Engine block core assembly process, engine block sand core and sand core set

Abstract

The invention discloses an engine cylinder sand core, which comprises a main body end core and a process core. The non-sand hole end matches the core assembly. When applying the engine cylinder sand core provided by the present invention, the water jacket core with sand outlet holes at the front and rear ends can be combined with the water jacket core without sand outlet holes at the front and rear ends through the classification of the main body end core and the process core. The core process is common, and only one production line can meet the core assembly requirements for water jacket cores with sand outlet holes and water jacket cores without sand outlet holes, thus reducing the number of core assembly steps and improving the core wire quality of the engine cylinder body Flexibility and degree of automation. The invention also discloses a sand core group of the engine cylinder body and a core assembly process of the engine cylinder body.

Description

technical field [0001] The invention relates to the field of casting technology, more specifically, to an engine cylinder sand core, an engine cylinder sand core set, and an engine cylinder core assembly process. Background technique [0002] The cylinder block of the engine is generally produced by casting process. In foundry production, sand cores are used to form the cavity of the casting. The commonly used engine block casting process in the prior art mostly adopts the method of core casting. Engine cylinder sand core sets generally include water jacket cores, end cores, cap cores, box cores, etc., and each sand core is cored before pouring. [0003] According to different cylinder structures and process requirements, the water jacket core of the engine block includes the water jacket core with sand holes at the front and rear ends and the water jacket core without sand holes at the front and rear ends. Due to the different structures of the water jacket cores, it is ...
