switch 45 alternatively a manually set limit switch is set to be tripped or actuated by an adjustable rod fixed to table 20 at each indexed station switch 45 assures that table rotation stops as best shown in fig4 the aligning device 50 of the invention is mounted to stationary platen 16 underneath table 20 which has any number of locating holes 51 drilled into the underside of ring gear 40 locating holes are preferably positioned in ring gear 40 the function of aligning device 50 is the same as that of the prior art aligning device proximity switch 45 stops rotation of motor 43 at a position whereat an empty lower mold half is moved into molding relationship with the upper mold half on movable platen 15 while table 20 can be stopped at precise positions that position is not sufficiently assured to insure the desired alignment tolerances of the mold half guide pins accordingly aligning device 50 is actuated so that its locating pin 52 fits into a corresponding locating hole 51 for that particular work station this brings the guide pins of one mold half into alignment with the guide holes in the opposing mold half after injection table 20 is now rotated by motor 43 so that the next now empty lower mold half is positioned underneath the upper mold half and the aligning device again actuated to assure alignment of the mold half guide pins the aligning device of the invention assures that locating pin 52 fully seats into tight alignment with a corresponding locating hole 51 at each station it doesn 39 t matter whether locating holes 51 are in a precise geometric alignment with one another what does matter is that locating pin.
