Technical Field

[0001] This application relates to the field of impeller casting devices, and particularly to an impeller casting device with a grinding mechanism. Background Art

[0002] The impeller is a key component of a centrifugal pump, which is composed of several curved blades. The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid to increase the static pressure energy and dynamic pressure energy of the liquid (mainly to increase the static pressure energy). The impeller is usually cast using a casting mold.

[0003] After the existing impeller castings are produced, they need to be ground separately. Usually, manual grinding is used for the operation, but the efficiency of manual grinding is low and the grinding operation is rather inconvenient. Utility Model Content

[0004] In order to solve the problems of low efficiency and inconvenient grinding operation of manually grinding impellers, this application provides an impeller casting device with a grinding mechanism.

A driving component for driving the support frame to move is arranged on the workbench. A pushing component for ejecting the impeller is arranged on one side of the concave mold.

[0007] By adopting the above technical solutions, after the impeller is cast and removed from the mold, the hydraulic component drives the convex mold and the concave mold to separate. At this time, the pushing component on one side of the concave mold ejects the impeller casting from the concave mold. The driving component drives the support frame to move to the position of the impeller casting. At this time, the rotating member is attached to one side of the impeller casting. The rotating member rotates to drive the impeller casting to rotate, and at the same time, the grinding mechanism grinds the impeller casting, and the grinding operation is rather convenient.

[0011] By adopting the above technical solution, the first spring presses the second grinding plate tightly, and the second grinding plate elastically presses against both sides of the impeller casting for grinding. It is not easy to cause damage due to the second grinding plates on both sides clamping the impeller casting. At the same time, by rotating the screw rod to push the sliding plate to slide, the compression amount of the first spring is adjusted, and thus the pressing degree of the second grinding plate is adjusted.

[0019] By adopting the above technical solution, when the hydraulic cylinder drives the concave mold to move, the push rod pushes the impeller casting out of the concave mold.

Detailed Description of the Invention

[0032] The following further details the present application with reference to the accompanying drawings.

[0033] An embodiment of the present application discloses an impeller casting device with a grinding mechanism. Referring to Figure 1 and Figure 2 , it includes a frame 1. A workbench 2 is arranged on the frame 1. A convex mold 3 and a concave mold 4 adapted to the convex mold 3 are arranged on the workbench 2. The concave mold 4 is arranged opposite to the convex mold 3. A hydraulic component 5 for driving the convex mold 3 and the concave mold 4 to move is arranged on the workbench 2.

[0034] Referring to Figure 1 and Figure 2 , a support frame 23 is slidably mounted on the workbench 2. A grinding mechanism 6 and a rotating part 7 are arranged on the support frame 23. A driving part for driving the support frame 23 to move is arranged on the workbench 2. A pushing part 9 for ejecting the impeller is arranged on one side of the concave mold 4. When the impeller is cast and removed from the mold, the hydraulic component 5 drives the convex mold 3 and the concave mold 4 to separate. At this time, the pushing part 9 on one side of the concave mold 4 pushes the impeller casting out of the concave mold 4. The driving part drives the support frame 23 to move to the position of the impeller casting. At this time, the rotating part 7 is attached to one side of the impeller casting. The rotating part 7 rotates to drive the impeller casting to rotate. At the same time, the grinding mechanism 6 grinds the impeller casting, and the grinding operation is relatively convenient.

[0035] Referring to Figure 2The hydraulic component 5 includes a hydraulic cylinder 51 and a sliding rod 52. A mounting frame 21 is provided on the workbench 2. The sliding rod 52 is horizontally slidably installed on the mounting frame 21. The hydraulic cylinder 51 is provided on the workbench 2. A connecting plate 521 is provided at one end of the sliding rod 52. The connecting plate 521 is connected to one end of the piston rod of the hydraulic cylinder 51.

[0036] Reference Figure 2 A mounting plate 53 is provided at one end of the sliding rod 52 away from the connecting plate 521, and the concave mold 4 and the convex mold 3 are arranged on a side surface of the mounting plate 53 away from the sliding rod 52. The hydraulic cylinder 51 pushes the sliding rod 52 to drive the mounting plate 53 to move, thereby driving the concave mold 4 and the convex mold 3 to move.

