Description

Technical Field

[0001] The utility model relates to the technical field of metal extruders, in particular to a four-direction locking mechanism for a die seat of a metal extruder. Background Art

[0002] Metal extrusion processing is an important method of pressure processing using the principle of metal plastic forming. Metal ingots are processed into tubes, rods, T-shaped, L-shaped and other profiles at one time through extrusion. Metal extruder is the most important equipment for metal extrusion processing. At present, in the process of processing metal ingots, a matching mold seat is needed to shape the metal ingot. In order to prevent the mold seat from sliding, a locking mechanism is needed to position the mold seat.

[0003] Although the current locking mechanism can lock and position the mold seat, it still has some shortcomings when used. For example, it is difficult to lock the mold seat in four directions synchronously during use, which causes the mold seat to slide easily during use, resulting in unqualified metal ingot forming parts. Therefore, a four-direction locking mechanism for the mold seat of a metal extruder is proposed. Utility Model Content
