[0002] At present, hot extrusion is mainly used to manufacture long pieces, profiles, pipes, bars and various machine parts of ordinary equal cross-section. Hot extrusion can not only form non-ferrous metals and their alloys with good plasticity and relatively low strength, low and medium carbon steel, but also form high carbon and high alloy steel with high strength.

[0003] Most of the existing hot extrusion mold structures inject the filling material directly into the mold and wait for cooling to obtain the molding material. However, the traditional mold structure is simple, and the filling material input into the mold is very easy to mix with the air and enter the mold. A large amount of air will cause a large number of bubbles in the filling material, so the density of the molding material obtained after cooling is not high, resulting in the quality of the molding material being seriously substandard. Utility Model Content

[0007] Four groups of telescopic rods are fixedly installed on the top of the lower mold, the output ends of the four groups of telescopic rods are connected to the upper mold, and a feed port is provided at the upper end of the upper mold, an upper mold groove corresponding to the lower mold groove is provided at the bottom of the upper mold, an upper cavity is provided in the upper mold, an exhaust hole penetrating the upper cavity is provided in the upper mold groove, and a fan for discharging hot air is installed on one side of the upper mold.

[0008] Preferably, the composite plate is slidably mounted in the side wall of the lower mold groove, and a shock-absorbing pad for buffering is arranged inside the composite plate.

[0009] Preferably, the mounting hole of the fan is connected to the upper cavity.

[0011] Preferably, the guide column is eccentrically welded to the turntable.

[0012] Preferably, the strong spring is located outside the connecting column.

[0013] Compared with the prior art, the utility model has the following advantages:

An upper cavity 10 is opened in the upper mold 8, and an exhaust hole 11 penetrating the upper cavity 10 is opened in the upper mold groove 9. The exhaust hole 11 can only discharge gas, while the filling material cannot pass through. A fan 12 for discharging hot air is installed on one side of the upper mold 8, and the mounting hole of the fan 12 is connected with the upper cavity 10.
