Abstract

The invention discloses a casting mold for a water-oil pipeline of a diesel engine fuselage and a method for making the water-oil pipeline. , fill the first heat-resistant paint coating (11) in the two L-shaped steel pipes (1), and place a flexible exhaust pipe (12) in the gap in the two L-shaped steel pipes (1), the flexible exhaust pipe The fuse (13) is placed in (12), and then the L-shaped steel pipe (1) is filled with zircon powder resin sand (14) to form the water channel core assembly; (b) put the water channel core assembly into the water In the cavity core box, furan resin sand (2) is filled in its positioning position, and the flexible exhaust pipe (12) passes through the furan resin sand (2). The invention solves the problem of sintering of molding sand in the pipe and formation of iron-adhesive sand on the inner wall of the pipe that cannot be cleaned through design methods such as the use of heat-resistant coating and heat-resistant sand for water pipes and baking at a certain temperature and time.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a casting mold for a water-oil pipeline of a diesel engine body and a method for manufacturing the water-oil pipeline. Background technique [0002] Large diesel engines are mainly used in the shipbuilding industry as the main power of ships. With the rapid development of the nuclear power field in recent years, the demand for large diesel engines for emergency power generation of nuclear power units has been strong. In addition, large diesel engines in overseas markets are used for land fixed power generation and mobile power generation. The demand is also increasing year by year. [0003] The casting technology of large-scale high-toughness diesel engine fuselage is very difficult, and requires high technology, raw materials, equipment and personnel. Diesel engine fuselages at home and abroad have always been produced in two forms: casting and welding, and welding...
