Definitions
- the invention relates to a locking device in the form of a die casting machine for
- Plastics with a fixed platen that can be operated by a linear motor
- a closing unit is known from DE 37 15 161 A1, in which the end plate forms a linear motor together with the pressure ram, with the
- Three-phase windings are arranged and the pressure stamp is designed as a runner rail
- the closing force is still to be actively applied during the injection, holding pressure and cooling phase, which leads to permanent, considerable energy consumption.
- an injection molding machine is known from EP 0 280 743 B1, in which a linear movement element, here a metering / injection screw, is used as the electrical one
- Linear motor is formed.
- the linear motor has a cylindrical shape which corresponds to a movable element having a circular cross section.
- Solenoid motors only achieve a fraction of the forces that can be achieved by linear motors in single or multiple comb designs.
- Solenoid motors require a higher manufacturing effort than single or multiple comb motors.
- a plastic injection molding machine in which at least some of the working elements are driven by electrically superconducting magnet arrangements, the conductors of which are cooled below the transition temperature by a cooling medium.
- One of these working elements is a toggle for closing the mold, in which electro-superconducting linear electric motors are provided for linear movement.
- This device has the disadvantage that the transition temperature required to achieve superconductivity must be achieved by a conductor winding which consists of a special alloy and which is to be cooled on the other hand.
- a conductor winding which consists of a special alloy and which is to be cooled on the other hand.
- Such an alloy consists in particular of the expensive metal lanthanum or Ytt ⁇ em, barium, copper and oxygen
- the crack temperature is reached in particular by liquid nitrogen and is therefore technically sophisticated
- the aim of the invention is to provide a locking device of the generic type which enables simple, constructive means to move and hold the movable platen with little energy and without contamination
- At least one linear motor is connected to a force transmission element that is connected to a lever mechanism.
- This force transmission element can be designed as a crosshead or as an actuating frame.
- Double toggle levers are used here, with preference given to four-point and five-point toggle levers
- the geometry of the individual levers and the control program is selected so that in the closed position of the movable platen, this is held without energy being consumed during the closing phase
- the linear motors are between the force transmission element and either the end plate or the movable one
- the stationary part is attached to the end plate and the mobile part to the power transmission element. In this way a drag chain is avoided.
- a column of the chess unit is used as the reaction rail of the nuclear arm motor
- a locking element which holds or engages at least one lever in a positive or non-positive manner in the closing phase.
- the locking elements are designed such that a drive is only required for locking or unlocking
- linear motors arranged in pairs are used. This design essentially compensates for the splitting forces
- the principle of the uninhibited has no limitation of the speed of movement or the force, as it is associated with a gearbox or spm release
- Figure 3 Locking device designed as a brake.
- Figures 1 and 2 show an injection molding machine with a fixed platen 11 and a movable platen 12 and an end plate 13. On the fixed platen, a clamping cylinder 15 is arranged. The tool 16 is fastened to the tool clamping plates 11, 12.
- FIG. 1 shows a die casting machine with a force transmission element, which is designed as an actuating frame 21.
- the movable tool plate 12 is located in the upper half of the figure
- a five-point toggle lever 31-33 is arranged between the movable tool mounting plate 12 and the actuating frame 21.
- the inductor combs 41 and 43 of two linear motors are provided in pairs as double-chamber motors.
- the reaction rails 42 and 44 are connected to the end plate 13.
- the actuating frame 21 is connected to the end plate via a drag chain 45.
- a four-point toggle lever 31-33 is provided between the platen 12 and the end plate 13.
- an inductor comb 41 is arranged, which as a
- reaction rail 42 configured spar 14.
- the spar 14 is guided through a second inductor comb 43 which is arranged in the movable tool mounting plate 12.
- the force transmission element is designed as a cross head 22
- Inductor comb 42 arranged, which is connected to the crosshead 22 via a reaction rail 44
- a five-point toggle lever is connected to the crosshead 22 between the movable platen 12, which is in the open position
- FIG. 3 shows in section a lever 33 which can be held by a non-positive component 51.
- component 51 is designed as a pair of pliers which can be held in its closed position by means of a spring 54 a linear motor 53 is provided on the lever 33 at the opposite end of the pliers
- the non-positive component is designed as a disc brake, which holds the lever 33 via springs 54 and is evident via a linear actuator 53
- FIG. 4 shows a form-fitting component, here in the form of a wedge 55, which can be moved against the lever 33 by a linear motor 53
- FIG. 5 shows a free-space machine with the fixed tool mounting plate 11, which is connected to the movable tool mounting plate 12 via a lever 33 and a lever 31 connected to it in an articulated manner.
- the toggle lever consisting of the levers 31 and 32 is connected to the linear motor constructed from the reaction rail 42 and the inductor comb 41.
