ABSTRACT:
A quick change locator wedge clamp assembly for a plastic molding machine ving opposed stationary and movable platens adapted to receive, mount and support a sectional die having stationary and movable clamp plates which comprises laterally spaced pairs of opposed locator wedge clamp assemblies mounted upon and projecting from the platens. Similarly spaced pairs of opposed wedge clamp guides are mounted upon the clamp plates on one side of the molding die and have 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 wedge ramp slot for locating the molding die in a predetermined position relative to the platen. A wedge is yieldably mounted upon and extends transversely of a key and has a tapered undersurface adapted for operative retaining engagement with the adjacent wedge ramp guide. Additional clamp assemblies are mounted upon the clamp plates upon the other side of the molding die for securing the clamp plates to the platens. 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 movable clamp plate is connected to the ejector plate and removably interlocked with the knock-out bar.
