Vacuum extruder

The utility model relates to a vacuum extruder which is a mechanism device used for brick and tile manufacture. The purpose is to provide a vacuum extruder which suits various materials and processes and can also produce multiple products and can be detached and combined. A receiving material box and a vacuum chamber are connected for an integration by a clay barrel which is communicated from left to right, and the receiving material box, a vacuum box, the clay barrel, a frame head, and a mould all are jointed by bolts; a screw reamer set is piecewise sheathed on a transmission shaft, and the middle part of the vacuum box is provided with a vacuum box beating clay plate which is connected with the beating clay plate of the receiving material box through a universal coupling; a main shaft drives the beating clay plate to rotate through gearwheels and drives the reamer head and the screw reamer set to rotate through the coupling, making the materials pass through the frame head and be shaped by the mould.
