Abstract

The invention discloses a casting method of a flywheel shell with a gear chamber cover. The method comprises following steps of core manufacturing, wherein a chassis core, a lower frame core, an upper frame core, riser cores, a flywheel shell core, a gear chamber cover core and a pouring cup core are manufactured, an arc transverse pouring gate is arranged on the top face of the chassis core, and a plurality of inner pouring gates extending to the center from the transverse pouring gate are arranged on the inner side of the transverse pouring gate; sand milling, wherein the flywheel shell core and the gear chamber cover core are subject to sand milling machining; core assembly; pouring; cooling; and cleaning. Sand boxes, molds and appearances are not needed, positioning of the multiple sand cores is achieved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the casting field, in particular to a casting method of a flywheel housing with a gear chamber cover. Background technique [0002] Diesel engine flywheel housing and gear chamber are important parts of diesel engine. They are installed between the engine and gearbox, externally connected to crankcase, starter, oil pan, and built-in flywheel assembly, which play the role of connecting the body, protection and carrier. [0003] The casting of the traditional aluminum alloy flywheel housing usually needs to make the sand core and shape through the mold first, and then obtain the casting mold through the assembly of the sand core, box closing, etc., and then pour the aluminum liquid, and obtain the casting after cooling. [0004] At present, the development of diesel engines tends to be lightweight and intensive, so the aluminum alloy flywheel housing with gear chamber cover structure is also designed and developed accordingly.
