Description

Technical Field

[0001] The present invention relates to the technical field of mold pouring, and in particular to an automatic movable pouring equipment for casting. Background Art

[0002] Tilt-type pouring equipment is widely used because it can ensure the smoothness of molten liquid pouring and reduce defects in the pouring process during the mold pouring process; its core process requirements include: the pouring nozzle needs to have a certain height difference with the mold so that the pouring liquid enters the mold at a certain initial velocity to prevent the pouring liquid from being unable to pass through the small spacing parts in the mold due to tension; secondly, the landing point of the pouring liquid needs to be located at a specific part of the mold to ensure that it can pass through the least curved structure part along the optimal route and fill the entire mold.

[0003] by Figure 1 For example, when the number of pouring times is N, the liquid level of the solution inside the ladle is P1, and the driving component drives the ladle and the cover plate to rotate synchronously around the rotation center O to realize pouring (the cover plate is at the rotation center on the support plate). The inclination angle of the ladle increases so that the internal molten metal accurately flows through the optimal point S of the mold to the inside of the mold pouring port below under the action of potential energy. At this time, the pouring line of the solution is R. When the number of pouring times is N+, the liquid level of the solution inside the ladle will gradually decrease. At this time, the liquid level of the solution drops to P2. At this time, the angle that the ladle needs to rotate is greater than the rotation angle when the number of pouring times is N, that is, the pouring nozzle of the ladle will gradually shift backwards, and the pouring line of the solution will move from point R to point R1. Then, the point where the solution falls at the pouring port will move from point S to point S1, which will gradually increase the distance that the pouring line deviates from the pouring center S.

[0004] When the solution falling point moves from point S to point S1, the solution falls into the mold pouring port at a position deviating from point S, which will make it difficult for the solution to fill the entire mold cavity through the preset channel, leading to uneven pouring, shrinkage holes, and inclusion problems, especially for molds with complex structures, resulting in reduced casting consistency. Summary of the invention

[0005] The object of the present invention is to provide an automated movable pouring device for casting to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an automatic movable pouring equipment for casting, comprising a machine body, two support plates fixedly connected to the machine body, a cover plate being provided for rotating together on the two support plates, a pouring ladle being provided below the cover plate, a driving assembly being provided on the machine body, the driving assembly being used to drive the cover plate and the pouring ladle to rotate to complete pouring, and further comprising:

[0014] As a further solution of the present invention, the two connecting plates are rotatably connected to the cover plate and the rotation center of the connecting plate is concentric with the rotation center of the guide plate. A push rod is provided directly below the two connecting plates. The two push rods are fixedly connected to the side of the ladle. When the push rod moves forward with the ladle until it contacts the connecting plate, it pushes the two connecting plates to rotate from a vertical state to an inclined state.

DETAILED DESCRIPTION

[0041] See also Figure 1-Figure 20 The present invention provides a technical solution: an automated active pouring equipment for casting, comprising a machine body 1, two support plates 2 fixedly connected to the machine body 1, a cover plate 3 being arranged on the two support plates 2 for rotating together, a pouring ladle 4 being arranged below the cover plate 3, a driving assembly being arranged on the machine body 1, the driving assembly being used to drive the cover plate 3 and the pouring ladle 4 to rotate to complete the pouring, and also comprising: a push plate 5, the push plate 5 being slidably arranged on the cover plate 3; a guide plate 6, the opposite side being rotatably arranged on the push plate 5; a contact rod 7, being arranged on the cover plate 3 and being able to synchronously follow the movement of the cover plate 3, the side of the guide plate 6 being arranged above the contact rod 7 so that the side of the guide plate 6 is kept higher than the opposite side; a slow-moving assembly, being arranged on one side of the push plate 5 and being used to push the push plate 5 to slide forward along the cover plate 3, when the rotation inclination angle of the cover plate 3 and the pouring ladle 4 gradually increases, the distance that the slow-moving assembly pushes the push plate 5 to slide forward along the cover plate 3 will also gradually increase.

