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 permeability. 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, and 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 are obviated a high-precision cast article, are provided.

摘要： An evaporative pattern casting process includes forming a mold by burying a pattern made of resin foam in casting sand, pouring molten metal into the mold, and evaporating the pattern with the molten metal and thereby casting a product. In the evaporative pattern casting process, casting time during founding is set according to a modulus (pattern volume÷pattern surface area) of the pattern. Accordingly, the casting time in the evaporative pattern casting process is accurately set with high precision.

摘要： A heated state-deciding apparatus and a thermocouple provided for a transport robot for detecting the temperature of a billet being transported by the transport robot, and a deciding member for deciding whether or not the billet is heated to be in a predetermined solid phase state on the basis of the detected temperature. Accordingly, it is possible to efficiently and accurately decide whether or not the solidus rate of the metal billet is good or bad, and it is possible to improve the productivity.
