More Information
Summary:Disclosed is a molding machine for simultaneously making upper and lower molds with cope and drag flasks, a matchplate, upper and lower squeezing boards, and a lower filling frame. This machine also includes a cylinder for raising and lowering the lower squeezing board, a driving mechanism that includes pneumatic and hydraulic piping systems for driving the cylinder using an air-on-oil system, and a controller for controlling the driving mechanism. The drag flask, the matchplate, the filling frame, and the lower board define a lower molding space, while the matchplate, the upper board, and the cope flask define an upper molding space such that the controller controls the driving mechanism to drive the cylinder at a low pressure. The lower squeezing board is raised to squeeze the molding sand for simultaneously making the two molds such that the controller controls the driving mechanism to drive the cylinder at a high pressure.
