选择性激光烧结法快速制造柴油机气缸盖全套砂芯

摘要

概述了快速成形技术的工作流程.详细介绍了采用选择性激光烧结法快速成形设备成功制作K10气缸盖完整的全套砂芯的过程,缩短了新产品的试制周期.生产的K10气缸盖内腔光洁、无烧结、无缩孔、缩松等铸造缺陷,各处壁厚均匀,完全满足产品的技术要求.%The workflow of rapid prototyping technology was reviewed. The process of making K10 cylinder head complete set of sand core by selective laser sintering rapid prototyping equipment was presented, by which the development period of new product was shorten. The cylinder heads were produced successfully with uniform wall thickness, cleaned cavity, and without sintering, shrinkage or dispersed shrinkage defects, which meet the technological requirements.
