Abstract

The invention discloses a pouring device for casting an integrated composite air cylinder cover. The integrated composite air cylinder cover comprises air inlet ducts, air exhaust ducts, oil atomizer mounting holes, cylinder cover upper water jackets, cylinder cover lower water jackets, air cylinder holes, cylinder hole water jackets and cam tappet holes. The pouring device is used for casting the integrated composite air cylinder cover. The pouring device comprises a straight sprue runner, a main cross sprue runner, two branch cross sprue runners and a plurality of L-shaped inner sprue runners; the straight sprue runner is arranged vertically; a sprue cup is arranged at the upper end of the straight sprue runner; filter screens are arranged at the two ends of the main cross sprue runner; the bottom end of the straight sprue runner communicates with the main cross sprue runner; the two branch cross sprue runners are arranged in parallel; slag collection bags are arranged at the other ends of the two branch cross sprue runners respectively; the L-shaped inner sprue runners are uniformly arranged on the inner sides of the two branch cross sprue runners; an outlet end of each L-shaped inner sprue runner is in a gradually-reducing shape; and the L-shaped inner sprue runners are used for guiding molten metal into casting moulds. The pouring device can successfully cast the integrated composite air cylinder cover high in part complexity.

Description

technical field [0001] The invention relates to the field of casting, in particular to a pouring device for casting an integrated composite cylinder head. Background technique [0002] As a key component of a traditional internal combustion engine, the cylinder head forms the core structure of the engine together with the cylinder block and cylinder liner. The cylinder head is installed on the cylinder block, and the cylinder liner is installed in the cylinder bore of the cylinder block. The cylinder head, piston and cylinder liner form the combustion chamber of the engine, and the piston reciprocates in the cylinder liner. In addition, the gas distribution mechanism, fuel injection system and cover are installed on the cylinder head. [0003] The traditional cylinder head is generally a plate-shaped box-like structure. The inner cavity is composed of air passages, valve mounting structures, cylinder head bolt hole columns, fuel injector hole seats, air hole columns and wat...
