The manipulator is a kind of fully automatic modeling auxiliary equipment. Because of its high degree of automation, precise action and reliable performance, it improves the stability and practicability of the entire modeling line. It is mainly used for mold-drawing and box-turning and box-closing of molds in the final stage of modeling. It is suitable for automated production lines and production lines with high modeling accuracy. The parameters of the manipulator are determined non-standard according to the user''''''''s productivity and the size of the flask to achieve customized production.
