Description

Technical Field

[0001] This utility model relates to the field of sand casting technology, and more specifically, to a sand collecting device for sand casting. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings. For a long time, it has been a fundamental process in casting production. The basic raw materials for making sand molds are foundry sand and molding sand binders. Currently, most sand casting sand collection devices commonly used in the industry adopt a structure of fixed funnels and conveyor belts. The funnels collect the sand in the drop area. However, sand is prone to accumulation and blockage inside the funnels. This blockage problem is more frequent when the sand contains a small amount of casting debris or has high moisture content, requiring regular manual cleaning, which seriously affects the continuity of production. Furthermore, the funnel discharge can easily lead to localized sand accumulation, making it difficult to collect the sand. Utility Model Content

[0013] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0014] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a sand collecting device for sand casting, including a movable base box 1, a swing structure 2 and a feeding device 3. The top of the left end of the movable base box 1 is fixedly connected to the swing structure 2, and the feeding device 3 is rotatably installed on the upper end of the swing structure 2. like Figure 3 As shown, the swing structure 2 includes a fixed frame 21 and a limiting device 27. A support block 22 is fixedly connected to one end of the bottom of the fixed frame 21, and the limiting device 27 is fixedly connected to the top of the fixed frame 21. A rotary motor 23 is fixedly connected to one side of the upper end of the fixed frame 21. A rotating disk 24 is fixedly connected to the output end of the rotary motor 23. A support frame 25 is fixedly connected inside the rotating disk 24. An movable hole 26 is opened inside one end of the support frame 25. The rotating disk 24 is rotatably mounted on the side of the fixed frame 21.

[0015] like Figure 4As shown, the limiting device 27 includes an arc-shaped frame 271. One end of the arc-shaped frame 271 is fixedly connected to a top frame 273, which is fixedly installed on the top of the fixed frame 21. A limiting ring 272 is fixedly connected inside the arc-shaped frame 271. A limiting groove 274 is opened inside the end of the limiting ring 272 near the arc-shaped frame 271. Movable frames 277 are movably sleeved on both sides of the arc-shaped frame 271. A connecting plate 275 is fixedly connected to the side of the movable frame 277. A pressing wheel 276 is rotatably installed on the side of the connecting plate 275. A return spring 278 is movably sleeved on the outer surface of the movable frame 277. The return spring 278 is located between the inner wall of the arc-shaped frame 271 and the connecting plate 275.

[0016] like Figure 5 As shown, the feeding device 3 includes a feeding hopper 31 and a feeding pipe 32. A rotating column 33 is fixedly connected to the bottom of the feeding hopper 31. Side rods 34 are fixedly connected to both sides of the upper end of the rotating column 33. A rotating frame 35 is rotatably mounted on the outer surface of the side rods 34 at both ends. A connecting rod 36 is fixedly connected to the side of the rotating frame 35. A ball bearing 37 is fixedly connected to one end of the connecting rod 36.

[0017] Among them, the rotating column 33 is rotatably installed inside the support block 22, the feed hopper 31 is rotatably installed inside the limiting ring 272, the protrusion 38 is movably installed inside the limiting groove 274, the extrusion wheel 276 is movably installed on the side of the protrusion 38, the ball 37 is rotatably installed inside the movable hole 26, and the protrusion 38 is fixedly connected to the lower end of the feed hopper 31 away from the feed pipe 32.

[0018] Specifically, the rotary motor 23 controls the rotating disk 24 to rotate, and the support frame 25 rotates. Through the limiting of the movable hole 26, one end of the connecting rod 36 is pulled, causing the ball 37 to rotate inside the movable hole 26. The movable hole 26 changes position as the rotating disk 24 rotates, and pulls the rotating frame 35 to rotate, causing the rotating frame 35 to rotate on the outer surface of the side rod 34. Through the orientation of the connecting rod 36, the rotating column 33 reciprocates inside the support block 22, thereby causing the feed pipe 32 to swing back and forth, achieving uniform feeding of sand.

