Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically a high-precision aluminum profile hot extrusion diversion mold. Background Technology
[0002] A hot extrusion diverter die is a type of die used in hot extrusion processes. Hot extrusion diverter dies are usually equipped with diversion holes to divert the metal billet and then re-merge it, making the metal flow more evenly within the die and helping to improve the quality and dimensional accuracy of the extruded parts.
[0003] The existing hot extrusion shunting dies for aluminum profiles have the following problems when in use: the shunting holes are usually arranged in a ring at the shunting die. Since the forming space of different forming cavities is not the same, the ring-shaped shunting holes are not designed reasonably, which may lead to uneven flow of metal in the die, resulting in problems such as local overheating and stress concentration. At the same time, when the heated billet is put into the hot extrusion shunting die, the pressure seat is usually driven vertically by a hydraulic press, which cannot guarantee the stability of the vertical descent of the pressure seat. Consequently, the billet in the shunting die cannot flow evenly into multiple shunting holes. All of the above affect the quality of the extruded parts. Utility Model Content
