Development of a high-performance equipment for removing residual liquid on the surface of precision casting resin molds
On the basis of the current stereo lithography apparatus(SLA)post-processing process,an innovative resin mold cleaning method that is efficient,fast,and safe after printing and forming is proposed.This method not only meets the requirements of low surface resin residue and small size deformation in precision casting technology,but also improves the safety of the cleaning process and reduces the difficulty of operation for users and an spray sealed cleaning equipment has been developed to replace traditional soaking open cleaning cylinders,using repeated spraying and blowing methods to quickly remove residual resin on the surface and prevent alcohol cleaning agents from entering the internal cavity and causing deformation.Alcohol is supplied in pneumatic quantities to increase the usage rate of alcohol cleaning agents and reduce the risk of large-scale storage.By adopting multi-sensor monitoring,PLC control,and human machine interface(HMI)visualization operation,various functions such as process safety automatic monitoring and waste liquid automatic recovery are achieved.Finally,the feasibility of the new cleaning method and the practicality of the cleaning equipment were verified through testing.
