摘要： A method for injection molding comprises pre-positioning a clamp piston within a cylinder housing to a datum position axially intermediate a clamping position and an unclamped position, the clamp piston affixed to a tie bar, the clamp piston and cylinder housing cooperating to provide a clamp chamber and an unclamp chamber in a clamp cylinder housing on axially opposite sides of the clamp piston for urging the clamp piston towards the clamping and unclamped positions, respectively, when pressurized. Pre-positioning the clamp piston can include leaving a positioning gap between portions of a mold before releasably locking a tie bar to one of the moving or stationary platens, and then advancing the moving platen to substantially close the positioning gap after the releasable locking has been completed. Pre-positioning the clamp piston can include moving a stop member to an advanced position in the cylinder housing, and urging the clamp piston to bear against the stop member before the releasable locking step has been completed.

摘要： An injection molding machine includes a base, a stationary platen fixed to the base for holding a first mold section, and a moving platen for holding a second mold section. The moving platen is slidably supported on a platen slide surface fixed to the base and moveable along a machine axis between a mold closed position, in which the moving platen is drawn towards the stationary platen, and a maximum daylight position, in which the moveable platen is spaced axially apart from the stationary platen by a platen opening. The machine further includes a carriage support structure slidably supporting a stack mold carriage for holding a mold center section. The stack mold carriage is translatable parallel to the machine axis between a carriage advanced position and a carriage retracted position spaced axially apart from the carriage advanced position by a carriage stroke length. The carriage support structure includes a pair of beams removably fixed relative to the base, the beams extending parallel to the machine axis and spaced apart from each other by a lateral spacing, each beam having a beam length that is less than the platen opening and greater than the carriage stroke length.
