摘要： A molten metal supply device capable of supplying molten metal with high precision to an injection sleeve of a die-casting machine, and capable of reducing molten metal leakage and damage to a molten metal conduit bridging between a holding furnace and the injection sleeve. The holding furnace is divided into a holding chamber and a supply chamber in fluid connection with the injection sleeve through the conduit. Both chambers can be selectively brought into and out of fluid connection by a stopper. First and second immersion bodies are immersibly provided to the chambers, respectively. The laser sensor detects a predetermined level of the molten metal. The first immersion body is immersed until the sensor detects the surface of the molten metal, whereupon the stopper blocks fluid communication between the chambers. By then lowering the second immersion body, molten metal is pushed out of the supply chamber and a predetermined amount of molten metal is supplied to the injection sleeve. The conduit includes a duct and a mouthpiece, The duct is provided by an inner ceramic layer, an outer stainless steel tube, a heat line wound over the stainless steel tube, and a mortar layer.

摘要： A cylinder liner or a cylinder block's bore portion formed of a composite alloy material reinforced with fibers and dispersed with ceramic particles. In the cylinder liner or the bore portion of the cylinder block, ceramic particles and alumina short fibers are uniformly dispersed in a light metal matrix. For producing the cylinder liner and the cylinder block, a preform having a shape identical with the cylinder liner or the bore portion is produced by mixing together the ceramic particles and the alumina short fibers. Molten light metal is infiltrated into voids of the preform during casting.

摘要： A closed deck type cylinder block providing an optimum area ratio of opening at a top deck side, and a method for producing such cylinder block having the reduced area ratio of the opening at a reduced energy cost and with reduced labor, yet exhibiting smooth discharge of waste sand converted from a water jacket core through the opening in spite of the reduced area ratio of the opening. The cylinder block is formed with a plurality of cylinders juxtaposedly arranged to each other and a water jacket portion surrounding the cylinders. An upper end of the water jacket portion is open at a top deck and is partly covered with bridge portions. The opening has an area ratio of from 10 to 30% of a projection area of the water jacket portion at the top deck surface.

摘要： A metal mold arrangement for producing a closed deck type cylinder block in which a plurality of bridge portions partly cover an open end of a water jacket at a top deck side of the cylinder block. A water jacket die provides a configuration of a water jacket. A plurality of recesses are formed in the water jacket die, and each separate core having a shape complementary to the recess is insetted in each recess. Each separate core has a top deck side end face and a crank case side end face opposite thereto. The two faces are slanted in a direction opposite to each other for serving as drafts. A bottom of each recess is also slanted coincident with the slant of the top deck side end face, and each bridge portion is formed adjacent the bottom of the recess. Upon solidification of a molten metal, the water jacket die is removed from the casted product while each separate core remains in a resultant water jacket. Each of the separate core can be moved toward a direction to increase a distance between the end faces within the water jacket and can be offset from each bridge portion, thereby removing the separate core from the water jacket.
摘要翻译：一种用于生产封闭甲板型气缸体的金属模具装置，其中多个桥接部分部分地覆盖在气缸体的顶部甲板侧的水套的开口端。水套模具提供水套的构造。在水套模具中形成多个凹部，并且在每个凹部中插入具有与凹部互补的形状的每个分离的芯部。每个单独的芯具有顶面侧端面和与其相对的曲轴箱侧端面。两个面相互倾斜的方向倾斜以作为牵伸。每个凹部的底部也与顶部甲板侧端面的倾斜一致倾斜，并且每个桥接部分邻近凹部的底部形成。在熔融金属凝固时，将水套管模从铸造产品中移出，而每个分离的芯保留在所得的水套中。每个分离的芯可以朝向增加水套之间的端面之间的距离的方向移动并且可以从每个桥接部分偏移，从而从水套除去单独的芯。
