Existing gravity casting mainly includes two categories, including tilting gravity casting and fixed gravity casting. Compared with fixed type, tilting gravity casting can be used to cast metal components with more complex structures, such as the wheel hub structure of an automobile. In the existing tilting gravity casting machine, a cylinder is usually used to push the middle casting structure to tilt and flip, such as the content shown in the patents with application publication number CN114472861A and application publication number CN117324591A. In the above patents, hydraulic elements are used to achieve the push. However, for the case where the hydraulic element controls the tilting, on the one hand, when the hydraulic element is pushed to different angles, due to the change in the relative position of the hydraulic element and the rotating part, the required thrust is also constantly changing, making the tilting process not stable enough.

[0021] A square column is also provided between the upper support 113 and the lower support 114 of the frame structure 11 to support and connect the upper support and the lower support to make it more stable; the upper support 113 is also fixedly connected to the upper end surface of the gear disc 3 through the square column.

[0022] A power assembly 111 for controlling the flipping of the upper mold structure 12 is arranged on the top of the frame structure 11; in this example, the power assembly 111 is a hydraulic motor 1111 and a turbine reducer 1112, which have a mechanical self-locking function. The hydraulic motor 1111 is connected to the upper mold structure 12 through the turbine reducer 1112, which effectively prevents the upper mold structure 12 from accelerating the flipping action due to the influence of gravity after flipping to a certain angle, causing a collision and an accident; the upper mold structure 12 is also rotatably connected to the frame structure 11 through a rotating shaft; when the hydraulic motor 1111 is working, the upper mold structure 12 is controlled to flip around the rotating shaft. The upper mold structure 12 includes an upper mold connecting plate 121 and an upper mold 122, wherein the upper mold 122 is fixedly arranged on the upper mold connecting plate 121; the upper mold connecting plate 121 is located above the frame structure 11, and the upper mold connecting plate 121 is rotatably connected to the frame structure 11; the upper surface of the frame structure 11 is provided with a hollow hole for passing the upper mold 122; when the upper mold connecting plate 121 is turned down, the two ends of the upper mold connecting plate 121 are placed on the edge area of ​​the hollow hole. The upper mold structure 12 is also provided with a fin-shaped card plate 123 for limiting the maximum flipping angle; the card plate 123 is arranged above the upper mold connecting plate 121, and in this example, the card plate 123 is arranged near the part of the upper mold connecting plate 121 near the rotating shaft; when the card plate 123 abuts against the upper surface of the upper mold connecting plate 121 of the frame structure 11, the upper mold structure 12 flips to the maximum angle.

[0023] The upper surface of the frame structure 11 is also provided with a locking assembly 112 for locking the upper mold structure 12; the locking assembly 112 includes a first oil cylinder 1121 and a locking plate 1122; wherein the locking plate 1122 is fixedly arranged at the movable end of the first oil cylinder 1121, and the locking plate 1122 is arranged close to the upper mold connecting plate 121; the locking plate 1122 is also provided with a stepped structure 1123 corresponding to the edge of the upper mold connecting plate 121, and the stepped structure 1123 is used to clamp the upper mold connecting plate 121. When the first oil cylinder 1121 in the locking assembly 112 pushes the locking plate 1122 to approach the upper mold connecting plate 121, the stepped structure 1123 at the edge of the locking plate 1122 gradually clamps into the edge of the upper mold connecting plate 121, until the stepped structure 1123 abuts against the edge of the upper mold connecting plate 121, thereby achieving the clamping connection between the two. In this example, in order to ensure that when the first oil cylinder 1121 of the locking assembly 112 retreats, the locking plate 1122 is fully away from the top of the upper mold connecting plate 121 to avoid interference with the flipping of the upper mold connecting plate 121, a second limit switch 1127 is also arranged around the first oil cylinder 1121; in this example, the locking plate 1122 is slidably arranged in a square sliding tube 1124 with two ends passing through, and the first oil cylinder 1121 in the locking assembly 112 is located on the side of the sliding tube 1124 away from the upper mold connecting plate 121, and the second limit switch 1127 is fixedly arranged above the sliding tube 1124, and a sliding hole 1125 connected to the interior of the sliding tube 1124 is also arranged above the sliding tube 1124, and a second limit rod 1126 is arranged on the locking plate 1122 to pass through the sliding hole 1125 and cooperate with the second limit switch 1127. The purpose of the locking assembly 112 is to ensure that after the upper mold structure 12 is flipped into place, it is fully fitted with the lower mold structure to ensure the precision requirement of mold closing.

