| PURPOSE: To improve the working efficiency and to simplify an equipment by returning back to a sand filling station separately from a mold box before removing the mold box to a send-out course after completing a sand compacting process to a filling frame in the method for forming a mold to the arrival mold box in order. CONSTITUTION: The empty mold box 6 is transported to the sand filling station 2 through a conveyor 4. A pattern plate holding body 11 is taken out from a rotary table 10 with an elevating table 8 and the mold box 6 is received from the conveyor 4 and successively, the filling frame 14 is received from a shifting device 13, the mold box with the pattern plate holding body and the sand filling flask, is shifted below a sand vessel. During filling the sand into the mold cavity part composed of the pattern plate holding body 11, mold box 6 and filling frame 14, the roller conveyor 4 and the holding member 13 are turned to the outer part and a molding sand compacting unit can again be descended on the rotary table 10. Based on the separating transportation of the filling frame 14 with the shifting device 13, since the separately molding works, in which the sand filling work is executed in the one side and the sand compacting work is executed in the other side, are simultaneously executed, the improvement of the molding efficiency is obtd.

| PURPOSE: To enable setting of a molding space in a titled device to be formed at an adequate scale by inserting squeezing plates into the space between top and bottom molding flasks which grasp matching plate from both sides and adjusting the insertion thereof. CONSTITUTION: While top and bottom molding flasks 16, 17 are in a station I , the flasks are moved forward from a retreat position by a mold moving device in proximity to each other so that a matching plate 27 is grasped from both sides. Squeezing plates 28a, 29a are fitted into the flasks 16, 17 by a fluid pressure cylinder device. The plates are moved to a set position while the position thereof is detected with detectors 32, 33 for the moving extent of the squeezing plates. The squeezing plates are stopped precisely in the intended position by a control device for movement of the squeezing plates. Molding sand is packed through introducing ports 43, 44 into the molding chamber by a supply device 38 for molding sand. The plate 29 is then advanced to compress the sand and thereafter a molding flask device 5 is turned to move the flasks 16, 17 to a rapping station II. COPYRIGHT: (C)1984,JPO&Japio | ||||||
