped surface defining a ramped surface of the internal, asymmetrical helical thread. Relative linear movement between the stripper ring and the threaded core causes withdrawal of the threaded core from the closure in a linear direction. The ramped surfaces of the internal and external, asymmetrical helical threads cooperate to facilitate the withdrawal.

Abstract: The invention discloses a microelectroforming mold using a preformed metal as the substrate and its fabrication method. Using a preformed metal as the substrate can avoid deformation of the microelectroforming mold due to residual stress in the electroforming metal. The fabrication method disclosed herein includes the steps of: forming a layer of bonding material on a surface of the preformed metal substrate after machining; forming a high aspect ratio photoresist microstructure on surfaces of the metal substrate and the bonding material; putting an electroforming material into the gaps of the photoresist microstructure to form an electroforming metal microstructure; and using a thermal process to bond the metal substrate and the metal micro structure by the bonding material and simultaneously bum off the photoresist microstructure to form a micro-electroforming mold. The invention shortens the electroforming time to be one third of the prior art, elongating the number of times the micro-electroforming mold can be used by a factor of more than three.
