[0016] The utility model provides a kind of mold sleeve of replacement machine platform pressurizes, solve the problem that extrusion mold is not matched in extrusion tonnage, cannot produce, by using the mold sleeve of new structure design realizes extruding large tonnage mold with small tonnage machine platform, to balance order, save cost.

[0017] Please refer to Figure 1 、 Figure 2The utility model provides a kind of die sleeve of replacement machine platform pressure material, it is shell cover shape, die sleeve 1 with die cavity 2 and inlet guide port 3 there is, die cavity 2 and inlet guide port 3 are communicated and in from inlet to discharge direction through die sleeve 1.Die cavity 2 is used to accommodate, install fixed die, inlet guide port 3 is located in the inlet side of die.Inlet guide port 3 is gradually enlarged horn mouth shape from inlet to discharge direction, and, the diameter of inlet guide port 3 inlet side is consistent with the diameter of raw material bar that extruding platform is applicable, the diameter of inlet guide port 3 discharge side is less than die diameter, and with the diameter of raw material bar that die needs is consistent.

[0018] In the scheme, the used die is extrusion die with relatively large extrusion tonnage, and the diameter size is also relatively large; the used extruding machine platform is machine platform with smaller extrusion tonnage, and the diameter size of extrusion cylinder outlet and the used raw material aluminum bar is also smaller.If die sleeve of the scheme is not used, and die is directly installed, profiled material will not be normally formed due to less feeding of small machine platform.After installation of die with die sleeve of the scheme, extrusion cylinder discharge side is connected with inlet guide port 3 inlet side of die sleeve 1, and raw material aluminum bar can be matched into inlet guide port 3, and then the radius of die inlet side is enlarged through horn mouth structure, which is equivalent to enlarging bar diameter, so as to be matched with the size of die inlet side, so that extrusion production can be carried out.

[0019] More specifically, the inner side of die cavity 2 is formed with positioning step 4 at inlet side, the positioning step 4 is formed between different diameter parts in die cavity 2, and the side towards discharge side is plane (annular), inclined surface (conical) or curved surface, the positioning step 4 is matched with the shape of die outer side at inlet side, so that die can be better installed and positioned, and matched with die to ensure that die is fixed during extrusion.

[0020] The inner side of die cavity 2 is formed with positioning groove 5 at discharge side, for example, four positioning grooves are uniformly distributed in circumference, and the outer side of die also has groove, and die is positioned after positioning groove 5 is aligned with the groove of die outer side. The inner side of die cavity 2 is open at discharge side and has installation chamfer 6, so that die is more convenient to install. Die sleeve 1 has screw mounting hole 7 at the side position of die cavity 2, and die sleeve can be positioned as a whole by screw.
