[0045] In this embodiment, a feed hopper 23 is provided on the machine body for feeding materials into the machine body.

[0046] In this embodiment, the discharge end 1a of the machine body is also detachably connected to an extrusion die, which is composed of a coaxial outer die 12, a cooling jacket 11 and an inner die 10, and the outer die 12 is threadedly connected to the discharge end 1a of the extruder to achieve detachability;

[0047] A cooling chamber 110 is provided in the cooling jacket 11, and the cooling chamber can be connected to a water pump through a water pipe. Water is sent into the cooling chamber 110 through the water pump and circulated, so as to cool the inner mold. In other words, a water outlet and a drain are provided on the cooling jacket, and water is supplied to the cooling chamber through the water outlet and discharged from the drain for circulation.

[0048] The inner mold 10 has an inner mold cavity 100 for forming the copper rod. In this embodiment, the diameter of the inner mold cavity 100 is the same as the thickness of the copper rod.

[0049] In the present embodiment, the outer mold and the cooling jacket are fixed by bolts 14, that is, the inner mold in the cooling jacket can be taken out by disassembling the outer mold and the cooling jacket, and the inner mold with different inner mold cavities can be replaced to produce copper rods of different thicknesses. Since the diameters of different inner mold cavities are different from the diameters of the discharge end of the extruder, when the extruder is discharging, the end 100a of the inner mold will be subjected to the thrust of the material extruded by the extruder, which may cause the extrusion mold to become loose over time. Therefore, the present embodiment is provided with a fixed structure, and the fixed structure 3 is provided at the discharge end of the machine body, and the fixed structure 3 can be movably provided on the machine body 21, and a limit end and a limit groove for the limit end to move are provided on the mating surface of the fixed structure 3 and the extrusion mold;

[0050] Wherein, the limiting groove has at least one entrance and one limiting area. When the fixed structure approaches the extrusion die and rotates, the limiting end can enter from the entrance of the limiting groove and move to the limiting area.

[0051] In this embodiment, the limiting grooves (there may be two limiting grooves in this embodiment, and they are distributed on the outer side wall of the outer mold at quasi-circumferential intervals with the outer mold axis as the center) include:

[0052] The main groove body 40 is formed on the outer wall of the outer die 12 of the extrusion die;

[0053] The feed groove 41 (the entrance of the limit groove) is formed on the outer wall of the extrusion die outer die 12, and one end thereof extends and penetrates to the edge position of the extrusion die outer die 12;

[0054] The fixing groove 42 (the limiting area of ​​the limiting groove) is formed on the outer mold 12 of the extrusion mold;

[0055] The feed groove 41, the main groove body 40 and the fixed groove 42 are connected end to end, and the groove walls on both sides of the feed groove 41 and the fixed groove 42 are provided with curved surfaces for guiding the limiting end to enter the main groove body.

[0056] In this embodiment, the fixing structure includes:

[0057] The main ring body 50 is coaxially sleeved on the output end of the body 21;

[0058] The auxiliary ring body 51 is rotatably mounted on the main ring body 50 and is coaxially arranged with the main ring body 50;

[0059] A mounting groove 52 is formed on the inner ring side wall of the auxiliary ring body 51;

[0060] The inner ring body 53 is disposed in the mounting groove 52 and has a limiting end 53a (a protrusion disposed on the inner side wall of the inner ring body 53) that can move in the limiting groove;

[0061] The inner ring body 53 and the auxiliary ring body 51 are coaxially arranged, and a slide post 54 and a slide groove 55 are arranged on the inner ring body 53 and the groove wall of the mounting groove 52, and a limit spring 56 connected to the slide post 54 is arranged in the slide groove 55.

[0062] In this embodiment, the auxiliary ring body 51 and the main ring body 50 are respectively provided with a slide rail 60 and a guide groove 61 adapted to each other, wherein the guide groove 61 is composed of a first groove body 611 formed on the main ring body 50 and arranged coaxially with the main ring body 50, and a second groove body 612 formed on both sides of the first groove body 611;

[0063] The slide rail 60 is composed of a first rail body 601 integrally formed with the auxiliary ring body 51 and adapted to the first slot body 611 , and a second cabinet body 602 adapted to the second slot body 612 .

[0064] In this embodiment, the main ring body 50 is slidably connected to a sliding groove 50b provided on the discharge end 1a of the machine body 21 through a sliding block 50a.

[0065] refer to Figure 1-7 The principle of this embodiment is: when the extrusion die and the discharge end of the extruder are installed, first, the internal thread of the outer die is matched with the external thread of the discharge end of the extruder to realize the installation of the extrusion die. After the installation is completed, the main ring body is driven by the slider to move close to the extrusion die, and the inner ring body of the auxiliary ring body is contacted with the outer die of the extrusion die. When the protrusion enters the feed groove of the limiting groove, the auxiliary ring body is rotated, the protrusion contacts the groove wall of the feed groove, and is guided into the main groove body by the curved groove surface of the feed groove, and the limiting spring is stretched at the same time. When the movable protrusion moves to the fixed groove, the limiting spring drives the inner ring body to reset, and the protrusion enters the fixed groove, thereby ensuring the installation reliability of the extrusion die and the extruder through the cooperation of the inner ring body and the outer die.

[0066] Embodiment 2 is different from Embodiment 1 in that

[0067] like Figure 8-10 As shown, in this embodiment: a radially penetrating sliding cavity 70 is formed on the inner ring body 53, and a limiting column 71 with two ends exposed from the sliding cavity 70 is slidably connected in the sliding cavity 70;

[0068] An airbag body 72 is arranged in the installation groove 52, and an air pipe 73 connected to the airbag body 72 is arranged on the auxiliary ring body. A valve 74 connected to the air pipe 73 is also arranged on the auxiliary ring body 51, and one end of the limiting column 71 is connected to the outer wall of the airbag body.

[0069] In this embodiment, the bottom of the fixing groove 42 is recessed to form a recessed area 42 a for one end of the limiting column 71 to fit.

[0070] In this embodiment, in order to further improve the fixing effect of the extrusion die, when the limiting column is rotated by the secondary ring body and enters the fixing groove from the self-feeding groove, the limiting column is stuck in the recessed area 42a (a blind hole arranged at the bottom of the fixing groove 42), and the air pump is used to inflate the open valve, and the airbag is expanded and the limiting column is pressed, thereby improving the fastening effect of the fixing structure and the extrusion die, and further ensuring the installation reliability of the extrusion die.

[0071] Similarly, when disassembling the extrusion die, first open the valve to release the air (if necessary, use a vacuum pump to extract the gas in the airbag body), so that the limit column can leave the blind hole, then control the limit shaft to move from the fixed groove to the feed groove position by rotating the secondary ring body, and then move the main ring body away from the extrusion die, thereby completing the disassembly and separation of the fixed structure and the extrusion die.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
