摘要
采用消失模铸造生产柴油机缸盖,由于缸盖结构复杂,消失模模型分4片胶合而成。在工艺设计时,消失模缸盖模具分型要合理,模型珠粒熟化密度要均匀,模型外观品质要达标;在浸涂时,涂料要有良好的涂挂性能,对模簇干重要严格控制;选择合适的烘干工艺。做好这几个环节就能消失模铸造出合格的柴油机缸盖。
Lost foam casting pattern was divided into four slices to glue a whole structure due to its complex structure of cylinder head for diesel engine in lost foam casting.Aiming at processing design,the rational parting surface should be considered for mould of lost foam casting cylinder head with uniform ripening density beads as well as qualified pattern appearance.In addition,coating should have the satisfied smearing behavior,especially strictly controlling the dry weight of pattern cluster.Proper baking parameters should be paid attention.Based on above measures,the qualified lost foam casting cylinder head could be produced successfully.
