Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a demolding device for casting diesel engine blocks. Background Technology

[0002] After the diesel engine block is cast, it needs to be demolded. In the existing technology, a push cylinder is usually installed at the bottom of the lower mold. The bottom surface of the mold cavity of the lower mold has a through hole, and the piston rod of the push cylinder passes through the through hole. After casting is completed, the upper mold moves upward and separates from the lower mold. The push cylinder extends and pushes the casting out of the mold cavity. Finally, the workers remove the casting.

[0003] In addition to bearing the adhesive force between the casting and the lower mold, the casting also needs to withstand its own weight. It is difficult to eject the casting by the push cylinder. Moreover, the casting is easily unstable after being ejected and supported by the push cylinder. Furthermore, the casting needs to be moved away after being ejected, which is inconvenient for demolding. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a demolding device for diesel engine block casting, which makes it easier to eject the casting and avoids the situation of unstable support of the casting. In addition, it eliminates the need to move the casting between the lower mold and the upper mold, making demolding more convenient.

[0005] A diesel engine block casting demolding device according to an embodiment of the present invention includes a frame, an upper mold, a lower mold, a push cylinder, a material conveying component, and a drive mechanism. The upper mold is vertically and movably mounted on the frame, and the lower mold is rotatably mounted on the frame about a horizontal axis. The lower mold has a parting surface, a mold cavity, and a through hole communicating with the mold cavity. The lower mold can rotate to a first state in which the parting surface faces upward and is horizontally positioned, and to a second state in which the parting surface faces downward and is inclined relative to the horizontal direction. The push cylinder is located on the lower mold, and the piston rod of the push cylinder passes through the through hole. The lower mold is used to eject the casting from the mold cavity. The conveyor is movably connected to the lower mold and has a conveying slide. The conveyor is movable relative to the lower mold to a first position that exposes the mold cavity and a second position that covers the mold cavity. When the lower mold is in the second state and the conveyor is in the second position, the conveying slide is inclined relative to the horizontal direction to receive the casting ejected from the mold cavity and allow the casting to slide downward. The drive mechanism is located on the frame and connected to the lower mold to drive the lower mold to rotate.

[0006] The diesel engine block casting demolding device according to the embodiment of this utility model has at least the following beneficial effects:

[0007] When casting a diesel engine block, the drive mechanism drives the lower mold to rotate to the first state and moves the material conveyor to the first position. Then, the upper mold is lowered to fit against the parting surface of the lower mold. Finally, casting liquid is injected into the mold cavity, and the casting liquid cools to form the casting. During demolding, the upper mold is raised to separate from the lower mold. Then, the material conveyor is moved to the second position to cover the mold cavity of the lower mold. Then, the drive mechanism drives the lower mold to rotate to the second state. In this state, the mold cavity faces downward, the parting surface faces downward and is inclined relative to the horizontal direction. At the same time, the material conveyor is located below the mold cavity and the material conveying slide is inclined relative to the horizontal direction. Then, the push cylinder is activated, driving the piston rod to push the casting out of the mold cavity. The casting can then fall into the material conveying slide of the material conveyor and slide down to the ground along the inclined direction of the material conveying slide. In this application, when the ejector cylinder ejects the casting, it does not need to bear the weight of the casting, and the casting can also fall out of the mold cavity by its own weight, making ejection simpler and less labor-intensive, and avoiding damage caused by excessive force on the ejector cylinder. In addition, after the casting is removed from the mold cavity, it can fall directly to the material conveying slide of the material conveying component without the need for support by the ejector cylinder, which can avoid safety accidents caused by unstable support of the casting. Furthermore, after the casting falls to the material conveying slide of the material conveying component, it can slide directly to the ground without manual removal, resulting in higher casting efficiency. In addition, when the lower mold needs to be flipped after casting, the material conveying component covers the mold cavity of the lower mold, which can prevent the casting from sliding out of the mold cavity at will during the lower mold flipping process and causing safety accidents.

[0008] According to some embodiments of the present invention, the material conveying component can be extended and retracted along the material conveying direction of the material conveying slide.

[0009] According to some embodiments of the present invention, the feeding component includes a first feeding trough and a second feeding trough. Both the first feeding trough and the second feeding trough are formed with the feeding slide. The surface of the feeding slide of the second feeding trough is attached to the outer surface of the first feeding trough, and the second feeding trough can slide and adjust relative to the first feeding trough along the feeding direction of the feeding slide.

