Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figures 1 - 3 As shown in [figure reference], an embodiment provided by the present utility model: a sand mold for casting the fused zirconia corundum water pump impeller, including a base 1, the top of the base 1 is fixedly connected with a lower sand mold 2, two limit grooves 5 are respectively opened in the left and right sides of the lower sand mold 2, a spring 6 is fixedly connected inside the limit groove 5, one end of the spring 6 is fixedly connected with a limit block 7, a clamping block 8 is fixedly connected to the outside of the limit block 7, insert slots 11 are respectively opened at the four corners of the top of the lower sand mold 2, an upper sand mold 3 is arranged on the top of the lower sand mold 2, insert rods 10 are respectively fixedly connected to the four corners of the bottom of the upper sand mold 3, a card slot 9 is opened inside the insert rod 10, a water cooling component is arranged outside the base 1, and the water cooling component is used for cooling the casting. Electric push rods 12 are respectively installed on the left and right sides of the top of the base 1, the output end of the electric push rod 12 is fixedly connected with a moving plate 13, the limit block 7 is slidably connected inside the limit groove 5, and an L-shaped rod 14 is fixedly connected to the bottom of the limit block 7.
[0024] Specifically, the base 1 can support and fix the lower sand mold 2, thereby maintaining stability during casting. By pushing the moving plate 13 with the electric push rod 12, the L-shaped rod 14 can slide inside the lower sand mold 2, which can drive the limit block 7 to slide inside the limit slot 5 and press the spring 6 to contract. The limit slot 5 can restrict the movement of the limit block 7 to keep it moving horizontally. At this time, the upper sand mold 3 is placed on the top of the lower sand mold 2. Then, by inserting the insertion rod 10 into the insertion slot 11 opened at the top of the lower sand mold 2 correspondingly, and through the contraction of the electric push rod 12, the spring 6 can rebound, thereby pushing the limit block 7 and driving the clamping block 8 to move, so that the clamping block 8 is inserted into the clamping slot 9 opened on the insertion rod 10, which can fix the upper sand mold 3, making the lower sand mold 2 and the upper sand mold 3 closely connected during casting without deviation, ensuring the casting quality of the casting and improving the casting effect of the casting.
[0025] Refer to Figure 2 , the water cooling component includes a cooling water tank 15, the cooling water tank 15 is fixedly connected to the rear side of the base 1, a circulating pump 16 is fixedly connected to the outer side of the cooling water tank 15, the output end of the circulating pump 16 is fixedly connected to a water outlet pipe 19, one end of the water outlet pipe 19 is fixedly connected to a serpentine pipe 17, the other side of the cooling water tank 15 is fixedly connected to a return pipe 18, one end of the return pipe 18 is fixedly connected to the other end of the serpentine pipe 17, and the serpentine pipe 17 is fixedly connected inside the base 1.
[0026] Specifically, the circulating pump 16 is fixed to the rear side of the base 1 to keep it stable during operation. By starting the circulating pump 16, the circulating pump 16 conveys the cooling water in the cooling water tank 15 into the water outlet pipe 19, then into the serpentine pipe 17, and finally returns to the cooling water tank 15 through the return pipe 18. The serpentine pipe 17 is fixed inside the base 1 below the lower sand mold 2, realizing the water circulation cooling of the mold, thereby accelerating the forming speed of the casting and avoiding the risk of workers being scalded when taking out the casting.
[0027] Refer to Figure 3 , the L-shaped rod 14 is slidably connected inside the lower sand mold 2, the outside of the L-shaped rod 14 is in contact with the moving plate 13, the clamping block 8 is engaged with the inside of the clamping slot 9, and the outside of the insertion rod 10 is slidably connected to the inside of the insertion slot 11.
[0028] Specifically, the movement of the L-shaped rod 14 can drive the limit block 7 to move, thereby compressing the spring 6. At the same time, the L-shaped rod 14 is in contact with the moving plate 13. When the electric push rod 12 contracts, the L-shaped rod 14 will lose pressure and the spring 6 will rebound, thereby pushing the clamping block 8 to engage with the clamping slot 9 to restrict the movement of the insertion rod 10. Through the insertion and cooperation of the insertion rod 10 and the insertion slot 11, the upper sand mold 3 is fixed to ensure that there is no deviation during casting.
[0029] Referring to Figure 1 , on both the left and right outer sides of the upper sand mold 3, two handle grips 20 are fixedly connected. Anti-slip patterns are provided on the outer sides of the handle grips 20, and a casting pipe 4 is fixedly connected to the top of the upper sand mold 3.
[0030] Specifically, the handle grips 20 facilitate the worker to remove the upper sand mold 3 from the top of the lower sand mold 2, and the anti-slip patterns provided on the surface can prevent hand slipping and ensure stable gripping. The casting raw materials can be injected into the mold through the casting pipe 4 to realize the casting operation.
[0031] Working principle: When using the mold for casting, the electric push rods 12 on both the left and right sides of the top of the base 1 can be used to push the moving plate 13 to move, so that the L-shaped rod 14 slides inside the lower sand mold 2, which can drive the limit block 7 to slide inside the limit groove 5 and press the spring 6 to contract. At this time, the upper sand mold 3 is placed on the top of the lower sand mold 2, and the insertion rod 10 is correspondingly inserted into the insertion slot 11 opened on the top of the lower sand mold 2. Then, the electric push rod 12 is contracted, so that the spring 6 can rebound, thereby pushing the limit block 7 and driving the clamping block 8 to move, so that the clamping block 8 is inserted into the clamping groove 9 opened on the insertion rod 10, which can realize the fixation of the upper sand mold 3, making the lower sand mold 2 and the upper sand mold 3 closely connected during casting without deviation, ensuring the casting quality of the casting and improving the casting effect of the casting. Secondly, after adding the raw materials to the mold through the casting pipe 4, the circulating pump 16 can be started, so that the circulating pump 16 conveys the cooling water in the cooling water tank 15 to the water outlet pipe 19, then enters the serpentine pipe 17, and finally returns to the cooling water tank 15 through the return pipe 18, realizing the water circulation cooling of the mold, thereby accelerating the forming speed of the casting and at the same time avoiding the risk of the worker being scalded when taking out the casting.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
