Definitions

  • the operating method of the apparatus 1 is shown step by step in FIG.s 5a to 5f and is characterized in that the empty molding boxes enter, one at a time, the filling station 8 along the input line 2 and exit after molding in the packing station 9 in order to advance directly along the output line 5.
  • a filling frame 12 is superimposed on an empty molding box 3'' which has not yet entered the filling station, while a molding box 3, which is already filled and coupled to a frame 12, is about to be transferred into the molding station 9.
  • a molded molding box 3' is unloaded in the molding station 9 onto the output line 5 and moves away from the apparatus.
  • the table 17 is lifted by the cylinder 18, placing the pattern plate 17' in contact with the molding box 3'', while, in the molding station, table 17' is lifted by the actuators 21 after moving the movable roller conveyors 23 mutually apart, placing the pack formed by the molding box 3 and by the frame 12 against the packing head 11.
  • FIG. 5d shows that in the filling station 8 the molding box 3'' is full while in the molding station 9 the molding box 3 is subjected to the injection performed by the head 11 and to the consequent packing of the sand.
  • FIG. 5e shows that in the filling station 8 the molding box 3'' has been filled and lowered after the movable roller conveyors 23 have been moved mutually apart. Simultaneously, in the molding station 9 the table 17' is lowered, moving the pattern plate 16 away from the molded molding box 3. During this step, the movable roller conveyors 23 are mutually closer, supporting the molding box 3 and separating it from the filling frame, which is moved by the transfer device in the direction of the arrow F.
  • FIG. 5f illustrates the final condition, in which in the filling station 8 the filled molding box 3'' is again motionless, while in the molding station the table 17' moves fully downward, placing the pattern plate 16 on the carousel 13. Simultaneously, the motion for transferring the frame 12 in the direction of the arrow T begins, while the molded molding box 3 is unloaded onto the transfer line 5. A new cycle begins at this point starting from the condition shown in FIG. 5a.
  • the method and the apparatus according to the invention allow to achieve molding capacities of more than 320 cycles/hour which are distinctly higher than those of conventional apparatus. In this manner, in a foundry, it is possible to use a single machine instead of two in order to meet high-productivity requirements.
