[0002] Electrofused zircon corundum brick refers to a refractory product made of industrial alumina powder and selected zircon sand as raw materials, with a ZrO2 content of 33% - 45%. Electrofused zircon corundum bricks are mainly used as refractory materials for high-temperature and erosion-resistant kilns such as glass industrial tank furnaces, glass electric kiln furnaces, slideways in the steel industry, and kilns in the sodium silicate industry.

[0003] In the existing water pump industry, the volutes and impellers are mainly made of metal materials. Although these metal materials have certain mechanical strength and wear resistance, their service life is relatively short and not conducive to use. Using electrocast zircon corundum material can improve the service life of the volute and impeller, and usually, a sand mold is used for casting the water pump volute, which can improve the working efficiency.

[0004] In the actual use process, when demolding the water pump volute, steel beads are usually sprayed for demolding. However, this method will damage the surface of the water pump volute. Demolding with sandblasting steel beads will introduce tiny particles or abrasion, resulting in damage to the grain surface of the water pump volute or uneven surface quality. This kind of damage not only affects the visual appearance of the water pump volute but also its refractory performance and service life. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a casting mold for a water pump volute, aiming to improve the problems in the existing technology that steel beads are usually sprayed for demolding, which will affect the visual appearance of the water pump volute, as well as its refractory performance and service life.

A support column 9 is fixedly connected to the top of the base 1, and a plurality of anti-slip strips 2 are fixedly connected to the bottom of the base 1. The anti-slip strips 2 can facilitate the prevention of the base 1 from shifting, thereby improving the stability of the base 1. The top of the support column 9 is fixedly connected to a support plate 10. The support column 9 can facilitate the support and fixation of the support plate 10. The top of the lower mold 3 is provided with an upper mold 4. The lower mold 3 and the upper mold 4 can facilitate the casting and forming of the water pump volute. A liquid injection pipe 21 is fixedly connected to the top of the upper mold 4. The liquid injection pipe 21 can facilitate the injection of liquid into the upper mold 4 and the lower mold 3. A fixed shell 23 is fixedly connected to the middle of the lower mold 3. A fixing plate 22 is fixedly connected to the middle of the fixed shell 23. A second connecting rod 13 is rotatably connected to the middle of the fixing plate 22. The fixing plate 22 can facilitate the support of the second connecting rod 13 and can also limit the second connecting rod 13, thereby preventing the second connecting rod 13 from shifting during rotation. The top of the second connecting rod 13 is fixedly connected to a connecting plate 14. When the second connecting rod 13 rotates, it will drive the connecting plate 14 to move simultaneously. The end of the connecting plate 14 away from the second connecting rod 13 is rotatably connected to a movable rod 16. When the connecting plate 14 moves, it will drive the movable rod 16 to perform a circular motion. The top of the movable rod 16 is rotatably connected to an eccentric wheel 15. When the movable rod 16 performs a circular motion, it will drive the eccentric wheel 15 to move simultaneously. The diameter of the eccentric wheel 15 is larger than the diameter of the movable rod 16. A driving assembly is provided on the top of the base 1. The driving assembly is used to drive the second connecting rod 13 to rotate.

[0035] Refer to Figure 3 and Figure 4 As shown in, the driving assembly includes a motor 11. The motor 11 is fixedly connected to the top of the base 1. The base 1 can facilitate the support and fixation of the motor 11, thereby enabling the motor 11 to work better. The output end of the motor 11 is fixedly connected to a first connecting rod 12. When the motor 11 works, it will drive the first connecting rod 12 to rotate. The bottom of the second connecting rod 13 is fixedly connected to the top of the first connecting rod 12.

[0036] Refer to Figure 2 、 Figure 5 and Figure 6, a condensing pipe 5 and a ventilation pipe 6 are arranged inside the upper mold 4. The condensing pipe 5 can facilitate cooling after the casting of the water pump volute is completed, thereby facilitating the shaping of the water pump volute. One side of the ventilation pipe 6 is fixedly connected with a heat conducting plate 17, and a plurality of heat dissipation fins 18 are fixedly connected to the middle of the ventilation pipe 6. The heat conducting plate 17 can facilitate the conduction of the heat inside the upper mold 4 into the ventilation pipe 6, and the heat is quickly dissipated under the action of the plurality of heat dissipation fins 18, thereby improving the working efficiency. The ventilation pipe 6 is made of steel pipe to improve the heat conductivity and high temperature resistance of the ventilation pipe 6.

[0037] Working principle: When vibrating and demolding the water pump volute, the motor 11 will work. When the motor 11 works, it will drive the connecting rod 12 to rotate. When the connecting rod 12 rotates, it will drive the connecting rod 13 to rotate simultaneously. When the connecting rod 13 rotates, it will drive the movable rod 16 to move in a circular motion through the connecting plate 14. When the movable rod 16 moves in a circular motion, it will drive the eccentric wheel 15 to move simultaneously. When the eccentric wheel 15 moves, it will strike the inner wall of the fixed shell 23, thereby facilitating vibration demolding.

[0038] When dissipating heat from the water pump volute, the condensing pipe 5 will work. When the condensing pipe 5 works, it can cool the water pump volute after the casting is completed, thereby facilitating the shaping of the water pump volute. At the same time, under the action of the heat conducting plate 17, the heat inside the upper mold 4 can be conducted to the middle of the ventilation pipe 6, and when the wind passes through the middle of the ventilation pipe 6, the heat can be quickly dissipated under the action of the heat dissipation fins 18.
