[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 , an overflowable impeller forming mold, including a lower mold 1, an upper mold 2 is provided on the top of the lower mold 1, and a connecting seat 3 is provided on the top of the upper mold 2. The outer walls of both sides of the lower mold 1 are fixed with lower electric push rods 4 by bolts, and the top of the lower electric push rod 4 is fixedly connected to the upper mold 2, and two upper electric push rods 5 are fixed to the top of the upper mold 2 by bolts. The top of the upper electric push rod 5 is fixedly connected to the connecting seat 3. An overflow channel 6 is provided between the upper mold 2 and the connecting seat 3. The excess molten metal flows into the overflow channel 6 and then is discharged through the overflow channel 6, thereby improving the forming effect of the impeller. A plurality of inner bearing blocks 7 are welded on the bottom of the connecting seat 3, and the inner bearing blocks 7 are located in the overflow channel 6. A plurality of pads 8 are welded on the circumferential outer wall of the connecting seat 3, and the pads 8 are located at the top of the upper mold 2. The connecting seat 3 is supported by the inner bearing blocks 7 and the pads 8 to form an overflow channel 6.

[0025] The lower mold 1 is provided with a ejector assembly 9, which includes an ejector plate 901. The ejector plate 901 slides in the lower mold 1. A plurality of connecting ejectors 902 are welded on the top of the ejector plate 901. The tops of the connecting ejectors 902 pass through the top of the lower mold 1. The bottom of the lower mold 1 is fixed with an oil cylinder 10 by bolts. One end of the piston rod of the oil cylinder 10 is fixedly connected to the ejector plate 901. Driven by the oil cylinder 10, the ejector plate 901 moves upward, thereby driving the connecting ejector 902 to move upward, thereby ejecting the formed impeller out of the lower mold 1. The bottom of the lower mold 1 is fixed with two support seats 11 by bolts. A plurality of vertical rods 12 are welded on the bottom of the support seat 11. The lower mold 1, the upper mold 2 and the connecting seat 3 are slidably connected with the vertical rods 12. The movement of the lower mold 1, the upper mold 2 and the connecting seat 3 is guided by the vertical rods 12. The bottoms of the two support seats 11 are jointly fixed with a base 13 by bolts, and a plurality of reinforcing ribs are welded on one side of the support seat 11.

[0026] The working principle of this embodiment is as follows: when in use, first, the upper mold 2 and the lower mold 1 are brought together under the drive of the contraction of the lower electric push rod 4. Then, the molten metal is injected into the upper mold 2 and the lower mold 1 from the pouring port of the upper mold 2. The excess molten metal flows into the overflow channel 6 and is then discharged through the overflow channel 6, thereby improving the molding effect of the impeller.

[0027] After molding, the upper mold 2 and the lower mold 1 are separated under the stretching of the lower electric push rod 4, and then, the ejector plate 901 is driven upward by the oil cylinder 10, thereby driving the connecting ejector 902 to move upward, thereby ejecting the formed impeller out of the lower mold 1. When the overflow channel 6 needs to be cleaned, the connecting seat 3 is separated from the upper mold 2 under the stretching of the upper electric push rod 5, thereby facilitating the cleaning of the molten metal in the overflow channel 6.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