[0042] like Figure 2-Figure 5 , Figure 10-12 As shown:

[0043] The driving assembly drives the ladle 4 and the cover plate 3 to rotate around the rotation axis of the cover plate 3 so that the ladle 4 completes the dumping action. Figure 1 When the ladle 4 performs the Nth pouring, the pouring line is R, and the position where the solution falls into the mold pouring port 21 is S. After the Nth pouring, the liquid level of the solution inside the ladle 4 drops from P1 to P2. When the N+1th pouring is performed, the ladle 4 needs a larger tilt angle to complete the pouring action. However, as the rotation angle of the ladle 4 increases, the pouring nozzle of the ladle 4 will be relatively Figure 1 The middle point S gradually moves towards the direction of point S1. Figure 1 The point S1 is located on the left side of the point S, but in actual work, the point S1 is located behind the point S, which will cause the point where the solution falls to be offset;

[0044] Fig.10 The diagram shows the distance between the rotation center of the guide plate 6 and the contact rod 7 when the ladle 4 is in a horizontal state, L1>L2>L3, so as the guide plate 6 approaches the contact rod 7, the end of the guide plate 6 will gradually tilt upward;

[0045] Then, as the number of times the ladle 4 is poured increases, the ladle 4 rotates around the cover plate 3. Figure 1 When the tilting angle of the same position of point O gradually increases, the slow-moving component will push the push plate 5 to slide forward along the cover plate 3 gradually increase as the tilting angle of the ladle 4 increases, and the forward sliding distance of the push plate 5 is proportional to the increase in the tilting angle of the ladle 4. Fig.11As shown, the tilting angle relationship of a1, a2 and a3 is a1<a2<a3. When the tilting angles are a1, a2 and a3 respectively, the states of the guide plate 6 and the contact rod 7 are respectively Fig.11 As shown in Figures (a), (b) and (c), when the inclination angle of rotation from a1 to a3 gradually increases, the distance that the slow-moving component pushes the push plate 5 to slide along the cover plate 3 gradually increases, thereby gradually increasing the distance that the rotation axis of the guide plate 6 moves to the contact rod 7, that is, the distance between the rotation center of the guide plate 6 and the contact rod 7 gradually shortens, so that the guide plate 6 gradually extends forward as the rotation angle of the cover plate 3 increases and the end gradually tilts upward to compensate for the backward offset of the pouring nozzle, so that the solution flowing out of the pouring nozzle of the ladle 4 can fall to the mold pouring port 21 through the guidance of the guide plate 6, and the solution pouring line can always maintain the position of the ideal pouring line T, so that when pouring the mold, the solution falling position can continue to be in the middle position of the mold pouring port 21, thereby avoiding the problems of uneven pouring, casting defects and excessive splashing of the molten liquid caused by the solution not being able to perfectly fall into the middle position of the mold pouring port 21, which is particularly beneficial to ensure the consistency of the product for molds with complex structures;

[0046] It is worth noting that the guide plate 6 and the contact rod 7 are fitted together by the weight of the guide plate 6 and are kept fitted together with the contact rod 7 as the ladle 4 rotates, wherein the mold transport frame 22 is used to drive the multiple molds to move relative to the ladle 4 to complete the pouring one by one;

[0047] In the present invention, when the pouring nozzle and the mold pouring port 21 gradually deviate due to the increase in the inclination angle of the ladle 4 as the number of pouring times increases, the slow-moving component can control the forward movement distance of the push plate 5 according to the increase in the inclination angle of the ladle 4, and then the guide plate 6 gradually tilts up during the forward movement and guides the solution flowing out of the pouring nozzle to keep the pouring line of the solution at the ideal pouring line; thereby ensuring that the landing point can continue to be located at the optimal landing point S of the mold pouring port 21 as the inclination angle of the ladle 4 changes, thereby improving the efficiency of pouring and the consistency of the product;

[0048] As the rotation angle of the ladle 4 increases, the guide plate 6 gradually tilts up while the elongated distance increases, rather than extending in a straight line, so as to avoid the moving track of the mold below.