[0010] According to some embodiments of the present invention, one side of the first feeding trough is rotatably connected to one side of the lower mold, and a connecting part is provided on the opposite side of the first feeding trough, the connecting part being used for detachable connection with the lower mold.

[0011] According to some embodiments of the present invention, when the lower mold is in the first state and the material conveyor is in the first position, the material conveyor is located outside one side of the lower mold.

[0012] According to some embodiments of the present invention, the frame is provided with a first support portion, and when the lower mold is in the first state and the material conveyor is in the first position, the material conveyor is supported on the first support portion.

[0013] According to some embodiments of the present invention, the frame is provided with a second support portion, the second support portion comprising:

[0014] A support plate is rotatably connected to the frame about a horizontal axis;

[0015] A hydraulic cylinder is provided, with its two ends hinged to the support plate and the frame, respectively, to drive the support plate to rotate.

[0016] The support plate can rotate to support the lower mold in the first state, and can also move away from the rotation path of the lower mold.

[0017] According to some embodiments of the present invention, the frame is provided with a plurality of vertically penetrating guide holes, and the top of the upper mold is provided with a plurality of vertically extending guide rods, the plurality of guide rods being respectively inserted through the plurality of guide holes.

[0018] According to some embodiments of the present invention, multiple push cylinders are provided, and when the lower mold is in the first state, the multiple push cylinders are arranged side by side.

[0019] According to some embodiments of the present invention, the driving mechanism includes two driving cylinders, one end of the two driving cylinders is hinged to the frame, and the other end of the two driving cylinders is respectively hinged to opposite sides of the lower mold, and the arrangement direction of the two driving cylinders is parallel to the extension direction of the rotation axis of the lower mold.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] The following is for reference. Figures 1 to 5 Describes a diesel engine block casting demolding device according to an embodiment of the present invention.

[0040] refer to Figures 1 to 5 As shown, the diesel engine block casting demolding device according to an embodiment of the present utility model includes a frame 100, an upper mold 200, a lower mold 300, a push cylinder 400, a material conveying component 500, and a drive mechanism 600.

[0041] The upper mold 200 is vertically mounted on the frame 100. Specifically, a lifting cylinder 700 can be provided at the top of the frame 100, with its bottom end connected to the upper mold 200 to drive the upper mold 200 to rise and fall. This allows the upper mold 200 to descend to fit against the lower mold 300, or to rise to separate from the lower mold 300. Alternatively, the upper mold 200 can be raised and lowered using a motor-driven screw mechanism. The upper mold 200 may be provided with an injection hole for injecting casting liquid into the mold cavity 302.

[0042] The lower mold 300 is rotatably mounted on the frame 100 about a horizontal axis. The lower mold 300 has a parting surface 301, a mold cavity 302, and a through hole 303 communicating with the mold cavity 302. The lower mold 300 can rotate to a first state in which the parting surface 301 faces upward and is horizontally positioned. In this state, the opening of the mold cavity 302 faces upward, facilitating the descent of the upper mold 200 to fit against the parting surface 301 of the lower mold 300, thereby facilitating casting. The through hole 303 is located at the bottom end of the lower mold 300. The lower mold 300 can rotate to a second state in which the parting surface 301 faces downward and is inclined relative to the horizontal direction. In this state, the opening of the mold cavity 302 faces downward.

[0043] The push cylinder 400 is located in the lower mold 300. The piston rod of the push cylinder 400 passes through the through hole 303 to push out the casting in the mold cavity 302. The push cylinder 400 can be a hydraulic cylinder or a pneumatic cylinder, depending on the actual needs.

[0044] The material conveyor 500 is movably connected to the lower mold 300. The material conveyor 500 forms a material conveying slide 501. The material conveyor 500 can move relative to the lower mold 300 to a first position that exposes the mold cavity 302. When the lower mold 300 is in the first state and the material conveyor 500 is in the first position, the material conveyor 500 is not located between the upper mold 200 and the lower mold 300 to avoid interfering with the movement of the upper mold 200. The material conveyor 500 can move relative to the lower mold 300 to a second position that covers the mold cavity 302. When the lower mold 300 is in the second state and the material conveyor 500 is in the second position, the material conveyor 500 is partially located below the mold cavity 302 of the lower mold 300, and the material conveying slide 501 is inclined relative to the horizontal direction to receive the casting pushed out from the mold cavity 302 and allow the casting to slide downward. The drive mechanism 600 is provided on the frame 100 and connected to the lower mold 300 to drive the lower mold 300 to rotate.

