Patent Number: 6,250,906

Title: Stack mold

Abstract: A universal mountable and demountable rack-and-pinion structure for a stack mold includes mounting plates affixed to the mold parts and rack-and-pinion mounting elements which are mountable to and demountable from the mounting plates. This arrangement permits the rack and pinion elements first to be mounted in an approximately correct position for the appropriate proportionation of movement within a molding machine. The device includes an adjustment feature which permits the relative distances between the mold parts to be finely adjusted to ensure correct proportionation of movement. The rack-and-pinion structure is interchangeable for various stack molds.
