Description

Technical Field

[0001] This invention relates to the field of multi-cylinder diesel engine block casting technology, specifically to a multi-cylinder diesel engine block casting mold and its usage method. Background Technology

[0002] A multi-cylinder diesel engine is a diesel engine equipped with more than two cylinders. This type of engine is characterized by having multiple cylinders that work together on a single crankshaft to generate power. Multi-cylinder diesel engines are classified by the number of cylinders, including two-cylinder, three-cylinder, four-cylinder, five-cylinder, and six-cylinder types. Each cylinder's working cycle includes four processes: intake, compression, power stroke, and exhaust. However, not all cylinders' power strokes occur simultaneously; rather, there is a relatively even power stroke interval, which makes the crankshaft movement of a multi-cylinder diesel engine uniform and its operation smooth.

[0003] Multi-cylinder diesel engine blocks are mainly formed by casting molds. During casting, the molten material is poured into the mold for cooling and forming. However, when the raw material is poured into the mold, it carries gas into the mold. Gas residue inside the mold can cause grooves in the formed multi-cylinder diesel engine block, thus affecting the production quality of the multi-cylinder diesel engine block. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-cylinder diesel engine cylinder block casting mold and its usage method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a multi-cylinder diesel engine cylinder block casting mold and its usage method, comprising a base plate, a mold fixedly connected to the top of the base plate, a support leg fixedly connected to the bottom of the base plate, a bending frame fixedly connected to the surface of the base plate, a hydraulic rod fixedly connected to the end of the bending frame away from the base plate, a die-casting plate fixedly connected to the telescopic end of the hydraulic rod, and a through hole formed at the bottom of the inner wall of the mold, and further comprising:

[0007] An exhaust component, comprising a sliding frame, the inner wall of which is slidably connected to the surface of a curved frame, an electric push rod fixedly connected to the surface of the sliding frame, an electric telescopic rod fixedly connected to the bottom of the sliding frame, a support plate fixedly connected to the bottom of the electric telescopic rod, and the end of the support plate away from the electric telescopic rod fixedly connected to the top of a base plate;

[0008] The bottom of the exhaust component is provided with a tumbling component;

[0009] The unloading component includes a fixed frame, the end of which is fixedly connected to the surface of a sliding frame. A rectangular frame is fixedly connected to the end of the fixed frame away from the sliding frame. A synchronization frame is fixedly connected to the bottom of the rectangular frame. A telescopic rod is fixedly connected to the top of the synchronization frame. A sealing block is fixedly connected to the top of the telescopic rod.

[0010] Furthermore, the end of the bending frame away from the base plate extends above the mold, the end of the hydraulic rod passes through the bending frame and extends to the outer end of the bending frame, the die-casting plate is located above the mold, and the surface of the die-casting plate is adapted to the inner wall of the mold.

[0011] Furthermore, the exhaust component includes a triangular frame, which is fixedly connected to the end of the electric actuator. A limit frame is fixedly connected to the surface of the triangular frame, and a circular hole frame is fixedly connected to the lower surface of the limit frame. A rotating rod is rotatably connected to the inner wall of the circular hole frame, and a grooved ring is fixedly connected to the top of the rotating rod. A stirring frame is fixedly connected to the lower surface of the rotating rod. A sliding hole is opened at the end of the triangular frame away from the electric actuator, and an elastic rod is fixedly connected to the inner wall of the triangular frame.

[0012] The end of the elastic rod away from the tripod is fixedly connected to a force-bearing rod, the end of the force-bearing rod away from the elastic rod is fixedly connected to a rubber rod, and a toothed plate is fixedly connected to the surface of the force-bearing rod.

[0013] Furthermore, the limiting frame is located at the end of the tripod near the electric actuator, the end of the rotating rod passes through the circular hole frame and extends to the outer end of the circular hole frame, the toothed plate at the end away from the force-bearing rod passes through the tripod and extends to the outer end of the tripod, the surface of the toothed plate meshes with the inner wall of the groove ring, and the end of the force-bearing rod at the end away from the elastic rod extends to the outer end of the tripod through the sliding hole.

