Abstract

The invention discloses a sand core set for casting an integrated composite cylinder cover. The sand core set comprises a temporary sand core set, a cylinder hole water jacket sand mold, a combined sand mold, a cover disc sand mold and a pouring sand mold; the temporary sand core set is formed by assembling an integral chassis sand mold, a front sand mold, a back sand mold, a right sand mold, a cam tappet sand mold and a left sand mold; the integral chassis sand mold is integrated with a cylinder hole molding part of a cylinder hole; a gap between the cylinder hole water jacket sand mold and the cylinder hole molding part of the cylinder hole is adjustable; the pouring sand mold includes a straight sprue, a main cross gate, two branch cross gates and multiple L-shaped ingates; the lower section part of the straight sprue is formed in the front sand mold, and the upper section part of the straight sprue is provided by the pouring sand mold; the main cross gate is formed in the front end of the integral chassis sand mold; and the two branch cross gates and the multiple L-shaped ingates are respectively formed in the left sand mold and the right sand mold. The sand core set is used for successfully casting the integrated composite cylinder cover with high part complexity.

Description

technical field [0001] The invention relates to the field of casting, in particular to a sand core group 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 wa...
