Abstract

The invention discloses a cast sand core set for an integrated composite air cylinder cover. The cast 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 system sand mold. The temporary sand core set is formed by assembling an integrated bottom disc sand mold, a front sand mold, a rear sand mold, a right sand mold, a cam tappet sand mold and a left sand mold. A cylinder hole forming part for an air cylinder hole is integrated on the integrated bottom disc sand mold. The cylinder hole water jacket sand mold is integrated with a channel forming part used for forming a water feeding channel. The pouring system sand mold comprises a sprue, a main transverse pouring gate, two branched transverse pouring gates and a plurality of L-shaped inner pouring gates. The lower section part of the sprue is formed in the front sand mold, the upper section part of the sprue is provided by the pouring sand mold, the main transverse pouring gate is formed in the front end of the integrated bottom disc sand mold, the two branched transverse pouring gates are formed in the right sand mold, and the multiple L-shaped inner pouring gates are formed in the left sand mold. The sand core set is used for successfully casting the integrated composite air cylinder cover with the high component complex degree.

Description

technical field [0001] The invention relates to the field of foundry, in particular to a foundry sand core group of an integrated composite cylinder head. Background technique [0002] As a key component of a traditional internal combustion engine, the cylinder head, together with the cylinder block and cylinder liner, constitutes the core structure of the engine. The cylinder head is installed on the cylinder block, the cylinder liner is installed in the cylinder hole of the cylinder block, the cylinder head, the piston and the cylinder liner constitute the combustion chamber of the engine, and the piston reciprocates in the cylinder liner. In addition, the valve train, fuel injection system and cover are installed on the cylinder head. [0003] The traditional cylinder head is generally a web box-shaped structure, and the inner cavity is composed of air passages, valve installation structures, cylinder head bolt hole posts, injector hole seats, air hole posts and water ja...