[0014] Furthermore, the tumbling component includes an inclined plate, the top of which is hinged to the bottom of the tripod, a vertical plate is fixedly connected to the end of the inclined plate away from the tripod, and a pressing plate is fixedly connected to the top of the vertical plate.

[0015] An elastic sheet is fixedly connected to the surface of the inclined plate, and the end of the elastic sheet away from the inclined plate is hinged to the surface of the tripod.

[0016] Furthermore, the end of the elastic sheet away from the inclined plate is located below the electric actuator, the end of the inclined plate away from the tripod extends to the outer end of the tripod, and the compression plate is located below the tripod.

[0017] Furthermore, the unloading component includes a sliding rod, the surface of which is fixedly connected to the end of a rectangular frame, a contact ring is fixedly connected to the end of the sliding rod away from the rectangular frame, a spring is fixedly connected to the surface of the contact ring, and a friction ball is fixedly connected to the end of the spring away from the contact ring.

[0018] A recessed rod is fixedly connected to the bottom of the base plate, and a vertical rod is fixedly connected to the bottom of the base plate.

[0019] Furthermore, the surface of the sealing block contacts the inner wall of the through hole, the inner wall of the contact ring contacts the surface of the concave rod, the inner wall of the sliding rod contacts the surface of the plumb rod, and the end of the friction ball away from the spring contactes the inner wall of the concave hole of the concave rod.

[0020] Furthermore, a method for using a multi-cylinder diesel engine cylinder block casting mold includes the following steps:

[0021] S1: After the molten material is poured into the mold, the hydraulic rod is activated to push the die-casting plate into the mold for die casting. After the molten material enters the mold, the venting device is activated to enter the mold and stir the liquid inside the mold.

[0022] S2: When the force rod moves, it pushes the toothed plate to move. The grooved ring pushes the rotating rod to rotate inside the round hole frame as the toothed plate moves. When the rotating rod rotates, it pushes the stirring frame to rotate inside the mold. When rotating, it stirs the liquid inside the mold and treats the gas in the liquid by stirring.

[0023] S3: The slant plate will push the extrusion plate downward. When the tripod moves away from each other, the slant plate uses the elasticity of the elastic sheet to push the extrusion plate upward. When the extrusion plate moves upward, it pushes the liquid to roll inside the mold. The liquid flowing inside the mold allows the gas inside to be discharged quickly.

[0024] S4: When the contact ring moves, it pushes the friction ball to slide on the surface of the concave rod through the spring and generates vibration. The vibration is transmitted to the inside of the mold through the concave rod. The vibration is used to separate the cylinder block of the multi-cylinder diesel engine from the inner wall of the mold after die casting. At this time, the sliding frame pushes the synchronous frame to move upward, and pushes the sealing block to move through the telescopic rod during the movement.

[0025] The present invention has the following beneficial effects:

[0026] This invention involves pouring the molten material into the mold, then activating a hydraulic rod to push the die-casting plate into the mold for die casting. After the molten material enters the mold, an exhaust component is activated to stir the liquid inside, releasing any remaining gas and preventing it from affecting the casting quality of the multi-cylinder diesel engine block. As the exhaust component moves, it compresses and moves the tumbling component downwards. When the exhaust component separates, the tumbling component moves upwards, pushing the liquid upwards and accelerating gas release. After the multi-cylinder diesel engine block is die-cast inside the mold, a discharge component pushes it to the outside of the mold for unloading.

[0027] This invention uses an electric actuator to move a tripod to the top of the mold. An electric telescopic rod then pushes a sliding frame downwards. As the sliding frame moves downwards, it pushes the lower surface of the tripod into the mold. When the tripods approach each other, the rubber rods contact each other and compress the elastic rod, causing deformation. The force-bearing rod moves, pushing the toothed plate. The grooved ring, along with the toothed plate, pushes the rotating rod to rotate inside the circular hole frame. The rotating rod, in turn, pushes the stirring frame to rotate inside the mold, thus agitating the liquid inside the mold. This agitation process treats the gas in the liquid, preventing residual gas from affecting the die-casting quality of the multi-cylinder diesel engine block. However, when the tripods move away from each other, the force-bearing rod moves outwards using the elasticity of the elastic rod, and the toothed plate pushes the stirring frame to flip, further improving the gas emission efficiency.

