Cavity plates aligning and guiding apparatus in disk injection molding dies

摘要

An apparatus for guiding and aligning fixed side and movable side disk cavity plates of disk injection molding dies of an injection molding device is provided with a plurality of first grooves formed on the outer surface of the fixed side disk cavity plate and a plurality of second grooves formed on the outer surface of the movable side disk cavity plate, wherein each of the first grooves and second grooves form a pair of aligned grooves parallel to the center axes of the fixed and movable side disk cavity plates. The apparatus further comprises a plurality of guide blocks fixed to one groove of a pair of aligned grooves and engaged with the other groove of the pair. The apparatus includes a self-aligning aspect for holding the movable side disk cavity plate in intimate contact with the movable side mounting plate along a plane perpendicular to the center axes of the movable side disk cavity plate and the fixed side disk cavity plate and for slidably supporting the movable side disk cavity plate, such that the center axis of the movable side disk cavity plate is caused to align with the center axis of the fixed side disk cavity plate.
