[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0039] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A copper flat wire extrusion die includes a square steel frame base 1, a quick docking and fixing mechanism 2, and an assembly forming module 3; the square steel frame base 1 has an installation groove 11 in the middle.

[0040] The mounting slot 11 is equipped with a quick docking and fixing mechanism 2 for quickly positioning and fixing the assembled molding module 3;

[0041] The quick docking and fixing mechanism 2 includes a fixing component and a movable component; the movable component is installed on the left and lower sides of the mounting slot 11; the fixing component is installed on the right and upper sides of the mounting slot 11.

[0042] like Figure 3 As shown, the modular molding module 3 includes a first molding block 31, a second molding block 32, a third molding block 33, a U-shaped fixing frame 38, splicing components, and limiting components; splicing components are installed on the U-shaped fixing frame 38, the first molding block 31, the second molding block 32, and the third molding block 33; the first molding block 31, the second molding block 32, and the third molding block 33 are installed sequentially from left to right within the U-shaped fixing frame 38.

[0043] The limiting components are symmetrically installed on the upper left and right sides of the U-shaped fixing frame 38;

[0044] In this invention, under normal working conditions of the mold, the first molding block 31, the second molding block 32, and the third molding block 33 are inserted into the U-shaped fixing frame 38 through the splicing assembly, and are fixed to the U-shaped fixing frame 38 by the limiting assembly; this prevents the first molding block 31, the second molding block 32, and the third molding block 33 from moving during use and affecting the molding quality;

[0045] Then, the U-shaped fixing frame 38 is placed into the mounting slot 11. The movable component is then moved toward the fixed component. During the movement, it will touch the U-shaped fixing frame 38 and move it together until the upper and right ends of the U-shaped fixing frame 38 are pressed against the fixed component, and the lower and left ends of the U-shaped fixing frame 38 are pressed against the movable component. This completes the fixing of the U-shaped fixing frame 38 to the square steel frame base 1.

[0046] Then, the square steel frame base 1 is installed as a whole into the mold slot opened on the shoe seat of the extruder;

[0047] If the first molding insert 31 is worn, rotate the left limiting component to release the fixation of the first molding insert 31, and then pull out the worn first molding insert 31. There is no need to completely disassemble the entire molding assembly, which reduces standby time and reduces the extra labor of the operator. Similarly, when the third molding insert 33 is worn, rotate the right limiting component to release the fixation of the third molding insert 33. If the second molding insert 32 is worn, rotate the left and right limiting components to release the fixation of the second molding insert 32.

[0048] By combining the movable and fixed components, the device can more quickly and accurately position and clamp the U-shaped fixed frame 38. The operation is simple, reducing the maintenance difficulty for operators and further improving the practicality of the device.

[0049] like Figure 2 As shown, the fixing component includes a fixing rectangular block 23; one fixing rectangular block 23 is fixedly installed on the inner top of the mounting groove 11; the other fixing rectangular block 23 is fixedly installed on the right inner wall of the mounting groove 11.

[0050] like Figure 2 and Figure 5 As shown, the movable component includes a fixed wedge block 22, a drive screw 24, a knob 25, a movable wedge block 26, and a sliding block 28; one fixed wedge block 22 is fixedly installed on the left inner wall of the mounting groove 11; the other fixed wedge block 22 is fixedly installed on the inner bottom of the mounting groove 11.

[0051] The movable wedge block 26 and the fixed wedge block 22 are in a sliding connection.

[0052] A sliding groove 27 is provided on the outer side of the movable wedge block 26;

[0053] Sliding block 28 and sliding groove 27 are in a limited sliding connection;

[0054] The outer end of a drive screw 24 is threaded to the upper left side of the square steel frame base 1; the inner end of the drive screw 24 is rotatably connected to the sliding block 28 in the upper movable wedge block 26.

[0055] The outer end of another drive screw 24 is threaded to the lower left side of the square steel frame base 1, and the inner end of the drive screw 24 is rotatably connected to the sliding block 28 in the lower movable wedge block 26.

