Abstract
Clamping mechanism for a mold having hingedly connected upper and lower mold members comprises an elongated handle pivoted at one end to the upper mold member to have its opposite end swing from a clamping position in which the handle overlies the upper mold member, to and beyond an upwardly projecting intermediate position. Overlying the pivoted end portion of the handle when the mold is closed is a reaction member having a downwardly facing camming reaction surface and an upwardly facing fulcrum reaction surface. An eccentric cam element on the pivoted end portion of the handle engages the camming reaction surface to clamp the mold shut as the handle is swung towards its clamping position. As the handle is swung to and beyond its intermediate position, an abutment on it, spaced along it from the axis about which it swings, engages the fulcrum reaction surface so that the handle functions as a lever whereby force exerted to swing it farther beyond said intermediate position is applied to lifting the upper mold member against adhesion to a molded part.
