Mould Design and Casting Process Improvement on Vibrator Shell
Vibrator shell is a part with complex structure. While the vibrator shell is designed and manufactured by traditional sand casting process, more than 80％ castings are found the defects of porosity, shrinkage and pouring-shortage at the top. Aiming to the problems in traditional sand casting, this paper focused on the improvement of castings structure and the optimization of casting process. Designing process bar in the gate-channel region which is connected with the gate in castings is used to improve the castings structure, and low speed filling and solidification under high pressure are adopted to optimize the casting process which is finished by self-made four-column type hydraulic machine equipped. It can be seen that the castings quality can be greatly improved by process improvement.
