The present invention relates to a mold molding apparatus used on a casting line, and a method for controlling the mold molding apparatus.
Generally, a casting procedure includes a sand treatment step, a mold molding step, a core installation step, a melt pouring step, a cooling/conveying step, and a post-treatment step. For performing these steps, a sand treatment apparatus, a mold molding apparatus, a core installation apparatus, a melt pouring apparatus, a cooling/conveying apparatus, and a post-treatment apparatus are respectively provided in the order of the steps.
The present invention is directed to a mold molding apparatus provided for the mold molding step.
FIG. 1 is a vertical section view of a mold molding apparatus according to a first embodiment of the present invention.
FIG. 2 is a vertical section view showing the above-mentioned first embodiment in a state in which the mold molding space has been delimited.
FIG. 3 is a vertical section view showing the above-mentioned first embodiment in a molding sand squeezed state after the molding sand has been loaded.
Hereinafter, embodiments of the present invention will be explained in detail by referring to the drawings.
FIG. 1 is a vertical section view of a mold molding apparatus 100 according to the present invention. In this drawing, frame setting cylinders 102, 102 are installed so as stand on both the left and right sides above a molding base 101, and a raising/lowering support frame 103 is arranged to span the tips of piston rods 102A, 102B of the frame setting cylinders 102, 102. In other words, the frame setting cylinders 102, 102 stand upright with the retracted ends towards the molding base 101.
Below one (the left side in FIG. 1) of the frame setting cylinders 102, 102, a central portion of a pattern exchange apparatus 104 is supported so as to be able to rotate in the horizontal plane. On both ends of the pattern exchange apparatus 104, pattern carriers 106, 106A, on which pattern plates 105, 105A (upper and lower pattern plates) are placed, are set in a state such that they are lifted up by approximately 5 mm by means of springs (not illustrated). The pattern plates 105, 105A are conveyed, in alternating fashion, into and out of an area above the center of the molding base 101.
