Plasticizing assembly comprising a reinforcing skeleton and intended for use in a injecting unit of an injection molding machine

Abstract From the Canadian patent

The reinforcing skeleton comprises skeleton elements, which constitute tracks for engaging stationary rollers for guiding the plasticizing cylinder during the cyclic axial reciprocating motion performed by the injecting unit during the injection molding sequence. Said skeleton elements consist of track bars which are, spaced from the central length portion of the plasticizing cylinder by radial spacers. One of said spacers consists of a plate, which is 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. As a result the, guidance of the plasticizing cylinder is improved and …
