Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a demolding machine for cylindrical castings. Background Technology

[0002] Casting demolding refers to the process of removing a solidified casting from a casting mold during the casting process.

[0003] Patent CN219335943U discloses a casting demolding vibrating shell machine. It includes a support plate with two opposing clamping plates on its upper surface that can move left and right. A cleaning plate that can move back and forth is located on the rear side of the upper surface of the support plate. A vibrating rod that can move up and down is located above the support plate between the two clamping plates. A cleaning brush is located at the bottom of the cleaning plate, and a stop plate is connected to its front side via an elastic component. When using this patent, the mechanical parts and mold to be demolded are placed in the middle of the upper surface of the support plate. A second cylinder moves the clamping plates to clamp the mechanical parts and mold. Then, a first cylinder moves the vibrating rod downwards, causing it to contact the mechanical parts and mold. The vibration of the vibrating rod ultimately loosens the mechanical parts and mold. However, this existing patent using vibration for demolding has some shortcomings. Demolding requires force in a specific direction, while vibration is dispersed in multiple directions, easily leading to uneven stress on the casting, incomplete demolding, and localized residue.

[0004] Therefore, there is a need for a stable axial demolding machine for cylindrical castings. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents that use vibration for demolding, which require force in a specific direction and are dispersed in multiple directions, leading to uneven stress on the casting and problems such as incomplete demolding and local residue, this utility model provides a cylindrical casting demolding machine for stable axial demolding.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a cylindrical casting demolding machine, comprising a support frame, a pallet, conveying rollers, a baffle, a casting mold, a cylindrical casting, guide rails, an adjusting screw, a guide rod, a slider, a first guide roller, and a second guide roller. The pallet is fixedly connected to the support frame, and multiple conveying rollers are rotatably mounted on the support frame. A baffle is fixedly connected to the support frame, and the casting mold is mounted on the pallet. A cylindrical casting is placed inside the casting mold. Guide rails are fixedly connected to the support frame, with an adjusting screw rotatably mounted inside one guide rail and a guide rod fixedly connected to the other guide rail. The adjusting screw is threaded with a slider, and the guide rod is slidably equipped with another slider. The sliders slide within adjacent guide rails. A first guide roller is rotatably mounted between the two sliders, and a second guide roller is rotatably mounted on the guide rails. The system also includes a servo motor, a take-up roller, a pull rod, a threaded joint, a push plate, a pull ring, and a pull rope. The servo motor is installed inside the support frame, and the take-up roller is mounted on the output shaft of the servo motor via a coupling. A pull rod is installed inside the cylindrical casting, and a pull ring is mounted on the pull rod. A pull rope is connected to the pull ring, and a threaded joint is threaded on the pull rod. A push plate is fixedly connected to the threaded joint.

[0007] Furthermore, it is particularly preferred that the assembly also includes a threaded portion, a fixed bracket, a sliding bracket, a scissor bracket, a top block, and an adjusting nut. The pull rod is provided with a threaded portion, and a fixed bracket is fixedly connected to the pull rod. A sliding bracket is threaded onto the threaded portion of the pull rod. Three scissor brackets are provided between the sliding bracket and the fixed bracket. Top blocks are provided at both ends of the scissor brackets. An adjusting nut is threaded onto the pull rod.

[0008] Furthermore, it is particularly preferred that the device also includes a mounting bracket, a roller, and a bidirectional screw. The support plate has four guide grooves, and the bidirectional screw is rotatably mounted on the support plate. Two mounting brackets are threaded onto the bidirectional screw, and rollers are rotatably mounted on the mounting brackets.

[0009] Furthermore, it is particularly preferred that the screw also includes a knob, which is fixedly connected to the bidirectional screw.

[0010] In addition, it is particularly preferable that the knob has anti-slip texture.

[0011] Furthermore, it is particularly preferred that the baffle blocks the casting mold while allowing the cylindrical casting to pass through.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the servo motor, the output shaft of the servo motor drives the winding roller to rotate and tighten the pull rope. The pull rope passes around the first guide roller and the second guide roller, and transmits the force to the pull rod. The pull rod moves to the right under the traction of the pull rope. As the push plate at its left end is pressed and contacted with the left end face of the cylindrical casting, it provides a pulling force to smoothly pull the cylindrical casting out of the stationary casting mold.

[0013] 2. By rotating the adjusting nut, the adjusting nut drives the pull rod to rotate. The threaded part of the pull rod drives the sliding frame to move, so that the sliding frame and the scissor frame on the fixed frame unfold, pushing the top blocks at both ends to move radially outward, tightly pressing against the inner wall of the cylindrical casting. This effectively provides internal support points and force application points, allowing the force to be evenly applied to the inner wall of the casting through the top blocks, effectively preventing the casting from being scratched or damaged.

