Abstract
An injection-molding die, which comprises a movable die platen guided via crossbeams is provided, wherein an adjusting element is positively connected to each crossbeam and can be adjusted axially relative to the crossbeam via a central drive and the position of the die platen changes relative to the crossbeams. An apparatus and method is provided in which at least one of the adjusting elements can be locked against an axial movement and against rotation by means of a fixing device. The fixing device may be a piston element in a closure cover arranged on the movable die platen.
Claims21
A device for adjusting the installation height of an injection-molding die, comprising a movable die platen guided via crossbeams, an adjusting element being positively connected to each crossbeam and being adjustable axially relative to the crossbeam via a central drive, the position of the die platen being changeable relative to the crossbeams, at least one of the adjusting elements being lockable against an axial movement and against rotation by a fixing device.
A process for adjusting a height of an injection-molding die, in which a movable die platen is guided via crossbeams and its position relative to the crossbeams can be changed via adjusting elements, the adjusting elements being connectable positively to the crossbeams and rotatable via a central drive around the latter, as a result of which axial adjustment of the relative position to the crossbeams takes place, the position of the adjusting element being fixable by actuating a fixing device, the method including adjusting the position of the movable die platen relative to the crossbeams.
An injection-molding machine, comprising:
- an injection-molding die including a movable die platen guided by a plurality of tie bars;
- at least one adjusting element that adjusts a distance between the die platen and the plurality of tie bars, the at least one adjusting element being movable along a longitudinal axis of a tie bar;
- a drive that actuates the at least one adjusting element to cause movement between the at least one adjusting element and the tie bar;
- and
- a fixing device that locks the at least one adjusting element in place to prevent movement between the at least one adjusting element and the tie bar.
A method for operating an injection-molding machine that includes a movable die platen guided by a plurality of tie bars, and at least one adjusting element for adjusting a distance between the die platen and at least one of the plurality of tie bars, comprising:
- actuating the at least one adjusting element to cause movement between the at least one adjusting element and the at least one of the plurality of tie bars;
- and
- locking the at least one adjusting element in place to prevent movement between the at least one adjusting element and the tie bar.