[0028] When the tripods of this invention move closer together, the upright plates will contact each other, and the inclined plate will push the elastic sheet to deform. At the same time, the inclined plate will push the extrusion plate to move downward. When the tripods move away from each other, the inclined plate will use the elasticity of the elastic sheet to push the extrusion plate to move upward. When the extrusion plate moves upward, it will push the liquid to roll inside the mold. The liquid flowing inside the mold can quickly expel the gas inside, avoiding the gas remaining inside the liquid and affecting the die-casting quality of the multi-cylinder diesel engine cylinder block.

[0029] In this invention, the surface of the sealing block is inserted into the inside of the through hole. The sealing block needs to be pushed downward by the telescopic rod extending to its limit. When unloading the die-cast multi-cylinder diesel engine block, the tripod is located at the outer end of the mold. At this time, when the sliding frame moves downward, it pushes the rectangular frame downward through the fixed frame. When the rectangular frame moves downward, it pushes the telescopic rod downward through the synchronous frame. At this time, the rectangular frame pushes the contact ring downward through the sliding hole rod. When the contact ring moves, it pushes the friction ball to slide on the surface of the concave hole rod through the spring and generates vibration. The vibration is transmitted to the inside of the mold through the concave hole rod. The vibration is used to separate the die-cast multi-cylinder diesel engine block from the inner wall of the mold. At this time, the sliding frame pushes the synchronous frame upward, and when it moves, it pushes the sealing block to move through the telescopic rod. The sealing block can push the die-cast multi-cylinder diesel engine block to the outer end of the mold for unloading.

[0030] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-9 As shown, this invention relates to a multi-cylinder diesel engine cylinder block casting mold and its usage method, comprising a base plate 1, a mold 2 fixedly connected to the top of the base plate 1, a support leg 10 fixedly connected to the bottom of the base plate 1, a bending frame 6 fixedly connected to the surface of the base plate 1, a hydraulic rod 7 fixedly connected to the end of the bending frame 6 away from the base plate 1, a die-casting plate 8 fixedly connected to the telescopic end of the hydraulic rod 7, and a through hole 9 opened at the bottom of the inner wall of the mold 2, and further comprising:

[0045] The exhaust component 3 includes a sliding frame 20, the inner wall of the sliding frame 20 is slidably connected to the surface of the bending frame 6, an electric push rod 28 is fixedly connected to the surface of the sliding frame 20, an electric telescopic rod 21 is fixedly connected to the bottom of the sliding frame 20, a support plate 22 is fixedly connected to the bottom of the electric telescopic rod 21, and the end of the support plate 22 away from the electric telescopic rod 21 is fixedly connected to the top of the base plate 1.

[0046] A tumbling component 4 is provided at the bottom of the exhaust component 3;

[0047] The unloading component 5 includes a fixed frame 50. The end of the fixed frame 50 is fixedly connected to the surface of the sliding frame 20. A rectangular frame 54 is fixedly connected to the end of the fixed frame 50 away from the sliding frame 20. A synchronization frame 53 is fixedly connected to the bottom of the rectangular frame 54. A telescopic rod 55 is fixedly connected to the top of the synchronization frame 53. A sealing block 51 is fixedly connected to the top of the telescopic rod 55.

