Title: Suction casting method
Inventor: HORINO TADAHIRO
IPC: B22D18/08
Filed: 1988-11-24
Abstract: PURPOSE:To easily decide whether good or bad filling into a suction casting product by directly detecting the time from starting filling of molten metal in a sprue part to reaching of the molten metal to a chilling plate pushed against upper part of a gypsum mold and deciding that it is the bad filling when the filling time of the molten material is out of the prescribed filling time. CONSTITUTION:Pressure in a cavity 14 is reduced through jointing face of the gypsum mold 6 and the chilling plate 9. Then, in order to fill up the molten metal 24 into the cavity 14, the sprue part 8 in the mold 6 is dipped into a molten metal furnace 23 and the molten metal 24 is sucked. At the same time of this, the time from filling start of the molten metal from the sprue part 8 to reaching of the molten metal to the chilling plate 9 is directly detected with an insulated sensor 27. Then, the filling time detected with the sensor 27 is compared with the preset prescribed range of filling time, and when the actual filling time is out of the prescribed range of filling time, this is decided as the bad filling and whether the good or bad casting product can be easily decided.
