Definitions

  • the invention has for its object a method and a device for performing the method and to propose a suitable casting mold, which allow the expenditure on equipment and thus the investment costs to keep comparatively low, which is a low one Maintenance effort with high process reliability and require precise repeatability and quantity significantly reduce the amount of circulatory material, save energy, avoid smoke, a height dependent Exclude penetration formation and beyond ensure a calm, turbulence-free mold filling.
  • Another concern of the invention is that Design the casting machine so that existing casting machines are also available can be retrofitted in a simple and cost-effective manner can, so that the inventive method on this Casting plants is feasible.
  • the Filling line is connected to a casting machine and in lower part of a pressure chamber ends.
  • these lower ones Part of the pressure chamber can also be a feed chute ends whose filling funnels are not closed must, if this is above the maximum filling level of the Pressure vessel.
  • Such a potting machine allowed it, by increasing the pressure in the pressure vessel the filling pressure to gradually increase according to the respective Requirements, so that the mold cavity without any risk of penetration and can be filled without turbulence.
  • Two or more filling lines can be connected to a casting machine can be connected, allowing multiple molds at the same time can be filled.
  • the casting plant for the implementation of the invention The method consists of a transport device for the Delivery and removal of the mold boxes, a casting machine for filling the mold boxes and a shut-off device for blocking the pouring channel of the mold after the casting has taken place, the transport device providing a Transfer carriage contains, by means of which the molding box transverse to the transport direction of the transport path to the casting machine can be moved back and forth to the transport track, by the displacement of the mold box this tight against an opening of a filling line of the casting machine is movable and the metal by means of the casting machine by means of the overpressure in the mold cavity of the casting mold is impressible.
  • the casting machine is advantageously a those that have a pressure vessel, in the lower Area both the filling line and a filling shaft ends, recharged over the material in the casting machine becomes.
  • the pressure vessel is closed and on a compressed gas system connected so that when increasing the Pressure in the pressure vessel the material in the filling line like also rises in the feed chute. Since the feed chute with a pouring funnel that is above the maximum The level of the pressure tank is above and above the mouth of the filling line, it is possible the casting machine recharge at any time.
  • 1 denotes the standing track on the molding boxes 2 can be transported by means of a trolley 3.
  • the Transport trolley 3 runs with its wheels 3 'on rails 4, a section of the rails 4 is on a transfer carriage 5 arranged, which in turn provided with wheels 6 is, which run on rails 7, which are transverse to the rails 4 of the lane 1 extend.
  • the transfer vehicle is driven 5 through a double-acting piston-cylinder unit 8th.
  • a channel 19 is formed in the upper half of the mold 11, which is at a short distance from the pouring channel 14 ends.
  • a stamp 20 of a locking cylinder can be inserted into this channel 21 are introduced, the sand between the End of the channel 19 and the pouring channel 14 so displaced that this sand closes the pouring channel 14.
  • the pressure vessel In the lower area the pressure vessel is on the one hand with a Filling line 28 and on the other hand with a filling shaft 29 connected.
  • the feed chute 29 ends in a pouring funnel 30, its opening both above the pressure vessel 23 and above the mouth 31 of the filling line 28 ends.
  • the filling line 28 is essentially in its upper part horizontally formed and ends here in a head channel 32, which is completed on all sides. This head channel can be provided with a closable opening to be able to clean it better if necessary.
  • the potting machine 22 has an induction heater 33, with which kept the melt 27 at the casting temperature becomes.
  • the casting machine 22 is equipped with wheels 34, which run on rails 35 so that the potting machine at Can also be moved to a refill.
  • the casting plant according to the invention works as follows:
  • the molds are placed on the with their mold boxes Stand 1 transported in the direction of arrow 37 and arrive in cycles with their trolleys 3 on the transfer car 5.
  • This transfer carriage is then by means of the piston-cylinder unit 8 in the direction of arrow 39 postponed until the mouth 31 of the filling line 28 bears against the contact surface 16 of the casting mold 11.
  • the piston-cylinder unit 8 with such Pressure is applied to a given contact pressure between the mouth 31 and the contact surface 16 sets.
  • compressed gas is supplied via the Blown compressed gas port 25 into the pressure vessel 23, and until the level of the molten metal in the Filling line 28 via the mouth 31 into the pouring channel 14 the mold 11 runs.
  • the Pressure increased until the specified filling pressure for the mold 11 is obtained. This pressure is over the total filling time of the mold cavity 13 of the casting mold 11 maintained, although it is also possible depending the mold cavity 13 a certain pressure profile at Filling to drive.
  • the mold 11 is this provided with a ventilation channel 40 through which Gas contained in the mold cavity can escape.
  • This vent channel is not, however, compulsory, it can then omitted if the mold as such is sufficient is gas permeable for the filling process.
  • the stamp 20 is removed by means of the Locking cylinder 21 retracted into the channel 19, the Sand is shifted in such a way that the pouring channel 14 closes.
  • the mold box with the mold 11 immediately return to its starting position be, so that in cycle operation another Mold box of a mold 11 positioned on the transfer carriage 5 can be.
  • the pouring process described is repeated then.
  • FIG. 3 shows the previously described filling process and molded box with the casting mold moved into the filling position 11.
  • Fig. 3 shows how the increased pressure in the pressure vessel 23 affects, this pressure being increased so far can, as is the pouring funnel 30 of the filling shaft 29 permits.
  • the embodiment shown in FIGS. 5 and 6 differs from that in the previous ones Fig. Alone that the mold 11th including the molding box 2, the trolley 3 and of the sliding carriage 5 by an angle ⁇ to the horizontal have been tilted. This also presupposes that the head canal 32 of the filling line 28 is formed accordingly obliquely is, so that the mouth 31 of the filling line 28 on the contact surface 16 of the pouring channel 14 is obtained.
  • Fig. 6 shows that compared to Fig. 5 for the potting machine 22 moved mold box 2 with the mold 11 as well as the bath level inside the casting machine 22.
