Summary:PURPOSE:To facilitate deflashing and coating of a parting material by mounting a die for molding a water jacket to the upper die of a casting device and advancing and retreating an insert pin for mounting a sleeve independently from the die. CONSTITUTION:The die 11 for molding a water jacket which is hung by a holding block 10 is fixed to the rear surface of the upper did 4 of the cylinder block casting device. The insert pin 12 is inserted into the space enclosed by the die 11 so as to come into sliding contact with a thick part 11a of the die 11. The sleeve 13 is mounted onto the outside circumference of the insert pin 12 and right and left middle dies 3, 4 and the upper die 4 are clamped. A molten metal is packed into a cavity 2 in the state of lowering the insert pin 12 to the lowermost position. The air intruding in the cavity 2 or between the insert pin 12 and the sleeve 13 is discharged through a V-groove 17 formed to the insert pin 12. The die life is thereby improved and the quality around the sleeve is improved.
