摘要： A metal mold device for casting that is adapted to prevent a casting sleeve from falling and that keeps even spacing between an inner circumferential wall of the casting sleeve and an outer circumferential wall of a bore pin. Ball plungers are provided at regular intervals in a circumferential direction on an outer circumferential portion of the bore pin in the vicinity of a distal end of the bore pin and on an outer circumferential portion in the vicinity of a basal end thereof, respectively, with respect to the axial direction of the bore pin. Three distal ball plungers are provided on the outer circumferential portion in the vicinity of the distal end of the bore pin and three basal ball plungers are provided on the outer circumferential portion in the vicinity of the basal end thereof. The distal ball plungers are 60° out of phase with the basal ball plungers when viewed in the axial direction. Further, the distal ball plungers are provided in an area where a piston ring, in the vicinity of a top dead center position of a piston, is located.

摘要： The object of the present invention is to provide a casting method capable of simultaneously attaining the shortening of cycle time and the improvement in casting quality.The pressure allowing the molten metal level to go up to the positions of from P0 to P4 is applied to the molten metal within a molten metal reservoir 1. Then, the pressure of P4 is maintained for a predetermined time. During this time, the molten metal which comes into contact with an upper die 4 is cooled earlier than the molten metal being in contact with another die. Through this cooling the molten metal shrinks. However, since the pressure of P4 is maintained, the molten metal is supplied from the lower side to a shrunk portion, so as not to cause shrinkage cavity or underfill.