[0048] The end of the bending frame 6 away from the base plate 1 extends above the mold 2. After the molten material is poured into the mold 2, the hydraulic rod 7 is activated to push the die-casting plate 8 into the mold 2 for die casting. After the molten material enters the mold 2, the exhaust component 3 is activated to enter the mold 2 and stir the liquid inside the mold 2. This stirring process releases any remaining gas in the liquid, preventing it from affecting the casting quality of the multi-cylinder diesel engine block. The exhaust component 3 moves as it moves... The extrusion tumbling component 4 moves downward. When the exhaust component 3 separates, the tumbling component 4 moves upward, pushing the liquid upward and accelerating the discharge of gas. After the multi-cylinder diesel engine block is die-cast inside the mold, the unloading component 5 pushes the multi-cylinder diesel engine block to the outer end of the mold 2 to unload the die-cast multi-cylinder diesel engine block. The end of the hydraulic rod 7 passes through the bending frame 6 and extends to the outer end of the bending frame 6. The die-casting plate 8 is located above the mold 2, and the surface of the die-casting plate 8 is adapted to the inner wall of the mold 2.

[0049] The exhaust component 3 includes a triangular frame 27, which is fixedly connected to the end of the electric push rod 28. A limiting frame 29 is fixedly connected to the surface of the triangular frame 27. A circular hole frame 31 is fixedly connected to the lower surface of the limiting frame 29. A rotating rod 23 is rotatably connected to the inner wall of the circular hole frame 31. A grooved ring 24 is fixedly connected to the top of the rotating rod 23. A stirring frame 30 is fixedly connected to the lower surface of the rotating rod 23. A sliding hole 26 is opened at the end of the triangular frame 27 away from the electric push rod 28. An elastic rod 34 is fixedly connected to the inner wall of the triangular frame 27.

[0050] The end of the elastic rod 34 away from the tripod 27 is fixedly connected to a force-bearing rod 33, the end of the force-bearing rod 33 away from the elastic rod 34 is fixedly connected to a rubber rod 32, and a toothed plate 25 is fixedly connected to the surface of the force-bearing rod 33.

[0051] The limiting bracket 29 is located at the end of the tripod 27 near the electric push rod 28. When the electric push rod 28 is activated, it pushes the tripod 27 to move above the mold 2. Then, the sliding bracket 20 is pushed downwards by the electric telescopic rod 21. As the sliding bracket 20 moves downwards, it pushes the lower surface of the tripod 27 into the interior of the mold 2. When the tripods 27 approach each other, the rubber rods 32 contact each other and compress the elastic rod 34, causing deformation. The force-bearing rod 33, as it moves, pushes the toothed plate 25 to move. The grooved ring 24, along with the toothed plate 25, pushes the rotating rod 23 to rotate inside the circular hole bracket 31. As the rotating rod 23 rotates, it pushes the stirring bracket 30 to rotate inside the mold 2, thus stirring the liquid inside the mold 2. The gas in the liquid is treated by stirring to prevent gas residue inside the liquid from affecting the die-casting quality of the multi-cylinder diesel engine block. However, when the triangular frame 27 moves away from each other, the force rod 33 moves outward using the elasticity of the elastic rod 34, and pushes the stirring frame 30 to flip through the toothed plate 25, further improving the gas emission efficiency. The end of the rotating rod 23 passes through the round hole frame 31 and extends to the outer end of the round hole frame 31. The end of the toothed plate 25 away from the force rod 33 passes through the triangular frame 27 and extends to the outer end of the triangular frame 27. The surface of the toothed plate 25 meshes with the inner wall of the groove ring 24. The end of the force rod 33 away from the elastic rod 34 extends to the outer end of the triangular frame 27 through the sliding hole 26.

[0052] The tumbling component 4 includes an inclined plate 41, the top of which is hinged to the bottom of the tripod 27. An upright plate 42 is fixedly connected to the end of the inclined plate 41 away from the tripod 27, and an extrusion plate 43 is fixedly connected to the top of the upright plate 42.

[0053] An elastic sheet 40 is fixedly connected to the surface of the inclined plate 41, and the end of the elastic sheet 40 away from the inclined plate 41 is hinged to the surface of the tripod 27.