[0037] Reference Figure 2 The pusher 9 includes a push rod 91 and a push rod 92, which are both horizontally arranged on the side of the mounting frame 21 facing the mounting plate 53. The push rod 91 and the push rod 92 are slidably connected with the mounting plate 53. The designer has a through hole 41 on the female mold 4 for the push rod 91 and the push rod 92 to pass through. The end of the push rod 91 away from the mounting plate 53 is located at the middle hole of the impeller casting. The hydraulic cylinder 51 drives the female mold 4 to move, and the push rod 92 pushes the impeller casting out of the female mold 4. The impeller casting is located at one end of the push rod 91.

[0038] Reference Figure 2 The push rod 92 is sleeved with a second spring 93, one end of the second spring 93 is connected to one side of the mounting plate 53, and the end of the second spring 93 away from the mounting plate 53 is connected to one side of the mounting frame 21. When the sliding rod 52 drives the mounting plate 53 to move, the second spring 93 is pushed and compressed by the mounting plate 53. When the mold needs to be closed, the second spring 93 stretches and recovers. During the sliding process of the mounting plate 53, the second spring 93 buffers the mounting plate 53 to reduce the probability of the mounting plate 53 shaking.

[0040] Reference Figure 3, the rotating member 7 includes a motor 71 and a rotating wheel 72. The motor 71 is arranged on the support frame 23. The rotating wheel 72 is rotatably installed on the support frame 23 and connected to the output shaft of the motor 71. There are two rotating wheels 72 and they are located on both sides of the support frame 23. During operation, the driving cylinder 8 drives the support frame 23 to move to the position of the impeller casting. At this time, the rotating wheels 72 are in contact with the circumferential side wall of the impeller casting. The motor 71 drives the rotating wheels 72 to rotate, and the rotating wheels 72 on both sides drive the impeller casting to rotate.

[0041] Referring to Figure 3 , the grinding mechanism 6 includes a first grinding plate 61 and a second grinding plate 62. An installation block 24 is arranged on the support frame 23. The first grinding plate 61 is arranged on the installation block 24. One side surface of the first grinding plate 61 is in contact with the circumferential side wall of the impeller casting. The second grinding plate 62 is vertically arranged on the installation block 24 and is located on both opposite sides of the first grinding plate 61. The second grinding plate 62 is in contact with both side surfaces of the impeller casting. When the impeller casting rotates, the first grinding plate 61 grinds the circumferential side wall of the impeller casting, and the second grinding plate 62 grinds both side surfaces of the impeller casting.

[0042] Referring to Figure 3 and Figure 4 , sliding grooves 241 are arranged on both sides of the installation block 24 where the first grinding plate 61 is located. The second grinding plate 62 is slidably installed at the sliding grooves 241. A sliding plate 242 and a screw 243 are arranged on the installation block 24 at the sliding grooves 241. The screw 243 is threadedly installed on the installation block 24 and one end is located inside the sliding groove 241. The sliding plate 242 is slidably installed at the sliding groove 241 and is rotatably connected to one end of the screw 243. Four first springs 244 are arranged between the sliding plate 242 and the second grinding plate 62. The first springs 244 press the second grinding plate 62 tightly. The second grinding plate 62 elastically presses against both side surfaces of the impeller casting for grinding, and it is not easy to have the problem that the second grinding plates 62 on both sides clamp the impeller casting and cause damage. At the same time, by rotating the screw 243 to push the sliding plate 242 to slide, the compression amount of the first springs 244 is adjusted, and thus the pressing degree of the second grinding plate 62 is adjusted.

[0043] Referring to Figure 3 , a connecting rod 245 is arranged on the lower side surface of the installation block 24. The connecting rod 245 is slidably installed on the support frame 23. A locking bolt 246 is arranged on the support frame 23. Slide the connecting rod 245 and lock it with the locking bolt 246 to adjust the height of the installation block 24, and thus adjust the heights of the first grinding plate 61 and the second grinding plate 62, which is suitable for grinding impeller castings with different radii.

[0044] The implementation principle of an impeller casting device with a grinding mechanism in an embodiment of the present application is as follows: After the impeller is cast and removed from the mold, the hydraulic cylinder drives the convex mold 3 and the concave mold 4 to separate. At this time, the push rod 92 on one side of the concave mold 4 pushes the impeller casting out of the concave mold 4. The driving cylinder 8 drives the support frame 23 to move to the position of the impeller casting. At this time, the rotating wheel 72 is attached to the circumferential side wall of the impeller casting and drives the impeller casting to rotate. At the same time, the first grinding plate 61 and the second grinding plate 62 grind the impeller casting, and the grinding operation is relatively convenient.
