摘　　要：为了强化最新科研成果和先进制造技术在人才培养上的应用及示范,提高学生对工程前沿技术的兴趣,以轮胎花纹活络模为例,将3D打印技术与砂型铸造相结合,快速制造出铸型,并基于逆向工程对铸型进行三维扫描反求对比,实现对铸型的精度检测,铸型平均尺寸精度达到±0.5mm。试验最终获得铸件平均尺寸精度达到±0.6mm,满足砂型铸造国家标准要求。该实训教学体系瞄准科技前沿技术,开阔了学生眼界,激发学生对专业前沿技术的兴趣。In order to strengthen the application and demonstration of the latest scientific research achievements and advanced manufacturing technology in talent training, and to improve students' interest in engineering frontier technology, the tire pattern active mold has been taken as an example to combine 3D printing technology with sand casting to quickly manufacture the mold. On the basis of reverse engineering to compare the three-dimensional scanning of the mold to achieve the accuracy of the mold. The average dimensional accuracy of the mold is ±0.5mm. The final average dimensional accuracy of the casting obtained by test achieves ±0.6mm, which meets the requirements of the national standard for sand casting. The practical teaching system is aimed at cutting-edge technology, broadening the horizons of students and stimulating students' interest in professional cutting-edge technology.