[0054] The end of the elastic plate 40 away from the inclined plate 41 is located below the electric push rod 28. When the tripod 27 moves closer to each other, the upright plates 42 will contact each other, and the inclined plate 41 will push the elastic plate 40 to deform. At the same time, the inclined plate 41 will push the extrusion plate 43 to move downward. When the tripod 27 moves away from each other, the inclined plate 41 will use the elasticity of the elastic plate 40 to push the extrusion plate 43 to move upward. When the extrusion plate 43 moves upward, it will push the liquid to roll inside the mold 2. The liquid flowing inside the mold 2 can quickly discharge the gas inside, avoiding the gas remaining inside the liquid and affecting the die casting quality of the multi-cylinder diesel engine cylinder block. The end of the inclined plate 41 away from the tripod 27 extends to the outer end of the tripod 27, and the extrusion plate 43 is located below the tripod 27.

[0055] The unloading component 5 includes a sliding rod 57, the surface of which is fixedly connected to the end of the rectangular frame 54. A contact ring 58 is fixedly connected to the end of the sliding rod 57 away from the rectangular frame 54. A spring piece 59 is fixedly connected to the surface of the contact ring 58. A friction ball 60 is fixedly connected to the end of the spring piece 59 away from the contact ring 58.

[0056] A recessed rod 56 is fixedly connected to the bottom of the base plate 1. The surface of the sealing block 51 of this invention is inserted into the inside of the through hole 9. The telescopic rod 55 needs to extend downward to its limit to push the sealing block 51 downward. When the die-cast multi-cylinder diesel engine block needs to be unloaded, the tripod 27 is located at the outer end of the mold 2. At this time, when the sliding frame 20 moves downward, it pushes the rectangular frame 54 downward through the fixed frame 50. When the rectangular frame 54 moves downward, it pushes the telescopic rod 55 downward through the synchronous frame 53. At this time, the rectangular frame 54 will push the contact ring 58 towards the sliding rod 57. As the contact ring 58 moves, it pushes the friction ball 60 to slide on the surface of the concave rod 56 via the spring piece 59, generating vibration. The vibration is transmitted to the interior of the mold 2 via the concave rod 56, and the vibration is used to separate the die-cast multi-cylinder diesel engine block from the inner wall of the mold 2. At this time, the sliding frame 20 pushes the synchronous frame 53 to move upward, and pushes the sealing block 51 to move via the telescopic rod 55. The sealing block 51 can push the die-cast multi-cylinder diesel engine block to the outer end of the mold 2 for unloading. A vertical rod 52 is fixedly connected to the bottom of the base plate 1.

[0057] The surface of the sealing block 51 contacts the inner wall of the through hole 9, the inner wall of the contact ring 58 contacts the surface of the concave rod 56, the inner wall of the sliding rod 57 contacts the surface of the vertical rod 52, and the end of the friction ball 60 away from the spring piece 59 contacts the inner wall of the concave hole of the concave rod 56.

[0058] A method for using a multi-cylinder diesel engine cylinder block casting mold includes the following steps:

[0059] S1: After the molten material is poured into the mold 2, the hydraulic rod 7 is activated to push the die-casting plate 8 into the mold 2 for die casting. After the molten material enters the mold 2, the exhaust component 3 is activated to enter the mold 2 and stir the liquid inside the mold 2.

[0060] S2: When the force rod 33 moves, it pushes the toothed plate 25 to move. The grooved ring 24 pushes the rotating rod 23 to rotate inside the round hole frame 31 as the toothed plate 25 moves. When the rotating rod 23 rotates, it pushes the stirring frame 30 to rotate inside the mold 2. When rotating, it stirs the liquid inside the mold 2 and treats the gas in the liquid by stirring.

[0061] S3: The inclined plate 41 will push the extrusion plate 43 to move downward. When the tripod 27 moves away from each other, the inclined plate 41 uses the elasticity of the elastic sheet 40 to push the extrusion plate 43 to move upward. When the extrusion plate 43 moves upward, it pushes the liquid to roll inside the mold 2. The liquid flowing inside the mold 2 can allow the gas inside to be discharged quickly.

