铝合金缸盖低压铸造模具设计及凝固质量优化
Design of Low Pressure Casting Mold for Aluminum Alloy Cylinder Head and Optimization of Solidification Quality
摘要
Abstract
To solve the defects of aluminum alloy single cylinder head of motorcycle engine,such as dispersed shrinkage,shrinkage and blowhole,the MAGMA software was used to simulate the temperature and cooling rate changes in the low pressure casting process of the cylinder head,and predict the defect tendency and key development areas of the cylinder head.While reasonably designing the cylinder head die structure and he cooling system of each part of the side die,the numerical simulation results were combined with the ntelligent equipment,and the digital intelligent technology of the low-pressure casting machine was used to control the cooling time sequence and the fine pressure control of the solidification process,so as to avoid the d efects during the solidification and crystallization in the key area of the cylinder head combustion chamber,and improve the internal structure forming density of the aluminum alloy cylinder head castings and the production quality of the low-pressure casting.关键词
