[0002] In modern industry, large lifting shafts are core load-bearing components of heavy machinery such as cranes and port loading and unloading equipment. Their quality and performance directly affect the safety and reliability of the equipment. As industrial equipment develops towards larger size and heavier load, higher requirements are placed on the size, precision and mechanical properties of large lifting shafts. Although machining can improve manufacturing precision, it consumes more materials. Forging can improve the strength of components. Using molds to form large lifting shafts can better manufacture shaft components with more complex structures.

[0003] However, existing molds are mostly used for extrusion forging of single-sized parts. The internal structure of the molds is often only suitable for shaft parts of specific sizes and shapes. In particular, shaft parts often need to be customized with different diameters or lengths according to requirements. During manufacturing, manufacturers have to frequently change special molds, which not only makes the mold assembly and disassembly process cumbersome and greatly reduces production efficiency, but also causes a serious waste of resources such as raw materials and storage space due to a large number of idle special molds. Therefore, this utility model is proposed. Utility Model Content

[0026] Please see Figures 1-7 As shown, a multi-directional displacement composite mold structure for forging large hanging shafts includes a main mold 1 that interlocks with each other. Both ends of the main mold 1 are provided with auxiliary molds 2. The main mold 1 and auxiliary molds 2 are integrated. In actual use, multiple molds are required to form a composite mold with different diameters, shaft lengths and shapes. It also includes a mold closing mechanism 3 that drives the main mold 1 to press together. Semicircular plates 101 are fixed on both sides of the main mold 1. A plug-in post 102 is fixed on one side of the semicircular plate 101. The side wall of the auxiliary mold 2 is provided with a corresponding receiving notch and plug-in groove. An external protrusion 201 is fixed on the side wall of the auxiliary mold 2. The top and bottom of the main mold 1 are installed with a snap-fit ​​structure 4 by fixing bolts. A translation frame 5 is provided around the snap-fit ​​structure 4.

[0027] like Figure 5 As shown, the snap-fit ​​structure 4 includes a snap-fit ​​body 401. A snap-fit ​​notch is provided on one side of the snap-fit ​​body 401 corresponding to the outer protrusion 201. An installation housing 402 is fixed on one side of the snap-fit ​​body 401. A fixing hole is provided on the installation housing 402 for the mating fixing bolt to pass through. A threaded hole is provided on the main mold 1 for the mating fixing bolt to install, so that the relative positions of the main mold 1 and the auxiliary mold 2 can be fixed.

[0028] like Figure 4 and Figure 5 As shown, the snap-fit ​​body 401 has a sliding groove 403. The translation frame 5 includes a parallel column 501 located on one side of the snap-fit ​​structure 4. A sliding protrusion 502 is fixed on the parallel column 501 corresponding to the sliding groove 403, which facilitates the movement of the main mold 1 and the auxiliary mold 2. A connecting vertical plate 503 is fixed between the parallel columns 501. A positioning mechanism 6 for limiting the auxiliary mold 2 is installed on the connecting vertical plate 503, which can fix the relative position of the upper and lower parallel columns 501.

[0029] like Figure 6As shown, the positioning mechanism 6 includes a positioning frame 601. One end of the positioning frame 601 is mounted on the connecting vertical plate 503 by fastening bolts, and the other end of the positioning frame 601 extends to one side of the sub-mold 2. A corresponding track bar 602 is fixed on the side wall of the sub-mold 2.

One end of the limit post 303 passes through the parallel post 501, which can better restrict the movement of the limit post 303 and make the movement of the limit post 303 smoother.

[0031] In use, multiple composite molds can work together to form a complete mold for the lifting shaft. During operation, the hydraulic telescopic rod 302 pushes the main mold 1 and the auxiliary mold 2 to close. When disassembly is required, the positioning frame 601 is removed first, and then the auxiliary mold 2 is disassembled. The main mold 1 can be directly slidably engaged with the parallel column 501, making movement easier and also helping to limit the position of the main mold 1. Replacing the auxiliary mold 2 with different lengths can adjust the size and specifications of the lifting shaft, avoiding complete mold disassembly.
