Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy casting, in particular to a production device for aluminum alloy casting. Background Art

[0002] During the aluminum alloy casting process, the alloy is placed in a high-temperature furnace for melting. The melting temperature is usually between 660°C and 800°C. The temperature needs to be controlled during the melting process to prevent the separation and deterioration of the alloy components. Subsequently, the molten aluminum alloy liquid is quickly poured into a pre-made mold; the casting is cooled in the mold, which usually takes a certain amount of time to ensure that the internal structure of the casting is uniform; after the casting is cooled, it is taken out of the mold for subsequent processing.

[0003] Moreover, in the existing aluminum alloy casting process, for example, in the process of casting a large flange, after the staff pours the aluminum alloy liquid into the mold through a pouring spoon, and after cooling and forming, when the upper mold and the lower mold are separated, although the existing hydraulic cylinder is used to demold the upper mold, and after demolding, the large flange is affected by the upper mold pouring port, that is, aluminum alloy residue remains near the pouring port, causing the large flange to move up synchronously with the upper mold. When the upper mold and the lower mold are completely separated, the staff needs to use tools to knock between the upper mold and the large flange for demolding. In this process, on the one hand, when the staff knocks on one point of the flange, it is easy to cause the large flange to be stuck on the upper mold, which not only easily causes deformation of the large flange, but also easily causes deformation of the upper mold, thereby affecting the production of the large flange. For this reason, we propose a production device for aluminum alloy casting. Summary of the invention

[0066] Specific implementation process: During the casting process of the large aluminum alloy flange between the upper mold 3 and the lower mold 2, the upper top plate 71 and the lower fixing ring 72 at the connecting plate 73 on the rotating rod 5 are both deviated from the position of the casting workbench 1. After the large flange is cast and the upper mold 3 and the lower mold 2 are demoulded, the large flange is affected by the multiple pouring ports 31 at the top of the upper mold 3. After the large flange moves up together with the upper mold 3, the connecting plate 73 is driven to rotate by the rotating rod 5, and the upper top plate 71 and the lower fixing ring 72 are further rotated to the side close to the casting workbench 1.

[0067] Subsequently, by rotating the motor 7661, the synchronous gear 7662 further drives the two first connecting shafts 763 to rotate synchronously, and when the two first connecting shafts 763 rotate, the first rotating gear 761 thereon is driven to rotate, and when the first rotating gear 761 rotates, due to the limiting effect of the gear groove 781 on the connecting rod 78, the connecting rods 78 at the two first connecting sleeves 74 drive the top plate 71 to move along the casting workbench 1, and when the first connecting shaft 763 rotates, the second connecting shaft 764 at the bottom is driven to rotate through the sliding sleeve 7651 and the sliding rod 7652, thereby causing the two second rotating gears 762 to rotate synchronously;

[0068] Then, the two connecting rods 78 at the two second connecting sleeves 75 drive the lower fixed ring 72 to move along the casting workbench 1 until the upper top plate 71 moves to directly above the upper mold 3, and the lower fixed ring 72 moves to directly below the large flange. At this time, the hydraulic cylinder 772 is operated to drive the two second connecting sleeves 75 to move upward along the connecting plate 73 through the moving plate 771. At the same time, the connecting rod 78 at the second connecting sleeve 75 drives the lower fixed ring 72 thereon to move upward along the bottom of the large flange, thereby facilitating the lower fixed ring 72 to connect the large flange.

When the push block 85 moves downward along the pouring port 31 and pushes the end of the large flange located at the pouring port 31 downward, the push rod 87 moves downward synchronously. When the conical block 865 at the push rod 87 contacts the conical ends 8621 at the four moving frames 862, the four moving frames 862 are moved in directions away from each other. When the moving frames 862 move, the multiple scrapers 861 are synchronously moved in directions away from each other. Furthermore, the four scrapers 861 scrape off the aluminum alloy residue on the outside of the pouring port 31 of the upper mold 3.

[0078] At the same time, after the lower fixing ring 72 receives the large aluminum alloy flange, the four connecting rods 78 are retracted and the rotating rod 5 is rotated to further rotate the lower fixing ring 72 to the side away from the casting workbench 1, so as to facilitate the staff to quickly take out the material.

[0079] Embodiment 2

[0080] See also Fig.10 , Embodiment 2 is a further supplementary description of Embodiment 1, specifically: a positioning material receiving mechanism 9 is provided on the lower fixing ring 72, and the positioning material receiving mechanism 9 stably receives the large flange, and the positioning material receiving mechanism 9 includes a plurality of supporting springs 91 installed at the bottom of the lower fixing ring 72, and a supporting plate 92 is fixedly installed on the top of the plurality of supporting springs 91, and a groove matching the bottom of the large flange is provided on the supporting plate 92;

[0081] Therefore, when the large flange detaches from the upper mold 3 and falls onto the lower fixing ring 72, the support plate 92 can support the large flange. At the same time, the provision of multiple support springs 91 can further play a buffering role, thereby ensuring the stability of the support of the lower fixing ring 72.