[0045] When a diesel engine block needs to be cast, the drive mechanism 600 drives the lower mold 300 to rotate to the first state and moves the material conveyor 500 to the first position. Then, the upper mold 200 is lowered to fit the parting surface 301 of the lower mold 300. Finally, casting liquid is injected into the mold cavity 302, and the casting liquid cools to form a casting. During demolding, the upper mold 200 is raised and separated from the lower mold 300. Then, the material conveyor 500 is moved to the second position to cover the mold cavity 302 of the lower mold 300. Then, the drive mechanism 600 drives the lower mold 300 to rotate to the second state. In this state, the mold cavity 302 faces downward, the parting surface 301 faces downward and is inclined relative to the horizontal direction. At the same time, the material conveyor 500 is located below the mold cavity 302 and the material conveying slide 501 is inclined relative to the horizontal direction. Then, the push cylinder 400 is activated to drive the piston rod to push the casting out of the mold cavity 302. The casting can then fall into the material conveying slide 501 of the material conveyor 500 and slide down to the ground along the inclined direction of the material conveying slide 501.

[0046] In this application, when the push cylinder 400 ejects the casting, it does not need to bear the weight of the casting, and the casting can also fall out of the mold cavity 302 by its own weight, making the ejection simpler and less labor-intensive, and avoiding damage to the push cylinder 400 due to excessive force. In addition, after the casting is removed from the mold cavity 302, it can fall directly to the conveying slide 501 of the conveying component 500 without the need for support by the push cylinder 400, which can avoid safety accidents caused by unstable support of the casting. Furthermore, after the casting falls to the conveying slide 501 of the conveying component 500, it can slide directly to the ground without manual removal, resulting in higher casting efficiency. In addition, when the lower mold 300 needs to be flipped after casting demolding, the conveying component 500 covers the mold cavity 302 of the lower mold 300, which can prevent the casting from sliding out of the mold cavity 302 at will during the flipping of the lower mold 300 and causing safety accidents.

[0047] It should be noted that the first and second positions to which the material conveyor 500 moves are not fixed positions relative to the frame 100, but rather positional relationships relative to the lower mold 300.

[0048] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the conveying component 500 can be extended and retracted along the conveying direction of the conveying slide 501. Thus, when the lower mold 300 is flipped, the conveying component 500 can retract, thereby avoiding interference with the flipping of the lower mold 300 and making the flipping of the lower mold 300 more convenient. After the lower mold 300 is flipped to the second state, the conveying component 500 can be extended, so that the bottom end of the conveying component 500 is closer to the ground, making it more convenient to convey the casting.

[0049] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the material conveying component 500 includes a first material conveying trough 502 and a second material conveying trough 503. Both the first material conveying trough 502 and the second material conveying trough 503 are formed with material conveying slides 501. The surface of the material conveying slide 501 of the second material conveying trough 503 is attached to the outer surface of the first material conveying trough 502. The outer surface of the first material conveying trough 502 is the surface of the side opposite to the material conveying slide 501 of the first material conveying trough 502. The second material conveying trough 503 can slide and adjust relative to the first material conveying trough 502 along the material conveying direction of the material conveying slide 501. For example, both the first conveying trough 502 and the second conveying trough 503 may include a bottom plate and two side plates. The two side plates are located on opposite sides of the bottom plate. A conveying slide 501 can be formed between the bottom plate and the two side plates. The surface of the bottom plate of the second conveying trough 503 that is close to the corresponding conveying slide 501 can be attached to the surface of the bottom plate of the first conveying trough 502 that is away from the corresponding conveying slide 501. The surface of the side plate of the second conveying trough 503 that is close to the corresponding conveying slide 501 can be attached to the surface of the side plate of the first conveying trough 502 that is away from the corresponding conveying slide 501. A slide rail can be provided on the surface of the side plate of the first conveying trough 502 that is away from the corresponding conveying slide 501. The side plate of the second conveying trough 503 can be slidably mounted on the slide rail.

[0050] In this embodiment, the material conveyor 500 is configured in such a way that the telescopic adjustment effect is better.

