ABSTRACT:
The reinforcing skeleton for use in an injection molding machine comprises skeleton elements having tracks for engaging stationary rollers for guiding a plasticizing cylinder during cyclic axial reciprocating motions performed by the injecting unit during an injection molding sequence. The skeleton elements include track bars spaced from a central length portion of the plasticizing cylinder by radial spacers. One of the spacers has a plate secured to the track bars and to the plasticizing cylinder. Two centering spacers are connected to the track bars and surround the plasticizing cylinder as a sliding fit.
