侧向挤压陶瓷型芯模具设计与型芯质量评估

Quality evaluation of the ceramic core shaped by side extrusion and mould design

断面积较小的型芯在浇铸的时候要经受一定的冲击力,需要有较高的强度,否则会发生严重的断芯现象。为了和目前现有的浇注成形方法的比较,本文利用侧向挤压的方法进行陶瓷型芯的挤压实验,设计了一套侧向挤压模具装置,挤出的产品具有较好的强度,解决了断芯的问题,也证明了该方法的可行性与高效性。

The small-size core used in investment casting must have some strength ,if not ,the casting will be inferior. In this paper a side extrusion experiment, the relevant mold and material will be designed. The result show that the core by this method has fine performance and that this way is feasible and has high efficiency.
