    摘要： A casting mold includes a cavity formed therein, and an auxiliary mold projecting into the cavity. The auxiliary mold forms a concave portion in a cast product, and it exhibits a thermal expansion coefficient being more than a thermal expansion coefficient exhibited by a molten metal to be charged into the cavity. Hence, the auxiliary mold greatly expands thermally during casting, and it keeps the expanded state during the solidification of the molten metal. Accordingly, the casting mold can prevent the casting defects resulting from the shrinkage cavities from arising in the resulting cast products. All in all, the casting mold can obviate to give the auxiliary mold a tapered configuration, and it can reduce the after-casting machining allowance to be provided in the resulting concave portion.

    摘要翻译： 铸模包括形成在其中的空腔和突出到空腔中的辅助模具。 辅助模具在铸造产品中形成凹部，并且其展现的热膨胀系数大于被填充到空腔中的熔融金属所表现的热膨胀系数。 因此，辅助模具在铸造过程中大大地膨胀，并且在熔融金属固化期间保持膨胀状态。 因此，铸模可以防止在所得铸造产品中产生由于收缩腔产生的铸造缺陷。 总而言之，铸模可以避免给予辅助模具锥形构造，并且可以减少在所得凹部中提供的后铸加工余量。

    摘要： A process for casting a pipe such as a delivery pipe with transversal holes, the pipe having an elongate longitudinal hole and at least one pair of transversal holes communicating with the longitudinal hole in a substantially normal direction thereto. The process comprises the steps of positioning a rod-like center pin for forming the longitudinal hole in a predetermined positional relation to a cavity formation surface of a casting die, positioning a pair of mandrel pins for forming the pair of transversal holes such that end faces thereof are in contact with side surfaces of the center pin, and charging molten metal into a die cavity after the center pin and the pair of mandrel pins have been positioned. The molten metal is charged under the condition that the center pin is prevented from deforming by the pair of mandrel pins.

    摘要： A cavity defined by a casting mold is filled with a molten metal in such a condition that a sliding member movable forward and rearward has been moved into the cavity. The sliding member is drawn out of the cavity when the molten metal solidifies to such a degree as to maintain a certain shape. A separate member to be force-fitted is placed between the distal end of the sliding member and the cavity. The sliding member is then advanced into the cavity so that the separate member is force-fitted into a concave portion formed in the casting before the casting mold enclosing the casting is opened. The separate member is thus force-fitted into the casting while the casting is enclosed in the casting mold.

    摘要翻译： 由铸模限定的空腔以熔融金属填充，使得可向前和向后移动的滑动构件已经移动到空腔中。 当熔融金属凝固到保持一定形状的程度时，将滑动构件从空腔中拉出。 将被强制装配的单独构件放置在滑动构件的远端和空腔之间。 然后将滑动构件推进到空腔中，使得在封闭铸件的铸模打开之前，单独的构件被力配合到形成在铸件中的凹部中。 因此，将铸造件封闭在铸模中时，将单独的构件强制配合到铸件中。
