Furthermore, semicircular limiting plates are integrally formed at two ends of the upper die cover and the lower die cover, and valves are arranged on the limiting plates at two ends of the lower die cover. The purpose is that through this kind of setting for the unnecessary moisture that the mould of pouring separated out because of centrifugal force can discharge the mould of pouring through the valve on the limiting plate in the rotation process.
Furthermore, the edge of the upper die cover and the edge of the lower die cover are all surrounded by flanges, the rectangular openings are evenly arranged on the flanges of the upper die cover at intervals, and the connecting plates are evenly arranged on the flanges of the lower die cover at intervals. Its purpose is convenient for go up the mould lid through this kind of setting and is connected with the mutual lock of lower mould lid.
Furthermore, the inner walls of the upper die cover and the lower die cover are fixedly connected with smooth metal layers. Its purpose is, be convenient for drawing of patterns shaping and subsequent clearance through this kind of setting.
Further, it is a plurality of one side fixedly connected with curved closing plate of arc planking and last mould lid contact, and the size and the shape of closing plate are the same with the big or small shape of pan feeding opening, the both ends of arc planking rotate respectively and are connected with the connection clamp plate, and one section that the connection clamp plate kept away from the arc planking can be dismantled with the flange of last mould lid through the screw and be connected. Its purpose is through this kind of setting for the fashioned concrete pipe can form the smooth complete tubulose in surface, conveniently opens or closes the opening and the sealing that the closing plate realized the pan feeding opening simultaneously.
