AI Technical Summary
Technical Problem
In existing lost foam casting equipment, the sand storage tank is prone to clogging and the sand box is prone to displacement when vibrating, resulting in problems such as poor material feeding and unstable fixation.
Method used
A mixing assembly and a fixing assembly are installed in the sand storage tank. The molding sand is mixed by a motor-driven helical gear that drives the rotating shaft and the mixing rod to prevent clogging. The sand box is fixed by a positioning plate and fixing bolts to prevent displacement.
Benefits of technology
It effectively prevents molding sand from clogging, ensures smooth material feeding, stabilizes the sand box position, and improves work efficiency and safety.