[0056] The knob 25 is fixedly connected to the outer side of the drive screw 24;

[0057] like Figure 4 As shown, the splicing assembly includes a limiting insert 35; slots 34 are symmetrically provided on the left and right sides of the U-shaped fixing frame 38; slots 34 are provided at the ends of the first molding insert 31 and the third molding insert 33 that are close to each other; and a limiting insert 35 is fixedly installed at the ends of the first molding insert 31 and the third molding insert 33 that are far apart from each other, and the limiting insert 35 is inserted into the slots 34 provided on the U-shaped fixing frame 38.

[0058] Furthermore, the left and right ends and the upper and lower sides of the second molding block 32 are symmetrically fixed with limiting blocks 35 that are inserted into the slots 34 opened on the first molding block 31 and the third molding block 33.

[0059] like Figure 4 As shown, the limiting component includes a baffle 36 and a torsion spring 37; the baffle 36 is rotatably mounted on the upper end of the U-shaped fixing frame 38; the torsion spring 37 is wound around the rotation axis of the baffle 36 and the U-shaped fixing frame 38; one end of the torsion spring 37 is fixedly connected to the baffle 36; and one end of the torsion spring 37 is fixedly connected to the U-shaped fixing frame 38.

[0060] The torsion spring 37 ensures that the baffle 36 always tends to rotate inward.

[0061] Both the movable wedge block 26 and the fixed rectangular block 23 are fixedly equipped with anti-slip pads at one end near the U-shaped fixing frame 38.

[0062] In this utility model, when the mold is in use, the baffles 36 on the left and right sides are flipped outwards at the same time; during the rotation process, the baffles 36 compress the torsion springs 37.

[0063] The limiting plug 35 installed on the left side of the first molded plug 31 is aligned with the slot 34 opened on the left side of the U-shaped fixing frame 38 and inserted. Then, the limiting plug 35 installed on the left side of the second molded plug 32 is aligned with the slot 34 opened on the right side of the first molded plug 31 and inserted. Finally, the limiting plug 35 installed on the right side of the third molded plug 33 is aligned with the slot 34 opened on the right side of the U-shaped fixing frame 38 and inserted. The limiting plug 35 installed on the right side of the second molded plug 32 will also be inserted into the slot 34 opened on the left side of the third molded plug 33.

[0064] Then the baffle 36 is released, and the torsion spring 37 returns to its original position, causing the baffle 36 to reset. At this time, the left torsion spring 37 is in contact with the upper end of the first molding block 31 and the upper left side of the second molding block 32; the right torsion spring 37 is in contact with the upper end of the third molding block 33 and the upper right side of the second molding block 32.

[0065] If the first molding insert 31, the second molding insert 32, or the third molding insert 33 is worn, rotate the torsion spring 37 on the corresponding side, and then pull the worn first molding insert 31, the second molding insert 32, or the third molding insert 33 upwards.

[0066] Then, the U-shaped fixing frame 38 is placed into the mounting slot 11, and the two knobs 25 are rotated at the same time. The rotation of the knobs 25 drives the drive screw 24 to rotate, so that the drive screw 24 moves into the mounting slot 11.

[0067] During the movement of the drive screw 24, it also pushes the sliding block 28 to move the movable wedge block 26. At this time, the movable wedge block 26 on the left slides down along the fixed wedge block 22 on the left; the movable wedge block 26 on the lower side slides to the right along the fixed wedge block 22 on the lower side. During the movement, the right end of the movable wedge block 26 on the left side will drive the U-shaped fixed frame 38 to move to the right, and the upper end of the movable wedge block 26 on the lower side will drive the U-shaped fixed frame 38 to move upward. Until the upper end of the U-shaped fixed frame 38 is pressed against the upper fixed rectangular block 23, the right end of the U-shaped fixed frame 38 is pressed against the right fixed rectangular block 23, and the lower end of the U-shaped fixed frame 38 is pressed against the lower movable wedge block 26, and the left end of the U-shaped fixed frame 38 is pressed against the left movable wedge block 26, the fixing of the U-shaped fixed frame 38 and the square steel frame base 1 is completed.

[0068] Furthermore, during the movement of the movable wedge block 26, the sliding block 28 will also move along the sliding groove 27 in a direction away from the U-shaped fixed frame 38, so that the drive screw 24 maintains the pushing force on the sliding block 28.

[0069] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