[0014] 3. By using the knob to rotate the bidirectional screw, the left and right mounting brackets slide towards each other, and the two rollers support the casting mold from below, ensuring that the casting mold remains stable and level during the demolding process and preventing it from tilting or moving.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: A demolding machine for cylindrical castings, see reference. Figures 1-5As shown, the system includes a support frame 1, a pallet 101, conveying rollers 2, a baffle 3, a casting mold 4, a cylindrical casting 5, a guide rail 6, an adjusting screw 601, a guide rod 602, a slider 7, a first guide roller 8, and a second guide roller 9. The pallet 101 is welded to the left side of the support frame 1. Multiple conveying rollers 2 are evenly spaced and rotatably mounted on the upper part of the support frame 1. The baffle 3 is welded to the left side of the support frame 1. The casting mold 4 is mounted on the pallet 101, and the cylindrical casting 5 is housed within the casting mold 4. The guide rail 6 is fixedly connected to the right side of the support frame 1. An adjusting screw 601 is rotatably mounted within the front guide rail 6, and a guide rod 602 is fixedly connected within the rear guide rail 6. A slider 7 is threaded onto the adjusting screw 601, and another slider 7 is slidably mounted on the guide rod 602. The slider 7 is located on an adjacent guide rail 6. The inner sliding mechanism includes a first guide roller 8 rotatably mounted between two sliders 7, a second guide roller 9 rotatably mounted at the lower part of the guide rail 6, a servo motor 10, a take-up roller 11, a pull rod 12, a threaded joint 13, a push plate 14, a pull ring 15, and a pull rope 16. The servo motor 10 is bolted to the front side of the middle part of the support frame 1. The take-up roller 11 is mounted on the output shaft of the servo motor 10 via a coupling. The pull rod 12 is mounted inside the cylindrical casting 5. The pull ring 15 is mounted on the right end of the pull rod 12. The pull rope 16 is connected to the pull ring 15. The pull rope 16 is wound around the first guide roller 8 and the second guide roller 9 and connected to the take-up roller 11. The threaded joint 13 is threaded to the left end of the pull rod 12. The push plate 14 is fixedly connected to the left side of the threaded joint 13. The push plate 14 is located on the left side of the cylindrical casting 5 and is in pressing contact with the cylindrical casting 5.

[0023] See Figure 1 and Figure 2 As shown, baffle 3 blocks casting mold 4 and allows cylindrical casting 5 to pass through.

[0024] When using this device, place the casting mold 4 on the support plate 101, then place the pull rod 12 inside the cylindrical casting 5, and then screw the threaded connector 13 on the left end of the pull rod 12 so that the push plate 14 on the threaded connector 13 contacts and abuts against the left side of the cylindrical casting 5. Then start the servo motor 10. The output shaft of the servo motor 10 drives the winding roller 11 to rotate and tighten the pull rope 16. The pull rope 16 passes around the first guide roller 8 and the second guide roller 9, and transmits the force to the pull rod 12. The pull rod 12 moves to the right under the pull of the pull rope 16. Since the push plate 14 at its left end is pressed against the left end face of the cylindrical casting 5, it provides a pulling force to smoothly pull the cylindrical casting 5 out of the stationary casting mold 4, completing the demolding. The adjusting screw 601 on the guide rail 6 can adjust the distance between the second guide roller 9 and the first guide roller 8 to adapt to castings of different lengths and ensure the optimal angle of the force transmission path of the pull rope 16.

[0025] Example 2: Based on Example 1, refer to Figure 3As shown, it also includes a threaded part 17, a fixed frame 18, a sliding frame 19, a scissor frame 20, a top block 21, and an adjusting nut 22. The right side of the pull rod 12 is provided with a threaded part 17, and the middle of the pull rod 12 is fixedly connected to the fixed frame 18. The threaded part 17 of the pull rod 12 is threaded with a sliding frame 19. Three scissor frames 20 are provided between the sliding frame 19 and the fixed frame 18. Top blocks 21 are provided at both ends of the scissor frames 20. The top blocks 21 are in contact with the cylindrical casting 5. The right side of the pull rod 12 is threaded with an adjusting nut 22.

[0026] Before demolding, the adjusting nut 22 is rotated, which drives the pull rod 12 to rotate. The threaded part 17 of the pull rod 12 drives the sliding frame 19 to move, so that the sliding frame 19 and the scissor frame 20 on the fixed frame 18 are unfolded, pushing the top blocks 21 at both ends to move radially outward, tightly abutting against the inner wall of the cylindrical casting 5, effectively providing internal support points and force application points, so that when pulled to the right by the pull rod 12, the force can be evenly applied to the inner wall of the casting through the top blocks 21, effectively preventing the casting from being pulled or damaged.

[0027] See Figure 1 and Figure 5 As shown, it also includes a mounting frame 23, a roller 24, and a bidirectional screw 25. The left and right sides of the support plate 101 are symmetrically provided with guide grooves 2201. The lower part of the support plate 101 is rotatably provided with a bidirectional screw 25. The left and right sides of the bidirectional screw 25 are threadedly provided with mounting frames 23. The mounting frames 23 slide in two adjacent guide grooves 2201. The upper part of the mounting frame 23 is rotatably provided with rollers 24. The two rollers 24 support the casting mold 4.

[0028] See Figure 5 As shown, it also includes a knob 26, and the end of the bidirectional screw 25 is fixedly connected to the knob 26.

[0029] See Figure 5 As shown, the knob 26 has anti-slip texture.

[0030] After the casting mold 4 is placed on the pallet 101, the two-way screw 25 is rotated by the knob 26 to drive the two mounting brackets 23 to slide synchronously towards each other in the guide groove 2201, thereby driving the rollers 24 on the upper part of the mounting brackets 23 to move. The two rollers 24 support the casting mold 4 from below, so as to adapt to casting molds 4 of different diameters, ensure that the mold remains stable and level during demolding, and prevent it from tilting or moving.
