[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-2 A wire drawing die for a wire drawing machine comprises: a fixed plate 1, a first wire entry hole 12 is horizontally penetrated on the fixed plate 1, and a guide cavity 11 is horizontally opened and perpendicular to the first wire entry hole 12, and a slide groove 13 is opened below the guide cavity 11; a die mounting part 2 is guided and installed in the guide cavity 11, and a plurality of wire drawing eye dies 21 of different models are installed horizontally and spaced on the die mounting part 2, and a positioning hole 22 is opened on the top; a driving mechanism 3 is installed in the slide groove, driving the die mounting part 2 to move along the guide cavity 11 and then adjusting the wire drawing eye dies 21 of the corresponding model to the first wire entry hole 12. A positioning mechanism 4 is installed on the fixed plate 1 and has a positioning plug-in 41. After the die mounting part 2 determines the position, the positioning plug-in 41 is embedded in the positioning hole 22. It can be understood that the die mounting part 2 can be installed in the guide cavity 11 and can move left and right, and the required wire drawing eye dies 21 can be adjusted to the position of the first wire entry hole 12 by moving left and right. The driving mechanism 3 can be driven by a cylinder, an electric push rod, a screw 31, etc. For example, a sleeve 23 located in the slide groove 13 is installed on the mold mounting part 2, and the driving mechanism 3 includes a screw 31 threadedly matched with the sleeve 23 and a motor 32 that drives the screw 31 to rotate. In this way, the motor 32 drives the screw 31 to rotate forward and backward, so that the sleeve 23 drives the mold mounting part 2 to move left and right. The cooperation between the positioning plug-in 41 and the positioning hole 22 plays a positioning role in the mold mounting part 2, and the positioning plug-in 41 can be manual or automatic. With such a setting, when it is necessary to replace another type of wire drawing eye die 21, the driving mechanism 3 can drive the mold mounting part 2 to move in the guide cavity 11, and then move the corresponding type of wire drawing eye die 21 to the first wire entry hole 12, and then the positioning plug-in 41 on the positioning mechanism 4 is embedded in the positioning hole 22, and the position of the mold mounting part 2 is locked to achieve automatic mold change.

[0026] refer to Figure 4-5In some embodiments, the mold mounting member 2 is horizontally spaced apart with mounting grooves 26 corresponding to each type of wire drawing eye die 21, one side of the mounting groove 26 is an opening, and the mold mounting member 2 is also equipped with a cover plate 24 for holding the wire drawing eye die 21 at the opening; the mold mounting member 2 and the cover plate 24 are provided with second wire inlet holes 25 connected to and corresponding to a plurality of mounting grooves 26. It can be understood that the end of the mounting groove 26 away from the opening does not penetrate the mold mounting member 2, and the wire drawing eye die 21 can be embedded in the mounting groove 26 for installation. The cover plate 24 can be installed on the mold mounting member 2 by means of bolts, buckles, etc., and pressed against the wire drawing die to fix it in the mounting groove 26. The aperture of the second wire inlet hole 25 is smaller than the outer diameter of the wire drawing eye die 21. Further, the second wire inlet hole 25 is coaxially arranged with the mounting groove 26. With such arrangement, after the wire drawing eye die 21 has been worn out by friction for a long time, the wire drawing eye die 21 can be replaced by opening the cover body, thereby ensuring the overall service life.

[0027] refer to Figure 2-3 In some embodiments, the top of the mold mounting member 2 is vertically provided with a guide hole 14 extending to the guide cavity 11, and the positioning plug-in 41 is guided and installed in the guide hole 14; the positioning mechanism 4 also includes: an abutment member 42 installed at the top of the guide hole 14, and a guide rod 43 is installed on the top of the positioning plug-in 41 to guide the abutment member 42, and the guide rod 43 is sleeved with a spring 44 with two ends respectively abutting against the abutment member 42 and the top of the positioning plug-in 41, and a telescoping device 45 that drives the guide rod 43 to move vertically. It can be understood that the abutment member 42 can adopt a hollow shell structure, the spring 44 is in a compressed state, and the positioning plug-in 41 adopts a rod-shaped structure, and the output end of the telescoping device 45 faces upward to drive the guide rod 43 to move upward, which can adopt a cylinder, an electric push rod, etc. In this way. Since the compressed spring 44 will press the positioning plug-in 41 downward, the connector is actively inserted into the positioning hole 22. When the mold mounting part 2 needs to be moved, the telescopic device 45 moves the guide rod 43 upwards and drives the positioning plug-in 41 upwards to disengage from the positioning hole 22. Of course, the guide rod 43 can also be manually pulled up. Furthermore, a plurality of the positioning holes 22 correspond to each wire drawing eye die 21 one by one, and are located directly above the center of each wire drawing eye die 21; the positioning plug-in 41 is located directly above the center of the first wire entry hole 12. In this way, when the center of the wire drawing eye die 21 is inconsistent with the center of the first wire entry hole 12, the positioning plug-in 41 cannot be inserted into the positioning hole 22, which can play a role in detecting the position of the wire drawing eye die 21.

[0028] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
