摘要： A casting die assembly which does not produce any burrs includes a stationary die and a movable die that are clamped in a condition in which a slide core is caused to move toward a center of a movable die, and a back surface of a protrusion of the slide core contacts a stopper section provided on a frame section. The stopper section is subjected to the pressure applied to the slide core during a casting operation. Since the stopper section is provided on part of the frame section, which is integrally formed on the periphery of the stationary die, the stopper section is not caused to retreat or deform by the casting pressure and as a result, the slide core is not moved and burrs are not produced.

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.

摘要： Four cavities are arranged on a concentric circle “C” with respect to the center “O” of a flow divider and a gate sleeve. Each of the cavities is connected to a sleeve stamp portion through each of four die side runners and each of four stamp side runners formed in a radial direction and separated from the neighboring runners. A semicircular arc-shaped reservoir is provided between the lower half side of the flow divider and the lower half side of the gate sleeve. This reservoir is connected to the sleeve stamp portion. A semi-solidified layer formed by pouring the molten metal into a sleeve is filled into the reservoir, so that the molten metal from which the semi-solidified layer is separated can be filled directly from each of the stamp side runners via the die side runners into each of the cavities evenly and simultaneously.

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.
