There are also some steel discharging machines that adopt hollow ejector rods and cool them by introducing cooling water into the interior of the hollow ejector rods. Although it can avoid the overheating of the ejector rods, due to the significant reduction in the strength and stiffness of the hollow ejector rods themselves, they are also prone to deformation during use.

The number of the solid rods 10 and the buffer components 11 are both set to two. The two solid rods 10 respectively penetrate through the corresponding cold conduction plates 8 and are connected with the corresponding buffer components 11.

[0025] With this solution, under the action of the heat conduction plate 8, the cold quantity brought by the cooling water can be transferred to the hollow rod 4, the solid rod 10 and the top block 9, so as to play a role in cooling them; through the buffer assembly 11 provided, when the top block 9 contacts the billet, it can play a role in buffering and energy dissipation; through the mutual cooperation of the above structures, the service life of the present utility model can be improved.
