汽车垫块铸造工艺设计与优化

Design and Optimization of Casting Process for Automobile Cushion Block

以某汽车垫块为研究对象,根据铸件的结构特点,设计了底注搭边式浇注系统的砂型铸造工艺。对铸件上无法直接成形部分,采用分块设计的砂芯成形,且砂芯之间设置了定位和芯头,有效避免了铸型错位。运用AnyCasting软件对铸件进行数值模拟分析,针对铸件出现的缺陷,设计了冒口和冷铁对其进行补缩,使铸件实现了顺序凝固。最终生产出的铸件精度较高,质量得以保证,满足工作要求。

According to the structural characteristics of the automobile cushion block,the sand casting process of the bottom pouring and lap gating system was designed.For the portions that cannot be directly formed on the casting,the sand core with block design is used for forming,and the positioning and core head are set between the sand cores,effectively avoiding the mold dislocation.By using AnyCasting software numerical simulation analysis is carried out on the casting.Aiming at the defects of the casting,the riser and chills are designed,effectively controlling the sequential solidification of the casting.The precision of the final casting is high,the quality can be guaranteed and meet the work requirements.
