Definitions

  • the invention relates to a casting plant, in particular for die casting.
  • Molten metal with a casting furnace, a casting mold and a sliding closure, wherein the casting furnace is provided with a floating mounted riser, which can be claimed by the shear forces caused by the shear.
  • the molten metal in the casting furnace is known to be fed to the casting mold via the riser of the furnace and the flow channel of the sliding closure positioned between the furnace and the casting mold is pressed against both the head of the riser and against the bottom of the mold. As a result, the metal-tight melt supply to the mold is ensured.
  • the riser of the furnace is floatingly mounted on this by means of a Federbalges, so that it can easily feathers in pressing.
  • this has the consequence that when pressing the sliding shutter then acting on the riser transverse forces him act on the side, with the risk that the riser can tilt. As a result, the metal-tightness and thus the functionality of the system is no longer guaranteed.
  • a pressure vessel is provided with a casting tube arranged at its upper outlet.
  • the vertically positioned pouring tube has an upper pouring head, which can be associated with a transportable casting mold for pouring. It is also provided at least one surrounding the casting tube bellows, which serves to ensure that the compressed gas in the container can not escape.
  • the invention has for its object to provide a casting plant of the type mentioned, in which it is excluded that the floating mounted riser can tilt during operation of the sliding closure or during filling of the mold with molten metal.
  • the adjusting device is composed of two cooperating wedges and an actuating cylinder, wherein the one wedge on the casting furnace is mounted slidably in the middle of the riser and by the actuating cylinder in the direction of displacement of the sliding closure against the other attached to the riser wedge is pressed.
  • the attached to the riser wedge is screwed to a head portion of the riser.
  • actuatable by the actuating cylinder wedge is attached to push rods, which are guided in a seated on the casting support in the direction of displacement of the sliding closure.
  • the invention provides that the adjusting device is formed by a head part of the riser partially gripping arms and an actuating cylinder for the bracket, the latter being acted upon by the actuating cylinder in the direction of displacement of the sliding closure.
  • bracket is attached to push rods, which are guided in a seated on the casting support in the direction of the sliding closure.
  • the invention also provides that the actuating force of the actuating cylinder is precisely adjustable, so that the riser is not pressed too much when the Kippverriegelung takes effect.
  • the adjusting device is formed by two arranged on the riser diametrically to him and transverse to the direction of displacement of the sliding closure devices, each composed of a bolt attached to the head part of the riser and a cooperating with him stop, the is attached to a seated on the casting support.
  • the cylinder for moving the slide plate according to the invention designed such that it immediately in an unforeseen increase in the process of the same goes into a stop position, so that the riser is not placed in a tilting movement.
  • FIGS. 1, 2 and 5 show a casting installation for low-pressure casting of molten metal with a casting furnace 1, a casting mold 2 and a sliding closure 3 interposed in the working position.
  • the casting furnace 1 has a floating mounted riser 4, which is provided with a coronary head part 5.
  • a bellows 6 is provided for storage of the riser pipe 4.
  • the casting furnace 1 is equipped with an adjusting device 7 for the riser 4, by means of which it is locked during the filling of the mold 2 until after closing the sliding closure 3 against tilting.
  • the AnstellISS 7 is composed of two co-operating wedges 8a, 8b and an actuating cylinder 9, wherein the one wedge 8a on the casting furnace 1 is mounted centrally to the riser 4 slidably and by the actuating cylinder 9 in the direction 10 of the sliding closure 3 against the other on the riser. 4 attached wedge 8b is pressed. The latter is on the head part 5 of the riser 4, screwed.
  • the actuatable by the actuating cylinder 9 wedge 8a is attached to two parallel push rods 11a, 11b, which are guided in support strips 12a, 12b of a casting furnace 1 fixed to the carrier 13, in the direction 10 of the sliding closure 3.
  • the push rods 11a, 11b are interconnected on both sides by connecting strips 14a, 14b, one of which is fixed to the piston rod of the actuating cylinder 9, while on the other of the wedge 8a of the tilt lock is screwed.
  • the wedge 8a is pressed by the actuating cylinder 9 and the push rods 11a 11b against the other wedge 8b in the direction 10 of the sliding closure.
  • the operating force of the cylinder is sensitively adjusted.
  • the actuating cylinder 9 is automatically activated in operative connection with the operation of the sliding closure 3 during the casting process.
  • the bracket 15 is fastened to two parallel push rods 17a, 17b, which are guided in support strips 18a, 18b of a support 19 fastened to the casting furnace 1 in the displacement direction 10 of the sliding closure 3.
  • the push rods 17a, 17b are connected on both sides by connecting strips 20a, 20b, one of which is fixed to the piston rod of the actuating cylinder 16, while at the other of the bracket 15 of the tilt lock is screwed.
  • the bracket 15 is pressed by the actuating cylinder 16 against the head part 5 of the riser.
  • the actuating cylinder 16 is activated automatically similar to the actuating cylinder 9 of the embodiment of Figure 1.
  • the adjusting device 7 "by two on the riser 4 diametrically to him and transverse to the direction of displacement of the sliding closure 3 arranged devices formed, each consisting of a head part 5 of the riser 4 fixed bolt 21a , 21b and a cooperating with him stop 22a, 22b composed, which is screwed to a support 13 fixed to the casting furnace 1 with support strips 24a, 24b.
  • the bolts 21a, 21b are lowered when lowering the sliding closure 3 with the mold 2 against the head part 5 of the riser until they come against the stops 22a, 22b to stop and thus prevent the riser in the direction of displacement of the Tilt slide closure can.
  • the abutment surface of the stops 22a, 22b in the axial direction of the riser 4 is slightly bevelled from the outside inwards.
  • the cylinder for closing the slide plate of the slide fastener 3 is designed such that, in the event of an unforeseen increase in its force, it immediately moves into a stop position so that the riser pipe 4 is not set in a tilting motion.
