摘要： An apparatus simultaneously operates all split locking nuts of an injection molding machine two-platen clamp unit to engage and disengage the split locking nuts with clamp unit strain rods. Each split locking nut has opposed pivoting nut halves operated by coupling rotation of a rotating member through a predetermined angular range to the nut halves via translating members such as push rods. The push rods are pivotably connected to the rotating member and to the nut halves so that the direction of each push rod relative to the rotating member and to the nut half changes with rotation of the rotating member. A method of molding comprises: disengaging split locking nuts from strain rods; positioning a moveable platen assembly to abut mating mold components; simultaneously operating the split locking nuts to engage the strain rods; and, applying force to the abutted mold components sufficient for injection and cure of melt.

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： There is provided a mold clamping apparatus that can prevent a molding material from spouting from a split surface of a mold even if in-cavity resin pressure causes offset of a mold opening force, and can extend the life of the mold. The mold clamping apparatus includes a control device that estimates a mold opening force by mold internal pressure for molding with mold internal pressure being asymmetrical with respect to a center of a mold block, determines a mold clamping hydraulic value applied to each time bar correspondingly to the estimated mold opening force, and distributes hydraulic pressure supplied to each tie bar so that the determined mold clamping hydraulic value is reached.
