Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and more specifically, to a spliced ​​metal casting for cast iron. Background Technology

[0002] In the industrial manufacturing sector, metal castings are widely used in key areas such as aerospace, rail transportation, energy equipment, and engineering machinery due to their excellent mechanical properties, forming stability, and material adaptability. With the increasing demands of modern industry for larger, more customized, and lighter equipment, the limitations of traditional integral metal castings are becoming increasingly apparent, driving the development and exploration of interlocking metal casting technology.

[0003] Traditional monolithic metal castings face multiple challenges in the manufacturing process. For large or extra-large castings, forming requires extra-large molds and melting equipment, which not only leads to high equipment investment costs and long production cycles, but also makes them prone to problems such as uneven flow of molten metal in the mold and differences in cooling rates. Hollow castings, in particular, are prone to internal defects such as shrinkage cavities, cracks, and porosity, significantly reducing the yield of castings. For partially assembled metal castings, especially those with hollow centers, the presence of assembly gaps not only affects the sealing performance and dimensional accuracy of the components, but may also cause corrosion due to water and dust accumulation in the gaps, shortening the service life of the castings.

An inclined block 19 is fixedly connected to the side of the upper and lower movable plates 14 facing each other. The outer surface of the inclined block 19 is provided with an inclined surface corresponding to the conical cover 111.

[0015] Specifically, by utilizing the groove inside the conical cover 111 and the inclined surface of the inclined block 19 on the side of the movable plate 14 at both ends, when the fixed bolt 110 is rotated to move the conical cover 111 toward the movable plate 14, the inclined block 19 at both ends is moved toward each other by the limiting of the conical cover 111, thereby compressing the movable spring 18, and the positioning rod 15 at both ends pulls the pressing block 16 to move toward each other, so that the bottom cover 2 and the top cover 3 at both ends are fixed to the intermediate frame 1. The assembly is simple and convenient, and it is easy to disassemble and assemble the metal casting.

[0016] like Figure 3 and Figure 5 As shown, the top cover 3 includes a fixed cover 31, and locking blocks 32 are fixedly connected to the four sides of the fixed cover 31. Fixing holes 33 are opened on both sides inside the locking blocks 32, and a sealing groove is opened at the bottom of the fixed cover 31.

[0017] The fixing holes 33 on the four sides of the bottom cover 2 and the top cover 3 are respectively engaged with the outer surfaces of the positioning rods 15 on the four sides of the support frame 11. Through the action of the fixing bolts 110, the conical cover 111 is sleeved on the outer surfaces of the inclined blocks 19 at both ends, so that the movable plates 14 at both ends drive the positioning rods 15 at both ends to move towards each other, thereby fixing the intermediate frame 1, the bottom cover 2 and the top cover 3. And through the connection between the sealing ring 12 and the sealing groove of the bottom cover 2 and the top cover 3, the sealing performance of the metal casting is improved.

[0018] The bottom cover 2 has the same structure as the top cover 3. Both the bottom cover 2 and the top cover 3 have multiple mounting brackets 38 fixedly connected to their inner walls. The bottom of the mounting bracket 38 has a positioning groove 39. The top of the fixed cover 31 is threaded with a connecting bolt 36. The bottom of the connecting bolt 36 is rotatably mounted with a connecting block 37. Both sides of the connecting block 37 are provided with snap-fit ​​blocks 310. Both sides inside the connecting block 37 are provided with snap-fit ​​springs. The snap-fit ​​blocks 310 are movably sleeved inside the connecting block 37 and connected to the snap-fit ​​springs.

[0019] The top cover 3 also includes a component 311. The top of the component 311 is fixedly connected to a positioning strip 312. The positioning strip 312 is embedded in the positioning groove 39. Both sides of the top of the component 311 are fixedly connected to a fixing frame 313. The fixing frame 313 has a snap-fit ​​groove inside. The snap-fit ​​block 310 is snap-fitted into the snap-fit ​​groove inside the fixing frame 313.

[0020] The fixed cover 31 and the bottom cover 2 are respectively set on both sides of the support frame 11, the sealing ring 12 is embedded in the sealing groove at the bottom of the fixed cover 31 and the bottom cover 2, and the positioning rod 15 is snapped into the inside of the fixed hole 33.

[0021] Specifically, by rotating the connecting bolt 36, the connecting block 37 is moved out of the mounting bracket 38, and the fixing frames 313 on both sides of the accessory 311 are fitted onto both sides of the connecting block 37, so that the snap-fit ​​block 310 is snapped into the inside of the fixing frame 313. Then, by rotating the connecting bolt 36 in the opposite direction, the accessory 311 is moved to the side of the mounting bracket 38, and the positioning strip 312 is snapped into the positioning groove 39, so that the accessory 311 is installed on the mounting bracket 38. This facilitates the replacement of some accessories 311 inside the metal casting in the space and improves the flexibility of the metal casting.

[0022] The working process of this utility model is as follows: In use, the fixing holes 33 on the four sides of the bottom cover 2 and the top cover 3 are respectively engaged with the outer surface of the positioning rods 15 on the four sides of the support frame 11. The groove inside the conical cover 111 corresponds to the inclined surface of the inclined block 19 on the side of the movable plate 14 at both ends. When the fixing bolt 110 is rotated to move the conical cover 111 towards the movable plate 14, the inclined block 19 at both ends is limited by the conical cover 111, causing the inclined block 19 at both ends to move towards each other, thereby compressing the movable spring 18. The positioning rods 15 at both ends pull the pressing block 16 to move towards each other, so that the bottom cover 2 and the top cover 3 at both ends are fixed to the intermediate frame 1. Furthermore, by rotating the connecting bolt 36, the connecting block 37 is moved out of the mounting bracket 38, and the fixing frames 313 on both sides of the accessory 311 are fitted onto both sides of the connecting block 37, so that the snap-fit ​​block 310 is snapped into the inside of the fixing frame 313. Then, by rotating the connecting bolt 36 in the opposite direction, the accessory 311 is moved to the side of the mounting bracket 38, and the positioning strip 312 is snapped into the positioning groove 39, so that the accessory 311 is installed in the mounting bracket 38, which facilitates the replacement of some accessories 311 inside the metal casting in the space.
