The position of the casting in the mold during pouring affects the quality, dimensional accuracy and difficulty of the casting process.
Selection principle of pouring position:
1. The important processing surface or main processing surface of the precision casting is facing down or on the side: when pouring, the gas, slag and sand in the mold will float up in the molten metal, which may cause pores, slag inclusions, etc. to appear in the upper part of the casting. Defects such as trachoma, and the possibility of defects in the lower part of the casting, the structure is denser.
a. The pouring position of the machine bed should face down the guide rail to ensure the quality of the important working surface. The quality requirements of the circumferential surface are relatively high, and the vertical pouring scheme can make the circumferential surface on the side, and the quality is uniform.
2. The large plane of the Precision Casting is poured downward or inclined: due to the strong thermal radiation of the hot metal liquid to the upper part of the mold during pouring, the top sand mold will expand and arch or even crack, causing sand inclusions, sand holes, etc. on the large plane. defect. The production casting defects of the large plane can be avoided by the method of casting the large plane downward or adopting the inclined pouring method.
3. The thin-walled part of the precision casting faces downwards, stands sideways or is inclined: in order to prevent the thin-walled parts of the castings from being cold and unable to be poured, the thin-walled part with a larger area should be placed at the lower part of the casting, or placed on the side wall or tilted position.
4. The thick part of the precision casting should be placed on the top or on the side of the parting surface. The main purpose is to facilitate the placement of the riser in the thick part for feeding.
