Definitions

  • the invention relates to a die casting machine for processing molten metals, which a machine stand with one arranged on it Has a casting nozzle and a mold closing unit that can be aligned with it, that of a crosshead and a fixed and one on guide columns stored and against this pushable movable mold mounting plate exists and adjustable in height on one on the machine stand supported inclined guide surface is stored.
  • a die casting machine of this type is known from DE 30 18 288 A1.
  • the mold clamping unit is on guide rails inclined at an angle to the horizontal stored. Because depending on the type of forms to be used different sprue positions are provided on the mold, it becomes necessary to adjust the height of the locking part.
  • the pouring nozzle is at Hot chamber die casting machines are known for being constantly in the Melt the remaining casting container in a certain position so that the sprue part of the mold must be adapted to this pouring nozzle.
  • DE 34 23 056 C2 describes a height adjustment device for the mold clamping unit a hot chamber die casting machine known in the one has assigned a pressure cylinder to the crosshead and a second one Pressure cylinder arrangement provided on the fixed platen and supported the two pressure cylinders on the machine stand. Through the joint pressurization of the two pressure cylinder arrangements the mold clamping unit can also be adjusted in height adjust.
  • this type of construction is relatively complex because of the pressure medium circuit can be precisely controlled using appropriate switching valves got to.
  • the present invention is therefore based on the object of a hot chamber die casting machine of the type mentioned at the beginning that simple height adjustment that can only be achieved with mechanical elements is possible, which is simple and space-saving.
  • the lifting frame has at least two of the same type a parallelogram arranged lever pairs adjustable in height which are pivotable in the same direction. So the lifting frame can be assign a pair of levers in the area of the two lifting frame ends, so that when a common drive is provided for the pairs of levers an exact parallel lifting of the lifting frame is possible.
  • this can be done in a very simple manner as a common one Drive a mechanical connection between the pairs of levers provided with a drive acting in the direction of the connection his.
  • the pairs of levers can each as two lever arrangements articulated to a pair of toggle levers be formed, of which a lever is pivotable on the lifting frame and the other is mounted on the machine stand.
  • the common drive attacks in the connecting joint of both levers.
  • a common drive can be a connecting rod or a Rack may be provided, with an electric motor, for example, as the drive can be used with a gear.
  • a hand crank a linear motor or an eccentric crank drive or a so-called pneumatic muscle can be used as a drive.
  • a mechanical Element for example a push rod, moved by the drive, which then operated both pairs of toggle levers together, so that a exact synchronization of the lifting frame and thus the mold clamping unit is guaranteed. Complicated controls are not necessary. Since this lever drive can be integrated in the lifting frame, there is also no additional space for arranging a separate one Lifting device needed.
  • vertical guides for the lifting frame for example as on the machine stand solid vertical bolts or rails are formed can be, which engage in guides of the lifting frame or vice versa.
  • Guide bolts or rails protrude from the lifting frame and are guided in corresponding vertical guides of the machine stand.
  • the only figure shows a hot chamber die casting machine that has a machine stand 1 on which a lifting frame 2 vertically is arranged adjustable in that vertically from the machine stand 1 engage projecting guide bolts 3 in the longitudinal guides of the lifting frame.
  • the lifting frame is at an angle of inclined approximately 5 ° to the horizontal, so that it has an upper guide surface 4, which also extends obliquely to the horizontal.
  • a locking unit 5 is provided, which consists of a Crosshead 6, a drive cylinder 7 associated therewith for one Toggle lever mechanism 8 and one connected to it movable platen 9 is constructed.
  • the movable platen 9 is slidably mounted on guide columns 10 and interacts with a fixed platen 11 shown in FIG Location against a locking device and is therefore in a certain Position in relation to a sprue nozzle indicated by dash-dotted lines 12 is held.
  • the sprue nozzle 12 is not shown in FIG Way in connection with a casting container, which in one within a movable crucible immersed molten metal.
  • This The casting container is equipped with a casting piston device, via which the Melt to the sprue nozzle 12 and thus into the between the fixed platen 11 and the movable platen 9, is pressed in the embodiment, not shown.
  • the figure shows that the lifting frame 2 in the area of its two ends is each provided with levers 13 and 14, each via a connecting joint 15 with a second lever 13a of equal length or 14a are articulated.
  • the levers 13 and 14 form one Parallelogram crank gear and can be pivoted on the lifting frame 2, the levers 13a and 14a each pivotable at the articulation point 16 on the machine stand 1 stored.
  • the levers 13, 13a, 14 and 14a therefore form one Kind of a toggle.
  • the two articulated connections 15 are in turn articulated in connection with a push rod 17 of a screw jack, the longitudinal drive of the push rod 17 via an electric motor 18 and a gear 19 takes place, which the rotary movement of the electric motor 18 for example via a rack in the longitudinal movement the push rod 17 implements.
  • the push rod 17 is one Coupling joint 20 connected to the driven part 21 of the transmission 19.
  • the linear actuator i.e. the arrangement of the levers 13, 14, 13a, 14a also integrate into the lifting frame 2, if this with appropriate cavities is provided. This leads to a protected one Execution of the linear actuator and a very space-saving design.
