Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting equipment, and particularly relates to a casting forming device for producing pump casings. Background Art
[0002] In the production process of pump casings, liquid metal is injected into a pre-designed mold, and after cooling and solidifying, a pump casing blank is formed.
[0003] In the casting process of pump casings, gravity casting equipment is used to achieve casting. The gravity casting machine is based on the gravity flow of liquid metal. By placing the molten metal at a specific height and using its own gravity, it can flow freely and fill the entire mold cavity without additional pressure, and then cool and solidify to form a casting. The mold in the gravity casting machine can be replaced according to the production workpiece. Generally, a casting port is provided on one side of the casting mold, and the gravity casting machine uses a casting groove to cooperate with the casting port to introduce the metal melt into the cavity inside the mold. Different molds have unique casting systems and structural layouts. As the key channel for liquid metal to enter the mold, the position of the liquid guiding groove needs to match the gate design of the mold to ensure that the metal liquid can flow into the mold cavity accurately without metal liquid outflow or insufficient casting. Therefore, after replacing the mold in the existing gravity casting machine, the liquid guiding groove needs to be disassembled, and then the liquid guiding groove is reassembled to a suitable position to achieve the connection between the liquid guiding groove and the casting port of the mold. However, since most liquid guiding grooves are fixedly installed on one side of the gravity casting machine or one side of the casting port of the mold by screws, this process cannot achieve convenient adjustment of the liquid guiding groove, and the installation accuracy of the liquid guiding groove is insufficient, which may cause poor metal liquid flow and defects such as insufficient casting, cold shut, and porosity.

An adjusting shaft 12 is movably connected between the liquid guiding groove 10 and the connecting seat 18.
[0023] As Figure 1 shown, a rotating shaft 13 is fixedly installed at the rear side of the lower die frame 5. Both sides of the rotating shaft 13 are rotatably installed in the shaft seats on one side of the top of the equipment frame 1. A first hydraulic rod 14 is also movably connected between the equipment frame 1 and the lower die frame 5. A top ejection mechanism 15 is fixedly installed at the bottom of the lower die frame 5. A second hydraulic rod 16 is fixedly installed at the top of the top plate 6. And the output end of the second hydraulic rod 16 passes through the top plate 6 and is fixedly connected to the upper die frame 7. And the first hydraulic rod 14, the top ejection mechanism 15 and the second hydraulic rod 16 are respectively connected to the hydraulic station 2 through pipelines;
[0024] As Figures 2-5 shown, a first guide rail 17 is fixedly installed at the front side of the lower die frame 5. Two bending plates 19 are fixedly installed at the rear side of the connecting seat 18. The two bending plates 19 are respectively fixedly installed at the front side of the slider 9. A screw hole is opened at the central position of the front side of the connecting seat 18. Through the setting of the connecting seat 18, the displacement adjustment of the liquid guiding groove 10 can be realized in cooperation with the adjusting shaft 12 and the support block 11. A bottom plate 20 is fixedly installed at the bottom of the support block 11. Two second guide rails 21 are fixedly installed at the top of the support block 11. Two supporting plates 22 are fixedly installed between one side of the support block 11 and the bottom plate 20. Through the setting of the support block 11 and the second guide rails 21 and the supporting plates 22, the liquid guiding groove 10 can be stably slidably installed on the top of the support block 11. The slider 9 is slidably installed on the first guide rail 17. Two sliding grooves 23 are opened at one side of the bottom of the liquid guiding groove 10. A fixing plate 25 is fixedly installed at the other side of the bottom of the liquid guiding groove 10. A sealing seat 24 is also fixedly installed at one side of the liquid guiding groove 10.

After the mold on the lower mold base 5 is replaced and the position of the mold casting port changes, the adjusting shaft 12 can be manually rotated. Then, one side of the second guide rail 21 rotates in the through hole in the fixing plate 25 by means of two snap rings, while the other side of the adjusting shaft 12 rotates in the threaded hole on the front side of the connecting seat 18. As a result, the adjusting shaft 12 drives the liquid guide groove 10 to move backward on the support block 11 through the fixing plate 25, thereby providing a certain space for the installation of the mold. At the same time, by cooperating with the sliding of the slider 9 on the first guide rail 17, the horizontal position of the liquid guide groove 10 can be adjusted, so that one side of the liquid guide groove 10 is aligned with the casting port of the mold. Then, in the same way as above, by rotating the adjusting shaft 12 and cooperating with the connecting seat 18 and the fixing plate 25, the liquid guide groove 10 moves towards the mold, so that the liquid guide groove 10 slides on the two second guide rails 21 on the top of the support block 11 through the two sliding grooves 23 at the bottom, and the sealing seat 24 on one side of the liquid guide groove 10 is closely attached to one side of the mold, so that the inner cavity of the liquid guide groove 10 is communicated with the casting port of the mold.