[0049] Embodiment 1: The slow-moving assembly includes a support rod 9, the opposite side of the support rod 9 is rotatably connected to the side wall of the push plate 5, the side of the support rod 9 is lower than the opposite side and is rotatably connected to the side wall of the support plate 2, and the rotation axis of the side of the support rod 9 is not coaxial with the rotation axis of the cover plate 3.

[0050] like Figure 1-Figure 6 As shown:

[0051] like Figure 6As shown, the support rod 9, the L5 portion of the cover plate 3, the push plate 5, and the distance L4 between the support rod 9 and the rotation axis of the cover plate 3 actually constitute a crank slider mechanism, in which the push plate 5 is a slider and L4 is a crank. It should be noted that the actual driving source is the rocker, that is, L5 attached to the cover plate 3;

[0052] As the tilting angle of the cover plate 3 and the ladle 4 increases, the distance that the support rod 9 drives the push plate 5 to slide forward along the cover plate 3 will gradually increase, and then the movement of the push plate 5 drives the guide plate 6 to move toward the contact rod 7, so that the guide plate 6 gradually moves forward and tilts.

[0053] Embodiment 2: The slow-moving assembly includes a cylinder 8 , which is fixedly connected between the cover plate 3 and the push plate 5 .

[0054] like Figure 19-20 As shown:

[0055] This embodiment achieves the same effect as the first embodiment by gradually extending the cylinder 8 and gradually moving the push plate 5 forward when the tilting angle of the ladle 4 and the cover plate 3 gradually increases. The structure is simpler, but the first embodiment does not need to add active driving components compared to the second embodiment. Therefore, the first embodiment can overcome the problem that the sensor device is easily failed due to the high temperature of the mold and the ladle 4.

[0056] The contact rod 7 is rotatably connected to two connecting plates 10 , and the two connecting plates 10 are respectively arranged on the cover plate 3 .

[0057] like Figure 4-Figure 5 As shown:

[0058] The contact rod 7 is supported by the connection plate 10, which is arranged on the cover plate 3 and can move synchronously with the cover plate 3, so that when the push plate 5 pushes the guide plate 6 to move, the friction and wear between the guide plate 6 and the contact rod 7 are reduced by rotating.

[0059] The two connecting plates 10 are both rotatably connected to the cover plate 3 and the rotation center of the connecting plate 10 is concentric with the rotation center of the guide plate 6. A push rod 11 is provided directly below the two connecting plates 10. The two push rods 11 are fixedly connected to the sides of the ladle 4. When the push rod 11 moves forward with the ladle 4 until it contacts the connecting plate 10, it will push the two connecting plates 10 to rotate from a vertical state to an inclined state.

[0060] like Figure 14-18 As shown:

[0061] The matching of the ladle 4 and the cover plate 3 is that after the ladle 4 is placed on the machine body 1, the rotation of the multiple rollers on the machine body 1 moves the ladle 4 forward to the front and then completes the connection with the cover plate 3. It is common knowledge in the prior art, such as Fig.14As shown in Figures (a) and (b), before the ladle 4 is connected to the cover plate 3, the connecting plate 10 is in a vertical state, while the guide plate 6 remains in contact with the contact rod 7 and is in a drooping state. Fig.14 As shown, at this time, the top rod 11 is located behind the connecting plate 10;

[0062] Then the ladle 4 moves forward to drive the push rod 11 to move. When the push rod 11 moves to contact the connecting plate 10, it will push the connecting plate 10 to rotate around the rotation axis and drive the contact rod 7 to rotate upward. At this time, the contact rod 7 will lift the drainage plate 6. When the front end of the push rod 11 is in front of the rotation axis of the connecting plate 10, the connecting plate 10 becomes horizontal. At this time, the drainage plate 6 is in Figure 3-Figure 5 The state shown, and then the push rod 11 moves to the front and the ladle 4 is connected with the cover plate 3;