In this example, the first limit switch 22 on the base 2 is arranged near the servo motor, because the first limit switch 22 must cooperate with the toothed disc, and the toothed disc and the servo motor are meshed and connected. In addition, the first limit switch 22 is arranged in the slide groove, and the two first limit switches 22 can slide in the slide groove respectively, adjust the distance between the two, and then adjust the rotation angle range of the toothed disc to achieve the control of the tilt angle of the tilting body. In addition, in order to protect the servo motor, a protective cover is also arranged on its outside.

[0025] The base 2 is also provided with a proximity sensor 23 for determining the position of the toothed disc 3. A raised sensing portion 32 corresponding to the proximity sensor 23 is provided at a set angle on the toothed disc 3. In this example, it is used to sense the initial position of the rotation of the toothed disc 3, that is, the zero-degree position when the toothed disc 3 faces directly downward, and the tilting body 1 is in a vertical state. It should be noted that in some other embodiments, the proximity sensor 23 can also be set at different positions to correspond to different initial angles of the toothed disc 3, so that the rotation inclination angle of the toothed disc 3 can be accurately controlled to meet different process requirements of different products.

[0026] During the implementation process, by setting the tilting body 1 and the base 2 to be connected through the meshing transmission connection of the gear plate 3, on the one hand, it is convenient to control the rotation angle of the tilting body 1 relative to the base 2, and on the other hand, the gear plate 3 is more stable during the rotation process and the rotation angle range is larger; by setting a clamping plate 123 on the upper mold structure 12, the maximum angle of the upper mold structure 12 to flip open is limited; by setting a locking structure, the upper mold structure 12 is locked when closed to ensure the stability of the mold closing of the upper mold structure 12 and the lower mold structure 13.

[0027] like Figure 12~Figure 15 As shown, it also includes a hydraulic station 4 for providing liquid oil to the cylinders, and the hydraulic station 4 is respectively connected to a number of cylinders arranged on the tilting body 1 and the base 2. The hydraulic station 4 includes a box body 41 for containing circulating liquid oil, and the box body 41 is provided with an outflow pipe 42 for the liquid oil to flow out and an inflow pipe 43 for the liquid oil to flow in. After the circulating liquid oil flows into the box body 41 through the inflow pipe 43, it flows out of the box body 41 through the outflow pipe 42, and is sent to the servo power structure outside the box body 41, and finally returns to the inflow pipe 43 to complete the cycle; a partition 44 is provided inside the box body 41, and the inflow pipe 43 and the outflow pipe 42 of the liquid oil are respectively located on both sides of the partition 44; the partition 44 divides the space inside the box body 41 into two parts, and the two areas are interconnected, so as to help realize the mutual flow of liquid oil in some areas; in this example, the partition 44 is vertical The state is located in the box body 41, and the bottom edge of the partition 44 is connected to the bottom plate of the box bottom; the top edge of the partition 44 is spaced a set distance from the top plate of the box body 41 for the liquid oil to flow through and realize the connection between the two areas; wherein the partition 44 is close to the side of the inflow pipe 43, and the inflowing liquid oil is first precipitated on this side, and the relatively cleaner upper liquid oil flows into the other side of the partition 44, and enters the external servo power structure through the outflow pipe 42. In addition, when cleaning, it is mainly necessary to clean the side close to the inflow pipe 43, so as to reduce the cleaning space and facilitate cleaning; it should be noted that the inflow pipe 43 and the outflow pipe 42 are respectively arranged in the box body 41 away from the partition 44, so as to facilitate the precipitation of the liquid oil during the flow process.

[0028] A gap is left between at least one of the two ends of the bottom edge of the partition 44 and the inner wall of the box body 41 for liquid oil to flow through, so that when the liquid level of the liquid oil in the box body 41 is lower than the height of the partition 44, the liquid oil on both sides of the partition 44 can also flow smoothly; and impurities are blocked to a certain extent, so that more impurities remain in the partition 44 on the side close to the inflow pipe 43.

[0029] An oil suction filter 421 is also provided on the outflow pipe 42. The oil suction filter 421 is located inside the box body 41 and is arranged close to the bottom of the box body 41.
