ABSTRACT:
A molding machine has a feed screw arrangement which plasticizes a material and which injects the plasticized material into a mold. The feed screw arrangement includes an input shaft which is mounted in a housing for rotation relative thereto and for axial displacement with and relative to the housing, the input shaft having a splined end portion which extends outwardly of the housing. The housing is mounted on a support for angular displacement about a pivot axis, and a drive is mounted on an auxiliary support for movement with respect to the support for the housing. The drive has an output shaft which has a central opening adapted to matingly receive the splined end portion of the input shaft when coaxial therewith. Relative axial displacement of the two shafts from an extended position in which the splined end portion is matingly received in the central recess to a retracted position in which the shafts are disengaged frees the feed screw arrangement for pivoting about the pivot axis. The support includes a base portion and a reinforcing portion which straddle the housing, and inlet openings for feeding a material into the housing are provided in both the reinforcing portion and the housing, which inlet openings are coaxial with one another and with the pivot axis.
