摘要： A process for manufacturing a siamese-type clyinder block which is disclosed herein comprises a blank making step of providing a cylinder block blank in which a sleeve made of a cast iron is cast in each cylinder barrel of a siamese-type barrel made of an aluminum alloy and consisting of a plurality of cylinder barrels connected in series, and a mechanically working or machining step of forming the inner peripheral surface of each sleeve of the cylinder block blank into a true circle. The process is characterized in that the blank making step includes placing highly rigid sleeves each having a thickness set as large as 10% or more of the inner diameter thereof into a siamese-type cylinder barrel molding cavity in a mold and then pouring a molten metal of aluminum alloy under a pressure into the cavity to effect a casting. The sleeve is cast-in as it is at an ambient temperature or in a heated state. A cylinder block blank resulting from the casting-in of sleeves at an ambient temperature is subjected to a thermal treatment for reducing the casting strain in each cylinder barrel.
摘要翻译：一种本文公开的暹粒型煤渣块的制造方法包括坯料制造步骤，该坯料制造步骤提供一种气缸体坯料，其中由铸铁制成的套筒铸造在由铝制成的暹罗型桶的每个气缸筒中合金，并且由串联连接的多个缸筒组成，以及将气缸体坯料的每个套筒的内周面形成为真圆的机械加工或加工步骤。该方法的特征在于，坯料制造步骤包括将具有设定为其内径的10％或更多的厚度的高度刚性的套管放置在模具中的暹粒型缸筒模制腔中，然后将熔融金属的铝合金在压力下进入腔体进行铸造。套筒在环境温度或加热状态下被铸造。在环境温度下由套管浇铸而产生的气缸体坯料经受热处理以减少每个气缸筒中的铸造应变。

摘要： A siamese-type cylinder block blank which is composed so that upon the pouring a molten metal under a pressure, a sleeve of cast iron is cast in each cylinder barrel of a siamese-type cylinder barrel made of an aluminum alloy and consisting of a plurality of cylinder barrels connected in series. The cylinder block blank is characterized in that each sleeve cast presents a substantially oval configuration in section with the lengthwise axis parallel to the direction of cylinder barrels arranged, as a result of the reception of the solidification shrinkage force of each cylinder barrel.

摘要： A body frame for a motor bicycle includes a main frame, a head tube provided at a front end of the main frame and down tubes extending rearward from the main frame. The main frame, head tube and down tubes are cast with a light alloy into an integral form of a hollow and thin-wall structure. A production process of the body frame, wherein an integrally-formed core, which is formed into a shape similar to that of the body frame, is hollow and has good permability. A molten metal is charged into the mold and a vacuum is applied to the interior of the core. The molten metal is charged into a cavity defined between the core and the molding surface of the mold by a low-pressure casting method, and the molten metal is solidified so as to cast the body frame. A production apparatus of the body frame includes a liftable cope fitted to a vertical casting machine, a fixed drag, and slidable molds disposed in combination with the cope and being capable of horizontally sliding in a state that the cope is released from the drag. A body frame having both properties of light weight and high stiffness, and a production process and apparatus thereof is provided wherein casting defects and to provide a high-precision cast article, is provided.
