Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
In a vertical platen injection molding machine having a stationary mold portion, a complementary mold portion movable horizontally toward and away from the stationary portion along a fixed line of travel between open and closed positions and a support for the complementary mold portion during movement thereof along its line of travel, said support including a pair of horizontally extending tie rods, the improvement comprising a position adjusting bar for preventing cavity mismatch, said bar comprising an elongated body portion overlying the movable mold portion, a pair of spaced leg portions depending from the body portion and adapted for being mounted on said tie rods for movement of the bar along said line of travel, and adjustable linking means engaging said movable mold portion and said bar for suspendably retaining the movable mold portion in a selected position and for adjusting the vertical position of said movable mold portion relative to said bar within a plane intersecting said line of travel to correct cavity mismatch between said mold portions.