[0062] S4: When the contact ring 58 moves, it pushes the friction ball 60 to slide on the surface of the concave rod 56 through the spring piece 59 and generates vibration. The vibration is transmitted to the inside of the mold 2 through the concave rod 56. The vibration is used to separate the cylinder block of the multi-cylinder diesel engine after die casting from the inner wall of the mold 2. At this time, the sliding frame 20 pushes the synchronous frame 53 to move upward, and pushes the sealing block 51 to move through the telescopic rod 55 during the movement.

[0063] In operation, the molten material is poured into mold 2, and hydraulic rod 7 is activated to push the die-casting plate 8 into mold 2 for die casting. After the molten material enters mold 2, exhaust component 3 is activated to enter mold 2 and stir the liquid inside, releasing any remaining gas and preventing it from affecting the casting quality of the multi-cylinder diesel engine block. As exhaust component 3 moves, it presses and moves the tumbling component 4 downwards. When exhaust component 3 separates, the tumbling component 4 moves upwards, pushing the liquid upwards and accelerating gas release. After the multi-cylinder diesel engine block is die-cast in the mold, the unloading process is completed. Material component 5 pushes the multi-cylinder diesel engine block towards the outer end of mold 2 to unload the die-cast multi-cylinder diesel engine block. Electric actuator 28 pushes the tripod 27 to the top of mold 2. Electric telescopic rod 21 pushes the sliding frame 20 downwards. As the sliding frame 20 moves downwards, it pushes the lower surface of the tripod 27 into the interior of mold 2. When the tripods 27 approach each other, the rubber rods 32 contact each other and compress the elastic rod 34, causing deformation. Force rod 33 moves, pushing toothed plate 25 to move. Groove ring 24, along with the toothed plate 25, pushes rotating rod 23 to rotate inside the circular hole frame 31. Rotating rod 23 pushes stirring frame 30 to rotate inside mold 2. During rotation, it impacts the mold... 2. The internal liquid is stirred to treat the gas in the liquid, preventing gas residue from affecting the die-casting quality of the multi-cylinder diesel engine block. When the triangular frames 27 move away from each other, the force rod 33 moves outward using the elasticity of the elastic rod 34, and pushes the stirring frame 30 to flip through the toothed plate 25, further improving the gas emission efficiency. When the triangular frames 27 move closer to each other, the upright plates 42 will contact each other, and the inclined plate 41 will push the elastic plate 40 to deform. At the same time, the inclined plate 41 will push the extrusion plate 43 to move downward. When the triangular frames 27 move away from each other, the inclined plate 41 will push the extrusion plate 43 to move upward using the elasticity of the elastic plate 40. 3. During upward movement, the liquid is pushed to tumble inside the mold 2, allowing the liquid to flow inside the mold 2 and quickly expel internal gases, preventing gas residue from affecting the die-casting quality of the multi-cylinder diesel engine block. The surface of the sealing block 51 is inserted into the through hole 9. The telescopic rod 55 needs to extend downward to its limit to push the sealing block 51 downward. When unloading the die-cast multi-cylinder diesel engine block, the tripod 27 is located at the outer end of the mold 2. At this time, when the sliding frame 20 moves downward, it pushes the rectangular frame 54 downward through the fixed frame 50. When the rectangular frame 54 moves downward, it pushes the telescopic rod 55 downward through the synchronous frame 53. At this time, the rectangular frame 54 will push the contact ring 58 downward through the sliding hole rod 57.When the contact ring 58 moves, it pushes the friction ball 60 to slide on the surface of the concave rod 56 via the spring piece 59, generating vibration. This vibration is transmitted to the interior of the mold 2 via the concave rod 56, causing the die-cast multi-cylinder diesel engine block to separate from the inner wall of the mold 2. At this time, the sliding frame 20 pushes the synchronous frame 53 upwards, and during this movement, it pushes the sealing block 51 to move via the telescopic rod 55. The sealing block 51 can then push the die-cast multi-cylinder diesel engine block to the outer end of the mold 2 for unloading.
