    • 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.
    • 一种用于铸造的金属模具装置,其适于防止铸造套筒掉落,并且在铸造套筒的内周壁和钻孔销的外周壁之间保持均匀的间隔。 在孔销的远端附近和孔的底端附近的外周部分上分别在孔销的外周部分上以规则的间隔在球孔的外周部分上设置球柱塞, 到孔销的轴向。 在孔销的前端附近的外周部设置有三个远端球塞,并且在其基端附近的外周部设置有三个基座球塞。 当沿轴向观察时,远端球柱塞与基座球柱塞异相60°。 此外,远端球塞设置在活塞环位于活塞的上止点位置附近的活塞环的区域。
