Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal casting, in particular to a power fitting forming device. BACKGROUND

[0002] As a kind of metal casting process, die casting can quickly produce high-precision and complex-shaped castings by injecting molten metal into a mold cavity under high pressure. Power fittings, as metal accessories used in power systems for connecting, fixing and protecting wires, cables, insulators, towers and other power equipment, are critical components that ensure the safe and stable operation of power transmission and distribution systems. They have various structures, such as the arc-shaped slot of a wire clamp, the ring-shaped structure of a hanging ring, and the irregular counterweight of a vibration damper, which all require precise shaping through die casting molds to ensure a tight fit with matching components such as wires and insulators, avoiding problems such as looseness or poor contact. However, in the existing die casting process of power fittings, the die casting parts in the mold gradually cool and form under pressure, and thermal stress is generated inside the casting during the cooling process. Therefore, the die casting parts need to be left in the mold for a certain period to allow the stress to slowly release, thereby reducing deformation and cracks caused by stress concentration. However, this prolonged stay of the die casting parts in the mold results in longer downtime during mold replacement, increasing the production time of the die casting parts and affecting the forming efficiency of the power fittings.

[0055] In use;

[0056] Reference Figure 1 and Figure 2 As shown in the drawings, when one of the molds 12 needs to be cooled and the other mold 12 needs to be die-cast, the first servo motor 25 drives the support plate 23 to rotate along the top end of the support stand 22, and then the support plate 23 drives the flow ring 24 to rotate along the outside of the support stand 22. At this time, the flow ring 24 drives one of the molds 12 to rotate along the bottom of the die-casting machine 11, so that the one mold 12 is offset from the die-casting machine 11, and the other mold 12 moves along the top of the stabilizing ring frame 1 to the bottom of the die-casting machine 11, and the two molds 12 are alternately operated with the die-casting machine 11.

[0057] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown in the drawings, when one of the molds 12 needs to be cooled and the other mold 12 needs to be die-cast, the first servo motor 25 drives the support plate 23 to rotate along the top end of the support stand 22, and then the support plate 23 drives the flow ring 24 to rotate along the outside of the support stand 22. At this time, the flow ring 24 drives one of the molds 12 to rotate along the bottom of the die-casting machine 11, so that the one mold 12 is offset from the die-casting machine 11, and the other mold 12 moves along the top of the stabilizing ring frame 1 to the bottom of the die-casting machine 11, and the two molds 12 are alternately operated with the die-casting machine 11.

[0058] Reference Figure 1 , Figure 2 and Figure 3 As shown in the drawings, when one of the molds 12 moves along the top of the stabilizing ring frame 1 to the bottom of the die-casting machine 11, first, the flow frame 21 makes a circular motion along the top end of the stabilizing ring frame 1, and then drives the bottom of the centering groove 41 to move to the positioning frame 44. With the continuous movement of the centering taper plate 42, the other centering taper plate 42 is pushed to move close to the positioning frame 44. Due to the gap between the other centering taper plate 42 and the positioning frame 44, the reset spring 45 is reset by its own elasticity, thereby generating an upward pushing force on the bottom of the positioning frame 44, causing the top of the positioning frame 44 to collide with the bottom of the other centering taper plate 42 and emit a sound, so that the gap between the positioning frame 44 and the other centering taper plate 42 is complemented under the action of the reset spring 45, and finally the two form precise positioning cooperation.

[0059] ReferenceFigure 1 、 Figure 9 and Figure 10 When the die casting inside the mold 12 achieves the pre-separation tendency and the rest of the mold 12 is located below the die casting machine 11, first, the mold 12 which has completed the turnover carries the die casting to move along the top end of the stabilizing ring frame 1, and the mold 12 smoothly passes through the guide moving groove 62, while the rest of the mold 12 is located below the die casting machine 11, at this time, the mold 12 which is to be die cast and the mold 12 which is to be taken out are kept in a stable state, then the lifting assembly drives the flexible connecting frame 61 to keep a distance from the mold 12 which can allow the die casting to fall, which can facilitate the die casting to be taken out from the cavity of the mold 12 and collected and stored, and can guide the die casting to move along the predetermined path through the guide effect of the flexible connecting frame 61.
