QUICK CHANGE LOCATOR CLAMP ASSEMBLY FOR PLASTIC MOLDING MACHINE

摘要

A quick change locator clamp assembly for a plastic molding machine having opposed top and bottom platens adapted to receive, mount and support a sectional die having top and bottom clamp plates which comprises laterally spaced pairs of opposed locator clamp assemblies mounted upon and projecting from the platens. Formed within the clamp plates on one side of the molding die are similarly spaced opposed pairs of locator slots. Each clamp assembly includes a locator key mounted upon a platen of a shape to snugly receive the corresponding clamp plate slot for locating the molding die in a predetermined position relative to the platens. A rotatable clamp is mounted upon the key and adapted for operative retaining engagement with an adjacent clamp plate. The sectional die includes a reciprocal ejector plate, there being at least one reciprocal knock-out bar on the molding machine. A reciprocal lifter plate within the bottom anchor plate is connected to the ejector plate and removably interlocked with the knock-out bar.