[0051] It should be noted that the material conveying component 500 can also be adjusted in other ways. For example, the first material conveying trough 502 can have a receiving cavity, and the second material conveying trough 503 can be slidably installed in the receiving cavity.

[0052] refer to Figures 1 to 4As shown, in some embodiments of this utility model, one side of the first feeding trough 502 is rotatably connected to one side of the lower mold 300, and the opposite side of the first feeding trough 502 is provided with a connecting part 504, which is used for detachable connection with the lower mold 300. The first feeding trough 502 can rotate to position the feeding component 500 relative to the lower mold 300 in a first position or a second position. The connecting part 504 may be provided with a first connecting hole, and the lower mold 300 may be provided with a corresponding second connecting hole. When the first feeding trough 502 rotates to position the feeding component 500 relative to the lower mold 300 in the second position, the first connecting hole and the second connecting hole are aligned, and then the fastener can be installed.

[0053] In this embodiment, this configuration not only allows the material conveying component 500 to move quickly to the first and second positions relative to the lower mold 300, but also allows it to be locked when it is in the second position, preventing the material conveying component 500 from rotating arbitrarily and affecting the coverage of the mold cavity 302 and the material conveying.

[0054] It should be noted that the connecting part 504 and the lower mold 300 can also be snap-fitted together.

[0055] It is understandable that the material feeder 500 can also be in other ways, for example, it can be slidably connected to the lower mold 300 and can switch between the first position and the second position by sliding.

[0056] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, when the lower mold 300 is in the first state and the material conveyor 500 is in the first position, the material conveyor 500 is located outside one side of the lower mold 300. That is, it is not on the path of the upper mold 200's lifting and lowering. In this way, the material conveyor 500 can be prevented from interfering with the lifting and lowering of the upper mold 200.

[0057] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, the frame 100 is provided with a first support part 101. When the lower mold 300 is in the first state and the material conveyor 500 is in the first position, the material conveyor 500 is supported on the first support part 101. By providing the first support part 101, when the lower mold 300 is in the first state and the material conveyor 500 is in the first position, the first support part 101 can support the material conveyor 500 and prevent the material conveyor 500 from swinging arbitrarily.

[0058] refer to Figures 1 to 3As shown, in some embodiments of this utility model, the frame 100 is provided with a second support part 102, which includes a support plate 103 and a support cylinder 104. The support plate 103 is rotatably connected to the frame 100 about a horizontal axis. The two ends of the support cylinder 104 are respectively hinged to the support plate 103 and the frame 100 to drive the support plate 103 to rotate. The support plate 103 can rotate to support the lower mold 300 in the first state and move away from the rotation path of the lower mold 300.

[0059] When the lower mold 300 rotates to the first state, the support cylinder 104 drives the support plate 103 to rotate to a near-horizontal state. The support plate 103 can support the bottom of the lower mold 300, avoiding excessive force exerted by the lower mold 300 on the drive mechanism 600 during the casting process, which could damage the drive mechanism 600. When the lower mold 300 needs to rotate from the first state to the second state, the support cylinder 104 drives the support plate 103 to move away from the rotation path of the lower mold 300, avoiding interference with the rotation of the lower mold 300.

[0060] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, the frame 100 is provided with multiple vertically penetrating guide holes, and the top of the upper mold 200 is provided with multiple vertically extending guide rods 201, which are respectively inserted through the multiple guide holes. In this embodiment, through the cooperation of the guide rods 201 and the guide holes, the upper mold 200 can be precisely raised and lowered vertically, thereby enabling the lower mold 300 to precisely cooperate with the upper mold 200, resulting in better casting quality.

[0061] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, multiple push cylinders 400 are provided, and when the lower mold 300 is in the first state, the multiple push cylinders 400 are arranged side by side. In this way, when the push cylinders 400 extend, the force applied to the casting is more uniform, the effect of ejecting the casting from the mold cavity 302 is better, and the casting is less likely to be damaged.

[0062] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, the drive mechanism 600 includes two drive cylinders. One end of each drive cylinder is hinged to the frame 100, and the other end is respectively hinged to opposite sides of the lower mold 300. The arrangement direction of the two drive cylinders is parallel to the extension direction of the rotation axis of the lower mold 300. In this embodiment, this arrangement not only improves the effect of driving the lower mold 300 to rotate, but also makes the support of the lower mold 300 more stable.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