[0063] It is worth noting that: since the matching of the ladle 4 and the cover plate 3 is performed when a new ladle 4 is replaced after the solution inside the ladle 4 is used up, the cover plate 3 and the ladle 4 are both in a horizontal position when the matching is performed. Therefore, when the solution inside the ladle 4 is used up, the ladle 4 and the cover plate 3 need to be rotated to the initial state, that is, horizontal, and then the ladle 4 is separated from the cover plate 3 and replaced with a new ladle 4. That is, when the solution in the ladle 4 is used up, the ladle 4 needs to be rotated from an inclined state to a horizontal state, and then separated from the cover plate 3. When the cover plate 3 is separated from the ladle 4, the connecting plate 10, the contact rod 7 and the drain plate 6 will be in a horizontal position again Fig.15 state, at this time, the drain plate 6 is in a drooping state, which can facilitate the dripping of the residual solution above, and a release agent can be applied to the surface of the drain plate 6 before use to reduce the residue.

[0064] Two first fixing members 12 are fixedly connected to the side of the push plate 5, and a second fixing member 13 is arranged above the two first fixing members 12. The two first fixing members 12 and the two second fixing members 13 are used to clamp the rotating shaft of the guide plate 6. A wedge rod 14 is arranged above the two push rods 11. The wedge rod 14 is slidably connected to the push plate 5 in the vertical direction. A spring 15 is fixedly connected between the wedge rod 14 and the push plate 5. The wedge rod 14 can be lifted up by the push rod 11. Two first rack rods 16 are fixedly connected, and the two first rack rods 16 are both meshed with gears 17. The two gears 17 are rotatably connected to the inner wall of the push plate 5. The two gears 17 are both meshed with second rack rods 18. The two second rack rods 18 are both L-shaped and are slidably connected to the push plate 5. The top ends of the two second rack rods 18 are respectively located above the two second fixing members 13. The two second fixing members 13 are both rotatably connected to the push plate 5. The rotating axes of the two second fixing members 13 are sleeved with torsion springs 19.

[0065] like Figure 5 , Figure 7-Figure 9 as well as Figure 14-18 As shown:

[0066] Replacement and removal of guide plate 6:

[0067] In the Fig.14 As shown in the middle figure (a), that is, when the ladle 4 and the cover plate 3 are not connected, the top rod 11 is behind the connecting plate 10. At this time, the connecting plate 10 and the guide plate 6 are both in a drooping state. At this time, the first fixing member 12 and the second fixing member 13 are in a Fig.15 The separated state shown in the figure, and the second fixing member 13 is in an inclined state, which makes it easy to remove the guide plate 6;

[0068] When the cover plate 3 and the ladle 4 are connected, the push rod 11 will push the connecting plate 10 from the vertical state to the horizontal state. After the push rod 11 moves to contact the inclined surface at the bottom of the wedge rod 14, it will push the wedge rod 14 to slide up along the push plate 5 and stretch the spring 15. When the wedge rod 14 rises, it will drive the first rack rod 16 to rise and mesh with the gear 17. At this time, the gear 17 will drive the second rack rod 18 to slide down along the push plate 5. When the second rack rod 18 slides down, its end will press down the second fixing member 13, so that the second fixing member 13 limits the rotation axis of the guide plate 6, thereby completing the fixation of the guide plate 6. After fixation, Fig.17 As shown, when the top rod 11 is separated from the wedge rod 14, the first fixing member 12 and the second fixing member 13 will release the fixing of the guide plate 6, thereby facilitating the removal of the guide plate 6, that is, Figure 15-16 Status shown.

[0069] Balls are rotatably arranged on the inner walls of the first fixing member 12 and the second fixing member 13 .

[0070] The ball bearing is common knowledge in the prior art, and is used to reduce friction when the guide plate 6 rotates. It is common knowledge in the prior art and does not need to be described in detail here or in the drawings.

[0071] A blocking portion 20 is fixedly connected to the guide plate 6 .

[0072] like Fig.13 As shown:

[0073] The blocking portion 20 is used to prevent excessive backflow of the solution remaining on the surface of the drain plate 6 when the cover plate 3 is connected to the ladle 4 .
