Abstract

PURPOSE:To improve the product precision, and also, to improve the yield by operating a secondary pressure means, only when the quantity of biscuits which remain behind in a sleeve at the time of filling a molten metal is within some prescribed allowable range. CONSTITUTION:When the first switch 17 is turned on, a timer of a controller is operated, and in case there is no input from the second switch 18 in a prescribed set time, a changeover valve 20 in a secondary pressure hydraulic circuit is switched. Subsequently, a secondary pressure cylinder 10 is operated by a speed which has adjusted stand-by pressure oil by a flow rate control valve 21, and pressure which has been adjusted by a pressure reducing valve 22. In case the first switch 17 is not operated, secondary pressure is not executed, and in case the second switch 18 has been operated within the set time, the secondary pressure is not executed as shortage of the quantity of a molten metal. In such a way, as for a filling defective, the secondary pressure is not executed and it is discharged, therefore, the precision of a product can be improved.
