MOLD REPLACEMENT DEVICE FOR TWO-MOLD MOUNTING INJECTION MOLDING MACHINE

PROBLEM TO BE SOLVED: To provide a self-traveling mold replacement device capable of replacing two sets of molds in a short time in mold replacement of a two-material injection molding machine having two molds, that is, a movable template side mold and a fixed template side mold, or a molding machine for a stack mold. SOLUTION: The device is provided with a mold replacing truck 1 movable along a guide rail 2 arranged close to and parallel to the injection molding machine 10, a plurality of loading platforms 1a-1d capable of simultaneously mounting at least three sets of the molds 1-4, and free roller belt conveyers 60L and 60R for carrying in and out the mold between the adjacent injection molding machines disposed on all of the loading platforms. Both of the round travelling time of the mold replacing truck 1 and the mold re-loading work time can be dispensed with, stop time by replacement of the mold of the injection molding machine can be drastically reduced, and the mold for replacement for a plurality of the molding machines can be simultaneously installed, and therefore, the mold re-loading work time in a warehouse can be reduced.
