Definitions

  • the invention relates to a core shooting range with the features of the preamble of claim 1 and a method for exchanging a filter plate of a core shooting range with the features of the preamble of claim 5.
  • Such a core shooting range and such a method for exchanging a filter plate of a core shooting range is known, for example, from US Pat CN 2 701 552 Y known that describes a filter changing device with a filter plate holder.
  • the filter plate mentioned also referred to as a shooting sieve
  • the filter plate mentioned has to be exchanged for a cleaned filter plate after every hour, for example.
  • operating personnel must be available at the appropriate time to remove the dirty, relatively heavy filter plate from lift off the extended fumigation chamber and replace it with a cleaned filter plate. Due to the design height of the machine, this must be done in an unfavorable position for handling. In addition, this takes around 5 minutes each, so that the effective operating time of the core shooting range is limited accordingly.
  • the invention has for its object to simplify the replacement of a dirty filter plate, so that the time and effort involved is reduced and the productivity of the core shooting range is increased accordingly.
  • This object is achieved according to the invention by a core shooting range with the features of claim 1.
  • a method for replacing the filter plate (8) of the core shooting range with the features of claim 5 is proposed.
  • the core shooting system 1 essentially consists of a molding box 2 with an upper and lower molding 3, 4, via which a core shooting chamber 5 or a gassing chamber 6 is brought into position by a transverse movement in accordance with the working cycle of the system. Above this is a sealing hood 9, which can be lowered onto it by means of a pressing unit 7 and is closed at the bottom by a filter plate 8 the hopper 11 has been filled with a sufficient amount of molding sand.
  • the core shooting chamber 5 is inserted into its in along a transfer carriage 12 Fig.1 and Fig.3 shown position retracted so that the gassing chamber 6 between the sealing hood 9 and the molding box 2 retracts and gas can flow to the molding box via the gassing pipe 13 provided thereon after sealing the sealing hood.
  • a pivotable plate holder 14 with three fork-shaped plate receptacles 15, 16 and 17 arranged at an angle of preferably 120 ° to one another is provided on the side of the core shooting range 1.
  • a first plate holder 15 is located at the beginning of the exchange of a dirty filter plate 8 in a plane parallel to the transfer carriage 12, so that the filter plate 8 can be transferred to the plate holder 14 or inserted into a plate holder 15 by the movement of the gassing chamber 6 .
  • the plate holder can be pivoted, so that the contaminated filter plate 8 moves from its horizontal position into an obliquely downward, easily accessible inclined position by means of a pivoting movement, so that it can be accessed and thus Exchange for a cleaned or new filter plate 8 is facilitated.
  • this pivoting movement brings a filter plate 8 held in stock in another (17) of the three plate receptacles 15, 16 and 17 into the position in which the soiled filter plate 8 was previously, so that it was immediately taken up again by the core shooting system can be.
  • Each fork-shaped plate receptacle 15, 16 or 17 has a latch 19, 20 or 21.
  • a suitable rotary drive (not shown) is coupled to the drive shaft 23 of the pivotable plate holder 14.
  • FIG Fig. 4 The sequence of the movement phases to be passed through to replace a filter plate 8 is shown in FIG Fig. 4 illustrated by the representation of the successive positions "a” to "n".
  • the sealing hood 9 is lowered and the locking device 22 provided on the edge of the filter plate 8 is released.
  • the sealing hood 9 was lifted off the filter plate 8 so that it loosely opened the fumigation chamber 6 rests.
  • the gassing chamber 6 with the filter plate 8 lying there has been moved to the left to the plate holder 14, so that the filter plate 8 comes into engagement with the plate holder 15 and latches there with the pawl 19.
  • position "e the gassing chamber 6 has lowered so that it has lost contact with the filter plate 8.
  • the gassing chamber 6 can move back to the position “f” above the core box 2. This enables a pivoting movement of the plate holder 14 in such a way that the soiled filter plate passes through 120 ° into a downward, easily accessible inclined position, as shown in position "g".
  • the clean filter plate 8 kept in stock in the plate receptacle 17 pivots into the freed-up horizontal transfer position, in which the gassing chamber 6 can move under the filter plate 8, so that it reaches the position "h”.
  • Position "i” the gassing chamber 6 moved under the new or cleaned filter plate 8 has been raised so that the filter plate 8 rests on it.
  • the gassing chamber 6 then moves back to the "k” position with the filter plate lying on top.