[0019] In addition, the limiting ring 272 limits the feed hopper 31. As the feed hopper 31 reciprocates inside the limiting ring 272, the protrusion 38 reciprocates inside the limiting groove 274. At this time, by setting the return spring 278 and the extrusion wheel 276, when the protrusion 38 moves to the side of the extrusion wheel 276, the return spring 278 is compressed, and the extrusion wheel 276 moves to the side. After the protrusion 38 passes the extrusion wheel 276, the reaction force of the return spring 278 causes the extrusion wheel 276 to strike the side of the feed hopper 31 through the limiting groove 274, causing the feed hopper 31 to vibrate, so that the sand is discharged quickly and avoids sand blockage, which would affect the sand discharge.

[0020] like Figure 2 As shown, the movable base box 1 includes a sliding base 11 and a collection box 19. A rotary motor 14 is fixedly connected to the left end of the sliding base 11, and a reciprocating screw 15 is fixedly connected to the output end of the rotary motor 14. A sliding groove 12 is provided inside the sliding base 11. Multiple auxiliary rollers 16 are rotatably installed on both sides of the top of the sliding base 11. The reciprocating screw 15 is rotatably installed inside the sliding groove 12. A moving block 17 is threaded on the outer surface of the reciprocating screw 15. A fixed block 18 is fixedly connected to the top of the moving block 17. The moving block 17 is slidably installed inside the sliding groove 12. A body frame 13 is fixedly connected to the left side of the top of the sliding base 11.

[0021] The collection box 19 is slidably mounted on the top of the auxiliary roller 16, and a positioning groove 110 is provided at the bottom of the collection box 19. The positioning groove 110 is movably sleeved on the outer surface of the fixing block 18.

[0022] Specifically, the positioning groove 110 is fitted onto the outer surface of the fixing block 18, and the collection box 19 is placed on top of the auxiliary roller 16. At this time, the rotating motor 14 controls the reciprocating screw 15 to rotate, so that the moving block 17 slides inside the sliding groove 12 and drives the collection box 19 to move on top of the auxiliary roller 16. This controls the collection box 19 to move below the feeding device 3, making it easier for the feeding device 3 to feed the sand to different positions inside the collection box 19, making the sand feeding more uniform. At the same time, the collection box 19 is easy to remove from the top of the moving block 17, making it easier to remove the collection box 19.

[0023] The working process of this utility model is as follows: In use, sand and gravel are fed into the feed hopper 31 and discharged through the discharge pipe 32. During the discharge of sand and gravel, the rotating motor 14 controls the reciprocating screw 15 to rotate, causing the moving block 17 to slide inside the sliding groove 12 and drive the collection box 19 to move on top of the auxiliary roller 16, thereby controlling the collection box 19 to reciprocate below the discharge device 3. The discharge device 3 discharges material at different positions inside the collection box 19. Simultaneously, the rotary motor 23 controls the rotating disk 24 to rotate, and the support frame 25 rotates. Through the limiting position of the movable hole 26, one end of the connecting rod 36 is pulled, causing the ball bearing 37 to rotate inside the movable hole 26. The movable hole 26 changes position as the rotating disk 24 rotates, pulling the rotating frame 35 to rotate. This causes the rotating frame 35 to rotate on the outer surface of the side rod 34. Through the orientation of the connecting rod 36, the rotating column 33 reciprocates inside the support block 22, thereby causing the feed pipe 32 to swing back and forth. The limiting ring 272 limits the feed hopper 31. As the feed hopper 31 reciprocates within the limiting ring 272, the protrusion 38 reciprocates within the limiting groove 274. At this time, by setting a return spring 278 and a pressing wheel 276, when the protrusion 38 moves to the side of the pressing wheel 276, the return spring 278 is compressed, and the pressing wheel 276 moves to the side. After the protrusion 38 passes the pressing wheel 276, the reaction force of the return spring 278 causes the pressing wheel 276 to strike the side of the feed hopper 31 through the limiting groove 274, causing the feed hopper 31 to vibrate and the sand to be discharged quickly.
