The utility model relates to a split type plug's use belongs to extrusion frock field. The plug divide into core rod head (1), plug tail (2) two parts, and threaded connection is passed through in core rod head (1) and plug tail (2). The utility model discloses be divided into upper and lower two parts with former plug, make respectively, improve tip mechanical properties down alone, prevent the phenomenon that broke the emergence bottom in extrusion process. Adopt the saw -tooth thread to couple together upper and lower two parts, can carry out quick online the change under the abominable operating mode that the plug used. The plug that broke the bottom can obtain restoreing to a plurality of upper ends can be joined in marriage to a plug lower extreme, save plug restoration, production cost, improve production efficiency. 本实用新型涉及种分体式芯棒的使用，属于挤压工装领域。本实用新型所述芯棒分为芯棒头(1)、芯棒尾(2)两部分，芯棒头(1)和芯棒尾(2)通过螺纹连接。本实用新型将原芯棒分为上、下两部分，进行分别制作，单独提高下端部分机械性能，防止在挤压过程中发生底部拉断的现象。采用锯齿形螺纹将上、下两部分连接起来，在芯棒使用的恶劣工况下能够进行快速在线更换。底部拉断的芯棒可以得到修复，并且个
