Abstract

The invention discloses a manufacture method of a water-oil pipeline casting mould and a water-oil pipeline of a diesel engine machine body. The manufacture method includes the following steps that a,a water channel and water cavity combined sand core is manufactured, two L-shaped steel pipes (1) are welded in a positioning mould sample, the two L-shaped steel pipes (1) are filled with first heat-resistant paint coatings (11), flexible exhaust pipes (12) are placed in gaps in the two L-shaped steel pipes (1), blasting fuses (13) are placed in the flexible exhaust pipes (12), then, the L-shaped steel pipes (1) are filled with zircon powder resin sand (14), and a water channel mud core assembly is formed; and b, the water channel mud core assembly is placed in a water cavity core box, the positioning position of the water channel mud core assembly is filled with furan resin sand (2), and the flexible exhaust pipes (12) penetrate out from the furan resin sand (2). By means of design methods such as usage of the water pipe heat-resistant coatings and heat-resistant sand and a certain period time of baking at a certain temperature, the problems that foundry sand in the pipes is sintered and iron burnt-on sand is formed on the inner walls of the pipes and cannot be removed are solved.

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 weldi...
