ABSTRACT:
An apparatus for manipulating the upper and lower dies of a die set comprising a gantry having a fixture mounted on a main frame for up and down movement, and a sub-frame mounted on the fixture for 180.degree. of rotation. Clamping units are mounted on the sub-frame for clamping the upper die to the sub-frame when the fixture is in a lower position at a work-transfer station. The die set is transported on a cart to the work-transfer station where the upper die is clamped to the sub-frame. The fixture is raised to elevate the upper die to an upper position. The cart is moved away from the work-transfer station carrying only the lower die with it. The upper die is inverted, lowered onto a second cart and it, too, is then moved away from the work-transfer station. Both dies now face upwardly for convenient inspection, cleaning and/or repair. The transporter cart table on which the die set is supported can be rotated to any desired angle such as 90.degree., so that after the upper die has been removed, the lower die may be turned to a position suitable for inspection, cleaning and/or repair.
