In production, 1000T extruders are mainly used to extrude aluminum bars to form profiles of various shapes required for industrial manufacturing and life. The extrusion rod contained in the extruder is a key extrusion component.

[0003] In the prior art, an aluminum rod is placed in an extrusion cylinder with a die hole, heated and softened, and then an extrusion rod is pushed by a high-power hydraulic cylinder. An extrusion pad is provided at the front end of the extrusion rod. The heated and softened aluminum rod is extruded from the precision forming hole of the die under the strong pressure of the extrusion pad, thereby obtaining an aluminum alloy profile product with the same size and shape as the die hole. However, the extrusion rod does not have a hollow structure and a cooling structure for strengthening support, so it is inconvenient to ensure the structural stability and bearing capacity of the extrusion rod. At the same time, it is not possible to transmit force faster, reduce the friction and resistance of the material during the extrusion process, and the coolant circulation cannot help control the temperature during the extrusion process to reduce thermal deformation, thereby affecting product quality and production efficiency.

[0009] As a preferred solution of the utility model, the specific structure of the reinforcing positioning plate is a hexagonal plate body, and a plurality of the reinforcing positioning plates are evenly spaced and distributed along the length direction inside the hollow structure.

[0010] As a preferred solution of the utility model, a plurality of reinforcing ribs are arranged in a circular shape with equal intervals, and two ends of the plurality of reinforcing ribs are respectively connected to two ends of the inner wall of the hollow structure.

[0011] As a preferred solution of the utility model, two ends of the U-shaped cooling channel respectively penetrate and connect the interior of the coolant inlet and the coolant outlet.
