Abstract
Apparatus for vertically adjusting the position of a lower mold relative to an upper mold to control the shut height or spacing between the upper and lower molds when they are moved between vertically spaced apart, open positions, and closed positions engaging opposite sides of a thermoplastic sheet of material to form an object therein. A plurality of toggle links are pivotally coupled to each other and to the mold and frame for determining the final position of the mold and the closed position. The toggle link mechanism for the lower mold is mounted on the frame via a horizontally adjustable wedge mechanism which vertically adjusts another cooperating wedge mounting one pivotal end of the lower toggle links.
