Abstract

The invention discloses an automobile engine cylinder cover and a manufacturing method thereof. The automobile engine cylinder cover is a product prepared by the following raw materials and the manufacturing method, and comprises the raw material composition by weight: 90% of gray iron cuttings, 10% of casting roughing sand, 5% of a furan resin, and 1.0% of a curing agent. The method has the beneficial effects of effectively preventing generation of defects of casting shrinkage cavities, shrinkage porosity, deformation and cracks.

Description

technical field [0001] The invention relates to the field of automobile engine manufacturing, in particular to an automobile engine cylinder head and a manufacturing method thereof. Background technique [0002] The engine cylinder head plays a very important role in the entire engine system. It is an important structural component of the internal combustion engine. Its function is to seal the cylinder and form the combustion chamber. material requirements. The traditional automobile engine cylinder head is made of high-strength die-casting aluminum, but the production cost of die-casting aluminum is high, and the tensile strength and wear resistance of the cylinder head are not as superior as cast iron QT600-3, so cast iron QT600-3 is still used for large displacement . [0003] The engine cylinder head is a typical thin-walled complex casting, and the final pass rate of this type of casting in many factories is only about 50%. The reason for this situation is mainly rel...
