Variable cross-section extrusion mold and variable cross-section extrusion molding method (variable cross section extruding die and variable cross section extrusion molding metal

摘要

The die (24) and the die (24) which can be moved to the direction directly exchanged with the extrusion direction of the shaping material, and the area of the extrusion shaping hole (31) extruded by the shaping material is changed,In the extrusion forming chamber, the extrusion direction is,Can reverse the setting, but also in the outsourcing department to record the war,From one side of the remote platform to the other side, the drill (27) formed by taper (27b) with gradually smaller overall dimension is provided, and the die for variable single side extrusion is used,The die is moved to change the extrusion forming hole (31), and the cone of the upper drill bit (27) in the extrusion forming hole is changed,By reversing, the shape and internal dimensions of the imaginary plastic products are extruded.
