Definitions

the invention relates to a method for replacing a filter plate of a core shooting system, which forms the lower end of a sealing hood, under which, according to the process stages of core shooting, a gassing chamber and a core shooting chamber is inserted, with releasing a lock between the sealing cap and de filter plate, lifting the sealing hood of a dirty filter plate, lateral moving out of the gassing with overlying filter plate from the core shooting system, replacing the dirty filter plate against a cleaned filter plate, moving back the gassing with resting, cleaned filter plate in the core shooting system, lowering the sealing cap and locking the cleaned filter plate to the sealing cap ,
the invention relates to a core shooting machine having the features of the preamble of patent claim 2.
the invention has for its object to simplify the replacement of a dirty filter plate, so that the time and labor required thereby is reduced and the productivity of the core shooting system is increased accordingly.
the solution of this object is achieved according to the invention by a method having the features of claim 1.
this is proposed a core shooting system with the features of claim 2.
the core shooting installation 1 consists essentially of a molding box 2 with upper and lower mold part 3, 4, via which either a core shooting chamber 5 or a gassing chamber 6 is brought into position by a transverse movement corresponding to the working cycle of the installation.
a sealing means of a press unit 7 sealingly lowered onto it, down through a filter plate 8 closed sealing hood 9.
a in the sealing hood 9 opening compressed air tube 10 serves to pressurize the core shooting chamber 5 for injection of core sand into the molding box 2, previously on the hopper 11 has been filled with a sufficient amount of molding sand.
the core shooting chamber 5 along a transfer carriage 12 in their in Fig.1 and Fig.3 effectively shows position so that the Begasungshunt 6 enters between the sealing hood 9 and the molding box 2 and after sealing placing the sealing cap 9 gas can flow over the provided at her gassing tube 13 the molding box.
a pivotable plate holder 14 with three at an angle of preferably 120 ° to each other, fork-shaped plate receivers 15, 16 and 17.
the plate holder 15 is pivotable, so that passes through a pivoting movement, the soiled filter plate 8 from its horizontal position in an obliquely downwardly directed, easy access inclined position, so that access to it and thus a Exchange against a cleaned or new filter plate 8 is facilitated.
each fork-shaped plate holder 15, 16 or 17 each have a latch 19, 20 or 21.
a not shown, suitable rotary drive is coupled to the drive shaft 23 of the pivotable plate holder 14.
Fig. 4 The sequence of to be traversed for the exchange of a filter plate 8 movement phases is in Fig. 4 illustrated by the representation of the successive positions "a” to “n".
Starting from the position “a” takes place after position “b” lowering the sealing cap 9 and release the provided on the edge of the filter plate 8 lock 22.
position “c” the sealing cap 9 was lifted from the filter plate 8 so that they loose the gassing chamber 6 rests.
the gassing chamber 6 with the filter plate 8 lying on it has moved to the left towards the plate holder 14, so that the filter plate 8 comes into engagement with the plate holder 15 and locks 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 after "f" above the core box 2.
This allows a pivotal movement of the plate holder 14 such that the soiled filter plate passes by 120 ° in a downwardly directed, easy access inclined position, as shown in position "g".
the clean filter plate 8 kept in stock in the disk holder 17 pivots into the released horizontal transfer position, in which the gassing chamber 6 can enter under the filter plate 8, so that it reaches the position "h”.
Position "i" has been brought under the new, or cleaned filter plate 8 retracted gassing 6, so that the filter plate 8 rests on her.
the gassing chamber 6 moves back to the position "k” with the filter plate resting thereon.
